SUBJECT: Adopt 2005 Water Master Plan and Financing Plan and Amend
Ordinance 3496 to Replace the 2000 Water Master Plan
Statement of Issue,Funding Source,Recommended Action,Alternative Action(s),Analysis,Environmental Status,Attachments)
Statement of Issue: Beginning in 2004, staff and a consultant began work on an update of
the Water Master Plan. A draft of the plan was presented to City Council at the February 21,
2006 Study Session. The final draft of this update was recently completed and the 2005
Water Master Plan and Financing Plan Update is presented for City Council approval.
Funding Source: No funding is required. All revenues are deposited to the Water Master
Plan Fund (507).
Recommended Action: Motion to:
1. Adopt Resolution No. 2006-�*, adopting the 2005 Water Master Plan;
2. Adopt Ordinance No.37-JO , which would amend HBMC Sections 14.12.010 (d) and
14.12.040, in order to provide that Water Master Plan Capital Facilities Charge and
Capital Surcharge monies shall be used for projects consistent with the goals and I
objectives of the 2005 Water Master Plan, which are specifically identified in a
resolution, and any amendment to same, adopted by the City Council; and
3. Adopt Resolution No. 2006- 31 , which identifies the specific water projects from
the 2005 Water Master Plan upon which WMP Funds can be spent.
Alternative Action(s): Do not adopt the 2005 WMP at this time and direct staff on how to
proceed.
REQUEST FOR COUNCIL ACTION
MEETING DATE: 6/19/2006 DEPARTMENT ID NUMBER: 06-028
Analysis:
The original WMP was adopted in 1988 as a tool to assist in planning for adequate water
service to keep pace with growth and to correct system deficiencies. The plan was originally
unfunded and was supplemented in 1990 and 1993. In 1995, the plan was updated and a
financing plan was put in place to fund the identified capital projects on a pay-as-you-go
basis. Specifically, funding was to be provided by:
1. A capital facilities charge on new residential development of $2,400 per each 3/-inch
meter equivalent capacity installed, and
2. A capital surcharge that is charged on each monthly municipal services (water) bill.
The capital surcharge was originally set at $3.00 per 3/-inch meter and was programmed to
ramp up 50 cents each year to the current $5.50. The surcharge is scheduled to decrease to
$2.00 on December 1, 2007. The $2.00 charge is intended to remain in perpetuity to provide
operations and maintenance funds for the Master Plan facilities constructed.
The WMP was last reviewed and updated in 2000 and adopted by City Council in April 2001.
Beginning in 2004, staff and a consultant began work on another update and review of the
Master Plan, the projects therein, and the Financing Plan. This update was substantively
completed in late 2005. A draft of the plan was presented to City Council at the February 21,
2006, study session.
The WMP is comprised of six chapters that examine and analyze various aspects of the
City's water system and any deficiencies that have been identified, taking into account those
Master Plan projects that have already been completed:
1. City Characteristics and Projected Growth
1. Water Demand
2. Water Supply
3. Water System Facilities and Operation
4. Water Storage and Emergency Supply
5. Water Distribution
Chapter 7 focuses on the Financing Plan and the remaining projects along with revised cost
estimates. Based on current cost estimates and projected revenue, a shortfall in funding of
$3,627,000 is projected. The main reason noted for the shortfall is the recent sharp increase
in construction costs. Three alternative solutions for addressing the shortfall are noted.
1. Adopt the WMP as presented, closely monitor project cost and revenue and revisit the
shortfall issue by mid-2007 and make any appropriate policy and/or financial
adjustments at that time.
2. Suspend the surcharge decrease by one year. By suspending the scheduled
December 1, 2007 surcharge decrease of $5.50 to $2.00 by one year, sufficient
revenue to meet the shortfall will be realized.
3. Eliminate some scheduled projects or consider alternative funding sources.

REQUEST FOR COUNCIL ACTION
MEETING DATE: 61l9/2006 DEPARTMENT ID NUMBER: 06-028
Because of the current volatility of construction costs, staff and the consultant recommend
Alternative 1. If it is determined in mid 2007 that there is still a shortfall in the WMP, then it is
recommended that staff explore using the Water Fund to pay for the relatively small amount
of remaining project work.
In addition to the update of the Master Plan, and in conjunction with the process, a Water
Security Plan was completed. The Water Security Plan was undertaken based on an
Environmental Protection Agency mandated and grant funded Water System Vulnerability
Assessment completed by the City in 2003. While the plan outlines security improvements to
City's water system facilities, these improvements have not been included in the WMP and
will instead be funded through the City's Water Fund.
Public Works Commission Action:
The Public Works Commission reviewed the final draft as an informational item on April 19,
2006. The Commission determined that a recommendation of support to the City Council
was appropriate on a 6-0-1 vote (Scheid absent).
Environmental Status: Not applicable. Implemented projects will comply with the
California Environmental Quality Act.

change of ownership or occupancy.
Where the owner or occupant requests temporary turnoff of water service, a charge of five dollars
($5) shall be made for restoring the water service to the premises. (697-12/57, 1996-8175)
legisdrft/MC 1412-LD 3
14.12.110 Water rates--Turn on. Whenever the distribution line of the municipal water system
shall be duly connected with the premises of any person, and the water turned on such premises,
the charge for water shall be a charge against the person in possession of the premises who used
the water, and the charges shall continue so long as the water is turned on to the premises,
whether the same is actually used or not. (674-12/57)
14.12.120 Water billing. All water bills are due upon presentation and are payable at the Office
of the Treasurer of the City of Huntington Beach, or his authorized agent. Bills are deemed
presented if addressed to the water customer at the address shown on the records of the City
Treasurer and deposited with the United States mail service,postage prepaid. Accounts which
remain unpaid thirty(30) days thereafter are delinquent. A notice of final billing shall be mailed
to each delinquent account specifying a date by which full payment is due. Said final billing
shall include a late fee imposed to recover billing and mailing costs, set by resolution of the City
Council.
Water service for delinquent accounts shall be shut off until all outstanding bills, fees, utility
taxes and penalties have been paid. When the supply of water has been shut off for nonpayment
or a violation of any ordinance or of any rule or regulation, service shall not be resumed until a
turn-on fee, as set by resolution of the City Council, has been paid. (674-12/57, 1996-8/75,2400-11/79,
2589-1/83)
14.12.130 Vacating premises. Whenever a consumer shall vacate any premises,he shall
immediately give written notice thereof to the Water Department. Upon the receipt of such
notice, the department shall read the water meter, shut off the water from the premises and
immediately present the consumer all unpaid bills for water furnished by the City to him up to
that time. Thereupon the consumer shall pay said bills to the Water Department. In the event
that the consumer shall have made a deposit with the department, as required in Section
14.12.090, the balance, if any, of such deposit shall be returned to the consumer after deducting
therefrom the amount of said bills. Until such notice and payments shall have been made, the
premises shall be deemed occupied by the consumer and his liability continued. (674-12/57)
14.12.140 Change of address. Failure to receive mail will not be recognized as a valid excuse
for failure to pay water rates when due. Change in occupancy of property supplied with City
water, and changes in mailing addresses of consumers of City water must be filed in writing at
the Water Department on forms provided for that purpose. (674-12/57)
14.12.150 Renewing service. Each owner or occupant of any premises previously connected
with the City water system desiring to renew the use of water shall make application for renewal
of water service and upon payment of all unpaid charges, if any,together with any turn-on charge
imposed by Section 14.12.100, the water will be turned on. (674-12/57)
14.12.160 Adjustment of rates. The Council shall have the sole power to grant rebates from the
rates specified in this chapter to indigent persons, and in the event of any dispute as to the water
rate to be paid by any consumer, it shall determine the same. (674-12/57)
14.12.170 Water fund. All moneys collected from fees and charges under Chapters 14.04
through 14.20 of the Huntington Beach Municipal Code shall be deposited in the treasury of the
City in a water fund and annually there shall be disbursed from said water fund to the general
fund, an amount equal to fifteen (15%)percent of the gross revenue received from the sale of
water by the Water Department in lieu of franchise and property taxes. (738-12/59,1927-8/74)

The financial analysis finds that the cash balance in the Water Master Plan Fund plus annual revenues
may not be sufficient to pay for all remaining master plan projects and O&M expenses related to these
capital projects. At the end of the analysis period, 2010/11, the Water Master Plan Fund could
potentially have a negative ending balance of$10,269,000 as shown in Table E-2.
The potential negative ending balance results from current costs being higher than original budget
estimates, which is attributable to a number of factors including substantial increases in the costs of `-
materials,contract staffing for design and inspection,and unknown and unclear field conditions.
However, considering that $34.7 million has been spent to date on water master plan projects since
1995 and an estimated $57.4 million remains to complete all master plan projects by 2010/11, the
estimated potential shortfall of$10.3 million only translates to an overrun of approximately 13% over
15 years.
Also, the estimated shortfall of $10.3 million may be significantly reduced because some of the
scheduled cast iron main replacements may be accomplished via development projects, and because
pipeline corrosion control project costs may be reduced as a result of innovative and modern corrosion
control technologies.

