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.
N.
Implement
the requirements to meet the state of California Water Conservation
in Landscaping Act 2006 and the California Code of Regulations Title
23, Division 2, Chapter 2.7, and Executive Order B-29-15.

plant factor range for low water use plants is 0.01 to 0.3, the plant
factor for moderate water use plants is 0.4 to 0.6 and the plant factor
for high water use plants is 0.7 to 1.0. Plant factors cited in this

determining the maximum allowable water allowance so that regional
differences in climate can be accommodated. The annual ETo for Temecula
is 56.7.

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.

H.
If
the area proposed for development is improved and is not scheduled
for development within six months of the completion of the previous

prohibited in street medians.
9.
Artificial/synthetic
turf is not a permitted plant material in commercial, industrial,
or mixed-use zones and/or multifamily projects. Green artificial turf
may be permitted in commercial, industrial, and/or mixed-use zones
or multifamily projects when utilized for bona fide recreational facilities
such as a sports field. Green artificial/synthetic turf is a permitted
non-plant material for single-family homes when used in place of a
lawn or other landscaped area of the home.
L.
Protective
tree grates shall be provided for trees planted in pedestrian areas.

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.
Stabilizing
mulching products shall be used on slopes.
6.
Organic
mulch materials made from recycled or post-consumer shall take precedence

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.

2.
All
water features shall be included in the high water use hydrozone and
temporarily irrigated areas shall be included in the low water use
hydrozone.
