Community Services City of Huntington Beach 2000 Main Street, HB, CA 92648 REGARDING: Appeal of the Planning Commission's Condition "7(y) " as to the approved C=Itional Use I-erutt No. 00-607'- Variance No. 00-24 (Huntington Central Park Sports Complex) Tentative Date for Public Hearing: To be determined Copy of Appeal Letter attached. LEGAL NOTICE AND A.P.MAILING LIST MUST BE RECEIVED IN THE CITY CLERK'S OFFICE 15 DAYS PRIOR TO THE PUBLIC HEARING DATE Connie Brockway City Clerk x5227 Planning Commission Recommendation ATTACHMENT NO. 1 FINDINGS AND CONDITIONS OF APPROVAL CONDITIONAL USE PERMIT NO. 00-60NARIANCE NO. 00-24 FINDINGS FOR CEOA: The Planning Commission finds that this project was analyzed under Final EIR No. 99-1 certified by the City Council in August 1999. All applicable mitigation measures identified in Final EIR No. 99-1 are included in the conditions of approval. FINDINGS FOR APPROVAL - CONDITIONAL USE PERMIT NO. 00-60: 1. Conditional Use Permit No. 00-60 to: a) construct a sports complex on a 45-acre site; b) allow development on a site with greater than a three foot grade differential between the low point and high point; c) allow walls and fences up to a maximum height of 30 feet in lieu of 3.5 feet high within the front, interior side, and rear yards; specifically 1)an eight foot high wall along Goldenwest Street at the main driveway;2) a four foot high tubular fence along Gothard Street; 3) an eight foot high wall along the south boundary next to the mobile home park;and 4) a 30 foot backstop along the south lot line will not be detrimental to the general welfare of persons working or residing in the vicinity or detrimental to the value of the property and improvements in the neighborhood. The sports complex will improve a vacant site with an attractive facility,which incorporates quality landscaping, as well as attractive public plazas,project monumentation, and concession/restroom buildings. It will provide much needed sports facilities for use by participants in various city sports programs. All the proposed walls within the required setback areas serve to protect the users of the sports complex as well as the surrounding uses. Adequate parking for the use is provided entirely on site. 2. The conditional use permit will be compatible with surrounding uses because the sports complex is an extension of the character and purpose of Central Park to provide park and recreation amenities to citizens as well as visitors. Mitigation measures have been.incorporated into the design to reduce potential impacts.to a level that is less than significant, including restrictions on use and lighting. A significant setback and privacy wall are provided for the abutting mobile home park. Substantial landscaped setbacks along all street frontages will provide an attractive and pleasing buffer. The site will be graded to allow proper drainage while achieving compatibility with the surrounding area to the greatest extent feasible. 3. The proposed project will comply with the provisions of the base district and other applicable provisions in Titles 20-25 of the Huntington Beach Zoning and Subdivision Ordinance, as well as any specific condition required for the proposed use in the district in which it would be located, except for any variances approved concurrently. The project meets or exceeds all minimum development (OOSR66)- 10/24/00 _ Attachment No. 1.1 requirements including setbacks for the buildings, landscaping,parking, and site coverage among others. \ 4. The granting of the conditional use permit will not adversely affect the General Plan. It is consistent with the Land Use�Element designation of OS-P (Open Space-Park)on the subject property which permits parks and recreation facilities.. In addition, it is consistent with the following goals and policies of the General Plan: a. LU 4-Achieve and maintain high quality architecture, landscape, and public open spaces in the City. b. LU 14.1.1 -Accommodate the development of public parks . . . in areas designated for Open Space on the Land Use Plan Map. c. LU 14.1.3 -Require that structures located in the City's parks and other open spaces are designed to maintain the environmental character in which they are located'. d. RCS 1 -Enrich the quality of life for all citizens of Huntington Beach by providing constructive and creative leisure opportunities. e. RCS 1.1.4 -Encourage and facilitate the development of a wide variety of revenue generating recreational activities such as corporate,picnic facilities,wedding facilities, infant, child, or senior day care, fishing facilities, golf courses,ranges,battingcages,roller hockey, sports fields, etc. f. RCS 3 -Develop park sites to provide diverse recreational and sports facilities that meet the residents' and visitors' active and passive recreational needs. g. RCS 3.1.3 -Develop public parks and recreation facilities that link trails and existing recreational facilities. FINDINGS FOR APPROVAL-VARIANCE NO. 00-24: 1. The granting of Variance No. 00-24 to allow a 20 foot landscaped setback in lieu of 25 feet for an 85 foot portion along Gothard to allow the installation of built-in bleachers will not constitute a grant of special privilege inconsistent with limitations upon other properties in the vicinity and under an identical zone classification. Other properties in the city have been granted variances for minor landscaped setback encroachments similar to that proposed for this project. ,The project overall.. exceeds all other landscaping requirements including percentage of landscaping provided at 47 percent where only eight percent is required 2. Because of special circumstances applicable to the subject property,including size and shape,the strict application of the zoning ordinance is found to deprive the subject property of privileges enjoyed by other properties in the vicinity and under identical zone classification. The site has an odd shaped north boundary which restricts the layout of the sports fields. Approval of the variance will allow bleachers to be provided along the Gothard Street frontage at a landscaped setback of 20 feet in lieu of 25 feet. (OOSR66)- 10/24/00 Attachment No. 1.2 3. The granting of a variance is necessary to preserve the enjoyment of one or more substantial property rights. Approvarof the variance will allow for an efficient use of the site by providing the maximum number of sports fields with all the requisite amenities such as bleachers. 4. The granting of the variance will not be materially detrimental to the public welfare or injurious to property in the same zone classification. The variance represents a minor reduction in the required 25 foot landscaped setback along Gothard Street down to 20 feet for only an 85 foot portion of the entire 630 foot frontage along Gothard. Overall landscaping percentage(47 percent provided where minimum 8 percent is required) as well as tree count for the project significantly exceeds the minimum code requirements. 5. The granting of the variance will not adversely affect the General Plan. It is consistent with the Land Use Element designation of OS-P (Open Space-Park) on the subject property which permits the proposed sports complex. CONDITIONS OF APPROVAL—CONDITIONAL USE PERMIT NO. 00-60 AND VARIANCE NO.00-24: 1.

Biological Resources 6: Concurrent with the operation of the Sports Complex,the City shall implement or cause to be implemented a brown-headed cowbird trapping program. The brown- headed cowbird trapping program will be submitted to the Service for review and comment at least three months prior to the beginning of grading. Traps used to remove cowbirds will be modified Australian crow traps. These traps allow live capture of birds so that non-target birds can be released unharmed. The traps will be baited with live juvenile or female brown-headed cowbirds which will be captured prior to the trapping period with baited traps or mist nets. The juvenile or female cowbirds attract the attention of adult birds and lure them into traps: Once inside the trap, it is difficult for the birds to escape and they can be easily removed. Approximately four bait birds are kept in a separate cage within the trap and are not removed until the trapping season is over. The traps will be placed and maintained so as to provide trapped and bait birds ample shade, food, and water while they are in traps. All cowbirds(male, female, and juvenile) that are caught in the traps will be disposed of humanely. Trapping will take place during the nesting period of riparian bird species found in Central Park that are known to be parasitized by brown-headed cowbirds. Traps will be checked daily during the trapping period to remove both trapped cowbirds and non-target species, which will be released. Bait birds lost to predation or escape will be replaced during the daily checks. ACHVENT N0.S.V___A (OOSR66)- 10/24/00 Attachment No. 1.13 An annual letter report documenting the results of the trapping program will be submitted to the US Fish and Wildlife Service. Results of the trapping program will be recorded including the date and time of trap checking, observer(s),weather, age of trapped birds(both target and non-target species), treatment of the birds (whether released, disposed of, or retained as bait birds), and other data pertaining to any unusual event, such as predation or loss of bait birds.

A', iACHMENTNOI,"V* (OOSR66)- 10/24/00 Attachment No. 1.18 Attachment"A" (#15,items a-e) There are an insufficient number of sports fields to serve the growing number ' of youth and adults participating in sports programs within the city. The city has analyzed the available areas in Huntington Beach to construct a sports complex to meet current demands. The only area that has enough space to construct such a complex is a 45 acre undeveloped section of Huntington Central Park (refer to CUP application for location and description of property) The project site will be mitigated based upon the certified environmental impact report on the area that was completed in 1999. Site developments will include eight(8) lighted softball fields overlaid with eight (8) soccer fields, on site parking for 800 vehicles, two restroom/concession buildings, relocation of a maintenance building and two (2) tot lots. It is anticipated that the majority of use on.the site will be for the city's adult softball program. League games are conducted six nights per week from 6:30 to 10:30 p.m.with a total of three games per field each night. Softball tournament groups will also utilize the fields on Saturdays from 8:00 a.m. to 8:00 p.m. Youth sports groups will conduct regional soccer tournaments on the site a total of six weekends per year. Spectators and sports participants will utilize the concession buildings and tot lots. Staffing requirements will be limited to city field maintenance personnel (one full and one part-time) and concession operation staff. Continuation of Huntington Central Park, the City's Central Library and a Standard Oil yard are located to the north of the project. The continuation of Central Park and the City's Equestrian Center are located at the west, a city owned mobile home park is located to the south (Ocean View Estates) and Sully Miller Lake and the non-operational Orange County Transfer Station are located to the east. Based upon the State of California Hazardous Waste and Substance.Site List (Section 65962.5 of the Government Code),the project location is not located within a Hazardous Waste and Substance site.

Staffs Recommendation: Approve Conditional Use Permit No. 00-60 with minor modifications based upon the following: The project will provide sports fields to serve the growing needs of participants in sports programs within the city. The project will comply with all applicable mitigation measures identified in Final EIR No. 99-1. The project will improve a vacant site with an attractive facility which incorporates quality landscaping as well as attractive public plazas,project monumentation and concession/restroom buildings. All proposed walls are designed to protect the users of the sports complex as well as the surrounding uses. The site will be graded to achieve compatibility with the surrounding area to the greatest extent feasible. PC Minutes— 10/24/00 11 (00pcm 1024) ATTACHMENT NO. . i Approve Variance No. 00-24 based upon the follawin : The reduction in landscaped setback from the required 25 feet to 20 feet applies only to an 85-foot segment along Gothard Street to allow the construction of built- in bleachers. Overall landscaping for the project well exceeds the minimum code requirement in all other aspects. THE PUBLIC HEARING WAS OPENED: John Scandura, Huntington Beach Environmental Board(no address provided), spoke in favor of the item and explained the Environmental Board's endorsement of a landfill gas collection system underneath the main parking area, and the landscaping plans. THERE WERE NO OTHER PERSONS PRESENT TO SPEAK FOR OR AGAINST THE REQUEST AND THE PUBLIC HEARING WAS CLOSED. Discussion ensued regarding the following items: traffic conditions on Goldenwest, parking, security lighting,hours of operation, landscaping, irrigation,bench design and signage. The Commission suggested inclusion of a pedestrian-activated crosswalk on Goldenwest adjacent to Goldenwest Plaza. The Commission also requested that staff make sure that the proposed park benches meet with the City's Urban Design Guidelines. Staff informed the Commission that parking meters will not be included in the project. The Commission inquired about the status of the Agra Geotechnical Report. Staff responded that the report was not yet available. Vinyl chloride concentration, dynamic soil compaction and urban runoff drainage related to the Sully Miller basin were also discussed and staff provided information on these items to the Commission.

Beardsley, Director of Public Works DATE: November 15, 2000 SUBJECT: EVALUATION OF THE PLANNING COMMISSION'S CONDITION FOR A PEDESTRIAN SIGNAL ON GOLDEN WEST STREET FOR THE HUNTINGTON CENTRAL PARK SPORTS COMPLEX Statement of Issue: Should a pedestrian signal be installed on Golden West Street between Ellis Avenue and Talbert Avenue as part of the Huntington Central Park Sports Complex or should other measures be considered to discourage potential random pedestrian crossings in this area? Funding Source: While not included in the current estimate for development of the Huntington Central Park Sports Complex, the $120,000 cost of a traffic signal could be included within the budget already established for this project. Recommended Action: MOTION to recommend that the City Council delete the Planning Commission's Condition "7y" from the approved Conditional Use Permit No. 00-60/Variance No. 00-24 for the Huntington Central Park Sports Complex which indicates: "The City shall install a signalized pedestrian crosswalk on Golden West Street near Golden West Plaza.The signal shall_ remain green for north and southbound traffic on Golden West Street until crossing is required by pedestrians." And, to recommend the addition of continuous 4' high weatherized fencing along the west side of the meandering sidewalk within the sports complex adjacent to Golden West Street. Alternative Action(s): Do not approve this request and support the Planning Commission's action requiring a signalized pedestrian crosswalk on Golden West Street. i PWC Central Park Goldenwest Pod Signal 11 00 ATTACHMENT.NO.; , Anaivsis: In 1999, the Huntington Central Park Master Environmental Impact Report (EIR) studied the development of various recreational uses within the park. The EIR contains various specialized studies that evaluated associated impacts and recommended mitigation measures. A traffic impact study was prepared for the project in accordance with the City's guidelines and is Included within the EIR. Attachment 1 shows the proposed uses within Huntington Central Park, including the proposed sports complex project. The traffic impact study evaluated the driveway access points connecting the proposed parking area for the sports complex to Golden West Street. The report recommended that the south driveway, about 1,000' south of Talbert Avenue, be restricted to right turns only. The report recommended that the other driveway, about 700' south of Talbert Avenue directly opposite the driveway serving the disc golf course, be a full access driveway for the sports complex. The report found that traffic signals for vehicles and pedestrians would not be needed and should not be installed at this location only 700' away from the existing Talbert Avenue traffic signal. On October 24, 2000, the Planning Commission approved a conditional use permit and a variance for the Huntington Central Park Sports Complex project. This approval contains a number of conditions including a requirement to install a pedestrian signal on Golden West Street in the vicinity of Golden West Plaza, the walkway area between the two pairs of baseball diamonds in the sports complex (See Attachments 2 and 3). This additional condition involves a traffic engineering matter that was not evaluated a's part of the studies for the sports complex; therefore, the City's Public Works Commission should decide if a traffic signal for pedestrians is appropriate. The pedestrian traffic signal on Golden West Street is proposed to be about 2,000' north of Ellis Avenue. In this area, Golden West Street provides six traffic Manes, a landscaped median, and striped bicycle lanes in each direction.The posted speed limit is 50 miles per hour and stopping is prohibited on both sides of Golden West Street at all times (existing red curb.) Traffic signals exist on Golden West Street at Ellis Avenue to the south and at Talbert Avenue to the north. The existing equestrian center is located west of Golden West Street opposite Golden West Plaza, with the disc.golf course and proposed low intensity recreational area further to the north opposite the sports complex. - The City utilizes the guidelines contained within the State's Traffic Manual as shown in Attachment 4 to evaluate the need for traffic signals for pedestrians and vehicles. A traffic signal for pedestrians may be needed if there are fewer than 60 gaps each hour in the traffic flow, and if there are 100 or more pedestrian crossings for each of four hours or 190 or more crossings during any hour. While it is likely that there will be fewer than 60 adequate gaps in traffic flow per hour, it is very unlikely that there will be the required minimum number of pedestrian crossings under the planned development of Huntington Central Park as: --- - ---- ATTACHMENT.kO. .. 1 l. Sufficient off street parking is planned within Huntington Central Park ,e0_ $' on both sides of Golden West Street so that vehicle parking can occur 00-1-1 on the same side of Golden West Street. 2. The park uses in the sports complex in the area of Golden West Plaza should not generate pedestrian traffic to and from the existing equestrian center west of Golden West Street. In addition to these considerations, it would be.impossible to select a midblock . location for a pedestrian traffic signal that would be used by all pedestrians wanting to cross Golden West Street in this area. As.traffic signals control the adjacent intersections, pedestrian crossings of Golden West Street at any location other than In a marked crosswalk between them is considered jaywalking and is illegal.The installation of a marked crosswalk across Golden West Street by itself is not appropriate and the criteria for a pedestrian traffic signal are not met. While a pedestrian traffic signal on Golden West Street at Golden West Plaza is not recommended, we believe that other measures should be considered to discourage random pedestrian crossings of Golden West Street in this area. In addition to the proposed landscaping, a 4' weatherized fence should be Installed in the sports complex along the west side of the meandering walkway. This will serve to keep young children within the sports complex area and will discourage random potential midblock pedestrian crossings of six lanes of high- speed trafflc.on Golden West Street.

The City shall install a signalized pedestrian crosswalk on Goldenwest Street near Goldenwest Plaza. The signal shall remain green for north and southbound traffic on Goldenwest Street unless crossing is required by pedestrians. It is within the proper purview of the Public Works Commission to request that the City Council refer this item to the Commission for consideration and action. At its October 24 meeting, the Planning Commission approved the Conditional Use Permit for the Huntington Central Park Sports Complex on Golden West Street north of Ellis Avenue. The approval added an amendment to the CUP, requiring the installation of a traffic signal for pedestrian crossings of Golden West Street between Ellis Avenue and Talbert Avenue. This recommendation involves a traffic engineering matter, which was not evaluated as part of the studies for the sports complex; therefore, the City's Public Works Commission should decide if a traffic signal for pedestrians is appropriate. The Public Works Department will evaluate the Planning Commission's recommendation on the traffic signal, as well as other alternative solutions and present its findings to the Public Works Commission at its next meeting at 5:00 p.m. on November 15, 2000.

