CITY ATTY\Ei_
RECOMMENDED ACTION:
Adopt Resolution No. ^?-5 approving the revised Landscape Manual, Policies
and Requirements, and introducing Ordinance No. /1/5 - /£> */* deleting the word
"guidelines" from Title 11, Chapter 11.06, Section 11.06.025 of the Municipal Code.
ITEM DISCUSSION;
On October 16, 1990, after staff presentation, City Council comments and public
discussion by the Green Industry and the American Society of Landscape Architects,
staff was directed to evaluate the various issues raised and return to Council with further
recommendations and/or clarifications related to the proposed revised Landscape
Manual.
The following issues and comments were expressed by the City Council.
1. Further Review — That the Green Industry Council and other interested
organizations have an opportunity to review the document.
Action: Staff has met with representatives of the Green Industry Council, the
California Association of Nurserymen, and the American Society of Landscape
Architects and have discussed their concerns and made revisions to the Manual
where appropriate.
2. Water Meters ~ The requirement for two water meters (a separate meter for
landscaping) should only apply to commercial and industrial projects and
"common areas" within residential projects (not individual homeowners' lots).
Action: The requirement has been changed to reflect this comment. (Refer to
page 28, section C.3-5.2.)
3. Fountains -- Clarify that fountains must utilize reclaimed water if available.
Action: The requirement has been clarified to include this comment. (See page
29, section C.3-6.2.)
4. Timing of Landscape Installation - Some commercial/industrial projects have
large areas of turf that are installed far in advance of the time when buildings are
constructed.
AB No. , Page 2
Discussion: Large "master planned" industrial/commercial projects typically
involve "pre-landscaping" of the project and individual lot perimeters prior to
construction of buildings and landscaping of individual lots. This is a result of
conditions of approval and/or the developer's desire for marketing.
By limiting the amount of high water consuming turf around the perimeters,
developers may still be able to "pre-landscape" around their site, enhancing the
public streetscape as well as their project without impacting water resources.
Action: The Manual limits turf in commercial/industrial projects to 10% (cool
season) and 15% (warm season) of the landscaped area. (Refer to page 27,
section C.3-4.2-1 B.)
5. Turf and Reclaimed Water -- The City may want to relax the turf limitation in
cases where reclaimed water is available.
Discussion: Staff has discussed this issue with the Carlsbad Water District, and
the consensus is that the City may want to still limit turf even when reclaimed
water is available. The reason is that the uncertain future supply of reclaimed
water may warrant continued conservation of reclaimed water as well as potable
water resources.
Action: No changes to the Manual have been made related to this issue at this
time.
6. Turf % Limitation -- Reevaluate turf limitations after review of scientific data
and discussions with interested organizations. Consider larger allowable turf
areas in high density residential projects.
Discussion: Staff has evaluated scientific data (refer to Exhibit 5), met with the
County of San Diego Technical Advisory Committee (currently addressing the
same issues related to turf limitations) and with representatives of the Green
Industry Council, California Association of Nurserymen, and the American
Society of Landscape Architects. Based on this input, staff developed three
alternatives for turf limitations, evaluated each alternative, and discussed the
alternatives with the interested organizations. Staff recommends "Alternative 3",
which bases the allowable percentage of turf on project type. (Refer to
Exhibit 4.)
Action: Staff has revised the requirement to base the percent limitation of turf
on project type, allowing for turf areas to be increased in relationship to the
density of residential projects. (Refer to page 27, section C.3-4.2.)
to. <?°$AB No. _i , Page 3
The Green Industry Council also had the following comments:
7. Zone 1 % Limitation ~ The limitation on "Zone 1 (Lush)" landscaping of 20%
for water conservation purposes is arbitrary and cannot be supported by scientific
data.
Discussion: After discussions with the Green Industry Council, the California
Association of Nurserymen, and the American Society of Landscape Architects,
and review of scientific data, the consensus is that the strict limitation of "Zone
1 (Lush)" landscaping should be replaced with an evaluation on a project by
project basis. The reason is that certain projects may have specific conditions
(i.e., large areas of shade between buildings) that can accommodate "Zone 1"
plants without excessive water being required.
