NOW THEREFORE BE IT RESOLVED, the Planning Commission
recommends that the City Council adopt by resolution the attached revised
Water Efficient Landscape Guidelines and approve a text amendment to
Section 21.57.040 part D of the City's Zoning Ordinance to read "Landscaping
shall be consistent with Campbell's Water Efficient Landscape Guidelines."
ADOPTED AND PASSED this 13th day of July, 1993 by the following roll call
vote:

WATER EFFICIENT LANDSCAPE
GUIDELINES
CITY OF CAMPBELL
Adopted by City Council
Resolution #.
on
APPLICABILITY
These guidelines shall be used to evaluate landscaping plans for all
new construction projects including:
industrial
commercial
institutional
multi-family
Planned Development Zones ( including single-family)
renovation projects
o
Exempt projects include but are not limited to single family houses
not in Planned Development Zones, ecological restoration projects,
and historical structures.
PLANT MATERIAL AND DESIGN
Water conserving plant material shall be installed in all landscaped
areas. Water conserving plant material shall mean any plant
material included in the city's approved list of water conserving
plant material. Deviations from the list may be approved by the
Director of Community Development.
e
Turf, annuals, decorative pots, and water bodies shall be limited to
30% of the landscaped area. Turf areas required as part of a
streetscape treatment are exempt from the 30% limitation.
o
Annual color, turf and water bodies shall be limited to areas of high
visibility and/or high pedestrian use.
o
Turf shall be of drought-resistant variety such as Double Dwarf
(Bonsai) Fescue, Medallion, Champion or other approved
equivalent.
Turf shall not be planted on slopes greater than 10:1 or in planting
areas less than 8 feet wide.
o
Berms and excessively sloped landscaped areas are discouraged.
Where slope areas are over 4:1, evaluation for retaining walls shall
be required.
EXISTING PLANT MATERIAL
The applicant shall prepare an accurate survey of existing trees
(with a trunk diameter greater than 4") for all new projects,
including the location, species, trunk diameter, and drip line.
Developers of new projects shall make every effort to integrate
existing healthy trees with trunk diameters exceeding 4" (measured
4' above natural grade) into the project's site design. Where
integration is not possible or desirable due to location, tree type, or
other reason, the developer shall develop a replacement planting
program.
Existing trees shall be replaced with 24" box trees according to the
following replacement ratios:
Trunk diameter of removed tree
(measured 4' above natural grade)
<12"
12' - 24"
>24"
Replacement ratio
1 tree for each tree removed
2 trees for each tree removed
3 trees for each tree removed
If the site layout can not accommodate the number of trees required,
the Community Development Director can approve a reduction in
the replacement ratio.
The replanting program is subject to review and approval by the
Community Development Department prior to issuance of a
building permit. The program should include a map with the
location and species of the proposed replacement trees.
o
Trees or plants to be retained shall be protected during construction
with temporary fencing (see detail labelled 'Protection of Existing
Tree"). The natural grades within the drip line of the existing tree
shall not be altered unless a tree surgeon or landscape architect
verifies the health of the trees will not be compromised. A tree
protection plan shall be approved by the Community Development
Department prior to issuance of building permits.
o
Special consideration shall be given to oak trees. Oak trees are
extremely sensitive and can be easily damaged. No irrigation shall
be installed within the drip line of an existing oak tree or irrigation
allowed to encroach into this area.
o
Stream and creek beds are extremely sensitive and should be
identified and preserved. Plants that are found in the riparian
corridor shall be incorporated into the plant list for the project.
IRRIGATION
All landscaped plans shall include an automatic irrigation system
and shall be equipped with a time controller capable of percent
adjustment, multiple programming, and rain sensor. Controllers
must have multiple cycle start capacity and a flexible calendar
program.
Plants shall be grouped and irrigated with separate valves and
circuits according to water use and sun exposure.
o
Accessible check valves are required where elevation differential
may cause low head drainage.
o
Drip or bubbler irrigation systems with deep watering pipes are
required for trees.
o
Sprinkler heads must have matched precipitation rates within each
control valve circuit.
6. Sprinklers shall be placed to achieve head to head coverage.
o
All irrigation systems shall have a water purveyor approved back
flow prevention device installed to meet current code
requirements.
ge
A complete irrigation schedule shall be provided along with the
irrigation plans. Information shall include: evapotranspiration
rates, run times and dates, and total water usage for the year.
9. Watering shall only occur between the hours of 10 pm and 6 am.
10.
For grade changes over 10%, the irrigation system shall be divided
into separate systems - one for the top of the slope, and one for the
bottom of the slope.
SOILS
1.
Agricultural suitability and soil fertility tests shall be required and
shall be submitted with landscape plans.
o
o
The soil shall be amended according to the soil analysis and plant
material shall be appropriate for the predominant soil type.
A minimum of two inches of mulch shall be added in all non-turf
areas to the soil surface after planting.
Non-porous materials shall not be placed under living plant
materials or mulched areas.
DECORATIVE USE OF WATER
Water bodies that are part of the landscaping are discouraged
(unless the body of water is an integral part of the operations of the
new development) and shall be subject to review for the efficient
use and reuse of water.
2. All water bodies will have impermeable linings.
ge
Except for swimming pools and spas, only recycled or reclaimed
water may be used.
IMPLEMENTATION
The landscape standards will be implemented using existing staff
and resources and within the existing development review process.
City staff will rely upon the landscape advisor to review the
preliminary and final landscape plans for compliance with these
standards.
o
Building plans will be checked at the building permit level to
ensure compatibility with the approved landscape plans. Landscape
plans will include a planting plan, an irrigation plan, and
specifications and details.
Staff will conduct a site observation in conjunction with normal
landscape review to ensure compliance with the approved plans
prior to issuance of occupancy permits.
