4. PUBLIC HEARING:
GPA-92-02 Consideration of city-
initiated amendments to the Public
Facilities Element of the General Plan
implementing and supplementing the
approved County of San Diego Hazardous
Waste Management Plan.
A. BACKGROUND
1. On January 6, 1992, the City received written notification
from the Board of Supervisors that the County of San Diego
Hazardous Waste Management Plan (COHWMP) had been approved by
the State Department of Toxic Substances control. Pursuant to
provisions of State law under which the COHWMP was prepared
(AB 2948 (Tanner, 1986)), within 180 days of that notification
the city is required to take one of the following actions to
establish local hazardous waste management provisions
consistent with the COHWMP, in order to retain maximum local
control over hazardous waste management issues, including
facility siting:
incorporate the County plan, including any
refinements, by reference, into the city's General
or
local
Plan,
_ adopt an ordinance implementing the county plan, or
_ prepare our own Hazardous Waste Management Plan.
That l80 day period ends on July 4, 1992.
2. Staff has elected the first option as providing the City
appropriate control over local hazardous waste management
planning. As the existing Public Facilities Element of the
General Plan contained discussion and policies related to
hazardous waste, revisions have been made to those discussions
to incorporate the COHWMP by reference, and to establish those
more specific hazardous waste management provisions particular
to Chula vista, and designed to ensure public health and
safety, and environmental protection. The amended Public
Facilities Element is contained in Attachment A to this
report. For ease of review, those pages involving amendments
are colored, with deletions hatched out and additions
underlined.
3. The Environmental Review Coordinator has concluded that an
Addendum to the COHWMP Final EIR (dated July 10, 1989, Sch. #
87120222) may be prepared for the proposed General Plan
Planning commission
Agenda Item for the Meeting of June 24, 1992
Page 2
Amendment. This Addendum (see Attachment B) prepared under
EIR-92-03 evaluates the potential environmental impacts with
the city's adoption of the COHWMP.
B. RECOMMENDATIONS
1. Adopt a motion recommending that the city Council consider
EIR-92-03, Addendum to the County Hazardous Waste Management
Plan EIR, prior to taking action on the project.
2. Adopt a motion recommending that the city council approve the
proposed General Plan Amendment and direct staff to prepare
the necessary implementing ordinance(s).
C. DISCUSSION
l. The San Diego County Hazardous Waste Management Plan was
prepared pursuant to state Assembly Bill 2948 (Tanner, 1986).
This legislation, commonly referred to as the Tanner Act, sets
forth the framework for local implementation of changes in
federal and state laws governing the way hazardous wastes
should be managed. The Federal Resource Conservation and
Recovery Act (RCRA), the Hazardous and Solid Waste Amendments
of 1984, and State statutes enacted in 1985 and 1986 all
prohibit the land disposal of untreated hazardous waste after
May 1990. The result is a substantial increase in the need
for treatment and disposal capacity, and given the inherent
complexity in siting such facilities, a strong need to focus
on reducing the volume of wastes produced. Much of todays
consumer goods and other commodities are greatly dependent
upon products containing chemical substances, and/or requiring
the use of chemicals in their manufacture and packaging. In
order to sustain our standard of living and ensure economic
stability, safe and responsible management of hazardous wastes
in ways that protect the environment and human health and
safety is of extreme importance.
2. As required by the Tanner Act, the COHWMP establishes such
comprehensive provisions for the safe and effective management
of industrial, small business and household hazardous wastes
within the San Diego Region. It is predicated upon a
management hierarchy which focuses on the need to reduce the
volume of wastes produced requiring treatment, and prescribes
various planning, processing, siting and permitting
requirements to be applied in evaluating proposals for needed
treatment facilities to ensure the protection of public health
and safety, and the environment. It also contains
comprehensive background information on waste management, and
existing and projected waste generation and facility needs
within the Region. The COHWMP serves as the primary planning
planning Commission
Agenda Item for the Meeting of June 24, 1992
Page 3
document providing overall policy direction for the effective
management of lOOt of the Region's hazardous waste stream, and
is the guide for local decisions regarding hazardous waste
issues.
The COHWMP was prepared over a two year period by the County
of San Diego and SANDAG in cooperation with a 31 member
Advisory Committee containing representatives from each of the
Region's 18 jurisdictions. It has previously been reviewed
and approved by the city, both prior to its initial submittal
for State review in August 1989 (City Council Resolution No.
15266), and upon its revision as required by the State in June
1991 (City council Resolution No. l6179). Now that the city
has been notified of the state's final approval, we are
required by law to formally adopt the COHWMP as a policy and
decision making guide through the establishment of local
hazardous waste management policies and provisions consistent
with the COHWMP, in oder to maintain maximum local control
over hazardous waste management issues, including facility
siting.
3. While adoption of local provisions must be consistent with the
approved COHWMP, the city is not precluded from establishing
more specific or stringent planning requirements and siting
criteria than those of the COHWHP. Therefore, in addition to
incorporating the COHWMP by reference, the proposed amendments
to the Public Facilities Element have been designed to reflect
those more specific local conditions and concerns regarding
hazardous waste management and facility siting proposals in
ensuring the utmost protection of the health and welfare of
citizens, and environmental resources within Chula vista.
The nature of those refinements as reflected in the proposed
amendments are as follows:
a. strong local emphasis on pollution prevention and waste
minimization through source reduction, re-use and
recycling of industrial, small business and household
hazardous waste to lessen the need for new or expanded
hazardous waste facilities.
screening
hazardous
to ensure
processes for local businesses using
materials and generating hazardous wastes
commitments to waste minimization.
active promotion of recycling and alternative
technologies through the city's conservation
coordinator in cooperation with the county.
Planning commission

b. development of an overall strategy regarding equitable
facility siting responsibilities which recognizes the
ci ty' s waste management commi tments and existing
facilities in relation to those of other jurisdictions in
the Region in a "fair share" setting.
c. emphasis of the foremost protection of local public
health and safety, and the environment through the
refinement of locational, siting and permitting
requirements for considering hazardous waste facility
proposals.
the removal of certain industrial areas from the
"general areas" inventory of lands which are
appropriate for considering facility applications.
Those areas removed include Montgomery, Eastlake
and Rancho Del Rey Business Parks, and a portion of
the otay valley Rd. area.
requirements for preparation of a Health Risk
Assessment and any related technical studies at the
discretion of the city for all facility proposals
regardless of their type, size or proximity to
existing and future populations.
refinement of numerous siting criteria for 32
separate subject areas which must be satisfied for
a facility to be sited. The criteria are arranged
under the following eight objectives;
Protect the Residents of Chula vista
Ensure the structural stability of the Facility
Protect Surface Water Quality
Protect Groundwater Quality
Protect Air Quality
Protect Environmentally Sensitive Areas
Ensure Safe Transportation of Hazardous Waste
Protect Social and Economic Goals
Staff believes that incorporation of the above refinements
provide the city the level of discretion and control over
hazardous waste management issues within the city which will
ensure the protection of local residents, the environment, and
economic stability.
4. Effective application of the various policies and criteria of
the General Plan Amendment, requires the development of
specific implementation measures. Subsequent to approval of
these amendments, an implementing ordinance(s) shall be
prepared for consideration by the planning commission and city
Planning Commission

council, which will set forth all applicable procedural
requirements for evaluating facility applications, including
but not limited to, pre-application and application processes,
submittal requirements for environmental reviews, risk
assessments and conditional use permits, and local monitoring
and enforcement provisions.
Any additional revisions to the General Plan which may result
from these efforts, or which the Planning commission or city
council may desire, will be brought back concurrently with the
implementing ordinance(s), which are anticipated for
completion within the next two to three months.