TETRATECH, INC.
in association with
Bartle Wells Associates
Executive Summary
E.1 Purpose
The purpose of this report is to update the City's water master plan and water financing plan, which
were last updated in December 2000 and in February 2001,respectively. In conjunction with the 2005
Water Master Plan and Financing Plan, a 2005 Water System Security Plan was prepared by Tetra
Tech and was submitted to the City as a separate report in January 2005.
The Water Master Plan evaluates water system performance and facilities for the planning period 2005
through 2025. The project includes the evaluation of City growth, water demands, water use
efficiency, water supply, proposed new water quality regulations, water storage, emergency water
supply, and water system distribution.
The Water Financing Plan evaluates the costs, scheduling and financing of projects remaining to be
paid for in the City's Water Master Plan Capital Improvement Program (CIP). These projects were
recommended in previous City water master plans.
E.2 City Characteristics and Projected Growth
Of the 17,231 acres of land within the City boundaries, only 3% of the City remains as vacant land
(520 acres). Of this vacant land, approximately 25%is zoned residential,24%is zoned industrial, and
18% is zoned open space parks. It is estimated that all of this land will be developed ultimately with
the exceptions of land to be left vacant per City Specific Plans and vacant land in the open space
conservation category.
The City's population is projected to increase from 198,043 in 2004 to 222,274 in 2025 (12.2%),with
total dwelling units(DUs)increasing from 77,221 to 80,297(4.0%). The percentage of vacant DUs in
the City has been 2.65% since the year 2000. The number of people per occupied DU (population
density) was 2.63 in 2004. If it is assumed that the vacancy percentage remains 2.65% in 2025, then
the population density would increase to 2.84 in 2025, an 8.0%increase.
E.3 Water Demand
Historical Water Demands
City water demands have not changed significantly over the past decade even though development has
occurred and the City's population has increased during this time. City potable water supply for the 8
water years 1996/97 through 2003/04 averaged 34,462 acre feet per year(afy). Note that a water year
is July through June, whereas the City's fiscal year is October through September. For this same
period, City water consumption as developed from City billing records averaged 32,266 afy.
Unaccounted-for water, which is the difference between water supply and water consumption and
represents"lost"water,averaged 2,197 afy(6.4%of water production).
Unaccounted-for water was 9.9% in 1995/96, but has averaged 6.4% since 1996/97. The decrease in
unaccounted-for water can be in part attributed to a leak detection survey conducted for the City in
1996/97. The California Urban Water Conservation Council recommends a complete distribution
system audit if unaccounted-for water exceeds 10%. With the City currently averaging a little over
6%,an audit is not needed.
CITY OF HUNTINGTON BEACH TETRA TECH,INC.
2005 Water Master Plan and Financing Plan E-1
Executive Summary
Total water use per person in the City has historically been less than total water use per person in
Orange County. For comparison, the City averaged 164 gallons per capita per day (gpcd) from
1996/97 through 2003/04 compared with 208 gpcd for the Municipal Water District of Orange County
(MWDOC) service area (all of Orange County not including the cities of Anaheim, Fullerton, and
Santa Ana).
Existing and Projected Water Demands
City potable water supply averaged 21,250 gallons per minute (gpm),which is 34,300 afy, over the 5-
year period 1999/00 through 2003/04 and this could be taken to be the average water demand for the
City's "Existing System". Per capita water use for this 5-year period was 158.5 gpcd. However, City
per capita water use has been higher in past years when there was low rainfall. In 1990/91, the fifth
year of a 6-year drought, City per capita demand was 170 gpcd. In 1996/97, the second of two
consecutive low to moderate rainfall years, City per capita demand was 172 gpcd. For the purpose of
analysis,City potable water demands were increased 8.5%to 23,100 gpm(37,200 afy)for the Existing
System in order to evaluate water system performance during low rainfall periods.
Water demands for the year 2025, which represents the Ultimate System for the planning period, are
estimated to increase 6.4%to 24,800 gpm (39,900 afy)by estimating that all developable vacant land
will be developed and by increasing residential water demands by 4.0% to account for the projected
8.0%increase in population density.
Maximum-day demand factors, which are the ratios of the maximum-day demand to the average day
demand, were estimated to be 1.8 for the entire system and 2.7 for the 800-acre Reservoir Hill area
that constitutes Zone 2 of the water system. The peak-hour demand factors,which are the ratios of the
peak hour demand to the average demand,were estimated at 2.8 for the entire system and 4.7 for Zone
2. These demand factors are slightly higher than the factors developed for the 2000 Water Master Plan
based on new demand information.
Water Use Efficiency
The City became a Signatory to the Memorandum of Understanding Regarding Best Management
Practices for Urban Water Conservation (Urban MOU) in September 2000. The California Urban
Water Conservation Council (CUWCC) has responsibility for monitoring implementation of the
Urban MOU. MWDOC, as a regional wholesaler of imported water, implements many of the Best
Management Practices (BMP) on behalf of its member agencies including the City. As Signatory to
the Urban MOU, the City has committed to using Good Faith Efforts to implement 14 current BMPs.
As a result City water conservation efforts, a downward trend in City water consumption can be seen
especially in regard to residential per capita water consumption.
From 2000/01 through 2003/04, residential per capita water demand averaged 106.5 gpcd, which is
5% less than in 1999/00 (112 gpcd) and 7%less than in 1996/97 (115 gpcd). The downward trend in
residential water use can be attributed in part to water conservation programs undertaken by the City
including public information programs, school education programs, water survey programs, and
plumbing fixture retrofits.
City commercial and industrial water demand decreased approximately 17%from 1996/97 to 2003/04.
Decreased water use for the Commercial and Industrial billing categories can be attributed in part to
the City's participation in regional commercial, industrial, and institutional water-use efficiency
programs. However, the predominant reason for this decrease is the gradual implementation by the
CITY OF HUNTINGTON BEACH TETRA TECH,INC.
2005 Water Master Plan and Financing Plan E-2
Executive Summary
City over the past decade of dual meters in place of single mixed-use meters for commercial and
industrial accounts as well as public and multi-family residential accounts. In using dual meters, one
meter is dedicated to measuring irrigation water use under the Irrigation billing category with the
second meter dedicated to measuring internal water use. The City is employing dual meters in order to
better account for and monitor irrigation water use. In implementing dedicated irrigation meters,
water use as measured in the Municipal and Irrigation billing categories is slightly increased over this
same period. Municipal accounts include all City parks.
EA Water Supply
City water supply has historically come from groundwater production and from supplemental, treated,
imported water purchased from the MWDOC, which is a member agency of the Metropolitan Water
District of Southern California(MWD).
As a member agency of Orange County Water District (OCWD), the City is entitled to groundwater
from the Orange County Groundwater Basin. The City and other basin producers pay a
Replenishment Assessment (RA) to OCWD for all groundwater produced up to a percentage of the
producer's total water supplies used to meet demands. This is called the Basin Production Percentage
(BPP), which is set uniformly for all producers. For 2003/04, OCWD lowered the BPP from 75%to
66%and increased the RA from $127/acre feet(af) to $149/af. For 2004/05,the BPP was unchanged
but the RA was increased to $172/af. OCWD further increased the RA to $205/af and further
decreased the BPP to 64%for 2005/06. The intent of these changes is to lessen groundwater pumping
in order to increase basin groundwater levels.
It benefits the City to use groundwater up to the maximum allowable BPP because groundwater is less
expensive and considered to be more reliable than imported water. City groundwater production cost
approximately$248/af in 2004/05 (including the RA and energy but not including other well operation
and maintenance costs). The City currently purchases supplemental, treated, imported water from
MWDOC for $472.50/af (exclusive of connection fees and readiness to serve charges). City
groundwater production cost will increase in 2005/06 as a result of the RA increasing from $172 of to
$205/af.
The City's water supply has averaged 56% groundwater production and 44% imported water
purchases over the past eight years(1996/97—2003/04). However,the City participates in the In-Lieu
or Cyclic Storage Program offered by OCWD and MWD, when available. In this program, the City
purchases imported water in-lieu of groundwater but at the lower cost of groundwater production in
order to help OCWD replenish the groundwater basin. Accounting for this in-lieu imported water use
as equivalent groundwater use, adjusts imported water use for the City down to 3 1% for this 8-year
period.
With the construction of Well No. 12 in late 2005,the City now has ten active potable water wells that
have a combined capacity of approximately 24,800 gpm. Well No. 1 is scheduled to be re-drilled in
2006 and it is estimated that the capacity of this well will increase from 500 gpm to approximately 750
gpm when this work is completed.
The City has sufficient well capacity to fully utilize the current BPP and it is estimated that this well
capacity will be sufficient to fully utilize the BPP through the planning period. The City also has
sufficient well capacity and imported water capacity to meet all normal demand conditions through the
planning period including average-day demands, maximum-month demands, and maximum-day
CITY OF HUNTINGTON BEACH TETRA TECH,INC.
2005 Water Master Plan and Financing Plan E-3
Executive Summary
demands. City supply capacities plus existing reservoir booster pump capacities are sufficient to
provide for City peak-hour demands through the planning period.
A 50-mgd seawater desalination plant has been proposed at the AES Huntington Beach Generating
Station property. In September 2005,the Huntington Beach City Council approved an Environmental
Impact Report supporting construction of the plant. As of the date of the report's data analysis and
modeling(November 2005),this proposed plant was not considered as a supply source.
Water Quality
The City's water supply consistently meets or exceeds all State and federal potable water quality
standards. Proposed federal water quality regulations on the horizon including a new lower maximum
contaminant level(MCL)for arsenic, an upgraded rule for groundwater disinfection, a MCL for radon,
and new monitoring requirements for disinfectant byproducts are not expected to affect the City's
ability to meet future water quality standards based on historic water quality parameters of the City's
supply sources and the City's current disinfection procedures. However,the City will need to monitor
proposed radon regulations in regard to which radon mitigation program the State chooses to follow.
E.5 Storage and Emergency Supply
The City currently has 55.0 million gallons (MG) of storage capacity located at the Overmyer, Peck,
Springdale, and Edwards Hill storage reservoirs. Booster stations are located at the Overmyer,
Peck/Springdale, and Edwards Hill sites to pump water from the reservoirs into the Zone 1 distribution
system at appropriate pressures. The Reservoir Hill Booster Pump Station, which is located at the
Overmyer site, boosts water from Zone 1 into Zone 2, which does not have a storage reservoir. In
addition to pumping to Zone 1,the Edwards Hill Booster Pump Station also boosts water into Zone 2.
As recommended in the 2000 Master Plan and scheduled in the City's current Water Master Plan CIP,
a 10-MG storage reservoir and an I1,000-gallons per minute (gpm) booster pump station will be
constructed in the southeast quadrant of the City at the AES property to ensure water supply reliability
and storage for the area south of the Newport-Inglewood Fault and south of Bolsa Chica. Currently
there are no storage reservoirs or supply sources located south of the fault and an earthquake on this
fault could potentially sever water transmission and distribution pipelines crossing the fault leaving the
southern portion of the City without potable water. With the construction of this"Southeast Reservoir
and Booster Pump Station",the City will have 65.0 MG of storage capacity.
It should be noted that storage capacity occurs when a reservoir is filled to its maximum level.
However, during a normal operating day, City reservoir levels vary between the maximum and
minimum levels in order to supply water into the system when needed. With this in mind, a total
existing system volume of 55.0 MG is never available at any one time.
It is estimated that the City has sufficient reservoir storage to accommodate operational and fire-
protection storage requirements throughout the planning period.
Emergency storage is reservoir water that is available to satisfy demands when normal supplies are
reduced or unavailable due to unusual circumstances. For the City, normal water supply is from wells
and imported water connections. One way to gauge the magnitude of available emergency storage is
to determine the equivalent number of days of average demand that can be provided. Based on
existing storage, 0.95 days of average demand emergency storage is available. After the construction
CITY OF HUNTINGTON BEACH TETRA TECH,INC.
2005 Water Master Plan and Financing Plan E-4
Executive Summary
of the proposed 10.0 MG Southeast Reservoir, 1.22 days of average demand emergency storage would
be available. These emergency storage volumes, which are calculated based on year 2025 projected
average demand, places the City approximately in the middle of 24 water agencies surveyed by the
City's Department of Public Works in 2001.
Backup water supply can augment storage during a specific emergency water supply scenario. In this
regard, several different emergency storage/supply scenarios were evaluated including a complete loss
of the City's imported water supply coupled with a 7-day electric power outage.
The most likely causes for an imported water outage or reduction in supply would be a break in an
imported water transmission main or mains or an outage at a filtration plant caused by an earthquake.
MWD's "Infrastructure Reliability and Protection Plan (IRPP)" is a program where MWD is
evaluating the reliability of its aqueduct facilities,treatment plants and distribution system.
For example, an outage of the Diemer Filtration Plant,which treats imported water for Orange County
cities including Huntington Beach, is estimated to have a recover time of 31 days. Repairs on the East
Orange County Feeder No. 2, one of the major transmission pipelines conveying imported water to the
City, is estimated to take 10 days. For Orange County, the most significant risk to imported water
supply is believed to be movement of the Whittier-Elsinore fault system.
It was determined that the City has sufficient emergency storage, groundwater supply, and emergency
power to withstand an imported water outage of 31 days or longer coupled with an electric power
outage lasting the first 7 days of the emergency scenario.
Another possible emergency scenario is a complete loss or a reduction in the City's groundwater
supply from the Orange County Groundwater Basin, conceivably as a result of basin groundwater
contamination. It was determined that the City has sufficient emergency storage and imported water
supply to withstand this emergency scenario also.
E.6 Water Distribution
The City's existing hydraulic network model was created by the City in 1998 to analyze City water
distribution performance. For this water master plan, the City's model was updated with upgraded
H2ONET software, which was then used to improve the connectivity of the model. Pipelines
constructed since the year 2000 were entered into the model, as were new updated water demands.
The upgraded and updated model was then used to simulate and analyze distribution system
performance for the existing water system and for the year 2025 water system. Service pressures
throughout the water system were found to be good for average-day and peak-hour demand conditions
for the existing system and for the year 2025 system.
Fire flow is the flow rate of a water supply that is available for fire fighting at a residual pressure of 20
psi. City fire flow requirements are set by the City Fire Department and are based on the current
Uniform Fire Code (UFC). A Fire flow of 1,000 gpm was run in the model at each City fire hydrant
location to gauge fire flow strength in terms of residual pressure. A 1,000-gpm fire flow represents
the minimum UFC fire flow for one and two-family dwellings having a fire area less than 3,600 square
feet. For the next iteration in the fire-flow analysis, the fire flow at each hydrant was increased to
1,500 gpm. As a third step in the analysis,the fire flow at each hydrant was increased to 2,000 gpm.
CITY OF HUNTINGTON BEACH TETRA TECH,INC.
2005 Water Master Plan and Financing Plan E-5
Executive Summary
The analysis showed that a residual pressure of 20 psi could be attained at most hydrants in the system
at fire flows up to 2,000 gpm. However, a residual pressure of 20 psi could not be attained on a
number of hydrants that are located at the end of dead-end 6-inch water mains at fire flows of 1,500
gpm and 2,000 gpm. These 6-inch dead-end hydrants are typically located in residential areas. Also,
a 6-inch water main in North Pacific Avenue in Sunset Beach (approximately 1,700 linear feet long)
might need to be replaced with a larger diameter pipeline and/or cross connections might need to be
made to the 8-inch main in Pacific Coast Highway and/or the 10-inch main in South Pacific Avenue in
order to meet fire flow requirements.
The purpose of this analysis was to provide the City with an indication of where fire flow deficiencies
might occur within the City. It is recommended that the City further evaluate the areas with low
residual pressures in consultation with the City Fire Department and then possibly conduct more
detailed analysis to determine if fire system and/or water system improvements are required.
E.7 Financing Plan
Updated cost estimates and scheduling were developed for projects remaining to be paid for in the
City's Water Master Plan CIP. These projects were recommended in previous City water master
plans. The remaining projects are identified with project numbering from the 2000 Water Master Plan
and financing plan and are described as follows:
Protect Nos. 1 and 15: Beach Boulevard and Downtown Pipe Improvements
Project Nos. 1 and 15 have been combined for this water master plan and financing plan. For
Project No. 1, dead end pipe segments will be connected in spots along Beach Boulevard to
improve water supply and fire flow reliability for corresponding areas fronting this road. For
Project No. 15, improvements will be made to the 20-inch Downtown Loop Transmission
Main to improve supply to the downtown area especially from the proposed Southeast
Reservoir transmission main(Project No. 14 discussed later).
Proiect No. 2: Chlorination UpgLades for Well No. 13
Well No. 13 is a new City well that is currently operating with temporary facilities.
Chlorination upgrades will include chlorine room modifications, some building construction,
and installation of secondary containment vessels.
Proiect No.s: Enery backup S sy tem for Well Nos. 6. 9, and 10
A portable trailer-mounted propane storage vessel will be purchased and vaporizers will be
constructed at Well Nos. 6,9,and 10 so as to provide energy backup supply for these wells.
Proiect Nos.8 and 9:Pipeline Corrosion Protection Stases I and II
Project Nos. 8 and 9 have been combined for this water master plan and financing plan. For
Project No. 8 (Pipeline Corrosion Control- Stage I), corrosion control will be constructed for
various pipelines including the 42-inch OC-35 Transmission Main from Warner Avenue and
Springdale Avenue to Clay Avenue and Huntington Street. For Project No. 9 (Pipeline
Corrosion Control- Stage II), corrosion control will be constructed for various pipelines
including the 36-inch OC-35 Transmission Main on Springdale Avenue from Bolsa Avenue to
Warner Avenue.

