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. All legal prerequisites to the adoption of this Ordinance have been fulfilled. Section 2.

All references in this chapter to Appendix A, B, C and D are to the codified appendices adopted by Ordinance No. 15- II 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. Section 6. Notice of Adoption. The City Clerk shall certify to the passage and adoption of this Ordinance and shall cause the same to be published or posted in the manner required by law.