1. INTRODUCTION
The publ i c faci 1 it i es el ement of the Chul a Vi sta General Pl an focuses on the
facilities and services that are controlled by the City through direct
administration or contractual agreement, and facilities provided as obligatory
services by other public agencies. In the case of hazardous waste treatment.
stor~~e and di~oosal. non-obliQatorv facilities orovided bv the orivate sector
and t necess rilv under the Citv's control throuQh direct administration or
contractual aQreement. are also addressed. Excluded are public facilities
that fall directly within the scope of other elements of the plan such as
ParKs and Recreation, Circulation and others.
2. GOALS AND OBJECTIVES
The general objective and goal of the City of Chula Vista, as it relates to
the infrastructure requirements of the general plan, is to promote an adequate
and efficient range of public facilities and services. This will be
accomplished by identifying Key issues that should be addressed by the Public
Facilities Element and establishing the goals and objectives in response to
each issue.
Issues are statements of either opportunities or problems the City will
encounter in providing adequate infrastructure requirements. Goals and
object i ves are statements of val ue regardi ng what should or shoul d not take
place during the course of the City's development. The issues, goals and
objectives which are appl icable to the water, wastewater, drainage and flood
control and sol id and hazardous waste facility requi rements are discussed in
this section.
GOAL 1. WATER FACILITY PLANNING
As in many other areas of Southern Cal ifornia, Chula Vista has experienced
significant growth over the past two decades. This growth has placed an
increased demand on the water distribution and supply facilities for the
area. Chula Vista is highly dependent on imported water supplies from the
Colorado Ri ver Bas i n and State Project Water from Northern Ca 11 forn1a. In
recent years, below average rainfall throughout Cal ifornia coupled with a
court decision reducing California's share of Colorado River Water, has
increased the importance of proper water management and conservation. It is
the goal of Chula Vista taKe actions, appropriate to its population and
resources, to control the growth in demand for water and promote water
conservation.
Objective 1. Promote water conservation through increased efficiency in
essential uses and use of low water demand landscaping.
Objective 2. Encourage, where safe and feasible, wastewater reclamation and
use of reclaimed water for irrigation and other uses.
Objective 3. Encourage suppliers to adopt a graduated rate structure
designed to encourage water conservation.
Objective 4. Actively participate in the agency planning for providing
adequate emergency storage and supply facil it ies ,for Chula Vista and
neighboring communities.

GOAL 2. WASTEWATER FACILITY PlANNING
Chula Vista relies on the City of San Diego Metropolitan (Metro) Sewage System
for treating and disposing of the wastewater generated within the general plan
area. The City of San Diego has been mandated by the Environmental Protection
Agency to upgrade the Metro system to secondary treatment levels. This
mandate, coupled with the increased demand on Metro, will result in
significant expansion to the existing system of which Chula Vista is part. It
is the goal of the City to participate in the regional decision-making process
regarding this expansion and to control the growth in demand for wastewater
treatment within the general plan area.
Objective 5. Continually monitor wastewater flows and anticipate future
wastewater increases that may result from changes in the adopted land use.
Objective 6. Promote low wastewater generating development where appropriate.
Objective 7. Actively participate in the Metro expansion planning process,
and where appropriate, evaluate reasonable alternatives to eliminating Chula
Vista's dependence on Metro.
Objective 8. Assure that new development meets or exceeds a standard of high
quality in wastewater facility planning and design and that existing
downstream facilities are not adversely impacted by the addition of new
development upstream.
Objective 9. Resist the addition of permanent new pump stations where
gravity flow is at all possible.
GOAL 3. DRAINAGE AND flOOD CONTROL FACILITY PlANNING
As growth occurs in the future, the proportional amount of rainfall runoff
from each drainage area will increase. As a result, existing drainage and
flood control facilities downstream will begin to experience higher flow rates
than they have been experiencing or were designed for. It is the goal of the
City to properly regulate design of future facilities such that the
effectiveness of the existing drainage facilities are not degraded.
Objective 10. Required development of on-site detention of storm water flows
such that where practical, existing downstream structures will not be
overloaded.
Objective 11. Assure that new development incorporates a high degree of
sediment control as part of their project.
Objective 12. Preserve the existing drainage structures in Central Chula
Vista where possible to minimize the disruption to the public and the
requirement for additional space for larger facilities.

