In addition, the City is investigating opportunities to manage by purchase or through the City' s zoning authority the land use activities on a 25-acre area of land referred to as "Planning Mode." This area located adjacent to the park west of Sully-Miller Lake has been found to be of significance to the orderly development and use of the park. The City has designated this area "Planning Mode" and directed City staff to conduct a land use analysis of the area. That analysis, available from the City, considered four land use alternatives. The impacts of those alternatives are assessed in this EIR. The following discussion provides a summary of the salient environmental impacts associated with the proposed project. For a detailed discussion the reader is referred to the main text of this Environmental Impact Report. • PARK IMPACTS - SUMMARY Soils and Geology Existing preliminary information indicates potentially severe geotechnical hazards may exist in several locations within Huntington Central Park con- straining the construction of new structures. Additionally, completed land- fill areas in the park may be subject to differential subsidence for a period of up to 100 years. Potentially active branch faults of the Newport-Inglewood System have been identified within the boundaries of the project site. The Bolsa-Fairview Fault traverses the southerly portion of the project site in a southeasterly direction. The location of this fault may impact development of the Planning Mode area. • -1- • Water Quality and Hydrology The lakes existing within the boundaries of Central Park are beset by numer- ous existing and potential problems of which the most significant are: o Bank erosion. o Water level fluctuation. o Nutrient inputs. o Groundwater seeps. o Debris inflow. o Oxygen concentrations. o Water clarity. Biology Development of the ball field complex will result in the loss of 35 to 75 trees along the westerly boundary of the proposed ball field complex. The loss in trees will be mitigated with the development of a landscape buffer near the same boundaries and around the periphery of the ball field complex. Land Use and Planning The most significant impacts arising from the proposed project, relative to land use, are: o Ball field complex impacts upon the nearby residential neighborhood. o Ball field complex impacts upon the adjoining nature area. Archaeological Resources The existing midden area contains an archaeological site (Ca-ORA-82) which is considered extremely significant where numerous artifacts and human skele- tal materials dating back to 3000 B.C. have been uncovered. The EIR text identifies investigation measures to preserve the site. r Traffic and Circulation Arterial roads providing access to the park are to be at, or near, capacity by 1995 with, or without, the project. However, implementation of the pro- ject in the immediate future would necessitate the improvement of Golden West Street to its maximum designed width and all Streets bordering the project should be improved to their respective minimum half-width dimension. In addition, the project will require several traffic control measures to minimize associated traffic concerns. i -2- • Climate and Air Quality The project will not significantly degrade air quality on a local or regional basis. Grading of the site will produce exhaust emissions from construction equipment and fugitive dust generated by earth movement. Subsequent to construction the primary ambient air quality impacts will be that of carbon monoxide associated with emissions of vehicles carrying park users to the site and other vehicles utilizing the major thoroughfares through the Park area (Golden West Street, Talbert Avenue, etc. ). PLANNING MODE IMPACTS - SUMMARY r Soils and Geology The Bolsa-Fairview Fault traverses the southerly portion of the Planning Mode. This fault system is considered active and has been classified as a High Risk fault in the City's General Plan. Land Use and Planning The "no project" alternative would result in the continuation of the existing or similar use of the property, essentially that of the mushroom farm. This use has been found to be incompatible with the adjoining park from a visual , odor, and possibly fly breeding standpoint. Two of the four land use alternatives (garden office and residential ) result in varying degrees of land use compatibility with the estate residential land use being more compatible with the park than garden office/restaurant due primarily to the lesser intensity of development and use associated with residential . The recreational vehicle park would be compatible to the extent that it would provide a supplemental use to the park. The nursery/tree farm use would provide general compatibility with the park due to its open space nature. Traffic and Circulation Traffic generated by the various land use alternatives considered vary from 6,210 to 10,480 vehicle trips per day. The office/restaurant use poses the greatest impact upon the area due to its regional orientation as opposed to other uses which would be expected to generate local traffic. • -3- Fiscal Impact Over a ten-year period the garden office and nursery/tree farm land uses each reflect greater City costs compared to revenues received to maintain necessary public services. Environmental Health Generally the project will result in an increased noise level due to the noise generated by traffic. Moreover, the ball field complex will signifi- cantly increase the noise levels upon a nearby residential neighborhood and the existing nature area. Nighttime use of ball field lighting will also pose potential impact upon the use of residential property. These impacts and mitigation measures are discussed in greater detail in the text of the EIR. r i -4- • • CHAPTER 1.0 PROJECT DESCRIPTION • • • • • 1.0 PROJECT DESCRIPTION 1.01 INTRODUCTION The preparation of this Environmental Impact Report (EIR) was authorized by the City Council of the City of Huntington Beach in. a contract executed by and between the City of Huntington Beach and Willdan Associates. Comments regarding the preparation and content of the Draft Environmental Impact Report may be submitted in writing and should be addressed to: Mr. James R. Barnes, Associate Planner City of Huntington Beach, Development Services 2000 Main Street Huntington Beach, California 92648 Telephone: (714) 536-5272 Envista, a division of Willdan Associates, is the primary environmental con- sultant responsible for the preparation of this Environmental Impact Report. The format follows closely, and is intended to comply with, the requirements of the California Environmental Quality Act (CEQA) comprising Chapters 1, 2, 2.5, 2.6, 3, 4, 5, and 6 of Division 13 of the Public Resources Code. Guidance in the preparation of this EIR was provided by the City of Huntington Beach - Development Services Department in the form of an Initial Study (Appendix A). The Initial Study delineates areas of primary concern includ- ing: topographic, geologic, and seismic hazards; air quality; water drainage and water quality; plant and animal species; noise; light and glare; land i use; vehicular and pedestrian traffic; public services; utilities; recrea- tional facilities; and archaeology. The Initial Study forms the basis for the preparation of this EIR. Assisting Envista is a team of environmental sub-consultants assembled for the purpose of providing special expertise in particular areas of concern. • The sub-consulting firms and respective areas of expertise are: o The Endo Company - Air Quality o William Kunzman Associates - Traffic o J.J. Van Houten Associates - Noise o Archaeological Resource Management Corporation - Archaeology In furtherance of obtaining as objective an analysis as possible, efforts were made to solicit public input during the preparation phase of the Draft EIR. This input, in addition to the public review phase required by CEQA, was found helpful to the environmental consultants in presenting the salient concerns of all parties affected by the proposed project. -5- 1.02 PROJECT PROPONENT AND OBJECTIVES • Proponent: City of Huntington Beach, A Municipal Corporation Project information may be obtained by contacting: Mr. Vincent G. Moorhouse, Director Community Services Department 2000 Main Street Huntington Beach, California 92648 (714) 536-5291 In pursuit of the adoption and implementation of the proposed Huntington Central Park Master Plan the City proposes to attain several General Plan goals and objectives which are restated here and included as the objectives of the project: o Goal - To conserve land resources which enhance the physical , social , and economic life-style of the area by maximizing the outdoor and environmental potential of the City by providing com- prehensive, coordinated recreation, parks, and open space programs that fulfill the needs of all segments of the community. (Open Space and Conservation Element, 2.1.2.1-4) o Goal - To achieve wise management and well-planned utilization of t— area's water resources by promoting preservation of the area's marshes and lakes. (O.S./Cons. , 2.1.2.2-3) o Objective - To achieve land use conformity with the General Plan' s designation of "Recreation" use. i o Objective - To protect fragile resources by reliance on ordinance as well as acquisition. (O.S./Cons. , 2.1.2.6-3) o Objective - To maintain existing public recreation areas as per- manent open space lands. (O.S./Cons. , 2.2.2.6-4) o Objective - To expand the existing recreation system to prevent overuse of existing facilities. (O.S./Cons. , 2.1.2.6-5) i In addition to these are certain procedural objectives intended to be acc6mp- lished in sequence as follows: 1. Certification of an Environmental Impact Report on the proposed Hunting- ton Central Park Master Plan. i 2. Adoption of the Huntington Central Park Master Plan. • -6- 3. Acquisition and/or ordinance amendment as required to implement the pro- visions of the Huntington Central Park Master Plan. 4. Project implementation in accordance with the Huntington Central Park Master Plan, Phasing Plan, and upon the availability of funds. 1.03 PROJECT LOCATION AND BOUNDARIES The project is located in the City of Huntington Beach, Orange County, Cali- fornia in the Huntington Central Park and an adjoining area of land desig- nated "Planning Mode" (See Figure 1 and Figure 2). Huntington Central Park is situated at the intersection of Talbert Avenue and Golden West Street and is generally bounded by Slater Avenue on the north; Gothard Street on the east; Ellis Avenue on the south; and Edwards Street on the west. 1.04 PROJECT COMPONENTS The components of the project assessed in this Environmental Impact Report include environmental impacts arising from the implementation of the "Hunt- ington Central Park Master Plan" (Master Plan) and Planning Mode Study. While the act of adopting the Master Plan is clearly one of the discretionary decisions to be made by the City of Huntington Beach, that act alone Will not result in any environmental consequences. Hence, this EIR assesses the secondary impacts arising from implementation of the proposed "Huntington Central Park Master Plan." Implementation of the Master Plan will necessitate: • 1. Acquisition by the City of certain real properties contained within the ultimate boundaries of the Park; 2. Relocation or modification of existing activity areas, and related facilities to accommodate new activities and facilities as proposed in the Master Plan; 3. Site preparation and construction of proposed' facilities to accommodate activities consistent with the Master Plan; and 4. Potential rezoning of certain properties to provide supplemental services to park patrons. The four primary activities described above represent the general requirements in fulfillment of the Master Plan in its entirety. However, there is no attempt here to suggest that the implementation sequence of these activities will necessarily follow the sequence described above. For example, the City may implement an element of the project prior to any future acquisitions, provided that element itself does not require acquisition of real property. • -7- �.

Acquisition (Potential ) The current and potential ultimate boundaries of the Huntington Central Park are illustrated in Figure 3. The three distinguishable boundaries merit fur- ther description as follows: 1. The area designated "Huntington Central Park" comprises a gross area of 297 acres. The City retains ownership of the entire area designated Huntington Central Park. The area designated for expansion contains 30 acres including an unimproved (small lot subdivision) created in approxi- mately 1920, located north of' Ellis Avenue. While the City has purchased many of the lots in this subdivision, several properties still remain under private ownership. The City' s parcel acquisition policies regard- ing Huntington Central Park may result in the City' s ultimate ownership of this area. 2. Additionally, that area designated "Planning Mode," in Figure 3, consists of a gross area comprising 25 acres all under private ownership. The major part of the Planning Mode area (18 acres) is retained by and for the use of Ocean View Mushroom Growers, Inc. Pursuant to the City' s desires to properly plan for the future of the area the Planning Mode area is considered here as an integral part of the Central Park Master Plan due to its close proximity to the Park. To that end, the City has designated this area "Planning Mode" to allow City staff and this EIR to investigate and assess the relative impacts associated with four recrea- tional and non-recreational land use alternatives. In the preparation of this EIR the "Planning Mode Study Area - Special Report" prepared by City staff was utilized as the source in determing potential land use alternatives. That report studied four primary land uses: a. Garden Office/Restaurant. b. Residential in the following densities: 1) Estate residential (3 du/ac) . 2) Low density planned residential (6.24 du/ac) . 3) Medium density (12 du/ac) . C. Recreation Vehicle Park. d. Nursery/Tree Farm. Depending upon the outcome of the City analysis and this EIR the City may choose to: 1) acquire and annex the Planning Mode area to the park; 2) acquire and lease the use of the land; 3) choose not to acquire the Planning Mode area but utilize the City' s zoning authority to guide future use; or 4) do nothing. -10- _ :. � ' r....._. _ _..__......_. i : Q..c. _a _x t� _.....__ ................. . ...........—......... _,. :... _ ....................._ ........................ i n -- �: .�.. 1000 n{ •r......i ._.:__..j. ...-. ._ --............................_ ......:..... : ... . ...

Several existing activities must be relocated or modified to accommodate the uses and/or activity levels contemplated in the Master Plan. They are: 1. Frisbee Golf Course - Now located adjacent to the easterly edge of • Huntington Lae the Frisbee Golf Course is proposed to be relocated or redesigned due to the proposed YMCA facility. 2. Equestrian Facility - An equestrian facility currently operated by a private vendor and located south of Huntington Lake is proposed to be expanded. This facility will extend westerly from Golden West Street • south of Taylor Avenue and will consist of up to 25 acres of land area. Private equestrian activities which presently occur between the present park boundary and Ellis Avenue will be terminated upon development of the new equestrian center. 3. Shooting Ran�e - An existing shooting range facility situated north of • the proposed Fishing Lake (Sully-Miller Lake) is to be enlarged to allow the public to shoot an American Standard Course for handguns with the construction of a two-story structure for additional shooting stations, classrooms, a public restaurant, sporting goods store, and a gunsmith shop. III. Site Preparation and Construction The full scope of new or modified uses to accomplish the principles and objectives of the Central Park Master Plan is described in Table A and illustrated in Figure 5. • 1.05 ENVIRONMENTAL SETTING The project site is situated in a semi -developed urban setting surrounded by low-density residential development, light commercial , industrial , and vacant land uses. Vehicular access to the project area is provided by: North-South Arterials East-West Arterials Edwards Street Slater Avenue • Golden West Street Talbert Avenue Gothard Street Ellis Avenue Located approximately one mile to the southwest of the project site are Bolsa • Bay and Bolsa Chica State Beach. This complex physical and biological estuary which drains to the Pacific Ocean is also the site of numerous oil wells. � -13- Huntington Central Park was initially established for park use in 1969 with the City's purchase of 89 acres of land which was combined with 58 acres containing the landfill previously purchased by the City. This marked the • first of three phases outlined in the original park Master Plan. Amendments to the original Master Plan are now proposed by the City and are assessed in greater detail in this Environmental Impact Report. • 1.06 PROJECT BACKGROUND The Huntington Central Park Master Plan now under consideration represents several years of studies, activities, and public input by City staff, the Community Services Commission, the City Planning Commision, and the City Council . Various interest on the expansion of Huntington Central Park sur- faced during 1979 with the availability of Acquisition and Development Funds through the State Department of Parks and Recreation. Moreover, the City was interested in investigating the long-range potential for revenue produc- ing park uses. In January, 1980 the City reviewed a conceptual park master plan and initi- ated General Plan and zoning amendments to accommodate the ultimate park use. This action was closely followed by the City hiring Harlan Glenn and Associates, a Water Management Consultant to develop plans and specifica- tions to properly manage the lake properties in Central Park. In January, 1981 the City retained the services of Ultrasystems, Inc. which studied the economic feasibility of revenue producing uses within Central Park. The study, completed in May, 1981 investigated five land use consider- ations including existing boundaries up to full expansion to 372 acres. Recom- mended park uses included a hotel and convention facility, an 18-hole golf course, recreational vehicle park, restaurant, snack concessions, YMCA, and an amphithater among other uses. These alternatives were considered and re- viewed by the Community Services Commission at numerous public study sessions. Subsequent to an additional study session and public hearing conducted by the City Council between June and August, 1981 the City Council unanimously re- jected further consideration of a golf course and hotel in Central Park. Support and direction for future uses were placed on an equestrian center, • sports field complex, YMCA, an expanded shooting range, and restaurant uses. Cardoza Dilalo Associates, Inc. , the City' s Landscape Architect prepared the conceptual Master Plan containing such uses. Envista, a division of Willdan Associates was retained by the City in February 1982 to prepare the environ- mental impact report on the master plan consisting of the uses hereinbefore described, the expansion of park boundaries and the considereation of land •, use alternatives in the planning mode area. it -14- • • Table A Central Park Master Plan Recreational and Use Elements Implementation Use Phase Location/Surrounding Uses Description 1.

This discussion will involve an analysis of the following areas: o The environmental setting prior to the initiation of the proposed project; o The impacts associated with improvements necessary to accommodate pro- posed activities at Huntington Central Park; o Measures specifically designed to partially or completely reduce or miti- gate the impacts associated with project implementation; and o Unavoidable adverse impacts where applicable. • 2.01 SOILS AND GEOLOGY • 2.01.1 Environmental Setting The City of Huntington Beach lies toward the northern end of the Peninsular . Range Province. This geomorphic province is characterized by northwesterly- trending mountains and valleys bounded by ancient faults. The City of Hunt- ington Beach is located directly astride the Newport-Inglewood Structural • Zone (see Figures 6 and 7) . The term "Structural Zone" implies that the Newport-Inglewood Fault is not just a single break but consists of many minor faults that cover a certain distance laterally, thus directly affect- ing that area during an earthquake along this system. Figure 8 shows the locations of epicenters from historical earthquakes. • Table B illustrates the approximate. relative distances of the major faults to the project site, historical , and expected future magnitudes for these potentially active fault systems. Available data indicates that, locally, the Bolsa-Fairview Fault traverses the southerly portion of Huntington Central Park (see Figure 9) . Potentially • active traces of this fault slice through Huntington Lake, the Planning Mode Area, and Sully-Miller Lake in a southeasterly direction. Although a detailed soils analysis has not been prepared for the site, indica- tions are that soil stability may be a constraint to potential construction of facilities to accommodate proposed activities in several locations through- out the park.

Figure 11 shows the distribution and thickness of organic soils for Central Park and the surrounding region. A portion of the project site (32 acres) fronting on the south side of Talbert Avenue is a former solid waste landfill dating back to the 1920' s. The most easterly 10 acres of the landfill site is a City-operated landfill under per- mit from the Orange County Solid Waste Enforcement Agency and remains active • for the deposit of solid waste materials. However, that portion of the landfill located between the actual landfill area and Golden West Street has been filled to capacity and terminated as an active landfill . This portion of the landfill site known locally as the Bruce Brother' s Pit was formally closed in June, 1973. -25- • • — -+ ,.ANNI:I f,t-d i (........�_U..�..`...�...`.�,_. _..a?.. ......... _......_�._.___......... ,..

In response to the City's request for comment on the preparation of this EIR, the Department of Health Services submitted initial comments in the form of a letter dated March 1, 1982, (a copy of which is containd in Appendix F) and a final clear- ance letter dated June 7, 1982 (a copy of which is contained in Section 5.02 of this Final EIR) indicating that the most recent inspection of the site and sampling of soils conducted by the Enforcement Section revealed that the Bruce Brothers Pit is not a "potential hazardous waste disposal site.,., However, it is projected that this area will not be suitable for the con- struction of any major structures for approximately 100 years due to soil settlement arising from the decomposition of waste materials. 2.01.2 Environmental Impact Soils and Geology Existing preliminary information indicates potentially severe geotechnical hazards may exist in several locations within Huntington Central Park con- straining the construction of new structures. Additionally, completed land- fill areas in the park may be subject to differential subsidence for a period of up to 100 years. Local seismicity produced from the Newport-Inglewood Structural Zone could re- sult in surface rupture and liquefaction. Potentially active branch faults of the Newport-Inglewood System have been identified within the boundaries of the • project site. The Bolsa-Fairview Fault traverses the southerly portion of the project site in a southeasterly direction (see Figure 9). The location of this fault may impact development of the Planning Mode area. Table C records the expected magnitudes and durations of ground motion associated with earthquake faults for the City of Huntington Beach. The liquefaction potential depends upon many factors in addition to ground- water level such as soil type, relative density and intensity, and duration of ground shaking. Generally, low areas of poorly consolidated recent allu- vium within one mile of the coast are considered to have high liquefaction potentials. 2.01.3 Mitigation Measures Soils and Geology . Prior to the construction of any additional structures and public facilities within Central Park, detailed site-specific soils and geotechnical studies must be undertaken to determine levels of risk and to develop appropriate • -29- Table C ESTIMATED GROUND AND BASE ROCK MOTION CHARACTERISTICS CITY OF HUNTINGTON BEACH Estimated Estimated Predominant Probable Causative Maximum Base Maximum Ground Period of Base Duration of Earthquake Rock Acceleration Acceleration Rock Motion Strong Shaking Fault (g) (g) (Seconds) (Seconds) Newport-Inglewood 0.65+ 1.00 0.30+ 19 0.90 CD Whittier 0.21 0.30 0.30+ 22 Elsinore 0.20 0.35 0.35+ 30 San Jacinto 0.10 0.18 0.45+ 40 San Andreas 0.10 0.20 0.50+ 46 Source: Geotechnical Inputs, Huntington Beach Planning Department. • mitigation measures to reduce seismic and other risks to acceptable levels. • Portions of the site or proposed activities most affected by the prospect of ground movement or potential failure associated with existing conditions and respective mitigation measures are: 1. The restaurant proposed at the southeast corner of Golden West Street and Talbert Avenue is in close proximity to the inactive landfill site. A soils and foundation study should be performed to identify and mitigate any construction issues which may relate to the inactive landfill site (settlement) or seismic hazards. 2. The equestrian center and planning mode are located within a potentially high risk seismic safety corridor with traces of the Bolsa-Fairview Fault. A seismic hazards investigation prepared pursuant to the Alquist- Priolo Special Studies Zone Act should be performed for proposed con- struction located within the affected corridor. 2.02 HYDROLOGY AND WATER QUALITY 2.02.1 Environmental Setting Three significant bodies of water exist within the boundaries of Huntington Central Park--Huntington Lake, Talbert Lake, and Sully-Miller Lake. A majority of surface runoff within the park drains to these three lakes. (See Figure 11A. ) Huntington Lake's drainage area includes the existing equestrian area to the south, areas containing oil wells, developed park land, and other vacant • lands. The watershed and outer edges of the lake contain peaty soils which tend to release dissolved organic compounds which discolor water and reduce its. alkalinity, but generally do not harm aquatic life in the lake. Ground- water seeps into the 13-acre Huntington Lake both above and below the water- line and is particularly evident along the southeasterly shoreline. Historic- ally, Huntington Lake was created from a sand and gravel operation. The Talbert Lake water supply sources consist of storm water runoff and seep- age from the groundwater basin. The lake is generally underlain by fairly heavy clays with intermittent layers of peat and a few pockets of sandier materials. Discoloration of the 25-acre lake has resulted from the peaty soils in the lake's drainage area and bottom, and from runoff from the mushroom plant at Golden West Street and Ellis Avenue. The watershed of Sully-Miller Lake consists of the areas which contain the mushroom growing facility, oil wells, a fire station, an automobile repair facility, the police shooting range, and tributary flows occurring from the Five Points area and portions of residential developments east of Beach Boulevard. The remainder of the 9-acre lake's tributary area is vacant. • -31- ra. r.e-a -..0 . ...........�.I�,�::_.:....`.... _ � .... . _,._,_.,. .............._«.......___._-_......._.....;......................... ._....................................... ...._...._..... .0 .............. __.__-..._._...-.............. 1 1.,..

Sully-Miller Lake is • bounded on all sides by steep banks which tend to be eroded by storm runoff. As with the other lakes, Sully-Miller Lake is also partially supplied by groundwater seeps. Additionally, storm runoff from areas south of Ellis Avenue are fed into the Lake from 33-inch diameter reinforced concrete pipe which passes under Ellis Avenue. Excessive sedimentation has occurred as a result of surface runoff and erosion along the Lake's banks. • 2.02.2 Environmental Impact Each of Central Park 's three lakes is beset by a variety of existing prob- lems and potential problems from project implementation. Following is a • summary of problems inherent to each lake as discussed in previously pre- pared studies for the City of Huntington Beach*: 1. Huntington Lake: Summary of. Problems and Potential Problems a. Bank Erosion - There is excessive bank erosion along certain areas of the shoreline. This erosion adds sediment to the lake, exposes tree roots along the shore, and is aesthetically unattractive. b. Water Level Fluctuation - Annual water level fluctuations of three feet or more can occur due to changes in the groundwater table and • storm runoff. Water level fluctuations of this magnitude are un- desirable. C. Shoreline Slope - The shoreline and near shore slopes are extremely steep in some places. They exceed a 4:1 slope ratio and thus create • a safety problem. • * "Huntington Lake--An Assessment and Restoration Plan," Arlo W. Fast and J. Harlan Glenn and Associates, December 1980.