Action: The 20% limitation on "Zone 1" plants has been eliminated (refer to
page 28, section C.3-4.5) and replaced with the requirement that the
appropriateness of areas of "Zone 1" planting be justified within the "Water
Conservation Plan." (Refer to page 8, section B.5-1). The "Water Conservation
Plan" is required on all projects to outline water conservation measures
proposed.
Staff has added another water conserving design requirement. Because the data has
indicated that many herbaceous ground covers require almost as much water as "warm
season grass," staff added the requirement that 60% of ground cover areas be planted
with "woody shrubs" over the herbaceous ground cover. "Woody shrubs" use less water
than the ground cover and will eventually grow over and replace the "herbaceous ground
cover." (Refer to page 28, section C.3-4.6).
Finally, there were several minor technical changes made as a result of concerns
expressed by the American Society of Landscape Architects and other interested
organizations, and those changes have been noted by asterisks(*) and cross-outs within
the text of the attached Landscape Manual (Exhibit 6).

FISCAL IMPACT;
The Planning Department currently contracts consulting landscape plan check services.
Development applicants pay a plan check fee that pays for this service. It is not
anticipated that the revisions to the Landscape Manual will require any more plan check
time than currently exists.
After City Council approval of the contents of the Landscape Manual, staff will utilize
the services of a graphic artist to enhance the layout of the Manual, add additional
graphics, and prepare the document for printing. Cost for the graphic artist services is
estimated at $6,700. Funds are available in the Advanced Park Planning Account No.

Requirements and Ordinance Nor)S-)3t-| deleting the word "guidelines" from Title 11,
Chapter 11.06, Section 11.06.025 of the Municipal Code.
ITEM DISCUSSION:
In 1983, the City Council adopted the Landscape Guidelines Manual. This manual
outlines standards and guidelines to be followed by developers and landscape designers
in preparing plans for approval by the City.
In response to the need to incorporate new ideas and address recent issues related to
landscaping, staff has revised the Landscape Manual (Exhibit 2).
During the revision process, staff contacted various governmental agencies,
professional organizations, and academic institutions throughout San Diego County as
well as the State for input into the document. A draft manual was prepared and
circulated to City departments and to several organizations for comments.
Major revisions to the manual include:
1. Strengthening the document - eliminating the term "Guidelines" from the
title and creating more specific requirements (vs. suggestions).
2. Adding a "Water Conservation Section" - requiring water saving irrigation
techniques and limiting high water use plants (including lawns).
3. Revised the "Streetscape Themes" - coordinating landscape "themes"
along major arterial roads with other City documents and existing
conditions and calling out specific shrub types to be planted in the
medians.
4. Updating Technical Standards - using current landscape industry
technology.
On September 17, the Parks and Recreation Commission recommended approval of the
Landscape Manual with the following suggestions:
EXHIBIT 3
c£
AB No. l*i fr?7 Page 1
Suggestion #1: Eliminate the term "Open Space" from the "Environmental
Resource/Open Space Section."
Action Taken: After consulting with the Planning Department, the entire section
has been eliminated due to pending future open space issues to
be studied (see pages 9 and 29 of the Manual).
Suggestion #2: Clarify that both public and private recreation areas are exempt
from the turf limitation.
Action Taken: Wording has been clarified (see pages 27, C.3-4.2).
Suggestion #3: Research City policy on "shake roofs" adjacent to high fire hazard
areas and possibly include within the "Fire Protection Section" of
the Landscape Manual.
Action Taken: The Fire Department has clarified that fire-proof roof materials
are already required through the building code for all structures
within the City.
On October 3, the Water Commission recommended approval of the Landscape Manual
with the following suggestions:
Suggestion: Revise the wording "Projects MAY be required, at the
discretion of the City, to be designed to utilize reclaimed
water" to read "Projects SHALL be required ... to utilize
reclaimed water.
