PUBLIC HEARING:
PCM-94-20/PCA-94-02; Consideration of amendments to
the Citv Landscape Manual and associated amendments to
the Municipal Code - Citv initiated
A, BACKGROUND
In 1990, the California State Legislature enacted Assembly Bill 325, the Water Conservation in
Landscaping Act. AB 325 requires cities and counties to adopt a "Water Efficient Landscape
Ordinance" or be governed by a draft "Model Water-Efficient Landscape Ordinance" developed
by the State Department of Water Resources, According to AB 325, the model water efficient
landscape ordinance automatically went into effect in all communities that had not adopted their
own ordinance by January 1, 1993,
The Landscape Manual has been revised primarily to include the water conservation measures
called for by AB 325, A copy of the draft Manual was filed with the State in September, 1992,
and a representative of the State Department of Water Resources has acknowledged the City's
compliance with AB 325, The Manual has also been updated to include standards for public
landscape installations, and to formally incorporate current practices from its last revision in
1978,
New sections include "Public Landscaping", "Drought Tolerant Plantings", "Fire Retardant
Plantings", "Water Management for Landscaping", a sample Water Management Plan, and other
minor miscellaneous amendments, Certain technical and procedural amendments to the
Municipal Code to reflect the revised provisions in the Manual are included in the attached
ordinance,
On July 25, 1994, the Resource Conservation Commission voted 5-0 to recommend approval
of the amended Manual and associated code amendments, On July 21, 1994, the Parks and
Recreation Commission voted 6-0 to recommend approval of the Public Landscaping section of
the Manual.
The Environmental Review Coordinator has determined that the amended Landscape Manual is
exempt from environmental review as a regulatory measure designed to enhance the quality of
the environment (Class 8 exemption under CEQA) ,
B, RECOMMENDATION
Adopt Resolution No, PCM-94-20/PCA-94-02 recommending that the City Council approve the
amendments to the City Landscape Manual and associated amendments to the Municipal Code
in accordance with the findings contained in the attached Draft City Council Resolution and
Ordinance,

C, DISCUSSION
Water Conservation Measures
The water conservation measures within the Landscape Manual can be summarized as follows:
1. A Water Management Plan is required for all industrial, commercial, and multi-family
projects, The Water Management plan is prepared by the property developer and
provided to the City as part of each Landscape Plan submitted for approval. The Water
Management Plan must include specific water conservation methods and any expected
water savings on each project. A sample water management plan has been provided
within the revised Manual to guide applicants,
2, Where available, reclaimed water use is required for all industrial, commercial, and
multi-family projects, and all developer-installed landscaping within single-family
projects, Where reclaimed water is not available, potable water is allowed to be utilized,
3, All landscape installations subject to the provisions of the Landscape Manual are required
to be certified for completion by the project Landscape Architect, Civil Engineer, or
Architect, prior to building occupancy or turnover to the City, Post-installation
certification will ensure proper and complete landscape installation in accordance with
approved plans,
4, New landscape design criteria have been added that support low-water use landscape
design and efficient water-use irrigation design, These criteria include promoting the use
of efficient irrigation components to ensure state-of-the-art irrigation design,
5, A public information and education program on water conservation is required for single-
family projects, This program will require developers to provide written information on
water conservation techniques to all new homeowners, In addition, at least one home
within each model complex is required to physically demonstrate landscaping
emphasizing drought tolerant plantings, Signs are required to direct the attention of
prosp.ective purchasers to drought tolerant features within the landscape design,
Drought Tolerant/Fire Retardant Plantings,
In addition to those sections which address water conservation, a new section on "Fire
Retardant/Drought Tolerant Plants" has been added to bring the text of the Manual into
conformance with Council Policy 476-04, which mandates the use of drought tolerant and fire
retardant plantings, This policy has been implemented by staff since its adoption in 1988,
These modifications will incorporate the measures into the text of the Landscape Manual and
allow repeal of the policy,

