The proposed documents comply with AB1881, which states that the City's new ordinance must be "at least as effective as" the State's Model Ordinance, and requires that the ordinance be adopted by December 31, 2009, for implementation beginning January 1, 2010. RECOMMENDATION; Introduce the proposed Water Efficient Landscaping Ordinance and accompanying Design Standards, which will replace Chapter 14.17 of the Newport Beach Municipal Code, and pass to second reading on November 24, 2009. DISCUSSION: Background: History of State Legislation AB 325 (Water Conservation in Landscaping Act), passed by the State Legislature in 1992, required all cities and counties to adopt water efficient landscape ordinances which would establish procedures and standards of irrigation design and efficiency. The California Department of Water Resources (DWR) developed a Model Water Efficient Landscape Ordinance that established water efficient landscape design standards for urban landscapes which could serve as a template for local agencies to utilize in the development of their own local water efficient landscape ordinances. A local agency Planning Department November 10, 2009 Page 2 could adopt the DWR model ordinance outright, modify it to meet local needs, or adopt an entirely different ordinance. The act did not require agencies to adopt an ordinance that was "at least as effective as" the State Model. The City of Newport Beach adopted Chapter 14.17 of the Newport Beach Municipal Code in December, 1992 in response to AB325. AB1881 (Attachment: CC 3), passed in 2006, amended the Water Conservation in Landscaping Act (AB325). AB1881 required DWR to update the original State Model Water Efficient Landscape Ordinance and each city and county is required to update their local landscape ordinances by January 1, 2010 so that they are "at least as effective as" DWR's updated State Model Ordinance. If a city or county does not adopt a local ordinance, the updated State Model will take effect in that jurisdiction January 1, 2010. DWR is required to report back to the Legislature by 2011 on whether or not a local agency adopted a local ordinance. The focus of the State's Model Ordinance is to implement a more stringent regulatory process for larger landscape irrigation projects. Comparison of Landscape Irrigation Regulations Element 1992 (AB325) 2009 (AB 1881) Effectiveness No requirement Must be "at least as effective as" the State Model Evapotranspiration 1.0 0.7 Rate (30% reduction in water allocation for new landscapes) Applicable to: Non- residential projects, multi - family, public All areas, common areas (see exemptions stated below) Project Thresholds 1 acre of irrigated area 2500 sf for developer and public installed projects 5 000 sf when installed by a homeowner System Design Best Available Technology Must meet 07 ET Rate (Special Landscape areas -1.0) (Existing Landscapes -0.8) Projects Exempt from AB1881 (must comply with water conservation regulations) Registered historic sites Ecological restoration projects Public botanical gardens and arboretums Landscaping in Hazard Reduction and Fuel Modification Zones Landscape rehabilitation projects where replacement plantings have equal or lower water needs and irrigation system is designed, operable and programmed to comply with City's water conservation regulations Cemeteries (not required to submit a Landscape Design Package) 2 Planning Department November 10, 2009 Page 3 The Orange County Model Water Efficient Landscape Ordinance (OC Model) In response to the new landscape water efficiency requirements and public dialogue meetings, a stakeholder group was formed under the leadership of the Municipal Water District of Orange County (MWDOC) and the Orange County Division of the League of California Cities (the Division). The Division, in partnership with MWDOC, developed an OC Model for Orange County cities. Input into this process was broad and included city council members and city planning staff from various cities throughout Orange County, County planning staff, the Orange County Fire Authority and city fire department staff, water agency staff, Building Industry Association members, irrigation consultants, landscape architects, and other green industry representatives. The goal of the stakeholder group was to develop a locally- crafted model ordinance that would meet the "at least as effective as" requirement of State law, minimize the complexity and cost of compliance, and provide consistency among local jurisdictions. Stakeholder meetings and technical writing sessions took place from June 2009 through September 2009. While the State Model (Attachment: CC 4) contained 33 pages of policy issues and technical procedures, the approach taken by the Orange County group was to separate the policy issues and technical procedures into two documents; the OC Model Ordinance and Guidelines respectively. This resulted in an abbreviated and concise ordinance supported by a guidelines document which provides all process - oriented elements, equations, and technology - related components which will allow flexibility to incorporate future technical innovations in irrigation and water efficiency without having to amend the ordinance. The cornerstone of the OC Model Ordinance and Guidelines is a self - certification process that will streamline the permitting process and reduce costs for applicants and local agencies. The licensed professional designing the project is required to certify that the submitted landscape design is in conformance with the City Ordinance and Design Standards by signing (including their license number and /or professional stamp) a Certification of Landscape Design as part of the Landscape Documentation Package submittal. The Landscape Documentation Package must be submitted and approved prior to permit issuance. Once construction of the landscape is complete, the licensed professional completing the construction /installation is required to sign the Landscape Installation Certificate of Completion stating that the installation is complete and is in substantial conformance with the original plan. Once the Landscape Installation Certificate of Completion is accepted by the city, the permit can be finaled. Staff is recommending that Newport Beach adopt the OC Model Ordinance. 