Nutrient Inputs - Excessive nutrients are entering the lake which ave caused eutrophication which includes: dense algal growth, reduced clarity, oxygen depletion of the deep waters, oxygen super- saturation of surface waters, and the threat of a massive fish kill . The main sources of the nutrient inputs appear to be the equestrian operations on the lake's watershed and the duck population on the lake. e. Water Chemistry - The lake has an unusually high salinity level for a lake in this region. The possible sources of salt contamina- tion include oil well brine, equestrian operation, and irrigation water. f. Groundwater Seeps - There are numerous groundwater seeps along the sTo reline which are unsightly and messy. They also cause bank erosion and inhibit access to the water. g. Debris Inflow - Substantial quantities of horse manure, organic debris, and silt are carried into the lake during high rainfall and runoff. Steps can and should be taken to reduce these inflows. I h. Riparian Vegetation - Willows and other bushes are excessively dense along parts of the shoreline. These plants block access to the water, contribute to the debris load on the lake, are unsightly, and waste water through evapotranspiration. i . Oxygen Concentrations - During the summer there is insufficient oxygen to support fish life at the 2-meter depth and deeper. This forces the fish into a shallow surface zone and removes more than 60 percent of the lake's volume from possible habitation. Further- more, the surface oxygen values are excessively supersaturated. This is a highly unstable condition caused by eutrophication of the lake. The entire lake could easily become oxygen depleted with massive loss of fish life. j. Water Clarity - The transparency or clarity of the water is greatly reduced due—to dense algal populations. k. Fishery - The present fishery appears to be severely impacted by the poor condition of the lake. Even if water quality is improved, the lake has a limited capacity to provide quality fishing unless its natural production capacity is augmented with stocked fish. A stocking program of catchable sized fish could include channel catfish year round and rainbow trout during the winter. 1 . Refuse - There are excessive accumulations of trash and debris in tie lake. Some are man-made while others come from natural sources on the watershed. m. Waterfowl - There is an excessive number of waterfowl on the lake. These excessive nutrient input to the lake, increased trash load, and unsightly conditions along the shore. -34- 2. Sully-Miller Lake: Summary of Problems and Potential Problems a. Bank Erosion - The steep banks above the lake are sparsely vege- tated and consequently subject to excessive erosion. The eroded sediment will ultimately lead to an undesirable filling on the lake. b. Shoreline Erosion - The fluctuating water level and unprotected nature of the shoreline is causing excessive shoreline erosion. The eroded sediments will be carried into deeper water and result in an undesirable shoaling of the lake's maximum water depths. C. Water Level Fluctuation - The lake .is subject to large fluctua- tions in water level . Rapid changes occur due to storm runoff, while longer term changes occur due to changes in the groundwater table. These water level fluctuations are highly undesirable and must be controlled before a shoreline development and refuse con- trol program can be developed. d. Outlet Drain - This drain is presently inoperative. e. Shoreline Sloe - The shoreline and near shore slopes are exces- sive y steep. In many locations the slope exceeds 4:1, and is even vertical in places. This creates a safety problem. f. Nutrient Inputs - Excessive amounts of nutrients are entering the lake. These nutrients cause eutrophication which can include: reduced water clarity, undesirable plant growth, algal mats, oxy- gen depletions, fish kills, odors, insect infestations, and an unsightly appearance. Other evidence of excessive nutrient inputs include high nutrient concentrations in the lake's waters, dense algal populations (green color of water) , oxygen, supersaturation of surface waters, and lack of oxygen below the 5 meter depth during the summer. g. ' Water Chemistry (Quality) - Very high concentrations of salts are entering the lake. Sodium, chloride, and bicarbonate concentrations are especially high. The concentrations of these substances in the lake are still satisfactory but the in-lake conditions could degrade if the influx of these substances are not controlled. h. Riparian Vegetation - Bushes and other plants are excessive along much of the s ore ine. These plants block entry to the water, contribute debris to the lake, are unsightly, and waste water through evapotranspiration. i . Fishery - The natural production capacity of Sully-Miller Lake is inmate to provide quality fishing. Without fishery enhance- ments, the lake will yield the equivalent of only 0.2 to 6.0 suc- cessful fishing trips per day. The lake can support only warm 0 -35- • water fish species on a year-round basis unless special tech- niques are used. The fishery could be severely impacted by the excessive nutrient and other undesirable substances now entering the lake. j. Refuse - Trash accumulation could become a problem after the lake i opened p ne ed to recreation unless provisions are made for a refuse collection system. k. Waterfowl - Excessive numbers of ducks and geese could accumulate at the lake after it is opened to recreation unless a control program is designed and implemented. 1 . Flies and Odors - Undesirable flies and odors presently occur at the lake due to the large piles of horse manure at the mushroom factory. Unless the conditions are controlled, potential for visi- tor usage of the lake will be reduced. 3. Talbert Lake: Summary of Problems and Potential Problems • a. Groundwater Seeps - Talbert Lake has historically experienced detrimental water losses which have been caused by one or more of the following problems: o Pockets or lenses of granular material connecting the exist- ing lake bottom and the groundwater aquifers below the lake. o Pockets or lenses of peat connecting the existing lake bottom and the groundwater aquifers below the lake. o Thin layers of clay soil over granular material or peat. o Low densities in the clay layers of the lake bottom. o Granular material or peat layers in the lakesides that would allow horizontal seepage. o Degradation of the clay layers below the lake bottom by ad- verse chemical reaction with the lake waters. b. Water Chemistry - The lake has an unusually high salinity for a lake in this region. The possible sources of salt contamination included oil well brine and irrigation water. C. Debris Inflow - Substantial amounts of organic debris and silt are carried into the lake during high rainfall and runoff. Steps can and should be taken to reduce these inflows. i -36- d. Water Level Fluctuation - Annual water level fluctuations of three eet or more can occur due to changes in the groundwater table and storm runoff. Water level fluctuations of this magnitude are undesirable. e. Nutrient Inputs - Excessive nutrients are entering the lake. These ave caused eutrophication which includes: dense algal growth, re- duced clarity, oxygen depletion of the deep waters, oxygen super- saturation of surface waters, and the threat of a massive fish kill . f. Water Clarity - The transparency or clarity of the water is greatly reduced uetto dense algal populations and dissolved organic ma- terials as a result of the lake's location in a peat deposit. g. Refuse - There are excessive accumulations of trash and debris in tT—e-I—ake. Some are man-made while others come from natural sources on the watershed. h. Waterfowl - There is an excessive number of waterfowl on the lake. These cause excessive nutrient input to the lake, increased trash load, and unsightly conditions along the shore. 2.02.3 Mitigation Measures The following proposed mitigation measures reflect the recommendations con- tained in the engineering analyses referenced previously which strive to im- prove the water quality, fish habitat, and public appeal of Central Park's lakes as well as mitigation measures proposed to be implemented in conjunc- tion with the project: 1. Huntington Lake: a. Means should be devised and implemented to prevent the inflow of horse manure and other debris from the equestrian area to reduce nutrient runoff into Huntington Lake. The primary source of this inflow is from an existing privately operated equestrian facility. The project proposes an expansion of this facility from 10 acres to 25 acres extending to Golden West Street. The City will retain ownership and direct regulatory control of the expanded facility and thereby impose proper management control responsibilities upon .the leaseholder. b. A permanent lake aeration system is proposed to be installed to: eliminate oxygen depletions in the deep water, prevent excessive algal growth, increase fish habitat availability, increase fish survival and growth, and prevent fish kills. An aeration system should also promote the oxidation of accumulated organic matter in the lake sediments. This should reduce the oxygen demand of the sediments and reduce the nutrient releases from the sediments. -37- C. Huntington Lake should be treated with potassium permanganate and with alum. These should be separate treatments and both should occur after aeration begins. The purpose of the potassium perman- ganate treatment is to help oxidize the organic materials in the water and sediment. The purpose of the alum treatment is to remove suspended materials from the water, reduce the nutrient content of the water, and to form an alum floc on 'the lake bottom and thus help prevent the release of nutrients from the sediments. d. The entire northerly shoreline should be reshaped and reconstructed to provide: 1) better access to the water; 2) a more aesthetically pleasing appearance; 3) a safe slope and underwater configuration, and 4) good erosion control . e. Groundwater seeps occur along the easterly and southeasterly shorelines of Huntington Lake and have created marshy conditions. The marshy problem can be solved by the shoreline stabilization or it can be relieved by the installation of interceptor drains. f. The water level in Huntington Lake should be monitored twice monthly to establish records on lake water levels. g. Unless an adequate fee permit system is inaugurated or suitable funds are otherwise available, the fishery at Huntington Lake should be limited to those warm water fish produced by the lake plus occasional stocks of catchable sized trout and catfish. The continuance of the present fishery, or any improvement in this fishery, is contingent on an improvement in the water quality of the lake. The installation and operation of an aeration system, a reduction in nutrient inputs from the equestrian operations, and a reduction in the waterfowl population will help achieve this improvement. h. Trash and debris can be removed manually by the use of hand tools such as nets and rakes. The material removed should be removed from the park through normal trash collection. The trash and debris could also be removed by the use of mechanical skimmers with screens or baskets operated by pumps. This method also trans- fers water to keep the cove areas from becoming stagnant through decomposition of the soluble organics that are associated with the debris. i . One access pier should be constructed at Huntington Lake. The pier will provide visitor access onto the lake, and access to deep water fishing, in lieu of boat access. The pier should include safety railings, benches, and a special anchoring system which is self adjusting for water level fluctua- tions. =38- j. The proliferation of domestic waterfowl (ducks and geese) should be controlled to minimize quantities of nutrients added to the lake from this source. 2. Sully-Miller Lake: a. The park development plan calls for the terracing and stabilization of large portions of the banks around the lake. Terracing and stabilization are important means of erosion control and should be implemented. In those bank areas where terracing may not occur, such as the banks adjoining the fire department training area and police shooting range, the banks should be stabilized with vegeta- tion cover or by other means. b. The entire shoreline of Sully-Miller Lake should be modified to pro- vide: 1) better access to the water; 2) a more aesthetically pleas- ing appearance; 3) a safe slope and underwater configuration; 4) good erosion control ; and 5) good control of tules and other aquatic nuisances. C. The water level in Sully-Miller Lake should be stabilized. Rapid elevation increases due to storm runoff should be controlled through the installation of a pump and reconstruction of the inoperative outlet drain. Supplemental water sources should be sought for diversion into the lake to prevent excessive reductions in eleva- tion during dry periods. d. Nutrient and other dissolved substance concentrations in the pres- ent runoff water are definitely excessive. The sources of these materials should be more clearly identified, and control measures taken to reduce or eliminate these problems. Storm runoff from the Planning Mode area should be collected and diverted around the 1 ake and i nto the outl et drai n. Thi s i s more desi rable than al 1 owi ng these runoff waters to enter the lake as these waters could contain debris, oil , and other undesirable materials. e. A fishery development plan which is founded on a put-and-take fishery for catchable rainbow trout and channel catfish has been recommended. If the plan is adopted, trout and catfish could be stocked year-round. They would compliment the limited production capacity of Sully-Miller Lake for other fish species. The trout and catfish stocking rates could be adjusted to accommodate or generate any likely level of fishing intensity. f. An important component of the proposed lake development and manage- ment plan for Sully-Miller Lake is lake deepening. Maximum depth presently is about 35 to 40 feet. It has been recommended that the maximum depth be increased to 60 feet in the southern portion of the lake. -39- There are three principal benefits from the deepening: 1) the greater depth will assure the success of the proposed fishery plan for catchable trout and for artificial aeration. It will greatly increase the volume of cold water within the lake, and 2) an in- creased depth will greatly extend the useful life of the lake. Even with the recommended sediment control program the lake will eventually fill with sediment and debris. The recommended deepen- ing could increase the life of the lake by many hundreds of years, and 3) an increased depth will increase the lake's ability to absorb nutrient input without excessive eutrophication. g. It has been recommended that three access piers be constructed at Sully-Miller Lake. These piers will provide visitor access onto the lake and access to deep water fishing. In lieu of boat access the piers are necessary to assure satisfactory fishing success for trout during the summer months. The piers should include safety railings, benches, and a special anchoring system which is self- adjusting for water level fluctuations. h. For long range maintenance of good quality water at Sully-Miller Lake, it is recommended that at least two (2) intake and pump systems be installed. The intake skimmers should be designed to operate with weir boards over the range of water levels recommended. i . The existing shoreline vegetation should be removed and the shore- line should be reshaped and developed. Subsequently, more appro- priate vegetation (trees and bushes) should be planted. These plants should be selected for: low debris characteristics, low water needs, attractiveness, shelter for visitors and animals, and hardiness. They should not be planted too close to the shore- line, nor have root systems which are likely to disrupt the soil cement construction. j. The proliferation of domestic waterfowl (ducks and geese) should be controlled to minimize quantities of nutrients added to the lake from this source. 3. Talbert Lake: a. From a total of six potential methods to prevent groundwater seeps from Talbert Lake, two have been identified as being most feasible for implementation. One alternative, lining the lake with a PVC membrane (plastic) is the easiest method for bidding purposes be- cause it could be let on a square footage basis. The other alter- native identified as feasible consists of lining the entire lake bed with an impermeable layer of clay. b. Means should be devised to control and reduce the inflow of nutri- tive materials such as debris and silt through surface runoff. -40- c. The water level in Talbert Lake should be monitored and stabilized to the greatest extent feasible. Pumping may be necessary to dispose of excessive runoff at times; alternate water supplies may be neccessary during dry periods for water level stabilization. d. The proliferation of domestic waterfowl (ducks and geese) should .be controlled to minimize quantities of nutrients added to the lake from this source. 2.03 BIOLOGY 2.03.1 Environmental Setting Huntington Central Park serves a dual purpose in the midst of one of the world's most heavily urbanized regions. The park not only serves to pro- vide much-needed visual relief and recreational opportunities for the urban population, but at the same time provides refuge for a diverse variety of floral and faunal species. This - is especially true within the "nature area" in the northeasterly portion of the park complex. The nature observation area is considered to be the most significant bio- logical resource within the park because it remains in its natural state with a diversity of indigenous vegetative species which in turn provides a suitable habitat for indigenous avifauna and mammalia. The remainder of the existing s-ite also serves an important function as a habitat for wildlife including the three lakes which have been stocked with game fish. Following is a representative list of the vegetative species which have been observed in Huntington Central park: Trees California Alder (Alnus Rhombifolia) Monterey Cypress (Cupressnus Macrocarpa) Red Gum (Eucalyptus (Amaldulensis) Yate Tree (Eucalyptus Cornuta) Scarlet Flowering Gum (Eucalyptus Ficifolia) Bushy Yate (Eucalyptus (Ehmannii ) Moitch Eucalyptus (Eucalyptus Rudis) Moreton Bay Fig (Ficus Macrophylla) Maidennair Trees (Ginko Biloba) Dawn Redwood (Metasequoia Glyptostroboides) Aleppo Pine (Pinus Halepensis) Monterrey Pine (Pinus Radiata) Torrey Pine (Pinus Torreyana) London Plane Tree (Platanus Aceritolia) California Sycamore (Platanus Racemosa) Weeping willo (Salix Babylonica) California Pepper (Schinus Mol.le) -41- Plants and Shrubs Wild Celery (Apium Graveolens) Wild Radishes (Raphanus Sativus) Sweet Clover (Melilotus Albus) Mustard (Brassica Geniculata) Elderberry (Sambucus Mexicana) Burning Nettles (Urtica Holosericea) Bull Thistles (Cirium Vulgare) Australian Saltbush (Atriplex Semibaccata) Wild Fennel (Foeniculum Vulgare) Narrow Leafed Pondweed (Potamogeton Pectinatus) Bullrush (Scirpus sp. ) Cattail (Typha Latifola) California Gold (Bouganvillea) Crimson Sewel (Bougainvillea) Orange King (Bougainvillea) Ceanothus 9Sierra Blue, Santa Ana, Hurricaine Point) California Redbud 9Cercus Occidentalis) Pampas Grass (Cortaderia Selloana) Parney Cotoneaster 9Cutoneaster Parneyi ) Pride of Madeira (Echium Fastuosum) Southern Fremontia 9Fremontia Mexicana) Toyon (Heteromeles Arbutifolia) Pfitzer Juniper (Juniperus Chinensis) Compact-Pfitzer (Juniperus) Sea Lavender (Limonium Perezii ) Myoporum Insulare, Myoporum Laetum Nerium Oleander (Cherry Ripe, Isle of Capri , Sister Agnes, hardy Red) Pelargonium Domesticum (Mixed Colors) Karo, White Spot, Victorian Box (Pittosporum) Blue Cape Plumbago, Wite Cape Plumbago Cataline Cherry 9Prunus Lyonii ) Lalandi , Santa Crux (Pyracantha) Coates Crimson, Bill Evans (Raphiolepis Indica) Lemonade Berry 9PPhus Integrifolia) Sugar Bush 9Rhus Ovata) Red Flowering Current (Ribes San Quinieum) Pepperment (Mentha Piporita) The above list is by no means an exhaustive inventory of all vegetative spec- ies present, but reflects a compilation of various documents which have been produced in relation to Central Park in the last several years. Similarly, the list of fauna previously observed in the park follows: Pocket Gophers (Thomomys Bottae) Western Gulls (Larus) Sandpipers (Charadrii ) Black-Necked Stilts (Himantopus) Meadowlarks (Sturnella Neglecta) Common Crow (Corvus Brachyrhynchos) -42- • Jackrabbits (Sylvilagus Bachmani ) • California Mouse (Peromyscus Californicus) Ducks (Aythya Collaris) Geese (Anatidae) Coots (Fulica Americana) Western Fence Lizard (Sceloporus Occidentalis) Pheasants (Phaaianus) • Blue Gill (Lepomis Machrochirus) Brown Bullheads (Letalarus) Goldfish (Carassis Auratus) Threadfin Shad (Polynemidae Alosa) Redear Sunfish (Lepomis Microlophus Salmoides) Largemouth Bass (Micropterus Salmoides) Channel Catfish (Ostariophysi ) 2.03.2 Environmental Impact In its current state, Huntington Central Park comprises an extremely viable habitat for flora and fauna which impacts the surrounding vicinity and the City of Huntington Beach as a whole in a positive manner by providing a refuge for wildlife and vegetation and by providing open space values and recreational opportunities for residents. Upon further improvement and expansion of the facility, beneficial community impacts will expand along with the park as further open spaces and planted areas will be introduced. • Development of the ballfield complex will impact existing landscaped areas. The westerly edge of the proposed ballfield complex will compete with existing landscaped areas resulting in the loss of 35 to 75 trees. The severest effect result from the northwesterly most sports field which will result in the loss of approximately 35 pines, eucalyptus and sycamore trees ranging in height • from 20 to 40 feet. This sports field will also result in the loss of numerous smaller trees which were planted throughout this site. However, these trees were not considered as significant in size and stature and therefore not considered as important as the larger trees, mentioned. • 2.03.3 Mitigation Measures Given the tree impact as reported above the City proposes to supplement the buffer area with additional trees and mounding to mmitigate the noticeable effect upon existing landscaping. Additionally, the City should transplant as many trees as possible taking advantage of their larger size. • • • -43- 2.04 LAND USE AND PLANNING CONSIDERATIONS 2.04.1 Environmental Setting Huntington Central Park currently exists as a partially developed complex which is generally devoted to recreational uses including such uses as the library, nature observation areas, the midden area, a system of trails and picnicking areas, equestrian trails, a frisbee golf course, the adventure playground, the shooting range, and a youth camping area. Surrounding land uses include residential development to the north and northwest; the proposed Bolsa Chica linear park to the west; various land uses including the Orange County Transfer Station, residential and industrial development to the east; and oil fields and stables to the south. Zoning in the vicinity includes R-1 (Single-Family Residential ) to the north and west; primarily M-1 (Light Industrial ) to the east; and RA (Residential Agricultural ) to the south. Zoning designations within existing and proposed park boundaries include CF-R (Community Facilities-Recreational ) , RA (Resi- dential Agricultural ), and M-1 (Light Industrial ) for the City Yard and the shooting range. The Huntington Beach General Plan currently designates the site and vicinity as Public Use/Open space. 2.04.2 Environmental Impacts i 1. Land Use and Planning The entirety of the existing Central Park area (297 acres) and the 30- acre area proposed to be annexed to the Huntington Central Park (Figure 3) are designated "Recreational " in the City's General Plan-Open Space/ Conservation Element. In addition, the entire project area (existing park, proposed park expansion area, and planning mode) are designated "Public Use-Open space" in the City's Land Use Plan. In the event the City chooses one of the nonrecreational/open space options for the Plan- ning Mode Area the General Plan would have to be amended to a land use designation consistent with the desired ultimate land use. 2. Land Use Compatibility (External ) Proposed additions and modifications to Huntington Central Park will alter, in varying degrees, the relationship of park activities to nearby and adjoining land uses. Taking into account the types of facilities proposed, existing park boundaries and park uses, and existing or ulti- mate land uses surrounding the park, potentially significant land use conflicts arise. Conflicts with land uses outside of Central Park are limited to those occurring as a result of the interrelationship of the proposed ball field complex and the residential neighborhood located -44- • approximately 550 feet to the west. Residents of this neighborhood could be impacted by light and glare from the 46 light poles proposed for field illumination which may range in height from 60 to 80 feet. A diagrammatical depiction of the spatial relationship of the ball fields and the nearest residences is shown in Figure 12 which illustrates that measures will be necessary to prevent light from travelling off-site where existing residences may be affected. A total of 46 light poles (each containing 8 fixtures with 1,000 to 1,500 watt lights) ranging in height from 60 to 80 feet are proposed for the ball field complex and an undetermined number of lights will be required to light parking lots and provide security lighting for buildings con- structed. The parking lot and building security lights will not signifi- cantly impact existing residential uses, but proper directional design will be necessary to prevent adverse impacts from the 2,200-car parking lot on potential residential development on the Planning Mode property. The lighting proposed for the ball fields, however, could potentially have adverse impacts in the form of light and glare on residences to the • west and on wildlife in the existing nature area. Figure 12 serves to demonstrate that if lighting is not confined to the ball field area it could directly affect nearby residences because existing and proposed buffering is probably not tall enough to, block the projected light. Thus, special care will be required to ensure that the lighting system is designed with hooding devices to confine light to the actual site • intended for illumination. 3. Land Use Compatibility (Internal ) Potential conflicts arising from the proposed uses are generally insig- nificant with the exceptions of: 1) the ball field complex which abuts the existing nature area; and 2) the location of the 2,200-space parking lot relative to the recreational facilities and uses it serves. The ball field complex is located directly south of, and adjacent to, the existing nature area. The active and occassionally loud character- istics associated with use of the ball fields is inherently incompatible with the passive and more subdued environment of the nature area. Moreover, nighttime use of the ball field complex accomplished with ball field illumination will further affect the wildlife. While the immediate effect upon the nature area might include the loss of some wildlife inhabitants such loss is considered temporary. This is evi- denced by the fact that wildlife has thrived in .the nature area in the presence of street lighting and traffic noise on Golden West Street. The 2,200-space parking lot facilitiy is located such that access to most recreational activities, the library, and other uses requires pedestrian crosswalks across Golden West Street and Talbert Avenue. The land use concern raised by this relationship is that of pedestrian safety and is discussed in greater detail in Section 2.06 - Traffic and Circulation. • -45- • Lj l...J x. , �• .._Jk.--..

Planning Mode • a. Garden Offices/Restaurant - Although generally regarded as a low intensity use, garden offices with a 35-foot height limit may pose land use compatibility problems with adjacent park uses and future estate residential development. Through landscaping and proper design, a garden office complex could be visually integrated into the largely low intensive land uses surrounding the planning mode site. However, this alternative is projected to generate the highest traffic volume of any of the land uses considered for the planning mode. The inherent increase in traffic generation and related noise may detract from the rural , equestrian-oriented atmosphere of Central Park and planned estate residential devlopment to the south. Development of garden offices with an adjoining restaurant would require a General Plan amendment redesignating the planning mode property from open space to a commercial designation and a zone change. An appropriate zoning district would be R-5, office professional . b. Residential - Estate residential development on the 25-acre planning mode site would allow for development of up to 71 homes (3 du/ac) , according to the projected density for the Ellis-Goldenwest Specific Plan area (a proposed residential development located south of the . planning mode area) . Similar development on the planning mode property would serve as a natural extension of the specific plan area, ensuring land use compatibility with adjacent residential and park uses. This type of development could also serve to enhance the Ellis-Goldenwest area by preserving the continuity of low intensive, equestrian- oriented development established by Central Park and planned eques- trian estates to the south. A low density planned residential development of 148 units (6.24 du/ac) , properly landscaped and buffered, would present no land use compatibility concerns with any of the surrounding uses and would enable the builder to bring the purchase price of individual units in line with a wider range of incomes. A medium density development of 285 units (12 du/ac) would accomplish the same goal but could pose incompatibility problems with the largely low intensive uses r surrounding the site. Relatively low traffic generation projections (see Section 2.4) for all three residential densities would not significantly impact the area's rural atmosphere. Residential development on the planning mode site would require a General Plan amendment redesignating the property from open space • to residential . Appropriate zoning for a low or medium density residential development would be R1-PD and R2-PD, respectively. • -47- Estate development would likely be implemented as an extension of the Ellis-Goldenwest Specific Plan. C. Recreation Vehicle Park - The 25-acre planning mode property, used or a recreational vehicle camping park, could allow for approxi- mately 580 campsites. Conceptual plans show the property terraced down to the shore of Sully Miller Lake, which would be landscaped and offer recreational fishing opportunities. Terracing of the RV park development to the lakeshore would help to visually integrate this land use with surrounding recreational uses in Cerntal Park. Should this alternative be selected for the site, plans are to landscape and rennovate Sully Miller Lake which would serve not only as an attraction for campers but would also create a new recreational and fishing area for City residents. An RV park facility located on the planning mode property may, however, negatively impact the planned estate residential develop- ment south of Ellis Avenue. If adequate setbacks, berms, landscap- ing, or other buffering techniques are incorporated into the overall design, recreational uses of this type could be developed without any significant adverse impacts. The low traffic volume generated by this use would not adversely impact the area's circulation system. Traffic noise (and vehicle emissions) would also be relatively insignificant and would be compatible with the area' s rural nature. The planning mode property, developed as an R.V. facility, would require a zone change to either ROS (Recreational Open Space) or CF- R (Recreational - Community Facilities) . d. Nurser /Tree Farm - The final land use analyzed for the planning mode site is a commercial nursery combined with a tree farm. A hypothetical development which projects that approximately one third (eight acres) of the site woudl be utilized as a commercial nursery consisting primarily of open space for plant distribution, a small sales office and greenhouses. The wholesale tree farm area would comprise the remaining 16 acres. Whether the trees are grown on site or stored in containers, no permanent structures would be necessary in the tree farm area. This alternative would likely serve as a transitional land use. If properly designed, a nursery/tree farm would blend well with the surrounding park and the planned estate residential development to the south. Trees and other plant life associated with this land use would accent the park's own vegetation and highlight the rural quality of the estate development. Also, the relatively low traffic volume generated and the passive nature of this use preclude any appreciable rise in air pollutant or noise levels. This combined -48- use is consistent with the present open space development designa- tion and zoning on the site with the exception of the 1.89 acre northeast corner of Ellis Avenue and Goldenwest Street zoned MI-CD. 2.04.3 Mitigation Measures 1. Ballfield Complex Lighting a. Minimize the height of all light standards especially those located on bal.lfields closest to residential neighborhoods. The maximum height of such standards (and lighting fixtures) should be no more than necessary to achieve the appropriate level of lighting for nighttime use. b. Light fixtures oriented in any manner which would result in off- site glare should be hooded, screened, or modified by appropriatte means at the light source to eliminate glare. C. Use of lighting fixtures should be limited to City-authorized play and should be programmed by automatic means (or controlled by the City) to turn-off no later than 15-minutes after the City-approved time for nighttime play expires. d. The landscaped buffer proposed west of the ballfield complex shall be properly maintained so as to adequately screen the lighted facilities from nearby residential uses. e. The design and development of a lighting plan for the ballfields shall be subject to the review of a lighting engineer to determine 1 conformance with these mitigation measures and others required by the City. 2. Ballfield Complex Noise i Noise impacts and mitigation measures associates with the project are discussed in greater detail in Section 2.08 of this EIR. 2.05 ARCHAEOLOGICAL AND HISTORICAL RESOURCES 2.05.1 Environmental Setting A resources assessment which is the basis for the ensuing discussion was conducted on the existing Huntington Central Park, the Planning Mode area, and the proposed park expansion area by Archaeological Resource Management Corporation. The purpose of the assessment was to delineate any resources which could be impacted through modification of the land for park use. i -49- 1. Archaeological Resources (Prehistoric) Two prehistoric sites have been located within the park's boundaries: Ca-Ora-142 and the northeastern portion of Ca-Ora-82. Ca-Ora-142 is located on a knoll directly northwest of the intersection of Talbert Street and Golden West Street. Ca-Ora-82 is located along the bluff edge between Ellis Avenue and Taylor Drive with Edwards Street bisecting the site (see Figure 13) . Ca-Ora-142 was field checked by Archaeological Research, Incorporated (ARI) in 1972. According to the survey report, the Division of Highways used the site area as a borrow site, thus, almost totally removing the deposit (ARI 1973: 19). According to the updated site form, only one edge of the midden remains with scattered shell and flakes the only surface indicators as to the prior location of the site. The northeastern portion of Ca-Ora-82 extends into the project area. This portion was excavated by the Pacific Coast Archaeological Society (PCAS) under the direction of Lee Savio (Brown) with the aid of the field classes from Saddleback Community College and Santa Ana Community College. The project was started because the widening of Edwards Street followed by heavy rains resulted in considerable erosion along the road right-of-way which exposed numerous artifacts and human skeletal mater- ial . The primary purpose of the excavations was an attempt to preserve, through controlled excavations, that area of the site which appeared to be in danger of being destroyed through natural forces aggravated by i the road widening. Thirty-seven 2m2 units were excavated in the area of the site contiguous to the road and east of the road. In all , eight (and possibly nine) burials were salvaged. In addition, an extensive pH testing and mapping project was completed by John Maguire and Ed Lyons of PCAS which defined the perimeters of the site. S i The excavations which have been completed on the portion of CA-Ora-82 within the park boundaries are sufficient to define this area as a pre- historical burial ground. Although the limits of the burial ground with- in the site area have not been defined, those portions of the site which functioned as living areas are also important to future research into the life style of the prehistoric peoples who inhabited the area. The site has been radio-carbon dated to approximately 3000 B.C. and, consequently, can provide valuable data pertinent to research geared toward the earlier occupations of the Huntington Beach Mesa Area. 2. Paleontological Resources According to the ARI report (1973) , no known paleontological locations are within the park limits. However, since the park is located on the Huntington Beach Mesa, it is possible that vertebrate faunal materials related to the Pleistocene epoch could be uncovered. i -50- . uu /J 00 1 100Q, - ►. \ el I II .;/w - - • ♦1 a • Tan min U MP to° }.