Public Landscaping
The new Public Landscaping section addresses public works projects, including civic facilities,
parks, open space, and streetscape installations, This section also implements the authority of
the Director of Parks and Recreation set forth in Chapter 17,10 of the Municipal Code, The
specific topics covered include submittal requirements, graphic and standard requirements,
design standards and criteria, landscaping, irrigation, and trails, An appendix outlines
recommended plant material.
The Public section is consistent with current City ordinances with the exception of the design
and size of parking stalls, The City requirement for a standard 90 degree parking stall is 9'
wide x 19' long, and a compact stall 7'-6" wide x 15' long, both with 24' wide back-up
area/drive lanes, The proposal for park installations is 10' wide x 18' deep, with no compact
stalls considered, and back-up area/drive lane 26' wide,
The rationale for having a different standard is that the park users typically have larger vehicles
with more people and additional supplies and equipment, The larger parking stall dimensions
provide more space between vehicles for doors to be opened completely, and greater width in
the drive lanes for ease of movement throughout the parking lot. The parking lots at Terra Nova
Park and Rohr Park have been designed and installed using these dimensions,
Miscellaneous Amendments to the Manual and Code
The most significant of the miscellaneous revisions to update the Manual to current practice are
as follows:
1. The Municipal Code (19,14.485) currently requires that a site be improved and brought
into current conformance with the Landscape Manual when any remodeling or site (other
than single family) improvement exceeds a dollar value of $10,000, This dollar amount
was established in 1978, In order to reflect a better comparable value in today's market,
the dollar value is recommended to be increased to $20,000, This is consistent with the
dollar value now used by Engineering for exaction of public improvements,
2, The Manual now reflects the fact that the inspection responsibility for the City's Open
Space districts has been transferred from the City Landscape Architect to the Parks
Landscape Architect. This transfer of responsibility occurred in 1989 when the Parks
Department created a staff Landscape Architect position,
3, A requirement has been added to require water efficient, drought tolerant landscaping
within private open space areas other than those used for recreation,
The amendments to the Landscape Manual require certain technical and procedural amendments
to the Municipal Code, These are included in the attached draft City Council ordinance,

Review of the Manual
The draft of the revised Landscape Manual has been reviewed by the California Native Plant
Society, Sierra Club, Chamber of Commerce, Crossroads, local water purveyors, and
SANDAG, To date, the City has not received any adverse comments or suggestions from these
outside groups, The local chapter of the American Society of Landscape Architects has also
reviewed and endorsed the document except for some minor technical clarifications that will be
resolved prior to Council adoption of the Manual.
A workshop was held on April 25th to receive input from representatives of the McMillin,
Baldwin, Gafcon (Sunbow) and Eastlake development companies, As a result of the workshop,
some minor changes were made to the Manual. One significant issue remains with the
developers as discussed below,
Within the Parks section, a requirement for irrigation systems to be designed to meet a set
"watering window" remains an issue for them, They expressed that, in order to satisfy this
requirement, additional irrigation meters would be required, This, they felt, was above and
beyond what was provided in the past, and if required would have a significant fiscal impact.
They requested that this be reconsidered,
Staff has concluded that this requirement is consistent with AB 325 and Otay Water districts
requirements, and is necessary to satisfy the City's parks and open space maintenance
requirements, This position is supported by the Parks and Recreation Commission and the
requirement remains within the Manual.
As noted earlier in this report, the draft Landscape Manual has been reviewed by the State
Department of Water Resources and found to be in compliance with AB 325, The Department
of Water Resources is requesting for their records a copy of the final Council approval,
resolution, and revised Manual.
The City Council resolution reflects the fact that the amended Manual is consistent with the two
regional water conservation measures recommended in the Regional Growth Management
Strategy (RGMS), Those measures are: 1) the use of reclaimed water, when available, and 2)
the "efficient use of water" in landscaping,
Coordination with Otav Water District
On March 18, 1992, the Otay Water District adopted their own ordinance regarding water use
in landscaping, The district approaches water conservation through a "water allocation"
program, which establishes a maximum amount of water to be used within a project area, An
area of interface between the City and the water district could occur if, for instance, an applicant
had estimated a total water use over the amount that Otay would allocate, thus requiring a
redesign and recalculation, City staff and representatives of the water district are currently
City Planning Commission
Agenda Item for Meeting of September 28, 1994
Page 5
discussing a way in which this can be accomplished in a cooperative and coordinated manner.
Otay has reviewed this final draft, and finds this revised Manual to be very complete and
supportive in the effort to conserve water, and has given their endorsement of this revised
Manual.
State ModellComDarison
Staff has considered the state Model Water Efficient Landscape Ordinance and has effectively
utilized most but not all of its provisions as evidenced by the following matrix, The Water
Conservation in Landscaping Act provides that "to the extent feasible, local agencies shall
consider the provisions of the Model Code". The following is a comparison of the State Model
and the City Landscape Manual:

will facilitate water conservation and fire safety, and update the Manual with respect to
current practices and procedures, As a result, we are recommending approval in

By Resolution No, , the Chula Vista City Council approved this updated and expanded
Landscape Manual and repealed its predecessor. The City Ordinances that implements this manual
are located within Titles 17 and 19 of the Chula Vista Municipal Code, This revised manual
addresses issues specific to site development, landscaping and irrigation, both for private
development and for public projects, The design and implementation of a project's landscape
should address all functional and aesthetic site specific design issues, in addition to integrating the
project into the immediate surroundings and adjacent properties, The Manual also specifies
materials that will assist the City and its residents in achieving long range durability and cost
effectiveness,
Because of the semi,arid climate that Chula Vista is located in, and the increasing demand for
limited imported water resources that selVe Southern California, the principles of drought tolerant,
or xeriscape landscaping, are emphasized, The ability to conselVe water while establishing and
maintaining landscape installations is a primary concern for the future of the landscape industry and
the region in general. This effort is not only desirable, it is a legal requirement of the State of
California, as set forth in Government Code Section 65590 et. seq, (AB325 1990), and the State
Department of Water Resources Water Efficient Landscape Ordinance,
With these concepts in mind, this landscape manual outlines the process, requirements, and support
information necessary for the review and approval of a project being processed through the City of
Chula Vista,
The manual is comprised of three main components, Part One, General City Requirements,
addresses the overall requiremenls and processes for a project. Part Two, Private, addresses items
specific to private projects such as residential subdivisions and commercial centers, Part Three,
Public which is divided into six (6) section, addresses the requirements and criteria of public projects
including parks, open space and streetscapes (whether a City Public Works project or a private
"turnkey" project), These Public Projects are further implemented by Standard Project specifications
available from the Parks and Recreation Department.
The policies and requirements described in this manual are minimum standards, Projects must meet
or exceed these standards, If any specific questions regarding a project require clarification, please
contact either the Planning Department for private development projects, or the Parks and
Recreation Department for public projects.

Goal:
The goal of this water management plan is to conserve water by combining water
conserving design practices with guidelines for the landscape irrigation manager, This plan
will provide the owner with the necessary information to maintain systems in peak
performance, and make decisions on when and how much to irrigate,
This landscape water management plan provides information for the irrigation manager
to implement the following water conservation concepts:
a, Irrigation systems should be maintained to distribute water as uniformly as
possible,
b, To assure adeauate irril!ation of all areas the system should be operated only long
enough to apply water to a soil depth that the plants' roots utilize, Verify with soil
probe,
c, The irrigation system is designed for maintenance and operation to avoid surface
runoff,