PROJECT PROPOSAL: Applicant: Ron Hagan, Community Services Department, 2000 Main Street, Huntington Beach, CA 92648 PL00-70 -3- 11/30/00 3:54 PM REQUEST FOR ACTION MEETING DATE: December 18, 2000 DEPARTMENT ID NUMBER: PL00-70 Location: South side of Talbert, between Goldenwest Street and Gothard Street (in Central Park) Conditional Use Permit No. 00-60 represents a request for the following: A. To construct a sports complex on a 45-acre site pursuant to Section 213.06, Open - _Space District Land-Use Controls of the Huntington Beach Zoning and Subdivision Ordinance (HBZSO). B. To allow development on a site with greater than a three (3) foot grade differential between the low point and high point pursuant to Section 230.70 of the HBZSO. C. To allow walls and fences up to a maximum height of 30.feet in lieu of 3.5 feet within the front, interior side, and rear yards pursuant to Section 230.88(A)(11) of the HBZSO. Variance No. 00-24 is a request to allow a 20-foot landscaped setback in lieu of 25 feet for an 85-foot portion along Gothard pursuant to Sections 241.04 and 213.08 of the HBZSO. The sports complex is proposed to have the following amenities: a) Eight lighted softball fields overlaid-with eight soccer fields; b) Two 1,680 square foot, 25.5 feet high concession stands/restroom buildings; c) One 900 square foot, 13.5 feet high maintenance building; d) Two tot lots with play equipment for children 2-5 years old and 5-12 years old; e) An 858 space parking lot with two pick-up/drop-off areas These facilities will be operated by the City from approximately 4:00 p.m. to 10:30 p.m. Monday through Friday and 8:00 a.m. to 10:30 p.m. Saturday and Sunday for league play. It is possible that the fields may also be used during the day Monday through Friday by reservation through the City. The maintenance building will be used to store trap fencing, chalk dust and other maintenance items needed for the Sports Complex. At a later phase, four roller hockey rinks and one batting cage run by concessionaires are anticipated. These uses will be subject to approval of a separate entitlement. The applicant has indicated that the request is necessary because there is an insufficient number of sports fields to serve the growing number of youth and adults participating in sports programs within the city. B. BACKGROUND In 1997, the City Council approved the Sports Complex Master Plan. In August 1999, the EIR was certified by City Council. Authorization to prepare plans and specifications was given by the City Council in November 1999. PL00-70 -4- 11/30/00 3:54 PM i REQUEST FOR ACTION MEETING DATE: December 18, 2000 DEPARTMENT ID NUMBER: PL00-70 C. PLANNING COMMISSION MEETING AND RECOMMENDATION: On October 24, 2000, the Planning -Commission held a public hearing on the proposed project. The applicant-spoke on behalf of the project. There were no other persons who testified .at the public hearing (ATTACHMENT NO. 6). Following the public hearing and -discussion, the- Planning Commission approved the request with modified conditions including the addition of condition 7(y) which requires a signalized pedestrian crosswalk on Goldenwest Street, adjacent to Goldenwest Plaza within the sports complex. D. APPEAL: On October 26, 2000, the applicant appealed the Planning Commission's action to approve the--project with=the inclusion-of condition 7(y). The appeal (ATTACHMENT NO. 4) indicates that condition 7(y) involves a traffic engineering issue. Therefore, the City's Public Works Commission should decide if a traffic signal for pedestrians is appropriate. The Public Works Commission, at their November 15, 2000 meeting, recommended that the City Council delete condition 7(y). In addition, they also recommend the addition of a four foot high continuous weatherized fence along the west side of the meandering sidewalk within the sports complex adjacent to Goldenwest Street to discourage random pedestrian crossings of Goldenwest Street in this area. E. STAFF ANALYSIS AND RECOMMENDATION: The project's environmental impacts, including traffic, access, and circulation were analyzed under Environmental Impact Report No. 99-1 which was certified by the City Council in August 1999. The EIR included a traffic study prepared in accordance with the City's guidelines which evaluated driveway access points and parking demand, among other issues. It recommended four vehicular access points as follows: • Main access off Goldenwest (± 700 feet south of Talbert Avenue) serving north and south bound traffic. This driveway is directly opposite the driveway serving the disc golf course and includes a landscaped median; • Secondary access off Goldenwest (± 1000 feet south of Talbert Avenue) serving northbound traffic only; • Secondary access off the existing Talbert Avenue cul-de-sac west of the library; • And secondary access off the existing Talbert Avenue cul-de-sac to the east of the library. The traffic study found that traffic signals for vehicles and pedestrians are not warranted at either driveway locations along Goldenwest. Presently, pedestrians can cross Goldenwest Street at Ellis Avenue and Talbert Avenue next to the central library. City traffic engineering staff, in their report to the Public Works Commission (Attachment No. 7) also noted that the PL00-70 -5- 11/30/00 3:54 PM REQUEST FOR ACTION MEETING DATE: December 18, 2000 DEPARTMENT ID NUMBER: PL00-70 minimum conditions requiring a pedestrian crossing pursuant to the State's Traffic Manual are not likely to be met under the planned development of Huntington Central Park based on the following: • Adequate off street parking will-be provided within Central Park on both sides of Goldenwest (over 800 parking spaces-will be.included on the Sports Complex.site with two drop-off areas on site). ` • The uses in the sports complex should not generate pedestrian traffic to and from the existing equestrian center on the west side of Goldenwest Street. In lieu of installing an unwarranted signalized pedestrian crossing, both the Public Works Commission and staff recommend the addition of a four foot high continuous weatherized fence along the west side of the meandering sidewalk within the sports complex adjacent to Goldenwest Street. The-fence in conjunction with the_landscape slope-along Goldenwest should discourage random pedestrian crossings of Goldenwest Street and instead direct pedestrians to the existing signalized crosswalks at Talbert and Ellis Avenue. Environmental Status: This project was analyzed under Final Environmental Impact Report No. 99-1 which was certified by the City Council in August 1999. All applicable mitigation measures from the EIR have been included in the recommended conditions of approval.

Geology 2: Prior to circulation of plans and specifications for construction of the Sport Complex element of the proposed Master Plan,the City of Huntington Beach shall undertake sufficient engineering analysis to specify earthwork techniques to mitigate for the presence of peat, alluvial, and colluvial soils. The potential to design structures to accommodate the potential settlement resulting from compression of those materials shall be considered. Alternatively, compressible soils may be removed and replaced with engineered fill that is less compressible or is reworked during grading to reduce compressibility. Other construction techniques such as dynamic compaction, compaction grouting, or vibro flotation/replacement can be used to improve the materials in situ(i.e.,in place) so that they are not as susceptible to compression. (Mitigation Measure) o. Geology 5: The City of Huntington Beach will include in the plans and specifications for the Sports Complex element of the proposed Master Plan the need to remove collapsible materials prior to construction of any structures or pavement. The City will also include in the plans and specifications for the Sports Complex element of the proposed Master Plan the need to reduce the potential for damage from expansive soils through incorporation of appropriate engineering design, and construction methods. These methods typically include either reworking the materials so that they are placed at a moisture content and density that is less susceptible to expansion or treatment of the expansive soils with lime to stabilize them. (Mitigation Measure) p. Geology 6: The City shall include in the plans and specifications for the Sports Complex element of the proposed Master Plan the need to incorporate appropriate design and construction measures related to correction of corrosive soils' potential to corrode ferrous materials through: (Mitigation Measure) • Proper selection of construction materials • Cathodic protection, including sacrificial rods or materials • Removal of the corrosive materials adjacent to the ferrous materials and replacement with non- corrosive soils • Concrete elements that will be in contact with potentially corrosive materials can be designed using special cement that is more resistant to corrosion q. Geology 7:The City will include in the plans and specifications for all project level elements requiring imported fill material,the need for soils brought on-site to comply with City Specification 429 and as such,these activities would be subject to review and approval by the City's Fire Department. (Mitigation Measure) r. Water 1: The City will require that project design of the Sport Complex will be undertaken to ensure that there is no substantial increases in the rate and amount of surface runoff. Incidental drainage will be routed off of the site to the existing storm drains to the north and west. It is assumed that improvements to the existing storm drain system will be completed before project completions, as described in Measure Utitlities-3. (Mitigation Measure) s. Water 2: The construction Contractor will be required to incorporate Best Management Practices (BMPs)consistent with the guidelines provided in the California Storm Water Best Management (OOSR66)- 10/24/00 Attachment No. 1.6 Practice Handbooks for Construction and Industrial/Commercial Activities, and Appendices F and • G of the DAMP. Revegetation of cut and fill slopes resulting from project development will be undertaken with\native vegetation or compatble non-invasive drought tolerant species wherever feasible. Compliance with this mitigation measure shall be demonstrated prior to issuance of. grading permits or building permits,whichever comes first. (Mitigation Measure) t. Water 3: The construction manager will be required to incorporate City Ordinance No. 3364 entitled"Storm Water and Urban Runoff Management" and BMPs consistent with the guidelines' provided in the California_Storm Water Best Management Practice Handbooks: Municipal to ensure control of flood hazards and water quality prior to issuance of grading permits or building permits, whichever comes first. (Mitigation Measure) u. Hazards 11: The City Fire Department will prepare a Fire Risk Evaluation prior to issuance of grading permits. (Mitigation Measure) v. Hazards 15: Prior to construction of the Sports Complex, the City of Huntington Beach Fire Department and Public Works Department shall review all construction plans and specifications to ensure that the specifications require that each contractor involved in grading activities develop a site,and action-specific comprehensive Health.and Safety Plan. The plans and specifications will require that the Health and Safety Plan be developed using the information available about past uses of those sites and the possibility that solid waste, PCH-contaminated soils, and/or potentially hazardous waste materials could be encountered.,(Mitigation Measure) w. The City of Huntington Beach shall incorporate the findings and recommendations of the geotechnical report into the plans and specifications for the sports complex. 3. Prior to submittal for building permits,the following shall be completed: a.

Traps used to remove cowbirds will be modified Australian crow traps. These traps allow live capture of birds so that non-target birds can be released unharmed. The traps will be baited with live juvenile or female brown-headed cowbirds which will be captured prior to the trapping period with baited traps or mist nets. The juvenile or female cowbirds attract the attention of adult birds and lure them into traps. Once inside the trap, it is difficult for the birds to escape and they can be easily removed. Approximately four bait birds are kept in a separate cage within the trap and are not removed until the trapping season is over. The traps will be placed and maintained so as to provide trapped and bait birds ample shade, food,and water while they are in traps. All cowbirds(male, female, and juvenile) that are caught in the traps will be disposed of humanely. Trapping will take place during the nesting period of riparian bird species found in Central Park that are known to be parasitized by brown-headed cowbirds. Traps will be checked daily during the trapping period to remove.both trapped cowbirds and non-target species,which will be released. Bait birds lost to predation or escape will be replaced during the daily checks. An annual letter report documenting the results of the trapping program will be submitted to the US Fish and Wildlife Service. Results of the trapping-program will be recorded including the date and time of trap checking,observer(s),weather, age of trapped buds(both target and non-target species), treatment of the birds(whether released, disposed of, or retained as bait birds), and other data pertaining to any unusual event, such as predation or loss of bait birds.

[Senior Planner Mary Beth Broeren presented slide report] [Discussion held re; Measure C vote in 1996] [Approved 5-2 (Boardman, Cook No)] Staff Recommendation ATTACHMENT NO. 2 FINDINGS AND CONDITIONS OF APPROVAL CONDITIONAL USE PERMIT NO. 00-60/VARIANCE NO. 00-24 FINDINGS FOR CEOA: The Planning Commission finds that this project was analyzed under Final EIR No. 99-1 certified by the City Council in August 1999. All applicable mitigation measures identified in Final EIR No. 99-1 are included in the conditions of approval. FINDINGS FOR APPROVAL - CONDITIONAL USE PERMIT NO. 00-60: 1. Conditional Use Permit No. 00-60 to: a) construct a sports complex on a 45-acre site; b) allow development on a site with greater than a three foot grade differential between the low point and high point; c) allow walls and fences up to a maximum height of 30 feet in lieu of 3.5 feet high within the front, interior side, and rear yards; specifically 1) an eight foot high wall along Goldenwest Street at the main driveway; 2) a four foot high tubular fence along Gothard Street; 3) an eight foot high wall along the south boundary next to the mobile home park; 4) a 30 foot high backstop along the south lot line; and 5) a four foot high fence along Goldenwest Street will not be detrimental to the general welfare of persons working or residing in the vicinity or detrimental to the value of the property and improvements in the neighborhood. The sports complex will improve a vacant site with an attractive facility, which incorporates quality landscaping, as well as attractive public plazas,project monumentation, and concession/restroom buildings. It will provide much needed sports facilities for use by participants in various city sports programs. All the proposed walls within the required setback.areas serve to protect the users of the sports complex as well as the surrounding uses. Adequate parking for the use is provided entirely on site. 2. The conditional use permit will be compatible with surrounding uses because the sports complex is an extension of the character and purpose.of Central Park to provide park and recreation amenities to citizens as well as visitors. Mitigation measures have been incorporated into the design to reduce potential impacts to a level that is less than significant, including restrictions on use and lighting. A significant setback and privacy wall are provided for the abutting mobile home park. Substantial landscaped setbacks along all street frontages will provide an attractive and.pleasing buffer.

The granting of Variance No. 00-24 to allow a 20 foot landscaped setback in lieu of 25 feet for an 85 foot portion along Gothard to allow the installation of built-in bleachers will not constitute a grant of special privilege inconsistent with limitations upon other properties in the vicinity and under an identical zone classification. Other properties in the city have been granted variances for minor landscaped setback encroachments similar to that proposed for this project. The project overall exceeds all other landscaping requirements including percentage of landscaping provided at 47 percent.where only eight percent is required. 2. Because of special circumstances applicable to the subject property, including size and shape, the strict application of the zoning ordinance is found to deprive the subject property of privileges enjoyed by other properties in the vicinity and under identical zone classification..The site has an odd shaped north boundary which restricts the layout of the sports fields. Approval of the variance will allow bleachers to be provided along the Gothard Street frontage at a landscaped setback of 20 feet in lieu of 25 feet. Attachment No.2.2 3. The granting of a variance is necessary to preserve the enjoyment of one or more substantial property rights. Approval of the variance will allow for an efficient use of the site by providing the maximum number of sports fields with all the requisite amenities such as bleachers. 4. The granting of the variance will not be materially detrimental to the public welfare or injurious to property in the same zone classification. The variance represents a minor reduction in the required 25 foot landscaped setback along Gothard Street down to 20 feet for only an 85 foot portion of the entire 630 foot frontage along Gothard. Overall landscaping percentage (47 percent provided where minimum 8 percent is required) as well as tree count for the project significantly exceeds the minimum code requirements. 5. The granting of the variance will not adversely affect the General Plan. It is consistent with the Land Use Element designation of OS-P (Open Space-Park) on the subject property which permits the proposed sports complex.

The brown- headed cowbird trapping program will be submitted to the US Fish and Wildlife Service for review and comment at least three months prior to the beginning of grading. Traps used to remove cowbirds will be modified Australian crow traps. These traps allow live capture of birds so that non-target birds can be released unharmed. The traps will be baited with live juvenile or female brown-headed cowbirds which will be captured prior to the trapping period with baited traps or mist nets. The juvenile or female cowbirds attract the attention of adult birds and lure them into traps. Once inside the trap, it is difficult for the birds to escape and they can be easily removed. Approximately four bait birds are kept in a separate cage within the trap and are not removed until the trapping season is over. The traps will be placed and maintained so as to provide trapped and bait birds ample shade, food, and water while they are in traps. All cowbirds (male, female, and juvenile) that are caught in the traps will be disposed of humanely. Trapping will take place during the nesting period of riparian bird species found in Central Park that are known to be parasitized by brown-headed cowbirds. Traps will be checked daily during the trapping period to remove both trapped cowbirds and non-target species, which will be released. Bait birds lost to predation or escape will be replaced during the daily checks. An annual letter report documenting the results of the trapping program will be submitted to the US Fish and Wildlife Service. Results of the trapping program will be recorded including the date and time of trap checking, observer(s), weather, age of trapped birds (both target and non-target species), treatment of the birds (whether released, disposed of, or retained as bait birds), and other data pertaining to any unusual event, such as predation or loss of bait birds.

The City shall install a signalized pedestrian crosswalk on Goldenwest Street near Goldenwest Plaza. The signal shall remain green for north and southbound traffic on Goldenwest Street unless crossing is required by pedestrians. It is within the proper purview of the Public Works Commission to request that the City Council refer this item to the Commission for consideration and action. 4 At its October 24 meeting, the Planning Commission approved the Conditional Use Permit for the Huntington Central Park Sports Complex on Golden West Street north of Ellis Avenue. The approval added an amendment to the CUP, requiring the installation of a traffic signal for pedestrian crossings of Golden West Street between Ellis Avenue and Talbert Avenue. This recommendation involves a traffic engineering matter,which was not evaluated as part of the studies for the sports complex, therefore, the City's Public Works Commission should decide if a traffic signal for pedestrians is appropriate. The Public Works Department will evaluate the Planning Commission's recommendation on the traffic signal, as well as other alternative solutions and present its findings to the Public Works Commission at its next meeting at 5:00 p.m.on November 15, 2000. = BF.jm c: Community Services Commission Public Works Commission Robert F.

It is possible that the fields may also be used during the day Monday through Friday by reservation through the City. The maintenance building will be used to store trap fencing, chalk dust and other maintenance items needed for the Sports Complex. At a later phase, four roller hockey rinks and one batting cage run by concessionaires are anticipated. These uses will be subject to approval of a separate entitlement. The applicant has indicated that the request is necessary (Attachment No. 3)because there is an insufficient number of sports fields to serve the growing number of youth and adults participating in sports programs within the city. Background: In 1997,the City Council approved the Sports Complex Master Plan. In July 1999, the Planning Commission recommended approval of the Central Park EIR No. 99-1.