Action Taken: Wording has been so revised (see page 27, C.3-5.1).
FISCAL IMPACT:
The Planning Department currently contracts consulting landscape plan check services.
Development applicants pay a plan check fee that pays for this service. It is not
anticipated that the revisions to the Landscape Manual will require any more plan
check time than currently exists.
After City Council approval of the contents of the Landscape Manual, staff will utilize
the services of a graphic artist to enhance the layout of manual, add additional
graphics, and prepare the document for printing. Cost for the graphic artist services
is estimated at $6,700. Funds are available in the Advanced Park Planning Account

TURF LIMITATION
ALTERNATIVES AND EVALUATION
NOTE: Percentages are turf allowed as percentage of total landscaped area.
ALTERNATIVE #1 - "CARLSBAD ORIGINAL DRAFT1
(as presented to City Council on 10/16)
ALL PROJECTS 10% (cool season grass)
(residential, commercial/industrial) 15% (warm season grass)
Exemptions: Recreational areas over 10,000 square feet.
Remarks:
1. Not favored by the Green Industry Council because of the strict percentage
limitations.
ALTERNATIVE #2 - "COUNTY MODEL"
(recommended by the County Technical Advisory Committee working on the "Water
Conservation Ordinance")
ALL PROJECTS 15% (cool season grass)
(residential, commercial/industrial) no restriction (warm season grass)
Exemptions: Limitation applies to "decorative turf" only.
Remarks:
1. This alternative is favored by the Green Industry Council because there is no
limitation on "warm season grasses." They feel this is justified because studies
indicate "warm season grasses" do not use significantly more water than some ground
covers.
2. Staff does not favor this alternative because there is no limitation whatsoever on
"warm season grasses" (i.e., a development could have miles of turf throughout the
project.) Staff feels some limitation is warranted because:
a. Although under scientific study plots, "warm season grass" may not use
significantly more water than ground cover, the tendency is for maintenance
people to water grass more often than ground cover and to water "warm
season grass" the same as "cool season grass."
b. Grasses, both "warm and cool season" require relatively high amounts of
energy to sustain them (fertilizer, mowing, etc.).
EXHIBIT 4
c. It is a common practice to "overseed" "warm season grass" with "cool season
grass" in the winter. This would create an increased water demand. The City
would have no control over the practice of "overseeding."
d. Public perception of large areas of turf ("warm or cool season") is the same
in terms of water conservation awareness.
3. Staff would have difficulty determining what is "decorative turf as it relates to
limiting "cool season grass." It is too subjective and will be open for interpretation.
ALTERNATIVE #3 - "PER PROJECT TYPE" - STAFF EBCOMMEIC^ATiOH
(relates turf allowance to type of project)
A. RESIDENTIAL (per general plan designation)
1. RH (high density) 50% (cool season grass)
OR 80% (warm season grass)
2. RMH (medium high) 30% (cool season grass)
RML (medium low) OR 50% (warm season grass)
3. RM (medium density) 15% (cool season grass)
RL (low density) OR 25% (warm season grass)
Exemptions: Common recreation areas regardless of size.
B. COMMERCIAL/INDUSTRIAL 10% (cool season grass)
OR 15% (warm season grass)
Remarks:
1. Staff favors this alternative because:
a. allows turf where it is most used
b. relatively less subjective to interpret and enforce
c. encourages "warm season grass" over "cool season grass."
2. The representative of the American Society of Landscape Architects feels this is a
responsible approach.
3. The "Green Industry Council" representative does not favor this alternative because
it restricts "warm season grass."
SCIENTIFIC DATA ON
TURF WATER
AND ENERGY CONSUMPTION
Attached are scientific studies with data indicating water and energy
requirements of turf in general and "warm" vs. "cool season grasses". Staff has
analyzed the data and provided the following summary and interpretation.
Summary of Data
1. "Cool season grasses" use ± 30% more water than "warm season grasses".