GOAL 4. SOLID ~P/~~I!~ WASTE CONTROL PLANNING
The production of solid wastes in San Diego County, including Chula Vista, has
steadily increased on a per capita basis at about 10 percent per year since
1982. '/>'v,1l1:lli 1/ /titttv'rJr/i/'Il ~ I NpMt/./o.bN I~j.j.lltyir; I MIo'\.1W~ I /I+'1M' It'M
~~~t~p~/~llp~~/~~tt~At/~/~~~~pr;rr;gf/ If this trend continues as more
development occurs, and based on the availability of suitable disposal sites,
Chula Vista could experience a solid JPr!I/liJ,t..atMM waste disposal problem.
This could mean at minimum a significant cost increase for transporting
materials great distances to available disposal sites and the possibility of
increasing the number of waste transfer sites within the City. While control
and siting of disposal sites falls under the jurisdiction of agencies other
than Chula Vista, including the County of San Diego and State of California,
the City has the ability to control waste production within its general plan
area. It is the goal of Chul a Vi sta to take action appropri ate to its
population and resources, to promote reductions in solid j.~~II~j.tj.t~p~j.
waste production and plan for adequate disposal.
Objective 13. Promote recycling of any material which has a reusable nature.
Provide public facilities to handle recycling of materials such as paper,
glass and others.
Objective 14. Support waste reduction legislation.

3. INVENTORY OF EXISTING PUBLIC FACILITIES
The public utilities and service system is one of the most important
considerations in urban development. Urban development and growth is
dependent upon the availability of public utilities and services. Conversely,
expansion of these is dependent upon thorough planning which in turn is an
extension of appropriate and well-reasoned land use analysis and proposal. .
The facilities and networks which make up the public works "infrastructure"
are generally considered as the foundat ions upon whi ch activity areas are
facilitated and maintained. In .the case of Chula Vista, the infrastructure
may be one of the primary criteria for detennining future growth of activity
areas.
The infrastructure addressed in this element consists of the following
facilities:
Water
Wastewater
Drainage and Flood Control
Solid and Hazardous Waste Control
Generally, the City of Chul a Vi sta is bei ng adequately served by its publi c
works infrastructure. Certain facilities, however, are in need of improvement
and upgrading. The following sections discussed in greater detail each of the
infrastructure systems and the agencies controlling them.
3.1 WATER FACILITIES INVENTORY
"
The City of Chula Vista's general plan area is provided water service
primarily by two major water agencies. These will be discussed below and are
shown on Figure 3-1.
Sweetwater Authority
Central Chula Vista is served by the Sweetwater Authority whose service area
within the City is bounded by Interstate 805 and Sweetwater Reservoir to the
east, San Di ego By to the west, the Otay Ri ver Vall ey to the south and SR 54
Bonita Road to the north. Approximately sixty percent of Sweetwater's system
is supplied by gravity from the Sweetwater Filtration Plant. The remainder of
the system is comprised of pumped pressure zones at the higher elevations.
Source supply for the City's portion of the system is largely from surface
water runoff and collection at Sweetwater Reservoir augmented by the San Diego
County Water Authority aqueduct system when necessary. Transmission and
distribution pipelines ranging in size from 6 inches to 42 inches, deliver
water to Chula Vista with a normal operating pressure range of 40 to 90 pounds
per square inch (psi). Daily and seasonal peak flow requirements, including
fire flows, are offset by ope rat iona 1 storage reservoi rs located throughout
the City. Total operational storage for Sweetwater is approximately 38
millions gallons with an average daily demand of about 24 million gallons per
day.
WPC 0324P
3-6
Otay Water District
The easterly portion of the general plan area is served by the Otay Water
District. Otay refers to this area as the Central Area which encompasses
three Improvement Districts including 1.0. No.5; I.D. No. 10; and I.D. No.
22. Improvement Di stricts are defi ned as areas whi ch are assessed fees in
relation to the benefit received for constructing water or sewer facilities
for that area. These districts were formed on the following dates:
I.D. No.5, November 28, 1960 by Resolution No. 123
1.0. No. 10, February 11, 1963 by Resolution No. 265
1.0. No. 22, July 3, 1972 by Resolution No. 986
This portion of the general plan area is bounded by Interstate 805 to the
west, the Otay River Valley to the south the Lower Otay Reservoir to the east
and the area known as Bonita to the north. Approximately 39 percent of this
area is served by gravity while the remainder requires pumping. The system is
comprised of five pressure zones (service areas), two water booster pump
stations, six reservoirs and two connections to the San Diego County Water
Authority filtered water aqueduct system. The aqueduct system suppl ied by
Colorado River Water and State Project Water provides the only supply source
to this area. Pipelines range in size from 6 inches to 30 inches and current
total storage volume is approximately 32 million gallons. The average daily
demand for the system is about 4.5 million gallons per day.

3.2 WASTEWATER FACILITIES INVENTORY
As a member of the City of San Diego Metropolitan Sewage System, Chula Vista
currently has contracted for capaci ty rights equal i ng 17.1 mgd average daily
flow. Including the 2.0 mgd metro capacity rights that were acquired when
Chul a Vi sta over the ope rat i on of the Montgomery Sanitation Di stri ct bri ngs
the total contract capacity to 19.1 mgd for Chula Vista.
The City of Chula Vista operates and maintains its own sanitary sewer system.
This system consists of approximately 270 miles of sewers ranging in size from
6 inches to 36 inches, 10 raw sewage pump stations and three independent
metered connections to the City of San Diego Metropolitan Sewer System
(Metro). Figure 3-2 illustrates the major components of the existing
wastewater system.
The northern portion of the City gravity flows into the Spring Valley
Interceptor which is generally located in Sweetwater Road. This line is owned
and operated by the County of San Diego. Thi s 1 i ne is owned and operated by
the County of San Diego, which leases 11.4 million gallons per day (mgd) to
Chula Vista. Presently, the City contributes 1.4 mgd to this line, which
terminates at a connection to Metro near Sea Vale Street.
Central Chul a Vi sta transports its wastewater fl ows to Metro via two major
trunk sewers. The first major line being the "G" Street trunk sewer, which
receives tributary flows from the area bounded by "D" Street south to "H"
Street. This trunk sewer terminates at a metered connection to Metro located
off "G" Street just west of Bay Boulevard. Existing wastewater flows in this
line represent approximately 2.6 mgd. The second trunk sewer serving Central
Chula Vista from "H" Street south to Naples Street is located in "J" Street
and Telegraph Canyon Road. Th is 1 i ne begi ns in the east on Otay Lakes Road
near EastLake Drive and terminates at a metered connection to Metro located at
the end of "J" Street west of Bay Boulevard. This trunk sewer currently
transports 3.9 mgd of Chula Vista wastewater flows to Metro.
The southern port i on of Chul a Vi sta is served by the Ma i n Street and Fai vre
Street trunk sewers. These lines generally parallel each other beginning on
the easterly side of the Interstate 805, and ending at a single connection to
Metro at the end of Faivre Street. The two lines join in Industrial Boulevard
pri or to maki ng the Metro connect i on. Presently, 4.1 mgd worth of flow is
being metered at this last connection. The total Chula Vista wastewater flow
into Metro is therefore 12.0 mgd at this time.
3.3 DRAINAGE AND FLOOD CONTROL FACILITIES INVENTORY
The City of Chula Vista operates and maintains its own drainage and flood
control facilities. This system, as shown in Figure 3-3, is made up of
improved and unimproved flood control channel s, storm drains, bridge
crossings, detention basins and various other facilities. These facilities
range in age from recently constructed to in excess of 30 years old. In
general, the existing structures are in good condition and free of debris and

sediment. The single, largest maintenance problem the City has experienced
over the years has been maintaining the unimproved channels in I clear
condition, free of vegetation and other debris such as shopping carts.
Obstructions of this nature have historically caused stream blockage and
remote flooding if left unattended.
As in all systems of this nature, the existing drainage and flood control
facilities have their limitations. Development of the system by the City has
been guided, over the years, by the use of numerous studies and reports
including primarily the 1964 drainage master plan report prepared by Lawrence,
Fogg, Florer and Smith. The most significant hydraulic problem with drainage
in Chula Vista is the downstream portions of the numerous natural drainage
channels which have been developed over the years. Initially, runoff was
directed into the natural, or possibly improved channels, or into storm drain
trunk line. As the upstream portions of the drainage areas developed, the
load on the downstream system increased. In some instances this has resulted
in occasional downstream flooding because the existing systems Ire not able to
convey the runoff adequately. The problems and constraints of the major
drainage courses are described briefly.
Palm Canyon is located in southeast Chula Vista and drains to the Otay
River. The upstream portion has been lined through the developed area and is
in good condition. The downstream section, with outfall to Otay River, is
heavily vegetated and there are significant flow constrictions at several
culverts.
Poggi Canyon also is located in southeast Chula Vista and drains to Otay
River. The upstream portion has been lined through the developed areas. The
downstream portion and outfall to Otay River are heavily covered by brush.
Sediment deposition in a box culvert at Otay Valley Road if left unattended
will reduce the effective hydraul ic capacity of this facil ity. There is
potential for substantially increased flows in this basin due to the
availability of undeveloped land in the upper canyon.
Telegraph Canyon is located in Central Chula Vista and drains to San Diego
Bay. The portion of channel above Hilltop Drive has been lined through the
developed area and is in good ctmdition. Sections of the downstream portion
below Hilltop Avenue appear undersized as evidenced by recent high waters
through the channel. There is a potential for substantially increased flows
in this channel due to new development in the upper canyon.
Central Area Basin is located in north Central Chula Vista and drains to San
Diego Bay. The channel has a few areas of 1 ining but nothing significant.
This area is not subject to substantial new development so runoff should not
be increased greatly in the future. However, this channel appears too small
to convey 100-year storm flows.
Lower Sweetwater is located in norther Chula Vista and drains to San Diego
Bay. Thi s is an area that wi 11 be channel i zed as part of the Corps of
Engineers flood control program. This area has historically experienced
flooding during significant rainfall, however, the Corps of Engineers project
should alleviate this problem.
WPC 0324P
3-12
Upper Bonita Long Canyon is located in northeast Chul a Vi sta and drai ns to
Sweetwater River. The channel has been lined in the upstream areas and
appears adequate for existing development. There is a potential for
substantially increased runoff due to the availability of land in the upper
canyon. The lower canyon development has encroached into the flood plain, Ind
increased runoff from developing areas in upper canyon may cause future
problems.
3.4 SOLID ",iJ//~ WASTE COLLECTION AND DISPOSAL FACILITIES
INVENTORY
~~~I~I~~7/~~71~~~~t~
Control of the solid ~/'#t~;#r# waste collection and disposal for the
general plan area fall under several jurisdictions. Regional planning and
management for San Di ego County's sol id wastes are admi ni stered by the San
Diego County Solid Waste Division of the Department of Public Works. This
agency is responsible for revising and updating the "Regional Solid Waste
Management Plan" (RSWMP) which reviews current solid waste collection and
di sposal practices, predi cts future waste gene rat i on trends and reviews the
possible means for accommodating future collection and disposal needs. This
document is the major planning tool for the County and includes solid waste
planning for all of the cities within the County.
Coll ect i on and di sposa 1 of sol id wastes are the respons i bil ity of each city
for its residents. The City of Chula Vista and the communities in the sphere
of influence contract private coll ect ion agencies to assume collect ion and
disposal responsibilities for their residents. The following collection
agencies services the sphere of influence at present:
Chula Vista Sanitary Service
American Trash Service
Jamul Services
EDCO Disposal Corporation
Chula Vista Sanitary Service collects municipal refuse from Central Chula
Vista, Bayfront, Montgomery/Otay, Telegraph Canyon/Lakes, Sunnyside and Bonita
within the planning area. This agency as a 17-year contract with the City of
Chula Vi sta and has the abil ity to expand thei r operation to meet the long
range needs of Chula Vista area.
American Trash Service provides collection service for the South Bay area.
Within the General Plan Area, American Trash Service collects municipal refuse
from the Bonita community. This agency also services the communities of
Sweetwater, Dulzura, Jamul, Spring Valley, and Casa de Oro.
\ Jamul Services collects wastes in the Bonita, Jamul, Casa de Ora, and Dulzura
areas.
EDCO Disposal Corporation also provides collection service for the Bonita
community.
WPC 0324P