Archaeological Resources (Prehistoric) The archaeological potential for Ca-Ora-142 is low due to the fact that a major portion of the site no longer exists. Some undisturbed portions which are covered by bulldozer backfi11 , however, may still remain intact and could be encountered during earth-moving activities. On the other hand, Ca-Ora-82 represents a significant archaeological find which warrants protection and preservation. • Because this area has been well defined, it has become an easy target for pot-hunters. During a field reconnaissance by Frank Chapel in 1979, numerous fresh holes were observed in the site area. It is assumed that the area continues to be dug by unauthorized persons for unscientific purposes. Development of active uses on and near Ca-Ora-82 is undesirable due to the significance and fragile nature of the site and associated artifacts. 2. Paleontological Resources • Although no records of any significant paleontoligical deposits within Central Park or the proposed expansion areas exist, earth-moving opera- tions which excavate over five (5) feet in depth have a potential for uncovering such resources. • 2.05.3 Mitigation Measures 1. Archaeological Resources (Prehistoric) As previously discussed, some portions of Ca-Ora-142 may remain intact • and could be uncovered during earth-moving activities. If such deposits are encountered during earth moving activities, the activities should be diverted and a qualified archaeologist should be retained to determine the significance of any remaining midden deposit. In respect to Ca-Ora-82, it is recommended that the portion within the park area be fenced to discourage pot-hunters and their destructive efforts. Preservation would also include excluding the area from con- struction of irrigation pipes, equestrian trails, sidewalks, and other structures. It is also recommended that any improvements to, or along Edwards Street, be monitored by a qualified archaeologist. • -52- f 2. Paleontological Resources It was noted by ARI (1973:8) that earth moving activities which excavated over five feet of dirt (in depth) had the greatest potential for uncover- ing paleontological deposits. In the event that such deposits are uncovered, a qualified paleontologist should be retained to inspect the deposit and remove significant fossils. 2.06 TRAFFIC AND CIRCULATION 2.06.1 Environmental Setting The following discussion is a capsulization of the "Central Park Traffic Study" prepared by William Kunzman Associates and March 24, 1982. The traf- fic study is contained in its entirety in Appendix B. Local and regional access is provided for Central Park from the following roadways: 1. Golden West Street Golden West is an existing north/south roadway in the City of Huntington Beach which divides the Central Park site and is presently striped as a four-lane undivided roadway. Portions of Golden West are constructed to the full ultimate primary roadway cross section with curbs, gutters and street lights, but adjacent to the site, Golden West is currently con- structed with only graded shoulders and has no center median as it traverses the site. Golden West has an existing on-street bicycle route adjacent to the site and is also an existing O.C.T.D. Bus Route. 2. Talbert Avenue Talbert Avenue is an existing two-lane undivided roadway which divides proposed park uses from Golden West eastward. As it is shown on the City's Circulation Plan of Streets and Highways, Talbert is designated to be ultimately constructed to secondary roadway standards between Golden West and Gothard and primary roadway standards east of Gothard. In addition, a discontinuous portion of Talbert Avenue is constructed west of Edwards but it does not align directly with Talbert to the east of Golden West. The two sections of Talbert are not shown as connecting in the City's Circulation Plan even though the Orange County Master Plan of Arterial Highways shows Talbert Avenue as a continuous arterial between Edwards and Golden West Street. i -53- • 3. Ellis Avenue Ellis Avenue is an existing east/west roadway located along the southern boundary of the project site. Ellis is presently constructed as a two- lane roadway with graded shoulders between Edwards and Gothard. Ellis is designated to be ultimately constructed to primary roadway standards between Gothard and Edwards and is shown as a proposed primary arterial • connecting to Bolsa Chica to the west of Edwards. Existing Traffic Volumes The most recent daily traffic volume counts for roadways in the study • area are shown in Table D. Traffic volume counts were obtained from the City of Huntington Beach, the County of Orange, and CalTrans. Traf- fic volumes on State Highways are 1980 traffic volumes, City of Hunting- ton Beach average daily traffic volumes are for 1978 conditions, and County of Orange Traffic Flow volumes are dated for 1981 conditions. Existing Daily Volume to Capacity Ratios Roadway capacity is generally defined as the number of vehicles which can reasonably be expected to pass over a given section of a road in a given time period. Daily roadway capacities reflect estimates of the amount of daily traffic which will result in peak hour traffic volumes equal to the maximum desirable capacity for each roadway type. Daily roadway capacities for Level of Service D conditions on roadways in the study are estimated to be 12,500 vehicles per day for two-lane undivided roadways,. 22,000 vehicles per day for four-lane undivided roadways, 33,000 vehicles per day for four-lane divided roadways, and 49,500 vehicles per day for six-lane divided roadways. It should be noted that the daily capacities estimated are lower than can actually be achieved by approximately ten percent. This is also reflected in the Level of Service D notation which is typically used as the design stand- ard for urban conditions. • By dividing existing traffic volumes by daily roadway capacity for existing facilities, existing daily volume to capacity ratios have been calculated and are shown in Figure 4 of the Traffic Study (Appendix B) which indicates that Golden West between Talbert and Slater is currently approaching capacity for the existing roadway geometrics adjacent to the project site. • • -54- Table D TRIP GENERATION Daily Daily Weekend Weekend Generation Trips Generation Daily Trips Land Use Quantity Rate Generated Rate Generated Central Park Project Ballfield Ccmplex 6 fields 70/Diamd 420 100/Diamd 600 Equestrian Center 100/Units 100 300/Unit 300 Shooting Range 6 AC 77/AC 463 128/AC 768 Restaurant Complex 2 Units 2,100/Unit 4,200 3,150/Unit 6,300 YMCA 5.5 AC 90/AC 495 110/AC 605 Subtotal 5,680 8,580 Planning Mode Alternatives 1.

First, the traffic which will be generated by future development is determined. Secondly, the traffic volumes are geographically distributed to major attractions of trips such as employ- ment centers, commercial developments, and residential developments. Finally, • the trips are assigned to specific roadways and the future traffic volumes are determined on a route-by-route basis. Table D portrays the number of vehicular trips projected for the proposed land uses within Huntington Central Park. Depending on which land use alter- native is selected for the Planning Mode area 6,210 and 10,950 trips are ex- pected to be generated. Traffic generated from the Planning Mode varies between 460 and 4,800 vehicular trips per day depending on land use. Existing Plus Project Traffic Conditions Once the project-related traffic is assigned to the existing street net- work and added to existing volumes, the traffic impact can be assessed. An analysis of existing plus project-related traffic indicates that, based on current conditions, the roadways serving Central Park can accom- modate the additional generated traffic. Golden West Street would be operating slightly beyond capacity and will require improvement to its ultimate cross section as a four-lane divided roadway in conjunction with park development— Other surrounding roadways are capable of accom- modating additional generated traffic at the present time. In respect to signal warrants, a signal at the intersection of Golden West Street and Talbert Avenue has been constructed. • Future Traffic Considerations Existing and average daily traffic volumes for future 1995 conditions with or without the proposed project, are shown in Table E. The 1995 • daily traffic volumes are from the City of Huntington Beach Traffic Model which was run and tested by the County of Orange EMA in the Winter of 19.81. EMA staff indicated that the land uses assumed are for the existing General Plan of the City of Huntington Beach. Future 1995 average daily traffic volumes shown in Table E have been • identified by EMA staff as reflecting the existing General Plan for the City of Huntington Beach. However, as coding for individual zones in such traffic models represents an aggregate of land use in a particular zone, and is typically tabulated in terms of employees, the specific land use assumptions for the Central Park project area and the Planning Mode study area could not be identified. To provide for a worst case analysis, it has been assumed that neither the proposed Central Park • project, nor land use alternatives for the Planning Mode study area have • -56- Table E EXISTING AND PROJECTED DAILY TRAFFIC VOLUMES Current 1995 Average 1995 With Project* Daily Without (Volume to Volume Project Capacity Ratio) EDWARDS STREET Between Warnerand Slater 8,000 15,000 15,000 (0.68) Between Slater and Talbert 6,000 91000 9,000 (0.41) Between Talbert and Ellis 5,000 6,000 6,000 (0.27) GOLDEN WEST STREET Between Warner and Slater 27,000 35,000 38,000 (1.15) Between Slater and Talbert 21,000 32,000 36,000 (1.09) Between Talbert and Ellis 17,000 29,000 33,000 (1.00) GOTHARD STREET Between Warner and Slater 6,000 13,000 13,000 (0.59) Between Slater and Talbert 5,000 13,000 13,000 (0.59) Between Talbert and Ellis 5,000 13,000 13,000 (0.59) BEACH BOULEVARD Between Warner and Slater 46,000 66,000 67,000 (1.35) Between Slater and Talbert 39,000 65,000 66,000 (1.33) Between Talbert and Ellis 40,000 60,000 60,000 (1.21) WARNER AVENUE I Between Edwards and Golden West 24,000 50,000 51,000 (1.03) Between Golden West and Gothard 25,000 52,000 53,000 (1.07) Between Gothard and Beach 25,000 53,000 54,000 (1.09) SLATER AVENUE Between Edwards and Golden West 10,000 11,000 13,000 (0.59) Between Golden West and Gothard 91000 10,000 11,000 (0.50) Between Gothard and Beach 8,000 10,000 10,000 (0.45) TALBERT AVENUE West of-Edwards 2,000 4,000 Not Available Between Golden West and Gothard 4,000 6,000 9,000 (0.41) Between Gothard and Beach 4,000 10,000 12,000 (0.36) ELLIS AVENUE Between Edwards and Golden West 11000 6,000 7,000 (0.21) Between Golden West and Gothard 1,000 7,000 8,000 (0.24) Between Gothard and Beach 11000 10,000 11,000 (0.50) * Includes "Worst Case" Situation for Planning Mode i Source: William Kunzman and Associates, 1982 -57- • been included in future 1995 traffic model volume projections. Based on • this assumption, traffic from the Central Park project and the Planning Mode study area have been added to 1995 traffic model projections. the Planning Mode study area, Golden West between Talbert and Ellis will also operate at capacity. Based on future volume to capacity ratios, Beach, Warner, and Golden • West north of Talbert are projected to exceed capacity with the proposed Central Park project. With the addition of the worst case traffic from the Planning Mode study area, Golden West between Talbert and Ellis will also operate at capacity. Although conclusions are based on worst case assumptions and are without the specific knowledge of all land use assumptions in the traffic model for particular traffic zones, general traffic model results indicate that it is preferable that land uses which are primarily .local in nature, such as the proposed Central Park project, will result in less overall traffic impacts than will uses generating regional type trips such as the garden office project on the Planning Mode site. • Other Traffic Considerations o Vehicle Parking Demand - Vehicle parking demand for each of the proposed parking lots has been estimated. Parking demand estimates • are based on parking demand studies performed by Kunzman Associ- ates, a review of existing parking codes, and a literature search of parking demand at inventoried park facilities. Based on the estimated parking demand, the proposed number of parking spaces is anticipated to be adequate for future traffic conditions. o Golden West Parking Area Access - Four driveway locations are pro- posed or the 2,200-vehicle parking lot. Based on a review of park locations, a maximum of 75 percent of accumulated parking demand was observed to egress a site during a peak one-hour period. Based on the distribution of traffic from the site, all driveways from the site are anticipated to be capable of adequately servicing • peak period egress demand. Some short-term queuing at the Golden West and Talbert intersection may occur; however, the intersection should be capable of servicing vehicles with a minimum of vehicle delay to egressing traffic and traffic on the arterials. o Pedestrian Access - With the proposed location of the Golden West • parking lot, pedestrians will be required to cross Golden West for access to the ball field complex and other portions of the park. Pedestrians will also be required to cross Talbert Avenue for access to the existing library and the existing portion of the park. Pedestrian crossing facilities should be located to create crossings of major streets at signalized intersection locations. • • -58- Pedestrian crossing indicators should be installed in conjunction with the installation of the traffic signal at Golden West and Talbert and pedestrian walkways should be oriented to provide for pedestrian crossings at this location. Due to the remote location of proposed parking to the ball field complex, it is of concern that some ball field users will attempt to park on Golden West or will stop adjacent to the ball field complex to load and unload passengers. City roadway standards do not provide for on-street parking on arterials, and the stopping of vehicles to load and unload passengers is anticipated to result in a significant safety hazard and create congestion on Golden West. "No Stopping" signs should be posted on Golden West adjacent to the ball field complex to eliminate the loading and unloading of passengers from vehicles on Golden West and ball field users attempting to park on Golden West. o Emergency Vehicle Access - For existing and proposed portions of Central Park, the park s designed with only remote parking loca- tions and vehicle access is not permitted interior to the park. To provide for emergency and maintenance vehicles access interior to the park, pedestrian trails should be constructed as all weather surface trails and be of sufficient width to accommodate emergency and maintenance vehicles. Trail access locations should be con- trolled with locked barriers to restrict private vehicles from driving on these trails in the parks interior. o Equestrian Crossings - With the provision of an equestrian facility in the park pan, there is the potential for equestrian users to attempt to travel along and across adjacent arterials. To provide for the maximum safety of the horses, the riders, and the driving public, it is highly desirable for equestrian trails to be identi- fied which are internal to the park area and do not require any at- grade crossings of the adjacent arterials. In any event, the at- grade crossing of arterials should be minimized and should only occur at prescribed locations where adequate visibility is feasible and lower traffic volumes exist. Equestrian crossing locations should be posted to alert motorists and the locations should be monitored by the City of Huntington Beach to insure crossing safety. o Potential Future Realignment of Ellis to Connect With Talbert - Dur- ing the planning process, the realignment of Ellis Avenue west of Golden West to connect with existing Talbert west of Edwards has been proposed. The proposed realignment would divide existing park properties and result in an isolated site south of the re- aligned Ellis Avenue. The proposed realignment is anticipated to result in increased pedestrian and equestrian crossings for site access. Special treatment of parking for the isolated site would probably need to be considered. In addition, the realignment would significantly reduce the extent to which equestrian trails -59- • could be provided which would not cross arterial highways. The proposed realignment is not shown on the existing City of Hunting- ton Beach Circulation Plan and would require the modification of that plan. In addition to the Ellis-Talbert connection there exists the poten- tial feasibility of connecting the discontinuous segments of Talbert Avenue via an alignment south of the Lake. This connection, along • with the Talbert bridge crossing the Santa Ana River, would provide through travel for east/west traffic. While this alternative is consistent with the County Master Plan of Arterial Highways it would require further consideration for its inclusion in the City's Circulation Element. • One of the contributing factors to the capacity problems and pro- jected heavy volume on Warner Avenue is the lack of adequate and continuous parallel' facilities serving destinations to the east. o Vehicle Miles of Travel - Based on information derived from the Los Angeles Regional Transportation Study (LARTS) , average one-way trip • ends by land use have been identified and are shown in Table F. Based on the average daily trips generated by the Central Park Project and Planning Mode study area alternatives, the vehicle miles of travel for the proposed uses have been calculated and are shown in Table G. • 2.06.3 Mitigation Measures The following mitigation measures are recommended to minimize traffic impacts associated with the proposed project and maximize public safety: • 1. Maintain the traffic signal at Golden West Street and Talbert Avenue to provide for safe pedestrian crossings of Golden West from proposed parking facilities. 2. Improve Golden West Street as a four-lane divided roadway between Talbert and Slater in conjunction with development. • 3. Construct all streets bordering the project to half-section widths adja- cent to the project boundary in conjunction with development. 4. Design bicycle and pedestrian circulation facilities to create crossings of major streets at signalized intersection locations. • 5. Construct pedestrian trails internal to the park system with all weather surfaces and of sufficient width to accommodate emergency vehicle ac- cess internal to the park area. Trail access locations should be controlled with locked barriers to restrict non-emergency/maintenance vehicle access to interior park locations. • • -60- 6. "No Stopping" signs should be posted on Golden West adjacent to the ball field complex to eliminate the loading and unloading of passengers from vehicles on Golden West and ball field users attempting to park on Golden West. 7. Future potential equestrian crossing locations of arterials should be minimized and crossing locations should be posted and monitored by the City to insure crossing safety. 8. Prior to the approval of detailed engineering plans for the ultimate de- velopment of Golden West Street, the City of Huntington Beach should incorporate appropriate input from the Orange County Transit District as to the location and design of bus facilities. 9. To relieve queuing problems during peak hours and special events at the park, the City should consider a southbound right-turn-only lane on Golden West at the park entrance. 10. To accommodate the loading and unloading of passengers at the ballfield complex and avoid on-street congestion therefrom, the City should con- sider either an inlet street or a loading and unloading zone safely separated from traffic on Golden West Street. 11. The City should consider improving Talbert Avenue to its ultimate design standard in conjunction with park improvements.

Climate and Meteorology • The study area has a mediterranean climate with warm summers and mild winters. The average daily temperature during the winter months is 52 degrees. During the summer months, temperatures average 68 degrees. Medium humidity and daily fogs are also characteristic of this shoreline. The land/sea breeze is the primary factor affecting the region's mild climate. The daytime winds are sea breezes predominantly from the south- west which flow at 5 to 7 -miles per hour. During the night the winds usually reverse direction. These land breezes flow from the northeast at 1 to 2 miles per hour. During the fall and winter months the study area is subject to moderate and strong Santa Ana winds. The average precipitation is approximately 12 inches annually within the project vicinity. Rain falls in Orange County an average of 35 days per year. • -62- 2. Ambient Air Quality The South Coast Air Quality Management District (SCAQMD) maintains ambient air quality monitoring stations at numerous locations, the closest of which are Los Alamitos and Costa Mesa. Ambient air quality data from these stations is given in terms of state standards which were adopted to protect public health with a margin of safety. In addition, California has adopted episode criteria for oxidant, carbon monoxide, and sulfur dioxide. Episode criteria represent short-term exposures at concentrations which actually threaten public health. Air quality trends have developed at the Costa Mesa and Los Alamitos air quality monitoring stations between 1978 and 1980. These trends are discussed below. Appendix D of this report provides the ambient air quality data in terms of state standards. Also included is a comparison of State standards and emergency criteria. From this information it can be seen that only sulfur dioxide has not equalled or exceeded the relevant 1-hour and 24-hour State standards. All other major pollutants monitored have exceeded the standards at the two nearby stations. Of all the pollutants, total suspended particulates equal or exceed the California standard most often. Suspended particulates exceeded the California 24-hour standard of 100 micrograms per cubic meter on 46 percent and 30 percent of the days monitored at the Los Alamitos and Costa Mesa stations, respectively. Between 1978 and 1980, 19 percent of the months at the Costa Mesa station exceeded the lead standard (1.5 micrograms per cubic meter over a 30-day averaging time). The lead standard was exceeded at Los Alamitos during 22 percent of the months. However, due to the phasing out of lead as a motor vehicle fuel addi- tive, this condition is expected to improve. Oxidants are also of concern. The California one-hour standard (0.10 pm) was equalled or exceeded on 16 percent of the days monitored at Los Alamitos and 9 percent of the days monitored at Costa Mesa. Ten Stage One episodes for ozone were called between 1978 and 1980 at the Los Alamitos monitoring station. Five were called in 1978, 2 in 1979 and 3 in 1980. No Stage Two episodes have been called at Los Alamitos. Four Stage One episodes, but no Stage Two episodes for ozone were called between 1978 and 1980 at the Costa Mesa monitoring station. Three Stage One episodes were called in 1978 and one in 1979. At Costa Mesa, the State standard for carbon monoxide (10 ppm - 12-hour avg.) was violated on ten days, during the last three years, but the one- hour standard was not exceeded. Carbon monoxide levels in Los Alamitos were not measured. Carbon monoxide episode levels have not been attained at either station. Although nitrogen dioxide was not measured at Los Alamitos it did exceed the one-hour standard on 1 percent of the days monitored at Costa Mesa. The California standard for nitrogen dioxide is .25 ppm for one hour. -63- 3. Effects of Pollutants on Receptors Demonstrated effects of air contaminants on health and vegetation are briefly discussed below. Oxidants at high enough concentrations can cause eye irritation; aggravate respiratory disease; suppress the body's capacity to fight infection; impair athletes' performance, and cause growth retardation in sensitive trees. Hydrocarbons in the presence of other primary pollutants (particularly oxides of nitrogen) lead to the formation of oxidants. Hydrocarbons also damage plants by inhibiting growth and causing flowers and leaves to fall . Carbon monoxide is essentially colorless, odorless, and toxic to humans. It enters the blood stream and interferes with the transfer of fresh lb oxygen. thereby depriving sensitive tissues in the heart and brain of oxygen. At high enough concentrations it can impair visual function, psychomotor performance, and time discrimination. Nitrogen dioxide at high enough exposures can cause fibrotic lung changes, bronchostriction, and acute bronchitis among infants and school children. In sensitive plants, over several months of exposure it can cause collapsed lesions near the leaf margin and moderate injury. Lead at high enough concentrations impairs hemoglobin synthesis by increasing the lead levels in the blood. Sulfur dioxide and suspended particulate exposure causes higher frequencies off acute respiratory symptoms and diminished ventilatory functions in children. 4. Sanitary Landfill Considerations Included within the study area are an existing operational sanitary landfill and a former Class II abandoned sanitary landfill . The aban- doned landfill has been covered; however, anaerobic decomposition of the organic matter present is occurring and causing settling as well as generating gaseous products which can be toxic and malodorous. The composition of gases exuded by sanitary landfills is generally 50 to 55 percent methane and 40 to 45 percent carbon dioxide with traces of other gaseous elements such as ammonia and hydrogen sulfide. The mechanism of gas production in landfills and the factors affecting it have not been well understood. Major environmental factors affecting gas production appear to be moisture content, temperature, pH, alkalin- ity, and nutrition. Generally, gas production will increase with temp- erature up to 55 degrees centigrade beyond which decomposition rates decline sharply. Additionally, less gas is produced in regions where soils exhibit lower moisture contents. Refuse placement, cover procedures, and materials can affect the move- ment of both gas and water at the surface of abandoned landfills. Land- fills covered by very tight caps which retard the release of noxious -64- gases will experience lateral migration of these gases. In this in- stance, venting systems would be needed to allow the escape of these gases, particularly because of the explosion potential and combustibil- ity of methane. For this reason, escaping gases are often "burned off" or captured with recovery wells and harnessed as a source of energy. It is important to note that non-urban air naturally contains 1.0 to 1.5 ppm methane. Methane is virtually inert (non-reactive) and therefore does not contribute to the formation of photochemical smog as other reac- tive hydrocarbons do. 5. Air Quality Management Plan (AQMP) The AQMP, adopted by the California Air Resources Board on May 10, 1979 is the air quality management plan for the South Coast Air Basin. It was designed to meet and maintain Federal and State ambient air stan- dards by 1987. Required by the Clean Air Act (Amendments of 1977), the AQMP was included in the State Implementation Plan and submitted to the Environmental Protection Agency in July 1979. The plan includes mea- sures to be implemented by the State and local agencies to achieve attainment by 1987. The plan includes 75 control measures which fall into five major categories: o Measures for cleaner industrial processes; o Measures for cleaner vehicles and fuels; o Measures to reduce congestion-related emissions; o Incentives for ridesharing; o Measures for energy conservation. 2.07.2 Environmental Impact Two types of air pollutant sources must be considered with respect to the pro- posed project: stationary sources and mobile sources. ' Stationary source con- siderations include emissions on-site from construction activities and natural gas combustion as well as emissions at the power plant associated with any electrical requirements for the project. Mobile source considerations in- clude short-term construction activities and long-term traffic generation. 1. Short-Term Impacts The primary impacts of the project are similar to those for any construc- tion activity. Grading of the site will produce two types of contamin- ants: exhaust emissions from construction equipment and fugitive dust generated by earth movement. Atmospheric dust will be generated by the mechanical disturbance of the topsoil associated with construction activities. In addition to large dust particles that settle to the earth near the construction site (often creating a localized nuisance problem) considerable amounts of fine-grained fugitive dust particles i will be emitted and dispersed over much greater distances. I -65- Dust emissions will occur during land clearing, ground excavation, cut and fill operations, and the construction of structures, roads, and parking lots on-site. These emissions will vary substantially from day to day depending on the level of activity,, the specific construction operations, and the prevailing weather. Significant amounts of fill may be necessary to develop the active recreation areas. Based upon field measurements by the Environmental Action Agency at medium activity construction sites with moderate silt content and semi-arid climates, 1.2 tons of fugitive dust per acre of construction per month of activity can be expected. The park expansion area includes 30 acres not all of which will be under constructiion at any one time. Exhaust emissions from construction activities include those associated with the transport of workers and machinery to the site as well as those produced on-site as the equipment is .used. Without a precise construc- tion plan, it is difficult to predict heavy-duty construction equipment emissions because of the day-to-day variability in construction activity levels. The temporary emissions from the predominantly diesel-powered equipment may, however, be ' significant at times although sensitive receptors are not located downwind at distances small enough to cause concern. The motor vehicle emissions from construction workers will be minor. 2. Long-Term Pollutant Emissions Long-term impacts are those associated with the permanent usage of the proposed park expansion. These include stationary and mobile source emissions. The air pollutant emissions can be projected for various years by multiplying the anticipated motor vehicle, natural gas, and electrical usage rates by appropriate emission factors. The results obtained in this manner are shown in Table H. As shown, stationary source emissions generated as a result of the pro- posed project represent approximately 14.3 percent of the total emission burden. In 1995, motor vehicle emissions will account for 85.7 percent of the project-related emissions although exhaust control technology or legislation as well as more _stringent stationary source emission control measures may alter that total . It should be noted that the bulk of the air pollutant emissions (56.9 percent or .12 ton of the .21 ton per day total ) will be carbon monoxide emitted from motor vehicles. Table I provides regional emission inventories for comparison with the project emissions. As shown, if the .project was completed immediately, the project-related emissions would represent far less than one percent (.03 percent) of the county wide emissions in 1982. Although the pro- ject is expected to be built out by 1985, the analysis addresses 1982 and 1995 for which traffic volume projections are available as well as 1982 and 1987 for which regional emission inventories are available for comparison. -66- Table H CENTRAL PARK EXPANSION AREA 1995 PROJECTED MOBILE AND STATIONARY SOURCE EMISSIONS Primary Natural Gas Electricity Vehicular Total Pollutant (Tons/Day) (Tons/Day) Tons/Day Tons/Day CO .0004 .0009 .1166 .1179 THC .0002 .0008 .0175 .0185 NOx .0026 .0104 .0307 .0437 Sox .0000 .0122 .0044 .0166 Particulates .0000 .0018 .0066 .0084 Note: Based upon a natural gas consumption rate of 44,000 cubic feet per day, an electrical usage rate of 9,000 kWh per day, a daily VMT of 19,900 miles, and motor vehicle emission factors from EMFAC 6C.

