CHAPTER 17
32 WATER EFFICIENT LANDSCAPE DESIGN
§ 17.32.010 Purpose.
Landscapes that are designed, installed, managed and maintained with the watershed based approach can improve California's environmental conditions and provide benefits and realize sustainability goals. Such landscapes will make the urban environment resilient in the face of climatic extremes. The following water efficient landscape standards are designed to assist landscape architects, irrigation designers, contractors, planners and the public in the selection of plant materials and irrigation methods that result in more water efficient and water conscious landscaping throughout the city. The purpose of this chapter is to:
A.
Promote high quality, water efficient landscaping, water use management and water conservation through the use of water efficient landscaping, wise use of turf areas and appropriate use of irrigation technology and management.
B.
Create the conditions to support life in the soil by reducing compaction, incorporating organic matter that increases water retention, and promoting productive plant growth that leads to more carbon storage, oxygen production, shade, habitat and esthetic benefits.
C.
Minimize energy use by reducing irrigation water requirements, reducing reliance on petroleum based fertilizers and pesticides, and planting climate appropriate shade trees in urban areas.
D.
Conserve water by capturing and reusing rainwater and graywater wherever possible and selecting climate appropriate plants that need minimal supplemental water after establishment.
E.
Protect air and water quality by reducing power equipment use and landfill disposal trips, selecting recycled and locally sourced materials, and using compost, mulch and efficient irrigation equipment to prevent erosion.
F.
Protect existing habitat and creating new habitat by choosing local native plants, climate adapted non-invasive plants and avoiding invasive plants. Utilizing integrated pest management with least toxic methods as the first course of action.
G.
Promote the values and benefits of landscape practices that integrate and go beyond the conservation and efficient use of water.
H.
Provide for provisions for water management practices and water waste prevention.
I.
Establish a structure for planning, designing, installing, maintaining, and managing water efficient landscapes in new construction and rehabilitated projects by encouraging the use of a watershed approach that requires cross-sector collaboration of industry, government and property owners to achieve the many benefits possible.
J.
Reduce landscape water demands without sacrificing landscape quality or quantity.
K.
Retain flexibility and encourage creativity through appropriate design.
L.
Eliminate water waste from overspray and/or runoff.
M.
Promote water conservation through public awareness.

ETo is expressed in inches per day, month, or year and is an estimate of the evapotranspiration of a large field of four- to seven-inch tall, cool season turf that is well watered. Reference evapotranspiration is used as the basis of determining the maximum allowable water allowance so that regional differences in climate can be accommodated. The annual ETo for Temecula is provided in the Reference Evapotranspiration (ETo) Table of Appendix C of the California Department of Water Resources' Model Water Efficiency Landscape Ordinance, as may be amended from time to time.
means any re-landscaping project that requires a permit, plan check, or design review, meets the requirements of Section 17.32.030, and the rehabilitated landscape area is equal to or greater than two thousand five hundred square feet.

The surface area of water features is included in the high water use hydrozone of the landscape area. Constructed wetlands used for on-site wastewater treatment or stormwater best management practices that are not irrigated and used solely for water treatment or stormwater retention are not water features and therefore, are not subject to the water budget calculation.
means a landscape with a WUCOLS plant factor of 0.7 or greater.
means the publication entitled "Water Use Classification of Landscape Species" published by the U.C. Cooperative Extension and the Department of Water Resources 2014.

G.
A shallow swale shall be designed at the toe of all berms which are adjacent to sidewalks or other impervious surfaces to "catch" any runoff. This will help prevent weathering of pavement. If overhead spray irrigation is used for bermed areas, sprinkler heads shall be placed at the toe of the berm, so as to water from the bottom up.

3.
The protection, preservation and enhancement of native species and natural areas are required where feasible.
4.

In areas with groundcover planted from flats, the mulch depth shall be no less than one and one-half inches. The mulching should be in the form of shredded bark, bark chips of varying sizes, or other similar materials. The size and type of mulch used should allow for moisture to pass through the surface, thus providing permeability and reduced erosion, particularly on slopes. Nonporous material shall not be placed under mulch.
5.
Mulch stabilizer products shall be used on slopes when a binding agent is deemed necessary to hold the organic mulch in place. A stabilizing mulch product such as hydraulic mulch, jute mesh, and erosion control blankets shall be used only as a temporary erosion control.
6.
Organic mulch materials made from recycled or post-consumer shall take precedence over inorganic materials or virgin forest products unless the recycled post-consumer product is not locally available. Organic mulches are not required where prohibited by fuel modification plans as determined by the city's fire department.
Inorganic mulch groundcover, such as gravel or crushed rock, should be used only as an accent material. No more than fifteen percent of the total landscape area should consist of such inorganic mulch groundcover, and, if used, the materials should be used in combination with live plants.

§ 17.32.070 Water efficient landscape worksheet.
A project applicant shall complete the water efficient landscape worksheet in Appendix A in Section 17.32.200, which contains information on the plant factor, irrigation method, irrigation efficiency, and areas associated with each hydrozone. Calculations are then made to show that the evapotranspiration adjustment factor (ETAF) for the landscape project does not exceed a factor of 0.55 for residential areas and 0.45 for nonresidential areas, exclusive of special landscape areas. The ETAF for a landscape project is based on the plant factors and irrigation methods selected. The maximum applied water allowance is calculated based on the maximum ETAF allowed (0.55 for residential areas and 0.45 for nonresidential areas) and expressed as annual gallons required. The estimated total water use (ETWU) is calculated based on the plants used and irrigation method selected for the landscape design. ETWU must be below the MAWA.