2005 Water Master Plan and Financing Plan E-6
Executive Summary
Project No.10:Pipeline Corrosion Protection Stage III
Project No. 10, corrosion control will be constructed for various pipelines, including the 30-
inch transmission main from Clay Avenue and Huntington Street to Newland Street and
Yorktown Avenue. Since corrosion control on existing smaller diameter pipeline is more
costly and intrusive and development projects over time can eliminate some of these areas of
concern, Pipeline Corrosion Control — Stage IV (Project No. 11), as identified in the 2000
Water Master Plan, has been combined with this Stage III project. It is believed that the
original Water Master Plan objective behind corrosion control will have been met after
completion of Stages I to III.
Project No.12: Permanent Wellhead Facilities for Well No. 13
Well No. 13 is a new City well that is currently operating with temporary facilities.Permanent
wellhead facilities will be constructed not including chlorination upgrades, which are listed as
Project No.2.
Proiect No.13:Southeast Reservoir and Booster Pump Station
A 10 million gallon (MG) storage reservoir and an 11,000 gallon per minute (gpm) booster
pump station will be constructed for this water master plan and financing plan in the southeast
quadrant of the City at the AES property to ensure water supply reliability and storage for the
area south of the Newport Inglewood Fault and south of Bolsa Chica.
Project No.14:Southeast Reservoir Transmission Main
A 10,400 linear foot(If) 16-inch to 24-inch distribution/transmission main will be constructed
to distribute water supply to the southeast service area and to transmit water to the Downtown
Loop from the Southeast Reservoir.
Project No.16:Fire Protection Improvements
Water main improvements will be constructed to improve fire flow pressures and supply
reliability in several areas of the City including Peters Landing in Huntington Harbor.
Project No.17: Cast Iron Main Replacement Program
To increase distribution system capacity and reliability, the City will continue to replace cast
iron pipe in the distribution system with new mains made of non-corrosive pipe materials.
Water System Security Improvements
In conjunction with the 2005 Water Master Plan and Financing Plan, a 2005 Water System
Security Plan was prepared by Tetra Tech and was submitted to the City as a separate report.
The recommended water system security improvements will be funded through the Water
Fund CIP and are not included as Water Master Plan projects.

2005 Water Master Plan and Financing Plan E-7
Executive Summary
Table E-1 shows a timeline of the remaining water master plan projects, starting in 2005/06 and
ending in 2010/I1. The total cost for the remaining master plan projects is estimated at $51,244,000.
Costs for design, construction, construction management, and City project management are included.
It should be noted that costs for construction materials and labor have gone up significantly since these
projects were originally estimated between 1995 and 2000. Costs are based on 2005 dollars and are
escalated at an assumed 2.8%annual inflation rate.

In 1995 the City adopted pay-as-you-go financing as the method to pay for the water master plan
projects. Pay-as-you-go financing relies on cash from fund balances and on-going revenues. There is
no borrowing. The City sets aside moneys to pay for water master plan projects in its Water Master
Plan Fund. There are three sources of revenues for the Water Master Plan Fund: capital surcharges,
capital facilities charge, and interest earnings(i.e.,cash received from investments.).
The capital surcharge, which the City Council adopted in 1995, is a flat monthly charge to each water
customer,regardless of water usage. The surcharge was initially set at$3.00 per month per equivalent
dwelling unit (EDU). It increased $0.50 each December 1st through December 1, 2000, when it
became $5.50 per month per EDU. On December 1, 2007, the surcharge will decrease to $2.00 per
EDU and remain at that level in perpetuity to pay for maintenance of facilities built through the master
plan.
CITY OF HUNTINGTON BEACH TETRA TECH,INC.
2005 Water Master Plan and Financing Plan E-8
Executive Summary
The current capital facilities charge is$2,400 per EDU and has not changed since its adoption in 1995.
This charge applies to new residential development connecting to the water system. The City has
entered into development agreements with respect to certain developments in Huntington Beach under
which the developers provide water facilities in lieu of paying the capital facilities charges.
Interest earned on the cash balance (i.e., cash received from investments) in the Water Master Plan
Fund is another source of revenue. For the purpose of the financial analysis, an interest rate of 3% is
used.
The cash flow for the Water Master Plan Fund shows the projection of revenues and expenses
applicable to the remaining water master plan projects. Sources of revenues for master plan projects
are the cash balance in the Water Master Plan Fund, capital surcharges, capital facilities charges, and
interest earnings. Expenses include expenditures on design and construction of master plan projects,
annual O&M expenses related to the remaining master plan projects and city overhead costs allocated
to the master plan. The cash flow projections from 2005/06 through 2010/11 and how the revenues
and expenses are forecasted are shown in Table E-2.
The financial analysis finds that the cash balance in the Water Master Plan Fund plus annual revenues
may not be sufficient to pay for all remaining master plan projects and O&M expenses related to these
capital projects. At the end of the analysis period, 2010/11, the Water Master Plan Fund could
potentially have a negative ending balance of$3,627,000 as shown in Table E-2.
The potential negative ending balance results from current costs being higher than original budget
estimates, which is attributable to a number of factors including substantial increases in the costs of
materials,contract staffing for design and inspection,and unknown and unclear field conditions.
The estimated shortfall of$3.63 million may be significantly reduced because some of the scheduled
cast iron main replacements may be accomplished via development projects, and because pipeline
corrosion control project costs may be reduced as a result of innovative and modern corrosion control
technologies.
Understanding that there are many factors that affect our projected ending fund balance, such as
volatile construction costs, interest rates and the timing of project construction, the following possible
solutions are offered to address the projected negative ending balance:
• Adopt the Water Master Plan as presented. Closely monitor project cost and revenue, revisit
the shortfall issue by mid-2007 as actual project costs are realized, and make any appropriate
policy and/or financial adjustments at that time,if necessary.
• Suspend the surcharge decrease by one year. The Water Master Plan Surcharge is currently
scheduled to decrease from the current $5.50 per equivalent dwelling unit to $2.00 on
December 1, 2007. The $2.00 charge was designed to remain in perpetuity to pay for
operations and maintenance costs for the new facilities constructed with the Water Master
Plan funds. If this decrease were delayed one year to December 1, 2008, it is estimated
sufficient revenue would be realized to meet the projected shortfall.
• Eliminate some scheduled projects from the Water Master Plan. Projects could be eliminated
or, more likely, considered for funding from alternative sources to address the shortfall. For
CITY OF HUNTINGTON BEACH TETRA TECH,INC.
2005 Water Master Plan and Financing Plan E-9
Executive Summary
example, these projects could eventually be constructed through the Water Fund annual CIP
program or from Water Fund reserves,if available.
Consultant and City Staff recommend that the best course of action at this time would be to follow the
first solution highlighted above: to closely monitor project cost and revenue, revisit the shortfall issue
by mid 2007 as actual project costs are realized and make any appropriate policy and/or financial
adjustments then. If it is determined at that time that there is still a shortfall in the Water Master Plan
Fund, then it is recommended that staff explore using the Water Fund to pay for the relatively small
amount of remaining project work.