I 3. Long-Term Air Quality Projections The assessment of the project impact on localized ambient air quality requires that future ambient air quality levels be projected. Carbon monoxide concentrations can be estimated adjacent to Golden West, Slater, and Talbert using the California Department of Transportation line source dispersion model Caline 3. Because of the relative inertness of carbon monoxide in the photochemical smog formation process, and limitations of knowledge on dispersion characteristics of other air pollutant species, carbon monoxide is the most suitable tracer pollutant for microscale modeling. Secondary pollutants are a large-scale phenomenon and should be analyzed on a regional basis rather than a local one. The assumptions made in the Caline 3 modeling process are given in Appendix D. The results of the calculations appear in Table J. As shown therein, the carbon monoxide concentrations adjacent to the road- ways most heavily used by project traffic will be less than 14 ppm and well below the 40 ppm State standard and the 35 ppm Federal standard for one hour. Over an 8-hour or 12-hour period, project-related traffic along these roadways will contribute approximately 0.05 ppm to the carbon monoxide concentration at 150 feet from the road. Consequently, if the Federal 8-hour carbon monoxide standard of 9 ppm or the State 12-hour standard of 10 ppm is equalled or exceeded as a result of regional vehicular emissions, it will also be exceeded adjacent to the project site. However, project-related traffic alone will not cause the 8- or 12-hour standards for carbon monoxide to be exceeded locally. Receptors located closer than 150 feet will experience identical carbon monoxide exposures with or without the proposed park expansion.

Sanitary Landfill Considerations As mentioned earlier, the primary concerns related to the abandoned landfill on-site focus on the combustibility of the methane gas produced by the decomposition occurring and the potential for impact related to odors. The proposed expansion project includes a 2,200 space vehicle parking facility with a turf or gravel surface to cover the abandoned landfill . The escaping methane gas will be studied in detail prior to a decision on whether to vent and burn off the methane or attempt its recovery and use. In order to reclaim as much methane as possible, it will be necessary to cap the abandoned landfill with an impermeable material which will prohibit lateral or vertical migration of decomposition gases and limit the amount of oxygen entering the landfill . An uncapped or improperly capped landfill may experience reduced or suspended anerobic decomposi- tion. Further, the intrusion of oxygen could create potentially ex- plosive conditions if concentrations of 5 to 15 percent methane are permitted to develop ("Control of Gas Flow From Sanitary Landfills," Houshang Esmaili , 1975). Generally, gases are not vented from landfills by any means other than natural venting through the soil cover. Structures built on or near a landfill may therefore require protection by a forced air withdrawal or other system. The best control of odors is achieved through the rapid and continuous coverage of solid wastes and the sealing of sur- face cracks in completed landfill areas to prevent emissions of large concentrations of odorous gases. Despite these precautions, the aban- doned landfill could produce objectionable odors if disturbed during the construction process. 5. Planning Mode Alternatives Four land use alternatives have been studied by Huntington Beach City Staff for a 25-acre Planning Mode or Study Area adjacent to the Huntington Beach Central Park. The development alternatives included: a. Garden offices with an adjoining restaurant. b. Residential development at various densities. C. Recreational vehicle park. d. Commercial nursery/tree farm. The "Planning Mode Study Area Special Report" recently prepared by City staff analyzed each land use alternative and concluded that each alterna- tive would impact air quality within the South Coast Air Basin to vary- ing degrees. However, the Garden office/restaurant use alternative which has the highest impact rating of the uses considered would still represent an insignificant incremental decrease in air quality. An air pollutant emission inventory was included for each alternative and has been reproduced in Table K. i -69- • As shown in Table K, the more intense land use alternatives such as the garden offices or medium density residential development generate larger quantities of air pollutants. The recreational vehicle park or nursery alternatives generate less than 150 pounds of air pollutants daily, most of which will be dispersed over a large area by vehicles approaching or leaving the site. • Table K PLANNING MODE AIR POLLUTANT EMISSION INVENTORY Land Use Alternative Air Pollutant Emissions (Tons/Day) Garden Offices/Restaurant 0.67 Estate Residential 0.16 Low Density Residential 0.24 Medium Density Residential 0.40 Recreational Vehicle Park 0.06 • Nursery/Tree Farm 0.07 Source: Huntington Beach Planning Division, 1982. • 6. Cumulative and Growth-Inducing Impacts Cumulative impacts of growth proposed for the surrounding area have been taken into account in the ultimate 1995 analysis and the ultimate 1995 plus project analysis under "Long-Term Air Quality Projections." The proposed project is the result of previous growth inducements in the area. The project is not being proposed in a totally unurbanized area where infrastructure is absent or arterial highways do not exist. Conversely, the site is served by arterial highways and bounded by residential and other developments. The AQMP assumes a level of growth consistent with SCAG 78. The imple- mentation of the AQMP may require that some of the growth provided for in County and City General Plans be modified, eliminated, or delayed if that growth will prevent or interfere with the attainment and mainten- ance of ambient air quality goals. Since the growth accommodated by the proposed project will cumulatively impact the ambient air quality of the region, but will most likely not exceed SCAG 78 forecasts or • cause local air pollutant concentrations to exceed the relevant stan- dards, its consistency with the intent of the provisions of the AQMP is clear. • • -70- 2.07.3 Mitigation Measures The most effective air pollution mitigation measure for consideration during project design is a substantial reduction in vehicle miles traveled (VMT). This can be achieved by providing recreational opportunities near the resi- dents they are designed to serve. The project accomplishes this goal through its design and location. Measures selected for incorporation in the project include: o Adequate watering techniques will be employed to partially mitigate the impact of construction-generated dust particulates. o SCAQMD Rule 403 relative to cleanup operations during and after construc- tion will be adhered to. o The installation of thermal insulation in walls and ceilings which meets or exceeds standards established by the State of California or the Department of Building and Safety. The following mitigations are offered as suggested measures which can be incorporated as conditions of approval , should the City of Huntington Beach so determine, to further reduce the air quality impacts associated with the project. o The preferential use of diesel-powered construction equipment rather than gasoline-powered equipment, to affect exhaust emission reductions and evaporative and crankcase HC emission reductions. o The covering of all trucks filled with soil that exceed 20 mph or venture off-site. o Speed control of 20 mph on unpaved surfaces. o The balance of cut and fill quantities on-site to eliminate the need for imported or exported soil . 2.08 NOISE 2.08.1 Environmental Setting A noise assessment was conducted for Huntington Central Park in March, 1982 by J.J. Van Houten and Associates, Inc. This study (reproduced in Appendix F) evaluated existing and projected noise levels for traffic on adjoining arterials, potential activity at the ball field complex, and the existing shooting range. -71- • The analysis in regards to arterial traffic concludes that residences adja- cent to Warner Avenue, Slater Avenue, Golden West Street, Beach Boulevard, and Edwards Street are currently significantly impacted. Table L summarizes the noise measurements obtained at five locations in the general vicinity of Central Park. The area designated for the ball field activity currently does not contribute • to ambient noise levels as it has remained an undeveloped open meadow to date. Measurements of activity at the existing shooting range were obtained at a location in the southerly library parking lot approximately 600 feet north of the range. At this distance, individual weapon firing generates a peak noise level of 54 to 58 dB(A). • Using this data, the peak noise level generated at the nearby noise sensitive areas by activity at the gun range can be calculated. Thus, it is determined that the peak noise level at the library will be about 49 to 53 dB(A) and about 62 to 66 dB(A) at the nearest position on the planning mode alternative site to the gun range. It is also pointed out that under ideal climatic conditions noise generated from occasional use of the shooting range during the evening hours has been reported by residents in the downtown area.

Following is a summary of the City's noise impact assessment criteria: Table M NOISE IMPACT ASSESSMENT CRITERIA Location CNEL Range Peak Level Range Impact Residential Less than 60 dB Less than 70 dB(A) (nighttime) Insignificant 60 and over 70 and over (nighttime) Significant Public Less than 60 dB Less than 75 dB(A) Insignificant Institution. 60 and over 75 and over Significant Park Less than 70 dB ----- Insignificant 70 and over ----- Signficant Commercial Less than 80 dB Less than 80 dB(A) Insignificant 80 and over 80 and over Significant 1. Arterial Highways Figure 14 portrays the community noise equivalent level (CNEL) contours for the future (1995) traffic volumes on the major arterials within the study area for the "with project" case. These traffic volumes were obtained from the traffic study prepared and discussed in Section 2.06 of this Report. The following is noted from the noise measurements and an analysis of the traffic data developed by Kunzman Associates (Appendix B) : o A significant impact currently exists at residential locations directly adjacent to Warner, Slater, Golden West, Beach, and a por- tion of Edwards. o A significant impact is projected for residential locations directly adjacent to all arterials within the study area except for some reaches of Talbert, Ellis, and Edwards. This will occur with or without the project. In addition, a significant impact is projected for the portions of the park that are adjacent to Golden West. Again, this will occur with or without the project. I i -73- i ......._ _ , I . ....... 60� r QI „....... 1 ....�.: ..._._ 1 .T..

It is expected to be greater than 70 dB by 1995, with or without the project. Therefore, a significant impact exists and will need to be mitigated if residential construc- tion is planned for this area. • 2. Ball Park Activity. Figure 14A depicts the noise contours for the peak A-weighted sound levels that are expected to be generated by activity at the proposed recreational activities. These contours reflect the peak sound levels that will be experienced at nearby noise sensitive areas after. the • recommended noise mitigation measures have been implemented. Noise generated from the proposed ball park complex will consist of spectator and loudspeaker noise. Based on the analysis conducted by Van Houten and Associates, the maximum noise level generated by ball park activity when measured at the library and an adjacent residence is 74 to 75 dB(A) which exceeds the City' s 70 dB(A) maximum standard for nighttime noise levels for residential development, but not for public institutions (75 dB(A)). Ball park activities are expected to generate 77 to 80 dB(A) levels at the proposed YMCA, thus also exceeding the maximum standard of 75 dB(A) *for public institutions during nighttime - hours. Noise levels when measured at the northern periphery of the ` Planning Mode property are expected to be less than 65 dB(A) which is less than the maximum standard for residential development. Thus, a significant impact will exist in regards to all sensitive noise recep- tors in the area with the exception of the Planning Mode property. The peak noise level generated by the loudspeaker systems at the pro- posed ball park facilities is not expected to create a significant impact at any of the noise sensitive locations near the ball park. However, the loudspeaker systems will be clearly discernible above the ambient noise level and, therefore, represent a potential source of annoyance. 3. Shooting Range Based upon the Huntington Beach noise ordinance standards and the estimated peak noise levels generated by activity at the gun range, it is determined that an insignificant impact will exist at noise sensitive locations in proximity to the gun range. However, a significant impact may exist at some residential locations in the northern portion of the planning mode alternative site if activity at the gun range occurs during the nighttime and early morning hours (10:00 p.m. to 7:00 a.m.). In any event, the weapon firing may be annoying to residents living in proximity to the gun range since the sound will be discernible above the ambient • noise level . -75- � 1 . - tom'�:._i - _ _... _ ._ �J - -t { — i - - ' .--_..5.._ - ......._ ...-- ---- - - - - - - 1 ram; - � � - - t _ t 11 _i LIBRARY LS t S < i I Ft! � ci " - ... - - Y - - ..x- I L .: __.J _ -._ ....� - - - _ -�` a ' I. 1jj GUN N _ - - i - - •_- - _ -------_-------------------- min t , I _ 1 i _. ffs r_:_; -- :- 111111 M - J. `I e --...---.............

Construction Noise Annoyance due to construction noise during the development of the park will be minimal . Equipment associated with grading and excavation produces potential annoyance. However, the duration of this activity is only for a few weeks. Construction noise may cause considerable annoyance if it occurs after 7:00 p.m. on weekdays and during the day on • Sundays. Figure 3 identifies the level of construction activity noise, some of which will be generated by truck movements to and from the site and within the park itself. 2.08.3 Mitigation Measures • In order to provide a project which complies with the City of Huntington Beach Noise Ordinance and Noise Element, the following mitigation measures are recommended: o Activity at the ball. park facilities should be limited to the hours of 7:00 a.m. to 10:00 p.m. , pursuant to the City of Huntington Beach Noise Ordinance. o Crowd sizes at the two ball park facilities nearest to the proposed YMCA should be limited to no more than 25 to 40 people. o Bleachers and loudspeakers at the ball park facilities should be ori- ented away from nearby noise-sensitive areas whenever possible (refer to Figure 2) . o Loudspeakers should be placed at the center of a large baffle (about 4' X 4' ). o The loudspeakers should be placed near the bleachers and should be controlled so that the peak sound level (when measured at the spec- tator locations) is no greater than 75 dB(A). o An alternative to items 1 through 5, above, would be the construction of a continuous berm/wall combination around the ball park area. A combined height of about 7 feet would be needed on the north, west, and east sides and a height of about 11 feet would be needed on the south side. The barriers could be constructed entirely by use of an earth fill , or any combination of earth fill and block wall , as needed_ to achieve the heights of 7 or 11 feet. o Activity at the gun range should be limited to the hours of 7:00 a.m. to 10:00 P.M. o The type of weapons that will be used at the expanded gun range should be limited to the largest caliber currently being fired. • -77- o If a residential community is developed at the Planning Mode alterna- tive site, a noise barrier with a minimum height of 6 to 7 feet will be needed adjacent to Golden West and Ellis in order to reduce -traffic noise to acceptable levels. 2.09 VISUAL AND AESTHETICS 2.09.1 Environmental Setting Huntington Central Park, in its existing state, provides much-needed visual relief from the highly urbanized character of the region through its rural and passive nature. Walks and paths wind through open spaces which contain large groves of trees, lush vegetation, wildlife, and lakes. Observation shelters, restrooms, and two concessions are interspersed throughout the park to cater to picnicking and nature observation by park users. Figures 15, 16, and 17 provide a pictoral description of Central Park in its present state and proposed expansion areas. Figure 18 provides a locational index for these illustrations. 2.09.2 Environmental Impact Implementation of the proposed Central Park Master Plan will have the effect of modifying the present passive nature .of the park area by incorporating a variety of active recreational uses. A restaurant, a 2,200-car parking lot, expansion of the existing shooting range, a fishing lake, and various development alternatives for the Planning Mode area are proposed in the southeasterly portion of the park (southeast of the intersection of Golden West Street and Talbert Avenue) . Development of these activities at the proposed locations will not significantly affect existing segments of the park from a visual standpoint. It is believed that the development of these facilities will improve the visual quality of this area which is currently occupied by the landfill , the mushroom farm, and other scattered development. No additional park development is proposed for the northeasterly portion of Central Park (northeast of the intersection of Golden West Street and Talbert Avenue) which contains Talbert Lake and the City Library. This visually appealing segment of the park is currently devoted to passive activities which are proposed for retention. Major alterations are proposed in park areas to the west of Golden West Street which contain Huntington Lake, the equestrian area, the frisbee golf course, the midden area, and the nature observation area. Proposed modifications include expansion of the park southerly to Ellis Avenue to facilitate an area for a relocated frisbee golf course and recreational trails; relocation of i -78- • the equestrian center to the southeast corner of Huntington Lake; the develop- ment of a Y.M.C.A. building along Golden West Street; and a lighted ballfield complex along Golden West Street to the southeast of the existing nature area. A park-oriented commercial area outside of the park boundaries is planned at the northwest corner of Ellis Avenue and Golden West Street. Huntington Lake, the midden area, and the nature observation area are to be retained. Of special concern is the relationship of the ballfield complex to the exist- ing residences located approximately 500 feet to the west and the existing nature area adjacent to the north. Noise and glare impacts upon the resi- dential area are minimum primarily due to the 550-foot distance separating these uses. Within this 600-foot buffer area is a series of dense tree • stands which significantly reduce the potential visual impact upon the resi- dences. Additionally, landscaping and mounding are proposed near the peri- meter of the playfields which will further ensure that the viewshed from the adjacent residences is not adversely affected. (This topic is discussed further under Section 2.08.) • Impacts upon the nature area are more apparent because of the close proximity of the two activities. A dense buffer has been proposed between the two areas, but special attention will be necessary to alleviate potential impacts resulting from more intense public use, glare from lighting, and noise which will unavoidably disturb the serenity of the nature area. From an overall standpoint, implementation of the Central Park Master Plan will alter the general aesthetic character from an open space, rural atmosphere to one oriented more towards active recreational use. 2.09.3 Mitigation Measures • In implementing proposed plans, special care should be devoted to providing buffer areas which provide gentle transitions from incompatible uses such as the residential and nature area affected by the ballfield complex. Parking areas and all active recreational facilities should be landscaped with plant materials that are currently found in the park to minimize significant visual differences throughout the park. All lighting fixtures should be directed inward to confine light and glare to the area intended for illumination, particularly in relation to the ballfield complex where light standards may be up to 80 feet in height. • • • -79- ?k . g • ,� :.__ ,. _� .� �•�� •"`_;"� ,, � ,a.r ;} ` �.+t`�� t^ � r- '„ ;� Ra -. .v aF ,. s �+��* �� ;_•��'t t }byµ � s -.."...«;."';'_�' .- *-. � -.�.�*a.. _ .rt>.°. e: �F�7�� yl t..t � ''F} S�'^�:�e'�'t����„k,.� ��� '"`:ri r...�c�.��e=+br �P, .i.`-""".•.r,Kr r-ac{ ivP- - o- tax,: 5 }'?-'t� _ a 'ASOf l* y c ,t t #x_:C - ;s t Srt - -,,� t a` � -- -a�-,+ - �-� d '9•�' " �4 {:� i�rtC }i �4Far� dS b. p It' "nM.�'(I f'_•f Y.

Environmental Setting The Huntington Beach Police Department Headquarters are located in the Civic Center at the southeast corner of Main Street and Yorktown Avenue. The station is located approximately two miles south of the center of Huntington Central Park. Response time to the park facilities would likely be within five minutes. The Department currently maintains regular patrols throughout the area. A fire station exists within one-half mile of Central Park southeast of the intersection of Talbert Avenue and Golden West Street. Due to the proximity of the fire station, response times would generally be within five minutes. • 2. Environmental Impact Increases in active recreational activity in Central Park will likely increase demand for police responses. In a previous study conducted by the City' s Planning Department, it was determined that up to two addi- tional officers would be necessary to accommodate development of the Planning Mode Area. Although it has not be specifically determined, it is likely that addi- tional patrols will be required upon implementation of the Central Park Master Plan. None of the facilities contained within, or proposed for, Central Park represent a significant hazard in respect to fire potential . Responses required from Fire Department personnel would likely be limited primar- ily to Paramedic squad responses to injuries incurred by park users. • The proposed project is not believed to generate any major impacts to the Huntington Beach Fire Department. 3. Mitigation Measures • Prior to approval of any specific site plans for proposed park activities, these plans should be submitted. to the Police Department for review and recommendation. Through the development and expansion of the park and associated facili- ties, adequate access should be provided for on-site circulation for Fire Department equipment and operations. • -84- 2.10.2 Electricity, Telephone, and Gas 1. Environmental Setting Electrical service has been extended to various portions of the park to support existing activities by the Southern California Edison Company. The proposed project is located within the jurisdictional boundaries of the General Telephone Company. Telephone service already exists to various facilities within Central Park and existing lines are adequate to serve the currently proposed and future expansion. Gas service is provided to the City of Huntington Beach by the South- ern California Gas Company. Gas lines exist in sufficient locations and sizes to serve the ultimate needs of Huntington Central Park's facilities. According to the Gas Company, the continued long-term supply of natural gas is subject to gas availability and State and Federal regulatory policies. 2. Environmental Impact Upon construction of the proposed park land uses substantial quantities of electricity will be required. The proposed ball field complex will utilize 46 poles, each of which contain 8 fixtures with 368 lights each of 1000-1,500 watts. The proposed equestrian center, expanded shooting range, restaurant, Y.M.C.A. , Planning Mode, lake aeration systems, and parking lot lighting will also be major electrical consumers. Due to the conceptual nature of the Central Park Master Plan, it is presently impossible to deter- mine the quantities of electricity to be consumed. The proposed project will not significantly affect telephone or natural gas service delivery in the area. 3. Mitigation Measures Metal halide or other energy-efficient lighting such as high-pressure sodium should be utilized for outdoor lighting for parking areas and the ball field complex to produce the maximum amount of light while minimizing electrical consumption. No mitigation measures are proposed for telephone or gas utilities. • -85- • 2.10.3 Water, Sewers, and Storm Drains • 2.10.3.1 Environmental Setting 1. Water • The master planned water delivery system for the Central Park area proposes loop water systems with 12-inch to 14-inch mains in each street suurrounding or traversing the site. In-place facilities which are up to master planned standards exist in Golden West Street, Gothard Street, Talbert Avenue, Slater Avenue, and Lakeview • Drive. 2. Sewers Sewer service along the perimeters of Central Park exist in sizes • and quantities which meet Master Plan specifications. Sewer ser- vice within Central Park, however, has not been fully developed and is inadequate to meet the demands created as a result of the proposed project. • 3. Storm Drains Drainage in Central Park is largely a function of the three existing lakes. This has created numerous problems which are discussed in the hydrology section of this report. The park' s storm drain system is currently largely unimproved and will require drainage measures • to support the proposed project. 2.10.3.2 Environmental Impact • 1. Water Construction of proposed facilities in Central Park and the Plan- ning Mode area will require completion of the loop water system in accordance with the City' s Master Plan. Twelve-inch water mains will be required in Edwards Avenue between Ellis Avenue and Inlet • Drive (to be located parallel to the 42-inch water main which al- ready exists in Edwards) and in Ellis Avenue between Edwards and Gothard Street (a short segment already exists to serve the exist- ing stables west of Golden West Street). • • -86- The proposed Restaurant and YMCA may necessitate water facilities improvement beyond the facilities master planned. However, the Park Master Plan does not provide specific information relative to size and anticipated consumption. 2. Sewers Development of the proposed project will necessitate upgrading of the sewage collection systems to master planned specifications. Specifically, a 12-inch sewer main will be necessary between Ellis Avenue (from approximately 1,300 feet east of Edwards Street) and Golden West Street (to approximatley 700 feet north of Talbert Avenue). Special attention must be addressed to the sewerage requirements of the equestrian facility, the restaurant and the YMCA. Equestrian facilities and wash racks should be designed such that horses and horse areas can be washed down in designated wash areas. Wash areas should be covered by a roof and graded such that rainwater drains around the wash area. Furthermore, the drain should be covered with a metal grate (with 1" to 1 1/2" opening) and kept free of hay and other debris which may otherwise clog its opening. This sewer line would connect with a 12-inch sewer main. Horse droppings should also be placed into sealed containers and periodi- cally removed from the site for proper disposal in accordance with County Health and Sanitation Codes. The YMCA and Restaurant facilities will connect to the existing 8- inch sewer main in Goldenwest Street. Depending upon the sewage outflow of these two facilities an additional sewer line parallel to the existing line may be needed. 3. Storm Drains Implementation of the proposed project will require the construction and extension of several storm drains. A 60-inch storm drain is required between Ellis Avenue and Hunting- ton Lake. A bypass storm drain should connect this storm drain to the existing bypass along the westerly shore of Huntington Lake. Remedial action is also necessary near Sully-Miller Lake. A 102- inch storm drain should be constructed under Ellis Avenue to connect to a proposed bypass along the easterly shore of Sully-Miller Lake, which in turn should connect to the existing 36-inch storm drain which connects Sully-Miller and Talbert Lakes. In addition, the operability of this 36-inch drain will need to be investigated as blockages may exist. i i -87- r 2.10.3.3 Mitigation Measures All water, sewer, and storm drain facilities should be upgraded con- sistent with the City's Master Plan to adequately service proposed park activities. Additionally, bypass storm drains should be constructed along Huntington and Sully-Miller Lakes to prevent excessive runoff from causing large water level fluctuations. The equestrian facility should be properly designed to a sewer facility to collect residue from the site. Horse wash areas should be covered by a roof and graded such that rainwater runoff bypasses the wash area. A metal grate shall be placed over the drain and shall be kept free of debris. 2.10.4 Fiscal Impact Analysis 1. Park Uses The following analysis provides an estimate of the anticipated annual costs in the provision of specific public services relative to uses proposed in Huntington Central Park. This analysis was performed utiliz- ing the City's Land Use Fiscal Impact Model (Ultrasystems) and revenue/ cost data provided in the "Final Report on An Economic Feasiblity Analysis. ..Within Huntington Central Park" (Ultrasystems). While these reports provide the basis for the following analysis, several assumptions had to be made due to the conceptual and recreational nature of the project. The summary analysis which follows is supplemented by the analysis worksheets located in Appendix G. FISCAL IMPACT ANALYSIS SUMMARY a. Estimated Annual Services Costs o Ball field Complex $147,321.60 ' o Equestrian Center $104,176.65 o Restaurant $ 10,228.19 o YMCA $228,432.42 -- o Fishing Lake $ 22,800.00 o General Park Use $185,458.20 Total $698,417.00 b.

