Zoning Ordinance Amendment No. 2009-07 <br /> November 9, 2009 <br /> Page 2 <br /> January 1, 2010 to be "at least as effective as" DWR's updated Model <br /> Ordinance. These new State requirements will necessitate amendments to <br /> the City's zoning ordinance. In response to the new water efficiency <br /> requirements, a stakeholder group was formed under the leadership of the <br /> Municipal Water District of Orange County (MWDOC) and the Orange County <br /> Division of the League of California Cities (the Division). The i <br /> stakeholder group included representatives from the county, cities, <br /> local water agencies, Building Industries Association (BIA), Orange <br /> County Fire Authority, irrigation consultants, landscape architects, and <br /> other green industry professionals. The goal of the group was to <br /> develop an Orange County Model Water Efficient Landscape Ordinance (OC <br /> <br /> Model) that, among other things, would meet the "at least as effective <br /> as" requirement. The new requirements include the following changes: <br /> 1. Reduces the irrigated area compliance threshold from one acre to <br /> 2,500 square feet for developer-installed projects, public agency <br /> projects, and private development projects requiring a building or <br /> landscape permit, plan check, or design review. <br /> 2. Now requires homeowner-provided or homeowner-hired projects <br /> exceeding 5,000 square feet of irrigated area to acquire a building <br /> or landscape permit, plan check, or design review. <br /> 3. Local ordinances must now be "at least as effective as" the State <br /> Model and documented "on the record." <br /> 4. Jurisdictions must now utilize evapo-transpiration based "Maximum <br /> Applied Water Allowance" (MAWA) rates of 0.7 instead of 1.0. The <br /> use of the new MAWA rate represents a 30o reduction in water <br /> allocation for new landscapes. <br /> 5. Water purveyors are now required to offer landscape surveys and/or <br /> incentive programs targeting landscape irrigation efficiency for <br /> new and existing landscapes. <br /> 6. Local ordinances must now address smaller landscaping projects <br /> including single-family residential projects. <br /> 7. Local jurisdictions must now regulate existing landscapes for water <br /> waste. <br /> 7 5A-4 <br /> <br />