2. "Cool season grasses" use ± 60% more water than ornamental ground covers
(i.e., ivy, gazania).
3. "Warm season grass" use ± 20% more than ornamental ground covers.
4. Turf in general uses ± 2.5 times more energy to maintain than other
plantings (i.e., gas engines for mowing, fertilization, etc).
5. Trees and shrubs provide ± 7.2 times more oxygen and ± 6.6 times greater
carbon storage (exhaust).
Staff's Interpretation of Data
1. Because of the relatively greater water consumption and less environmental
benefits of turf (i.e., oxygen production and carbon storage), some
limitation of both warm season and cool season grass are warranted.
2. The amount of "cool season grass" allowed should be 30% less than the
amount of warm season grass allowed.

COMPARISON OF RELATIVE VALUES OF TURF GRASS AND
TREES, SHRUBS, GROUNDCOVERS AS LANDSCAPE
TREATMENTS.
Prepared by Glen Schmidt, ASLA - August 1990
The following is an attempt to determine relative costs and values
of turf grass versus other landscape treatments taking into
consideration relative benefits and costs.
Information was derived from the City of Irvine's "Sustainable
Landscape Manual" 1990 which includes studies from: Victor
Gibeault, U.C. Riverside, information adapted by Rod Perry Calif. Poly
Pomona from Lieth, Helmut and Robert H. Whittaker; 1975; "Primary
Productivity of the Biosphere", and Rod Perry Calif. Poly Pomona /
Rob Thayer, U.C. Davis.
The following comparison includes cool and warm season turf
grasses versus typical shrub beds that include: Mixed Temperate
Landscape and Subtropical Landscape as defined in the "Sustainable
Landscape Manual", this includes 5-8 species of trees, 12-15
species of shrubs, and 2-3 ground covers.
WATER CONSUMPTION
Cool season turf used approximately 1.6 more water than typical
tree and shrub beds.
Warm season turf used approximately 1.2 more water than typical
tree and shrub beds.
Verified by Dave Shaw at U.C. Cooperative Extension who has
indicated groundcovers use up to .5 of ET, cool season turf .8 of ET,
Warm season turf .6 of ET.
ENERGY CONSUMPTION
Warm and Cool season turf used approximately 2.5 more energy for
installation and maintenance that typical tree and shrub beds.
Turfgrass energy consumption per year: 49,555,000 Btu's
Tree and shrub energy consumption per year: 20,056,000 Btu's
.'XEROX TELECOPIER 7010 ; 10- 4-90 10:45PM; CCITTOW 24070;«
10/04x90 ie.5; S 619 236 S792 sc, ~ >
ENVIRONMENTAL BENEFITS
Tree and shrub total oxygen production is 7.2 greater than Warm and
Cool season turf.
Tree and shrub total carbon storage is 6.6 greater than Warm and
Cool season turf.
Average environmental benefit from tree and shrubs is 6.9 greater
than wajm and cool season turf (average of 7.2 and 6.6).
Turfgrass oxygen production tons/acre: 5
(3-5 years of growth)
Tree and shrub oxygen production tons/acre: 36
(25 years of growth)
Turfgrass carbon storage tons/acre: 2.7
(3-5 years of growth)
Tree and shrub carbon storage tons/acre: 18
(25 years of growth)
TOTALS
COOL SEASON TURF VS. TREES AND SHRUBS
WATER CONSUMPTION 1.6 GREATER
ENERGY CONSUMPTION 2.5 GREATER
ENVIRONMENTAL BENEFIT 6.9 LESS
AVERAGE VALUE 3.66 e 27%
WARM SEASON TURF VS. TREES AND SHRUBS
WATER CONSUMPTION 1.2 GREATER
ENERGY CONSUMPTION 2.5 GREATER
ENVIRONMENTAL BENEFIT 6.9 LESS
AVERAGE VALUE 3.53 = 28%
A fair limitation of turf species then without a visual or
cost value associated with It would be a total of 25% to
30% of landscaped area.
