WATER EFFICIENT LANDSCAPE DESIGN STANDARDS;
DECLARING THE URGENCY THEREOF; AND FINDING
THIS ORDINANCE IS EXEMPT FROM THE CALIFORNIA
ENVIRONMENTAL QUALITY ACT (CEQA) UNDER CEQA
GUIDELINES SECTION 15308, CLASS 8
THE CITY COUNCIL OF THE CITY OF TEMECULA DOES HEREBY ORDAIN
AS FOLLOWS:
Section 1. Findings. The City Council of the City of Temecula does hereby
find, determine and declare that:
A. On April 1, 2014, Governor Edmund G. Brown Jr. issued an executive
order to strengthen the state's ability to manage water and habitat effectively in drought
conditions and called on all Californians to redouble their efforts to conserve water. The
executive order finds that the continuous severe drought conditions present urgent
challenges across the state including water shortages in communities and for
agricultural production, increased wildfires, degraded habitat for fish and wildlife, threat
of saltwater contamination, and additional water scarcity if drought conditions continue
into 2015.
B. The executive order refers to the Governor's Proclamation No. 1-17-2014,
issued on January 17, 2014, declaring a State of Emergency to exist in California due to
severe drought conditions. The January Proclamation notes that the state is
experiencing record dry conditions, with 2014 projected to become the driest year on
record. Since January, state water officials indicate that reservoirs, rainfall totals and the
snowpack remain critically low. This follows two other dry or below average years,
leaving reservoir storage at alarmingly low levels. The January Proclamation highlights
the State's dry conditions, lack of precipitation and the resulting effects on drinking
water supplies, the cultivation of crops, and the survival of animals and plants that rely
on California's rivers and streams.
C. On April 1, 2015, Governor Brown issued Executive Order B-29-15 that,
among other things, directed the Department of Water Resources to update the State
Model Water Efficient Landscape Ordinance ("Model Ordinance") through expedited
regulation.
D. The purpose of the updated Model Ordinance is to increase water
efficiency standards for new and existing landscapes through more efficient irrigation
systems, greywater usage, onsite storm water capture, and by limiting the portion of
landscapes that can be covered in turf.

E. On July 15, 2015, the California Water Commission, acting on behalf of
the Department of Water Resources, approved the 2015 update to the Model
Ordinance.
F. The City Council is adopting the Model Ordinance in substantially the
same form as approved by the California Water Commission in order to promote the
efficient use of water within the City and to comply with the Governor's Executive Order
and Government Code Section 65595.
G. On October 21, 2015 the Planning Commission of the City of Temecula
held a duly noticed public hearing on this Ordinance providing an opportunity for the
public to comment on the Ordinance. After considering all written and oral comments
received, the Planning Commission adopted Resolution No. 15-22 recommending that
the City Council adopt this Ordinance.
H. On November 10, 2015 the City Council of the City of Temecula held a
duly noticed public hearing on this Ordinance providing an opportunity for the public to
comment on the Ordinance. The City Council considered all written and oral comments
received prior to its adoption of this Ordinance.
I. All legal prerequisites to the adoption of this Ordinance have been fulfilled.

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:
A. To 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. Conserving water by capturing and reusing rainwater and graywater wherever
possible and selecting climate appropriate plants that need minimal supplemental water
after establishment.
E. Protecting 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. Protecting existing habitat and creating new habitat by choosing local native
plants, climate adapted non-invasive and avoiding invasive plants. Utilizing integrated
pest management with least toxic methods as the first course of action.
G. To promote the values and benefits of landscape practices that integrate and go
beyond the conservation and efficient use of water.
H. To provide for provisions for water management practices and water waste
prevention.
To establish a structure for planning, designing, installing, maintaining, and
managing water efficient landscapes in new construction and rehabilitated projects by
Ords 15-11 3

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. To reduce landscape water demands without sacrificing landscape quality or
quantity.
K. To retain flexibility and encourage creativity through appropriate design.
L. To eliminate water waste from overspray and/or runoff.
M. To promote water conservation through public awareness.
N. To 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.

17.32.200. APPENDICES.
All references in this chapter to Appendix A, B, C and D are to the codified appendices
adopted by Ordinance No. 15-11."
Section 3. Adoption as an Urgency Ordinance. The City Council finds that
this ordinance is necessary for the immediate preservation of the public peace, health,
and safety, and declares that it shall take effect immediately upon its adoption as an
urgency ordinance pursuant to Government Code Sections 36934 and 36937. The
findings described in Sections 1 and 2 (§17.32.010) of this ordinance describe the
significant impacts on the drought facing the people of California and the people of the
City and the recognition by the Governor of these immediate impacts thought his
Emergency Proclamations concerning the drought and his Executive Orders expediting
the measures set forth in this Ordinance to reduce water consumption and reduce the
impacts of the drought.
Section 4. CEQA Findings. This project is exempt from the California
Environmental Quality Act (CEQA) pursuant to State CEQA Guidelines, 14 Cal. Code
Regs. Section 15307 and 15308, as an action taken to assure the maintenance,
restoration, or enhancement of a natural resource or the environment where the
regulatory process involves procedures for protection of the environment. This
Ordinance does not contemplate any construction activities and is limited to ensuring
water efficient landscaping options to preserve water. There is no evidence to suggest
that the Ordinance will result in a significant impact on the environment, including
impacts due to unusual circumstances. The adoption of this Ordinance includes
provisions that will result in the enhancement and protection of water resources in the
City. Based on the foregoing and other substantial evidence in the record, the City
Council hereby finds and determines that the Ordinance is exempt from the provisions
of CEQA, pursuant to State CEQA Guidelines Sections 15307 and 15308. As a
separate and independent ground, the City Council finds that the Ordinance is covered
by the general rule that CEQA applies only to projects that have the potential for
causing a significant effect on the environment. Because it can be seen with certainty
that there is no possibility that the Ordinance will have a significant effect on the
environment, the Ordinance is not subject to CEQA pursuant to State CEQA Guidelines
Section 15061 (b)(3).
Section 5. Severability. If any section, subsection, sentence, clause, or
phrase of this Ordinance is for any reason held to be invalid or unconstitutional by a
decision of any court of competent jurisdiction, such decision shall not affect the validity
of the remaining portions of this Ordinance. The City Council hereby declares that it
would have passed this Ordinance and each and every section, subsection, sentence,
clause or phrase not declared invalid or unconstitutional without regard to whether any
portion of the Ordinance would be subsequently declared invalid or unconstitutional.