For waste disposal, there are currently nine landfills in San Diego County.
These are shown in Table 3-1. Figure 3-4 depicts the existing solid ~I!~
~~t~t~p~~ waste disposal sites within the general plan Irea. Wastes
collected in the Chula Vista area (approximately 131,000 tons per year in
1985) are disposed of at the Otay Landfill. This facility is located north of
Otay Valley Road on the south side of Chula Vista and serves the Cities of
Chula Vista, Coronado, Imperial Beach, National City, Ind San Diego. Otay
Landfill was opened in February of 1966, and the expected worst-case closure
date is 1999. The worst-case scenario, according to the Regional Solid Waste
Management Plan, assumes that no new facilities are added to the region's
existing disposal system, and average annual waste generation increases by 5%
per year. Under this plan, Otay Landfill will be the last landfilling the
region to close.
Specific data pertaining to the Otay Landfill design are as follows:
Landfill size - 294 acres
Tons received per day (1986) - 1,380 tons/day
Remaining volume - 25,800,000 CY or 15,480,000 tons
In-place density of compacted trash - 1,200 lbs/CY minimum
Property size - 515.64 acres
Cut slope - 1:1 or 1.5:1
Fill slope - 3:1
Existing disposal operations at each of the County's landfills are reviewed
continually by the County and the City of San Diego to determine if operation
or des ign changes woul d allow extended use of the site. Such changes may
include height and slope modifications for active work areas, increased
in-place density of compacted trash and acquisition of additional acreage to
expand existing site capacity. There are at present no plans for expansion of
the Otay Landfill due to public resistance to additional landfilling in the
area.

Collection, transporting, treatment. and disposal of hazardous wastes are the
respons i bil i ty of the generators of such wastes. Hazardous waste generators
incur both financial and envi ronmental 1 iabil ity due to coll ect ion,
transporting, treatment and disposal of hazardous wastes generated.
Therefore, hazardous waste generators must select transporters and

3.' i SECONDARY SCHOOLS INVENTORY
Secondary school facilities within the City of Chula Vista are provided by the
Sweetwater Union High School District. the district operates senior high
schools, junior/middle high schools, adult education schools and a continuing
education school. Ten of these facilities are located in the City.
The California Basic Education Data System (CBEDS) enrollment prepared for the
1988-89 school year showed that the district has an enrollment of 26,845. The
schools in operation for the 1988-89 year have been designed and constructed
to house a total of 22,648 students. To mitigate overcrowded conditions, the
district houses students in temporary classrooms such as trailers and
relocatable structures.
Through the use of previous CBEDS enrollments and demographic analysis, the
district projects an enrollment in excess of 35,377 by the year 1993. Based
on these projections, the district will require I minimum of seven new
secondary facilities to meet the increased demand.
A new senior high school will be located in the EastLake Planned Community.
It is anticipated that this school will house 2,400 students. Additionally, a
middle school site is anticipated to be located within the Rancho Del Rey
Phase III development. That school should house approximately 1,400 students.
3._ Z ELEMENTARY SCHOOLS INVENTORY
Elementary school facilities within the City of Chula Vista are provided by
the Chula Vista City School District. The district is currently operating 30
schools. Ten of these facilities are on year-round schedules with the
remainder on the traditional school calendar.
CBEDS enrollment prepared for the 1988-89 school year showed District
enrollment at 16,179. Existing schools have been designed to house a total of
600 students each. To mitigate overcrowded conditions, the district currently
utilizes relocatable classrooms.
Through the use of previous CBEDS enrollments and demographic analysis, an
enrollment in excess of 20,800 is projected by the year 1985. Based on these
projections, the district will require a minimum of seven new elementary
facilities to meet the increased demand.
A new elementary school will be located in the EastLake Planned Community. It
is anticipated that this school will house 650 students and be in operation in
1989. A second new school will be located on the Windrose Way near the Terra
Nova Center. Additionally, a school site located within the Sunbow
development is planned.

3.7 ~ LIBRARY INVENTORY
The City of Chula Vista currently operates the Civic Center Public Library on
"F" Street in Central Chula Vista and two neighborhood branch libraries in the
Montgomery area. The City has adopted a standard of 0.5 to 0.7 square feet of
library space per capita.
4. PUBLIC FACILITIES PLAN
The required public facilities necessary to provide adequate service for the
proposed land use is discussed in this section. Recommended improvements
presented herein were the results of numerous studies and reports prepared by
the control agencies and outside consultants. These facilities would require
implementation as development occurs in order to guarantee that he high
qua li ty of publ ic ut 11 it i es and servi ces cont i nues to be the standard that
Chula Vista enjoys today.
The infrastructure addressed in this element consists of the following
facilities:
Water
Wastewater
Drainage and Flood Control
Solid and Hazardous Waste Control
4.1 WATER DISTRIBUTION NETWORK
The recommended future system improvements that will be required in order to
accommodate the planned growth for the general plan area are shown in Figure
3-~ ~ and are discussed below.
Sweetwater Authority
In 1985, a Water Master Plan Update was prepared which reviewed the adequacy
of the total system, including Chula Vista, at buildout conditions. This
report used the then current Chul a Vi sta General Pl an for plott i ng various
land use categories for the service area. Based on this data, in conjunction
with historic water usage data per land use category, ultimate water demands
were projected and hydraul i c analyses were performed. The report concl uded
the following:
(1) The supply facilities will require expansion to meet future
requirements. The supply facil ities are defined as the water treatment
plant, the raw water pump station to supply the treatment plant, the
aqueduct service connection (filtered water) and the local wells.
Recommendations include treatment plant expansion to 45.4 mgd (30 mgd
currently) and a connection of the Water Authority's raw water aqueduct
system to Sweetwater Reservoir for off-peak storage.

(2) A comprehensive study needs to be initiated to review the long-term water
supply of the Sweetwater Authority.
(3) The existing water transmission mains will need bolstering for buildout
condition. Due to the lack of interconnecting pipelines between National
City and Chula Vista, Chula Vista is dependent on a single 36-inch
pi pel i ne under the I -805 freeway for supply. Shoul d 1 i ne fail, stored
water in Chula Vista would soon be expended and supply curtailed. The
Authority is in the process of implementing a series of interconnections
which will help to alleviate this problem.
(4) Approximately 63 percent of the required ultimate storage volume is
presently in place. An additional 18 millions gallons of storage will
need constructing prior to buildout.
(5) Numerous pump station expansions will be required in order to meet future
system requirements.