Planning Mode (Planning Mode Study Area Special Report) The City fiscal impact model projects that over a ten year period, 1982- 1992, a garden office complex (with an adjoining restaurant) located on the planning mode site would create a negative cash flow for the City of $378,574. High administrative, fire, police, and street maintenance costs are assumed to far outweigh any return revenue to the City generated by the development. The alternative would generate little in the area of sales tax revenue. All of the residential alternatives considered for the planning mode property are projected to generate a revenue surplus. Primarily through property taxes, estate residential development of 71 units would produce $106,421 in City revenue over ten years. A low density development of 148 units is projected to generate $49,495 and a medium density develop- ment of 285 units is expected to create a positive cash flow of $126,251. Of all the land use alternatives considered, the R.V. camping facility is projected to generate the highest amount of revenue for the City. With a 40-percent annual occupancy rate and a $10 nightly fee, a 580- space facility located on the planning mode site is projected to create a positive cash flow of $5,753,620 over a ten-year period. Although a 40-percent annual occupancy rate is projected by staff, the R.V. development would break even if only a 15-percent annual occupancy rate were maintained. It must be noted, however, that the above revenue projections do not include the initial land acquisition, facility development, or infra- structure costs for a City operated R.V. campsite. Taking into account these factors, a 580-space facility would not begin to pay for itself until after ten years. The nursery/tree farm alternative is projected to have a highly negative cash revenue ratio. The principal revenue sources, property and sales tax, are low due to the few structures required and the largely wholesale nature of this use. Total costs are projected to outrun total revenue by a margin of 7 to 1, or a $1,529,088 negative cash flow. • 2.11 ENERGY CONSIDERATIONS 2.11.1 Environmental Setting Urban areas consume nonrenewable energy sources for transportation, residen- tial heating and cooling, etc. The most commonly used energy sources are gasoline for motor vehicles and natural gas and electricity for residential and other land uses. In their present use (vacant), no energy is expended within the areas proposed for expansion and modification. Several factors related to the site present potential measures in efforts of conserving energy. They are: 1) use of trails; 2) solar access; and 3) recovery of methane gas from the landfill site. -89- 2.11.2 Environmental Impact • The construction of facilities and improvements on the project site will consume quantities of nonrenewable energy resources. During grading and construction activities the equipment will require petroleum products. Upon completion, the proposed facilities will require electricity, natural gas, and petroleum products. The amounts to be consumed represent irretrievable quantities of energy and therefore will contribute to a diminished supply. • In addition to the gasoline consumed by citizens traveling to and from the park, natural gas and electricity will be consumed on the site by the YMCA structure, the Equestrian Center, parking lot and ball field lighting, lake aeration systems, shooting range, restaurant, and Planning Mode development. • Specific quantities of resources consumed are difficult to determine at this time due to the conceptual nature of the Master Plan. Several energy-conserving measures can, and should be, incorporated into the project where feasible. Both the Southern California Gas Company and the Southern California Edison Company have a program to help consumers in plan- ning to conserve energy. Measures designed to reduce the vehicle miles • traveled by future users of the park area would probably have the greatest single effect on the total energy consumption. The land use plans of the overall master plan incorporate a network of bikeways and equestrian trails. The bikeways could be used in lieu of auto use, but it is doubtful that the equestrian trails will be used for anything other than recreation given the • recreational nature of the project. Considerable research has recently been conducted in the solar energy field. Within the next few years new methods of utilizing energy from the sun could be available for incorporation into development. Even today there are certain methods which can be employed to take advantage of the sun for heating and • cooling buildings. West-facing walls will be the greatest source of direct solar heat gain during the summer, and south-facing walls the greatest source of direct solar heat gain during the winter. It is possible that the use of solar panels will not only become practical , but commonplace, within the next decade. • Finally, the City is investigating the use of methane gas which may possibly be tapped from the inactive landfill site and used as an energy source to produce heat and electricity. However, this opportunity has not been fully explored by the City to determine its actual feasibility. • 2.11.3 Mitigation Measures The following mitigation measures are recommended to lessen the project's consumption of nonrenewable energy resources. 1. Implementation of energy conservation measures outlined in "Energy Con- servation Standards for New Residential Buildings" of the California Ad- ministrative Code, Title 24, Part 6, Article 1, as amended July 26, 1978. • -90- 2. Appropriate use of shade trees to minimize direct solar irradiation on west and southwest building surfaces. 3. Use of energy-efficient exterior lighting fixtures such as metal-halide or high-pressure sodium. 4. Use of active solar water heating in commercial uses on-site. 5. Use of other active or passive solar measures where practical . 2.12 SAFETY CONSIDERATIONS 2.12.1 Environmental Setting The orientation and close proximity of the shooting range (as existing and as proposed for enlargement) relative to the public landfill raises the potential and, in fact, past occurrence of stray bullets landing in the immediate work • area. 2.12.2 Environmental Impact Enlargement of the shooting range facility will increase its use by private citizens and by public agencies which would practice with automatic weapons. Increased usage would result in a greater number of stray bullets landing in the landfill area thereby increasing the chances of injuring or fatally wound- ing a worker or other persons on the landfill site. 2.12.3 Mitigation Measures The expanded shooting range facility should be developed with overhead baffles or range limiters along the entire length of the shooting range. Such devices would reduce or eliminate stray bullets from the immediate site. • i -91- CHAPTER 3.0 TOPICAL ISSUES • • • • 3.0 • TOPICAL ISSUES 3.01 CUMULATIVE IMPACTS • Cumulative impacts occurring as a result of the implementation of the Hunting- ton Central Park Master Plan are largely limited to traffic and air quality considerations. As discussed in Section 2.06 (Traffic and Circulation) , traffic generated by the project will increase volumes on nearby arterials of which several are • expected to be near or beyond capacity by the year 1995. It should be noted, however, that the arterials which are expected to exceed capacities will do so with or without the implementation of the proposed park development. In regards to air quality, the Air Quality Management Plan (AQMP) assumes a level of growth consistent with SCAG 78. The implementation of the AQMP may • require that some of the growth provided for in County and City General Plans be modified, eliminated or delayed if that growth will prevent or interfere with the attainment and maintenance of ambient air quality qoals. Since the growth accommodated by the proposed project will cumulatively impact the ambient air quality of the region, but will most likely not exceed SCAG 78 forecasts or cause local air pollutant concentrations to exceed the relevant • standards, its consistency with the intent of the provisions of the AQMP is clear. 3.02 SHORT-TERM EFFECTS VERSUS LONG-TERM PRODUCTIVITY • The proposed Central Park Master Plan will have a long-term effect of preclud- ing typical urban development patterns such as residential , commercial , and industrial land uses. The proposed project will commit certain areas within the park such as the YMCA, the Equestrian Center, the ball field complex, and the Planning Mode property for these specific uses for extended periods due • to the construction of permanent structures. Other areas in the park will be conserved largely in open space presumably for an extended period as well , but will not be subject to permanent improvements. In preserving the Central Park area for open space and recreation, long-term productivity will be enhanced by properly maintaining the park's facilities • for the enjoyment and benefit of the community. • • -92- i 3.03 UNAVOIDABLE ADVERSE IMPACTS Although mitigation measures are recommended for some of the anticipated impacts resulting from the project, some of the impacts addressed in this environmental impact report are seen as being partially, if not totally, unavoidable. Such adverse impacts are seen as a direct or indirect result of the proposed project. Implementation of the proposed project will thus result in the following: I o Loss of developable, vacant space. o Incremental increase in air pollution from motor vehicles. o A slight increase in demand for energy and nonrenewable resource. o Increased traffic on surrounding streets within the study areas. o Minor increase in demand for public services and utilities. o Incremental increase in noise levels within the study area. o Increase in population within the study area, depending on which Planning Mode alternative is selected. o Partial loss of the open space-oriented, passive nature of Central Park. o Land use contrast between the proposed ball field complex and exist- • ing residential uses and the nature observation area due to noise and lighting. 3.04 GROWTH INDUCEMENT The Central Park Master Plan is not seen as a growth-inducing measure but, rather, as being growth-accommodating. Implementation of the project will not extend public services to areas which could subsequently be developed. Public facilities which will be extended to the site are basically in-filling measures which are in full conformance with the City's Public Works Master Plans. The project may accommodate more intensified urban growth in the vicinity by providing substantial visual relief from urban development pat- terns and by providing ample passive and active recreational opportunities to the community. • -93- • 3.05 PROJECT ALTERNATIVES • 3.05.1 "No Project" Alternative The "no project" alternative would amount to a freeze of park boundaries in their present location; terminating any future consideration of purchasing property for park purposes in the area designated for park expansion; and terminating ,any consideration of purchasing property in the "Planning Mode" area for park use. Moreover, undeveloped portions of the park would remain undeveloped for an undeterminable period of time. Given the "no project" alternative several environmental and land use issues • would remain present posing concerns the City may be obligated to study and resolve. They are: 1. . Water Quality Associated With Talbert and Sully-Miller Lakes - Current drainage conditions and the lack of adequate water quality improvement efforts will result in the current and potentially worsening water qual- ity conditions evident in Talbert and Sully-Miller Lakes. Moreover, Sully-Miller Lake, being a former quarry pit, is visually unattractive in its present state. 2. Private Equestrian Area Use - A privately operated equestrian use is presently situated on portions of property located north of Ellis Avenue • and west of Golden West Street. In addition to this use operating with minimal health, safety, and aesthetic standards, water drainage from the site picks up and carries relatively high concentrations of equine urine and feces into Talbert Lake. The proposed project would result in the development of a new equestrian area with supplemental landscaping and more adequate facilities to allow for healthier methods of equine • management. Moreover, importantly, the City would be the leasor and may exercise greater authority in controlling negative aspects of the use. 3. City Owned Property - Several acres of land within the present park oundaries and immediately adjacent to the park (encyclopedia properties) have been acquired by the City for ultimate park use. Such properties • would become surplus and may be subject to sale for development. Finally, the no project alternative would result in the elimination of "nega- tive impacts" which have been identified and associated with the project. • 3.05.2 Open Space - Private Development The proposed expansion area is presently designated as open space in the Land Use Element. This area could be rezoned to Recreational Open Space (ROS) in order to restrict residential use and provide for compatible activities and uses. Rezoning properties to ROS without amending the Open Space/Conservation • Element would not, however, allow the City to take advantage of State and Federal sources for additional acquisitions. • -94- Use of the property, under this alternative, may revert to private develop- ment and operation of an open space/recreational activity by lease or sale of property by the City. A prime example of use that may be considered could be a golf course. However, as discussed in a following alternative, the Ultrasystems.' Economic Feasibility Study it is questionable whether a golf course coulc operate profitable without complimintary uses including the need for a hotel . Such a use was found to be inconsistant with the primary intent of the City to establish a community oriented facility, not to mention the greater impacts on traffic, noise, visual , and other factors of the local environment. 3.05.3 Scaling-Down Proposed Recreational Uses This alternative consists of reducing the intensity of proposed recreational uses to improve their compatibility with existing uses in and around the park. As an example, the ballfield complex could be reduced from six play- ing fields to three decreasing various impacts resulting from noise, light, glare, air quality, and traffic generation upon the adjacent residences and nature observation area. This alternative would also serve to reduce the number of trees to be lost in order to accommodate the project. In addi- tion, less parking would be necessary and this area could be devoted to open space. The use of the Planning Mode property for a low-intensity use such as a nursery/tree farm would also reduce impacts on air quality, noise, and traffic patterns and would help retain an open space character. However, this alternative would not fully achieve the City's objectives as stated in Section 1.02 of this Report. 3.05.4 Previous Alternatives Considered The City retained the services of Ultrasystems Incorporated which prepared an "Economic Feasibility Analysis of Proposed Revenue-Producing Uses to be located within Huntington Central park" (May,, 1981). This study was instru- mental in the City's project investigation and alternative concept review procedure which eventually led to the present master plan concept assessed in this EIR. The study investigated numerous recreational activities and presented alternative concept plans. Reference is herein made to the de- tailed description and analysis of each alternative discussed in the Economic Feasibility Report (on file in the City of Huntington Beach, City Clerk 's Office). Following is a brief description of the alternatives studied: Alternative 1 This alternative configuration was limited to the present central park boundaries. Two land use alternatives were considered: a. The first configuration focuses on the creation of a relatively passive resort atmosphere through the development of a hotel/ conference center, a golf course, fishing lake, and the YMCA. Not enough space remains for an RV park, thus a small parking area is provided adjacent to the fishing lake. -95- • b. The second configuration is based on development of a 6-field • baseball/sports field complex in conjunction with an arcade and pizza parlor, the fishing lake, YMCA and amphitheater in the cur- rent remaining portion of the Bruce Bros. Pit. Alternative 2 The acquisition of the parcel on the northeast corner of Golden West and Ellis provides an opportunity to expant alternatives la and lb so as RV park west of the fishing lake as well as to place a baseball/sports field complex on either side of Gilden West. In addition, an equestrian facility can now be incorporated with a golf course use whereas this was • not possible within the boundaries of Alternative No. 1. Alternative 3 The acquisition of the Marion property at the northwest corner of Golden • West and Ellis provides the opportunity tto expand those golf-oriented alternatives to as large as 122 acres for golf and still include some of the key features and uses shown in the alternatives for Configuration No. 2. • Alternative 4 Alternative 4 includes the expansion of Huntington Central Park to achieve a total of 367 acres which permits the opportunity of either a golf-oriented resort theme or a non-golf-oriented resort theme, whichh would include an amphitheater. The acquisition of the 9-acre parcel on • the northwest corner of Gothard and Ellis enables the provision of an additional 250 spaces for RV use. As a matter of fact, because of its location in the Gothard industrial corridor, this is probably the best use for this parcel if it were to be included in Central Park. • • • -96- CHAPTER 4.0 REFERENCES M Q 4.0 i REFERENCES 4.01 BIBLIOGRAPHY "Geotechnical Inputs," Huntington Beach Planning Department, February, 1974.

The review and comment period extended from May 10, 1982 to June 23, 1982. S A copy of the distribution list is on public file and available for inspection at the City of Huntington Beach, Development Services Department. The following pages contain a restatement of the. comments received from various reviewing agencies commenting on the Draft EIR and a summary of the response which is contained in the text of the Final EIR. A copy of the • letters received follows in Subsection 5.02 As required by the California Environmental Quality Act, relevant comments received on the Draft EIR during the public review period shall be responded to and copies of the response provided to the commenting agency. This section contains the responses to comments made on the Draft EIR. However, to provide . decision makers with an informational document which incorporates all relevant concerns, responses to relevant comments have been embodied within the text of this Final EIR where appropriate. The responses to comments follow: 1. HILARY J. BAKER, SENIOR ENGINEERING AIDE COUNTY SANITATION DISTRICTS OF ORANGE COUNTY - MAY 14, 1982 COMMENT 1: "This office has reviewed the EIR for Huntington Central Park and takes exception to the following comment on page 87: 'Equestrian facilities and wash racks should be designed such that horses and horse areas can be washed down such that the residue• drains into an improved sewer drain. ' Please be advised that the waste from animal care areas is not an accept- able waste to the Sanitation Districts ' sewerage facilities. It will be ` necessary to make other arrangements for the disposal of this water • product." • -100- RESPONSE 1: A telephone conversation on July 2, 1982 with Mr. Tom Dawds, Deputy Engineer of the County Sanitation Districts, revealed that the Districts ' concern is the potential for clogging of drains caused by horse debris and rainwater drainage. The statement taken exception to has been corrected on Page 87 under the topic of Sewers. In addition, Section 2.10.3.3 - Mitigation Measures (P. 88) has been amended accordingly. 2. DICK HSU, ENVIRONMENTAL COORDINATOR ORANGE COUNTY TRANSIT DISTRICT - MAY 20, 1982 COMMENT 2A: . "Route 25 currently operates on Goldenwest with a 30-minute frequency. We suggest that you consider designing bus improvements into the ulti- mate width of the street (i .e. , pavement sections, turnouts, sidewalks, etc.)." RESPONSE 2A: The need for bus facilities to service Huntington Central Park is acknowledged and can be facilitated by the addition of the following mitigation measure on Page 61, Section 2.06.3: "8. Prior to the approval of detailed engineering plans for the ultimate development of Golden West Street, the City of Huntington Beach should incorporate appropriate input from O.C.T.D. as to the location and design of bus facilities." COMMENT 2B: "Additionally, service could be implemented on Edwards, Ellis, Talbert, Slater and Gothard in the future. The potential bus stops are shown on the attached map. Facilities similar to those provided for on Goldenwest should be designed into these streets." RESPONSE 2B: In developing and approving detailed engineering plans for these streets, consideration should be given to the fact that bus services may be initiated. The design of these streets should be such as not to exclude the development of bus stop facilities. i i -101- • 3. VINCENT G. MOOREHOUSE, DIRECTOR OF COMMUNITY SERVICES CITY OF HUNTINGTON BEACH - JUNE 1, 1982 COMMENT 3A: "Concerning subject EIR, this department feels that the issue of possible expansion of the Police Firing Range should be addressed. At present, staff is negotiating a new lease for the range which includes reconstruc- tion of the premises to allow the public to shoot an American Standard Course for handguns, construction of a multistoried structure to include additional shooting stations, classrooms, public restaurant, sporting goods store and gunsmith shop." • RESPONSE 3A: The project description relative to the proposed expansion of the shooting range facility was amended to reflect current plans to include a two-story structure. The project description was amended on Page 13 (Section 1.04 II-3) and on Page 16 (Table A). COMMENT 3B: • "Additionally, provision of security should be addressed. Staff working at the public landfill adjacent to the range has reported several inci - dents of stray bullets from the range landing in their immediate work area (see Jim Way, X-5287)." RESPONSE 3B: Section 2.12 - Safety Considerations (P. 91) has been added to the Final EIR, accordingly. • COMMENT 3C: "Also, the noice factor should be studied. Residents in the downtown have reported hearing rounds from the range at night." RESPONSE 3C: A noise study was conducted the results of which were documented in the Draft EIR, Section 2.08 (P. 71). However, Section 2.08.1 - Environmental Setting has been amended to reflect the reported noise impact upon the downtown area (P. 72). • • -102- 4. JOHN A. HINTON, P.E. , ENFORCEMENT SECTION HAZARDOUS WASTE MANAGEMENT BRANCH DEPARTMENT OF HEALTH SERVICES STATE OF CALIFORNIA, HEALTH AND WELFARE AGENCY - JUNE 7, 1982 COMMENT 4: "This office's regular staff on March 10, 1980 inspected and sampled the soil in an area in which drilling muds were disposed of. The investiga- tion was at the request of the City of Huntington Beach after the area had been cleaned-up. All samples upon analysis were determined to be non-hazardous. Additionally we have reviewed the Abandoned Site Groups file and found nothing in it to indicate that the Bruce Bros. Pit is a 'potential hazardous waste disposal site. ' Therefore, based upon the information available to this office, we do not consider the Bruce Bros. Pit a 'pontential hazardous waste deposal site. '" RESPONSE 4: Discussions in the Draft EIR which indicated "potential hazardous waste" associated with the Bruce Brothers Pit have been amended accordingly. This includes amendments to the following sections of the Draft EIR: Section Title Page of DEIR Page of Final EIR N/A Summary 3 and 4 1 2.01.1 Environmental Setting 29 25, 29 2.01.2 Environmental Impact 30 29 2.01.3 Mitigation Measures 32 29,30,31 5. KENNETH E. SMITH, MANAGER ENVIRONMENTAL ANALYSIS DIVISION ENVIRONMENTAL MANAGEMENT AGENCY COUNTY OF ORANGE - JUNE 16, 1982 COMMENT 5A: "The EIR should show the derivation of usage rates for natural. gas and electricity given in the air quality appendix." i -103- RESPONSE 5A: In view of the lack of definitive site specific information on energy usage from City staff and the public utility companies, the following conservative assumptions were made to estimate the future energy usage on-site: o Equestrian Facilities: 10 percent building coverage, 52 cubic feet of natural gas per square foot of floor space annually, 32.5 kilowatt-hours per square foot annually. o Shooting Range: 15 percent building coverage, 52 cubic feet per square foot of floor space annually, 16.3 kwh per square foot annually. o Ballfield: 40,000 square feet, 52 feet of natural gas per square foot annually and 32.5 kwh per square foot annually. o Mobile Home: 9,125 cubic feet of gas per month per dwelling unit and 4.0 kwh per square foot annually (assuming 1,000 square feet of floor- space). o Restaurants: 6,000 square feet of floor space, 660 cubic feet of gas per square foot annually and 76.9 kwh per square foot annually. o YMCA: 20,000 square feet of floor space, 220 cubic feet of gas per square foot annually and 32.5 kwh per square foot annually. • o Parking Lots: Electric lighting with a required lighting level of 1 to 2 foot-candles and a uniformity ratio of 6 to 1 for average illumination/ lowest level , for a total or approximately 450 kwh per day in all parking areas combined. o Lake Aeration Systems: Compresssors and diffusers - negligible. As shown in the report Appendix, the energy consumption rates were derived from the SCAQMD Handbook and yielded a total project demand of 44,000 cubic feet of natural gas and 9,000 kilowatt hours of electricity daily. • COMMENT 5B: "The motor vehicle emissions factors for total hydrocarbons should be 1.42 gm/mi in 1982 and 0.58 gm/mi in 1995." RESPONSE 5B: Per EMA direction, crankcase blowby, diurnal emissions and hot soak emissions of hydrocarbons were added to the tabularized total hydrocarbon emission factors above as shown on the following page: • • -104- THC Emission Factors 1982 1995 Base Value 1.42 0.58 Crankcase 0.032 0.0006 Diurnal 0.196 0.044 Hot Soak 0.68 0.174 TOTAL Thus 2.33 gm/mile and 0.80 gm/mile were used in the analysis as shown in the Air Quality Report Appendix. COMMENT 5C: "Results of the CALINE3 computer runs should be reproduced in the air quality appendix." RESPONSE 5C: Refer to the air quality appendix in this Final EIR which now includes the results of the CALINE3 computer runs. COMMENT 5D: "Note for your information, that stability Class F is the worst case." RESPONSE 5D: The site is located in the coastal zone and benefits from a pronounced land/sea breeze regime. Stability Class F conditions would be highly unlikely given the project's location with respect to the ocean and surrounding topography. Additionally, telephone communications with Mr. Iry Borrow (air quality specialist at CalTrans familiar with the Caline 3 Program) led to the use of Stability Class E during the peak hour runs and Classes C, D, and E during off-peak hours. COMMENT 5E: "On page 53, last paragraph, the report states that the section of Talbert between Edwards and Golden West is not shown in the City's Circulation Plan. It should be noted that there is an inconsistency between the City and County Master Plan of Arterial Highways (MPAH) ; the County plan shows Talbert continuous between Edwards and Golden West." i i -105- • RESPONSE 5E: The last paragraph on Page 53 of the DEIR (Talbert Avenue) has been amended to reflect the MPAH. COMMENT 5F: • "On page 59, last paragraph, the report discusses the potential future realignment of Talbert to connect to Ellis. The report should also discuss the potential feasibility of connecting the discontinuous sec- tions of Talbert via an alignment south of the lake. This connection, along with the Talbert Street bridge crossing the Santa Ana River, • would provide through travel for east/west traffic. It should be noted that one reason for the projected heavy volumes and associated capacity problems on Warner, is the lack of parallel facilities serving destina- tions to the east (i .e. , South Coast Plaza). The proposal to extend Talbert to Ellis will not alleviate this problem, since Ellis terminates at the river and traffic is redirected north, on to Euclid." • RESPONSE 5F: The paragraph referring to the potential future realignment of Talbert Avenue (P. 59 and 60) has been amended to reflect a second possible connection of ! the discontinuous segments of Talbert Avenue via an alignment south of the Lake. The projected heavy volumes and capacity problems on Warner Avenue are so noted. COMMENT 5G: "On page 60, Mitigation Measures section, the report should consider a southbound right turn only lane on Golden West at the park entrance. This will relieve queuing problems during peak hour and special event uses of the park." RESPONSE 5G: An additional mitigation measure has been added to Section 2.06.3 (PP. 60 and 61) which reads: 9. To relieve queuing problems during peak hours and special events at the park, the City should consider a southbound right-turn-only lane on Golden West Street at the park entrance." -106- 6. DARYL D. SMITH, SUPERINTENDENT PARK, TREE & LANDSCAPE CITY OF HUNTINGTON BEACH - JUNE 14, 1982 COMMENT 6A: "The E.I.R. , is rather deceptive regarding size, location and disruption to existing park caused by proposed ballfields." RESPONSE 6A: The Draft EIR was prepared for .a conceptual design of the Central Park Master Plan and, as a result, does not provide the detail which would otherwise be available from park improvement plans. However, even on a conceptual level the Draft and Final EIR's do identify the approximate size and location of proposed uses and facilities. Furthermore, the EIR provides an adequate level of impact assessment and mitigating measures to allow the public and decision makers to review the project and make an intelligent judgement as to the severity of impact which could likely arise from the project, if developed. COMMENT 6B: "The proposed ballfield complex is the one feature of the Huntington Central Park improvement project that creates serious impacts to the entire area in and around Huntington Central Park." RESPONSE 6B: As indicated in the EIR, the major impacts arising from the ballfield complex result from nighttime lighting (Section 2.04.2, PP. 44 and 45), noise genera- tion (Section 2.08.2, P. 75) , and the loss of numerous trees (Section 2.03.2, P.43) , among others. COMMENT 6C: "None of the mitigating measures are substantial enough to satisfac- torily solve the problems created by the size and anticipated use of the ballfields." RESPONSE 6C: That is a subjective opinion which may or may not be shared by others. In any case, the purpose of the EIR process is to bring specific concerns to the attention of the reviewing agency. i -107- COMMENT 6D: "As I interpret the E.I.R. , the only way to resolve the ballfield issue is to down-size the complex and build the fields in the undeveloped area between Goldenwest Street and the existing park area." RESPONSE 6D: The ballfield complex will result in lighting impacts, noise impacts, tree impacts, traffic impacts, and biology impacts. Each significant impact identified may be mitigated to an extent. There is no disagreement that down sizing the complex will reduce the degree of various impacts. However, the decision-making body must determine the proper balance between meeting City objectives and individual or local concerns. COMMENT 6E: "On page 39 - 2.02.3 Mitigation Measures Huntington Lake: It is abso- lutely unnecessary to recommend construction of a pier into the lake. This recommendation has nothing to do with mitigation measures regarding Huntington Central Park. As a matter of improvement, appearance and aesthetic value, a pier out into the lake would detract from the beauty of the lake and park in general . Also, the pier would create a substan- tial addition to the park maintenance program as well as increasing the City liability." RESPONSE 6E: The pier into the Lake was recommended as part of the Lake Restoration Plan prepared by Harlann Glenn and Associates; December, 1980. COMMENT 6F: In the Appendix to this E.I.R. , it is indicated there will be an estimated revenue from the ballfields of $200,200. , or $548.49 per day continuously for 365 days per year. This estimate of revenue appears to be rather high and possibly unobtainable. Someone should verify this figure and the basis of the estimate." RESPONSE 6F: The revenue figure of $200,200 is in error and has been revised to $100,200. The revenue sources were obtained from the City's "Economic Feasibility Analysis" for Central Park. -108- COMMENT 6G: • "The E.I.R. , indicates that existing streets will accommodate the addi - tional traffic generated by the project. This assumption is simply not accurate and should be clarified and corrected with appropriate costs added to project funding needs." RESPONSE 6G: The comment is not accurate. The Draft EIR (Section 2.06.2, Page 56) indi - cates: "Golden West Street would be operating slightly beyond capacity and will require improvement to its ultimate cross section as a four-lane divided roadway in conjunction with park development. Other surrounding roadways are capable of accommodating additional generated traffic at the present time." This EIR does not address the capital improvement costs associated with the project. Such an assessment is not required by the California Environmental Quality Act. 7. BILL PATAPOFF CITY OF HUNTINGTON BEACH - JUNE 21, 1982 COMMENT 7A: "Page 33, the drainage patterns are incorrect." RESPOSNE 7A: Figure 11A was initially prepared with assistance from the City's Public Works Department. However, it has been corrected as indicated on the map attached to the comment. COMMENT 7B: "Page 56, paragraph 4 and page 60, paragraph 2.06.3 (1) a traffic signal has recently been constructed at the intersection of Goldenwest and Talbert." RESPONSE 7B: The paragraphs have been updated accordingly. -109- • COMMENT 7C: "Economic analysis in Appendix G does not list the required Public Works facilities (streets, sewer, storm drain, water mains), although the body of the report outlines their needs. Also the financing of the facilities needs to be decided." • RESPONSE 7C: See Response 6G. COMMENT 7D: "The E.I.R. does address the problems of the proposed ballfield lighting and how it will affect surrounding homes and 'residences. However, this E.I.R. does not address its (lighting) affect on Goldenwest Street. What type of buffer will be installed? Will a buffer be necessary?" • RESPONSE 7D: A landscape buffer is proposed along the Golden West Street frontage. The lighting affect on Golden West Street may at some points result in traffic . glare. However, mitigating measure lb (Section 2.04.3, P. 49) would reduce or eliminate glare to acceptable levels. COMMENT 7E: "The E.I.R. states that 'the roadways serving Central Park can accommodate the additional generated traffic. ' It further states that these roadways can accommodate this additional traffic as they exist today, except for Goldenwest Street. Other roadways need to be improved. One of the most vital roadways to this park, specifically Talbert Avenue, needs to be improved to its ultimate. This is going to be the park 's direct access from the east. Improvements will also be necessary on Ellis Avenue." RESPONSE 7E: The EIR, Section 2.06.3 (P. 60) recommends: 112. Improve Golden West Street as a four-lane divided roadway between Talbert and Slater in conjunction with development. 3. Construct all streets bordering the project to half-section widths adjacent to the project boundary in conjunction with development." An additional mitigation measure considering the improvement of Talbert Avenue to its ultimate design width has also been added on Page 61. • -110- COMMENT 7F: "On page 58, second paragraph, the last sentence stops in mid frame. The sentence needs to be completed." RESPONSE 7F: The complete statement could be found on Page 14 of the Traffic Study contained in the Appendix. The text has been corrected. The complete sentence on Page 58 now reads: "With the addition of the worst case traffic from the Planning Mode study area, Golden West between Talbert and Ellis will also operate at capa- city." COMMENT 7G: "Again, the E.I.R. states that there will be attempts to park on Golden- west or stop adjacent to the ballfield complex to load and unload passen- gers. Since 'No Stopping, ' 'No Standing, ' 'No Sitting' and 'No Parking' are going to be enforced, how will loading and unloading occur? Traffic Engineering staff feels that this subject should be addressed in this E.I.R. A possible solution would be an inlet street." RESPONSE 7G: A mitigation measure has been added to Section 2.06.3 (P. 61) which reads: "10. To accommodate the loading and unloading of passengers of the ball - field compelx and avoid on-street congestion therefrom the City should consider either an inlet street or a loading and unloading zone which is safely separated from traffic on Golden West Street." COMMENT 7H: "The matter of transit facilities has been unaddressed in this E.I.R. Since transit is only going to get bigger and better, these items (buses, zones, etc.) need to be included in this project." RESPONSE 7H: See Response 2A. -111- • 8.