Staff Report- 10/24/00 5 (OOSR66) i Environmental Status: This project was analyzed under Final Environmental Impact Report No. 99-1 which was certified by the City Council in August 1999. All applicable mitigation measures from the EIR have been included in the recommended conditions of approval. Coastal Status:Not applicable. Redevelopment Status:Not applicable. Design Review Board.- On June 15, 2000,the Design Review Board(DRB)reviewed and recommended approval of the design, colors, and materials for the project as proposed. Staff agrees with the DRB's action. The DRB recommends that any substantive change to the plans be referred back to them for review. Subdivision Committee: Not applicable. Other Departments Concerns: Concerns from the Public Works Department are incorporated into the conditions of approval. Fire Department concerns are addressed by mitigation measures included in the conditions of approval. The Building Department does not have any unusual concerns other than compliance with the building code during building permit plan check. The Police Department comments that they are satisfied with the . overall design of the Sports Complex because it incorporates crime prevention principles. However,the Police Department has several recommendations one of which contradicts a recommended mitigation measure as follows: • Lighting in the parking lot and field area shall remain all night. However,the intensity of the light can be reduced dramatically after park hours. (Contradicted by Mitigation Measure Noise 2, see Condition of Approval 8d.) There will be 16 ft. high dusk to dawn walkway lighting that provides the security. lighting that the Police Department recommends throughout the Sports Complex,however,the sports lighting will be turned off. • Recommends that light placement take into consideration.parking lot trees. Staff believes that the revised planting plan for the parking lot addresses this concern. Although initially proposed to reduce costs,the revised planting plan serves the dual purpose of providing unobstructed lighting of the parking lot area by concentrating tree placement on the perimeter and in selected medians while still exceeding code requirements for trees within a parking lot. • Recommends that signage should be clear stating park and parking lot hours and that signs are clearly placed throughout the park and parking lot entrances. Staff has included a recommended condition of approval (No. 4a) for a Planned Sign Program for the Sports Complex which will address the Police Department's recommendation. 1 i ACHMENT-NO. Staff Report- 10/24/00 6 (OOSR66) Public Noti ication: Legal notice was published in the Huntington Beach/Fountain Valley Independent on Thursday October 12, 2000. Notices were sent to property owners of record within a 300 ft. radius of the subject property, occupants of the adjacent city owned mobile home park,persons who participated in the EIR process, individuals/organizations requesting notification(Planning Department's Notification Matrix), sports groups,homeowner's associations in the area, applicant, and interested parties. As of October 19,2000 no communication supporting or opposing the request has been received. Application Processing Dates: DATE OF COMPLETE APPLICATION: MANDATORY PROCESSING DATE(S): CUP and VAR: October 8, 2000 Within 60 days of environmental determination and complete application: December 8, 2000 ANALYSIS: The primary issues with the sports complex include compatibility, site layout and design, circulation,the various proposed fences and walls, and the variance request. Compatibility The proposed sports complex is an appropriate use for the site based on its current General Plan Land Use and zoning designation of Open Space-Park. It represents an extension of the character and purpose of the Central Park to provide park and recreation facilities for our citizens as well as visitors. The site itself is isolated from most sensitive uses. Located to the north is the central library, central park, and an oil yard, while to the south is a city-owned mobile home park and a former county transfer station. Located to the west is Goldenwest Street with the remainder of central park beyond it,while to the east is the rest of the county transfer station,the closed gun range,and Sully Miller Lake. The adjacent mobile home park to the south will be buffered from the sports complex through a substantial setback and an eight(8)foot high block wall for privacy and aesthetics. Pursuant to recommended mitigation measures,the southwest .. fields will be closed by 10:00 p.m., amplified announcements will be restricted and sports lighting will be shielded to address noise and other aesthetic concerns. In addition to the shielding, sports lighting will be 60-80 feet high in order to maximize the aiming angle and minimize spill light. The site itself will be graded to allow proper drainage while achieving compatibility with the surrounding area to the greatest extent feasible. Due to the nature of the uses surrounding the proposed complex coupled with substantial landscaped setbacks, attractive project design and amenities, and the application of all appropriate mitigation measures identified in Final EIR No. 99-1,the project will be compatible with the area. Site Layout and Design Site layout, design, and site enhancements were influenced by various concerns including compatibility, aesthetics, crime prevention principles, long-term operation and maintenance, and environmental concerns. As previously analyzed as part of the EIR certification process, a portion of the site is underlain ATTACHMENT NO, - Staff Report- 10/24/00 7 (OOSR66) by a former landfill. In order to minimize irrigation over the landfill,the parking lot was located over this area and the fields were located outside of the landfill. This also centrally locates the parking area for the southwest fields along Goldenwest and the northeast fields adjacent to Gothard and Talbert. To maximize use of the non-landfill area the softball fields overlap the soccer fields. Soccer play is.only expected six weeks a year with the majority of the activity being for softball. Two public plazas are proposed, one off Goldenwest and another off Talbert. Goldenwest plaza includes a concession/restroom building, a tot lot,walkway system with decorative paving, and other amenities such as decorative seat walls,benches,tables,bike racks and drinking fountains. Users can walk past the plaza onto a promenade that leads to the rear of the site and onto the rest of the walkway system which loops around and through the complex. The promenade will have decorative paving as well as landscaping and build-in bleachers on both sides for viewing and is highlighted by a decorative landscape planter located at its east end. Talbert plaza includes the same amenities. Both concession/restroom buildings have storage area and two concession windows and are oriented such that the restrooms face the tot lots to allow parents to view children at all times. The overall concept used for building design and colors/materials selection is to have a more natural appearance in keeping with the character of central park. The two concession/restroom buildings have a maximum height of 25.5 feet at the tower element with the majority of the building at a height of 16 feet. The buildings include adequate variation in roofline and bulk which when combined with the variety of exterior materials (stucco,river rock,wood rafters and accent posts, standing seam metal roofing, and "dancing"ceramic tile)makes for an attractive design. The color scheme includes various shades of green to blend in with the landscaping. The maintenance building is proposed to be of corrugated metal siding with standing seam metal roof to match the concession building. It is located toward the rear of the site and will be screened with landscaping. Other site enhancements are proposed to promote a fun sports-theme atmosphere. The monumentation at the main entry off Goldenwest is proposed to have metal sports figure cutouts, ornamental metal cap, "dancing tile"to match the concession buildings, and decorative spheres. The seat walls will have recessed words that inspire excitement while the backstops will have snap on links that will be configured into the shape of sports figures. Combined the various site enhancements form the public art component of the project providing a unifying playful sports theme throughout the project site. Circulation Provisions for adequate pedestrian and vehicular circulation are incorporated into the sports complex plan. Vehicular access is provided at four points as follows: • Main access off Goldenwest,north and south bound traffic,with landscaped median; • Secondary access off Goldenwest,northbound traffic only, south of the main access; • Secondary access off the existing Talbert Avenue cul-de-sac west of the library; • And secondary access off the proposed Talbert Avenue cul-de-sac to the east of the library ATTACHMENT NO. Staff Report- 10/24/00 8 (OOSR66) C Access to the project is deemed adequate as reviewed by staff and analyzed in the Final EIR. All four access points channel vehicles directly to a well laid out and heavily landscaped and paved non-metered parking lot which exceeds the required number of spaces in the EIR by 76 parking spaces. The parking lot itself has adequate and logical circulation. Two drop off points are proposed within the parking lot next to the sports fields. Landscaping in the parking lot has been scaled back from that presented to the Design Review Board due to cost. Instead, Community Services proposes sections of the parking lot with landscape islands at the end of parking rows but no trees within the rows. The two pedestrian walkways that traverse the parking lot would remain fully landscaped. The longest row of parking without a landscape break is 38 spaces. This revised landscaping plan is similar to the plan approved for the South Beach parking lot and would allow sections of the parking lot to more easily accommodate buses. The parking lot would still far exceed the City's requirement for parking lot trees,providing almost twice the required number of trees. There is also significant planting along the perimeter of the parking lot which further helps to screen the lot from Goldenwest and Talbert. A walkway system is proposed to allow effective access of the sports complex from the surrounding area including central library to the north. From the parking lot,users can access the sports fields through a system of five foot wide decomposed granite walkways located in the center of several rows of parking spaces. The decomposed granite walkways are purposely designed to maintain the natural appearance of the area while requiring minimal maintenance. Along Goldenwest, a meandering ten foot wide walkway is proposed while along Gothard and Talbert, a six foot wide sidewalk will provide adequate pedestrian circulation. Access to the interior and rear of the sports complex will be via a system of ten foot wide decomposed granite pathways that allow users to effectively walk from one end of the complex to the other. These pathways may also be used by maintenance and emergency vehicles. Pedestrian access for the project, like vehicular access, is more than adequate. Fences and Walls A variety of walls and fences are proposed as outlined in the zoning compliance matrix section of the report. The majority comply with setback requirements and are permitted by code. However, a few do not comply with setback requirements and therefore require approval of a Conditional Use Permit(CUP) to review compatibility and appropriateness of design. Along Goldenwest Street,the plans show an eight foot high main entry wall and a 30 foot high chain link back stop. The 30 foot high back stop will be setback 88 feet(minimum 25 foot setback required) along Goldenwest and will be softened by landscaping. -The main entry wall will have a landscaped setback of ten feet at the closest point in lieu of the minimum 25 feet and therefore requires approval of a CUP. Staff supports this entry wall because it is decorative and is part of an overall design concept which includes enhanced paving and accent landscaping to clearly identify the main entrance. It complies with the required corner visibility cutoff and should not be detrimental. Along Gothard Street,the plans show a six foot high tubular fence, a 30 foot high chain link back stop as well as a 30 foot high soccer barrier offset from the backstop. The 30 foot high backstop/barrier will have a 31.5 foot landscaped setback off Gothard to soften its appearance. The six foot high tubular fence is proposed on the lot line next to the sidewalk along Gothard in lieu of the 25 foot setback and therefore AT eMCHMENT NO. . Staff Report- 10/24/00 9 (OOSR66) requires a CUP. It is intended to prevent kids from running onto the street from the bleachers. Staff supports this fence with a condition to lower its height to 4.0 feet so as not to be as imposing next to the sidewalk while still serving its purpose. Along Talbert Avenue, a 30 foot high chain link back stop is proposed at a setback of about 40 feet. It. complies with code and will be softened by landscaping. Along the rear(east)property line, a six foot high vinyl coated chain link fence as well as a 30 foot high back stop are proposed. These barriers comply with height limitations and setback requirements. Because of this and their location interior to the site,there are no concerns from staff. Finally, along the south lot line,next to the city-owned mobile home park plans call for an eight foot high block wall located within the 25 foot interior side yard as well as a 30 foot high backstop that complies with the interior side yard setback.. Staff supports the eight foot high block wall because it will provide buffering for the mobile home park. Along the south lot line to the east of the site and next to the former transfer station, a 30 foot high back stop within the 25 foot interior side yard and a six foot high vinyl coated chain link fence within the 25 foot setback along Gothard are proposed. Staff supports both because they have safety benefits but recommends that the six foot vinyl clad chain link fence be reduced to 3.5 feet high within the 25 foot setback along Gothard to comply with code. Variance Staff recommends that the landscaped setback variance along Gothard Street be approved. The variance represents a minor reduction in the landscaped setback of five feet(20 feet proposed where 25 feet is required) and only for an 85 foot segment of the entire 630 foot Gothard frontage. The variance will allow the installation of built-in bleachers next to a softball field. The project overall exceeds all other landscaping requirements including amount of landscaping(47 percent proposed cdmpared to 8 percent required) and trees proposed. Due to the odd configuration of the north site boundary, it would be a hardship to shift the play fields west to comply with code while still maximizing use of the site. ATTACHMENTS: 1. Suggested Findings and Conditions of Approval 2. , 3. Narrative SH:MBB:RR:rl ATTACHMENT NO. Staff Report- 10/24/00 10 (OOSR66) ATTACHMENT NO. 1 SUGGESTED FINDINGS AND CONDITIONS OF APPROVAL CONDITIONAL USE PERMIT NO. 00-60/VARIANCE NO. 00-24 SUGGESTED FINDINGS FOR CEQA: The Planning Commission finds that this project was analyzed under Final EIR No. 99-1 certified by the City Council in August 1999. All applicable mitigation measures identified in Final EIR No. 99-1 are included in the conditions of approval. SUGGESTED FINDINGS FOR APPROVAL-CONDITIONAL USE PERMIT NO. 00-60: 1. Conditional Use Permit No. 00-60 to: a) construct a sports complex on a 45-acre site; b) allow development on a site with greater than a three foot grade differential between the low point and high point; c) allow walls and fences up to a maximum height of 30 feet in lieu of 3.5 feet high within the front, interior side, and rear yards; specifically 1) an eight foot high wall along Goldenwest Street at the main driveway; 2)a four foot high tubular fence along Gothard Street; 3) an eight foot high wall along the south boundary next to the mobile home park; and 4)a 30 foot backstop along the south lot line will not be detrimental to the general welfare of persons working or residing in the vicinity or detrimental to the value of the property and improvements in the neighborhood.' The sports complex will improve a vacant site with an attractive facility,which incorporates quality landscaping, as well as attractive public plazas,project monumentation,and concession/restroom buildings. It will provide much needed sports facilities for use by participants in various city sports programs. All the proposed walls within the required setback areas serve to protect the users of the sports complex as well as the surrounding uses. Adequate parking for the use is provided entirely on site. 2. The conditional use permit will be compatible with surrounding uses because the sports complex is an extension of the character and purpose of Central Park to provide park and recreation amenities to citizens as well as visitors. Mitigation measures have been incorporated into the design to reduce potential impacts to a level that is less than significant, including restrictions on use and lighting. A significant setback and privacy wall are provided for the abutting mobile home park. Substantial landscaped setbacks along all street frontages will provide an attractive and pleasing buffer. The site will be graded to allow proper drainage while achieving compatibility with the surrounding area to the greatest extent feasible. 3. The proposed project will comply with the provisions of the base district and other applicable provisions in Titles 20-25 of the Huntington Beach Zoning and Subdivision Ordinance, as well as any " specific condition required for the proposed use in the district in which it would be located, except for (OOSR66)- 10/24/00 Attachment No. 1.1 any variances approved concurrently. The project meets or exceeds all minimum development requirements including setbacks for the buildings, landscaping,parking, and site coverage among others. 4. The granting of the conditional use permit will not adversely affect the General Plan. It is consistent with the Land Use Element designation of OS-P (Open Space-Park) on the subject property which permits parks and recreation facilities. In addition, it is consistent with the following goals and policies of the General Plan: a. LU 4 -Achieve and maintain high quality architecture, landscape, and public open spaces in the City. b. LU 14.1.1 -Accommodate the development of public parks . . . in areas designated for Open Space on the Land Use Plan Map. c. LU 14.1.3 -Require that structures located in the City's parks and other open spaces are designed to maintain the environmental character in which they are located. d. RCS 1 -Enrich the quality of life for all citizens of Huntington Beach by providing constructive and creative leisure opportunities. e. RCS 1.1.4 -Encourage and facilitate the development of a wide variety of revenue generating recreational activities such as corporate picnic facilities,wedding facilities, infant, child, or senior day care, fishing facilities, golf courses,ranges,batting cages,roller hockey, sports fields, etc. . f. RCS 3 -Develop park sites to provide diverse recreational and sports facilities that meet the residents' and visitors' active and passive recreational needs. g. RCS 3.1.3 -Develop public parks and recreation facilities that link trails and existing recreational facilities. SUGGESTED FINDINGS FOR APPROVAL-VARIANCE NO. 00-24: 1. . The granting of Variance No. 00-24 to allow a 20 foot landscaped setback in lieu of 25 feet for an 85 foot portion along Gothard to allow the installation of built-in bleachers will not constitute a grant of special privilege inconsistent with limitations upon other properties in the vicinity and under an identical zone classification. Other properties in the city have been granted variances for minor landscaped setback encroachments similar to that proposed for this project. The project overall exceeds all other landscaping requirements including percentage of landscaping provided at 47 percent where only eight percent is required. 2. Because of special circumstances applicable to the subject property, including size and shape,the strict application of the zoning ordinance is found to deprive the subject property of privileges enjoyed by other properties in the vicinity and under identical zone classification. The site has an odd shaped kVIL-NT NO, (OOSR66)- 10/24/00 Attachment No. 1.2 north boundary which restricts the layout of the sports fields. Approval of the variance will allow bleachers to be provided along the Gothard Street frontage at a landscaped setback of 20 feet in lieu of 25 feet. 3. The granting of a variance is necessary to preserve the enjoyment of one or more substantial property rights. Approval of the variance will allow for an efficient use of the site by providing the maximum number of sports fields with all the requisite amenities such as bleachers. 4. The granting of the variance will not be materially detrimental to the public welfare or injurious to property in the same zone classification. The variance represents a minor reduction in the required 25 foot landscaped setback along Gothard Street down to 20 feet for only an 85 foot portion of the entire 630 foot frontage along Gothard. Overall landscaping percentage (47 percent provided where minimum 8 percent is required)as well as tree count for the project significantly exceeds the minimum code requirements. 5. The granting of the variance will not adversely affect the General Plan. It is consistent with the Land Use Element designation of OS-P (Open Space-Park)on the subject property which permits the proposed sports complex.

Geology 1: The City of Huntington Beach shall incorporate the following recommendations into Plans and Specifications for the Sports Complex element of the proposed Master Plan for the proposed project as a means of reducing the effects of expected ground surface settlements on the proposed improvements: (Mitigation Measure) • For environmental compliance,maintaining at least a 6-foot thick layer of cover soils over the refuse;this would require special permitting from the Regional Water Quality Control Board (RWQCB) as a monolithic cover system • Pre-loading areas where structures are planned to reduce the elastic component of the refuse settlement • In-situ improvement of the upper portions of the refuse through the use of dynamic compaction (OOSR66)- 10/24/00 Attachment No. 1.5 • Including a synthetic reinforcement material in the 6-foot thick cover soil layer to create a stiff layer of soil capable of supporting structures and tending to distribute the effects of differential settlement n. Geology 2: Prior to circulation of plans and specifications for construction of the Sport Complex element of the proposed Master Plan,the City of Huntington Beach shall undertake sufficient engineering analysis to specify earthwork techniques to mitigate for the presence of peat,alluvial, and colluvial soils. The potential to design structures to accommodate the potential settlement resulting from compression of those materials may be considered. Alternatively, compressible soils may be removed and replaced with engineered fill that is less compressible or is reworked during grading to reduce compressibility. Other construction techniques such as dynamic compaction, compaction grouting, or vibro Rotation/replacement can be used to improve the materials in situ(i.e., in place) so that they are not as susceptible to compression. (Mitigation Measure) o. Geology 5: The City of Huntington Beach will include in the plans and specifications for the Sports Complex element of the proposed Master Plan the need to remove collapsible materials prior to construction of any structures or pavement. The City will also include in the plans and specifications for the Sports Complex element of the proposed Master Plan the need to reduce the potential for damage from expansive soils through incorporation of appropriate engineering design, and construction methods. These methods typically include either reworking the materials so that they are placed at a moisture content and density that is less susceptible to expansion or treatment of the expansive soils with lime to stabilize them. (Mitigation Measure) p. Geology 6: The City shall include in the plans and specifications for the Sports Complex element of the proposed Master Plan the need to incorporate appropriate design and construction measures related to correction of corrosive soils' potential to corrode ferrous materials through: (Mitigation Measure) • Proper selection of construction materials • Cathodic protection, including sacrificial rods or materials • Removal of the corrosive materials adjacent to the ferrous materials and replacement with non- corrosive soils • Concrete elements that will be in contact with potentially corrosive materials can be designed using special cement that is more resistant to corrosion q. Geology 7: The City will include in the plans and specifications for all project level elements requiring imported fill material,the need for soils brought on-site to comply with City Specification 429 and as such,these activities would be subject to review and approval by the City's Fire Department. (Mitigation Measure) �TTACHMENTNO. !1:..,, (OOSR66)- 10/24/00 Attachment No. 1.6 C r. Water 1: The City will require that project design of the Sport Complex will be undertaken to ensure that there is no substantial increases in the rate and amount of surface runoff. Incidental drainage will be routed off of the site to the existing storm drains to the north and west. It is assumed that improvements to the existing storm drain system will be completed before project completions, as described in Measure Utitlities-3. (Mitigation Measure) s. Water 2: The construction Contractor will be required to incorporate Best Management Practices (BMPs) consistent with the guidelines provided in the California Storm Water Best Management Practice Handbooks for Construction and Industrial/Commercial Activities, and Appendices F and G of the DAMP. Revegetation of cut and fill slopes resulting from project development will be undertaken with native vegetation or compatible non-invasive drought tolerant species wherever feasible. Compliance with this mitigation measure shall be demonstrated prior to issuance of grading permits or building permits,whichever comes first. (Mitigation Measure) t. Water 3: The construction manager will be required to incorporate City Ordinance No. 3364 entitled"Storm Water and Urban Runoff Management" and BMPs consistent with the guidelines provided in the California Storm Water Best Management Practice Handbooks: Municipal to ensure control of flood hazards and water quality prior to issuance of grading permits or building permits, whichever comes first. (Mitigation Measure) u. Hazards 11: The City Fire Department will prepare a Fire Risk Evaluation prior to issuance of grading permits. (Mitigation Measure) v. Hazards 15: Prior to construction of the Sports Complex, Park, Tree and Landscape Maintenance Yard Expansion, Consolidated Camping Area, and Low-Intensity Recreation elements of the Master Plan,the City of Huntington Beach Fire Department and Public Works Department shall review all construction plans and specifications to ensure that the specifications require that each contractor involved in grading activities develop a site-and action-specific comprehensive Health and Safety Plan. The plans and specifications will require that the Health and Safety Plan be developed using the information available about past uses of those sites and the possibility that solid waste, PCH-contaminated soils, and/or potentially hazardous waste materials could be encountered. (Mitigation Measure) 3. Prior to submittal for building permits,the following shall be completed: a. Zoning entitlement conditions of approval shall be printed verbatim on all the working drawing sets used for issuance of building permits (architectural, structural, electrical,mechanical and plumbing) and shall be referenced in the index. b. Submit three (3) copies of the site plan and floor plans and the processing fee to the Planning Department for addressing purposes. c. A detailed soils analysis shall be prepared by a registered Soils Engineer and submitted with the building permit application.

A Professional Corporation 18800 Main Street, Suite 202 Huntington Beach, CA 92648 714-848-2278 C cz� c December 15, 2000 — A Re: Item D-1, Approval of Conditional Use Permit No. 00-60Nariance No. 00-24 Appeal (Huntington Central Park Sports Complex) Dear Honorable Mayor and City Council Members: ]> Although I am currently the Chairman of the Huntington Beach Planning Commission, I am writing this letter as an individual and I am only representing myself. Several weeks prior to the October 24, 2000 Planning Commission meeting, I was informed by a Huntington Beach citizen that the City had received the draft copy of the geotechnical report for the Huntington Beach Central Park Sports Complex. I was also told that it made some very strong recommendations and that it should be reviewed prior to our Planning Commission action. I requested that the Planning Commission members be given a copy in their staff reports. I was told that it,was not available because the City had returned it to the author and had not kept a copy. Staff was asked again at the Planning Commission meeting about status of the AGRA Geotechnical Report. Staff responded by stating that the report was not yet available(Attachment No. 6.2). Although we did not see the report, Condition 2.w(page D-1.13 in your staff report)was added. It states, "The City of Huntington Beach shall incorporate the findings and recommendations of the geotechnical report into the plans and specifications for the sports complex." Staff made a copy of the report available to me within the last week. I have reviewed the document and have found the findings very enlightening. I hope that the Council has been made aware of the findings and recommendations. It appears that this project will require extraordinary measures to deal with the issues of ground water contamination and subsidence. These recommendations could cause the proposed construction budget to be exceeded. I am including a copy of the November 28, 2000 Geotechnical Report for your review. It does not appear that it has been included in your packet of information. I would suggest that you at least carefully review Sections 6, 8, 9, 10, and 11. This is and extremely important project for the City of Huntington Beach. It requires complete and thorough review prior to approval. Since the Planning Commission was not able to review this document, it is imperative that the City Council does. The project is so important and the potential for huge cost overruns so great,the City Council must take all the time it needs to thoroughly understand the complexity of the commitment needed to make the Sports Complex successful as we all hope it will be. I am sorry that previous family commitments make it impossible for me to present this at the public hearing. If you have any questions, please feel free to call me at my home (842-3345)or at my office(848-2278). Thank you for your consideration.