of implementing a runoff protection system for the reservoir.
(8) The ongoing cast iron water main replacement program should be continued
and the old steel water mains, which are approaching their expected life
span, should be added to the program.
It was concluded by the Water Master Pl an Update that future master pl an
updates should be conducted at five-year intervals or whenever land use
designations are modified.
Otay Water District
In 1987, Otay Water District prepared the Central Area Water Master Plan
Update which evaluated the system requirements at buildout conditions.
Limi ted land use data was ava i 1 ab 1 e for the majority of the service area.
However, conservative land use assumptions were used in conjunction with
specific plan development proposals for definitive projects such as [1 Rancho
del Rey and EastLake as the bas i s for future water demand project ions. The
land use data used in that report differs from the general plan designations
particularly in the easterly and southerly areas of the service area. The
system evaluation prepared by an outside consultant, subsequent to the Otay
report, used the general plan land use information and resulted in conclusions
and recommendat ions very simil ar to the Otay report. The foll owi ngpresents
the required future system improvements based on the previous analyses:
(1) The projected ultimate average daily water demand for the general plan
service area within the Otay Water District is 45.5 mgd.
WPC 0324P
3-23
(2) The water supply connections to the SDCWA aqueduct system should be
adequate for ultimate conditions although they will require further
analysis at a later date as water demands on the aqueduct system increase.
(3) Numerous water transmission and distribution pipelines will be required
in the future to provide adequate service.
These generally fall into two categories including: a) paralleling
existing lines, and b) installing new lines into areas that previously
had none.
(4) Approximately 70 percent of the required operational storage is presently
in place. An additional 14 million gallons of storage will require
construction prior to buildout.
(5) The service area is seriously deficient of emergency storage in the event
of an aqueduct failure. Approximately 163 million gallons of storage
will require construction in the future to accommodate anticipated
growth. The District is currently pursuing the first phase of this
objective.
(6) The two existing pump stations will require expansion in the future. In
addition, a new pump station will need to be built in the highest
pressure zone to service the upper elevations.
(7) The area within the Otay Ranch, east of Medical Center Drive, north of
the Otay Ri ver, west of Lower Otay Reservoi r and south of Tel egraph
Canyon Road should be served by separate facilities as determined at the
time development plans are proposed.
(8) A comprehensive study needs to be undertaken to review the long term
water supply and storage a 1 tern at i ves for the general plan area and the
San Diego County as a whole.
4.2 WASTEWATER COLLECTION AND DISPOSAL SYSTEM
In 1987, the City retained an outside consultant to evaluate the adequacy of
the existing wastewater system for the year 2005 and buildout conditions. The
proposed land use information and population densities contained in the
genera 1 plan were used to est imate future wastewater flows for the city.
Based on these flows, each of the major wastewater facil ities were examined
for deficiencies. In general, the study concluded that a major modification
to the existing system was not required at this time. However, the results
did indicate that certain additions and improvements to the system would b
necessary to accommodate the projected future sewage flows. The recommended
major facility improvements are shown on Figure 3-6 and are reviewed below.
WPC 0324P
3-24
Based on that'study, the average daily wastewater flow at buildout conditions
is estimated to be 29.6 mgd. For the year 2005, the projected average daily
wastewater flow is approximately 25.0 mgd. The following presents the
concl us ions and recommend at ions of the facil ity analyses based on these fl ow
rates:
(1) Numerous interceptor and trunk sewer improvements will be required in the
future to provide adequate service. The improvements generally fall into
two categories including: a) paralleling or replacing existing sewers, or
b) installing new lines into areas that previously had none.
The Central Chula Vista and Bayfront planning areas will require the
least amount of new 1 ines. The exception in this area would be the
southerly portion of the main Street and Faivre Trunk Sewers which will
require almost complete paralleling to accommodate future flows. This is
largely the result of having to provide transmission capacity for flows
generated in the Eastern Territories planning areas of Salt Creek, Wolf
Canyon and Poggi Canyon.
The Sweetwater planning area will require new sewers in the areas of
Proctor Valley and Wild Mans Canyon. The existing sewers east of
Interstate 805 generally appear to have adequate capacity for future
growth.
The Eastern Territories planning area will require the highest amount of
improvements largely resulting from the predominantly undeveloped nature
of the area. The majority of the recommended sewers in this are would be .
categorized as new lines for service areas that previously had none.
Dra i nage bas i ns to be improved i ncl ude Telegraph Canyon, Poggi Canyon,
Wolf Canyon, Salt Creek and the Otay Valley Area,
Several pump stations will require expansion prior to ultimate flow
conditions. In addition, it is likely that new temporary pump stations
will be constructed by developers in Eastern Territories planning area as
an interim measure for providing wastewater service to areas that
currently have no sewer system available. These temporary pump stations
shoul d be avoi ded when reasonably feas i bl e and shoul d be taken out of
service as quickly as gravity service becomes available to the general
area.

Ground water or storm water infiltration to the sewer system was not seen
as being a significant problem during the study period. However, the
winter of 1987 was below average in rainfall (11.6 inches as compared to
the eleven year average of 16.0 inches) and as such the results were
considered non-conclusive. Infiltration should be further analyzed in
subsequent studies during periods of normal or above normal rainfall
conditions to properly evaluate this potential. The low lying .reas of
the Sweetwater River Valley and Otay River Valley should particularly
receive close scrutiny.
WPC 0324P
3-25
(4) The City of Chula Vista has adequate capacity rights in the City of San
Diego Metro Sewer System to accommodate future growth. With a present
total flow to Metro of about 12.0 mgd and contract capacity of 19.1 mgd,
7.1 mgd is currently available for future development. However, Chula
Vista will require additional treatment capacity in order to Iccommodate
the ultimate buildout flow rate of 29.6 mgd.
The City of San Diego's Metro Sewer System is currently undergoing major
changes. The Environmental Protection Agency (EPA) has mandated that San
Diego convert their existing advanced primary treatment facility It Point
Lorna to secondary treatment. The net effect of this conversion is a
significant reduction in that plant's treatment capacity. With that
reduction and without other system changes, it is likely that San Diego
would not be handl e thei r contract flow rates from the member agenci es
including Chula Vista.
With this in mind, San Diego is in the planning process of upgrading the
overall Metro System which includes interceptors, pump stations and new
treatment plants. Chula Vista is an active member of this planning
process to guarantee that their best interests are being addressed.
Chula Vista has several options available to them for obtaining the
necessary future treatment capacity. They can continue to contract with
San Diego for capacity in metro, as they have in the recent past,
including increasing the contract capacity to accommodate the anticipated
future flows. The required Metro upgrades will come out of the planning
process are likely to be quite expensive. These costs will be passed on,
in part, to the member agencies which will increase the cost of treatment
to Chula Vista. Although no definitive numbers are available at this
time, it is thought that the cost San Diego would have to charge member
agencies for treatment could be between three to four times as great as
it is now.
Another option available to Chula Vista for obtaining the required
treatment capacity woul d be to construct thei r own treatment facil ity.
Although this alternative would have many obstacles in its way prior to
being implemented such as environmental considerations, land
availability, and general acceptance by the Chula Vista citizenry, it may
prove to be the most cost effective method of wastewater treatment and
disposal available to Chula Vista.
Still another available alternative would be a blend of both above
alternatives where Chula Vista would treat a portion of their wastewater
and divert the other part to Metro. Due to the uncertainty with respect
to the outcome of the Metro planning process, no reasonable decision can
be made at this time for directing Chula Vista's future preferred method
of treatment and disposal. This will be evaluated in greater detail in
an upcoming study presently authorized by the City.
WPC 0324P
3-26
(5) Reclamation should be reviewed in significant detail during the upcoming
study already authorized by the City. Although reclamation did not
appear to be cost effective during the most recent study, this conclusion
could be significantly affected by the outcome of the ongoing Metro
planning process.
If Chula Vista were to construct their own treatment plant or the City of
San Diego's new plant were to be located in closer proximity to Chula
Vista, the cost to provide reclamation facilities would be reduced.
Presently there appears to be about 0.35 mgd worth of demand for
reclaimed water within Chula Vista including greenbelt areas, freeway
landscaping and others. At ultimate this demand could be in excess of
1.0 mgd for for similar areas in newly developed portions of the general
plan area.
Conversely, if the use of reclaimed water was mandated by the City for
developments that could use it in an effort to lower the drinking water
demand, reclamation would not have to be completely cost effective to be
implemented. With the scarcity of water in Southern California, many
agencies are approaching reclamation from this standpoint. Chula Vista
is currently reviewing their reclamation opportunities and long range
planning.
4.3 DRAINAGE AND FLOOD CONTROL SYSTEM
In 1987, the City retained an outside consultant to evaluate the adequacy of
the existing drainage and flood control facilities at the General Plan
buildout conditions. The proposed land use information contained in the
General Plan was used to estimate future runoff volumes based on the 100-year
flood conditions. Based on these estimates, each of the major basin and
sub-basin drainage and flood control facilities were examined for
deficiencies. The level of effort expended in these analyses was not intended
to produce a comprehensive master plan, but to provide the initial studies
leading into a detailed master plan which Chula Vista has subsequently
authorized. The results of the initial study were sufficiently detailed to
provide specific proposed improvements as to the required hydraul ic
capacities, facility sizing and location and overall system configuration.
In general, the study concluded that a major modification to the existing
system configuration was not required. However, the results did indicate that
certain additions and improvements to the system would be necessary to
accommodate the 100-year flood conditions (shown in Figure 3-7). The proposed
improvements fall into two general categories including: 1) drainage and flood
control facil ity design criteria for use in guiding developer improvements,
and 2) specific basin improvements. The proposed design criteria and overall
system philosophy included the following:
(1)
Hydrology. The City should use a 100-year return frequency storm as a
basis of design. This is because the 100-year event is the accepted
standard for most municipalities for new development, the Federal
Emergency Management Agency, the California Coastal Commission, the
County of San Diego and most other State and Federal agencies.