III. WATER USE OF TURFGRASS AND LANDSCAPE PLANT MATERIALS
Studies of pasture water use and weather data have led to the development of
relationships for predicting water use, or evapot ranspirat ion (FT), from cl im.it ic
factors. Historical or average values of reference evapotranspiration (Flo) have
been determined for most areas of California from evaporation, solar radiation,
and temperature records. Historical ETo values for locations in San Diego County
are given in the TURFIMP computer program and in Appendix C.
The historical information is of great value in predicting plant water use for
determining generalized irrigation schedules. Real time ETo' ini 01 rn.'ii :ion f i om
the California Irrigation Management Information System (CIMIS) is useful for
weekly updating of the generalized irrigation schedule. Detailed CI.MIS
information can be obtained be contacting the California Department of H-iU'i-
Resources, Office of Water Conservation, P.O. Box 388, Sacramento, CA 9-Jl'Jb-
0001.
In the San Diego Region, a telephone recording gives average daily Flo wilnes
for the past week for the C1MIS weather stations at San Diego, Fccondido,
Oceanside, and Temecula. The recording is updated every Wednesday or Thursday.
Real Time CIMIS Information for San Diego County: 1-800-336-3023
ETo can be used to estimate the water use of different plant materials by
multiplying by a correction factor called a crop coefficient or Kc value. This
relationship is:
ETo x Kc = Crop El
The Kc values in Table 1 have been determined through University of California
research projects and are good starting points for determining plant water use
and irrigation schedules. "Normal" Revalues are given for actively growing plant
material and "Minimum" Kc values are given for acceptable plant quality tinder
minimum irrigation. It may be necessary for landscape water managers to adjust
Kc values depending on site conditions and the amount of water stress desired.
For example, the Kc may need to be adjusted for plantings subjected to partial
shade from a building, excessive wind, or advective heat from a street ot parking
lot.

The Manual is broken down into 4 distinct areas:
• Submittals (Section II and III)
• Policies and Requirements (Section IV)
• Installation, Bonding and Maintenance Requirements (Section V)
• Appendix
The SUBMITTALS sections tell the applicant:
1. What types of submittals are required.
2. What the intent of requiring the submittal is.
3. Who shall prepare the submittal.
4. What the graphic format shall be.
5. What the contents shall be.
The POLICIES AND REQUIREMENTS sections tell the applicant.
1. What the policies are of the City of Carlsbad related to different areas of
landscape design.
2. What other related sections of the Manual apply.
3. What are the specific requirements that relate to the different areas of
landscape design.
INTER-RELATIONSHIP
The policies and requirements of the different sections may be inter-related, that is
they may apply to more than one section although only stated once.
For example, one of the policy statements found in the Water Conservation Policies
and Requirements section states "Carlsbad is in a naturally semi-arid region. The
landscape ethic should be towards designing and maintaining landscape systems
compatible with the natural environment." This policy also applies to all other
sections as well.
As a second example, the requirement that "pressure regulating device shall be used
where the static pressure at the point of connection exceeds 80 pounds per square
inch" is found in the General Irrigation Policies and Requirements. However, this
requirement also pertains to the Erosion Control/Slope Revegetation and the
Streetscape Program sections where applicable.
Therefore, the users of this manual must pay close attention to the "Other
Applicable Sections" paragraph at the beginning of each section as well as cross
references throughout the text.
D. CONFLICTS WITH OTHER DOCUMENTS
If conflicts arise between this manual and other governing documents, the most
stringent and/or recent shall apply.
E. MINIMUM REQUIREMENTS
The policies and requirements within this manual are minimum standards. Projects
are encouraged to exceed these standards whenever appropriate.
F. VARIANCES AND ALTERNATIVE COMPLIANCE
Variances may be granted from the policies and requirements of this manual by the
City from time to time if undue hardships or special circumstances make the
variance request necessary.