2005 Water Master Plan and Financing Plan iii
Executive Summary.
E.1 Purpose
The purpose of this report is to update the City's water master plan and water financing plan, which
' were last updated in December 2000 and in February 2001, respectively. In conjunction with the 2005
Water Master Plan and Financing Plan, a 2005 Water System Security Plan was prepared by Tetra
Tech and was submitted to the City as a separate report in January 2005.
The Water Master Plan evaluates water system performance and facilities for the planning period 2005
through 2025. The project includes the evaluation of City growth, water demands, water use
efficiency, water supply, proposed new water quality regulations, water storage, emergency water
' supply, and water system distribution.
The Water Financing Plan evaluates the costs, scheduling and financing of projects remaining to be
' paid for in the City's Water Master Plan Capital Improvement Program (CIP). These projects were
recommended in previous City water master plans.
' E.2 City Characteristics and Projected Growth
Of the 17,231 acres of land within the City boundaries, only 3% of the City remains as vacant land
(520 acres). Of this vacant land, approximately 25% is zoned residential, 24%is zoned industrial, and
18% is zoned open space parks. It is estimated that all of this land will be developed ultimately with
the exceptions of land to be left vacant per City Specific Plans and vacant land in the open space
' conservation category.
The City's population is projected to increase from 198,043 in 2004 to 222,274 in 2025 (12.2%), with
total dwelling units(DUs) increasing from 77,221 to 80,297 (4.0%). The percentage of vacant DUs in
' the City has been 2.65% since the year 2000. The number of people per occupied DU (population
density) was 2.63 in 2004. If it is assumed that the vacancy percentage remains 2.65% in 2025, then
the population density would increase to 2.84 in 2025, an 8.0%increase.
E.3 Water Demand
' Historical Water Demands
City water demands have not changed significantly over the past decade even though development has
t occurred and the City's population has increased during this time. City potable water supply for the 8
water years 1996/97 through 2003/04 averaged 34,462 acre feet per year(afy). Note that a water year
is July through June, whereas the City's fiscal year is October through September. For this same
period, City water consumption as developed from City billing records averaged ,32,266 afy.
' Unaccounted-for water, which is the difference between water supply and water consumption and
represents"lost"water,averaged 2,197 afy(6.4%of water production).
' Unaccounted-for water was 9.9% in 1995/96, but has averaged 6.4% since 1996/97. The decrease in
unaccounted-for water can be in part attributed to a leak detection survey conducted for the City in
1996/97. The California Urban Water Conservation Council recommends a complete distribution
' system audit if unaccounted-for water exceeds 10%. With the City currently averaging a little over
6%, an audit is not needed.
CITY OF HUNTINGTON BEACH, TETRA TECH,INC.
' 2005 Water Master Plan and Financing Plan E-1
' Executive Summary
' Total water use per person in the City has historically been less than total water use per person in
Orange County. For comparison, the City averaged 164 gallons per capita per day (gpcd) from
1996/97 through 2003/04 compared with 208 gpcd for the Municipal Water District of Orange County
(MWDOC) service area (all of Orange County not including the cities of Anaheim, Fullerton, and
Santa Ana).
' Existing and Proiected Water Demands
City potable water supply averaged 21,250 gallons per minute (gpm), which is 34,300 afy, over the 5-
year period 1999/00 through 2003/04 and this could be taken to be the average water demand for the
' City's "Existing System". Per capita water use for this 5-year period was 158.5 gpcd. However, City
per capita water use has been higher in past years when there was low rainfall. In 1990/91, the fifth
year of a 6-year drought, City per capita demand was 170 gpcd. In 1996/97, the second of two
' consecutive low to moderate rainfall years, City per capita demand was 172 gpcd. For the purpose of
analysis, City potable water demands were increased 8.5%to 23,100 gpm'(37,200 afy) for the Existing
System in order to evaluate water system performance during low rainfall periods.
' Water demands for the year 2025, which represents the Ultimate System for the planning period, are
estimated to increase 6.4% to 24,800 gpm (39,900 afy) by estimating that all developable vacant land
' will be developed and by increasing residential water demands by 4.0% to account for the projected
8.0%increase in population density.
Maximum-day demand factors, which are the ratios of the maximum-day demand to the average day
demand, were estimated to be 1.8 for the entire system and 2.7 for the 800-acre Reservoir Hill area
that constitutes Zone 2 of the water system. The peak-hour demand factors, which are the ratios of the
peak hour demand to the average demand, were estimated at 2.8 for the entire system and 4.7 for Zone
' 2. These demand factors are slightly higher than the factors developed for the 2000 Water Master Plan
based on new demand information.
' Water Use Efficiency
The City became a Signatory to the Memorandum of Understanding Regarding Best Management
' Practices for Urban Water Conservation (Urban MOU) in September 2000. The California Urban
Water Conservation Council (CUWCC) has responsibility for monitoring implementation of the
Urban MOU. MWDOC, as a regional wholesaler of imported water, implements many of the Best
Management Practices (BMP) on behalf of its member agencies including the City. As Signatory to
the Urban MOU, the City has committed to using Good Faith Efforts to implement 14 current BMPs.
As a result City water conservation efforts, a downward trend in City water consumption can be seen
especially in regard to residential per capita water consumption.
' From 2000/01 through 2003/04, residential per capita water demand averaged 106.5 gpcd, which is
5% less than in 1999/00 (112 gpcd) and 7% less than in 1996/97 (115 gpcd). The downward trend in
' residential water use can be attributed in part to water conservation programs undertaken by the City
including public information programs, school education programs, water survey programs, and
plumbing fixture retrofits.
' City commercial and industrial water demand decreased approximately 17%from 1996/97 to 2003/04.
Decreased water use for the Commercial and Industrial billing categories can be attributed in part to
the City's participation in regional commercial, industrial, and institutional water-use efficiency
' programs. However, the predominant reason for this decrease is the gradual implementation by the
' CITY OF HUNTINGTON BEACH TETRA TECH,INC.
2005 Water Master Plan and Financing Plan E-2

' Executive Summary
' City over the past decade of dual meters in place of single mixed-use meters for commercial and
industrial accounts as well as public and multi-family residential accounts. In using dual meters, one
meter is dedicated to measuring irrigation water use under the Irrigation billing category with the
' second meter dedicated to measuring internal water use. The City is employing dual meters in order to
better account for and monitor irrigation water use. In implementing dedicated irrigation meters,
water use as measured in the Municipal and Irrigation billing categories is slightly increased over this
same period. Municipal accounts include all City parks.
' EA Water Supply
' City water supply has historically come from groundwater production and from supplemental, treated,
imported water purchased from the MWDOC, which is a member agency of the Metropolitan Water
District of Southern California(MWD).
As a member agency of Orange County Water District (OCWD), the City is entitled to groundwater
from the Orange County Groundwater Basin. The City and other basin producers pay a
' Replenishment Assessment (RA) to OCWD for all groundwater produced up to a percentage of the
producer's total water supplies used to meet demands. This is called the Basin Production Percentage
(BPP), which is set uniformly for all producers. For 2003/04, OCWD lowered the BPP from 75% to
66% and increased the RA from $127/acre feet(af) to $149/af. For 2004/05, the BPP was unchanged
' but the RA was increased to $172/af. OCWD further increased the RA to $205/af and further
decreased the BPP to 64%for 2005/06. The intent of these changes is to lessen groundwater pumping
in order to increase basin groundwater levels.
It benefits the City to use groundwater up to the maximum allowable BPP because groundwater is less
expensive and considered to be more reliable than imported water. City groundwater production cost
' approximately $248/af in 2004/05 (including the RA and energy but not including other well operation
and maintenance costs). The City currently purchases supplemental, treated, imported water from
MWDOC for $472.50/af (exclusive of connection fees and readiness to serve charges). City
' groundwater production cost will increase in 2005/06 as a result of the RA increasing from $172 of to
$205/af.
The City's water supply has averaged 56% groundwater production and 44% imported water
' purchases over the past eight years (1996/97—2003/04). However, the City participates in the In-Lieu
or Cyclic Storage Program offered by OCWD and MWD, when available. In this program, the City
purchases imported water in-lieu of groundwater but at the lower cost of groundwater production in
order to help OCWD replenish the groundwater basin. Accounting for this in-lieu imported water use
as equivalent groundwater use, adjusts imported water use for the City down to 31% for this 8-year
period.
' With the construction of Well No. 12 in late 2005, the City now has ten active potable water wells that
have a combined capacity of approximately 24,800 gpm. Well No. 1 is scheduled to be re-drilled in
2006 and it is estimated that the capacity of this well will increase from 500 gpm to approximately 750
' gpm when this work is completed.
The City has sufficient well capacity to fully utilize the current BPP and it is estimated that this well
' capacity will be sufficient to fully utilize the BPP through the planning period. The City also has
sufficient well capacity and imported water capacity to meet all normal demand conditions through the
planning period including average-day demands, maximum-month demands, and maximum-day
' CITY OF HUNTINGTON BEACH TETRA TECH,INC.
2005 Water Master Plan and Financing Plan E-3
' Executive Summary
' demands. City supply capacities plus existing reservoir booster pump capacities are sufficient to
provide for City peak-hour demands through the planning period.
' A 50-mgd seawater desalination plant has been proposed at the AES Huntington Beach Generating
Station property. In September 2005, the Huntington Beach City Council approved an Environmental
Impact Report supporting construction of the plant. As of the date of the report's data analysis and
modeling(November 2005),this proposed plant was not considered as a supply source.
' Water Quality
' The City's water supply consistently meets or exceeds all State and federal potable water quality
standards. Proposed federal water quality regulations on the horizon including a new lower maximum
contaminant level (MCL) for arsenic, an upgraded rule for groundwater disinfection, a MCL for radon,
' and new monitoring requirements for disinfectant byproducts are not expected to affect the City's
ability to meet future water quality standards based on historic water quality parameters of the City's
supply sources and the City's current disinfection procedures. However,the City will need to monitor
' proposed radon regulations in regard to which radon mitigation program the State chooses to follow.
E.5 Storage and Emergency Supply
' The City currently has 55.0 million gallons (MG) of storage capacity located at the Overmyer, Peck,
Springdale, and Edwards Hill storage reservoirs. Booster stations are located at the Overmyer,
Peck/Springdale, and Edwards Hill sites to pump water from the reservoirs into the Zone 1 distribution
' system at appropriate pressures. The Reservoir Hill Booster Pump Station, which is located at the
Overmyer site, boosts water from Zone 1 into Zone 2, which does not have a storage reservoir. In
addition to pumping to Zone 1,the Edwards Hill Booster Pump Station also boosts water into Zone 2.
' As recommended in the 2000 Master Plan and scheduled in the City's current Water Master Plan CIP,
a 10-MG storage reservoir and an I1,000-gallons per minute (gpm) booster pump station will be
' constructed in the southeast quadrant of the City at the AES property to ensure water supply reliability
and storage for the area south of the Newport-Inglewood Fault and south of Bolsa Chica. Currently
there are no storage reservoirs or supply sources located south of the fault and an earthquake on this
fault could potentially sever water transmission and distribution pipelines crossing the fault leaving the
southern portion of the City without potable water. With the construction of this "Southeast Reservoir
and Booster Pump Station",the City will have 65.0 MG of storage capacity.
' It should be noted that storage capacity occurs when a reservoir is filled to its maximum level.
However, during a normal operating day, City reservoir levels vary between the maximum and
minimum levels in order to supply water into the system when needed. With this in mind, a.total
' existing system volume of 55.0 MG is never available at any one time.
It is estimated that the City has sufficient reservoir storage to accommodate operational and fire-
protection storage requirements throughout the planning period.
Emergency storage is reservoir water that is available to satisfy demands when normal supplies are
' reduced or unavailable due to unusual circumstances. For the City, normal water supply is from wells
and imported water connections. One way to gauge the magnitude of available emergency storage is
to determine the equivalent number of days of average demand that can be provided. Based on
existing storage, 0.95 days of average demand emergency storage is available. After the construction
' CITY OF HUNTINGTON BEACH TETRA TECH,INC.
2005 Water Master Plan and Financing Plan E-4
' Executive Summary
' of the proposed 10.0 MG Southeast Reservoir, 1.22 days of average demand emergency storage would
be available. These emergency storage volumes, which are calculated based on year 2025 projected
average demand, places the City approximately in the middle of 24 water agencies surveyed by the
' City's Department of Public Works in 2001.
Backup water supply can augment storage during a specific emergency water supply scenario. In this
regard, several different emergency storage/supply scenarios were evaluated including a complete loss
of the City's imported water supply coupled with a 7-day electric power outage.
' The most likely causes for an imported water outage or reduction in supply would be a break in an
imported water transmission main or mains or an outage at a filtration plant caused by an earthquake.
MWD's "Infrastructure Reliability and Protection Plan (IRPP)" is a program where MWD is
evaluating the reliability of its aqueduct facilities,treatment plants and distribution system.
For example, an outage of the Diemer Filtration Plant, which treats imported water for Orange County
cities including Huntington Beach, is estimated to have a recover time of 31 days. Repairs on the East
' Orange County Feeder No. 2, one of the major transmission pipelines conveying imported water to the
City, is estimated to take 10 days. For Orange County, the most significant risk to imported water
supply is believed to be movement of the Whittier-Elsinore fault system.
' It was determined that the City has sufficient emergency storage, groundwater supply, and emergency
power to withstand an imported water outage of 31 days or longer coupled with an electric power
' outage lasting the first 7 days of the emergency scenario.
Another possible emergency scenario is a complete loss or a reduction in the City's groundwater
supply from the Orange County Groundwater Basin, conceivably as a result of basin groundwater
contamination. It was determined that the City has sufficient emergency storage and imported water
supply to withstand this emergency scenario also.
' E.6 Water Distribution
The City's existing hydraulic network model was created by the City in 1998 to analyze City water
distribution performance. For this water master plan, the City's model was updated with upgraded
H20NET software, which was then used to improve the connectivity of the model. Pipelines
constructed since the year 2000 were entered into the model, as were new updated water demands.
The upgraded and updated model was then used to simulate and analyze distribution system
performance for the existing water system and for the year 2025 water system. Service pressures
throughout the water system were found to be good for average-day and peak-hour demand conditions
' for the existing system and for the year 2025 system.
Fire flow is the flow rate of a water supply that is available for fire fighting at a residual pressure of 20
psi. City fire flow requirements are set by the City Fire Department and are based on the current
' Uniform Fire Code (UFC). A Fire flow of 1,000 gpm was run in the model at each City fire hydrant
location to gauge fire flow strength in terms of residual pressure. A 1,000-gpm fire flow represents
the minimum UFC fire flow for one and two-family dwellings having a fire area less than 3,600 square
' feet. For the next iteration in the fire-flow analysis, the fire flow at each hydrant was increased to
1,500 gpm. As a third step in the analysis,,the fire flow at each hydrant was increased to 2,000 gpm.
' CITY OF HUNTINGTON BEACH TETRA TECH,INC.
2005 Water Master Plan and Financing Plan E-5
' Executive Summary
' The analysis showed that a residual pressure of 20 psi could be attained at most hydrants in the system
at fire flows up to 2,000 gpm. However, a residual pressure of 20 psi could not be attained on a
number of hydrants that are located at the end of dead-end 6-inch water mains at fire flows of 1,500
' gpm and 2,000 gpm. These 6-inch dead-end hydrants are typically located in residential areas. Also,
a 6-inch water main in North Pacific Avenue in Sunset Beach (approximately 1,700 linear feet long)
might need to be replaced with a larger diameter pipeline and/or cross connections might need to be
' made to the 8-inch main in Pacific Coast Highway and/or the 10-inch main in South Pacific Avenue in
order to meet fire flow requirements.
The purpose of this analysis was to provide the City with an indication of where fire flow deficiencies
' might occur within the City. It is recommended that the City further evaluate the areas with low
residual pressures in consultation with the City Fire Department and then possibly conduct more
detailed analysis to determine if fire system and/or water system improvements are required.
E.7 Financing Plan
Updated cost estimates and scheduling were developed for projects remaining to be paid for in the
City's Water Master Plan CIP. These projects were recommended in previous City water master
plans. The remaining projects are identified with project numbering from the 2000 Water Master Plan
' and financing plan and are described as follows:
Proiect Nos. I and 15: Beach Boulevard and Downtown Pipe Improvements
' Project Nos. 1 and 15 have been combined for this water master plan and financing plan. For
Project No. 1, dead end pipe segments will be connected in spots along Beach Boulevard to
improve water supply and fire flow reliability for corresponding areas fronting this road. For
Project No. 15, improvements will be made to the 20-inch Downtown Loop Transmission
Main to improve supply to the downtown area especially from the proposed Southeast
Reservoir transmission main(Project No. 14 discussed later).
' Proiect No. 2: Chlorination Upgrades for Well No. 13,
' Well No. 13 is a new City well that is currently operating with temporary facilities.
Chlorination upgrades will include chlorine room modifications, some building construction,
and installation of secondary containment vessels.
' Project No.5: EneW backup System for Well Nos. 6. 9, and 10
A portable.trailer-mounted propane storage vessel will be purchased and vaporizers will be
' constructed at Well Nos. 6, 9, and 10 so as to provide energy backup supply for these wells.
Proiect Nos.8 and 9:Pipeline Corrosion Protection Stakes I and II
' Project Nos. 8 and 9 have been combined for this water master plan and financing plan. For
Project No. 8 (Pipeline Corrosion Control - Stage 1), corrosion control will be constructed for
t various pipelines including the 42-inch OC-35 Transmission Main from Warner Avenue and
Springdale Avenue to Clay Avenue and Huntington Street. For Project No. 9 (Pipeline
Corrosion Control- Stage II), corrosion control will be constructed for various pipelines
including the 36-inch OC-35 Transmission Main on Springdale Avenue from Bolsa Avenue to
' Warner Avenue.
' CITY OF HUNTINGTON BEACH TETRA TECH,INC.
2005 Water Master Plan and Financing Plan E-6
Executive Summary
' Project No.10:Pipeline Corrosion Protection Stage III
' Project No. 10, corrosion control will be constructed for various pipelines, including the 30-
inch transmission main from Clay Avenue and Huntington Street to Newland Street and
Yorktown Avenue. Since corrosion control on existing smaller diameter pipeline is more
' costly and intrusive and development projects over time can eliminate some of these areas of
concern, Pipeline Corrosion Control — Stage IV (Project No. 11), as identified in the 2000
Water Master Plan, has been combined with this Stage III project. It is believed that the
original Water Master Plan objective behind corrosion control will have been met after
' completion of Stages I to III.
Project No.12: Permanent Wellhead Facilities for Well No. 13
Well No. 13 is a new City well that is currently operating with temporary facilities. Permanent
wellhead facilities will be constructed not including chlorination upgrades, which are listed as
' Project No. 2.
Project No.13: Southeast Reservoir and Booster Pump Station
' A 10 million gallon (MG) storage reservoir and an 11,000 gallon per minute (gpm) booster
pump station will be constructed for this water master plan and financing plan in the southeast
' quadrant of the City at the AES property to ensure water supply reliability and storage for the
area south of the Newport Inglewood Fault and south of Bolsa Chica.
Project No.14: Southeast Reservoir Transmission Main
' A 10,400 linear foot (If) 16-inch to 24-inch distribution/transmission main will be constructed
to distribute water supply to the southeast service area and to transmit water to the Downtown
' Loop from the Southeast Reservoir.
Project No.16:Fire Protection Improvements
' Water main improvements will be constructed to improve fire flow pressures and supply
reliability in several areas of the City including Peters Landing in Huntington Harbor.
' Project No.17: Cast Iron Main Replacement Program
' To increase distribution system capacity and reliability, the City will continue to replace cast
iron pipe in the distribution system with new mains made of non-corrosive pipe materials.
Water System Security Improvements
In conjunction with the 2005 Water Master Plan and Financing Plan, a 2005 Water System
Security Plan was prepared by Tetra Tech and was submitted to the City as a separate report.
' The recommended water system security improvements will be funded through the Water
Fund CIP and are not included as Water Master Plan projects.