The purpose was to: • Summarize available pertinent geotechnical and environmental information; • Present the results of supplemental investigation and engineering analyses completed by AMEC to support the design assumptions and constraints; • Provide design and construction recommendations for the proposed facilities; • Provide recommendations for construction of an alternative soil cover. • Provide geotechnical recommendations in support of the landfill gas collection system design. The recommendations for the landfill gas collection system are provided under separate cover in a report prepared by Bryan A. Stirrat & Associates (BAS) entitled "Basis Of Design Report, The Huntington Beach Sports Complex Parking, Gas Control System" and dated November 8, 2000. 1.1 PROPOSED DEVELOPMENT The proposed development site encompasses about 45 acres and will include soccer and baseball fields, roller hockey rinks(approximate footprint 180 x 90 feet), batting cage(approximately 20,000 square feet), concession, restroom, and maintenance buildings (approximate footprint of 30 x 60 feet), and paved parking areas. Roughly 2/3 of the project area was previously used as a disposal site for a variety of materials ranging from drilling mud to municipal solid waste. A more detailed site history is summarized in the Section 1.2. The facilities layout provided by NUVIS Landscape Architecture And Planning (NUVIS) indicated that the proposed development has been laid out to reflect the specific design and environmental constraints associated.with certain areas within the development. The soccer and baseball fields are planned to be located above landfill materials and above native soils relatively insensitive to percolation of irrigation water; a large paved parking lot will cover the areas where municipal refuse was disposed. Roller hockey rinks and a batting cage are proposed to be located above the municipal refuse. The proposed development has been divided into 4 areas according to the proposed facility function and type of subsurface materials. These 4 areas are shown color-coded on Plate II -Site Layout And Boring Locations Plan, and are discussed below: ame., Metropointe Engineers Job No.0-212-100600 Attention: Mr. Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach,California Page 2 Area 1: Approximately 14 acres in the northeast portion of the project site is proposed to be utilized for baseball and soccer fields, a tot lot, and a concession/restroom facility (approximate footprint of 30 x 60 feet). A retaining wall up to about 11 feet high is proposed near the tot lot. The underlying landfill materials are generally of inert nature as they are mostly construction debris-derived fill material. The western portion of this area is located within a miscellaneous landfill materials zone consisting primarily of soil and construction debris and pockets of drilling mud. The fill materials are covered by an inert soil cap of varying thickness typically greater than the 10 feet. This area is proposed to be re-graded and covered with turf in the sporting field areas or concrete pavement slab in and around the concession/ restroom and tot lot area. In order to reduce the potential for percolation of precipitation and irrigation water into the subsurface materials, an alternate soil cap will be required and designed in accordance with the requirements of California Code Of Regulations, Title 27 - Environmental Protection. Areas 2A Area 2, which is about 16 acres in size, is located in the northwest part of the and 2B: property. The northwest portion of this area is to be utilized for parking (Area 2A, about 11 acres). The remaining portion of this area is proposed to be used for sporting facilities, including four roller hockey rinks and a batting cage, maintenance building and landfill gas collection system control building, with non-irrigated xeroscape areas in between (Area 2B, about 5 acres). Subsurface materials in Area 2 consist of municipal waste deposited 40 to 50 years ago. This former landfill area is considered closed as per a letter from the Regional Water Quality Control Board (RWQCB)dated April 3, 1995. In that letter RWQCB offered its belief that the site was covered in such a manner that it met the requirements for an engineered alternative cap. Groundwater data discussed in the RWQCB letter dated May 3, 1994,noted only"slightly impacted"groundwater. The proposed construction will further improve the existing condition by limiting the infiltration of irrigation water and precipitation in the subgrade by installation of an engineered alternative soil cover. All of Area 2 will be underlain by an active landfill gas collection system. The parking lot (Area 2A) will be covered by an essentially impermeable asphalt pavement placed over a re-compacted subgrade, which will replace the existing non-engineered fill soil cap. As the proposed construction is a significant improvement of the existing "Closed Landfill" condition, no numerical modeling of the asphalt cover is deemed necessary for Area 2A. amed-Y Metropointe Engineers Job No.0-212-100600 Attention: Mr. Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach,California Page 3 The remaining area(Area 213)will be covered by the proposed facilities and by non- irrigated xeroscape. There is a possibility that the sporting facilities will be developed in a later phase and that the building pads will be temporarily exposed. The design of the cover in Area 2B will be carried out in accordance with the requirements of California Code Of Regulations,Title 27-Environmental Protection. Area 3: The southwest portion of the property(about 14 acres)is proposed to be utilized for baseball and soccer fields, and a plaza consisting of a tot lot, and a concession / restroom facility(approximate footprint of 30 x 60 feet). An abandoned oil well has been located near the proposed plaza, therefore these facilities have been configured to comply with the required 25-foot setback from the oil well. A sound wall is proposed along the south boundary of the area. Subsurface materials in Area 3 consist of localized thin veneer of inert soil fill underlain by native terrace materials. Conventional grading, foundations, and ground cover are anticipated and recommended for the improvements in this area. 1.2 SITE DESCRIPTION AND HISTORY The project area is a part of a larger site located between Golden West Street, Talbert Avenue, Gothard Street, and Ellis Avenue, in the City of Huntington Beach (see Plate II - Site Layout And Boring Locations Plan) and Plate VI. The site is shaped like an inverted letter "L" where the northwest corner coincides with the intersection of Golden West Street and Talbert Avenue (Area 2A) and the legs follow along Talbert Avenue to the east (Area 1) and along Golden West Street to the south (Area 3). The Oceanview Estates mobile home park borders the Golden West Street Area at the south and Sully Miller Lake borders the area at the east. Sully Miller Lake was created by gravel and sand mining operations. The site history has been compiled primarily from information contained in available reports (see Section 2.1). Historically, the larger site was used primarily for agriculture and livestock grazing. Pre-1950 aerial photographs and USGS topographic maps indicate that a roughly 35-foot deep channel traversed the site from the northwest corner of the property to the south. Several current use areas are identified within the project site, including the Hanson Inert Construction Debris Processing Plant and a field office for the Orange County Sewer District Golden West trunk sewer, both located along the southern limit of Area 1. The Huntington Beach Police Officer's Rifle And Pistol Range (now closed) and the Orange County Transfer Station (formerly part of the Gothard Street Landfill/Huntington Beach Landfill)border the project area to the south of the Area 1. A paved construction materials storage area is located next to the Huntington Beach Central Library parking lot on Talbert Avenue, approximately half way between ameO Metropointe Engineers Job No.0-212-100600 Attention:Mr. Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach, California Page 4 Golden West Street and Gothard Street. An area known as the Mushroom Farm is located along Golden West Street-in the vicinity of Taylor Drive at the northern limit of Area 3. A large portion of the project site consists of former municipal refuse and construction debris landfills. A review of the available information indicates no distinct boundary between the two waste types. The landfill areas extend to the north and southeast beyond the limits of the project site. Landfill areas of the larger site located between Golden West Street,Talbert Avenue,Gothard Street, and Ellis Avenue, can be generally divided into two areas: about 31 acres of mixed municipal refuse and about 15 acres of inert construction debris and miscellaneous landfill material: The 31-acre mixed municipal refuse landfill area is known as the Huntington Beach Landfill or Gothard Street Landfill (see Plate II). Of this, the northwest portion, located on the project site, was originally owned by the County of Orange and called the Golden West Street Disposal Station No. 10. The eastern portion of this landfill area is still owned by the County of Orange and is known as the Orange County Transfer Station. Initially, municipal refuse was deposited into an historic channel, which is apparent on aerial photographs referenced in the Environmental Impact Report dated February 26, 1999, (see Section 2.1), and the adjacent sand and gravel pits. The landfill accepted household trash, landscaping cuttings, and other non-hazardous organic debris. The County operated the site as a burning dump from September 1947 through September 1956. After this date the site was reportedly operated as a spread and cover operation. County records referenced in the aforementioned Environmental Impact Report indicate that approximately 1.1 million cubic yards of refuse were deposited into the site before its closure in June 1962. The 15-acre inert construction debris and miscellaneous landfill portion of the landfill is located at the southwest corner of Talbert Avenue and Gothard Street. This area was known as the Bruce Brothers Pit and was a sand mining operation prior to 1927. From 1927 to 1949 the western portion of the pit was also used as a disposal site for rotary drilling muds and waste muds from sumps. This area is designated as containing miscellaneous landfill materials on Plate II - Site Layout And Boring Locations Plan. In 1957,a permit was issued for the disposal of inert materials. In 1972, the City of Huntington Beach purchased the property and closed the pit in 1973. In October 1979, the City received a permit to operate the pit as a construction debris disposal site. Approximately 210,000 cubic yards of construction debris material had been deposited at the site between October 1979 and 1982.. Prior to and through 1993,approximately 400,000 cubic yards of silty sand dredged from the Santa Ana River bottom were placed on the project site to provide an soil cap to the landfill materials. This soil was apparently placed in a non-controlled and non-engineered manner. The project area along Golden West Street in the vicinity of Taylor Drive had been occupied by the Oceanview Mushroom Growers,with active farming production probably from the middle 1950s amee Metropointe Engineers Job No.0-212-100600 Attention: Mr.Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex,Huntington Beach,California Page 5 until the late 1980s. Shallow solid waste fills,likely related to the mushroom farm operations, have been encountered in the northeast corner of the farm. In 1993,approximately 13,000 cubic yards of hydrocarbon contaminated soil was excavated during the expansion of the library parking lot and spread over 8 acres in the former mushroom farm area. This soil was then bio-remediated to reduce the hydrocarbons concentration. It is understood that the remediation was successful and that there was a steady decline in average total petroleum hydrocarbon (TPH)concentrations to a non-detection level of<30 ppm in August 1995. Based on the 1994 GeoScience Analytical, Inc. report, the remaining hydrocarbon contaminated area in the vicinity of the library parking lot and encroaching on the project site, contains between 135,000 and 185,000 cubic yards. The Huntington Beach Police Officer's Rifle And Pistol Range, a 7.5 acre site located just to the north of Sully Miller Lake and bordering on the Area 3 of the project site, was operated from the late 1960s until January 4, 1997, when the City terminated the lease. The range has experienced substantial ground settlement from the compression of the underlying landfill materials. 1.3 SCOPE OF WORK The scope of this Geotechnical Study consisted of compilation and review of available subsurface and surface information,field investigations,soil sampling,laboratory testing,engineering analyses, formulation of design recommendations and preparation of this report. Specifically, the following tasks were completed: 1. General reconnaissance of the site and layout of boring locations; 2. Review of available information from previous investigations; 3.