Extending the hours to 10:30 p.m. would be in conflict with the ordinance. 9. CHARLES E.

Concerning subJect EIR, this department feels that the issue of possible expansion of the Police Firing Range should be addressed. At present,•.staff is negot.iating -a new lease for the range which includes reconstruction of the premises to allow the public to shoot an American Standard Course for handguns, construction of a multistoried stru.eture to include additional shooting stations, classrooms, publ.iz restaurant, sporting goods store and .gunsmith shop. Additionally., provision of security - should .be addressed. Staff working at the public landfill adjacent to: the range have re- ported several incidents of stray bullets from the range landing In their. immediate work area (see Jim Way, X-5287) . Also, the voice factor should be studied.

Pit being considered a "potential hazardous waste disposal site." Our abandoned site people did not have enough information to consider the Bruce Bros. Pit a potential hazardous waste site. This office's regular staff on March 10, 1980 inspected and sampled the soil in an area in which drilling muds were disposed of. The investigation was at the request of the City of Huntington Beach after the area had been cleaned-up. All samples upon analysis were determined to be non-hazardous. Additionally we have reviewed the Abondoned Site Groups file and found nothing in it to indicate that the Bruce Bros. Pit is a "potential -hazardous waste disposal site." Therefore, based upon the information available to this office, we do not consider the Bruce Bros. Pit a 'potentiE osal site." and norcemenecon Hazardous Waste Management Branch JAH:mw I -119- MURRAY STORM DIRECTOR,EMA ROBERT G.FISHER q v■ ,N� O C DIRECTOR OF PLANNING r LOCATION: 2 1 811 NORTH BROADWAY c SANTA ANA,CALIFORNIA • 5 3 / RANG MAILING ADDRESS: P.O.

Box 190 Huntington Beach, California 92648 • SUBJECT: DEIR for Huntington Central Park Expansion Dear Mr. Barnes, The Environmental Management Agency has reviewed the subject document and has + the following comments to relate: Air Quality o The EIR should show the derivation of usage rates for natural gas and electri- city given in the air quality appendix. o The motor vehicle emissions factors for total hydrocarbons should be 1.42 gm/mi in 1982 and 0.58 gm/mi in 1995. o Results of the CALINE3 computer runs should be reporduced in the air quality appendix. o Note for your information, that stability Class F is the worst case. Circulation o On page 53, last paragraph, the report states that the section of Talbert be- tween Edwards and Golden West is not shown in the City's Circulation Plan. It should be noted that there is an inconsistency between the City and County Mas- ter Plan of Arterial Highways (MPAH) ; the County plan shows Talbert continuous between Edwards and Golden West. O On page 59, last paragraph, the report discusses the potential future realign- ment of Talbert to connect to Ellis. The report should also discuss the poten- tial feasibility of connecting the discontinuous sections of Talbert via an alignment south of the lake. This connection, along with the Talbert Street bridge crossing the Santa Ana River, would provide through travel for.east/west • -120- Mr. Barnes File GSR2N027 Page 2 traffic. It should be noted that one reason for the projected heavy volumes and associated capacity problems on Warner, is the lack of parallel facilities serving destinations to the east (i.e. , South Coast Plaza) . The proposal to extend Talbert to Ellis will not alleviate this problem, since Ellis terminates at the river and traffic is redirected north, on to Euclid. o On page 60, Mitigation Measure section, the report should consider a south- bound right turn only lane on Golden West at the park entrance. This will relieve queuing problems during peak hour and special event uses of the park. Should you have any questions regarding this matter, contact Patricia Flores at 834-6246. Thank you for the opportunity to respond to this environmental document. When it becomes available, please forward a copy of the FEIR. V-ry truly yours, -6 C�Z;� Kenneth .

Engineering Planner Park, Tree & Landscape • Subject E.I .R Date June 14, 1982 Huntington Central Park The E. I .R. , is rather deceptive regarding size, location and disrup- tion to existing park caused by proposed ballfields . The proposed ballfield complex is the one feature of the Huntington Central Park improvement project that creates serious impacts to the entire area in and around Huntington Central Park. • None of the mitigating measures are substantial enough to satis- factorily solve the problems created by the size and anticipated use of the ballfields . As I interpret the E. I .R. , the only way to resolve the ballfield issue is to down-size the complex and build the fields in the undev: '-- oped area between Goldenwest Street and the existing park area. On page 39 - 2 . 02 . 3 Mitigation Measures Huntington Lake : It is absolutely unnecessary to recommend construction of a pier into the lake. This recommendation has nothing to do with mitigation mea- sures regarding Huntington Central Park. As a matter of improvement , • appearance and aesthetic value, a pier out into the lake would detract; from the beauty of the lake and park in general. Also, the pier would create a substantial addition to the park maintenance program as well as increasing the City liability. In the Appendix to this E. I .R. , it is indicated there will be an • estimated revenue from the ballfields of $2001,200 . 1. or $:,48. 49 per day continuously for 365 days per year. This estimate of revenue appears to be rather high and possibly unobtainable. Someone should verify this figure and the basis of the estimate . The E. I .R. , indicates that existing streets will accomodate the • additional traffic generated by the project . This assumption is simply not accurate and should be clarified and corrected with appropriate costs added to project funding needs .

We have reviewed the subject E.I.R. and have the following comments: _ 1. Page 33, the drainage patterns are incorrect. See attached ~' corrected flow patterns. 2. Page 56, paragraph 4 -and page 60, paragraph 2.06.3 (1) a traffic signal has recently been constructed at the inter- section of Goldenwest and Talbert. 3. Economic analysis in Appendix G does not list the required Public Works facilities (streets, sewer, storm drain, water mains) , although the body of the report outlines their needs. Also the financing of the facilities needs to be decided. 4. The E.I.R. does address the problems of the proposed ball- field lighting and how it will affect surrounding homes and residences. . However, this E.I.R. does not address its (lighting) affect on Goldenwest Street. What type of buffer will be installed? Will a buffer be necessary? 5. The E.I.R. states that "the roadways serving Central Park can t accommodate the additional generated traffic. " It further states that these roadways can accommodate this additional traffic as they exist today, except for Goldenwest Street. Other roadways need to be improved. One of the most vital roadways to this park, specifically Talbert Avenue, needs to be improved to its ultimate. This is going to be the park's direct access from the east. Improvements will also be necessary on Ellis Avenue. 6. On page 58, second paragraph, the last sentence stops in mid frame. The sentence needs to be completed. 7. Again, the E.I.R. states that there will be attempts to park on Goldenwest or stop adjacent to the ballfield complex to load and unload passengers. Since "No Stopping," "No Standing, " ,y "No Sitting" and "No Parking" are. going to be enforced, how will loading and unloading occur? Traffic Engineering staff feels that this subject should be addressed in this E.I.R. A possible solution would .be an inlet street. -123- A.- Memo to Jim Barnes Huntington Central Park Expansion June 21, 1982 Page 2 8. The matter of transit facilities has been unaddressed in this E.I.R. Since transit is only going to get bigger and better, these items (buses, zones, etc. ) need to be included in this project. 9.

X b. Does the project have the potential to achieve short-term, to the disadvantage of long-term, environmental goals? (A short- term impact on the environment is one which occurs in a relatively brief, definitive period of time while long-term impacts will endure well into the future.) X c. Does the project have impacts which are individually limited, but cumulatively con- siderable? (A project may impact on two or more separate resources where the impact on each resource is relatively small, but where the effect of the total of those Impacts on the environment is significant.) X d. Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly? X III. Discussion of Environmental Evaluation. i The following comments further describe project characteristics for which "yes" or "maybe" answers were represented above. I.B. Construction on the subject site may result in removal and over- covering of the soil. C. Construction on the subject site may result in'alteration of topo- graphy. A significant amount of fill may be necessary to develop the active recreational areas. G. The City-wide Geologic Hazard Study prepared by Leighton/Yen and Associates indicates that the Bolsa-Fairview fault traverses the southwest portion of the site. 2.A. With an expected increase in automobile traffic to the park, there will be a subsequent increase in emissions from cars. A cumulative assessment of air quality impacts should be prepared taking into account existing air quality standards. B. The former county landfill emits methane gas which could produce ob- jectionable odors if disturbed. 3.B. Projects which are eventually constructed on the site may substanti- ally decrease water absorption rates and increase runoff. Some areas are at lower elevations than other areas and may experience poor drainage. E. Discharges from development and equestrian uses may alter surface water quality within the park lake system. • 4.A. Construction of recreational uses (especially in and around ball- field) will result in displacemment of existing trees and shrubs. C. Supplementary landscaping for buffer and aesthetic purposes is pro- posed. 5.A. Some species of animal may be displaced from the park while others will relocate to new niches within the park. 6.A. Increased automobile traffic and short-term construction will result In increased noise levels on the adjacent streets. Noise from acti- vity on the ballf ield complex may impact residential areas. 7.A. Lighting for the ballfield complex may impact adjacent residential areas. 8.A. The proposed land use changes will result in a substantial increase in intensity of use and character of the park (from passive to • active). 10.A. A potential risk due to the release of methane gas or other hazard- ous substances in the landfill area may pose a hazard to users of the park. 13.A, Projects eventually constructed on the site will result in a sub- B, C, stantial amount of automobile traffic which may significantly D, F. impact the City's circulation system. Based on the number of additional trips generated by projects which will ultimately de- velop on the sites, a general assessment of impacts on street and intersection capacities should be presented. Further, given the level of recreational activity, an assessment should also be made on the adequacy of the parking facilities. 14.A. The potential increases in intensity of use resulting from projects B, D, which will be developed on the site may result in significant de- E, F. mand for additional public services. A general assessment of con- cerns of potentially affected agencies and departments (i.e. , fire, police, public works) should be determined and presented in the EIR. 16.A The potential increases in intensity of use resulting from projects -F. which will be developed on the site may result in significant demand for the expansion of existing utility systems. A general assess- ment of the concerns of the potentially affected agencies should be determined and presented in the EIR. 18. The character of the park may change from passive to active uses, thus altering the aesthetic quality. �. 19. New recreational opportunities will be offered by the proposed changes within the park. 20. The proposed land use change may alter archaelogic sites in the southwest portion of the park. I r IV - DETERMINATION On the basis of this initial evaluation: find that the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared. I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because the mitigation measures described on an attached sheet have been added to the project. A NEGATIVE DECLARATION WILL BE PREPARED. I find the proposed project MAY have a significant effect on the environ- ment, and an ENVIRONMENTAL IMPACT REPORT is required.

The project is located in the City of Huntington Beach and is bounded by Golden West, Ellis, Slater and Gothard.. The overall site includes approxi- mately 279 acres. Anticipated park uses includes six ball fields , an equestrian center, a YMCA site, expansion of an existing shooting • range , food facilities and a 2200 car parking lot. The traffic report contains documentation of existing traffic conditions, traffic generated by the project, distribution of the project traffic to roads outside the project, and an analy- sis of future traffic conditions. Each of these topics is con- tained in a separate section of the report. The 'first section is "Findings" , and subsequent sections expand upon the findings. In this way, information on any particular aspect of the study can be easily located by the reader. Although this is a technical report, every effort has been made • to write the report clearly and concisely. To assist the reader with those terms unique to transportation engineering, a glossary of terms is provided in Appendix A. • • 1. Findings This section summarizes the existing traffic conditions, project 0 traffic impacts, future traffic conditions, and the suggested mitigation measures. Existing Traffic Conditions 1. Existing land uses on the Central Park project site include 0 existing park uses, a public library, equestrian facilities, a shooting range and a recreational lake. 2. Although the existing circulation network in the study is generally constructed, many of the roadways are not con- structed to their full ultimate cross-sections. 3. The existing roadways in the vicinity of the project site are generally operating below capacity except for Golden West Street between Talbert Avenue and Slater Avenue which is approaching existing capacity. 4. Although parking is provided for existing park and library uses, parking demand frequently exceeds the number of avail- able parking spaces. Future Traffic Conditions 1. Proposed land uses for Central Park project includes the con- struction of a ballfield complex, a YMCA and restaurant facilities, relocation of the equestrian center, expansion of shooting range, aeration of lakes to provide for fishing, and the construction of a 2,200 space parking lot. . 2. Full development of the Central Park project will result in the generation of 5,680 vehicle trips on an average weekday. 3. Alternative land uses analyzed for the 25 acre Planning Mode site adjacent to the park project include garden offices, residential development, a recreational vehicle camp area, and a commercial nursery and tree farm. 4. Daily traffic generation for the land use alternatives in the Planning Mode area ranges between 460 and 4, 800 vehicle trips daily. • 5. For existing plus project traffic conditions, Golden West between Talbert and Slater will exceed the capacity of the existing roadway. 2 i • • 6. For future traffic conditions, the .regional roadways of Beach Boulevard and Warner Avenue are projected to exceed capacity. For worst case conditions assuming the addition of project traffic to future traffic projections, Golden West between Warner and Talbert is approaching the capacity of full ultimate roadway improvements. 7. General traffic model results indicate that it is preferable that land uses which are primarily local in nature, such as the proposed Central Park project, will result in less over- all traffic impacts than will uses generating regional type trips, such as the garden office project on the Planning Mode site. 8. The proposed project parking facilities will adequately service future parking demand. • Mitigation Measures 1. Install a traffic signal at Golden West and Talbert based on traffic volume signal warrant and to provide for safe pedestrian crossings of Golden West from proposed parking facilities . 2. Improve Golden West as -a four lane divided roadway between Talbert and Slater in conjunction with development. 3. Construct all streets bordering the project to half-section • widths adjacent to the project boundary in conjunction with development. 4. Design bicycle and pedestrian circulation facilities to create crossings of major streets at signalized intersection locations. • 5. Construct pedestrian trails internal to the park system with all weather surfaces and of sufficient width to accommodate emergency vehicle access internal to the park area. Trail access locations should be controlled with locked barriers to restrict non-emergency/maintenance vehicle access to interior park locations. 6. "No Stopping" signs should be posted on Golden West adjacent to the ballfield complex to eliminate the loading and unloading of passengers from vehicles on Golden West and ballfield users attempting to park on Golden West. • 7. Future potential equestrian crossing lodations of arterials should be minimized and crossing locations should be posted and monitored by the City -to insure crossing safety. • 3 • 2. Project Description Project Location The project is located in the City of Huntington Beach and is bounded by Golden West, Ellis, Slater and Gothard. The Planning Mode study area site is located on Golden West between Ellis and Talbert. Proposed Project The area designated Huntington Central Park comprises a gross area of 297 acres in addition to a potential expansion area of 30 additional acres. Proposed land use improvements within the park are discussed further below and their approximate locations are shown in Figure 1. 1.. Ballfield Com lex - The ballfield complex is proposed to in- clude six lighted softball diamonds with accompanying blea- chers, dugouts, concessions , restrooms , and equipment storage buildings. Six sets of bleachers will provide a total seat- ing capacity for approximately 600 spectators. Softball fields are also designed to double for use in football, soccer, or rugby competition. 2. Equestrian Center - The equestrian center is to provide stable facilities for approximately 250 horses. Also included in the equestrian center is a practice ring, paddocks, a central building, and a show ring/rodeo area with bleachers for spectators. 3. Golden West Parkin - Approximately 2,200 parking spaces will e constructed on a turf or gravel surface and will be located southerly of the existing library and east of Golden West. Parking in the Golden West lot will service adjacent restau- rants, the existing library, and the ballfield complex. 4. Resident Caretaker - A single mobile home slab is proposed for construction to accommodate a resident caretaker for the park area. 5. Shooting Range Expansion - Expansion of the existing shooting range will prove a or additional shooting stations and a gun shop on the 6 acre site. 6. Restaurant - Approximately 3 acres are set aside to con- struct and operate restaurant facilities . 4 7. YMCA - The construction of a YMCA facility on a 5.5 acre parcel is proposed and would include 340 paved parking . spaces for the site. • 6. Sully Miller Fishin Lake - Sully Miller Lake is to be upgraded to. accommo ate ishing activities and landscapinq is to be provided. 9. ' Huntington Lake' Aeration System - The construction of an aeration system and access pier to enable the lake to be • stocked with fish is proposed. 10. Sully Miller Lake Aeration System - Construction of an aeration system to enable the lake to be stocked with fish is proposed. • 11. Equestrian Center Parkin Lot - Paved parking facilities for approximately 200 vehicles is to be provided for equestrian center uses. 12. Passive Park Area and Equestrian Trails - Supplementary park areas throughout the park are to a andscaped for general passive use. An equestrian trail system throughout the park will also be developed. 13. "Planning Mode" - Additionally, 25 acres currently under private ownership has been designated as "Planning Mode" to allow the City to investigate site opportunities. The four • alternative land uses which were considered for the Planning Mode study are as follows: a. Garden offices with an adjoining restaurant b. Estate residential • c. A recreational vehicle camp d. A commercial nursery/tree farm • • 5 • L ji �I f , �u. I Iww iv- T t ts ola l�� au'�.-.,��_i�R.. �b� � L- -�,yy�.;ma's:` •� 1 Rj ell c r%3 3. Existing Traffic Conditions This section discusses the surrounding street system,. daily traffic volumes and the existing circulation plan. Figures 2 and 3 illustrate the existing traffic conditions in the study area. Surrounding Street System Local and regional access are provided for the project from the following roadways . Golden West Street. Golden West is an existing north/south roadway in the C1'ty_oT Huntington Beach. Golden West divides the Central Park site and is presently stripped as a four lane undivid- ed roadway adjacent to the site. Portions of Golden West are con- structed to the full ultimate primary roadway cross-section with curbs, gutters and street lights, but adjacent to the site, existing Golden West is constructed with only graded shoulders. • Golden West has a existing on-street bicycle route adjacent to the site and is also an existing OCTD Bus Route. It now has no median by the park. Talbert Avenue. Talbert Avenue is an existing two lane un- divi3ea roadway which divides proposed park uses from existing • Central Golden West through the City of Huntington Beach. As it is shown on the City's Circulation Plan of Streets and Highways, Talbert is designated to be ultimately constructed to secondary roadway standards between Golden West and Gothard and primary roadway standards east of Gothard. In addition, a discontinuous portion of Talbert Avenue is constructed west of Edwards but it • does not directly align with Talbert to the east of Golden West. The two sections of Talbert are not shown as connecting on the City of Huntington Beach Circulation Plan. Ellis Avenue. Ellis Avenue is an existing east/west roadway located along t e southern boundary of the project site. Ellis is • presently constructed as a two lane roadway with graded shoulders between Edwards and Gothard. Ellis is designated to be ultimately constructed to primary roadway standards between Gothard and Edwards and is shown as a proposed primary arterial connecting to Bolsa Chica to the west of Edwards. • • 6 • • Number of Through Travel Lanes and Existing Intersection Controls The number of through travel lanes and existing intersection con- trols for existing roadways in the study area are shown in Figure 2. • Existing Traffic Volumes The most recent daily traffic volume counts for roadways in the study area are shown in Figure 3. Traffic volumes counts were obtained from the City of Huntington Beach, the County of Orange, and CalTrans. Traffic volumes on State Highways are 1980 traffic volumes, City of Huntington Beach average daily traffic volumes are for 1978 conditions, and County of Orange Traffic Flow volumes are dated for 1981 conditions . Existing Daily Volume to Capacity Ratios Roadway capacity is generally defined as the number of vehicles which can reasonably be expected to pass over a given section of a 'road in a given time period. Daily roadway capacities reflect estimates of the amount of daily traffic which will result in peak hour traffic volumes equal to the maximum desirable capacity for each roadway type. Daily roadway capacities for Level of • Service D conditions on roadways in the study are estimated to be 12, 500 vehicles per day for two lane undivided roadways, 22 ,000 vehicles per day for four lane undivided roadways , 33,000 vehicles per day for four lane divided roadways, and 49, 500 vehicles per day for six lane divided roadways . It should be noted that the daily capacities estimated are lower than can actually be achieved by approximately ten percent. This is also reflected in the Level of Service D notation which is typically used as the design standard for urban conditions . By dividing existing traffic volumes by daily roadway capacity for existing facilities, existing daily volume to capacity ratios have been calculated and are shown in Figure 4 . Review of Figure 4 indicates that Golden West between Talbert and Slater is currently approaching capacity for the existing roadway geometrics adjacent to the project site.

Traffic Generation and Distributions To estimate project-related traffic volumes at various points on the street network, a three step process is utilized. First, the traffic which will be generated by future development is de- termined. Secondly, the traffic volumes are geographically distributed to major attractions of trips, such as employment centers, commercial developments, and residential developments. Finally, the trips are assigned to specific roadways and the future traffic volumes are determined on a route-by-route basis. Traffic Generation The traffic generated by the land uses is determined by multiplying an appropriate trip generation rate by the quantity of land use. Trip generation rates are expressed in terms of trip ends per per- son, trip ends per employee, trip ends per acre, trip ends per • dwelling, or trip ends per thousand square feet of floor space. If a particular land use generates six outbound trips per acre in the morning peak hour, then six vehicles are expected to leave the •site in the morning peak hour for each acre of development. Significant research efforts have been made by CalTrans, the • Institute of Transportation Engineers, Kunzman Associates, and others to establish the correlation between trips and land use. From this body of information, trip generation rates can be esti- mated with reasonable accuracy for various land uses. Trip gene- ration rates are predicated on the assumption that energy costs , the availability of roadway capacity, the availability of vehicles • to drive, and our life styles remain similar to what we know today. A major change in . these variables may affect trip generation rates. Trip generation rates were determined for average daily .traffic and daily weekend traffic conditions. By multiplying the traffic generation rates by the quantity of land uses , the • traffic volumes are determined. Table l exhibits the traffic generation rates and the daily traffic volumes by project land use. Traffic Distribution and Assignment • Traffic distribution is the determination of the directional orientation of traffic. It is based on the geographical location of residential uses along with commercial, and other business opportunities. 8 • Traffic assignment is the determination of which specific route traffic will use once the generalized traffic distribution is determined. The basic factors affecting route selection are minimum time path and minimum distance path. Quite often the minimum time and distance paths are one in the same. When the two paths are different, the minimum time path will usually take precedence, assuming all other considerations are equal. Other considerations might be the aesthetic quality of alternate routes, grades, and so forth. It should be noted that the minimal time path is cognizant of congestion. As a roadway's volume approaches capacity, ' operating speeds decrease. Ultimately, congestion on the shortest distance path will decrease the speed until an al- ternate path has a shorter time path, then traffic will divert to the shorter time path. Based on the types of land uses proposed in the Central Park plan and the land uses identified in the City of Huntington Beach General Plan, the generalized traffic distribution for the study area is shown in Figure 6. 9 Table 1 TRIP GENERATION Daily Daily Weekend Weekend Generation Trips Generation Daily Trips Land Use Quantity Rate Generated Rate Generated Central Park Project Ballfield Complex 6 fields 70/Diamd 420 100/Diamd 600 Equestrian Center 100/Units 100 300/Unit 300 Resident Caretaker 1 DU 7/DU 7 7/DU 7 Shooting Range 6 AC 77/AC 463 128/AC , 768 Restaurant Complex 2 Units 2,100/Unit 4,200 3,150/Unit 6,300 YMCA 5.5 AC 90/AC 495 110/AC 605 Subtotal 5,680 8,580 Planning Mode Alternatives 1.