Variance procedures shall conform to City policy related to the specific modifications
being requested at the time of the request.
Where the literal interpretation and enforcement of the requirements of this
document would result in practical difficulties, environmental degradation, or results
inconsistent with the general purpose of this document, formal written request to
vary from these requirements shall be made to the Planning Director, City Engineer,
or Parks and Recreation Director. The City department to which this written
request is made will depend on the type of variance requested and which
department is responsible to oversee the requirement for which the variance is being
sought.
Before any variance is granted, the following findings must be made:
1. That there are extraordinary or unusual circumstances or conditions
applicable to the project necessitating a variance from the requirements of
this document.
2. That the proposed variance will not be detrimental to the health, safety, and
general welfare of persons residing, working, playing, or traveling through
the area and will not adversely impact other property in the vicinity.
3. That the proposed variance meets the intent of the policies and requirements
of this document.
The written request for variance shall describe the variance and justification for such
variance and address how each of the findings above can be made.
If, in the opinion of the Planning Director, City Engineer, or Parks and Recreation
Director, the variance is justified and the findings can be made to support the
variance, the variance may be issued by the applicable City department without a
public hearing.
City may decide, at their discretion, to put the variance before the Planning
Commission and/or Parks and Recreation Commission for public hearing if it is felt
that the variance is of such a nature that Commission and public review is
warranted.

elements of Carlsbad.
G.I-2 Landscaping shall be designed toward a goal of providing a pleasing and safe
vehicular and pedestrian experience.
G.I-3 The City is establishing these policies and requirements to ensure that
sidewalks and other pedestrian walkways are safe for pedestrian use and that
crackling or buckling of sidewalks and other pedestrian walkways will be
eliminated or minimized. The City is not a guarantor of perfectly flat
sidewalks and can only maintain them within its reasonable budgetary
powers. However, these guidelines are being established to prevent, to the
maximum extent possible, tree roots from invading, disrupting or destroying
City sidewalks. Although it remains the property owner's duty to notify the
City if a problem arises and liability to third persons may need to be
judicially determined, it is hoped that with the City's routine inspection and
maintenance "program and these policies and requirements, such incidents
will be minimized.

ARTERIAL ROADS
CONCEPT
These roadways will carry large volumes of traffic into and through Carlsbad.
They provide the means for an initial and repeated exposure to the City's
physical setting. Their visual corridors play an important role in developing
an image of Carlsbad. This image creates an enduring impression to aid in
the City's sense of place and community pride.
Specific criteria has been set for the landscaping along the prime and major
arterial roadways. These routes will each have individual streetscape themes
creating a recognizable identity for each particular thoroughfare or segment
of thoroughfare. The themes are based on the character or heritage of that
specific area of Carlsbad.
TREE TYPES
The specific trees creating a streetscape theme have been pre-selected by the
City. Each theme shall be made up of four (4) types of trees: "Theme",
"Support", "Median", and "Project Identity/Accent Trees".
Median Island Trees - These trees shall be installed as part
of the required street improvements.
Theme Trees - These trees set the overall character of
the streetscape and are located along the roadside but
outside the right-of-way. (See G.3-1.2-3.)
Support Trees - These trees were selected to complement
the theme tree. Select trees from those listed which
fit the project site conditions.
Project Identity/Accent Trees - These trees are not
pre-selected, rather the applicant can choose the
best tree for their project and submit it for Gty approval.

PLANTING ZONES
Zone One - Lush Landscape
1. Criteria
a. Zone One should be utilized only in areas of a development which
require a lush green landscape such as areas of high use or visual
importance.
b. The plantings require an intensive maintenance operation to produce
the desired appearance.
c. This Zone's anticipated appearance relies on large amounts of
irrigation. Annual amounts for a healthy, mature landscape are
estimated at over thirty (30") inches of supplemental water annually.
2. Description
Zone One may be thought of as a traditional landscape, green, lush, and
flowering. Most plants used to produce this effect do not come from a semi-
arid type climate found in Southern California. These exotic plants require
large amounts of water and intensive maintenance.