Soil and Climatic Conditions:
a, Soil Conditions are widely variable for the project area, The soil ranges from silty
sand and decomposed granite to rocky granitic concentrations,
b, Climatic Conditions, The site, though located in a Southern California thermal
belt, is influenced by south coastal cloud, fog and wind conditions, and sometimes
experiences Santa Ana winds from the desert.
Annual Precipitation Rates, (Rainfall in Inches per Year):
The annual "historical" precipitation rate (average from 1940 to 1991) is 9.45 inches per
year. Currently San Diego County is in a drought mode and the historical precipitation
rate may not apply, Forthis reason the annual precipitation rate for 1991 is possibly more
indicative of current precipitation rates,
a, Anticipated ET (evapOtranspiration) , the measurement in inches of soil moisture
consumed by plants and evaporated from the soil: (San Diego County Water
Authority, Model Water Efficient Landscape Ordinance and City of Chula Vista
Landscape Manual limits the ETo to 80% of the measured ETo for calculations
in each locale),
Again, due to current drought conditions both ETo (historical ETo) and ET for
1990 are shown below:

Water Source and Quality:
The irrigation water source will be tapped from an existing and functioning on-site potable
pumped ground water system, This system is operated and maintained by fire station
personnel.
Precipitation Rates, Planted Areas:
The precipitation rates for each variety of planted, irrigated area are as follows (they are
listed by plant type and the sprinkler nozzle servicing them operating at 40 psi),
Trees, Shrubs and Ground Cover:
Series, Low Gallonage, Matched Precipitation Rates, Pressure Compensating Nozzles;
xx' Coverage Radius (full)x,xx PR
xx' Coverage Radius (half)x,xx PR
xx' Coverage Radius (quarter)x,xx PR
Summary of Water Conservation Methods:
The irrigation design and water management program described utilizes known and
documented water conservation principles,
The irrigation equipment and layout in the design reflect the water conservation methods
that have been a standard in the industry, including: an automatic controller with multiple
daily run times, the use of moisture sensors and a rain gauge to interrupt the automatic
programming of the controller when necessary, "head to head" sprinkler layout to increase
distribution uniformity (DU), matched precipitation rate nozzles to increase DU, low
precipitation rate nozzles to decrease the probability of surface runoff, separate irrigation
stations according to: sun exposures; slopes (top and bottom); turf and shrub areas,
The planting plan utilizes hardy native and drought tolerant plant species, adjunct to
existing native areas, Ground cover,type plant masses act as living mulches to shade and
cool soil temperatures and reduce moisture loss, Decorative turf areas are not designed
into this project,
Water Requirements:
The annual anticipated water demand has been estimated in inches, gallons, and acre feet,
Please note that the figures below were arrived at by utilizing 1990 C.I,M,I.S, data, and
the water demand in non-drought years may be lowered by twenty percent. The City of
Chula Vista is adopting the State Department of Water and Power mandate an ETo @
80% of the yearly average ETo, The values shown below will reflect this mandate as
water consumers in the Chula Vista area,

Water Delivery Systems:
The type of irrigation system utilized for this project consists of an automatically
controlled, PVC, pop,up spray system, Many water conserving principles have been
applied in the design, such as:
. An automatic irrie:ation controller that has the capability of being set for multiple
run times in one day for each station, thus reducing run,off by only applying the
amount of water that the soil can absorb at anyone time, Also, the irrigation
manager can set the run times to reflect the current C.I,M,I.S, data,
. Sprinkler head lavout is "head to head", meaning that each sprinkler's coverage
radius reaches to the next sprinkler head in the system, thus providing the best
distribution uniformity (DU) possible,
. Matched precipitation rate nozzles have been utilized, By matched precipitation
rate it is meant that a designer can mix in the same irrigation station nozzles with
varying spray patterns (ie; 90's, 180's, and 36O's) and still have even precipitation
rates throughout the area, again providing better distribution uniformity, This
project analysis allows for low rate irrigation application for trees, shrubs and
ground cover, depending upon soil percolation rate,
. Low precipitation rate nozzles have also been utilized to reduce the amount of
flow on all slopes 10% or greater. (In comparison to conventional or standard
gallonage nozzles which emit considerably more water in the same amount oftime,
increasing the probability of water waste by runoff,)
. Irrie:ation stations (the area that one irrigation valve services) have been separated
to conserve water as follows: sun and shade exposures are separated; slopes are
separated from flat areas; turf and shrub areas are separated, All the areas listed
have different watering requirements, and run times are to be scheduled
individually to reflect current C.I.M,I.S,data and the runoff characteristics of each
station by the Owner or Irrigation Manager.