(2) Sedillent Control and Grading. The City of Chula Vista has no standard
for sediment control. Consideration should be given to instituting
requirements for sediment control, especially since Chula Vista is
experiencing a significant amount of new development. Much of this
development is taking place in the upper canyon areas. These areas have
a high potential for large volumes of sediment. If there is no control
over the sediment, it is 1 i kely that probl ems will result in the lower
canyon areas as the sediment falls out and reduced cross-sectional areas
of culverts and channels.
(3) Detention Basins. Chula Vista is somewhat constrained by the existing
storm drainage facilities in the lower canyons and in the metropolitan
area. Some of these facilities were adequate for the initial development
phase, but as the upstream areas of the drainage basins have developed
there has been an increased load on the facilities. Because of the cost
and difficulty in increasing the capacity of the existing drainage
facll it i es, use of detention bas i ns as an a 1 ternat i ve means for flood
control should be considered. This should be determined on a case by
case basis. These detention basins can be constructed within the newly
devel opi ng areas and serve to detai n the runoff peaks long enough to
reduce the load on the downstream channels and storm drains.
(4) Hydraulics. The existing City criteria establishes minimum criteria
for both open channels and closed conduits. This criteria is consistent
wi th s imil ar requi rements throughout San Di ego County and so no changes
are proposed.
The following presents the proposed general drainage and flood control
improvements for the thirteen basins within the Chula Vista General Plan Area:
(5)
Central Area and Judson Basins. For basins with peak storm flows
approximately equal to those in the Fogg Report, no new ri!commendations
are made. Recommendat ions i ncl uded in the Fogg Report are cons i dered
still valid, especially for the Central area and Judson basins. This
i ncl udes channell i ni ng, cul vert i nsta 11 at ion and other general
improvements. '
(6)
Telegraph and Poggi Canyon Basins. These two basins will experience
the highest level of new development based on general plan. Both canyons
have severely 1 imited downstream capac i ties and will requi re s igni fi cant
improvements. For the most part, the downstream capacities of the
canyons are limited by the culverts and to a lesser, but still
significant extent, channel conditions. The options considered in the
improvement of the channel conditions were cleaning and maintaining the
natural channels, lining the channels with rock riprap or lining the
channels with concrete. The proposed channel improvements for this basin
were a combination of all three.

The options used for increasing culvert capacity included larger box
culverts and bridge structures. The bridge structure resulted in a more
cost effective solution for increasing the capacity at crossing
structures.
(7) Salt Creek Basin. Salt Creek Basin and Use development is proposed to
occur around the perimeter of the basin, with a large open area in the
center. This open space would incorporate the existing drainage path of
the Salt Creek Basin. The proposed improvements for this basin include
requiring the developers to detain excess flows so that the peak runoff
and velocities do not exceed existing conditions. This would allow the
exi st i ng , natural channel to remain unchanged. Mi scell aneous cul verts
and channel outlets would be required.
(8) All Remaining Basins. For remaining basins including Palm Road Basin,
Sunnyside Basin, Wolf Canyon Basin, Rice Canyon Basin, Glenn Abbey Basin,
Otay Lakes Road Basin, Long Canyon Basin and Harborside Basin, proposed
improvements included detention basins, culverts, bridge structures,
grade control structures and lined channels.
The City should prepare a comprehensive master plan to assist Chula Vista in
guiding the orderly and cost effective development of overall system up to the
year 2005 and beyond. Chula Vista is currently proceeding with this
recommend a ti on.
4.4 SOLID ~~/~~P~~ WASTE COLLECTION AND DISPOSAL SYSTEM
In 1987, Chula Vista retained an outside consultant to evaluate the solid
~4~/MJNM/JI> waste control requirements for the general plan area. Future
waste projections for the planning area were developed based on the general
plan land use information and appropriate waste generation factors. The
results indicated that Chula Vista's needs are being well planned for although
there exi sts a few long range shortcomi ngs. The concl us ions and
recommendations of that study are presented below.
Solid waste collection by the private agencies is currently being handled
satisfactorily. Each company has the ability and inclination to expand their
operations to meet the solid waste needs of the general plan area at 200S or
at buildout. It is estimated that in excess of 400,000 tons per year of solid
waste could be generated within the planning area by the year 200S. Expansion
of these operations will impact the roads and highways within the planning
area which is discussed in the Circulation Element of the general plan.
Solid waste disposal by the County of San Diego for the general plan area
presents no immediate problem. However, long, range solid waste control
planning for Chula Vista and the overall County is less defined. The Regional
Solid Waste Management Plan (RSWMP) was recently revised (1986) ,and the
revised version evaluates seven waste generation/disposal scenarios. The
worst-case scenario ("Do Nothing" alternative) indicated that there will be no
landfills remaining in San Diego County after the year 1988 if no new
WPC 0324P
3-30
landfills were added to the region. The most optimistic ("Best Case")
scenario indicates closure of all landfills by the year 2011. This scenario
assumes extensive volume reduction and recycling projects. It is clear from
the scenarios evaluated in the RSWMP that new landfills must be sited in
conjunction with developing and using various waste reduction methods to
prevent a serious crisis in sol id waste management in the next decade. The
Department of Public Works is presently engaged in numerous studies to locate
landfill sites in the County. The selection process requires much analysis
and public input and more will be known within the next five,years.
In Iddition to siting new landfill facilities, waste reduction and recovery
projects are underway by San Di ego County. The County Board of Supervisors,
as the agency responsible for regional sol id waste management, has adopted a
pol icy to reduce waste quantities to the landfills and promote alternative
di sposal methods. The pol icy establ i shes that landfi 11 ing is the preferred
disposal method only for wastes that cannot be recycled or processed and for
the residual from processing. This policy promotes the use of alternatives
such as resource recovery to produce energy or animal food sources and seeks
funding for such projects. The pol icy also encourages 1 ifestyle changes to
reduce per capita waste generation and increase recycl ing, and it encourages
the use of additional volume reduction methods such as shredding. The city is
currently applying for a grant to fund a recycling feasibility study.
In summary, it was concluded that the sol id waste master planning and long
range goals, as administered by San Diego County and updated regularly in the
Regi ona 1 Sol id Waste Management Pl an, are cons idered adequate in address i ng
the future disposal needs of the County (including the Chula Vista sphere of
influence). Plans for site enhancement projects at existing landfills, waste
volume reduction and waste-to-energy projects, as well as the current studies
to locate new landfill sites in the County will benefit the planning area in
the future by providing additional landfill capacity. If these plans are
impl emented, capaci ty at the Otay Landfi 11 shoul d be adequate for meeting
future sol id waste demands, and no a lternat i ve di sposa 1 methods shoul d be
required for accommodating the planning area requirements in the next twenty
years. Figure 3-9 depicts the current and proposed solid waste disposal site
within the general plan area.