Existing Plus Project Traffic Conditions • Once the project-related traffic is assigned to the existing street network and added to existing volumes, the traffic impact can be assessed. Figure 7 illustrates the existing plus project traffic conditions. Traffic Volumes Upon completion of the Central Park land uses, the expected daily two-way traffic volumes are as illustrated in Figure 7. Volume To Capacity Ratios Based on the capacities of the existing roadway sections, the volume to capacity ratios for the existing plus Central Park pro- ject condition has been calculated and is also shown in Figure 7 . For future conditions with project traffic, Golden West between Talbert and Slater will exceed existing capacity. The improvement of Golden West to its ultimate cross-section as a .four lane divided roadway will result in a volume to capacity ratio of 70 percent of capacity. Therefore, based on needed capacity, the improvement of Golden West should occur in conjunction with park development. Signal Warrants Once traffic volumes are determined, the next step is to determine whether the Golden West and Talbert intersection warrants a traffic signal. Examination of Table 2 , signal volume warrants, and the existing plus project traffic daily volumes shown in Figure 7 reveals that a signal at Golden West and Talbert is ex- pected to be warranted with the construction of the project. Existing Plus Project Plus Planning Mode Alternatives Future traffic volumes based on existing traffic conditions and the completion of the project and the construction on the planning mode is shown in Figure 6. Future daily traffic volumes are shown as a range reflecting the range in trips generated by the planning mode alternatives. With the planning mode alternatives, the traffic volumes increase most significantly on Golden West. Golden West between Talbert Avenue and Slater will need to be modified to a four lane divided roadway based on roadway capacity. Golden West between Ellis and Talbert will also be approaching capacity and it would be desir- able for it to be widened to a four lane divided roadway in con- junction with planning mode alternatives development. 11 Table 2 SIGNAL VOLUME WARRANTS • Warrant Minimum Volumes Entering Minimum Vehicular Interruption of Intersection Volume Continuous Warrant Traffic Warrant Urban* Rural Urban* Rural Major Street (Add Both Approaches) 1 lane approaches Daily Volume 8,000 5,600 12,000 8,400 Eight Highest Hours Volume 500 350 750 525 Peak Hour Volume 800 560 1,200 840 2 or more lane approaches Daily Volume 9,600 6,720 14,400 10,800 Eight Highest Hours Volume 600 420 900 630 Peak Hour Volume 960 672 1,440 1,080 Minor Street Hig est Vo ume Approach) 1 lane approaches Daily Volume 2,400 1,680 1,200 850 Eight Highest Hours Volume 150 105 75 53 Peak Hour Volume 240 168 120 85 2 or more lane approaches Daily Volume 3,200 2,240 1,600 1,120 Eight Highest Hours Volume 200 140 100 70 Peak Hour Volume 320 224 160 112 * Use rural warrant if speed is greater than 40 miles per hour on any leg Source: CalTrans and Federal Highway Administration adopted signal warrants 12 • Figure 7 • Existing Plus Piroject Traffic Volumes And Volume to Capacity Ratios N 3 N U; t t 20-.61 W 24- 73 25-.76 25-.76 °w Warner Avenue 00 m m m N 11 .33 10- .30 8-.24 Slater Avenue 0 N C f in tC !7 N 6-.27 .

Future Traffic Conditions Traffic volumes forecasts for 1995 conditions have been obtained and, are discussed further below. Future Average Daily Traffic Volumes Average daily traffic volumes for future 1995 conditions are shown in Figure 9. 1995 daily traffic volumes are from the City of Huntington Beach Traffic Model which was run and tested by the County of Orange ERA in the Winter of 1981. EMA staff said that the land uses assumed are for the existing General Plan of the City of Huntington Beach. S' Future Conditions Volume to Capacity Ratios Based on the future 1995 traffic volumes, volume to capacity ratios have been calculated and are shown in Figure 9. Future conditions volume-to-capacity ratios have been calculated based i on full buildout of the City of Huntington Beach's Circulation Element. For 1995 conditions, the regional roadways of Beach Boulevard and Warner Avenue are projected 'to exceed planned capacity. In addition, Golden West between Warner and Slater is also projected to exceed capacity, and Golden West between Slater and Ellis is shown to be approaching the capacity of full ultimate roadway improvements. Future Traffic Conditions With The Central Park Project and Planning Mode A ternatives Future 1995 average daily traffic volumes shown in Figure 9 have been identified by EMA staff as reflecting the existing General Plan for the City of Huntington Beach. However, as coding for individual zones in such traffic models represents an aggregate of land use in a particular zone, and is typically tabulated in terms of employees, the specific land use assumptions for the Central Park project area and the Planning Mode study area, could not be identified. To provide for a worst case analysis, it has been assumed that neither the proposed Central Park project, nor land use alternatives for the Planning Mode study area have been included in future 1995 traffic model volume projections . Based on this assumption, traffic from the Central Park project and the Planning Mode study area have been added to 1995 traffic model projections. Average daily 1995 traffic volumes for only the Central Park project impacts are shown in Figure 10 , and traf- fic volumes for both the Central Park project and the worst case Planning Mode study area alternative are shown in Figure 11. Also shown in Figures 10 and 11 are the future volume to capa- city ratios for the two alternatives. 13 Based on future conditions volume to capacity ratios, Beach, Warner, and Golden West north of Talbert are projected to exceed capacity with the proposed Central Park project. With the addition of the worst case traffic from the Planning Mode study area, Golden West between Talbert and Ellis will also operate at capacity. Although conclusions are based on worst case assumptions and are without the specific knowledge of all land use assumptions in the traffic model for particular traffic zones, general traffic model results indicate that it is preferable that land uses which are primarily local in nature, such as the proposed Central Park project, will result in less overall traffic im- pacts than will uses generating regional type trips , such as the garden office project on the Planning Mode site.

Other Traffic Considerations Vehicle Parking Demand Vehicle parking demand for each of the proposed parking lots has been estimated and is shown in Table 3. Parking demand esti- mates are based on parking demand studies performed by Kunzman Associates, a review of existing parking codes, and a literature search of parking demand at inventoried park facilities. Based on the estimated parking demand, the proposed number of parking spaces is anticipated to be adequate for future traffic conditions. Golden West Parking Area Access Four driveway locations are proposed for the 2,200 vehicle parking lot. Based on a review of park locations , a maximum of 75 percent of accumulated parking demand was observed to egress a site during a peak one hour period. Based on the distribution of traffic from the site, all driveways from the site are anticipated to be capable of adequately servicing peak period egress demand. Some short term queueing at the Golden West and Talbert intersection may occur, however, the intersection should be capable of servicing vehicles with a minimum of vehicle delay to egressing traffic and traffic on the arterials. Pedestrian Access With the proposed location of the Golden West parking lot, pedes- trians will be required to cross Golden West for access to the ballfield complex and other portions of the park. Pedestrians will also be required to cross Talbert Avenue for access to the existing library and the existing portion of the park. Pedestrian crossing facilities should be' located to create crossings of major streets at signalized intersection locations. Pedestrian crossing indi- cators should be installed in conjunction with the installation of the traffic signal at Golden West and Talbert and pedestrian walk- ways should be oriented to provide for pedestrian crossings at this location. Due to the remote location of proposed parking to the ballfield complex, it is of conern that some ballfield users will attempt to park on Golden West or will stop adjacent to the ballfield complex to load and unload passengers. City roadway standards do' not provide for on-street parking on arterials , and the stopping of vehicles to load and unload passengers is antici- pated to result in a significant -safety hazard and create con- gestion on Golden West. "No Stopping" signs should be posted on Golden West adjacent to the ballfield complex to eliminate the loading and unloading of passengers from vehicles on Golden West and ballfield users attempting to park on Golden West. 15 � i Emergency Vehicle Access For existing and proposed portions of Central Park, the park is designed with only remote parking locations and vehicle access is not permitted interior to the park. To provide for emergency and maintenance vehicles access interior to the park, pedestrian trails should be constructed as all weather surface trail and be of sufficient width to accommodate emer- gency and maintenance vehicles. Trail access locations should be controlled with locked barriers to restrict private vehicles from driving on these trails in the parks interior . Equestrian Crossings • With the provision of an equestrian facility in the park plan, there is the potential- for equestrian users to attempt to travel along and across adjacent arterials. To provide for the maximum safety of the horses, the riders, and the driving public, it is highly desirable for equestrian trails to be identified which are internal to the park area and do not require any at-grade cros- sings of the adjacent arterials. In any event, the at-grade crossing of arterials should be minimized and should only occur at prescribed locations where adequate visibility is feasible and lower traffic volumes exist: Equestrian crossing locations should be posted to alert motorists, and the locations should be monitored by the City of Huntington Beach to insure crossing safety. • Future Realignment of Ellis To Connect With Talbert During the planning process, the realignment of Ellis Avenue west of Golden West to connect with existing Talbert west of Edwards has been proposed. The proposed realignment would divide existing park properties and result in an isolated site south of the re- aligned Ellis. The proposed realignment is anticipated to result in increased pedestrian and equestrian crossings for site access . Special treatment of parking for the isolated site would probably need to be considered. In addition, the realignment would signi- ficantly reduce the extent to which equestrian trails could be provided which would not cross arterial highways. The proposed realignment is not shown on the existing City of Huntington Beach Circulation Plan and would require the modification of that plan. Vehicle Miles of Travel i Based on information derived from the Los Angeles Regional Transportation Study (LARTS) , average one-way trip lengths by land use have been identified and are shown in Table 4 , Based on the average daily trips generated by the Central Park Project and Planning Mode study area alternatives, the vehicle miles of travel for the proposed uses have been calculated and are shown in Table 5. 16 • Table 3 PARKING ADEQUACY • Estimatedl Parking Design Parking Spaces Lot Location Demand Provided Golden West Parking Restaurants 110 - Shooting Range 100 - General Park Uses 890 - Ballfield Complex 360 - Total 1,460 2,200 YMCA 300 340 Equestrian Center 60 200 • 1Parking demand is estimated for typical design conditions and does not include additional demand for special events.

Recent activities .in the area appear to be primarily related to oil field activities with a sand .pit also located within the area. Some property development has also occurred, primarily in the southern areas. • The park area was surveyed in 1972 as part of the large resources survey conducted by Archaeological Research, Incorpo- rated (ARI) for the City of Huntington Beach .(ARI 1973) . As a • result of this survey, two archaeological sites were re-checked and one potential historical site was defined within the area delineated for. the park. No paleontological locales were reported in this area. • HISTORICAL RESOURCES • The potential historical site was not positively identified, but was determined to be near the intersection of Gothard Street and Slater Avenue within the limits of the park boundaries (ARI 1973:29) . The site would consist of the remains of the Marilla • Adobe and would date to ca. 1800 A.D. If located, it would be significant in providing data pertinent to research in four periods of early California history: 1) the initial contact period between Anglos and Native Americans, .2) the Spanish • Rancho period, 3) the Mexican State, and 4) the transition to California statehood. • • -3- Recommendations : It was recommended by ARI that attempts be made to locate this potentially significant site. It is possible that one of the older buildings now in existince in the .park area consists of adobe covered by wood. This could, therefore, be the remains of' the Marilla'Adobe (Helen Smith, per communication) . Prior to the removal of existing structures, they should be checked by a qualified historian to ascertain their historical potential. In the event that the adobe is not located through the examination of the older buildings, a monitor should be present during earth moving activities in case artifacts associated with this historic structure are uncovered. If historic remains are encountered, grading should be diverted until an evaluation can be made. PREHISTORIC RESOURCES Two prehistoric sites have been located within the park's boundaries : CA-Ora-142 and the northeastern portion of Ora-82. Ora-142 was located on a knoll directly northwest of the inter- section of Talbert Street and Golden West . Street. Ora-32 was located along the bluff edge between Ellis Avenue and Taylor Drive with Edwards Street bisecting the site. • CA-Ora-142 Ora-142 was field checked by ARI in 1972. According to the survey report, the Division of Highways used the site area as a _ borrow site, thus , almost totally removing the deposit (ARI 1973 : 19) . According to the updated site form, only one edge of the midden remains with -scattered shell and flakes the only surface •' indicators as to the prior location of the site. -4- ' • Recommendations : • Since the major portion of this site no longer exists, the archaeological research potential of this area is low. Some undisturbed portions of the site may remain, however, covered by bulldozer back dirt. If such deposits are- encountered during • earth moving activities, the activities should be diverted and a qualified archaeologist should be retained to determine the significance of any remaining midden deposit. • CA-Ora-82 - Previous Investigations : • The northeastern portion of this site extends into the project area. This portion was excavated by the. Pacific Coast Archaeological Society (PCAS) under the direction of Lee Savio (Brown) with 'the aid of the field classes from Saddleback Community College and Santa Ana Community College. . The project was started because the widening of Edwards Street followed by heavy rains resulted in considerable erosion along the road right-of-way, which exposed numerous artifacts and human skele- tal material. The primary purpose of the excavations was an attempt to preserve, through controlled excavations, that area of the site which appeared to be in danger of being destroyed through natural forces aggravated by the road widening. Thirty-seven 2 m2 units were excavated in the area of the site contiguous to the road and east of the road. In all , • eight (and possibly nine)- burials were salvaged. In addition, an extensive ph testing and mapping project Was completed by John Maguire and Ed Lyons of PCAS which defined the perimeters . of the site (Pat Hammond, PCAS; Frank Chapel, PCAS; personal communication) . -5- Site Significance: The excavations which have been completed on the portion of Ora-82 within the park boundaries are sufficient to define this area as a prehistorical burial ground. Although the limits of the .burial ground within the site area have not been defined, those portions of the site which functioned as living areas are also important to future research into the life style of the prehis- toric peoples who inhabited the area. The site has been . radio- carbon dated to approximately 3000 B.C. and, consequently, can provide valuable data pertinent to research geared toward the earlier occupations of the Huntington Beach Mesa area. Because this area has been so defined, it has become an easy target for pot-hunters. During a field reconnaissance by Frank Chapel in 1979, numerous fresh holes were observed in the site area. It is assumed that the area continues to be dug by unau- thorized persons for non-scientific purposes. Recommendations: It is recommended that the portion of Ora-82 within the park . area be fenced to discourage pot-hunters and their destructive efforts. Preservation would also include, excluding the area from construction of irrigation' pipes, equestrian trails, sidewalks, etc. It is also recommended that any improvements to or along Edwards Street be monitored by a qualified archaeologist. PALEONTOLOGY According to the ARI report (1973) , no known paleontological locations are within the park limits. However, since the park is located on the Huntington Beach 2iesa, it is possible that vertebrate faunal materials related to the Pleistocene epoch could be uncovered. -6- • Recommendations: It was noted by ARI (1973 :3) .that earth moving activities .which excavated over five feet (in depth) of dirt had the greatest potential for uncovering paleontological deposits. In the event that such deposits are uncovered, a qualified paleon- tologist should be retained to inspect the deposit and remove significant fossils. SUMMARY OF RECOM ENDATIONS Historical - An attempt should be made to determine if any of the existing structures in the park area are the Marilla Adobe. If this approach fails , then any historic deposits encountered . during earth-moving activities should be inspected by a historian to determine possible relationships to the adobe. Archaeological - That portion of Ora-82 located within the park limits has been defined as containing a prehistorical burial ground dating to ca. 3000 B.C. Ora-82 should be fenced and pre- served intact. Since Ora-142 was destroyed in 1972, no investi- gations are recommended. However, if undisturbed midden areas are uncovered in the vicinity of the site during earth moving operations, a qualified archaeologist should be retained to determine the .deposit' s significance. (Figure 2) . Paleontology - Potentially, earth-moving . operations at a depth of five feet could encounter paleontologically significant fossils. In the event that fossils are encountered, a qualified paleontologist should be retained to determine their signifi- cance and remove any important remains. -7- • � (j �_ ..J• �J'• .t.ark•Vte� N 0.—.� C Trailer p� --,�.••. .al t VA i I •_� i y ....•»» Par_ - ' Sty rRIEs Ar l'OQ c� I�ry \I i i1.1.�.=r� (.

By 1995, motor vehicle emission controls will reduce the air pollutant emissions associated with the project to 0.205 tons per day. 7) Receptors 150 feet from the roadways serving project traffic will experience an insignificant increase (0.05 ppm) in car- bon monoxide concentrations over 8-hour or 12-hour averaging periods after the park expansion is complete. 8) The project will not significantly degrade air quality on a local or regional basis. i • 2.0 EXISTING AMBIENT AIR QUALITY 2. 1 Climate and Meteorology • . The study area has a mediterranean climate with warm summers and mild winters. The average daily temperature during the winter months is 52 degrees. During the summer months, temperatures average 68 degrees. Medium humidity and daily fogs are also characteristic of this shoreline. The land/sea breeze is the primary factor affecting the region's mild climate. The daytime winds are sea breezes predominantly from the southwest which flow at 5 to 7 miles per hour. During the night, the winds usually reverse direction. These land breezes flow from the northeast at 1 to 2 miles per hour. During the fall and winter months the study area is subject to moderate • and strong Santa Ana winds. The average precipitation is approx- imately 12 inches annually within the project vicinity. Rain falls in Orange County an average of 35 days per year. 2.2 Ambient Air Quality The South Coast Air Quality Management District (SCAQMD) main- tains ambient air quality monitoring stations at numerous loca- tions, the closest of which are Los Alamitos and Costa Mesa. Ambient air quality data from these stations is given in terms of state standards which were adopted to protect public health with a margin of safety. In addition, California has adopted. episode criteria for oxidant, carbon monoxide and sulfur dioxide. Epi- sode criteria represent short-term exposures at concentrations which actually threaten public health. Air quality trends have developed at the Costa Mesa and Los Alamitos air quality monitoring stations between 1978 and 1980. • These trends are discussed below. The Appendix of this report provides the ambient air quality data in terms of state stan- dards. Also included is a comparison of state standards and emergency criteria. From this information, it can be seen that only sulfur dioxide has not equalled or, exceeded the relevant 1- hour and 24-hour state standards. All other major pollutants monitored have exceeded the standards at the two nearby stations. Of all the pollutants, total suspended particulates equal or exceed the California standard most often. Suspended particu- lates exceeded the California 24-hour standard of 100 micrograms per cubic meter on 46 percent and 30 percent of the days moni- tored at the .Los Alamitos and Costa Mesa stations, respectively. Between 1978 and 1980, 19 percent of the months at the Costa Mesa station exceeded the lead standard (1.5 micrograms per cubic meter over a 30-day averaging time) . The lead standard was exceeded at Los Alamitos during 22 percent of the months. How- ever, due to the phasing out of lead as a motor vehicle fuel • additive, this condition is expected to improve. Oxidants are also of concern. The California one-hour standard 2 • (0. 10 pm) was equalled or exceeded on 16 percent of the days monitored at Los Alamitos and 9 percent of the days monitored at Costa Mesa. Ten Stage One episodes for ozone were called between 1978 and 1980 at the Los Alamitos monitoring station. Five were called in 1978, 2 in 1979 and 3 in 1980. No Stage Two episodes have been called at Los Alamitos. Four Stage One episodes, but no Stage Two episodes for ozone .were called between 1978 and 1980 at the Costa Mesa monitoring station. Three Stage One episodes were called in 1978 and one in 1979. At Costa Mesa, the state standard for carbon monoxide (10 ppm - 12-hour avg. ) was violated on ten days, during the last three years, but the one-hour standard was not exceeded. Carbon monox- ide levels in Los Alamitos were not measured. Carbon monoxide episode levels have not been attained at either station. Although nitrogen dioxide was not measured at Los Alamitos, it did exceed the one-hour standard on 1 percent of the days moni- tored at Costa Mesa. The California standard for nitrogen diox- ide is .25 ppm for one hour. 2.3 Effects of Pollutants on Receptors Demonstrated effects of air contaminants on health and vegetation are briefly discussed below. Oxidants at high enough concentra- tions can cause eye irritation; aggravate .respiratory disease; suppress the body's capacity to fight infection; impair athletes' performance and cause growth retardation in sensitive trees. Hydrocarbons in the presence of other primary pollutants (partic- ularly oxides of nitrogen) lead to the formation of oxidants. Hydrocarbons also damage plants by inhibiting growth and causing flowers and leaves to fall . Carbon monoxide is essentially colorless, odorless and toxic to humans. It enters the blood stream and interferes with the transfer of fresh oxygen, thereby depriving sensitive tissues in the heart and brain of oxygen. At high enough concentrations it can impair visual function, psychomotor performance and time discrimination. Nitrogen dioxide at high enough exposures can cause fibrotic lung changes, bronchostriction, and acute bronchitis among infants and school children. In sensitive plants, over several months of exposure it can cause collapsed lesions near the leaf margin and moderate injury. Lead at high enough concentrations impairs hemoglobin synthesis by increasing the lead levels in the blood. Sulfur dioxide and suspended particulate exposure causes higher frequencies of acute respiratory symptoms and diminished ventilatory functions in children. 3 2.4 Sanitary Landfill Considerations Included within the study area are an existing operational sani- tary landfill and a former Class II abandoned sanitary landfill. • The abandoned landfill has been covered; however, anaerobic de- composition of the organic matter present is occurring and caus- ing settling' as well as generating gaseous products which can be toxic and malodorous. The composition of gases exuded by sani- tary landfills is generally 50 to 55 percent methane and 40 to 45 percent carbon dioxide with traces of other gaseous elements such as ammonia and hydrogen sulfide. The mechanism of gas production in landfills and the factors affecting it have not been well understood. Major environmental factors affecting gas production appear to be moisture content, termperature, pH, alkalinity and nutrition. Generally, gas pro- duction will increase with temperature up to 55 degrees centi- grade beyond which decomposition rates decline sharply. Addi- tionally, less gas is produced in regions where soils exhibit lower moisture contents. Refuse placement and cover procedures and materials can affect • the movement of both gas and water at the surface of abandoned landfills. Landfills. covered by very tight caps which retard the release of noxious gases will experience lateral migration of these gases. In this instance, venting systems would be needed to allow the escape of these gases, particularly because of the explosion potential. and combustibility of methane. For this reason, escaping gases are often "burned off" or captured with recovery wells and harnessed as a source of energy. It is important to note that non-urban air naturally contains 1.0 to 1.5 ppm methane. Methane is virtually inert (non-reactive) and therefore does not contribute to the formation of photochemi- cal smog as other reactive hydrocarbons do. 2.5 Air Quality Management Plan (AQMP) The AQMP, adopted by the California Air Resources Board on May . 10, 1979 is the air quality management plan for the South Coast Air Basin. It was designed to meet and maintain federal and state ambient air standards by 1987. Required by the Clean Air Act (Amendments of 1977) , the AQMP was included in the State Implementation Plan and submitted to the Environmental Protection Agency in July 1979. The. plan includes measures to be implemen- ted by state and local agencies to achieve attainment by 1987. The plan includes 75 control measures which fall into five major categories: - Measures for cleaner industrial processes; - Measures for cleaner vehicles and fuels; - Measures to reduce congestion-related emissions; • - Incentives for ridesharing; - Measures for energy conservation. 4 • 3.0 AIR BUALITY IMPACT ANALYSIS Two types of air pollutant sources must be considered with re- spect to the proposed project: stationary sources and mobile sources. Stationary source considerations include emissions on- site from construction activities and natural gas combustion as well as emissions at the power plant associated with any electri- cal requirements for the project. Mobile source considerations include short-term construction activites and long-term traffic generation. 3. 1 Short-Term Impacts The primary impacts of the project are similar to those for any construction activity. Grading of the site will produce two types of contaminants: exhaust emissions from construction equipment and fugitive dust generated by earth movement. Atmos- pheric dust will be generated by the mechanical disturbance of the topsoil associated with construction activities. In addition to large dust particles that settle to the earth near the con- struction site (often creating a localized nuisance problem) considerable amounts of fine-grained fugitive dust particles will be emitted and dispersed over much greater distances. Dust emissions will occur during land clearing, ground excava- tion, cut and fill operations, and the construction of struc- tures, roads and parking lots on-site. These emissions will vary substantially from day to day depending on the level of activity, the specific construction operations, and the prevailing weather. " Significant amounts of fill may be necessary to develop the active recreation areas. Based upon field measurements by the EPA at medium activity construction sites with moderate silt content and semi-arid climates, 1.2 tons of fugitive dust per acre of construction per month of activity can be expected. The park expansion area includes 30 acres not all of which will be under construction at any one time. Exhaust emissions from construction activities include those associated with the transport of workers and machinery to the site as well as those produced on-site as the equipment is used. Without a precise construction plan, it is difficult to predict heavy-duty constuction equipment emissions because of the day-to- day variability in construction activity levels. The temporary emissions from the predominantly diesel-powered equipment may, however, be significant at times although sensitive receptors are not located downwind at distances small enough to cause concern. The motor vehicle emissions from consturction workers will be minor. 3.2 Long-Term Pollutant Emissions Long-term impacts are those associated with the permanent usage of the proposed park expansion. These include stationary and mobile source emissions. The air pollutant emissions can be projected for various years by multiplying the anticipated motor 5 vehicle, natural gas, and electrical usage rates by appropriate emission factors. The results obtained in this manner are shown in Table 1.

(See Appendix) As shown, stationary source emissions generated as a result of the proposed project represent approximately 14.3% of the total emission burden. In 19959 motor vehicle emissions will account for 85.7% of the project-related emissions, although exhaust control technology or legislation as well as. more stringent stationary source emission control measures may alter that total. It should be noted that the bulk of the air pollutant emissions (56.9% or . 12 ton of the .21 ton per day total ) will be carbon monoxide emitted from motor .vehicles. S Table 2 provides regional emission inventories for comparison with the project emissions. As shown, if the project were com- pleted immediately, the project-related emissions would represent far less than one percent (.03%) of the county-wide emissions in 1982. Although the project is expected to be built-out by 1985, the analysis addresses 1982 and 1995 for which traffic volume projections are available as well as 1982 and 1987 for which regional emission inventories are available for comparison. • 6 • TABLE 2 CENTRAL PARK EXPANSION AREA EMISSION INVENTORY COMPARISON Pollutant Project Emissions Orange County Emissions (Tons/Day) (Tons/Day) 1982 1995 1982 1987 CO .3279 . 1179 862.47 789.99 THC .0521 .0185 444.32 429.59 NOx .0676 .0437 142.45 156.76 Sox .0166 .0166 30.35 35.86 Particulates .0099 .0084 49. 11 49.83 Total .4741 .2051 1,528.70 1,462.03 Note: County-wide emission inventory courtesy of SCAQMD, Mr. Mike Nazemi, .Feb. 1980. 3.3 Long-Term Air Quality Projections The assessment of the project impact on localized ambient air quality requires that future ambient air quality levels be pro- jected. Carbon monoxide concentrations can be estimated adjacent •to Golden West, Slater and Talbert using the California Depart- ment of Transportation line source dispersion model Caline 3. Because of the relative inertness of carbon monoxide in the photochemical smog formation process, and limitations of know- ledge on dispersion characteristics of other air pollutant spe- cies, carbon monoxide is the most suitable• tracer pollutant for microscale modeling. Secondary pollutants are a large-scale phenomenon, and should be analyzed on a regional basis rather than a local one. The assumptions made in the Caline 3 modeling process are given in the Appendix. The results of the calculations appear in Table 3. As shown therein, the carbon monoxide concentrations adjacent to the roadways most heavily used by project traffic will be less than 14 ppm and well below the 40 ppm state standard and the 35 ppm federal standard for one hour. Over an 8-hour or 12-hour period, project-related traffic along these roadways will contribute approximately 0.05 ppm to the carbon monoxide concentration at 150 feet from the road. Conse- quently, if the federal 8-hour carbon monoxide standard of 9 ppm or the state 12-hour standard of 10 ppm . is equalled or exceeded 7 as a result of regional vehicular emissions, it will also be exceeded adjacent to .the project site. However, project-related traffic alone will not cause the 8 or 12-hour standards for carbon monoxide to be exceeded locally. Receptors located closer than 150 feet will experience identical carbon monoxide exposures with or without the proposed park expansion.