(KFI)performed a Geotechnical Engineering Study(Phase I and Phase II) to evaluate the site subsurface conditions and to provide the City of Huntington Beach with information needed for recommending an appropriate final use of the landfill. KFI's drilling program covered the entire area of the proposed project site and extended into the adjacent area of the Orange County Transfer Station. The study consisted of advancing of a total of 38 borings and 44 test pits (boring and test pit locations are shown on Plate II - Site Layout And Boring Locations Plan in the back of this report, and borehole and test pit logs and laboratory test results are included in Appendix C) In 1997, CH2M.Hill excavated 18 test pits within the project area and contracted with K-Prime Geoscience, Inc. to complete geophysical seismic reflection profiles in the gun range area and in the project area along Golden West Street. (Test pit locations are shown on Plate II - Site Layout And Boring Locations Plan in the back of this report; all test pit logs and seismic profiles are included in Appendix C and Appendix D, respectively.) ame, Metropointe Engineers Job No.0-212-100600 Attention:Mr.Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach,California Page 9 3.0 SCOPE OF GEOTECHNICAL INVESTIGATION 3.1 INVESTIGATION APPROACH The previous study programs carried out by Kleinfelder and CH2M Hill are considered to constitute an adequate basis for assessment of subsurface conditions for the proposed development. Thus, this current investigation focused on subsurface conditions at the locations of proposed structures- i.e., concession buildings, roller hockey rinks and parking lot- and was undertaken to verify and complement the existing information. 3.2 FIELD INVESTIGATION The field portion of the study was carried out in two phases. The first phase occurred between March 22 and 27, 2000, when 9 borings (B-1 through B-9) were advanced. The depths of the borings varied from about 20 to 65 feet. The second mobilization on April 28, 2000 focused on investigation of the extent of hydrocarbon contaminated drilling mud zones in the vicinity of the central portion of the Central Library parking lot. A total of 7 borings (B-10 through B-16) were advanced to depths of about 15 to 20 feet. Both mobilizations utilized 8-inch diameter hollow stem auger drilling equipment. Three shallow sample pits (T-101 through T-103) were also excavated in the area of the proposed turn lane from northbound Gothard Street using a hand auger. Approximate boring locations are shown on Plate II - Site Layout And Boring Locations Plan. Details pertaining to the soils encountered and samples obtained are presented on the Test Boring Logs in Appendix A. Both bulk and relatively undisturbed samples of selected soil types were obtained from the borings for laboratory testing and visual classification. The relatively undisturbed samples were obtained with a 2.5-inch I.D. ring sampler driven with a 140-pound weight dropping 30 inches. In addition, Standard Penetration Tests were conducted in general accordance with ASTM D1586 by driving a 1.4-inch I.D. sampler with a 140 pound weight dropping 30 inches. Drilling and sampling operations were performed under the supervision of a field engineer, who also logged the borings and prepared samples for subsequent laboratory testing and reference. Soil materials were visually classified in the field according to the Unified Soil Classification System by observing the samples and the drill rig returns. A description of this classification system is presented at the front of Appendix A. 3.3 LABORATORY TESTING Laboratory tests were performed to provide a basis for foundation design and to develop grading recommendations. Dry densities and moisture contents were determined for the 2.5-inch diameter ameO Metropointe Engineers Job No.0-212-100600 Attention:Mr.Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex,Huntington Beach,California Page 10 in-situ samples; the results are presented on the Test Boring Logs in Appendix A. In addition to these index tests, laboratory soil testing program consisted of the following: • Grain size distribution determinations ; • Atterberg Limits determinations; • Water soluble sulphate determinations; • Minimum resistivity and pH determinations; • Moisture-density compaction curve determinations; • Direct shear tests; • Consolidation tests including consolidation rate determinations; • Flexible wall permeability tests; • Soil -water characteristic curve determinations; • Expansion Index tests; • (Resistance) R-value determinations; A brief description of each type of laboratory test and specific test results are presented in Appendix B. amee-Y Metropointe Engineers Job No.0-212-100600 Attention:Mr.Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach,California Page 11 4.0 SITE CHARACTERIZATION 4.1 SURFACE CONDITIONS The majority of the 45-acre project site is relatively flat. A large portion of the site has an artificial fill cap that has eradicated any natural topographic features. However, some slopes are found within the site due to the varying thickness of fill cover materials. Ground elevations in Area 3 along Golden West Street vary from about 46 feet to about 52 feet above m.s.l. In the Area 1, the grade generally descends from an elevation of about 70 feet near the south limit of the project site to about 50 feet along the north limit along Talbert Avenue. Descending slopes along the perimeter towards Golden West Street and the library parking lot on Talbert Avenue are typically about 5 to 10 feet in height, but locally extend up to approximately 15 feet in height. Pre-1950 air photographs included in the Environmental Impact Report prepared by Sapphos Environmental and dated February 26, 1999 depict a 35-foot deep erosional channel transecting the site from the northwest corner towards the center of the property where it continues to the south. Most of the site is an open area covered by grass and sparse shrubs. Overall drainage is poor and numerous occurrences of standing water may be found after rainfall in localized depressed areas. 4.2 SUBSURFACE CONDITIONS 4.2.1 Soil Fill Cap A large portion of the project site consists of a soil fill cap over landfill materials. As previously indicated, some of the material for the fill cap was imported from dredging of silty sand soil from Santa Ana River bottom. The source of the remaining fill cap materials is unknown. A portion of the project site in the mushroom farm area is covered by shallow fills consisting mostly of remediated materials excavated during expansion of the library parking lot. Determination of the fill cap depth in the area of the former Bruce Brothers Pit was difficult because the landfill materials were often intermixed with the overlying fill cap soil. The thickness of the fill cap over landfill areas varies significantly from about 3 feet to more than 20 feet. Typically,the fill cap thickness is greater than 5 feet. The fill cap soils are typically composed of loose to medium dense brown fine silty sand or sandy silt, or stiff low plasticity clay, with scattered gravels and rock fragments. Typically the relative compaction is about 80 percent. It is anticipated that these materials will be used for the construction of the alternative soil cover. ameO Metropointe Engineers Job No.0-212-100600 Attention: Mr.Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach,California Page 12 4.2.2 Landfill Materials Landfill materials were encountered in the majority of borings. The approximate limits of the landfill materials,based on interpretation of information obtained during previous investigations and during the course of this study,are shown on Plate II-Site Layout And Boring Locations Plan. Only a few borings penetrated through the landfill into the underlying terrace deposits. Based on these borings, it is estimated that the bottom of the landfill materials is up to 65 feet below the ground surface,which corresponds to an elevation of approximately 15 feet below m.s.l. Comparison with the pre-1950 topography indicates that significant excavation must have taken place before placement of the landfill. It is possible that the landfill locally extends even deeper. Additional study would be required to more thoroughly evaluate the depth of the landfill deposits. Household and municipal waste was encountered in borings drilled within the area of the former Golden West Street Disposal Station #10. The waste consisted of paper, glass, cardboard, newspaper, wood, wire, plastic, etc. Inert construction debris consisting of brick and masonry pieces and concrete and asphalt fragments were encountered within the footprint of the former Bruce Brothers Pit. However, a clear delineation between the municipal refuse and construction debris could not be determined. A rather extensive area containing miscellaneous construction debris and some organic materials exists between the two zones. This zone contains mostly concrete,asphalt and wood pieces within a silty sand soil matrix. Although no municipal refuse was encountered in borings within this area, hydrocarbon-contaminated soils were encountered similar to those previously found during the Central Library parking lot expansion. This contamination likely originated from disposal of rotary drilling muds. The contaminated intervals are generally localized, but thicknesses of up to 20 feet (AMEC,2000 boring B-2)were encountered. The drilling mud can be classified as very soft to soft dark grey silty clay. 4.2.3 Native Soils A review of the logs of the deep borings penetrating through the landfill materials in the northern portion of the site encountered medium dense to dense silty sand with smaller amounts of fines. Based on the review of geologic maps published by the California Division of Mines and Geology (CDMG),the site is underlain by red-brown Quaternary age non-marine terrace deposits. Native alluvial soils consisting mostly of very stiff clayey silt and sandy silt, and some medium dense silty sand were found near or at the surface in the area of the former mushroom farm. am le. Metropointe Engineers Job No.0-212-100600 Attention: Mr. Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach,California Page 13 4.2.4 Groundwater Groundwater was encountered only in boring B-1 (AMEC) at a depth of about 65 feet (elevation -18 feet). Based on the data reported by Kleinfelder in 1989 and 1990, groundwater elevations in the northwest portion of the project site were about -10 to -13 feet. This information is further corroborated by the 1989 SWAT investigation data,which concluded that the groundwater gradient is to the northwest-west, descending from elevations of about-6 feet to elevation -10 feet. Based on the existing data, it is AMEC's opinion that groundwater will not impact the proposed construction. Groundwater observations made during AMEC's 2000 field investigation are noted on the test boring logs included in Appendix A in the back of this report. Observations collected during the Kleinfelder's investigations are shown on the corresponding borehole logs in Appendix C. ameO Metropointe Engineers Job No.0-212-100600 Attention: Mr. Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach,California Page 14 5.0 ENGINEERING SEISMOLOGY 5.1 SEISMIC FRAMEWORK The project site is located in the general proximity of several active and potentially active faults.The Southern California region is known to be seismically active, and a significant database regarding geologic and seismic evidence is readily available. Earthquakes occurring within about 60 miles of the subject site are considered capable of generating ground shaking of engineering significance to the proposed construction. The engineering seismology evaluation study included a review of local and regional faulting, and historic earthquake data. The site is not located within a currently established Earthquake Fault Zone (formerly known as Alquist-Priolo Special Studies Zone). The Newport-Inglewood Fault is considered the active fault system governing the design of the project. Active faults are those which are known to have had surface displacement during the past 11,000 years. 5.2 SEISMIC DESIGN PARAMETERS Unless the Structural Engineer deems more seismic data is necessary(e.g.,site-specific response spectra) seismic design of the project may be performed using criteria presented in the 1997 Uniform Building Code, Volume 2, Chapter 16, Divisions IV and V, for the following seismic conditions. Design Fault. Newport=Inglewood Fault Seismic Source Type B Seismic Zone 4 Soil Profile Type SE Minimum Distance To Fault less than 2 km 5.3 LIQUEFACTION POTENTIAL ASSESSMENT The site is designated as an area with historic occurrence of liquefaction or local geological, geotechnical, and/or groundwater conditions suggestive of a potential for permanent ground displacement and shifting of the proposed structures (see the California Department of Conservation, Division of Mines and Geology Map of Seismic Hazards Zones for Seal Beach, East-Central 1/6 quadrangle, released on March 25, 1999). However, liquefaction has been documented primarily in loose saturated cohesionless soils with fines contents less than 30 percent. The on site soils have fines content typically greater than 30 percent, significant clay amedy Metropointe Engineers Job No.0-212-100600 Attention:Mr.Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex,Huntington Beach,California Page 15 content as documented by the Atterberg Limits and hydrometer test results, appreciable cohesion as documented by the direct shear test results, and can be typically described as medium dense. Even in saturated condition these soils would not be considered to possess a significant potential for liquefaction. The proposed development is intended not to allow for significant percolation of water into the subgrade soils. Consequently, it is AMEC's opinion That the potential for liquefaction at the site is considered minimal. ame& Metropointe Engineers Job No.0-212-100600 Attention:Mr. Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach,California Page 16 6.0 DESIGN RECOMMENDATIONS It is AMEC's opinion that the proposed development is feasible. However, the items described in the following paragraphs should be incorporated into the project specifications. It is anticipated that a functional site could be created without complete removal of existing fill and landfill materials, provided that periodic maintenance on as-needed basis is carried out. The proposed development has been laid out to reflect the specific design and environmental constraints associated with each of the four areas (Area 1, 2A, 213, and 3)within the development designated in Section 1.1. Consequently,specific recommendations are presented separately for each of the areas. 6.1 GENERAL DESIGN CONSIDERATIONS Geotechnical recommendations were developed for the subject site to meet the specific project needs. Current construction practices have been considered in the formulation of these recommendations. There are two major geotechnical design considerations for this project: 0 Reduction of infiltration of water into the underlying landfill, which will require construction of an adequate soil cover. • Mitigation of a significant total and differential settlement potential of the on-site landfill. Any excavation that would penetrate the existing soil cap should be avoided. This applies to grading activities associated with construction of any foundations, landfill gas collection system, and for overall site grading. As landfill materials cannot be relied on for consistent bearing support, a "cushion" of engineered soil fill is considered necessary to distribute surcharge loads over a greater area,thus reducing the potential for large angular distortions due to differntial settlement. Note: In this document the•words"soil cap"refers to the existing non-engineered soil fill overlying landfill materials; the words "soil cover" refer to the proposed engineered soil cover to be placed in a controlled manner. 6.1.1 Design Concepts Areal will consist of sporting fields, a tot lot and a concession / restroom facility located above inert construction debris and miscellaneous landfill materials. The sporting fields require a tun` and/or clay surface. The turf will be irrigated. An alternative soil final cover(AFC)is recommended to limit infiltration and percolation of precipitation and irrigation water into the underlying landfill amencly Metropointe Engineers Job No.0-212-100600 Attention: Mr.Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex,Huntington Beach,California Page 17 materials. No gas collection system is proposed for this area. The proposed structures including a retaining wall up to about 11 feet high, which is proposed near the tot lot, will require overexcavation and recompaction and geosynthetics soil reinforcement to provide an adequate subgrade support. Area 2A will consist of the proposed parking lot located above municipal refuse. The majority of the area will be covered with asphalt pavement and concrete flatwork. Planters are proposed on the parking lot islands. It is understood that the planters will be irrigated using a drip system designed to supply water only to the roots. No irrigated turf areas are proposed within Area 2A. An essentially impermeable asphalt cover placed over overexcavated and recompacted subgrade is proposed to significantly reduce infiltration into the subgrade soils. Area 213 is the location of the proposed roller hockey rinks, batting cage, and maintenance buildings. The open space will be a xeroscaped area with planters with drip irrigation systems. No irrigated turf areas are proposed within Area 26. The foundations of the proposed maintenance structures will require subgrade overexcavation and recompaction and geosynthetics soil reinforcement to provide an adequate subgrade support. Subgrade in the area of roller hockey rinks and the batting cage will require densification using deep dynamic compaction technique (DDC). An AFC installed above the DDC compacted soil is recommended to limit infiltration of precipitation water into the underlying municipal refuse. Water infiltration into the subgrade in Areas 2A and 213 will be monitored by an array of moisture sensors to provide both a feedback system for irrigation control and an alert system to prevent excessive accumulation of water within the AFC. A landfill gas collection system will be installed in Areas 2A and 2131, consisting of a system of vertical collection wells spaced approximately 200 feet apart and typically 60 to 70 feet deep. Area 3 in the southwest portion of the site will be utilized for baseball and soccer fields, a tot lot and a concession / restroom facility. The subsurface materials are relatively thin inert soil fill underlain by native terrace materials. Conventional grading, foundations, and ground cover are anticipated and recommended for the improvements in this area. Summary of geotechnical remediation measures is provided on Plate V in the back of this report. 6.1.2 Settlement Settlement considerations are anticipated to govern both the design and maintenance of all proposed structures and facilities. The settlement potential of various landfill materials has been extensively discussed in the literature as the need for closure and re-development.of former landfill sites is increasing. It is commonly accepted in the geotechnical community that the distribution of settlement potential throughout landfills generally is unpredictable and only a range of values can amet-Y Metropointe Engineers Job No.0-212-100600 Attention: Mr. Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach, California Page 18 be provided. Total landfill settlements on the order of 25 to 50 percent of the initial refuse thickness, depending on the amount of compaction energy applied at the time of placement, have been reported in the literature. Older landfills tend to compress more as the initial compaction energy was typically less than that used for more recent operations. Much of the settlement in landfills occurs at the time of placement, and the observed settlements after landfill closure are usually significantly smaller. AMEC's reconnaissance of the abandoned gun range facility, located immediately south of Area 1, indicated that structures on that site have experienced substantial differential settlement. The gun range is founded on the same type of municipal refuse landfill materials found under Area 2. The magnitude of to-date settlements in the gun range is not known, but differential displacement of several inches can be measured at vertical offsets of cracked pavements. Pervasive differential settlement over longer distances is evidenced by undulating paved surfaces. Given the similarity of subsurface conditions at the gun range facility to those at Areas 2A and 2B, the observations can be reasonably used for assessment of past subgrade performance in these areas. Landfill settlement results from self-compression of loosely placed deposits, decomposition of the refuse due to time or water action, and from compression due to external surcharges. Based on the observed performance at the gun range area, it may be asserted that the majority of the self- induced and decomposition settlement has already occurred. However, it should be understood that the project site will experience external surcharge due to site re-grading and associated fill placement or cuts, changes in drainage patterns and irrigation, and the proposed uses of the site. Consequently,significant potential for ongoing total and differential settlement still exists(probably up to several feet under typical operational conditions) and will require special mitigative and remedial design measures. Area 1, located above miscellaneous and inert construction debris landfill, may be less prone to settlement but significant subsidence potential still exists due to the uncontrolled placement of landfill materials, which may have created voids that could eventually lead to ground subsidence. A study related to the re-development of the existing gun range was prepared by CH2M Hill for NUVIS in October 1996. In general, AMEC concurs with the conclusions and recommendations provided in the CH2M Hill study,and considers them applicable to structures proposed forArea 2B. Specifically, these recommendations apply to the proposed batting cage, roller hockey rinks, and maintenance buildings. Generally, either piles and structural slab foundations for structures or significant ground improvement effort consisting of either dynamic compaction or pre-loading are deemed necessary. Geogrid or high strength geotextile subgrade stabilization is also recommended to improve distribution of surcharge loads by spreading loads laterally and engaging greater bearing area. In ameO Metropointe Engineers Job No.0-212-100600 Attention: Mr. Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach, California Page 19 the case of this project the function of the.geosynthetics stabilization is also to provide "bridging" over areas with greater subsidence, thus mitigating the effects of differential settlement. The deep dynamic compaction technique (DDC) within the areas of proposed structures is considered the best and most viable option for providing an adequate subgrade for the proposed development in Area 213. Light towers are considered sensitive to differential settlement due to the potential of development of significant tilt over the height of the tower. Foundations for towers located above landfill materials will require a special design measures including installation of grouting ports to facilitate re-leveling, geosynthetics reinforced subgrade, DDC, or pile foundations. Periodical maintenance of the parking lot and sporting fields will be required. Installation and monitoring. of settlement monuments is also recommended and required. by CCR Title 27 Environmental Protection. ameO Metropointe Engineers Job No.0-212-100600 Attention: Mr. Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach,California Page 20 6.2 AREA 1: NORTHEAST CORNER - RECREATIONAL AREA 6.2.1 Design Issues And Considerations (Area 1) The following issues,which are discussed in greater detail in the following paragraphs,may impact the proposed project and should be incorporated into the project specifications: • The area accommodates sporting fields with irrigated turf. • The presence of landfill materials will require placement of AFC to reduce infiltration into the landfill and generation of leachate. It is recommended that an AFC utilizing on-site materials be installed over the entire Area 1. • The area is underlain by landfill materials. Thus, the potential for significant differential settlement exists. Consequently, special design and maintenance measures will be required for the proposed concession/restroom building,tot lot,light towers foundations and sporting fields. 0 The existing soil cap consists of non-engineered fill with typical relative compaction of about 80 percent. Consequently, subgrade preparation consisting of overexcavation and recompaction will be required in the areas of proposed building and pavement/slab construction to provide adequate bearing support and to reduce differential settlement. • It is recommended that any excavation activities avoid penetration through the existing soil cap, in order to avoid exposure of the landfill materials to the atmosphere. • Drainage provisions to control surficial runoff should be implemented. • The on-site soils were found to possess a severe potential for corrosion of unprotected buried metals and a moderate potential for sulphate attack on buried concrete. • The on-site soils possess a moderate potential for expansion. 6.2.2 Alternative Soil Final Cover -Turf And Ball Fields Areas (Area 1) An alternative soil final cover(AFC)is recommended to limit infiltration of precipitation and irrigation water into the subgrade and percolation into the underlying construction debris landfill in the turf and ball fields areas of Area 1. In addition, the proposed sporting fields will have a subsurface drainage system which will assist in collecting infiltrated water and disposing it off-site. The design of the alternative soil cover has been verified by numerical modeling of water balance using the computer code WinUNSAT-H. The modeling considers the effects of irrigation along with the ame, Metropointe Engineers Job No.0-212-100600 Attention:Mr. Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach,California Page 21 effects of other climatic and vegetation factors. The approach,methodology,input parameters,and results of the numerical modeling are presented in Section 7.0 of this report. 6.2.2.1 Construction Recommendations For Alternative Soil Final Cover Initial site preparation should be carried out in accordance with general recommendations provided in Section 9.0 of this report. Specific recommendations for this component of the development are as follows: Within the AFC area the existing surface should be subcut to the bottom of the proposed cover. The bottom of the overexcavation should be observed by the Geotechnical Engineer for conformance with the intent of the recommendations and approved prior to any further processing or fill placement. The overexcavated surface should be moisture-conditioned to approximately 120 percent of the optimum moisture content and compacted to a minimum of 90 percent of the maximum dry density (ASTM D1557) to a depth of at least 12 inches. The monolithic soil laver should then be established by placing excavated soil in 6-to 8-inch (uncompacted)lifts free of any debris and/or deleterious materials,moisture conditioned to approximately 120 percent of optimum moisture content,and compacted to at least 90 percent of the maximum dry density.Specifications for the material of the monolithic soil layer are provided in Section 7.3. A sand drainage laver is recommended to be installed between the monolithic soil layer and the surface vegetative layer. The drainage layer will incorporate a subsurface drainage system and will provide a capillary break to the unsaturated flow. In order ensure adequate drainage capacity of the drainage layer, the sand should consist of well graded sand with less than 7 percent of particles passing the #200 sieve and have a sand equivalent of at least 40 as determined by California Test Method No. 217. The layer should be compacted at optimum moisture content to at least 85 percent of the maximum dry density (ASTM D1557). A drainage collection system consisting of prefabricated geosynthetics drainage elements, e.g., TerraDrain Strip Drains manufactured by Webtec, Inc. or a similar product, should be installed within the sand drainage layer. A vegetative layer will be placed on top of the monolithic compacted soil layer. The layer will provide adequate moisture storage for the roots. The vegetative layer supports growth of turf and landscaping, which must be selected to have low water requirements and shallow rooting. Plants should be watered using a non-pressurized, low-flow irrigation system incorporating feedback to shut itself off if leakage is detected. The vegetative layer should be compacted in 2 lifts at optimum moisture content to at least 85 percent of the maximum dry density(ASTM D1557). Surface grade should be contoured to transport all surface water to suitable storm water drains. The grading must prevent any ponding or pooling to prevent uncontrolled infiltration. As required by Article 2- §21090 b1 of CCR Title 27 Environmental Protection the cover should be graded at gradients of ameO Metropointe Engineers Job No.0-212-100600 Attention:Mr.Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex,Huntington Beach,California Page 22 no less than 3 percent and that the gradient be periodically re-established as settlement occurs. A periodic maintenance program should be implemented and repairs made promptly to limit the potential for water infiltration into the underlying materials. A typical cross-section through the proposed AFC, including the recommended thicknesses of individual layers, is shown in Figure 1. 6.2.3 Concession / Restroom Building (Area 1) 6.2.3.1 Site Preparation It is envisioned that the concession building construction will be conducted following the construction of AFC. Within the areas of the proposed concession/restroom building and paved areas (tot lot), the grade should be subcut to a minimum depth of 5 feet below the bottom of the proposed slab or foundation. The zone of removal should extend outside the perimeter of building areas by a minimum horizontal distance of 5 feet. The overexcavated surface should be moisture-conditioned to approximately 120 percent of optimum moisture content and compacted to a minimum of 90 percent of the maximum dry density (ASTM D1557) to a depth of at least 6 inches. Design subgrade elevation should then be re-established by placing excavated soil in 6-to 8-inch(uncompacted)lifts free of any debris and/or deleterious materials, moisture conditioned to approximately 120 percent of optimum moisture content, and compacted to at least 90 percent of the maximum dry density. In order to achieve a more uniform response of the subgrade to the surface loads, it is recommended that at least 3 layers of medium strength geogrids, e.g., Fortrac 55/30-20 with long term allowable design load of 2000 Ib/ft,or similar strength woven geotextile, e.g., Mirafi HP or XT, or alternative product, be placed at 1-foot vertical spacings within the re-compacted layer, starting 1 foot above the overexcavation bottom. The geosynthetics reinforcement should extent at least 5 feet outside the building perimeter. 6.2.3.2 Building Foundations- Post-Tension Slab-On-Grade Grading recommendations have been provided in order to mitigate the effects of compressible soils, however,as discussed in Section 6.1.2,even with these measures and proper site drainage, the potential for significant differential ground movement remains. A post-tensioned slab with a stiffening thickened edge is considered a feasible method of support for the proposed construction. Although post-tensioned floor slabs do not eliminate the potential for slab deflection or cracking, they provide for a strengthened, more rigid element, which generally tolerates differential movement with less cracking than a conventionally reinforced slab-on-grade. Post-tensioned slabs amedy Metropointe Engineers Job No.0-212-100600 Attention:Mr.Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach, California Page 23 should be designed in accordance with current Post Tensioning Institute design philosophy for post-tensioned slabs on compressible soils. The recommended geotechnical design parameters are as follows: Geotechnical Design Parameters for Post-tension Slab-on-grade for Buildings in Area 1 Estimated design differential ground movement 1 inch Variation distance 5 feet Allowable bearing capacity 1,500 psf -may be increased by 33%for seismic loading conditions Slab-subgrade friction coefficient 0.6 The bottom thickened edge around the perimeter of the structure should be extended at least 18 inches below the lowest adjacent grade. Unless superceded by the provisions in this section, the slab design should be carried out in accordance with general recommendations provided in Section 8.1 of this report. 6.2.4 Concrete Flatwork And Patio Slabs (Area 1) Conventionally reinforced concrete slabs-on-grade are proposed for concrete flatwork areas of the proposed tot lot and around the concession/bathroom building,and may be required for some other improvements and appurtenances within the development. Concrete slabs should be constructed following the construction of the AFC. It is recommended that the slabs be supported on at least 3 feet of engineered fill. It is anticipated that the AFC provides such a support,consequently,only a surficial treatment as described below, will be required: Within the areas of the proposed construction, the existing surface should be subcut to the bottom of the drainage layer, i.e., to the top of the AFC monolithic layer, or 1.5 feet below the bottom of the proposed slab, whichever is deeper. The zone of removal should extend outside the slab perimeter by a minimum horizontal distance of 3 feet.

The geosynthetics reinforcement should extent at least 3 feet outside the slab perimeter. The recommended geotechnical design parameters are as follows: Geotechnical Design Parameters for Concrete Flatwork and Patio Slabs in Area 1 Coefficient of subgrade reaction 150 ksi/inch Allowable bearing capacity 1,500 psf The design of the concrete flatwork and patio slabs should be carried out in accordance with general recommendations provided in Section 8.1 of this report. 6.2.5 Retaining Wall 6.2.5.1 Subgrade Preparation A retaining wall up to about 11 feet high and with a 2(H):1(V)toe slope is proposed near the tot lot in Area 1. It is understood that allowable bearing of 2,500 psf is required for an efficient foundation design. The following recommendations should be followed for design, construction and backfill of the retaining walls. The soils should be subcut to a minimum depth of 5 feet below existing grade or below the bottom of the proposed foundation,whichever is deeper. The zone of removal should extend outside the perimeter of proposed footing by a minimum horizontal distance of 5 feet. The overexcavated surface should be moisture-conditioned to approximately 120 percent of optimum moisture content and compacted to a minimum of 90 percent of the maximum dry density (ASTM D1557) to a depth of at least 6 inches.