' Executive Summary
Table E-1 shows a timeline of the remaining water master plan projects, starting in 2005/06 and
ending in 2010/11. The total cost for the remaining master plan projects is estimated at $51,244,000.
Costs for design, construction, construction management, and City project management are included.
' It should be rioted that costs for construction materials and labor have gone up significantly since these
projects were originally estimated between 1995 and 2000. Costs are based on 2005 dollars and are
escalated at an assumed 2.8%annual inflation rate.

In 1995 the City adopted pay-as-you-go financing as the method to pay for the water master plan
' projects. Pay-as-you-go financing relies on cash from fund balances and on-going revenues. There is
no borrowing. The City sets aside moneys to pay for water master plan projects in its Water Master
Plan Fund. There are three sources of revenues for the Water Master Plan Fund: capital surcharges,
' capital facilities charge, and interest earnings(i.e., cash received from investments.).
The capital surcharge, which the City Council adopted in 1995, is a flat monthly charge to each water
' customer, regardless of water usage. The surcharge was initially set at$3.00 per month per equivalent
dwelling unit (EDU). It increased $0.50 each December 1st through December 1, 2000, when it
became $5.50 per month per EDU. On December 1, 2007, the surcharge will decrease to $2.00 per
' EDU and remain at that level in perpetuity to pay for maintenance of facilities built through the master
plan.
' CITY OF HUNTINGTON BEACH TETRA TECH,INC.
2005 Water Master Plan and Financing Plan E-8
' Executive Summary
The current capital facilities charge is $2,400 per EDU•and has not changed since its adoption in 1995.
This charge applies to new residential development connecting to the water system. The City has
' entered into development agreements with respect to certain developments in Huntington Beach under
which the developers provide water facilities in lieu of paying the capital facilities charges.
Interest earned on the cash balance (i.e., cash received from investments) in the Water Master Plan
Fund is another source of revenue. For the purpose of the financial analysis, an interest rate of 3% is
used.
' The cash flow for the Water Master Plan Fund shows the projection of revenues and expenses
applicable to the remaining water master plan projects. Sources of revenues for master plan projects
are the cash balance in the Water Master Plan Fund, capital surcharges, capital facilities charges, and
' interest earnings. Expenses include expenditures on design and construction of master plan projects,
annual O&M expenses related to the remaining master plan projects and city overhead costs allocated
to the master plan. The cash flow projections from 2005/06 through 2010/11 and how the revenues
' and expenses are forecasted are shown in Table E-2.
The financial analysis finds that the cash balance in the Water Master Plan Fund plus annual revenues
may not be sufficient to pay for all remaining master plan projects and O&M expenses related to these
' capital projects. At the end of the analysis period, 2010/11, the Water Master Plan Fund could
potentially have a negative ending balance of$3,627,000 as shown in Table E-2.
' The potential negative ending balance results from current costs being higher than original budget
estimates, which is attributable to a number of factors including substantial increases in the costs of
materials, contract staffing for design and inspection, and unknown and unclear field conditions.
' The estimated shortfall of$3.63 million may be significantly reduced because some of the scheduled
cast iron main replacements may be accomplished via development projects, and because pipeline
' corrosion control project costs may be reduced as a result of innovative and modern corrosion control
technologies.
' Understanding that there are many factors that affect our projected ending fund balance, such as
volatile construction costs, interest rates and the timing of project construction, the following possible
solutions are offered to address the projected negative ending balance:
' Adopt the Water Master Plan as presented. Closely monitor project cost and revenue, revisit
the shortfall issue by mid-2007 as actual project costs are realized, and make any appropriate
policy and/or financial adjustments at that time, if necessary..
' • Suspend the surcharge decrease by one year. The Water Master Plan Surcharge is currently
scheduled to decrease from the current $5.50 per equivalent dwelling unit to $2.00 on
' December 1, 2007. The $2.00 charge was designed to remain in perpetuity to pay for
operations and maintenance costs for the new facilities constructed with the Water Master
Plan funds. If this decrease were delayed one year to December 1, 2008, it is estimated
' sufficient revenue would be realized to meet the projected shortfall.
• Eliminate some scheduled projects from the Water Master Plan. Projects could be eliminated
' or, more likely, considered for funding from alternative sources to address the shortfall. For
CITY OF HUNTINGTON BEACH TETRA TECH,INC.
2005 Water Master Plan and Financing Plan I E-9
' Executive Summary
example, these projects could eventually be constructed through the Water Fund annual CIP
program or from Water Fund reserves, if available.
Consultant and City Staff recommend that the best course of action at this time would be to follow the
first solution highlighted above: to closely monitor project cost and revenue, revisit the shortfall issue
by mid 2007 as actual project costs are realized and make any appropriate policy and/or financial
' adjustments then. If it is determined at that time that there is still a shortfall in the Water Master Plan
Fund, then it is recommended that staff explore using the Water Fund to pay for the relatively small
amount of remaining project work.

' Chapter 1 - City Characteristics and Projected Growth
' 1.1 Overview
The City has reached near full development with only 3%.of land remaining vacant. However,
' development and redevelopment projects that are either on-going or planned will affect future water
demands. The City's population is projected to increase 12.2% by 2025 with housing projected to
increase 4.0% and the number of people per household (population density) estimated to increase
8.0%.
1.2 Land Use
' There are 17,231 acres of land within the City boundaries. Existing land use in the City is shown on
Figure 1-1 and is tabulated in Table 1-1. The existing land use presented is from the City's current
General Plan and Specific Plans and from the City's 2004 Vacant land Survey. Land Use presented in
' this water master plan is solely for the purposes of estimating water demands.
As shown in Table 1-1, only 3% of the City remains as vacant land (520 acres). Of this vacant land,
approximately 25% is zoned residential, 24% is zoned industrial, and 18% is zoned open space parks.
' It is assumed that all of this land will be developed ultimately with the exceptions of land to be left
vacant per City Specific Plans and vacant land in the open space conservation category, which is
assumed to remain open space, i.e. no future water demands. -
In addition to the General Plan, the City is currently being developed in accordance with 13 Specific
Plans. The largest Specific Plan currently underway is the Downtown Specific Plan. Projects planned
' or already constructed as part of the Downtown Specific Plan include:
• The Strand — Downtown Huntington Beach, which will include a hotel, restaurants, retail
shops, and office space on 3.5 acres extending from 6`i' Street to Main Street and fronting
Pacific Coast Highway(PCH). The project is scheduled for completion in 2006.
' • Pacific City, a retail center with entertainment and restaurant uses on 31 acres fronting PCH at .
First Street in the downtown. The project could be completed in 2006.
• Hyatt Regency Huntington Beach Resort and Conference Center, which also includes retail, a
' fitness center and spa, is on 38 acres located along PCH. The resort and spa opened in January
2003. A third hotel is planned as a future phase.
' • The Hilton Water Front Beach Resort,which was completed in 1990.
The largest land use in the City is residential at 7,904 acres (approximately 46% 'of the total).
' Approximately 721/o of the residential land use is low density residential (3 to 7 dwelling units (DU)
per acre). Commercial land use is spread out over the City (967 acres). However, a large portion of
the commercial land borders Beach Boulevard from Adams Avenue to Edinger Avenue. The Hyatt
' Regency Huntington Beach Resort and Conference Center and the Hilton Water Front Beach Resort
constitute the majority of the 67 acres of Commercial Visitor land use.
Approximately 430 acres in the City are zoned for Mixed Use, which is a composite of Commercial
' Neighborhood, Commercial General, and Residential including town'homes, garden apartments, and
mid to high-rise apartments. Mixed Use is also designated as either vertical or horizontal integrated

