PC Res 2865RESOLUTION NO. 2865 RESOLUTION OF THE PLANNING COMMISSION OF THE CITY OF CAMPBELL RECOMMENDING THE CITY COUNCIL TO ADOPT THE ATrACHED REVISED WATER EFFICIENT LANDSCAPE GUIDELINES. WHEREAS, the City Council adopted by minute action the Water Efficient Landscape Standards on September 18, 1990. WHEREAS, the California State Legislature passed AB325, the Water Conservation in Landscaping Act on September 20, 1990. WHEREAS, AB325 requires cities and counties to pass a water conservation ordinance or issue findings that no ordinance is necessary by January 1, 1993 or be subject to the State Model Ordinance. WHEREAS, the City of Campbell had not passed the Water Efficient Landscape Standards by resolution or ordinance by January 1, 1993 and is therefore subject to the State Model Ordinance. WHEREAS, the Water Efficient Landscape Standards have been revised to comply with AB325. 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: Ayes: Commissioners Alne, Wilkinson, Meyer-Kennedy, Perrine, Akridge, Lindstrom, Fox Noes: None Absent: None Abstain: None I. Alne, Chairperson Ste~e Piasecki, Secretary 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.