If the allowable frictional resistance and allowable passive resistance are combined,the allowable passive resistance should be reduced by 50 percent. For purposes of design, the total allowable lateral resistance may be increased by one-third for short-term loading including dead plus live plus seismic or wind loading. 6.2.5.3 Wall Backfill And Subdrainage Backfill behind walls should consist of a select granular material within a 1(H):1(V)zone extending upward from the heel of the wall. Suitable select granular soil to be used as wall backfill should have a minimum sand equivalent of 20 as determined by California Test Method No. 217, and an Expansion Index of less than 20 as determined by UBC Standard 29-2. The typical on-site soils will not likely be suitable for wall backfill and import of adequate material or select on-site grading will be necessary. The allowable coefficient of friction between import soil backfill as specified above and concrete may be taken as 0.26 or 0.33, whichever is more conservative. Adequate subsurface drainage is essential to provide a free-drained backfill condition for the retaining wall. Subdrains should consist of crushed rock wrapped by non-woven geotextile or a continuous gravel drainage gallery constructed in hydraulic continuity with 4-inch diameter Schedule 40 PVC pipes with 0.25-inch perforations. The gravel drain section alternative should consist of a minimum of 2 cubic feet per lineal foot placed against the wail. The gravel should conform to Caltrans Class 2 permeable material or the equivalent. Due to the propensity of the on- site soils to migrate easily under hydraulic head, in no case should coarse rock be placed directly amec_"�,,oil V Metropointe Engineers Job No.0-212-100600 Attention:Mr.Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex,Huntington Beach,California Page 26 in contact with the native soils. Outlets should consist of a minimum 4-inch diameter pipe draining to a suitable discharge. To minimize surface water infiltration into granular backfill behind the walls, specifically outside of pavement or slab areas, it is recommended that at least 12 inches of relatively impervious material be placed as a cap over the granular backfill and sloped to prevent collecting of ponded water. 6.2.5.4 Lateral Earth Pressure Providing the backfill recommendations are followed, walls below grade may be designed for the applicable lateral earth pressure shown below. Design values are given for both active and at-rest pressures and assume complete drainage allowing no hydrostatic pore pressure build-up behind the wall. Design Condition Equivalent Fluid Pressure (psf) Active 44z + 0.360 At-Rest 65z + 0.53Q where: z ..... depth below the grade (ft) Q .... uniform surcharge load (psf)within a 1:1 plane drawn upward from the base of the wall Determination of which condition, active or at-rest, is appropriate for design will depend on the flexibility of the walls. Walls which are free to deflect 0.001 radians at the top should be designed for the active condition. Walls that are not capable of this movement should be assumed rigid and designed for the at-rest condition. The effect of any surcharge (dead or live load) located within should be added to the preceding lateral earth pressures as indicated in the table above. ameO Metropointe Engineers Job No.0-212-100600 Attention:Mr.Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach, California Page 27 6.3 AREA 2A: NORTHWEST CORNER - PARKING LOT 6.3.1 Design Issues And Considerations (Area 2A) The following issues,which are discussed in greater detail in the following paragraphs,may impact the proposed project and should be incorporated into the project specifications: • The municipal refuse landfill materials have a potential to generate methane. Consequently, a landfill gas collection system will be required. • In order to reduce the potential for water infiltration into the landfill and the production of methane, placement of an essentially impermeable asphalt pavement cover is recommended. No numerical modeling is deemed necessary,since the asphaltic pavement in combination with a periodic maintenance and monitoring program is considered to provide adequate protection against infiltration. • Planters located within this area will have a drip irrigation system which will supply moisture to the plants on as-needed basis. No irrigated turf areas are proposed. • The area is underlain by landfill materials, thus the potential for significant differential settlement exists. Consequently, special design and maintenance measures will be required for the parking lot and associated facilities. 0 The existing soil cap consists of non-engineered fill with typical relative compaction of about 80 percent. Consequently, subgrade preparation consisting of overexcavation and recompaction will be required in the areas of proposed pavement or flatwork construction to provide adequate bearing support and reduce differential settlement. • It is recommended that any excavation activities avoid penetration through the existing soil cap, in order to avoid exposure of landfill materials to the atmosphere. • Drainage provisions to control surficial runoff should be implemented. • The on-site soils were found to possess a severe potential for corrosion of unprotected buried metals and a moderate potential for sulphate attack on buried concrete. 0 The on-site soils possess a moderate potential for expansion.

Specific recommendations for this component of the development are as follows: Within the area of the proposed parking lot and associated planters and sidewalk areas, the existing surface should be subcut to a minimum depth of 3 feet below existing grade or below the bottom of the proposed aggregate base layer, whichever is deeper. The bottom of the overexcavation should be observed by the Geotechnical Engineer for conformance with the intent of the recommendations and approved prior to any further processing or fill placement. The overexcavated surface should be moisture-conditioned to approximately 120 percent of optimum moisture content and compacted to a minimum of 90 percent of the maximum dry density (ASTM D1557) to a depth of at least 12 inches. Design subgrade elevation should then be re-established by placing excavated soil in 6-to 8-inch(uncompacted)lifts free of any debris and/or deleterious materials, moisture conditioned to approximately 120 percent of optimum moisture content, and compacted to at least 90 percent of the maximum dry density. Compaction of the uppermost 12 inches of the subgrade, immediately below the aggregate base layer, should be increased to a minimum of 95 percent of ASTM D1557. The aggregate base layer should be separated from the subgrade soils by a higher strength woven geotextile, e.g., Mirafi® HP 570 or equivalent,with ultimate tensile strength of at least 4800 psf. The geotextile is intended to provide soil separation, subgrade stabilization, and reinforcement functions. The pavement section for the parking lot should be placed on subgrade placed in accordance with the above recommendations and should consist of components as indicated in the following table: Parking Lot Pavement Section Recommendations Component Thickness Note Seal Coat n/a • provides for decreased permeability • will need to be periodically maintained Class D2 2.4 inches • provides tighter matrix to accept the seal coat Asphaltic %_"gradation • provides finer texture for the wearing course Concrete (AC) (2%void mix) Class C2 3 inches • provides strength 3/4"gradation Aggregate Base (AB) 8 inches amec-Y Metropointe Engineers Job No.0-212-100600 Attention:Mr.Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach, California Page 29 Asphaltic concrete (AC)and aggregate base (AB)should conform to the Specifications for Public Works Construction Sections 203-6 and 200-2, respectively. It should be understood that the design of the proposed flexible pavement section is governed by the potential for differential settlement of subsurface materials rather than by the loading from the anticipated traffic. However,this proposed flexible pavement section has been verified in general accordance with the Orange County Highway Design Manual method of flexible pavement design using a 20-year design life, and was found to exceed requirements for an assumed R-value of 6 and Traffic Index of 5. Paved areas should be properly sloped at a minimum of 3 percent and surface drainage facilities established to minimize water infiltration at the limits of pavement and into the pavement subgrade. The subgrade below the aggregate base should be sloped towards collection drainage pipes connected to a storm drain system. The pavements and parking areas will undergo long term settlements due to the presence of deep landfill materials. A periodic maintenance program must be implemented and repairs made promptly to limit potential for water infiltration into the underlying materials. . Landscaping should be selected to have low water requirements and shallow rooting. The plants should be watered using a non-pressurized, low-flow irrigation system incorporating feedback to shut itself off if leakage is detected. The parking lot pavement should be designed with positive drainage to remove precipitation runoff, conveying it off-site. a mem Metropointe Engineers Job No.0-212-100600 Attention:Mr.Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach,California Page 30 6.4 AREA 213: CENTRAL CORNER— ROLLER HOCKEY COURTS 6.4.1 Design Issues And Considerations (Area 26) The following issues,which are discussed in greater detail in the following paragraphs, may impact the proposed project and should be incorporated into the project specifications: • The surface area will be covered by 4 concrete roller hockey rinks (approximately 90 feet x 180 feet)and a batting cage(approximately 20,000 square feet). The remaining area will be xeroscaped and exposed only to precipitation water. • . Planters located within this area will have a drip irrigation system which will supply moisture to the plants on as-needed basis. No irrigated turf areas are proposed. • The presence of landfill materials will require an installation of AFC to reduce infiltration into the landfill and generation of leachate. It is recommended that an AFC utilizing on-site materials be installed. The AFC should be placed over the entire Area 213, i.e., including under the proposed structures. • The area is underlain by non-engineered landfill materials. Thus, the potential for significant differential settlement exists. Also, the existing soil cap consists of non- engineered fill with typical relative compaction of about 80 percent. Consequently, subgrade preparation consisting of deep dynamic compaction (DDC) is recommended in the areas of proposed building and pavement/slab construction to provide adequate bearing support and to reduce post-construction differential settlement. 0 It is recommended that any excavation activities avoid penetration through the existing soil cap, in order to avoid exposure of the landfill materials to the atmosphere. • Drainage provisions to control surficial runoff should be implemented. • The on-site soils were found to possess a severe potential for corrosion of unprotected buried metals and a moderate potential for sulphate attack on buried concrete. • The on-site soils possess a moderate potential for expansion. 6.4.2 Deep Dynamic Compaction (Area 213) Deep dynamic compaction (DDC) improvement of subsurface materials is recommended in the areas of proposed roller hockey rinks, batting cage, and service buildings. The design of foundations for these structures presents a significant geotechnical challenge. These structures, in particular the roller hockey rinks,are not considered to be tolerant to cracking. This requirement, in combination with the challenging foundation materials (non-engineered soil cap and municipal ame%. - Metropointe Engineers Job No.0-212-100600 Attention:Mr.Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach,Califomia Page 31 refuse landfill), requires a robust foundation design. It is anticipated that the cost of construction of the roller hockey rinks will be reflective of these difficult foundation conditions. Deep dynamic compaction technique is recommended to increase the stiffness of the subgrade materials and reduce the potential for settlement and for development of differential settlement. DDC is a process whereby a tamper weighing up to 30 tons is raised above the ground and allowed to fall from heights up to 100 feet. The energy of the fall is released upon impact on the ground as the compaction energy, which causes increase in soil density and stiffness. The depth of compaction improvement depends upon the mass of the tamper, the height of the fall, and the soil material type. 6.4.2.1 Site Preparation For DDC Initial site preparation should be carried out in accordance with general recommendations provided in Section 9.0 of this report. In addition, the entire DDC area should be overexcavated to a minimum depth of 1 foot above the base of the proposed AFC. The area of DDC improvement should extend outside the perimeter of the proposed structures, i.e., roller hockey rinks, batting cage, maintenance building, and landfill gas collection system control building, by a horizontal distance of 10 feet. 6.4.2.2 General DDC Specifications The recommended minimum depth of treatment is 20 feet below the prepared grade. The DDC treatment program should yield an increase of the SPT blowcount within the treatment area above 20 blows per 12 inches of penetration. As a general guideline, it is anticipated that based on the subsurface conditions encountered during the field exploration a DDC program consisting of 7 drops of a 20-ton weight from about 50 feet plus an ironing pass on a 12 feet by 12 feet square grid pattern would be sufficient to improve the subsurface materials. It is recommended that a test section be carried out prior to construction in order to verify the effectiveness of the DDC program and, if required, modify it to suit the specific site conditions. Either a performance or method specification for the DDC program would be acceptable for this project. It is our opinion that the performance specification with performance control supervised by the consultant would be the most effective type of specification. After the completion of the DCC program, any loose soil, trash or other deleterious material encountered within the DDC treated zones should be removed and recompacted and a subgrade should be established matching the overexcavation subgrade of the adjacent areas prepared to receive the AFC. The AFC should be than installed as indicated in Section 6.4.3 below. ameO Metropointe Engineers Job No.0-212-100600 Attention: Mr. Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex,Huntington Beach,California Page 32 6.4.3 Alternative Soil Final Cover -Xeroscape Areas (Area 213) Alternative soil final cover(AFC) is recommended to limit infiltration of precipitation water into the subgrade and percolation into the underlying municipal refuse landfill. No irrigated turf areas are proposed in Area 2B. As the construction schedule of the proposed structures is unknown and uncertain, the AFC within the entire Area 213 should be continuous and should be placed as a part of single grading effort, i.e., no distinction should be made between the DDC improved and the adjacent areas. The design of the AFC has been verified for compliance with the requirements of California Code Of Regulations, Title 27 - Environmental Protection using the computer code WinUNSAT-H. The approach, methodology, input parameters, and results of the numerical modeling are presented in Section 7.0 of this report. 6.4.3.1 Construction Recommendations For Alternative Soil Final Cover Initial site preparation should be carried out in accordance with general recommendations provided in Section 9.0 of this report. The activities described in the following paragraphs should be carried out following the completion of the deep dynamic compaction (DDC) operations (Section 6.4.2). Following the initial preparations, the entire Area 213 should. be subcut to the bottom of the proposed cover. The bottom of the overexcavation should be observed by the Geotechnical Engineer for conformance with the intent of the recommendations and approved prior to any further processing or fill placement. The overexcavated surface should be moisture-conditioned to approximately 120 percent of the optimum moisture content and compacted to a minimum of 90 percent of the maximum dry density (ASTM D1557) to a depth of at least 12 inches. The monolithic soil laver should then be established by placing excavated soil in 6- to 8-inch (uncompacted) lifts free of any debris and/or deleterious materials, moisture conditioned to approximately 120 percent of optimum moisture content, and compacted to at least 90 percent of the maximum dry density. The top of the monolithic layer should be graded to provide a positive drainage for any water that migrates through the upper layers. The water should be collected in and discharged to a suitable location. An erosion-resistant layer will be placed on top of the monolithic compacted soil layer. The erosion-resistant layer should be compacted in 2 lifts at optimum moisture content to at least 85 percent of the maximum dry density (ASTM D1557). Surface grade should be contoured to transport all surface water to suitable storm water drains. The grading must prevent any ponding or pooling to prevent uncontrolled infiltration. As required by Article 2 - §21090 b1 of CCR Title 27 Environmental Protection the cover should be graded at gradients of no less than 3 percent and that the gradient be periodically re-established as settlement occurs. A periodic maintenance program should be implemented and repairs made promptly to limit the potential for water infiltration into the underlying materials. A typical cross-section through the proposed AFC, including the thicknesses of individual layers, is shown in Figure 3. amen&- Metropointe Engineers Job No.0-212-100600 Attention: Mr. Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach,California Page 33 6.4.4 Roller Hockey Rinks And Batting Cage (Area 2B) 6.4.4.1 Site Preparation Roller hockey rinks, batting cage, and the service buildings will be located in areas improved by DDC and overlain by AFC. Recommendations provided in Sections 6.4.2 and 6.4.3 apply. However, it is anticipated that these structures will be constructed at some time later after completion of grading operations. Consequently,in the areas of proposed construction the erosion- resistant layer and should be removed and replaced with engineered fill and geosynthetics reinforcement as described in the following paragraphs Within the areas of the proposed construction,the existing surface should be subcut to the bottom of the erosion-resistant layer, i.e., to the top of the AFC monolithic layer, or 1.5 feet below the bottom of the proposed slab or foundation, whichever is deeper. The zone of removal should extend outside the perimeter of proposed structures by a minimum horizontal distance of 5 feet. The overexcavated surface should be moisture-conditioned to approximately 120 percent of optimum moisture content and compacted to a minimum of 90 percent of the maximum dry density (ASTM D1557) to a depth of at least 6 inches. Design subgrade elevation should then be re-established by placing excavated soil in 6-.to 8-inch(uncompacted)lifts free of any debris and/or deleterious materials, moisture conditioned to approximately 120 percent of optimum moisture content, and compacted to at least 90 percent of the maximum dry density. In order to achieve a more uniform response of the subgrade to the surface loads, it is recommended that at least 1 layer of medium strength geogrid, e.g., Fortrac 55/30-20 with long term allowable design load of 2000 Ib/ft,or similar strength woven geotextile,e.g., Mirafi HP or XT, or alternative product, be placed within 1 foot of the bottom of the foundation bottom. The geosynthetics reinforcement should extent at least 5 feet outside the perimeter of the structure's footprint. 6.4.4.2 Foundation Recommendations Grading and compaction recommendations have been provided in order to mitigate the effects of compressible soils and non-uniform subsidence potential. However,as discussed in Section 6.1.2, even with these measures and proper site drainage,the potential for significant differential ground movement remains. A properly designed post-tensioned, conventionally reinforced, or soecialty reinforced slab are considered feasible options of support for the proposed construction.. Unless superceded by the provisions in this section, the design should be carried out in accordance with general recommendations provided in Section 8.1 of this report. Considering the large span of the proposed slabs, a heavily reinforced conventional slab system foundation with thickened edge and internal stiffening ribs is anticipated to be the most preferred option. It is understood that the roller hockey ring and batting cage construction may be delayed. Consequently, the on-site survey monuments and observations data on performance of the AFC ameO Metropointe Engineers Job No.0-212-100600 Attention:Mr.Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex,Huntington Beach,California Page 34 and the entire project area may be available at that time. It is therefore recommended that the design parameters provided in the table below, be reviewed with this office to incorporate all available information. Geotechnical Design Parameters for Roller Hockey Rink and Batting Cage Conventional Floor Slab Coefficient of subgrade reaction 150 ksi/inch Allowable bearing capacity 1,500 psf Effective plasticity index 13 percent Alternatively, specialty reinforced concrete slab system, e.g., fibre reinforced concrete, may be considered to reduce propagation of any cracking. Another alternative is a post-tensioned floor slab system foundation. Although post-tensioned floor slabs do not eliminate potential for slab deflection or cracking, they provide for a strengthened, more rigid element, which generally tolerates differential movement with less cracking than a conventionally reinforced slab-on-grade. Post-tensioned slabs should be designed in accordance with current Post Tensioning Institute design philosophy for post-tensioned slabs on compressible soils. The recommended geotechnical design parameters are as follows: Geotechnical Design Parameters for Roller Hockey Rink and Batting Cage Post-Tensioned Floor Slab Estimated design differential ground movement 1 inch Variation distance 10 feet Allowable bearing capacity 1,500 psf -may be increased by 33%for seismic loading conditions Slab-subgrade friction coefficient 0.6 The bottom thickened edge around the perimeter of the structure should be extended at least 18 inches below the lowest adjacent grade.

However, it is anticipated that post-tensioned floor slab foundation system is the preferred option to provide an adequate and economical support for the proposed structures. 6.4.6 Concrete Flatwork And Patio Slabs (Area 2B) Concrete slabs-on-grade are proposed for the paved areas around the roller hockey rinks, batting cage and other structures in Area 213, and may be required for some other improvements and appurtenances within the development. Concrete slabs should be constructed following the construction of the AFC. It is recommended that the slabs be supported on at least 3 feet of engineered fill. It is anticipated that the AFC provides such a support,consequently,only a surficial treatment as described below, will be required: Within the areas of the proposed construction, the existing surface should be subcut to the bottom of the erosion-resistant layer, i.e., to the top of the AFC monolithic layer, or 1.5 feet below the bottom of the proposed slab, whichever is deeper. The zone of removal should extend outside the slab perimeter by a minimum.horizontal distance of 3 feet. The overexcavated surface should be moisture-conditioned to approximately 120 percent of optimum moisture content and compacted to a minimum of 90 percent of the maximum dry density(ASTM D1557)to a depth of at least 6 inches.

The subsurface materials consist of relatively thin inert soil fill underlain by native terrace materials. Conventional grading, foundation, and ground cover are proposed for this area. The following issues,which are discussed in greater detail in the following paragraphs, may impact the proposed project and should be incorporated into the project specifications: • The on-site soils were found to possess a severe potential for corrosion of unprotected buried metals and a moderate potential for sulphate attack on buried concrete. • The on-site soils possess a moderate potential for expansion. 6.5.2 Concession Building And Tot Lot (Area 3) 6.5.2.1 Site Preparation. Initial site preparation should be carried out in accordance with general recommendations provided in Section 9.0 of this report. Specific recommendations for this component of the development are as follows: Within the area of the proposed concession / restroom building and paved areas (tot lot) the existing surface for should be subcut to a minimum depth of 3 feet below existing grade, below the bottom of any non-engineered fill, or below the bottom of the proposed slab or foundation, whichever is deeper. The zone of removal should extend outside the perimeter of building areas a horizontal distance of 3 feet. The bottom of the overexcavated area should be observed by the Geotechnical Engineer for conformance with the intent of the recommendations and approved prior to any further processing or fill placement. The overexcavated surface should be moisture-conditioned to approximately 120 percent of optimum moisture content and compacted to a minimum of 90 percent of the maximum dry density (ASTM D1557) for a depth of at least 6 inches. Design subgrade elevation should then be re-established by placing excavated soil in 6-to 8-inch(uncompacted)lifts free of any debris and/or deleterious materials, moisture conditioned to approximately 120 percent of optimum moisture content, and compacted to at least 90 percent of the maximum dry density. 6.5.2.2 Building Foundations Conventional spread or continuous footings should be founded on subgrade soils which are prepared as recommended in the Section 6.5.2.1 of this report and should be embedded at least ameO Metropointe Engineers Job No.0-212-100600 Attention:Mr.Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach,California Page 38 21 inches below the lowest adjacent grade. It is recommended that continuous footings or grade beams be minimally reinforced with one#4 bar at both the top and bottom and have a minimum width of 12 inches. The recommended geotechnical design parameters are as follows: Geotechnical Design Parameters for for Spread and Continuous Footing Foundations for Buildings in Area 3 Allowable average bearing capacity 2,500 psf -may be increased by 33%for seismic loading conditions Allowable coefficient of friction 0.35 Allowable lateral passive resistance (EFP) 250 psf+ 180 psf/foot of depth of embedment Lateral loads may be resisted by friction between the supporting soils and the bottom of footings and/or by lateral passive resistance acting against the sides of footings. If the allowable frictional resistance and allowable passive resistance are combined,the allowable passive resistance should be reduced by 50 percent. For purposes of design, the total allowable lateral resistance may be increased by one-third for short-term loading including dead plus live plus seismic or wind loading. 6.5.2.3 Floor Slabs, Concrete Flatwork, And Patio Slabs Concrete slabs-on-grade are proposed for the paved areas of the proposed tot lot and around the concession / restroom building and may be required for some other improvements and appurtenances within the development. Concrete slabs should be placed on subgrade prepared in accordance with Section 6.5.2.1 of this report. Unless superceded by the provisions in this section, the design should be carried out in accordance with general recommendations provided in Section 8.1 of this report. Due to the proximity of the abandoned oil well,a vapor barrier,such as a polyethylene membrane, is required beneath the building slabs. The buildinq_floor slab should be tied to exterior footings by#4 bars spaced to coincide with the slab reinforcement. To minimize differential movement, it is recommended that reinforcement be extended through control joints. In addition, all slabs-on-grade should have the minimum reinforcement and exterior and interior beams as outlined by the UBC Code Section 1815. For exterior concrete flatwork, it is recommended that narrow strip concrete slabs, such as walkways, be provided with minimum reinforcement of#4 bars placed longitudinally at 24 inches on center.

