Water conservation reduces demand on groundwater and surface water supplies, saves energy, inhibits salt-water intrusion and conserves aquatic resources. Sustainable landscapes benefit ecosystems, enhance soil and scenic resources, minimize energy use and reduce greenhouse gas emissions. The purposes of this chapter are to:

(A)    Conserve water by setting a maximum applied water allowance as an upper limit for water use and reducing water use to the lowest practical amount;

(B)    Promote sustainability and mitigate climate change in new landscaping projects by installing native plants and habitat enhancements, avoiding invasive plants, improving soils, minimizing stormwater runoff and providing shade;

(C)    Improve the efficiency of existing landscaping;

(D)    Promote rainwater capture and graywater use; and

(E)    Implement the 2015 California Model Water Efficient Landscape Ordinance. [Ord. 5218 § 1, 2016; Ord. 5148 § 1, 2013].

(3)    Plants shall be grouped together in hydrozones with distinct plant factors and, as applicable, slope, sun exposure and soil conditions, irrigated with separate valves. No plant factor shall exceed its hydrozone level, based on WUCOLS or other documentation accepted by the Director. All plants in a special landscape area will be considered to have a plant factor of 100 percent; any lower water-use plants in special landscape areas are encouraged to be on separate valves.

(4)    To encourage the efficient use of water, at least one of the following methods shall be utilized to plan hydrozones:

(a)    The Sunset Western Climate Zone System, taking into account temperature, humidity, elevation, terrain, latitude, and varying degrees of continental and marine influence on local climate.

(b)    Landscape Plants for California Gardens, for landscapes and hydrozones segregating climate tolerant and summer-dry plants.

(c)    Plant placement based on solar orientation, to maximize summer shade and winter solar gain.

(5)    Water in artificial pools and fountains shall be recirculated.

(6)    Where subject to this chapter, swimming pools are required to remain covered when not in use, in order to reduce evaporation.

(7)    The use of invasive plants, such as those listed by WUCOLS or the California Invasive Plant Council, within any subject landscape, is strongly discouraged and may be restricted or prohibited by the Director.

(8)    Landscape associated with one- to two-unit residential development is not required to include a fixed irrigation system unless the Director finds it warranted by project-specific circumstances.

(D)    Irrigation Design.

(1)    Irrigation systems shall be designed to avoid runoff, overspray, low-head drainage and other conditions where water may flow onto non-target areas or plants, walks, roadways, structures or adjacent property.

(2)    Irrigation systems shall be designed, maintained and managed to meet or exceed an average landscape irrigation efficiency of 75 percent for overhead and 81 percent for drip.

(3)    Differing hydrozones shall be irrigated with separate valves.

(4)    Irrigated areas less than 10 feet wide shall be irrigated with subsurface or low volume irrigation.

(5)    Overhead spray nozzles shall have a precipitation rate of no more than one inch per hour.

(7)    Overhead sprinkler systems shall not be permitted within 24 inches of any nonpermeable surface, including driveways and sidewalks, unless strict compliance with subsection (D)(1) of this section is demonstrated on plans, maintained and confirmed by audit. Only low volume irrigation shall be allowed within the 24-inch setback, if planted.

(8)    In mulched planting areas, the use of low volume irrigation is required to maximize water infiltration into the root zone.

(9)    Trees shall be watered using separate irrigation circuits.

(10)    Slopes greater than 25 percent shall not be irrigated with an application rate exceeding 0.75 inches per hour. This restriction may be modified if the landscape designer specifies an alternative design or technology and clearly demonstrates no runoff or erosion will occur.

(11)    Where available and economically feasible, recycled water shall be used to irrigate landscapes.

(E)    Irrigation Equipment.

(1)    Irrigation systems shall have self-adjusting controllers, based on evapotranspiration (weather station data) or soil-moisture, and shall be equipped with rain-sensing devices to prevent irrigation during rainy weather. Irrigation controllers shall be of a type which does not lose programming data in the event the primary power source is interrupted. In residential development projects utilizing 75 percent low-water-use plants and no turf, the Director may waive the requirement to install a self-adjusting controller.

(2)    A pressure regulator shall be installed if working pressure at the water meter exceeds 80 psi.

(3)    The irrigation system shall include a flow sensor with automatic shutoff to prevent excess flow created by system damage or malfunction, and also a readily accessible manual shut-off valve.

(4)    Backflow prevention devices shall be installed as required by the California Plumbing Code to protect the water supply from contamination by the irrigation system.

(5)    Anti-drain check valves shall be installed to prevent low-head drainage.

(6)    Sprinkler heads shall have matched precipitation rates within each control circuit valve and shall be selected for proper coverage and precipitation rate.

(7)    Swing joints or other riser protection components are required on all risers located in high traffic areas.

(F)    Soil Management, Preparation, and Mulching.

(1)    Soil in nontemporary irrigation areas shall be prepared for planting by ripping and incorporating an organic amendment at the rate of six cubic yards per 1,000 square feet into the top six inches, or amended as indicated by a soil analysis report. Ripping shall not be required where soil amendments are applied directly to plant holes. Soil amendments shall not be required for:

(a)    Plant varieties for which soil amendments are harmful or counterproductive;

(b)    Soils with greater than six percent organic matter in the top six inches of soil; or

(c)    Landscapes where native plants adapted to site soils are used.

(2)    Organic mulch materials made from recycled or post-consumer materials shall be used instead of inorganic materials or virgin forest products unless the recycled or post-consumer organic products are not locally available.

(3)    Additional soil amendments shall be added as appropriate to address adverse factors such as high clay content, poor drainage, low nutrient content, high salt content or unfavorable pH, so that water application consistent with specified plant factors is sufficient to ensure healthy plant growth.

(4)    If a soils analysis is submitted pursuant to application requirements established by the Planning Director, the soil analysis report recommendations shall be implemented.

(5)    All exposed soil surfaces of non-turf areas within the landscape area must be mulched with a minimum three-inch layer of organic material, except for creeping or rooting groundcovers, direct seeding or other applications where mulch is contraindicated. To provide habitat for beneficial insects and other wildlife, up to five percent of the landscape area may be left without mulch.