CONCLUSION:
Under the Summer and Fall conditions, it is critical that native plant materials be kept much closer
to the dry end of the spectrum or bell curve of moisture content, than to the moist and wet end,
Paying close attention to ET observations will give guidance to irrigation application rates (see
summary), Contrary to customary belief, it is not proper horticultural practice to keep the soil
surface in an artificially wetted condition, Optimum field moisture displaces oxygen needed for
creation of biological gasses and nutrients required for healthy root, stem and crown growth,
Nature in its mysticism will always outwit man, It is essential that we avoid trying to be too good
to the flora and accept the natural signals given off by the subject genus or species, As an example,
a broad leaf evergreen may start to curl its leaves as the sun rises hotter in the sky; does this mean
the leaves are drying out? Chances are the opposite is true; Le" the leaf may curl to reduce its
surface area to keep from getting too much light ami/or reduce the actual evaporation rate, Keep
in mind that steady winds cause evaporation also even under cloudy conditions,
The true test of this or any other system as designed is the ability to observe plant behavior before
drowning the plant with water, It does not make sense to irrigate native plants during a rainy season
because native plant materials thrive on seasonal rainfall only; even during times of installation of
the plants, it is unnecessary to maintain optimum moisture for an extended period of time to
guarantee survival. In fact, survival can pretty well be guaranteed by prudent use of a soil probe and
diligent inspection, maintenance and operation of the irrigation system,
The advent of winter and spring conditions will provide ample moisture to the native plant material
for the first season after transplant and may only need minor supplemental (customary psychological)
irrigation, when in reality the native plant material will perform better on neglect,

Section Four
Landscaping:
1. GENERAL.
Every project is unique in terms of site location, adjacent land uses, design constraints, positive
and negative views, etc. The functional, aesthetic, soil moisture, and maintenance requirements
of all proposed plant material are issues that must be taken into consideration in the
development of landscape designs and plans.
The following design guidelines address issues relative to maintenance and site design. It is
the responsibility of the design consultant to design the landscape and make plant material
recommendations that address all relevant site issues and constraints.
Selecting and matching plant material into specific condition areas or 'hydrozones', that have
similar requirements (water and maintenance) is to be emphasized. Native or low water
requiring plants are to be situated away from turf areas, either by distance or elevation. Turf
areas shall be separated from planting areas by walkways or concrete mow curbs.
2. PARKS.
2.1 Planting Design:
2.1.1 Turf:
2.1.1.1 The type of turf grass to be utilized on a park site is dependant upon the
type of activity proposed for the specific area. Common Bermuda shall
be utilized for passive use areas, 'Tifgreen' Hybrid Bermuda shall be
utilized for sport field (softball, soccer, baseball, etc.) applications.
2.1.1.2 The quantity and configuration of turf shall be determined primarily on
the park uses, needs and scale (to a lesser degree in consideration of the
irrigation design). This in an effort to maximize the efficiency of the
irrigation system and the on-going maintenance of the project
installation.
2.1.2 Trees and Shrubs:
2.1.1.1 Plant material locations and spacings for shrub plantings shall be
determined based on 75 - 100% of mature plant size. Spacing shall allow
for proper plant development without crowding, and for basic trimming.
(min. one plant per 100 S.F.)
2.1.1.2 Prostrate spreading shrubs, in conjunction with shredded mulch, shall be
used for groundcover in medium and large scale planting areas. Only in
areas of high visibility will annual, perennial or succulent groundcovers
be proposed and/or considered.