Specific recommendations for this component of the development are as follows: Within area of the proposed sporting fields the existing surface should be subcut to a minimum depth of 1.5 foot below the existing grade or below the proposed grade, whichever is deeper. Special attention should be paid to the area in the northeast corner adjacent to Area 213, where some shallow miscellaneous refuse fills were encountered (Kleinfelder, 1990, B-27) and deeper overexcavation may be required. The bottom of the overexcavation should be observed by the Geotechnical Engineer for conformance with the intent of these recommendations and approved prior to any further processing or fill placement. The overexcavated surface should be moisture-conditioned to approximately 120 percent of optimum moisture content and compacted to a minimum of 90 percent of the maximum dry density (ASTM D1557) for a depth of at least 6 inches. Design subgrade elevation should then be re- established by placing excavated soil in 6-to 8-inch (uncompacted) lifts free of any debris and/or deleterious materials, moisture conditioned to approximately 120 percent of optimum moisture content, and compacted to at least 90 percent of the maximum dry density. A drainage system consisting of either a sand layer and the overlying vegetative layer or a prefabricated geosynthetics drainage system, e.g., TerraDrain Strip Drains manufactured by Webtec, Inc. or a similar product, should be installed. The turf design should be•carried out by a specialist and should be based on the Agricultural Suitability Report included in Appendix F. 6.5.4 Trailer Park Sound Wall (Area 3) Foundations for the sound wall may be designed according to the recommendations and using design parameters provided in Section 6.5.2.1 and 6.5.2.2 of this report. ameO Metropointe Engineers Job No. 0-212-100600 Attention: Mr. Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex,Huntington Beach, Califomia Page 40 6.6 LIGHT TOWER AND LIGHT POLE FOUNDATIONS 6.6.1 Light Tower Foundations Light towers are proposed to provide illumination of the sporting fields. The towers are typically about 70 to 80 feet tall and generally require relatively large spread footing foundations to provide adequate resistance to overturning moments due to wind loading. Footprint dimensions between 10 x 10 feet and 15 x 15 feet are anticipated. The typical thickness of the concrete footing block is about 4 feet and the foundation depth is about 6 feet. In order to provide adequate bearing capacity, competent bearing materials have to extend below at least 1.25 times the width of the footing below the bottom of the footing, i.e., to a depth of 17 feet (10 x 1.25 + 6 feet) and 25 feet (15 x 1.25 + 6 feet)for a 10x10-foot and a 15x15-foot footing with a footing base at a depth of 6 feet, respectively. Area 1: All light towers in Area 1, with the likely exception of locations A13, A14, and B14 which may be designed using conventional approaches, are located above landfill materials and will require a special design attention. Light tower location designations were taken from 50 percent submittal plans prepared by Metropointe Engineers. Area 3: Light towers in Area 3 are generally not subject to limitations due to the presence of the landfill materials and may be designed using conventional approaches. Only light tower locations designated as 137 and S3 may require special design attention. 6.6.1.1 Foundation Design Outside Landfill Areas Conventional foundation design may be used for light towers outside the landfill areas,i.e.,in Area 3 and possibly at locations A13, A14, and B14 in Area 1. Within the area of the proposed light towers the existing foundation subgrade should be subcut into competent native materials to a minimum depth of 3 feet below existing grade, below the bottom of any non-engineered fill, or below he bottom of the proposed foundation or foundation, whichever is deeper. The zone of removal should extend outside the perimeter of the footing by a horizontal distance of 3 feet. The bottom of the overexcavated area should be observed by the Geotechnical Engineer for conformance with the intent of the recommendations and approved prior to any further processing or fill placement. The overexcavated surface should be moisture-conditioned to approximately 120 percent of optimum moisture content and compacted to a minimum of 90 percent of the maximum dry density (ASTM D1557)for a depth of at least 6 inches. Design subgrade elevation should then be re-established by placing excavated soil in 6-to 8-inch (uncompacted) lifts free of any debris and/or deleterious materials, moisture conditioned to approximately 120 percent of optimum moisture content, and compacted to at least 90 percent of the maximum dry density. ame Metropointe Engineers Job No.0-212-100600 Attention:Mr.Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex,Huntington Beach,California Page 41 The recommended geotechnical design parameters are as follows: C%s Geotechnical Design Parameters for for Footing Foundations for Light Towers in Area 3 Allowable average bearing capacity 2,500 psf -may be increased by 33%for seismic loading conditions, or -may be increased by 33%for maximum toe pressure evaluation Allowable coefficient of friction 0.35 Allowable lateral passive resistance (EFP) 160 psf/foot of depth of embedment Lateral loads may be resisted by friction between the supporting soils and the bottom of footings and/or by lateral passive resistance acting against the sides of footings. If the allowable frictional resistance and allowable passive resistance are combined,the allowable passive resistance should be reduced by 50 percent. For purposes of design, the total allowable lateral resistance may be increased by one-third for short-term loading including dead plus live plus seismic or wind loading. 6.6.1.2 Foundation Design Within Landfill Areas Combination of several design concepts listed below is considered the most feasible approach for light tower foundations located within landfill areas: • A modified footing design with grouting ports in conjunction with a rigorous monitoring program. The placement of the grouting ports along the footing perimeter would allow re-leveling of the foundation; • Ground improvement in the foundations locations by DDC; • Geosynthetics reinforcement of the foundation subgrade; It is recommended is to design all light tower foundations in Area 1 (with possible exception of locations A13, A14, and B14) with grouting ports consisting of at least eight 4-inch diameter galvanized steel pipes installed uniformly along the footing perimeter. Injection pressure grouting would be used if angular distortion of the footing.causing the tilt of the light pole would exceed 1 in 50 (2.5 inches in 10 feet) in any direction. DDC Improved Subgrade: Where possible, i.e., locations along the southern limit of Area 1 (e.g., A9, A10, Al2, B9, 1312, C1, S8), the subgrade materials should be improved using DDC. It is anticipated that on-site experience from DDC operations in Area 213 could assist in development of a suitable DDC program for light tower locations. Consequently, a modified (to limit vibrations and undesirable effects on nearby structures)DDC program could be considered at locations along ameO Metropointe Engineers Job No.0-212-100600 Attention:Mr. Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach,California Page 42 Gothard Street and Talbert Avenue, e.g., at locations Al 5, Al 6, 1310, 1313, 615, C2, S4, S5, S7). The DDC improvement should extent at least 12 feet outside the perimeter of the proposed footings. The DDC should be carried out prior to AFC construction and in conjunction with DDC operations in Area 213 and in general accordance with recommendations provided in Section 6.4.2 of this report. The excavation for light tower foundations within DDC improved areas should proceed following the installation of AFC. Within the areas of the proposed construction, the existing surface should be subcut to subcut into to a minimum depth of 2 feet below the base of the proposed foundation footing. The zone of removal should extend outside the perimeter of the proposed footing by a minimum horizontal distance of 3 feet. The overexcavated surface should be moisture-conditioned to approximately 120 percent of optimum moisture content and compacted to a minimum of 90 percent of the maximum dry density (ASTM D1557) to a depth of at least 6 inches. Design subgrade elevation should then be re-established by placing excavated soil in 6- to 8-inch (uncompacted) lifts free of any debris and/or deleterious materials, moisture conditioned to approximately 120 percent of optimum moisture content, and compacted to at least 90 percent of the maximum dry density. The recommended geotechnical design parameters are as follows: Geotechnical Design Parameters for for Footing Foundations for Light Towers in Area 1 on DDC-improved Subgrade Allowable average bearing capacity 2,000 psf -may be increased by 33%for seismic loading conditions,or -may be increased by 33%for maximum toe pressure evaluation Allowable coefficient of friction 0.35 Allowable lateral passive resistance (EFP) 200 psf/foot of depth of embedment In areas where DDC is not acceptable, a location-specific design reflecting the subsurface conditions at each foundation footing foundation should be developed. It should be understood, that insufficient information is available for some light tower locations and a supplemental field investigation program will be required. The design approach can be differentiated according to the thickness of soil cap above landfill materials. It is recommended that in locations, where the soil cover thickness below the base of the light tower footing is at least 8 feet,the foundation subgrade be prepared by overexcavation and recompaction and geogrid /geotextile soil reinforcement. More than 8 feet of soil cap below the base of the footing: In areas where the thickness of the soil cap below the proposed footing base is more than 8 feet, the soil cap materials should be subcut into to a minimum depth of 5 feet below the bottom of the proposed foundation. The zone of removal should extend outside the perimeter of the footing by a horizontal distance of 5 feet. The bottom of the overexcavated area should be observed by the Geotechnical Engineer for ameO Metropointe Engineers Job No.0-212-100600 Attention:Mr. Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach,California Page 43 conformance with the intent of the recommendations and approved prior to any further processing or fill placement. The overexcavated surface should be moisture-conditioned to approximately 120 percent of optimum moisture content and compacted to a minimum of 90 percent of the maximum dry density (ASTM D1557)for a depth of at least 6 inches. Design subgrade elevation should then be re-established by placing excavated soil in 6-to 8-inch (uncompacted) lifts free of any debris and/or deleterious materials, moisture conditioned to approximately 120 percent of optimum moisture content, and compacted to at least 90 percent of the maximum dry density. In order to achieve a more uniform response of the subgrade to the surface loads, it is recommended that at least 3 layers of medium strength geogrid, e.g., Fortrac 55/30-20 with long term allowable design load of 2000 Ib/ft,or similar strength woven geotextile, e.g., Mirafi HP or XT, or alternative product, be placed within 1 foot of the bottom of the foundation bottom,starting 1 foot below the base of the footing. The geosynthetics reinforcement should extent at least 5 feet outside the perimeter of the structure's footprint. The recommended geotechnical design parameters are as follows: Geotechnical Design Parameters for for Footing Foundations for Light Towers in Area 1 at Locations with at Least 8 Feet of Soil Subgrade below the Footing Base Allowable average bearing capacity 1,500 psf -may be increased by 33%for seismic loading conditions,or -may be increased by 33%for maximum toe pressure evaluation Allowable coefficient of friction 0.35 Allowable lateral passive resistance (EFP) 160 psf/foot of depth of embedment Lateral loads may be resisted by friction between the supporting soils and the bottom of footings and/or by lateral passive resistance acting against the sides of footings. If the allowable frictional resistance and allowable passive resistance are combined,the allowable passive resistance should be reduced by 50 percent. For purposes of design, the total allowable lateral resistance may be increased by one-third for short-term loading including dead plus live plus seismic or wind loading. Less than 8 feet of soil cap below the base of the footing: For light tower foundations locations with less than 8 feet of soil cap materials below the base of the footing, e.g., A15, B16, a special subgrade preparation program will have to be implemented. It is anticipated that compaction grouting of the soil cover and construction debris materials or pile foundations be acceptable. ameO Metropointe Engineers Job No.0-212-100600 Attention:Mr.Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach,California Page 44 6.6.2 Light Pole Foundations Lights are proposed to provide illumination of the parking lot, sidewalks, walkways, and adjacent areas. The poles are typically about 20 to 30 feet tall and generally require short "stubby" pre-bored cast-in-place concrete pile foundations, 5 or 6 feet deep and 2 to 2.5 feet in diameter. Pre-bored cast-in-place piles are considered feasible for Area 3 (no landfill) and in landfill areas with soil depth of at least 9 feet and no geosynthetics reinforcement, i.e., outside Area 2A. Review of pertinent subsurface data indicates that the soil thickness in Area 2 and 3 is typically greater than 10 feet below design grade, however extensive areas with shallower thickness exist along Golden West Street and near the Area 2A and 213 border. Consequently, it is recommended that the pre-bored cast-in-place pile foundations system be adopted only for Area 3. In Area 2A enlarged footings founded above the geosynthetics reinforcement layer are recommended. In Areas 1 and 26: Given the uncertainties regarding the thickness of the cover above landfill materials, it is recommended that all light poles in landfill areas of Areas 1 and 213 be installed to a minimum depth of 5 feet below grade using driven piles. The recommended geotechnical design parameters are as follows: Geotechnical Design Parameters for for Driven Pile Foundations for Light Poles in Areas 1 and 213 Allowable average bearing capacity 1,500 psf -may be increased by 33%for transient loading conditions Allowable lateral passive resistance (EFP) 200 psf/foot of depth of embedment In Area 2A: Area 2A consists of a paved parking lot placed on top of recompacted subgrade separated from the underlying materials by a geosynthetics layer. Consequently, it is recommended to place the light poles on enlarged footings founded above the geosynthetics layer. It is recommended that all light poles in Areas 2A be installed to a depth no closer than 6 inches above the geosynthetics layer and no shallower than 3 feet below the final grade. The recommended geotechnical design parameters are as follows: Geotechnical Design Parameters for for Enlarged Footing Foundations for Light Poles in Area 2A Allowable average bearing capacity 1,500 psf -may be increased by 33%for transient loading conditions, or -may be increased by 33%for maximum toe pressure evaluation Allowable lateral passive resistance (EFP) 200 psf/foot of depth of embedment ameO Metropointe Engineers Job No.0-212-100600 Attention: Mr. Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach, California Page 45 In Area 3: Light pole foundations in Area 3 may be pre-bored cast-in-place concrete footings.

Discussions with the landscape architect (NUVIS) and the irrigation engineer (Sweeney and Associates) indicated that an irrigation system consisting of drippers delivering water only to the root systems of drought resistant plants(e.g.,Palos Verdes)is currently proposed. This system apparently would not require an enclosed planter. It is recommended that this system be approved by the RWQCB for the final design. The drip system should be non-pressurized, low-flow irrigation system incorporating feedback to shut itself off if leakage is detected. 6.8 GOTHARD STREET TURN-LANE PAVEMENT DESIGN 6.8.1 Site Preparation Initial site preparation should be carried out in accordance with general recommendations provided in Section 9.0 of this report. Specific recommendations for this component of the development are as follows: Within the proposed paved areas, it is recommended that the existing soil be overexcavated to a minimum depth of 1 foot below the existing grade or below the bottom of the proposed aggregate base layer, whichever is deeper. The bottom of the overexcavation should be observed by the Geotechnical Engineer for conformance with the intent of these recommendations and approved prior to any further construction or fill placement. The soil exposed by overexcavation should be inspected for zones of soft or loose materials to verify a uniform subgrade. If soft or loose or disturbed zones or otherwise unacceptable soils materials (such as non-engineered fill) are encountered at this depth, the overexcavation should extend down to approved, competent material. The overexcavation bottom should be moisture- conditioned to approximately 110 percent of optimum moisture content and compacted to a minimum of 90 percent of the maximum dry density(ASTM D1557)for a depth of at least 6 inches. Design subgrade elevation should then be re-established by placing excavated soil in 6-to 8-inch (uncompacted) lifts free of any debris and/or deleterious materials, moisture conditioned to approximately 110 percent of optimum moisture content, and compacted to at least 90 percent of the maximum dry density. The compaction of the upper 12 inches of the subgrade immediately below the pavement section should be increased to a minimum of 95 percent of ASTM D1557 and the soils should be moisture- conditioned to 110 percent of optimum moisture. ameO Metropointe Engineers Job No.0-212-100600 Attention:Mr.Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach,California Page 48 6.8.2 Pavement Section The proposed flexible pavement section has been evaluated in general accordance with the Orange County Highway Design Manual method of flexible pavement design using a 20-year design life.

Paved areas should be properly sloped and surface drainage facilities established to minimize water infiltration of the pavement subgrade. Curbing adjacent to paved areas should be founded in the subgrade, not the aggregate base, to provide a cut-off which minimizes water migrating into the base course. 6.9 EARTHWORK FACTORS Based on the existing data the amount of volume loss expected during reworking of the existing non-engineered soils cap is expected to vary from about 10 to 15 percent. For the native alluvial soils found in Area 3, the volume changes area anticipated to vary from -3 (shrinkage) to +3 (bulking) percent. ameO Metropointe Engineers Job No.0-212-100600 Attention:Mr.Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach,California Page 49 6.10 SLOPE STABILITY CONSIDERATIONS Natural / cut slopes up to about 60 feet in heigth at a gradient of up to 1.6(H) : 1(V) descend to Sully Miller Lake along the eastern limit of Area 3.

The objective was to design the AFC cross-section utilizing on-site materials so that the resulting percolation through the cover will be less than the percolation through the prescriptive cover as defined by CCR Title 27 - Environmental Protection, paragraph 21090 SWRCB-Closure And Post-Closure Maintenance Requirements For Solid Waste Landfills. Numerical modeling was carried out using a computer code WinUNSAT-H version 1.0 developed at the University Of Wisconsin. The actual calculation engine within WinUNSAT-H which solves one-dimensional Richard's equation for unsaturated flow utilizes code UNSAT-H version 2.0. 7.1.1 Input Parameters . Detailed input parameters for each of the modeled scenarios are included in the Appendix G of this report. The required input parameters include: • Soil layers and their characterization, including water retention and hydraulic conductivity characteristics; 0 Meteorological site characterization, including maximum and minimum air and soil temperature,dew point temperature,solar radiation,average wind speed,and precipitation. • Irrigation information; • Surface vegetation characterization, including Leaf Area Index and root density function; The soil properties in the numerical model are approximated by the van Genuchten water retention constitutive model and with either Burdine or Mualem hydraulic conductivity models. 7.1.2 Cover Configuration The soil cover configuration is modeled by a system of discrete nodes. The alternative cover configuration used in the analyses generally consisted of a system of erosion-resistant or vegetative layer over sand drainage layer(in Area 1)over monolithic soil layer.