Citv recocnizes that while APTEC II's total cacacitv far exceeds Chula Vista's
croiected total waste treatment needs. not all of the Citv's treatment needs
are met bv APTEC II. Some local wastes recuire treatments not crovided at
APTEC II. and as in the case of incineration. not within San Dieco County.

4.' fi/SECONDARY SCHOOL SYSTEM
The Sweetwater Union High School District has prepared a master plan for the
expansion of its facilities. The plan includes the district's population
composition, demographic profile, enrollment history and facilities
inventory. From this plan, the district establishes student generation
factors and development standards for the construction of new schools.
The Sweetwater Union High School District Master plan is a public document and
available for review and/or reproduction at the district offices.
4._ Z ELEMENTARY SCHOOL SYSTEM
The Master Plan for the Chula Vista City School District is anticipated for
completion in 1989. The plan will include the district's population
composition, demographic profile, enrollment history and facilities
inventory. Based on this plan, the district will establish student generation
factors and project facility needs.
4.7 a LIBRARY SYSTEM
The City has prepared a master plan for the Chula Vista Library system. The
basic role of the Chula Vista Public Library will continue as a service and
cultural center for people, a source of information in the community for
purposes of business, social, governmental, practical and enjoyment. .
The projected growth of the City will require more library space. The master
plan call s for the Central Li brary to cont i nue to serve the Central Chul a
WPC 0324P
3-35
Vista and Bayfront areas at its present size. In addition, the plans calls
for the construction of two new full service libraries. The first is to be in
the Montgomery area to serve the approximately 50,000 existing residents. At
the time the new library is constructed, one or both of the small neighborhood
branches are expected to becl osed. The second new 1 i brary will be in the
Sweetwater/Bonita area and will also be a full service facility. This library
is planned to be built in two phases as population increases.
The fourth 1 i brary of the master pl an system is a small er 1 i brary for the
Eastern Territories. This will serve the population of this newly developing
area and will be built as is warranted.
The master plan evaluated a total of seven sites in the Montgomery area. With
little vacant land available all alternatives to new construction should be
thoroughly explored such as renovation of exiting buildings. In the
Sweetwater area a site has been set aside for a future library and five other
sites have been evaluated. An interim library and five other sites have been
evaluated. An interim 1ibrary facility for Eastern Territories will be
provided in the EastLake Village Shopping Center when it is constructed. The
location is available on a five-year rent free basis. The permanent facility
is expected to be constructed on a site in EastLake. The total master planned
1 i brary system at buil dout will i ncl ude three full service 1 i braries and one
library in Eastern Territories that will be sized in accordance with demand.
5. POLICIES AND GUIDELINES
Providing for adequate infrastructure development within the general area as
it grows, requires the application of certain policies and guidelines. Those
policies and guidelines, as contained in this section, will assist the user in
interpret i ng the goals and object i ves of Publ i c Servi ces Ph,n whi ch will
assure that the quality of life in Chula Vista in maintained or enhanced in
future years.
5.1 WATER SUPPLY POLICIES
Water supply for the general plan area comes primarily from two sources: local
water derived from precipitation and stored in Sweetwater Reservoir, and
imported water transported by the San Diego County Water Authority. Proposed
future development and conversion of now vacant land to other uses will place
ever-increasing demands on these supplies. Potential limitations on the
availability of both supplies highlights the need to combine long-term
planning for water supply with long-term planning for community development in
Chula Vista.
(1)
The City shall actively participate in the water master planning process
by the Otay Water District and Sweetwater Authority. The City shall use
the master plan to assist in assigning the highest priorities to projects
that will alleviate existing water supply problems such as insufficient
transmission capacity or storage.
WPC 0324P
3-36
(2)
Prior to approval of development appl ications, the City shall determine
that there is adequate water to accommodate the demand generated by the
proposed development.
The City shall encourage and monitor water conservation techniques and
programs and shall educate the community with respect to the importance
of these efforts. This shall include the following:
Mandate the use of water conservation devices in new development
including low water use toilets, shower fixture and other amenities.
Promote low water usage landscaping that is drought tolerant.
Mandate the use of reclaimed wastewater for all reasonable
applications except in severe hardship cases.
Establish, in concert with the water agencies, a public information
program to educate the communi ty concerni ng water conservat i on and
the use of reclaimed wastewater.
(3)
Establish a water conservation monitoring program.
(4) The city shall strongly encourage the San Diego County Water Authority to
make the necessary improvements required to assure adequate water supply
to Chula Vista.
5.2 WASTEWATER SERVICE POLICIES
The collection and disposal of wastewater generated within the general plan
area will require much study and planning in the future. With the Metro
system undergoing significant change coupled with the need to implement an
effect i ve recl amat i on program, the City wi 11 be faced wi th major deci s ions
regarding the ultimate wastewater system configuration. An up-to-date
Wastewater Master Plan, administered by the City, will ensure the adequacy of
future facil ities to meet the demands imposed by future development. The
extension of wastewater service and the availability of capacity will greatly
influence how much and where Chula Vista grows.
(1 )
(2)
(3)
.'
(4)
The City shall use the Wastewater Master Plan as a guide to the future
wastewater collection and treatment facility requirements.
Proposed facilities shall conform to this general plan's policies for
land use, development location and timing.
Prior to approval of development appl ications, the City shall determine
that there is adequate capacity to accommodate the wastewater generated
by the proposed development.
Costs of improvements which are necessary to serve new development, such
as extensions of service and pump facilities, shall be financed by the
WPC 0324P
3-37
developer. Facilities shall be constructed to City standards and
dedicated to the City. This policy does not preclude the use of
assessment districts or similar mechanisms to finance improvements.
Exi st i ng res i dents shoul d not have to pay for improvements necessi tated
only b:,: new development. .
However, if existing residents benefit by increasing their property's
housing density, they shall be required to participate in the required
improvements.
(5) New development to be served by septic systems in the Ci ty and in the
County shall be revi ewed by the County Health Department to ensure the
adequacy of the design, the suitabil ity of the soil s to accommodate
on-site disposal systems and the protection of nearby surface and
groundwater systems. Septic systems shall be permitted only as a last
resort if gravity flow to the City's sewer system is not possible and
only on parcels at least one acre in size, provided that the City is
satisfied that the above criteria are met.
Actively participate in the Metro expansion planning process and, where
appropriate, evaluate reasonable alternatives which will eliminate Chula
Vista's dependence on Metro.
(7) The City shall authorize a feasibility study with respect to implementing
a phased reclamation program to promote drinking water conservation. The
study should address participating in the Metro reclamation program or
establishing an independent program.
(6)
5.3 DRAINAGE AND FLOOD CONTROL POLICIES
Collecting and conveying stormwater from present and future dev&loped area is
essential to protecting lives and property. Development of the largely
undeveloped Eastern Territories could significantly affect the existing
downstream drainage and flood control facilities in Central Chula Vista if not
properly regulated.
,
(1)
The City shall use the, Drainage and Flood Control Master Plan as a guide
to the future stormwater facility development.
If improvements are necessary to accommodate new development, it shaLl be
the developer's responsibility to bear the costs of such improvements, to
construct the facil it ies to City standards and to dedicate them to the
City. As an alternative, the City may establish and the developer shall
pay drainage basin fees for financing the required facil ities necessary
to preclude a negative impact on the downstream facilities.
Prior to approval of a development application, the City shall determine
that there is adequate downstream stormwater drainage capacity to
accommodate the runoff generated by future development within the
project's drainage basin.
(2)
(3)
WPC 0324P
3-38
(4) The City shall mandate the development of on-site detention of stormwater
flows such that, where practical, existing downstream structures will not
be overloaded.
(5) The City shall require the development of on-site sediment control a part
of each project.
(6) The City shall discourage disruption of the natural landforms and
encourage the maximum use of natural drainageways in new development.
Where possible, non-structural flood protection methods, such as natural
channel s or improved channel s which simul ate natural channel s should be
considered as an alternative to constructing concrete channels to protect
and stabilize land areas.
5.4 SOLID ~P/~~~ WASTE CONTROL POLICIES
The City's solid waste is disposed of in the Otay Landfill located within the
general plan area. The site is expected to close in the foreseeable future if
waste reduction technologies are not employed. 1M/;r;Wi'N/f"IJMtMIWN~,rrt