WPC M,\hom.........&IJa_pldBft3 Page 56
2.1.1.3 Plant material selection is to emphasize the use of plant that are
relatively pest and disease resistant and require minimal maintenance.
2.1.1.4 Dense groves of trees shall not be located in turf areas. Grove features
shall be in planting areas, with a 3" minimum layer of shredded mulch or
wood chips as a ground cover.
2.1.1.5 Security and safety shall be a primary consideration in the development
of the plant palette. All plantings along perimeter streets, parking lots
and maintenance walkways shall be selected to allow for visibility into the
site.
2.1.1.6 All non-planted areas shall be covered with a layer of shredded mulch,
wood chip product or decomposed granite to prevent erosion, control
dust and allow for use of the area. The type of cover is to be determined
based on intended use of the area.
2.1.1.7 If the existing configuration or grading of the site creates moist or dry
conditions, then the planting design and selection of plant types shall
emulate these situations.
2.1.3 Drought Tolerant and/or Native Landscapes: Utilize drought tolerant and/or
California native plant material in all planting area applications. This is in an
effort to emphasize reduced water consumption and maintenance requirements.
High water need or high maintenance planting designs are not to be developed
unless the project program or site specific conditions make such a proposal
justifiable. Verify with staff.
2.2 Maintenance:
2.2.1 Site Maintenance:
Landscaping shall be designed and plant material selected to allow for ease of
maintenance throughout the park site. Specifically:
2.2.1.1 The planting design shall be designed in close coordination with the
irrigation system design to assure that the coverage of the irrigation will
not he affected or compromised upon completion of the installation, nor
in the future when the plant material matures.
2.2.1.2 No shrub shall be located within one-half of the mature spread of the
plant to the nearest irrigation head or to the edge of any hardscape
surface (i.e. walkways, mow curbs, parking lots, etc.).
2.2.1.3 All trees located in lawn areas shall he kept a minimum of 10' apart, and
15' away from adjacent hardscape or site furnishings to allow for mowers
to circulate between trees.
2.2.1.4 Trees and irrigation system designs shall be coordinated with one another
to prevent having coverage shadows from either tree trunks or canopies.

3. OPEN SPACE.
3.1 General:
The City's open space maintenance districts are identified and budgeted for using a
"Coding" system. The five (5) different codes are as follows:
. Code 1: Ornamental and high maintenance landscape areas
. Code 2: Lawn areas
. Code 3: Irrigated and erosion control slopes
. Code 4: Non-irrigated native or drought tolerant areas
. Code 5: Undisturbed native habitat
This Coding System is the basis on which the contracts in the Landscape Maintenance
Districts are awarded and administered. With the growth of the City and the installation
and subsequent "turnover" of open space acreage to the Parks & Recreation Department,
effective management and use of both staff and resources is a high priority.
To this end the Parks & Recreation Department, in conjunction with plant ecologists,
biologists, and environmental planners, supports the concept of reestablishment of native
plant communities in the City of Chula Vista open space areas. The revegetation and
establishment of the indigenous native plant communities is beneficial to the wildlife, while
providing many benefits for the City, the citizens and the environment.
The City of Chula Vista is located in the coastal zone of Southern California. The existing
coastal sage scrub and riparian habitat that occurs throughout the City is hoe to several
endangered plant and wildlife species. A balance must be achieved to allow for planned
development and habitat preservation. In addition to this condition is the static supply
of imported water, and the minimal amount oflocal water supplies. A growing population
and demand of water also adds to the pressures of this decision making process. A
sensible approach must be developed to respond to this sensitive equation.
The City is also responsible for establishing the Landscape Maintenance Assessment
Districts that collects the fees to pay for the materials and maintenance of these areas,
which, when landscaped and irrigated using typical plant material and irrigation, consumes
precious natural resources and in turn requires a higher level of maintenance.
In response to this situation, The City of Chula Vista is a proponent of utilizing the
concept of native habitat revegetation. This provides numerous benefits, among which
include:
. The deletion of the need to provide long term irrigation to support the new
installation
. The blending and integration of the newly installed landscape into existing,
undisturbed areas
. The recreation of habitat for the indigenous and endangered plant and wildlife
species that occur in this region
. The reduction in the cost of assessments and demand for contract maintenance
personnel for extensive areas of open space within the City.
. The cost and energy savings realized by having native habitat.