The boundary conditions consist of meteorological data representing the conditions at the subject project location. Weather data collected at weather stations located in Long Beach, Santa Ana, Tustin, Irvine, Costa Mesa, Newport Beach, Corona del Mar, and Laguna Beach over at least a 10-year period were reviewed as a basis for the boundary conditions input. Locations of the considered and reviewed weather stations are shown on Plate VI in the back of this report. The weather information was obtained from weather databases of the University of California Integrated Pest Management project (UC IPM) and at Orange County Public Facilities And Resources Department. Data from the Long Beach weather station CIMIS Station #102 El Dorado were selected as the most representative of on-site conditions due to the similar weather station location relative to the elevation and surrounding topography. Precipitation year 1992 with total precipitation of 14.1 inches was used as a representative data -design year-for the simulation as this year's precipitation was above the average of 13 inches. Meteorological averages, i.e.,wind speed,solar radiation, relative humidity, and air and soil temperature were also based on the data collected at the Long Beach weather station. Irrigation information was provided by the irrigation specialist Mr. Lance Sweeney of Sweeney& Associates. Plant information was provided by Metropointe. The proposed turf is Excalibur, Seashore Paspalum with root penetration depth of 12 to 18 inches. 7.2 MODELING RESULTS The focus of the numerical modeling was on assessment of the water percolation rate through the cover system into the underlying landfill materials. Four different scenarios were investigated: • Modeling of existing conditions, i.e., non-engineered soil cap at about 80 percent relative compaction with sparse grasses and no drainage provisions. • Modeling of prescriptive cover as stipulated in§21090 of CCR Title 27. The prescriptive cover consists of 1 foot low-hydraulic-conductivity layer(hydraulic conductivity of less than 1 x10' cm/sec) overlain by 1 foot of erosion-resistant layer. • Modeling of AFC within xeroscaped areas within Area 2B. 0 Modeling of AFC within irrigated turf ball fields in Area 1 ameO Metropointe Engineers Job No.0-212-100600 Attention:Mr.Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach,California Page 53 The objective of the modeling was to demonstrate that the proposed AFC cross-section controls and limits percolation into the underlying waste at least as well as the prescriptive cover. For comparison purposes, the existing condition was also modeled to demonstrate an improvement by installation of an AFC. It is noted that the proposed construction will significantly improve the existing condition and provide a controlled system to limit percolation into underlying materials. Some of the conditions, which are likely to have an appreciable impact on the percolation rates have been conservatively assumed or neglected. Thus, the AFC modeling conservatively neglected significant areas within the development where landfill materials are and will be covered with substantial thickness of inert soil cap, locally more than 20 feet thick. Consequently, only performance of soil cover cross- sections as indicated in the table below was considered. In addition, the drainage layer below the vegetative layer in Area 1 with installed geosynthetic drainage elements was not assumed to remove any water from the system, which is also a conservative assumption. No numerical modeling was deemed necessary for Area 2A, where the asphaltic pavement in combination with periodical maintenance and monitoring schedule is considered to provide superior protection against infiltration.

The grain size distribution of the materials to be used in the construction of the AFC's monolithic layer should fall within the boundaries indicated on Figure 4. These boundaries bracket the range of typical on-site materials considered suitable for use in the construction. Whereas finer gradations may be considered acceptable, coarser gradations would yield higher percolation into underlying waste materials and should be avoided. It is recommended that the grain size distribution of each soil type encountered during grading operations be tested and its suitability for use in AFC construction verified. Review of subsurface information from available borehole logs indicated that the majority of the existing non-engineered soil cap materials are acceptable for use for the AFC. It appears that the majority of these materials are silty sands deposited on the project site from Santa Ana River dredging operations. Another prevailing material type - sandy silt - was found in the northern portion of Area 1.

It is assumed that a zone of at least 4 feet of existing soil cap is left in place to provide separation from landfill materials. It is recommended that the erosion-resistant layer and vegetative layer materials will be derived from on site materials. Materials used for construction of the monolithic layer or other materials acceptable for turf installation may be used for the vegetative layer. The erosion-resistant and vegetative layer materials should comply with the requirements of Article 2 -§21090 a3 of CCR Title 27 Environmental Protection. ameO Metropointe Engineers Job No.0-212-100600 Attention:Mr. Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach,California Page 55 The AFC recommended in this report should comply with all requirements of the CCR Title 27 Environmental Protection. The following paragraphs list some of the most pertinent sections of the Title 27. Maintenance and monitoring program should comply with requirements Article 2-§21090 of CCR Title 27 Environmental Protection-Closure and Post-Closure Maintenance Requirements for Solid Waste Landfills. Drainage plan shall meet the requirements of Article 4 - §20365 SWRCB of CCR Title 27 Environmental Protection- Precipitation and Drainage Controls. Survey monitoring program shall meet the requirements of Article 1 -§20950 SWRCB of CCR Title 27 Environmental Protection - General Closure and Post-Closure Maintenance Standards Applicable to Waste Management Units for Solid Waste. However, it is recommended that at least 3 permanent monuments be installed in each of the Areas 1, 2A, and 213. The locations of the survey monuments should uniformly cover the areas of deeper and shallower landfill materials and soil cover and be located in strategic locations relative to proposed structures. ameO Metropointe Engineers Job No.0-212-100600 Attention: Mr. Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach,California Page 56 8.0 GENERAL DESIGN RECOMMENDATIONS 8.1 FOUNDATIONS AND FLOOR SLABS DESIGN RECOMMENDATIONS • Due to the presence of landfill gases, a vapor barrier, such as a polyethylene membrane, is recommended beneath each building slabs, including the roller hockey and batting cage slab. The polyethylene membrane should be covered with two inches of moist sand to promote concrete curing. The membrane should be underlain by at least 2 inches of moist sand to protect it during construction and to provide a capillary break. This sand should have a sand equivalent of at least 40. • The design of conventionally reinforced slabs-on-grade should be performed in recognition of potential deformation due to both compression of landfill materials and expansive on-site soils. Slabs-on-grade should have a minimum thickness of 6 inches and minimum reinforcement of #4 bars spaced on 24-inch centers in both directions. To minimize differential movement, it is recommended that reinforcement be extended through control joints. Control joints should be spaced at not more than 12 feet on center in both directions and troweled or sawn at least 1 inch deep, but not more than one-quarter of the thickness of the slab. The slabs, and any framing supported on the slabs, should be designed to tolerate the potential movement. The above recommendations are considered minimums only and the project Structural Engineer should be consulted regarding the design of the slab thickness, reinforcing,joint spacing and other details. I 8.2 DRAINAGE CONTROL Control of surface drainage and management of moisture infiltration control is of paramount importance to this project. Irrigation and landscape specialists should contribute to the design to comply with the requirements of the project. The intent of this section is to provide general information regarding the control of surface water. The following recommendations are considered minimal: 0 Ponding and areas of low flow gradients must be avoided. • If bare soil within 5 feet of a building structure is not avoidable, a gradient of at least 2 percent should be provided away from the improvement. Corresponding paved surfaces should be provided with a minimum gradient of 1 percent. • The remainder of unpaved areas, including sporting fields and turf areas, should be provided within a minimum drainage gradient of 2 percent. ame --Y Metropointe Engineers Job No.0-212-100600 Attention:Mr. Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach,California Page 57 • Positive drainage devises,such as graded swales, paved ditches,and catch basins should be used wherever practicable to accumulate and convey water to points of discharge. • Concrete walks and flat-work should not obstruct the free flow of surface water. • Brick-flat-work should be sealed by mortar or be placed over a impermeable membrane. • Any area drains should be recessed below grade to allow free flow of water into the basin. • Enclosed raised planters should be sealed at the bottom and provided with a ample flow gradient to a drainage device. Recessed planters and landscaped areas should be provided with area inlet and subsurface drain pipes. • Planters adjacent to any structures should be avoided wherever practicable. If planters are to be located adjacent to structures, they should be positively sealed, and incorporate a subdrain. Adjacent grade should be such that run-off from adjacent pavement or walks into planted areas is prevented. • Planting areas at grade should be provided with positive drainage. Wherever possible, exposed soil areas should be above adjacent paved grades. Drainage devices and curbing should be provided to prevent run-off from adjacent pavement or walks into planted areas. • Gutter and downspout systems should be provided on structures to capture all discharge from roof areas. The accumulated roof water should be conveyed to off-site disposal areas by a pipe or concrete swale system. • Landscape watering should be performed judiciously to preclude either soaking or desiccation of soils. The watering should be such that it just sustains plant growth without over-watering. An irrigation monitoring and control system should be installed. • Surface water should be controlled so that conditions of uniform moisture are maintained beneath the structure, even during periods of heavy rainfall. • All grading should be periodically reviewed to determine if settlement of the landfill materials beneath the site has significantly altered the functioning of any drainage features. ameO Metropointe Engineers Job No.0-212-100600 Attention:Mr.Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex,Huntington Beach,California Page 58 8.3 UTILITY INSTALLATION Utility installation throughout the sports complex must be considered in view of the environmental goals that have to be met. Utility installations include electrical, water, gas, sewer, storm drains, and communication services. Electrical services will be required for security lighting in the parking lot and for night time activities on the sporting fields. General electrical services will be required for the maintenance areas, restrooms, tot lots and concession buildings. Water services will be i required for use in restrooms, concession buildings and for personal consumption from drinking fountains. Water will also be required for irrigation both in box planters, for the turf and other landscaping on the sporting fields and at the project boundaries. The use of recycled water for irrigation may be considered,however,this will not influence the general design recommendations for the distribution network. Gas service likely will be required for use in the restrooms and the concession buildings. Sewer services will be required for restrooms,concession buildings,drinking fountains, and maintenance areas. Telecommunications services will be required at all facilities and for remote monitoring locations around the sports complex. Underground utilities are typically installed in trenches that may become conduits for the movement of landfill gases on the site. Landfill gas may also enter breaches in utilities such as electrical or communications cables and vent into electrical control cabinets causing a potential fire hazard. In addition to uncontrolled venting, underground water utilities may cause uncontrolled release of water into the landfill areas through breaks in pressure lines. The presented general design recommendations should be considered minimal and are not intended to override existing state, county and local codes for installation but rather to supplement the codes in order to account for the particular conditions encountered at the site. Subsurface conditions in Area 2A and 213 over the former municipal refuse landfill, and in Area 1, over the former inert debris landfill, will require special design considerations. The area to the southwest has no special conditions with respect to installation of services and construction of light standards and other structures. 8.3.1 Electrical Installations Conduits should be installed at a nominal depth of at least 18 inches below the final grade. Electrical conduits should be constructed of a material that will maintain its integrity in the case of differential ground settlement. A water-and vapor-tight fitting should be connected to the conduit at the point of emergence from the subsurface to prevent landfill gasses and moisture from entering the electrical fitting in the event of a breach of the underground conduit. A conduit monitoring port may need to be installed below the vapor seal in the conduit. The monitoring port could be used to check the integrity of the conduit by means of a pressure test or by means of a vapor analysis. All above ground conduit should be housed in suitable structures that will prevent unauthorized access. All electrical conduits should be installed according to current electrical codes. amedy Metropointe Engineers Job No.0-212-100600 Attention:Mr. Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex,Huntington Beach,California Page 59 8.3.2 Irrigation System Engineering controls on the irrigation system are recommended to provide a means of monitoring and prevent excessive watering. Engineering controls should include moisture sensors installed underground at strategic locations within the development. The moisture sensors should be installed in the vegetative layer and should control the irrigation system by overriding the sprinkler timers as necessary. This may occur due to unseasonal precipitation, extreme evaporation or unusual ambient temperature. In Area 1, moisture sensors should also be installed deeper in the soil cover to monitor soil moisture at different depths within the cover. These sensors are intended for monitoring the water content of the engineered cover and to provide an early warning if excessive percolation of water occurs. The following items should be also considered in the irrigation system design: • Water pipes should be used to transfer irrigation water from the irrigation control center to the box planters located in the islands throughout the parking lot. • The water pipes and pipe connections should be selected so they will maintein integrity under the influence of settlement of the landfill. • It is recommended that the irrigation system be controlled from valves and controllers mounted above ground in a central location instead of underground at various branch locations. • All underground pipes in the irrigation system should only be pressurized while in use to prevent unnoticed leaking. A system of flowmeters should be installed to monitor the integrity of the irrigation system. • All pressurized underground piping in Areas 1 and 2 should be double-walled and have leak detectors installed in the interstitial space. The leak detectors should be connected to shut off valves located at the boundary of the fill area. Alternative irrigation systems,e.g.,single walled flexible piping, may be implemented upon approval by the regulatory agencies. • Operating manuals highlighting the special requirements of the irrigation procedures for the sporting fields over the landfill areas will be required. Grounds-keepers should be trained to comply with the special irrigation procedures. ameO Metropointe Engineers Job No.0-212-100600 Attention:Mr.Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach, California Page 60 8.4 SOIL CORROSION EVALUATION AND RECOMMENDATIONS 8.4.1 Concrete Laboratory tests indicate that the corrosion potential of the on-site soils to concrete is moderate based on 1997 UBC Table 19-A-4. Therefore, Type II, IP(MS)or IS(MS)cement with a maximum water-cement ratio of 0.5 and minimum compressive strength of 4,000 psi is recommended for all concrete that comes in contact with on-site soils. Any imported fill materials should be tested to confirm that the conditions are not more severe than those assumed. 8.4.2 Metallic Laboratory tests indicate that the on-site soils have a very low minimum electrical resistivity,which may present a severe corrosivity potential to buried metal. Such conditions would dictate that a corrosion specialist be consulted regarding suitable types of piping and necessary protection for underground metal conduits. 8.5 TURF DESIGN The turf design should be carried out by a specialist and should be based on the Agricultural Suitability Report prepared by Soil and Plant Laboratory, Inc. and included in Appendix F. 8.6 GEOTECHNICAL CONSIDERATIONS FOR LANDFILL GAS COLLECTION SYSTEM Geotechnical design considerations for the landfill gas collection system in Areas 2A and 213 include the following: • The system of vertical wells and the lateral and header pipes should be able to accommodate total and differential settlement on the order of 6 inches and 3 inches in 5 feet, respectively.. • A drill waste disposal plan should be prepared for excavation of the proposed 24-inch diameter vertical extraction wells. Significant volumes of landfill materials will be excavated. SCAQMD permit will be required for the installation of the wells. • Difficult drilling conditions should be anticipated for all boreholes advanced within the landfill areas. Casing installation may be required if caving is encountered. • The design of the grid of vertical extraction wells needs to consider that the lateral limits of the landfill are not vertical and that only a limited penetration through landfill materials may be achieved along the landfill perimeter, specifically along Golden West Street. ame& Metropointe Engineers Job No.0-212-100600 Attention:Mr. Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex,Huntington Beach,California Page 61 • The design of vertical extraction wells and connections to horizontal collection pipes should consider the potential for development of negative friction due to subsidence of soil cover and landfill materials. ameO Metropointe Engineers Job No.0-212-100600 Attention:Mr. Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach,California Page 62 9.0 CONSTRUCTION CONSIDERATIONS 9.1 GENERAL SITE GRADING All site grading operations should conform with the applicable local building and safety codes and to the rules and regulations of those governmental agencies having jurisdiction over the subject construction. The grading contractor is responsible to notify governmental agencies, as required, and the Geotechnical Engineer at the start of site clean-up, the initiation of grading and at any time that grading operations are resumed after an interruption. Each step of the grading should be approved in a specific area by the Geotechnical Engineer and, where required, by the applicable governmental agencies before proceeding the subsequent work. A site and project specific Health and Safety Plan should be prepared and a environmental monitoring program implemented to reflect the specific nature of the project site. The following site grading recommendations should be regarded as minimal. All site grading recommendations should be incorporated within the project plans and specifications. • Prior to the placement of any fill or construction of foundations or other improvements, all vegetation, oversized material, trash, existing structures, utilities, existing pavements and other obstructions within the grading area should be abandoned in compliance with current governmental regulations and with approval of the Geotechnical Engineer.,or removed and disposed off-site or to designated on-site areas. • Subsequent to clean-up operations,and prior to initial grading orfill placement a reasonable search should be made for subsurface obstructions and the subgrade should be verified by the Geotechnical Engineer for conformance with the intent of the recommendations and approved prior to any further processing. This search should be conducted by the contractor with advice from and under the observation of the Geotechnical Engineer. • Prior to the placement of fill or pouring foundations, the subgrade should be prepared in accordance with the respective site preparation sections of this Report. • The exposed subgrade and/or bottom of any overexcavation should be observed by the Geotechnical Engineer for conformance with the intent of the recommendations and approved prior to any further processing or fill placement. • Fill should be spread in 6- to 8- inch lifts (uncompacted), and moisture-conditioned and compacted in accordance with the site preparation section of this report. ameO Metropointe Engineers Job No.0-212-100600 Attention:Mr.Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex,Huntington Beach,California Page 63 • Excavated on-site inorganic soils, approved by the Geotechnical Engineer and free of debris or contamination are considered satisfactory for placement as a general fill. 0 Observation and field tests should be performed during grading by the Geotechnical Engineering to assist the contractor in obtaining the proper moisture content and required degree of compaction. Where less than the required dry density is indicated, additional compactive effort and any necessary adjustments in moisture content should be made to obtain the required compaction. Wherever,in the opinion of the Geotechnical Engineer,an unsatisfactory condition is being created, whether by cutting or filling, the work should not proceed in that area until the condition has been corrected. 9.2 OVERSIZE MATERIALS Concrete debris and fragments are commonly found in the near surface materials. Sizes of these materials outside the grain size specifications for the AFC material may not be incorporated into the AFC. In the areas of general fill, cobbles, boulders, and rock or concrete fragments up to 8 inches in dimension may be incorporated in deeper fills provided the percentage of material greater than 4 inches does not exceed 40 percent of the total volume. Sizes greater than 8 inches should not be incorporated in the fill unless they can be placed in windrows at least 10 feet below proposed grade. i ameO Metropointe Engineers Job No.0-212-100600 Attention: Mr.Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach,California Page 64 10.0 PERFORMANCE MONITORING AND MAINTENANCE A comprehensive post-construction maintenance and performance monitoring program plan/manual should be prepared. It is anticipated that initially a comprehensive performance inspection and monument survey will have to be carried quarterly, and less frequently later on, if justified by the observed performance. The manual should specify: 0 Periodic monitoring of settlement monuments installed in strategic locations within the development; • Periodic inspections of the pavement of the parking lot for cracking and subsidence; • Periodic inspections of the sporting fields and turf areas for subsidence; • Periodic inspection of irrigation line controls, flowmeters and moisture sensors; • Periodic inspection of continuity of underground electrical and communication conduits; • Periodic sampling of landfill gas collection and venting system; • Thorough and accurate record-keeping protocols; • Periodic need for maintenance of the parking lot and sporting fields. 10.1 GEOTECHNICAL REVIEW Geotechnical review is of paramount importance in engineering practice. The poor performance of many foundations has been attributed to inadequate construction review. 10.2 PLANS AND SPECIFICATIONS The Geotechnical engineer should review the project plans and specification prior to bidding and construction. Such a review is necessary to see whether or not the recommendations in this report have been effectively implemented. This office is best qualified to make professional interpretation based on the work already performed. Such a review should be reported in writing by the Geotechnical Engineer. 10.3 CONSTRUCTION REVIEW Observation and testing should be performed by the Geotechnical Engineer during construction. It should be anticipated that the substrata exposed by the construction may differ from that encountered in the study test borings.

Site preparation, removal of unsuitable soils, imported fill materials, fill placement, foundation installation, and other site grading operations should be observed and tested. ameO Metropointe Engineers Job No.0-212-100600 Attention:Mr.Kelly Nolan November 28,2000 Geotechnical Report-Central Park Sports Complex, Huntington Beach,California Page 66 11.0 CLOSURE This report is based on the project as described and the information obtained from exploratory borings at the locations indicated on the plan. Our findings are based on the results of the field, laboratory and office studies performed by AMEC,and on review of previous site investigations and reports performed by others. The results of our study are based on interpretation and interpolation of soil conditions between test borings and the results reflect our interpretation of the limited direct evidence obtained. Our firm should be notified of any pertinent change in the project or foundation plans. If foundations conditions are found to different from those described here, it may require a reevaluation of the recommendations. Our recommendations for this site are, to a high degree, dependant upon proper quality control of fill placement and foundation installation. Consequently, our foundation recommendations are made contingent upon the opportunity for AMEC to observe grading operations and foundation excavations for this phase of construction. If parties other.than AMEC are engaged to provide such services, they must be notified that they will be required to assume complete responsibility for the geotechnical phase of the project by concurring with the recommendations in this report of providing alternative recommendations. This report has not been prepared for use by.parties or projects other than those named or described above . It may not contain sufficient information for other parties or other purposes.