3 Planning Department November 10, 2009 Page 4 Potential Effects of AB 1881 Requirements to the City It is expected that the new State requirements and the proposed ordinance will have the potential to affect City public projects which require ministerial permits or discretionary review. However, projects which involve replanting with equal or lower water use plants where the irrigation system complies with the City's water conservation regulations are exempt from the requirements, which minimizes the number of projects affected. By way of example, most commercial projects more than likely would not meet the threshold of 2,500 square feet of landscaped area after maximizing the square footage allowed on the lot and providing the required parking and hardscape areas for pedestrian access. Developer installed landscape projects for residential areas could potentially be affected. Many common area projects meeting the threshold (2,500 square feet of landscaped area) would be rehabilitation projects because Newport Beach is almost fully developed and would be exempt if replanting with equal or lower water use plants and the irrigation system complies with the City's water conservation regulations. When considering homeowner installed landscaped areas on single and two -unit lots, staff estimates that approximately 15 percent of such lots meet the 5,000 square feet threshold and could be affected by the new requirements. When lots in Newport Coast, not yet under City permit jurisdiction, are factored in, the percentage of potential lots affected increases (17.6 percent). The analysis concludes that the percentage of residential lots affected by the new requirements is not significant. Conclusion The OC Model provided the framework for the proposed Water Efficient Landscape Ordinance and Design Standards (Attachments CC 1 and CC 2). While the State's Model Ordinance is a complex and lengthy document, the OC Model provides a framework which meets the "at least as effective as" the State's new Model Ordinance requirements. It provides as much simplicity, efficiency, and flexibility as possible. It allows a self - certification process which eliminates the need for additional layers of review and will minimize the cost of implementation. It provides consistency across the County for professionals trying to comply with the requirements, and will allow training opportunities for updates on a countywide basis. Staff, therefore, recommends adoption of the proposed new Water Efficiency Landscape Ordinance (Chapter 14.17 of the Municipal Code) which is based on the framework provided by the OC Model Ordinance. Environmental Review: This Ordinance has been determined to be categorically exempt from review under the requirements of the California Environmental Quality Act (CEQA) under Section 15307, Class 7 (Actions by Regulatory Agencies for Protection of Natural Resources). This I Planning Department November 10, 2009 Page 5 Class 7 (Actions by Regulatory Agencies for Protection of Natural Resources). This class provides an exemption for actions taken by regulatory agencies as authorized by state law or local ordinance which assure the maintenance, restoration, or enhancement of a natural resource where the regulatory process involves procedures for protection of the environment. The adoption of this Ordinance will result in the enhancement and protection of water resources in the City, and will not result in cumulative adverse environmental impacts. It is therefore exempt from the provisions of CEQA.

Notice of the time, place and purpose of the meeting was given in accordance with the Municipal Code; and NOW THEREFORE, THE CITY COUNCIL OF THE CITY OF NEWPORT BEACH, CALIFORNIA, HEREBY ORDAINS AS FOLLOWS: SECTION 1: Chapter 14.17 of Title 14 of the Newport Beach Municipal Code is hereby amended in its entirety to read as follows: CHAPTER 14.17: WATER EFFICIENT LANDSCAPING 14.17.005: Purpose 14.17.010: Definitions 14.17.020: Applicability 14.17.030: Landscape Water Use Standards 14.17.040: Implementation Procedures 14.17.005: Purpose The purpose of the City's Water Efficient Landscape Ordinance and Design Standards is to establish an alternative model acceptable under AB 1881 as being at least as effective as the State Model Water Efficient Landscape Ordinance, in order to: (1) promote the benefits of consistent landscape ordinances with neighboring local and regional agencies; (2) promote the values and benefits of landscapes while recognizing the need to invest water and other resources as efficiently as possible; (3) establish a structure for planning, designing, installing, and maintaining and managing water efficient landscapes in new construction and rehabilitated projects; 2 16 (4) establish provisions for water management practices and water waste prevention for existing landscapes; (5) use water efficiently without waste by setting a Maximum Applied Water Allowance as an upper limit for water use and reduce water use to the lowest practical amount; (6) encourage the use of economic incentives that promote the efficient use of water. 