3.2 Revegetation Guidelines:
3.2.1 Drought Tolerant aml!or Native Landscapes: Utilize drought tolerant and/or
California Native plant material in all planting area applications in an effort to
emphasize reduced water consumption and maintenance requirements.
Native and Naturalized Plantings: The restoration of natural plant communities
in areas that have been disturbed by site development is encouraged in transitional
areas and in open space areas. These installations are to be designed such that
minimal maintenance will be required and that irrigation systems mayor may not
be installed. Plant material is to be selected to provide "seamless" transitions from
undisturbed areas to the restoration areas.
These installations shall also to be designed to emulate a natural succession of
plants that will provide an initial cover and surface stabilization, with a sequential
establishment of long term and environmentally correct plant materials and
communities for the specific location.

proceeding with the development of the revegetation plan.
The revegetation guideline provides a recommended standard for the design of
projects that are within one of the following categories:
. City maintained and/or owned open space properties
. Initial landscape installations of open space and park transition areas
. Open Space Landscape Maintenance Districts or Assessment Districts
4. STREETSCAPES.(MEDIANS & PARKWAYS)
4.1 General:
The street medians and parkways are important components of the overall landscape
image for the City and its citizens. While the roadways provide safe and efficient
circulation through the City, the streetscapes weave the landscape fabric into the overall
vehicular interface throughout the City. Gateways at key entries signify the entrances into
Chula Vista and are "anchors "for the beginning and exits for the City's circulation
component.
As identified in Section One, an overall Master Plan is required to be prepared for all
new and renovation streetscape projects in the City. For new streets, this plan is to be
prepared by the developer for review by staff. For street renovation projects, this plan
shall be prepared by staff or by the consultant contracted for the project.
The specific street types that will require landscape planning are as follows:
. Expressway
. Six Lane Prime Arterial
. Six Lane Major
. Four Lane Major

In addition to addressing the landscape issue,. planning at this phase shall address the
inclusion of trails or bike lanes as a component of the layout and the cross section, as per
the City General Plan. See Section Six, "General Use and Recreation Trails" for specific
information.
4.2 Soecific:
4.2.1 Medians:
4.2.1.1 Street medians in the City of Chula Vista are required by ordinance to
conform to the 60/40 ratio of hardscape to planting area. Within the
medians the plant material is to be comprised of trees, shrubs and
groundcovers. No turf is to be proposed or installed in center medians.
4.2.1.2 Specific plant material shall be as proposed in the master plan of the
project. When developing the plant palette, consideration shall be given
to the location of the project (i.e. bayfront, valley, riparian, mesa, inland,
etc.). Plant selection should reinforce or emulate the climatic and
locational aspects of each street segment.
4.2.1.3 Hardscape for the medians shall reinforce and be consistent with the
theme or concept that is being proposed with the plant palette. Actual
layout and relationship of landscape to hardscape can be flexible based
on the location and proposed design concept.
4.2.2 Parkways:
4.2.1.1 Parkways adjacent to the major roadways specified above shall reinforce
the concept and image being created by the median design and plant
palette. The minimum width of a parkway is 5', with a maximum width
of 30'. When sufficient area is available or if a project planning
document requires, a 10' wide recreational trail in a meandering layout
shall be provided. This will provide for a sense of movement and create
opportunities for the design of "drifts" or "masses" of plant material.
4.2.1.2 Specific plant material shall be as proposed in the master plan of the
project. When developing the plant palette, consideration shall be given
to the location of the project (i.e. bayfront, valley, riparian, mesa, inland,
etc.). Plant selection should reinforce or emulate the climatic and
loeational aspects of each street segment. Turf can be proposed at
intersections or in areas that merit the consideration of turf in
relationship to adjacent projects.