housing. As shown on Figure 1-1, mixed use land use is zoned in the downtown area near the Main
' Pier. The large mixed use area with horizontal integrated housing located between the Seacliff Golf
Course and PCH is being developed in accordance with the Palm/Goldenwest Specific Plan.
' A total of 1,615 acres is dedicated to open space including Open Space%Parks (public parks) and Open
Space/Commercial Recreation. Huntington Central Park is the largest public park in the City.at 249
acres. The Seacliff Golf Course and the Meadowlark Country Club constitute the commercial
' recreation land use in the City at 238 acres.
There are 1,171 acres of industrial land in the City. The largest industrial area is in the northwest
corner of the City where Boeing and the McDonnell Center Business Park are located. A second
phase of the McDonnell Center Business Park (77-acre area) is currently being developed in the area
north of Bolsa Avenue. The second largest industrial area is the Gothard Industrial Corridor that
' borders Gothard Street between Ellis Avenue and Edinger Avenue.
Another industrial area in the City is the Southeast Industrial Area, which is actually a composite of
' industrial, public, and open space conservation zoned land uses. The AES Huntington Beach
Generating Station (power plant) is located in this area. The power plant recently retooled Generating
Unit Nos. 3 and 4 to bring an additional 450 megawatts into the California Electrical grid. A 38-acre
land fill is also located in the Southeast Industrial Area. The County Sanitation District of Orange
' County No. 2 Wastewater Treatment Plant is located in the far southeast corner of the City. Both the
power plant and the treatment plant are large City water users.
The 800-acre Reservoir Hill area that constitutes Zone 2 of the water system is also shown on Figure
1-1. Zone 2 is at higher ground elevations than the rest of the City, which constitutes Zone 1. Water
demand has increased:substantially in Zone 2 over the past 10 years as a result of increased
' development in this area. Zone 2 has approximately 60 acres of vacant land remaining. The Zone 2
area is being developed in accordance with the Holly-Seacliff Specific Plan and the Ellis-Goldenwest
Specific Plan. The majority of the land in Zone 2 is residential. However, there is a relatively large
' industrial area in the vicinity.of Garfield Avenue/Goldenwest Street with a relatively large mixed use
area just south of the Zone 2 industrial area.
' The City also supplies water to Sunset Beach, which is approximately 68 acres of unincorporated land
located off Pacific Coast Highway near Huntington Harbor. Sunset Beach land use is not included in
Table 1-1.
' 1.3 Population and Housing
Historical and projected City population and housing is shown in Table 1-2 and on Figures 1-2 and 1-
3. Between 1980 and 2004, City population and total dwelling units increased 16.2% and 18.8%,
respectively. As provided from the Orange County Projections 2004 (OCP 2004), by the Center for
Demographic Research at California State University, Fullerton (CDR), the City's population is
' projected to increase 12.2% from 198,043 in 2004 to 222,274 in 2025, with total dwelling units (DUs)
increasing 4.0% from 77,221 to 80,297. For comparison, population and total DUs for Orange County
are projected to increase 23.5%and 14.4%,respectively, between 2000 and 2025.
' The percentage of vacant DUs in the City decreased from 6.0% in 1980 to 2.65% in 2000 and has held
at 2.65% through 2004. The number of people per occupied DU (population density) was 2.63 in
' 2004. If it is assumed that the vacancy percentage remains 2.65%in 2025,then the population density

' would increase to 2.84 in 2025, an 8.0% increase. Note that vacant dwelling units are not estimated in
OCP 2004. Increased population density is significant because more people per DU results in greater
' water demand per DU.
For comparison, the population density for Orange County would also increase approximately 8.0% in
' 2025 (relative to the year 2000) based on the OCP projections for population and total DUs and under
the same assumption of a constant vacancy percentage. Huntington Beach has a lower population
density than Orange County as a whole. The Orange County population per total (occupied plus
' unoccupied)DUs was 2.94 in 2000 and is projected to increase to 3.18 by 2025.

' Chapter 2 - Water Demand
' 2.1 Overview
Water demand has not changed significantly over the past decade even though development has
occurred and the City's population has increased during this time. Unaccounted-for water, which is the
difference between water supply and water consumption and represents "lost" water, has decreased
since 1995/96 and this decrease is attributed in part to a leak detection survey conducted for the City in
1996/97. For the purpose of analysis, existing City potable water demands/were increased 8.5% in
' order to evaluate water system performance during low rainfall periods. Water demands are estimated
to increase 6.4% by the year 2025, which represents the Ultimate System for the planning period, as a
result of developed land and a projected 8.0% increase in population density.
' 2.2 Historical Potable Water Production
' Historical potable water production for the 13 "water years" 1991/92 through 2003/04 is shown in
Table 2-1 and on Figure 2-1. The City's water year is July through June, whereas the City's fiscal
year is October through September. The water year format is consistent with the Municipal Water
' District of Orange County (MWDOC) and Orange County Water District (OCWD)requirements. All
historical data presented in this water master plan is in accordance with the City's water year.
Goldenwest #3, Goldenwest # 4, and Meadowlark # 2 are.City wells that produce non-potable water
' (high color) for irrigation. This non-potable water production has been subtracted from the potable
water production in Table 2-1. Goldenwest# 3 was destroyed this year. Test pumping for Well No. 8
and for Well No. 12 and in 1998/99 is also subtracted from potable water production in Table 2-1.
' The affect of rainfall on water demand, primarily irrigation demand, is shown on Figure 2-1. Water
production increased slightly from 1991/92 through 1996/97 following the 6-year drought that ended
in early 1992. Water production dipped significantly in 1997/98 due to the high rainfall experienced
' from an El Nino weather condition. Rainfall between 1998/99 and 2003/04 was less than the 13-year .
average rainfall of 14.5 inches and was as low as 3.5 inches in 2001/02. However, water production
only increased slightly during this 6-year period and held constant in 2001/02 when rainfall was only
' 3.5 inches. This can be attributed in part to the water conservation measures undertaken by the City.
2.3 Historical Water Consumption/Unaccounted-For Water
' Historical City water consumption and unaccounted-for water for the eight years 1996/97 through
2003/04 is shown in Table 2-2 and on Figure 2-2. Water consumption was developed from City
billing records. Unaccounted-for water is the difference between metered water production and
' metered water consumption and represents "lost" water. Unaccounted-for water occurs for a number
of reasons:
' • Water lost from system leaking, i.e. from pipes,valves,pumps,etc.
• The City Fire Department performs hydrant testing to monitor the level of fire protection available
throughout the City and the City Water Department performs hydrant flushing to eliminate settled
' sediment and ensure better water quality. Neither is metered. However, the quantity of water
used is estimated and taken into consideration when calculating unaccounted-for water.
• Water used by the Fire Department to fight fires. This water is also not metered.
• Customer meter inaccuracies. Meters have an inherent accuracy for a specified flow range.
' However, flow above or below this range is usually registered at a lower rate. Meters become less
accurate with time due to wear.

' Unaccounted-for water was 9.9% in 1995/96, but has averaged 6.4% since 1996/97. The decrease in
unaccounted-for water can be in part attributed to a leak detection survey conducted for the City in
1996/97. A total of 498 miles of pipeline was surveyed, with a water loss of approximately 67,000 gpd
' quantified from 17 identified leaks. The annual water loss from these leaks was quantified as
approximately 24.4 million gallons. The City repaired all of the leaks identified in the survey and the
City has since implemented an on-going leak investigation and repair program as a measure to keep
' water losses to a minimum while facilitating cost savings.
All years shown in Table 2-2 are water years (June — July) except 2003/04, which is a fiscal year
' (October— September). Accordingly, July, August, and September for FY 2003/04 are year 2004 and
not 2003. 2003/04 is shown as a fiscal year so that September 2003, which is overstated as a result of
the City switching to monthly meter readings starting in that month, can be omitted. The City read
meters every other month prior to September 2003. Billing was corrected after September 2003.
The California Urban Water Conservation Council recommends a complete distribution system audit
if unaccounted-for water exceeds 10%. With the City currently averaging a little over 6%, an audit is
' not needed.
Average daily per capita municipal and industrial (Per Capita M&I) water demand has been used by
' the water industry to measure and compare mean urban water demand. Per Capita M&I water demand
includes the municipal, industrial, commercial, residential water demand, and unaccounted-for water
associated with each person in the population. It also includes recycled water demand but excludes
' some water usage (such as agricultural usage and replenishment of groundwater storage) which are not
directly associated with the population. Historical Per Capita M&I water demand for the City in
comparison with the MWDOC service area, which is all Orange County not including the cities of
' Anaheim,Fullerton, and Santa Ana, is shown in Table 2-3 and on Figure 2-3.
As shown, Per Capita M&I water demand has averaged 167 gpcd for the City compared with 201 for
the MWDOC service area for the eight year period 1996/97 through 2003/04. The lower water demand

Although Per Capita M&I water demand is still a useful measure for evaluating urban water demand,
' the various demand components evaluated separately can offer a more complete perspective.
Historical City water demands are shown in Table 2-4 and on Figures 2-4, 2-5, and 2-6 for three user
types: 1)residential per capita,2)commercial/industrial,and 3)municipal/irrigation.