Although Carlsbad has a mild temperate climate, it remains a semi-arid
region, characterized by poor, infertile soil. Natural lush landscapes are
found within our area, but only in very limited micro-climates whose special
environment can produce the requirements to support this types of
landscape.
This natural pattern of limited lush landscapes should act as a guide for Zone
One's use. These lush landscapes should be utilized for areas of intensive use
or as a sensory rich setting in areas visible and important to the majority of
users, such as entries, courtyards, pedestrian ways, and recreation areas.
APPENDIX A

3. Zone One Plants - Typical species related to this zone might be:
- Azalea species
- Fatsia japonica
- Ferns - Asplenium; Blechnum
- Fuchsia
- Gardenia species
- Schefflera actinophylla
- Annual flower color
- Lawns
B. Zone Two - Refined Landscape
1. Criteria
a. Zone Two should have an unmanicured appearance, not unkept, but
rather a landscape designed to require less intensive types of
maintenance such as mowing, pruning, fertilizing, and watering.
Plant material whose appearance is not dependent on heavy watering
and maintenance care.
b. It stresses continually low maintenance by designed plant
combinations with matched growth requirements. This zone's water
requirements for a mature landscape is estimated between ten (10")
and thirty (30") inches of supplemental irrigation water annually.
2. Description
Zone Two attempts to reflect the natural constraints of Carlsbad's physical
environment. It substitutes for a historically disproportionate use of Zone
One's "traditional landscape". Its design and selection of materials promote
less maintenance and lower water requirements.
3. Zone Two Plants - Typical species related to this zone might be:
- Pittosporum tobira "Wheeleri"
- Raphiolepis indica
-Hebe
- Agapanthus
- Psidium guajava
- Frageria chiloensis
A.2
C. Zone Three - Naturalizing Landscape
1. Criteria
a. This zone will be planted in low use areas whose visual character will
not have a refined appearance. It will have a naturalized appearance
similar to areas of native vegetation and may in fact contain native
species.
b. It will have the ability to "naturalize" once it has been established. Its
estimated supplemental water requirement is below ten (10") inches
annually.
2. Description
Zone Three will be primarily used to create a more natural looking area, such
as slopes, periphery areas, and areas of projects where disturbed grounds
may need to blend into vegetation. The success of this landscape is directly
related to its ability to become self-sufficient within a prescribed period of
time. A self-sufficient landscape, Zone Three is capable of sustaining itself
as an effective landscape on very limited water and remain healthy. Few
newly planted juvenile plants are "drought tolerant", but they develop the
ability to adapt to cycles of dry periods once their root systems have
developed and have matured and adapted to the site conditions.
3. Zone Three Plants - Typical species related to this zone might be:
- Acacia redolens
- Mimulus species
- Ribes speciosum
- Ceanothus
- Cassia
- Lantana camara
- Mahonia
- Baccharis pilularis
- Rosmarinus officinalis
D. Zone Four - Native Landscape
1. Criteria
a. Zone Four is an area of existing vegetation whose native character
shall remain with very little modification.
A.3
b. It is planned for low-level active use, which is compatible with the
area's natural character.
c. In this zone, no water is required. The use of irrigation can adversely
affect many plants found in this zone. Introduced plants should be
watered individually.
2. Description
Zone four consists of natural vegetation, native or naturalized, in which there
is no or very little disturbance from site improvements. An area may be
planned as a Zone Four landscape to preserve its physical features, its
qualities as a natural ecosystem, wildlife habitat, or as open space. These
qualities may be used to provide passive recreational opportunities, possibly
linked by hiking trails.
Zone Four will require a minimal level of upkeep. Its maintenance program
will consist of periodic control of debris and minor clearing and/or pruning
for fire protection and removal of non-native species. Retained in their
natural non-irrigated condition, these areas will remain relatively dry. Due
to this characteristic, a "Fire Protection Program" may be required.