"worst case" or downwind corner. 3.4 Sanitary Landfill Considerations As mentioned earlier, the primary concerns related to the aban- doned landfill on-site focus on the combustibility of the methane gas produced by the decomposition occurring and the potential for impacts related to odors. The proposed expansion project in- cludes a 2,200 space vehicle parking facility with a turf or gravel surface to cover the abandoned landfill . The escaping methane gas will be studied in detail prior to a decision on whether to vent and burn off the methane or attempt its recovery and use. In order to reclaim as much methane as possible, it will be nec- essary to cap the abandoned landfill with an impermeable material which will prohibit lateral or vertical migration of decomposi- tion gases and limit the amount of oxygen entering the landfill . An uncapped or improperly capped landfill may experience reduced . or suspended anerobic decomposition. Further, the intrusion of oxygen could create potentially explosive conditions if concen- trations. of 5 to 15 percent methane are permitted to develop ("Control of Gas Flow From Sanitary Landfills", Houshang Esmaili , 1975) . Generally, gases are not vented from landfills by any means other than natural venting through the soil cover. Structures built on or near a landfill may therefore require protection by a forced 8 I _ air withdrawl or other system. The best control of odors is achieved through the rapid and continuous coverage of solid wastes and the sealing of surface cracks in completed landfill areas to prevent emissions , of large concentrations of odorous gases. Despite these precautions, the abandoned landfill could produce objectionable odors if disturbed during the construction process. 3.5 Planning Mode Alternatives Four land use alternatives have been studied by Huntington Beach City Staff for a 25 acre planning mode or study area adjacent to the Huntington Beach Central Park. The development alternatives included: 1. Garden offices with an adjoining restaurant 2. Residential development at various densities 3. Recreational vehicle park 4. Commercial nursery/tree farm The "Planning Mode Study Area Special Report" recently prepared by City staff analyzed each land use alternative and concluded that each alternative would adversely impact air quality within the South Coast Air Basin. An air pollutant emission inventory was included for each alternative and has been reproduced below: TABLE 4 PLANNING MODE AIR POLLUTANT EMISSION INVENTORY Land Use Alternative Air Pollutant Emissions (Tons/Day) Garden Offices/Restaurant 0.67 Estate Residential 0. 16 Low Density Residential 0.24 Medium Density Residential 0.40 Recreational Vehicle Park 0.06 Nursery/Tree Farm 0.07 Source: Huntington Beach Planning Division, 1982. As shown in Table 4. the more intense land use alternatives such as the garden offices or medium density residential development generate larger quantities of air pollutants. The recreational vehicle park or nursery alternatives generate less than 150 pounds of air pollutants daily, most of which will be dispersed over a large area by vehicles approaching or leaving the site. 3.6 Cumulative and Growth Inducing Impacts Cumulative impacts of growth proposed for the surrounding area have been taken into account in the ultimate 1995 analysis and 9 I • the ultimate 1995 plus project analysis in Section 3.3. The proposed project is the result of previous growth inducements in the area. The project is not being proposed in a totally unur- • banized area where infrastructure is absent or arterial highways do not exist. Conversely, the site is served by arterial high- ways and bounded by residential and other developments. The AQMP assumes a level of growth consistent with SCAB 7e. The implementation of the AQMP may require that some of the growth provided for in County and City General Plans be modified, elim- inated or delayed if that growth will prevent or interfere with the attainment and maintenance of ambient air quality goals. Since the growth accommodated by the proposed project will cumu- latively impact the ambient air quality of the region, but will most likely not exceed SCAB 76 forecasts or cause local air pollutant concentrations to exceed the relevant standards, its consistency with the intent of the provisions of the AQMP is clear. • • • . 10 • 4.0 MITIGATION MEASURES The most effective air pollution mitigation measure for consider- ation during project design is a substantial reduction in VMT. This can be achieved by providing recreational opportunities near the residents they are designed to serve. The project accom- plishes this goal through its design and location. Measures selected for incorporation• in the project include: 1) Adequate watering techniques will be employed to partially mitigate the impact of construction-generated dust particu- lates. 2) SCAQMD Rule 403 will be adhered to. 3) The installation of thermal insulation in walls and ceilings which meets or exceeds standards establiched by the State of California or the Department of Building and Safety. The following mitigations are offered as suggested measures which can be incorporated as conditions of approval , should the City of Huntington Beach so determine, to further reduce the air quality impacts associated with the project. 1) The preferential use of diesel-powered construction equip- ment rather than gasoline-powered equipment, to affect ex- haust emission reductions and evaporative and crankcase HC emission reductions. 2) The covering of all trucks filled with soil that exceed 20 mph or venture off-site. 3) Speed control of 20 mph on unpaved surfaces. 4) The balance of cut and fill quantities on-site to eliminate the need for imported or exported soil. li • • APPEND I X • • Table CONPINISONS Of III OU►IiTT STINOIROS All ENEROENCT CRITERIA Air Air olit StonderdsA [a ralacy Clitoris Pollutant Notional SCAOmDc and California Episode National Episode and State I Emergency Sigellicanl Action California Primary Secondary Nealth Stage 2 Stags 3 Ilart Veining Action Narm To Required Advisory Warning Emergency level level level Nealth level 0.12 ppm 0.12 ppm ozone 5.15 ppa.

Daily traffic volumes were converted to peak hour and average hourly volumes for the 8-hour runs by. assuming that 10 percent of the daily volume occurs during the peak hour and 60 percent of the daily volume occurs during the peak . 8 hours. • Average Speeds -- of. 35 m.p.h. were assumed for the streets. Meteorological Conditions -- included 2 m.p.h. winds, stability clases of C, D and E, and wind directions to and from the northeast depending upon the time of day for typical October conditions, when CO concentrations are highest. • Highway Widths -- were based on the City of Huntington Beach Circulation Plan of Arterial Streets and Highways. The widths included 3 meters per side as specified for the Caline 3 model input. • Emission Factors -- were taken from EMFAC 6C as provided in a computer run dated July 29, 1981 made by the Orange County EMA and shown below. CALIFORNIA CORRECTED MOTOR VEHICLE EMISSION FACTORS • Pollutant 1982 (gm/mi ) 1995 (gm/mi ) CO 14.90 5.32 • THC 2.33 0.80 NOx 2.49 1.40 SOx 0.20 0.20 • Parts. 0.37 0.30 Note: Carbon monoxide emission factors of 19.34 and 5.32 (gm/mi ) respectively, were assumed for 1980 and 1995. • Background Concentrations -- for carbon monoxide were derived from ambient air quality data for 1980 taken as the Orange County summary figures by the CARB. The second highest hourly concentrations were used (ie. 18.4 ppm for the 8-hour average, 25.0 ppm for the 1-hour average, and 16.8 ppm for the 12-hour average) . These levels were proportionally reduced to reflect • two trends anticipated by the year 1995. First, the reduction in i emission rates between 1980 and 1995 resulting from emission control technology was used to reduce the 1980 ambient • concentrations of carbon monoxide. Next, the increase in the number of in-use vehicles was accounted for by proportionally increasing the 6.25 million vehicles in the South Coast Air Basin during 1976 to 12.0 million vehicles by 1995. This growth amounts to a 3.5 percent increase annually per the CARD document entitled "Procedure and Basis for Estimating On- Road Motor Vehicle Emissions" dated January 1980. The resulting 1995 background or ambient concentrations of carbon monoxide were found to be 13.20 ppm, 9.72 ppm and 8.87 ppm respectively for the 1-hour, 8-hour and 12-hour averaging periods. • I • • CALINE3: CALIFORNIA LINE SOURCE DISPERSION MODEL • SEPTEMBER, 1979 VERSION JOB: HB PARK FILE: HBPARKI RUN: GOTHARD (NS) a TALBERT (EW) (PK-HR) W/O PROJECT • I.

Huntington Central Park Expansion Project, City of Huntington Beach . References : 1 . "City of Huntington Beach Central Park Traffic Study ," prepared by Kunzman Associates. 2 .

Gentlemen : Measurements have been obtained and an analysis has been performed to determine the existing and projected noise levels within the study area of the proposed Huntington Central Park expansion project. In addition to traffic, the impact of other sources of noise more directly associated with the project itself have been assessed and mitigation methods have been identified where considered necessary . The following provides the results of the assessment: NOISE EVALUATION CRITERIA AND STANDARDS The Noise Element of the General Plan for the City of Huntington Beach indicates that the community noise equivalent level ( CNEL) shall not exceed 60 dB within the exterior living spaces of residential locations and shall not exceed 45 dB within the interior living spaces. ( Refer to Appendix I for an explanation of the A-weighted measure of noise level and the CNEL measure of noise exposure. ) An exterior CNEL of 70 dB is also specified for recreational areas such as the park, and 80 dB is specified for general commercial uses. ENVISTA, INC. Project File No. 1108-82 April 5 , 1982 Page Two In addition to the above , the noise ordinance for the city of Huntington Beach specifies noise levels which shall not be exceeded by activities within the park when experienced at nearby land uses: Exterior Noise Standards Land Use Noise Level Time Period Residential 55 dB( A) 7 am - 10 pm 50 dB( A) 10 pm - 7 am Public Institution 55 dB( A) Anytime Commercial Property 60 dB( A) Anytime In the event the offensive noise consists entirely of impact noise , simple tone noise , speech , music , or - any combination of these sources , each of the above noise levels is reduced by 5 dB( A) . These standards are further altered to account for and permit higher noise levels for various durations each hour . The maximum noise level which may be generated at a residential location is 75 dB( A) during the daytime and 70 dB( A) during the nighttime . EXISTING AND PROJECTED NOISE LEVELS Three sources of noise have been examined for this study: ( 1 ) traffic on the arterials within the study area , (2) activity at the proposed ball park complex , and ( 3) activity at the proposed gun range expansion . Each of these has been examined in . detail below: Traffic on the Arterial System Noise measurements were obtained at five positions in the study area . These positions are identified in Figure 1 . The data obtained is provided in Appendix II and is summarized in the table below: J. J. VAN HOUTEN & ASSOCIATES, Inc. • ENVISTA, INC. Project File No. 1108-82 April 5 , 1982 Page Three • Sound Levels Position L50 L10 Leo • Corner of Rio Vista & Golden West 64 dB( A) 71 dB( A) 66 dB( A) East End of Jardin es Dr. 43 47 45 • East End of Central Park Dr. 49 56 54 Additional Parking Lot of the Library 57 60 59 Corner of Ellis & Golden West 59 66 63 The sound levels indicated above ( L501 L10, and Leq) provide the noise level exceeded during 50% and 10% of the measurement period and the energy equivalent sound level ( Leq) for the measurement period . In addition to the noise measurements , an analysis has been . performed using the data of the referenced traffic study to determine the CNEL generated on the arterials within the study area. The results of this analysis , including the distance from the arterials to the CNEL contour lines (60, 65 , and 70 dB) are provided in Appendix III. Ball Park Activity The noise generated by spectators at a ball game has been measured • ( reference 3) . This data indicates that the peak noise level generated by about 450 people when measured at 400 feet is 88 dB( A) . It is noted that this maximum level will only occur when the spectators are cheering or yelling in unison. On March 31 , 1982 a measurement was obtained at Covina High School with thirty students yelling in unison. The results essentially agree with the data • provided in reference 3 . In addition to the spectators , another source of noise will be the loudspeaker systems used at each ball park. It is estimated that in order to be effective , the systems will need to generate a sound level of at least 75 dB( A) at the spectators ' locations. • J. J. VAN HOUTEN & ASSOCIATES, Inc. • ENVISTA, INC. Project File No. 1108-82 April 5 , 1982 Page Four In order to estimate the maximum amount of noise that will be generated at the nearest noise-sensitive location to a ball park, it is assumed that the spectator noise of only one game is experienced at each noise-sensitive location in proximity to the proposed ball park complex . Hence , the calculations have been performed for the nearest ball park to each location being considered. Using this case , it is determined that the peak spectator noise level at the nearest residence and at the library will be about 74 to 75 dB( A) . At the proposed YMCA, the peak noise level will be about 77 to 80 dB( A) ; and , at the planning mode alternative site, the peak noise level will be less than 65 dB( A) . These values take into account the orientation of the bleachers with respect to the noise sensitive locations. That is , up to 20 dB( A) of noise reduction is assumed for bleachers which are facing away from these areas ( refer to Figure 2 for orientations) . If a loudspeaker system is used at the facility nearest to the noise-sensitive location being studied , it is estimated that the sound level at the nearest homes and at the library will be about 54 dB( A) . At the .YMCA, it is estimated that the sound level will be about 69 dB( A) and about 59 dB( A) at the nearest position on the alternative planning mode site to the ball fields. Gun Range Noise Measurements of activity at the existing gun range were obtained at a position in the southerly parking lot of the library ( about 600 feet north of the range) . At this distance , individual weapon firing generates a peak noise level of 54 to 58 dB( A) . Using this data, the peak noise level generated at the nearby noise sensitive areas by activity at the gun range can be calculated . Thus, it is estimated that the peak noise level at the library will be about 49 to 53 dB( A) and about 62 to 66 dB( A) at the nearest position on the planning mode alternative site to the gun range . ASSESSMENT OF IMPACT The impact of noise in relation to the city of Huntington Beach noise ordinance and Noise Element has been assessed for each of the three sources of noise within the study area: ( 1 ) traffic on the arterials, ( 2) activity at the six proposed ball park facilities , J. J. VAN HOUTEN & ASSOCIATES, Inc. • ENVISTA, INC. Project File No. 1108-82 April 5, 1982 Page Five • and ( 3) activity at the expanded gun range . These are discussed separately below. The impact for each of these sources is assessed • according to the criteria listed in Table 1 . Arterial Traffic The following is noted from the noise measurements and an analysis of the traffic data developed by Kunzman Associates ( reference 1 ) : 1 • A significant impact currently exists at residential locations directly adjacent to Warner, Slater, Golden West, Beach , and a portion of Edwards. 2 . A significant impact is projected for residential locations directly adjacent to all arterials within the study area except • for some reaches of Talbert , Ellis , and Edwards. This will occur with or without the project . In addition, a significant impact is projected for the portions of the park that are adjacent to Golden West. Again , this will occur with or without the project. 3 . The exterior CNEL at the location of the planning mode alternative is currently greater than 65 dB. It is expected to be greater than 70 dB by 1995 with or without the project . Therefore , a significant impact exists and will need to be mitigated if residential construction is planned for this area. • Ball Park Activity Since the ball park facilities are to be lighted , the assessment of noise impact should be evaluated relative to the Huntington Beach noise ordinance nighttime standards. That is , the maximum noise level which should be generated by ball park activity when measured at an adjacent residence is 70 dB( A) . In addition , the maximum noise level when measured at a public institution ( such as the library or YMCA) should not exceed 75 dB( A) . If the ball park noise is clearly discernible as speech , then a 5 dB(A) correction would. be applied to these values . However , for the distances involved and . number of people generating the noise , the five decibel reduction • in standard is not considered appropriate. The analysis performed earlier indicates a peak spectator noise level of 74 to 75 dB( A) at the nearest residence and at the library, 77 to 80 dB( A) at the proposed YMCA, and less than 65 dB( A) at the northern portions of the planning mode alternative. • site. Thus, for nighttime activity a significant impact will exist J. J. VAN HOUTEN & ASSOCIATES, Inc. • ENVISTA, INC. Project File No. 1108-82 April 5 , 19.82 Page Six at all of these locations as a result of spectator noise at the proposed ball park facilities. It is noted , however, that an insignificant impact will exist at the northern portions of the planning mode alternative even if it is developed as residential . • The peak noise level generated by the loudspeaker systems at the proposed ball park facilities is not expected to create a significant impact at any of the noise sensitive locations near the ball park. However, the loudspeaker systems will be clearly discernible above the ambient noise level and, therefore, represent a potential source of annoyance . Traffic noise on Golden West may provide a masking effect for the ball park noise when experienced at the library or the site of the alternative planning mode . However, this effect will be lessened at night as traffic volumes decrease. Gun Range Activity Based upon the Huntington Beach noise ordinance standards and the estimated peak noise levels generated by activity at the gun range , it is determined that an insignificant impact will exist at noise sensitive locations in proximity to. the gun range . However, a significant impact may exist at some residential locations in the northern portion of the planning mode alternative site if activity at the gun range occurs during the nighttime and early morning hours ( 10: 00 p.m. to 7 : 00 a.m. ) In any event, the weapon firing may be annoying to residents living in proximity to the gun range since the sound will be discernible above the ambient noise level . CONSTRUCTION NOISE Annoyance due to construction noise during the development of the park will be minimal . Equipment associated with grading and excavation produces potential annoyance . However , the duration of • this activity is only for a few weeks . Construction noise may cause considerable annoyance if it occurs after 7 : 00 p.m. on weekdays and during the day on Sundays. Figure 3 identifies the level of construction activity noise , some of which will be generated by truck movements to and from the site and within the park itself. MITIGATION OF EXCESSIVE NOISE I In order to provide a project which complies with the city of Huntington Beach noise ordinance and Noise Element , the following mitigation measures should be considered : • J. J. VAN HOUTEN & ASSOCIATES, Inc. • ENVISTA, INC. Project File No. 1108-82 April 5 , 1982 Page Seven • 1 • Activity at the ball park facilities should be limited to the hours of 7 : 00 a .m. to 10 :00 p.m. • 2 . Crowd sizes at the two ball park facilities nearest to the proposed YMCA should be limited to no more than 25 to 40 people. 3 . Bleachers and loudspeakers at the ball park facilities should be oriented away from nearby noise sensitive areas whenever • possible ( refer to Figure 2) . 4 . (abou eakers4 ��hould be placed at the center of a large baffle 5 . The loudspeakers should be placed near the bleachers and should • be controlled so that the peak sound level (when measured at the spectator locations) is no greater than 75 dB( A) . 6 . An alternative to items 1 through 5 , above , would be the construction of a continuous berm/wall combination around the ball park area. A combined height of about 7 feet would be • needed on the north, west, and east sides and a height of about 11 feet would be needed on the south side . The barriers could be constructed entirely by use of an earth fill or any combination of earth fill and block wall as needed to achieve the heights of 7 or 11 feet. • 7 . Activity at the gun range should be limited to the hours of 7 : 00 a .m. to 10 : 00 p.m . 8 . The type of weapons that will be used at the expanded gun range should be limited to the largest caliber currently being fired . • 9 . If a residential community is developed at the planning mode alternative site , a noise barrier with a minimum height of 6 to 7 feet will be needed adjacent to Golden West and Ellis in order to reduce traffic noise to acceptable levels . CONCLUSION • Measurements have been obtained and an analysis has been performed to determine the existing and projected noise levels within the study area for the proposed expansion of the Huntington Beach Central Park. It is found that a significant impact due to traffic • J. J. VAN HOUTEN & ASSOCIATES, Inc. • ENVISTA, INC. Project File No. 1108-82 April ,5 , 1982 Page Eight noise currently exists in many portions of the study area . This impact will increase in the future as traffic volumes in the area increase, with or without the project . • The primary source of noise associated with the proposed expansion of the park will be activity at the ball park facilities. A significant impact due to spectator noise is projected for all noise sensitive locations in proximity to the ball park facilities. Methods of reducing the impact of spectator noise have been provided. It should be noted , however, that the ball park noise ( spectators and loudspeakers) will be discernible at all noise sensitive areas in proximity to the proposed facilities , especially during the evening hours . This may be annoying to ' people residing near the sports facilities.

Recommended Locations of Bleachers and Loudspeakers In Order to Hinimize the Impact of Voice at Nearby Noise Sensitive Locations N APPENDIX I NOISE EVALUATION CRITERIA AND STANDARDS A description of the character of a particular noise .requires the following: 1. amplitude and amplitude variation of the acoustics wave, 2 . frequency (pitch) content of the wave motion, and 3. duration of the noise. The scale of measurement which is most useful in community noise measurement is the A-weighted sound pressure level , commonly called the A-level or dB(A) . It is measured in decibels to provide a scale with the range and characteristics most consistent with that of people ' s hearing ability. A-Weighted Sound Level To establish the A-weighted sound level, the acoustics signal is detected by the microphone and then filtered (heavily weighting those portions of the noise which are most annoying to individuals) . _ This weighting of sound energy corresponds approximately to the relative annoyance to human senses of noise experienced at various frequencies . The A-weighted sound pressure levels of a few typical sources of noise experienced by people within the general vicinity of the subject project are indicated in Figure I-1. The A-weighted sound level of traffic noise and other long-term noise producing activities within and around the community varies considerably with time. Measurements of this varying level are accomplished by recording the values of the noise for a specified period of time . An analysis of these recordings yields the A-level values for noise which are useful in assessing the potential annoyance of the disturbance. For purposes of this study, the following values have been used: L90 - The near minimum A-level . 90% of the time, the A-level is greater than this value. Lso - The central tendency of A-level . This value is exceeded 50% of the time during the measurement period. Lio - The near maximum A-level . This value is a measure of the long- term annoyance of the noise . 10% of the time, the A-level is greater than this value. Leq - The energy equivalent level is representative of the long-term annoyance potential of the noise . Readings of these measures are recorded to provide representative samples of the noise during the time period being examined (i.e . , peak traffic period, morning , afternoon, night, etc. ) . • Appendix I, Continued Page Two • Community Noise Equivalent Level (CNEL) It is recognized that a given level of noise may be more or less tolerable depending on the duration of exposure experienced by an • individual . There are numerous measures of noise exposure which consider not only the A-level variation of noise but also the duration of the disturbance. The State Department of Aeronautics and the California Commission on Housing and Community Development have adopted the community noise equivalent level (CNEL) . This measure considers the weighted average noise levels for the evening hours • (7 : 00 p.m. to 10 : 00 p .m. ) and increases the levels by 5 dB, and increases the late evening and morning hours noise levels (10 :00 p.m. to 7 :00 a.m. ) by 10 dB. The daytime noise levels are combined with these weighted levels and are averaged to obtain a CNEL value. Figure I-2 indicates the outdoor CNEL at typical locations . • Acceptable Exterior Noise Exposures - CNEL Figure I-3 indicates the CNEL considered acceptable for various land use categories . In general, exterior noise exposures at resi- dential locations "should not exceed a CNEL of 65 dB. • The U. S. Environmental Protection Agency has promulgated a recommended policy for exterior noise exposures which,. in effect, suggest that a CNEL which is no greater than 55 dB should be permitted within exterior living spaces . However, they emphasize that this level of exposure may not be economically feasible or, in many cases , may not be a practical level to achieve. • Acceptable Interior Noise Exposures - CNEL California' s Noise Insulation Standards were officially adopted by the California Commission on Housing and Community Development in 1974. The regulations became effective on August 22 , 1974. The ruling states that "interior community noise equivalent level (CNEL) attributable to exterior sources shall not exceed an annual CNEL of 45 dB in any habitable room" . Additionally, the Commission specified that residential buildings or structures to be located within exterior community noise equivalent level contours of 60 dB or greater of an existing or adopted freeway, expressway, parkway , major street, thoroughfare, railroad, rapid transit line , or industrial noise source shall require an acoustical analysis showing that the building has been designed to limit intruding noise to the level prescribed (interior CNEL of 45 dB) . • • Wife Sound ted NOISE SOURCE A sh LeveldB((A)A) NOISE SOURCE -12 - RIVETING THRESHOLD OF PAIN SMALL AIRCRAFT OVERHEAD — MACHINE 30 TO 40 FEET TRAIN PASSING 50 FEET — — AUTOMOBILE HORN 59 FEET AWAY NOISY STENOGRAPHIC ROOM -1170- AVERAGE CONVERSATION, 3 FEET NOISY OFFICE NOISY RESIDENCE, INTERIOR QUIET OFFICE — — VOICE - VERY SOFT WHISPER, 3 FEET — - -2a— OUTDOOR IN RURAL AREA THRESHOLD OF AUDIBILITY =U— Figure I-1.

Gentlemen: The enclosed noise contour maps have been prepared as part of the noise assessment study for the proposed expansion of Huntington Cen- tral Park (reference 1) . Figure 1 provides the community noise equivalent level (CNEL) contours for the future (1995) traffic volumes on the major arterials within the study area for the "with project" case. These traffic volumes were obtained from the traffic study prepared by Kunzman Associates (reference 2) .

Barnes Associate Planner Department of Development Services City of Huntington Beach - Post Office Box 190 Huntington Beach, CA 92648 Dear Mr. Barnes: The California Department of Health Services, Hazardous Material Management Branch, is conducting a statewide survey to locate inactive or abandoned hazardous waste disposal sites that.were used between 1945 and 1972. The survey is now being conducted in Orange County and consists of a search of public agency records and use of a questionnaire through which operating industries provide information regarding their past waste disposal practices. Information received by the Department of Health Services indicates that your agency is in the process of preparing an Environmental Impact Report. for the development of a piece of property formerly known as the Bruce Bro- thers Pit. The site is located between Goldenwest and Gothard on Talbert in the City of Huntington Beach. In light of the inpending development of • the Bruce Brothers Site, we would like to provide the City with a .summ�ary of historical hazardous waste disposal data gathered thus far on the subject site. As part of this on-going study the Department has found that the Bruce Bros. Pit was a sand excavation operation prior to 1927. From 1927 to 1949 the • pit was used as a disposal site for industrial wastes from oil fields. In 1948 a restraining order was issued to the site operators by the. California Dept. of Public Health prohibiting any furth'ei disposal of "brines, waste oil sludges and other offensive substances".- From 1949 to 1957 the pit was used as a disposal site for "rotary muds and-1waste muds from sumps". In 1957 Industrial Waste Disposal Permit #80 was issued to the operators from the Water Pollution Control Division of the -County of-Orange for the disposal of inert materials. From 1957 to 1973 the Water Pollution Divi'sign noted permit violations for disposal of "liquid refinery wastes", "oil and brines", and "sump bottoms" to the site. In 1973 the City of Huntington Beach purchased the property and closed the pit. • Based on the historical waste disposal data compiled so far by the Department, the site is currently considered to be a potential hazardous waste disposal • RECEIVED UTAR 91982 CNVISTA.