' The demand data is from City billing data and does not include unaccounted-for water. Figure 2-4
shows residential (including multi-family residential) demand per person as opposed to total demand
per person as shown in Figure 2-3. Residential per capita demand for the most recent four years
2000/01 through 2003/04 averaged 106.5 gpcd, which is 5% less than in 1999/00 (112 gpcd) and 7%
' less than in 1996/97 (115 gpcd).
Over the past six years, it also appears the residential response of increased water usage in years of
' low rainfall is less severe than in 1996/97. The downward trend in residential water use can be
attributed in part to water conservation programs undertaken by the City including public information
programs, school education programs, water survey programs, and plumbing fixture retrofits.
' CITY OF HUNTINGTON BEACH TETRA TECH,INC.
2005 Water Master Plan and Financing Plan 2-7
' Chapter 2 - Water Demand
' Figure 2-5 shows commercial plus industrial demands based on billing data for these two categories.
Commercial and industrial water demand decreased from 6,601 of in 1996/97 to 5,334 of in 2003/04
(17% decrease). Decreased water use for the Commercial and Industrial billing categories can be
attributed in part to the City's participation in MWDOC's and MWD's regional commercial,
' industrial, and institutional water-use efficiency programs. However, the predominant reason for this
decrease is the gradual implementation by the City of dual meters in place of single mixed-use meters
for metering commercial and industrial accounts as well as multi-family residential accounts. This
gradual implementation has occurred over the past decade.
A mixed-use meter measures total water use (both internal and irrigation water use) as singular water
' use under the Commercial and Industrial billing category. In using dual meters, one meter is dedicated
to measuring irrigation water use under the Irrigation billing category with the second meter dedicated
to measuring internal water use under the Commercial and Industrial billing category. As the City
gradually implements dual meters to replace single mixed-use meters, less water use is attributed to
the Commercial and Industrial billing categories and more water is attributed to the Irrigation billing
category. The City is employing dual meters in order to better account for irrigation water use.
' Figure 2-6 shows municipal plus irrigation demands *based on billing data for these two user
categories. Customers under the Municipal billing category are all City facilities. The majority of
Municipal water is used for irrigating City parks such as Huntington Central Park. Other City facilities
' include City Hall, the Civic Center, and City fire stations. Customers under the Irrigation billing
category include commercial, industrial, and high density residential (such as apartments) with
separate irrigation meters. Seacliff Golf Course is the largest user in the Irrigation billing category.
' Municipal and Irrigation water demand has increased since 1997/98. As discussed above, water use is
gradually being shifted from Commercial, Industrial, and Multi-Family residential accounts to
Irrigation billing accounts as the City implements dual meters in place of single mixed use meters.
' This is a major reason for the upward trend in Irrigation water use.
Also, Irrigation water use is greatly affected by rainfall amounts. Rainfall over the past six years has
' averaged 9 inches per year, which is lower than the historical average of approximately 13 inches per
year. Rainfall in 1997/98 was 31 inches. It does appear that the response of increased water use in
years of low rainfall is much less severe than in past years as evidenced by an increase in water use of
only 4% in 2001/02 when rainfall decreased 75% to 3.5 inches. The City participates in MWDOC's
regional landscape irrigation efficiency programs and institutes irrigation efficiency parameters in the
City Municipal Code.
2.4 Projected Water Demands
City water billing and production data, population data from CDR, land use areas from the City's
General Plan, and vacant land from the City's 2004 Vacant Land Survey were used to develop
Existing System (year 2005) and Ultimate System (year 2025) unit water use factors and demands.
The City provided six years of meter data(1998/99 through 2003/04)for six billing categories. The six
billing categories, which constitute the total water consumption for the City, are similar to the land use
categories used in the City's General Plan.
City domestic water production averaged 21,250 gpm over the 5-year period 1999/00 through 2003/04
' and this could be taken to be the average "existing" system water demand. However, domestic per
capita water demand (total domestic system demand divided by the total population) averaged 158.5
gpcd during this period and domestic per capita water demand has been greater in past years. In
' 1990/91, the fifth year of a 6-year drought, per capita demand was 170 gpcd. In 1996/97, the second of
' CITY OF HUNTINGTON BEACH TETRA TECH,INC.
2005 Water Master Plan and Financing Plan 2-8
Chapter 2 - Water Demand
two consecutive low to moderate rainfall years, per capita demand was 172 gpcd. Domestic per capita
' water demand has declined from 166 gpcd in 1999/00 to 150 gpcd in 2002/03 and the 5-year average
ending in 2003/04 is 158.5 gpcd.
Low rainfall brings higher system demands and the water system must be prepared to supply these
higher demands. Because low rainfall or even a drought condition can occur in any given year, it is
recommended that the Existing System demand be taken as the five-year average demand 1999/00
' through 2003/04 multiplied by a factor of 1.085 (172 gpcd/158.5 gpcd), which results in an Existing
System demand of 23,060 gpm. This Existing System demand is taken to be the average demand in
2005.
As shown in Table 2-5, the billing categories were matched with the land use categories and
corresponding existing land use areas to develop existing unit water use factors and existing demands
based on an"existing system demand of 23,060 gpm. Unaccounted-for water for the 5-year period was
' applied to each water use category so that demands are consistent with water production. Water use
data for unincorporated Sunset Beach is included with City water use data in Table 2-5 using the same
billing categories. Existing average-day water demand for Sunset Beach is 209 gpm.
Demands for the top 13 water users in the City are shown in Table 2-6 based on billing data from the
past five years with the demands increased by a factor of 1.085 to account for a drought condition.
' Eight of the City's top water users were located in their respective water use categories in Table 2-5
and their demands were separated from the general demands developed for each category.
' The AES Huntington Beach Generating Station recently retooled Generating Unit Nos. 3 and 4 and a
"worst case" average demand of approximately 455 gpm has been estimated by AES. This demand is
approximately 80% greater than their average demand over the past five years of 255 gpm. The
demand for the AES power plant was increased from 255 gpm to 455 gpm, increasing the average
demand for the Existing System to 23,260 gpm.
Water use from the Irrigation billing category was apportioned to the various land use categories in
' Table 2-5 based on estimated use for that land use category. Street right-of-ways were apportioned to
each land use category such that unit water use is based on gross acreages. Vacant land totaling 628
acres including right-of-ways was removed from the land use categories and zero demand was
' allocated to vacant land. Global factors were used to adjust demands in the City's H20NET Existing
System hydraulic model consistent with the demand information presented in Table 2-5.
' To project Ultimate System (year 2025) demands, the existing residential unit water use factors were
increased by 4.0% to account for the projected 8.0% population per dwelling unit increase. The
AWWA Research Foundation estimated in 1999 that 45% of residential water use is for interior use
' and 55% is for exterior use. Considering Huntington Beach's moderate coastal climate, it is estimated
that interior and exterior water use is evenly split 50%. It is assumed that more people per household
would only increase interior water use and not exterior use' Accordingly, it is assumed that the
' projected 8.0%population density increase translates to a 4.0%water use per household increase.
The mixed-use land use category is a combination of medium-high to high residential and commercial
land uses. The ultimate unit water use factor for this category was increased by 2.5%to account for the
' projected increase in population density. Unit water use factors for other land use categories were
assumed not to change from the existing values.

1,630 gpm was an increase of 123% since 1997/98. As shown, demand has leveled off because of less
land developed. With only 61 acres left available for development, demand is only projected to

' 2.4.2 Peaking Factors
Just prior to the 2000 Water Master Plan, the City analyzed water production data for the 11 water
' years 1988/89 through 1998/99 and determined that the system maximum-day demand factor during
this period was 1.37 (maximum-day demand/average-day demand) and that the system peak-hour
demand factor was 2.17 (peak-hour demand/average-day demand). Peaking factors used by other area
water purveyors were evaluated in the 2000 Master Plan, and the 1.37 and 2.17 peaking factors were
increased to 1.6 and 2.5, respectively, to provide a 15% safety factor in analyzing Zone 1 system
performance. Maximum-day and peak-hour demand factors of 2.0 and 3.5 were used to analyze Zone
2 system performance based on factors used by other area water purveyors for systems in the
neighborhood of 1,000 gpm. Note that smaller pressure zones have larger peaking factors.
' As part of this water master plan, daily water demands were analyzed for the years 2001 through 2003
to reassess maximum-day demand factors for both the entire system and for Zone 2. The maximum-
day demand for the entire system on July 5, 2002 was 1.55 times greater than the average annual
demand in 2002 and 1.54 times greater than the average demand for 1998/99 through 2002/03. The
' maximum-day demand for Zone 2 on July 3, 2002 was 2.37 times greater than the average annual
demand in 2002. Rainfall in 2001/02 was only 3.5 inches, which is the lowest rainfall total for at least
the past 13 years and is significantly lower than the historical average rainfall of approximately 13
' inches. The maximum-day demands also correlated with increased water use for the Independence
Day holiday. Hourly demand information was not available for analysis.
Based on the new maximum-day demand information, the maximum-day demand factors will be
increased to 1.8 for the entire system and 2.7 for Zone 2 for system analysis in the water master plan
update. These factors include a 15% factor of safety. The peak-hour demand factors will also be
increased proportionally to 2.8 for the entire system and 4.7 for Zone 2.
' With the exception of most irrigation demands, domestic water demands typically peak in the morning
around 6 a.m. to 8 a.m. with a second peak occurring in the evening around 5 p.m. to 7 p.m. These
' peaking times are a little later on the weekends. City golf course and park irrigation typically occurs
between the hours of 10 p.m. and 6 a.m. Because these large irrigation demands peak at a different
time, they were separated from the other domestic water demands in order to more accurately analyze
' peak-hour demands in the hydraulic model. The maximum-day and peak-hour demand factors for the
golf courses and parks is estimated at 2.5 and 7.5, respectively, which is consistent with the factors
reported by other water purveyors in Southern California with an 8-hour irrigation period.

2.6 Water Conservation
tThe City became a Signatory to the Memorandum of Understanding Regarding Best Management
Practices for Urban Water Conservation (Urban MOU) in September 2000. The California Urban
' Water Conservation Council (CUWCC) has responsibility for monitoring implementation of the
Urban MOU. MWDOC, as a regional wholesaler of imported water, implements many of the Best
Management Practices (BMP) on behalf of its member agencies including the City. As Signatory to
' the Urban MOU,the City has committed to using Good Faith Efforts to implement 14 current BMPs.
A BMP as defined in the Urban MOU is a "practice for which sufficient data are available from
t existing water conservation practices to indicate that significant conservation or conservation related
benefits can be achieved; that the practice is technically and economically reasonable and not
environmentally or socially unacceptable; and that the practice is not otherwise unreasonable for most
water agencies to carry out."
MWDOC implements water use efficiency programs on behalf of the City and other member agencies
on a regional basis. MWDOC secures funding from MWD's Conservation Credits Program, the
' United States Bureau of Reclamation, the State Water Resource Control Board, and other sources, to
help implement the BMPs.
The 14 current BMPs are:
BMP 1: Water Survey Programs for Single-Family and Multi-Family Residential
t BMP 2: Residential Plumbing Retrofit
BMP 3: System Water Audits, Leak Detection and Repair
BMP 4: Metering with Commodity Rates for All New Connections and Retrofit of Existing
' Connections
BMP 5: Large Landscape Conservation Programs and Incentives
BMP 6: High-Efficiency Clothes Washing Machine Financial Incentive Programs
BMP 7: Public Information Programs
BMP 8: School Education Programs
BMP 9: Conservation Programs for Commercial, Industrial, and Institutional Accounts
BMP 10: Wholesale Agency Assistance Programs
' BMP 11: Conservation Pricing
BMP 12: Conservation Coordinator
BMP 13: Water Waste Prohibition
BMP 14: Residential ULFT Replacement Programs
Potential BMPs that CUWCC is currently studying for inclusion as a BMP include:
' 1. Rate Structure and other Economic Incentives and Disincentives to Encourage Water
Conservation
2. Efficiency Standards for Water Using Appliances and Irrigation Devices
' 3. Replacement of Existing Water Using Appliances and Irrigation Devices
4. Retrofit of Existing Car Washes
5. Gray water Use
' 6. Distribution System Pressure Regulation
7. Water Supplier Billing Records Broken Down by Customer Class
8. Swimming Pool and Spa Conservation including Covers to Reduce Evaporation

As a result City water conservation efforts, a downward trend in City water consumption can be seen
especially in regard to residential per capita water consumption.
Historical City water demands are shown on Figures 2-7, 2-8, and 2-9 for three user types: 1)
residential per capita, 2) commercial/industrial, and 3) municipal/irrigation. Figure 2-4 shows a
downward trend in residential per capita water use, which can be attributed in part to water
conservation programs undertaken by the City including public information programs, school
education programs,water survey programs,and plumbing fixture retrofits.
' Figure 2-5 shows decreased water use for the Commercial and Industrial billing categories, which can
be attributed in part to the City's participation in MWDOC's and MWD's regional Commercial,
Industrial, and Institutional water-use efficiency programs. However,the majority of this decrease can
be attributed to the advent of more dedicated landscape meters in lieu of mixed-use meters, which has
' decreased water use attributed to the Commercial and Industrial billing categories, while increasing
water use attributed to the Irrigation billing category. This and low rainfall over the past 6 years are
the primary reasons for increased Municipal and Irrigation water demand as shown in Figure 2-6.
The City participates in MWDOC's regional landscape irrigation efficiency programs and institutes
irrigation efficiency parameters in the City Municipal Code. As an additional measure to reduce
' irrigation water use, it is recommended that the City look into retrofitting City parks with weather-
based irrigation timers. Weather-based irrigation timers operate on the principle of scheduling
irrigation based on evapotransportation(ET), which is a function of weather conditions and plant type.
ET is the quantity of moisture that is both transpired by the plant and evaporated by the soil and plant
' surfaces. ET irrigation scheduling systems utilize micro-processing devices that calculate irrigation
schedules based on weather conditions, plant type, and site conditions. Weather-based irrigation
timers adjust irrigation schedules automatically as weather changes, resulting in much higher irrigation
' efficiencies.