General Areas
The Tanner Act lAB 2948) reQuires the maooinQ of "Qeneral areas" within which
hazardous waste facilities miQht be established. subiect to evaluation based
on the sit i no criteri a set forth in the subseQuent section. "General areas"
are intended to illustrate the extent and di stri but i on of Dotent ial sit i no
oooortunities within (hula Vista and as such. are desiQned alone with the
1i1jna criteria as first steo in analvzina the aooroori~teness of a Darticular
site for a hazardous waste facilitv. The "oeneral areas" ARE NOT recommended
locations for such facilities. nor are thev intended as a soecific auide to
locations where facilitv sitinQ aoolications are encouraeed. However.
facilitv Drooosals should be considered onlv if thev are within the ~eneral
areas desiQnated herein.
WPC 0324P

Existina industrial areas. and future industrial areas desianated in the Chula
Vista General Plan were included as "aeneral areas" in ChaDter IX and ADDendix
IX-B of the COHWMP. These areas do not necessarilv reDresent all the
available locations for facilities. as additional land desianated as
industrial throuah future General Plan amendments and rezoninas should also be
considered for Dossible inclusion as a "aeneral area". Likewise. aoolication
of sitina criteria to more sDecific local conditions mav Drove some of the
identified aeneralized areas as unacceotable.
Based on a review of more soecific local land use conditions in relation to
several Drominent sitina criteria. Fiaure 3-10 deDicts a refinement of
"aeneral areas" within which hazardous waste facilitv DroDosals would be
cons i dered in the Chul a Vi sta Pl ann i nq Area. These refi ned "aenera 1 areas"
shall orevail over the "aeneral areas" described in the COHWMP and its
aDDendices. and shall be subiect to review and amendment from time-to-time as
necessitated by chanqina land use and other local conditions. For
clarification. the followina Drescribes those industriallv desianated and
zoned areas whi ch have Dresentl v been removed from the COHWMP' s "aenera 1
areas" inventory:
- Montaomery/Otav Community: Bounded bv L Street on the north. Interstate

Sitina Criteria
Under the Tanner Act tAB 2948). local aovernment is reQuired to adoDt .sitinQ
criteria" to be aDolied in evaluatina ~azardous waste facilitv croDosals
within the creviouslv established "aeneral areas". Sitina criteria are those
oDerational. financial. land use and transDortation conditions which must be
met if a hazardous waste manaaement facility is to be Dermitted at a sDecific
site. Sitina criteria are both aualitative and ouantitative in nature. and as
the focus of the sitina orocess are crimarilv intended to ensure the
sufficient Drotection of Dublic health. safetv and welfare. and environmental
resources.
The criteria are desianed somewhat aenericallv in that the v aDDlv to
evaluation of a broad ranQe of hazardous waste facilities and manaaement
technoloaies which can varv areatly in their size. volume. and tVDe of waste
stream(s) handled. and which inherentlv mav differ substantiallv in their
Dotential land use. environmental. and oublic health imDacts. While this
aeneric nature of the criteria Drovides needed flexibilitv in the local review
Drocess. it also necessitates that facilitv review be conducted carefullY and

Recoanizina the influence of more soecific local conditions on the develooment
and aDDlication of sitinQ criteria. Section 25135.7(d) of the Health and
Safety Code allows cities to establish more strinQent Dlannina reQuirements or
sitina criteria than those in the COHWMP. In order to assure that hazardous
waste facilities are considered with the hiahest reaard for the health. safetv
and welfare of the citizens of Chula Vista. and the continued Dreservation and
Drotection of its natural resources. the followina modified sitinQ criteria
shall be emDloyed in the evaluation of hazardous waste facilitv DroDosals

At Dresent. however. there does not exist clear direction as to how a local
jurisdiction is to consider and aDolv fair share DrinciDles to sDecific
facilitv sitina DroDosals. The DrinciDles contained in the COHWMP. as derived
from SCHWMA's Reaional Action Plan. focus on whether countv-wide needs for
waste treatment and di sDosal are beina met throuah either facil itv caDacitv

direct authoritv over. are not beina fully addressed. This situation does not
recoanize iurisdictions within the Countv which are already host to hazardous
waste facil ities. nor does it Drescribe how a Countv mav acceDtablv develop
internal fair share Dolicies which define when a local iurisdiction has met
its reasonable fair share of reaional resoonsibil ities. As the fair share
conceots are somewhat new. further efforts are necessary to develoD more

5.' 6 SCHOOL DEVELOPMENT POLICIES
In 1987, wi th the passage of Assembly Bi 11 2926, the State of Ca 1 iforni a
declared the issue of new school construction to be of statewide concern.
That legislation authorized school districts to collect fees as a prerequisite
for residential and commercial/industrial development. Fee collection of up
to $1. 50 per square foot of habi tabl e area for res ident i a 1 development and
$0.25 per square foot of new commercial/industrial development was approved.
The levy may be increased annually to accommodate inflation if authorized by
the State of California State Allocation Board.
Fees coll ected pursuant to AB 2926 may only be used to provide temporary
facilities and/or service the matching funds requirement should the district
participate in the Leroy Green Lease-Purchase School Facilities Program.
Additional revenue generating mechanisms, including financing for permanent
facilities are:
1. General Obligation Bonds
2. Mello-Roos Community Facilities Districts
3. Certificates of Participation
4. District's share of Redevelopment Funds
5. Sale of Surplus Land
6. Developer fee programs.
All new school related development must be approved by the State of California
Office of State Architect prior to construction. To facil itate approval at
the state level, the school districts use the following criteria:
1. The new senior high .schools shall be constructed to accommodate
approximately 2,400 students and shall be designed to allow for a
four-year curriculum.
2. New junior high/middle schools shall be constructed to accommodate
approximately 1,400 students.
3. Newel ementary school s shall be constructed to accommodate
approximately 650 students.

4. A senior high school shall consist of at least 50 usable acres; a
junior high/middle school site; 20 usable acres. The acreages may
be reduced to encourage the joint use of community parks where
appropriate.
An elementary school site shall consist
acres. The di strict encourages joi nt
appropriate.
6. School sites shall be located in proximity to major arterials, and
primary ingress and egress to the site shall be controlled by a
signalized intersection.
of at least 10 usable

7. The proposed land uses adjacent to a school site shall be planned in
such a manner as to minimize noise impacts and maximize harmonious
development between the two uses.
B. To further community development and enhance the qual ity of 1 ife,
school s should be centrally located in residenti al neighborhoods in
order to best serve the majority of the student population.
9. School development is subject to the California Environmental
Quality Act (CEQA). Therefore, prior to accepting the dedication of
a school site, the district will require an examination of the
existing environmental conditions (seismology and geology, etc.) to
determine its adequacy.
5.6 LIBRARY DEVELOPMENT POLICIES
In order to serve the public in the most effective and efficient manner the
selection of new library sites should be based on the following criteria:
1. Proximity to Community Activity Centers or neighborhood retail
centers.
2. High visibility from the streets providing access.
3. Primary ingress and egress to the site controlled by a signalized
intersection or other adequate vehicular control.
4. Compatibility with the surrounding neighborhood character.
5. Minimum displacement of existing residents and businesses.
6. Minimum costs.
.'
In addition, site should be of sufficient size, shape and topography to
provide for the development of a library facility that will meet the following
criteri a:
1. One level structure of the required size to meet the service
standards.
2. Public and staff parking in accordance with City standards.
WPC 0324P 3-61
3. Adequate allowances for landscaping and building setbacks
requirements.
The planning and design for the library buildings should be in accordance with
the following guidelines.
1. Library space of .5 to .7 gross square feet per resident.
2. Three books per capita, plus spoken word audio cassettes, video
cassettes and compact disks.