Section Five
Irrigation:
1. GENERAL.
The City of Chula Vista is primarily serviced by two water agencies, the Sweetwater Authority
and the Otay Water District. The Sweetwater Authority services the western portion ofthe city,
and the Otay Water District services the eastern portion of the city. With the large scale
development and construction occurring in the east, and Otay Water District being the
purveyor, the design requirements relative to volume, for the City, are based on the Otay Water
District allocation standards.
The Parks and Recreation Department has the responsibility of reviewing the designs and plans
for parks, open space, and streetscape, irrigation installations. One of the primary
considerations is to assure that these irrigation systems will be able to meet the time constraints
placed on the operation of these systems within the prescribed ''windows of operation" or
quantity of water available during the course of the year.
Therefore, the design of irrigation systems for both parks, open space and streetscape areas is
of extreme importance, for the efficient distribution of water to all landscaped areas and getting
correct application of water to the subsurface depths for the specific plants being irrigated. The
issue of preventing any surface runoff or waste of water in the process of operation of any and
all systems is also a strict requirement.
The Parks and Recreation Department has developed irrigation design criteria and a list of
irrigation components that have been deemed acceptable for use on parks, open space and
streetscape installations. The following design requirements address issues relative to the design
and installation of irrigation systems.
Refer to the Section One of the Landscape Manual for a detailed description of the City's
requirements relating to irrigation water use and the water management plan.
2. IRRIGATION DESIGN.
Any irrigation system that is in a park, open space or streetscape that is to be turned over
to the City must be designed and installed to meet the following requirements:
2.1 P.O.C.:
2.1.1 AIl projects shall to be analyzed to determine the size of the water meter and
pressure mainline relative to the scale of the irrigated area at the project site.

pads. See irrigation material list for manufacturer and Standard Drawing(s) 11
and 12 for installation.
2.1.2 Enclosures shall be installed at approved locations. Location to allow for
observation of area serviced by controller.
2.1.3 A master controller and slave controllers can be installed, when more than one
controller is required for a specific project installation. The master controller will
provide for remote access to program all the controllers that are "hard wired" to
the master. The access to program the controllers shall be through either radio
or telephone. Verify with staff for correct components and feature requirements.
2.1.4 In remote locations, the enclosure can be a front/back unit that allows for the
installation of the electric meter for the controller.

Trails: General use and Recreation Trails
1. GENERAL.
As identified in the City General Plan, the identification of trails is to be considered in all
projects, is to be considered. Trails shall be included to provide connections from parks, schools
and public facilities to each other, in addition to accessing city open space areas and trails.
Trails provide for the use of alternative modes of transportation, as well as recreational
activities. Two types of trails are used within the city and open space areas. They are the
"General Use Trail" and the "Recreation Trail".
This section addresses the two (2) types of trails to be considered, in addition to the design
requirements and construction detailing.
2. TRAIL TYPES.

differences being the size and detailing. A general use trail shall conform to the CalTrans
"Bikeway Planning and Design Criteria" (7-1000) design standards and to be constructed
as follows:
2.1.1 A minimum of 10' wide x 4" thick, concrete with #8 wire mesh throughout,
minimum. Trail shall be constructed on compacted subgrade and designed to be
accessible for physically disabled individuals.
2.1.2 A post and rail fence shall be provided along the side of the trail when a down
slope condition higher than 5' exists within 5' adjacent to either side of the trail.
2.1.3 A minimum overhead clearance of 12'.0" shall be provided and maintained.
2.2 Recreational Trail:
A Recreation trail is a trail that is more rural in character and material. A recreation trail
shall conform to the Caltrans "Bikeway Planning and Design Criteria" (7-1000) design
standards and to be constructed as follows:
2.1.1 Trails shall be constructed with decomposed granite (d.g.), 6" thick, minimum and
may be contained on the edges with either a redwood header or a concrete mow
curb.
2.1.2 A post and rail fence shall be provided along the side of the trail when a slope
condition higher than 5' exists within 5' adjacent to either side of the trail.