' Chapter 3 - Water Supply
' 3.1 Overview
The City's existing sources of potable water supply consist of ten groundwater wells, three imported
' water connections, and three emergency connections with neighboring cities.
Orange County Water District (OCWD) currently allows the City and other Orange County
Groundwater Basin producers to produce groundwater up to a uniform-set percentage of their total
water supplies used to meet demands or to pay a production penalty for groundwater produced above
this percentage. This Basin Production Percentage is currently set at 64%.
' The City also purchases supplemental, treated, imported_water from the Municipal Water District of
Orange County(MWDOC), which is a member agency of the Metropolitan Water District of Southern
California (MWD). The City has historically used more groundwater production than imported water
' purchases to meet demands. City groundwater production is less expensive than the purchase of
imported water.
The City's water supply consistently meets or exceeds all State and federal potable water quality
' standards. The City maintains a water-quality monitoring program consistent with State of California
Department of Health Services (DHS)requirements.
3.2 City Water Supplies
As a member agency of OCWD, the City is entitled to groundwater from the Orange County
Groundwater Basin. The basin, which is managed by OCWD, is imajudicated. The City and other
basin producers pay a Replenishment Assessment(RA) to OCWD for all groundwater produced up to
a percentage of the producer's total water supplies used to meet demands. This is called the Basin
Production Percentage(BPP),which is set uniformly for all producers.
For 2003/04, OCWD lowered the BPP from 75% to 66% and increased the RA from $127/af to
$149/af in consideration of low groundwater levels. For 2004/05, the BPP was unchanged but the RA
' was increased to $172/af. OCWD further increased the RA to $205/af and further decreased the BPP
to 64%for 2005/06.
' In addition to the RA, groundwater production above the BPP is charged a fee called the Basin Equity
Assessment (BEA). The BEA is calculated by OCWD for each producer based on the producer's
production costs, such that the cost of the groundwater above the BPP is essentially the same as
' purchasing imported water through MWD. City groundwater production cost approximately $248/af
in 2004/05 (including the RA and energy but not including other well operation and maintenance
costs). The City currently purchases supplemental, treated, imported water from MWDOC for
' $472.50/af (exclusive of connection fees and readiness to serve charges). City groundwater
production cost will increase in 2005/06 as a result of the RA increasing from $172 of to$205/af.
The City's water supply has averaged 56% groundwater production and 44% imported water
purchases over the past eight years (1996/97 — 2003/04) as shown in Table 3-1 and on Figure 3-1.
However, the City participates in the In-Lieu or Cyclic Storage Program offered by OCWD and
MWD, when available. It is a groundwater replenishment program that refills the groundwater basin
' by avoiding pumping, and is usually offered in the lower demand period of October through April. In
the program, OCWD requests the City to leave a number of its wells turned off. The City then takes
replacement water through its imported water connections which is purchased by OCWD from MWD
' through MWDOC. OCWD purchases the water at a reduced rate, and then bills the City the amount it

would have had to pay for pumping energy and replenishment assessment if it had produced the water
' from its wells.

In-lieu imported water purchases have been approximately 13% of the total City water supply over the
past eight years, with imported water purchases not applicable to this program at approximately 31%
' as shown in Table 3-1 and on Figure 3-1. In-lieu water is regarded as groundwater production when
calculating a producer's BPP.
In addition to being less expensive, local groundwater is also considered a more reliable source of
' supply. Imported water must be conveyed to the City through long transmission pipelines that cross

' Chapter 3-Water Supply
active earthquake faults, which makes the imported water supply system susceptible to damage in a
seismic event. These transmission pipelines also operate at high pressures (outside of the City limits),
which make them susceptible to rupture from a pressure surge.
' 3.3 Water Quality
The Safe Drinking Water Act (SDWA), which was enacted in 1974, is the main federal law that
' regulates potable drinking water standards. Under SDWA, the U.S. Environmental Protection Agency
(EPA) sets standards for drinking water quality and oversees the states, localities, and water suppliers
who implement those standards.
' State potable water quality standards are set by the State of California Department of Health Services
(DHS). The potable water quality standards listed in the Title 22 California Code of Regulations
include primary and secondary maximum contaminant levels (MCLs). Primary MCLs are established
' for a number of organic and inorganic chemicals, trihalomethanes, and radioactivity as they relate to
public health. Secondary MCLs are established for chemicals or characteristics as they relate to taste,
odor, or appearance of drinking water. These State MCLs are the same or in some cases more stringent
' than the Federal MCLs.
The City's water supply consisting of groundwater and imported water consistently meets or exceeds
' all State and federal potable water quality standards. The City maintains a water-quality monitoring
program consistent with DHS requirements.
As a result of the high quality of the City's source water supplies, the only water treatment conducted
' by the City is disinfection and fluoridation. The City disinfects at each of its well sites through the
injection of gaseous chlorine (Clz) typically at a rate of about 1.0 milligram per liter (mg/1) residual.
The City receives imported water that has been disinfected by means of chloramination typically at a
rate of about 2.2 mg/1 residual.
The City has fluoridated its water supply to aid in the development of healthy teeth since 1972. The
' natural fluoride concentration of the groundwater ranges from 0.3 to 0.4 mg/l and the imported water
supply has a fluoride content of 0.2 mg/l. The City increases the fluoride concentration to between
0.70 to 1.30 mg/l via injection stations located at all wells and imported water connections.
t3.3.1 Proposed New Water Quality Rules and Standards
Arsenic
' A new federal water quality regulation will be a reduction in the MCL for arsenic, an inorganic
chemical, from 50 parts per billion (ppb) to 10 ppb. The revised MCL must be complied with
' beginning in January 2006. The average arsenic level in' the City's water supply has historically ranged
between "Not Detected" to 3 ppb and has averaged "Not Detected". Accordingly, treatment of City
supply sources to meet the stricter arsenic MCL is not anticipated.
' Groundwater Rule
EPA is proposing the Ground Water Rule (GWR), which specifies the appropriate use of disinfection
in groundwater and addresses other components of groundwater systems to protect against bacteria
and viruses in potable groundwater supplies. The requirements of the proposed GWR include State-
conducted system sanitary surveys and compliance monitoring for systems that disinfect to ensure that

' Chapter 3 -Water Supply
they reliably achieve 99.99% (4-log) inactivation or removal of viruses. The City currently disinfects
' at all of their well sites through the injection of gaseous chlorine.
Radon
' Radon is a naturally-occurring radioactive gas that may be found in indoor air and in drinking water.
Exposure to radon can increase the risk of getting cancer. Radon in soil under homes presents a greater
' risk than radon in drinking water. There is currently no MCL for radon in drinking water. EPA has
developed a proposed regulation to reduce radon in drinking water that includes a "Multimedia
Mitigation program"option to reduce radon in air.
' The proposed regulation offers two options:
• Option 1: States can choose to develop enhanced state-wide programs to address the health
risks from radon in indoor air known as Multimedia Mitigation (MMM) programs while
reducing radon levels in drinking water for individual water systems to 4,000 pCi/L or lower
(picoCuries per liter, a standard unit of radiation). EPA is encouraging states to adopt this
' option because it is the most cost-effective way to achieve the greatest radon risk reduction.
• Option 2: If a state chooses not to develop an MMM program, individual water systems in that
' state would be required to either reduce radon in their system's drinking water to 300 pCi/L or
develop individual local MMM programs and reduce levels in drinking water to 4000 pCi/L.
Water systems already at or below 300 pCi/L standard would not be required to treat their
water for radon.
' Radon in the City's water supply averaged approximately 395 pCi/L in 2002, 388 pCi/L in 2003, and
327 pCi/L in 2004. Radon treatment alternatives include aeration and treatment with granular
' activated carbon filters.
Staize 2 Disinfectant Byproduct Rule
' Chlorine and other.chemical disinfectants used by public water systems to control microbial pathogens
in drinking water interact with organic and inorganic materials in source water to form disinfection
' byproducts (DBP). Epidemiology and toxicology studies have shown a link.between disinfection
byproducts, specifically total trihalomethanes (THM) and haloacetic acids (HAA), and some forms of
cancer.
' EPA's Stage 1 Disinfectant Byproduct Rule (DBR) requires water systems to meet THM and HAA
MCLs of 80 ppb and 60 ppb, respectively. Compliance is determined by calculating the running
annual averages of samples from all monitoring locations across the system. TTHM and HAA5
averaged 17 and 6; 24 and 9; and 17 and 6; for the Huntington Beach water system in 2002,2003, and
2004, respectively. These values are well below the MCLs.
' Under the proposed Stage 2 DBR, systems will be required to conduct an evaluation of their
distribution system to identify the locations with high THM and HAA concentrations. This evaluation
could change the locations currently monitored. Also, levels of THM and HAA can vary significantly
from one point in a water distribution system to another. Under the proposed Stage 2 DBR,
compliance with the MCLs for THM and HAA will be calculated for each monitoring location in the
distribution system (locational running annual average), as opposed to the current less stringent
CITY OF HUNTINGTON BEACH TETRA TECH,INC.
' 2005 Water Master Plan and Financing Plan 3-4
' Chapter 3 -Water Supply
method of calculating running annual averages of samples from all monitoring locations across the
' system.
The Stage 2 DBR will be implemented in two phases. During Phase 1 of the implementation, the
' MCLs for THM and HAA will be 80 ppb and 60 ppb, respectively, based on running system-wide
annual averages (the current methodology) at the current monitoring sites. Additionally, locational
running system averages (sample site specific) of 120 ppb and 100 ppb for THM and HAA,
respectively, will be introduced. During Phase 2, the compliance sites will be changed based on the
system-wide evaluation for high DBP sites and the locational annual averages will be reduced to 80
ppb for THM and 60 ppb for HAA.
' 3.4 Groundwater Supply
The City and other OCWD member agencies are charged the RA for groundwater produced from the
' Orange County Groundwater Basin (groundwater basin) up to the BPP, and are charged an additional
BEA for groundwater produced over this percentage. The BPP is uniform for all members and is set
at 64% for 2005/06. The RA is set at.$205/af for 2005/06. In recent years the BPP has been
' decreased and the RA has been increased in consideration of lower groundwater levels. By decreasing
groundwater use and shifting the pumping in the basin inward away from the coast, OCWD hopes to
hold back seawater intrusion. The lower groundwater levels were caused by gradually increasing
' groundwater production from 1993/94 through 2002/03 and drought conditions from 1998/99.through
2002/03 that reduced the amount of local water available to refill the basin.
' 3.4.1 OCWD Projects
OCWD has on-going and proposed projects to protect,clean, and refill the groundwater basin.
' Talbert Seawater Intrusion Barrier
Since 1975, OCWD has operated a seawater barrier to keep seawater from mixing with and
' contaminating potable groundwater. Fountain Valley's Seawater Intrusion Barrier is a series of 28
injection wells running along Ellis Avenue from Euclid Street to Newland Street. A mixture of
wastewater purified at Water Factory 21 in Fountain Valley and deep well water is pumped to the
' wells and injected into the ground to create an underground dam that blocks seawater from entering
the groundwater basin.
OCWD has just completed a project to further protect the groundwater supply with an expansion of
' the seawater intrusion barrier. OCWD recently filed a report under the California Environmental
Quality Act (CEQA) as a first step toward a construction project to install piping in Ellis Avenue and
drill injection wells in the Southern California Edison property near Newland Street(Harper Park).
' Groundwater Replenishment System
' The Groundwater Replenishment System, which is scheduled to go on line in 2007, will divert highly
treated sanitary wastewater from the Orange County Sanitation District that is currently discharged
into the ocean, and treat it through advanced techniques, including microfiltration, reverse osmosis and
' ultraviolet disinfection and hydrogen peroxide. The treated water will then be injected into the
groundwater at strategic injection sites. The injected water will help fortify the seawater intrusion
barrier or will be percolated into deep aquifers, where it will eventually become part of the potable
groundwater supply. The treated water will exceed all federal and state drinking water standards. The

treated water will be near-distilled water that will improve the overall quality of the groundwater basin
iby lowering the mineral content.
3.4.2 City Groundwater Production
' The capacities of the City's ten active potable water wells are shown in Table 3-2. Well No. 1 is
scheduled to be re-drilled in 2006 and it is estimated that the capacity of this well will increase from
i 500 gpm to approximately 750 gpm when this work is completed. Well No. 12 is a new well that was
recently construction. The locations of the City's potable water wells are shown on Figure 3-2.

' consideration of several factors including groundwater level, water quality, and chlorine feed. The
City prolongs the life of the wells and associated supply equipment when operating at less than
capacity. The normal operating supplies for the City's wells are also shown in Table 3-2. Overall,