14.17.010: Definitions For the purposes of this chapter, the following words and phrases shall have the meaning set forth in this section. (a) Applied water: the portion of water supplied by the irrigation system to the landscape. (b) Budget -based tiered -rate structure: tiered or block rates for irrigation accounts charged by the retail water agency in which the block definition for each customer is derived from lot size or irrigated area and the evapotranspiration requirements of landscaping. (c) Design Standards: refers to the Design Standards for Implementation of the Water Efficient Landscape Ordinance, as adopted by the City, which describes procedures, calculations, and requirements for landscape projects subject to this Water Efficient Landscape Ordinance. (d) Ecological restoration project: a project where the site is intentionally altered to establish a defined, indigenous, historic ecosystem. (e) Estimated Applied Water Use (EAWU): the average annual total amount of water estimated to be necessary to keep plants in a healthy state, calculated as provided in the Design Standards. It is based on the reference evapotranspiration rate, the size of the landscape area, plant water use factors, and the relative irrigation efficiency of the irrigation system. (f) ET adjustment factor or "ETAF": is equal to the plant factor divided by the irrigation efficiency factor for a landscape project, as described in the Design Standards. The ETAF is calculated in the context of local reference evapotranspiration, using site - specific plant factors and irrigation efficiency factors that influence the amount of water that needs to be applied to the specific landscaped area. -- A combined plant mix with a site -wide average plant factor of 0.5 (indicating a moderate water need) and average irrigation efficiency of 0.71 produces an ET adjustment factor of (0.7) _ (0.5/0.71), which is the standard of water use efficiency generally required by this Water Efficient Landscape 3 Ordinance and the Design Standards, except that the ETAF for a special landscape area shall not exceed 1.0. (g) Hardscapes: any durable material or feature (pervious and non - pervious) installed in or around a landscaped area, such as pavements or walls. Surface area of pools and other water features are considered part of the landscaped area and not considered hardscapes for purposes of this Water Efficient Landscape Ordinance. (h) Homeowner installed landscape: any landscaping either installed by a private individual for a single family residence or installed by a licensed contractor hired by a homeowner. A homeowner, for purposes of this ordinance, is a person who occupies the dwelling he or she owns. This definition excludes speculative homes, which are not owner- occupied dwellings and which are subject under this ordinance to the requirements applicable to developer - installed residential landscape projects. (i) Irrigation efficiency: the measurement of the amount of water beneficially used divided by the amount of water applied. Irrigation efficiency is derived from measurements and estimates of irrigation system characteristics and management practices. The minimum average irrigation efficiency for purposes of this Water Efficient Landscape Ordinance is 0.71. Greater irrigation efficiency can be expected from well designed and maintained systems. An average plant factor of 0.5 (indicating a moderate water need) and average irrigation efficiency of 0.71 produces an ET adjustment factor of (0.7) _ (0.5/0.71) Q) Landscape Documentation Package: the documents required to be provided to the City for review and approval of landscape design projects, as described in the Design Standards. (k) Landscape rehabilitation project: any re- landscaping project that meets the criteria of Section 14.17.020 (Applicability), where the modified landscaped area is greater than 2,500 square feet (or 5,000 square feet for home owner installed) , is 50% of the total landscaped area, and the modifications are planned to occur within one year. (I) Landscaped area: all the planting areas, turf areas, and water features (including pools, ponds, fountains, and any other water feature) in a Landscape Design Plan which are subject to and must be included in the Maximum Applied Water Allowance and Estimated Applied Water Use calculations. The landscaped area does not include footprints of buildings or structures, sidewalks, driveways, parking lots, decks, patios, gravel or stone walks, other pervious or non - pervious hardscapes, and other non - irrigated areas designated for non - development (e.g., open spaces and existing native vegetation). (m) Licensed professional: a licensed landscape architect, California licensed landscape contractor, civil engineer, architect, or any other person authorized to design or construct a landscape pursuant to Sections 5500.1, 5615, 5641, 5641.1, 5641.2, M im 5641.3, 5641.4, 5641.5, 5641.6, 6701, 7027.5 of the California Business and Professions Code, Section 832.27 of Title16 of the California Code of Regulations, and Section 6721 of the California Food and Agriculture Code. (n) Local water supplier: any entity, including a public agency, city, county, or private water company that provides retail water service. (o) Maximum Applied Water Allowance (MAWA): is the upper limit of annual applied water for the established landscaped area as specified in Section 2.2 of the Design Standards. It is based upon the area's reference evapotranspiration, the ET Adjustment Factor, and the size of the landscaped area. The Estimated Applied Water Use shall not exceed the Maximum Applied Water Allowance. (p) Ministerial Permit: an authorizing document issued by the City of Newport Beach Building Department in conjunction with a landscape project which may include, but is not limited to: grading, pools, spas, fountains, ponds, retaining walls, fences and walls, shade structures, trellis structures, barbecues, outdoor fireplaces, etc. (q) New landscape installation project: a landscape installed in conjunction with any type of new development, whether or not the new development includes construction of new building(s). (Examples of a new development not associated with a new building could include parks, playgrounds, greenbelts). (r) Non - pervious: any surface or natural material that does not allow for the passage of water through the material and into the underlying soil. (s) Pervious: any surface or material that allows the passage of water through the material and into the underlying soil. (t) Plant factor or plant water use factor: is a factor, when multiplied by ETo, which estimates the amount of water needed by plants. For purposes of this Water Efficient Landscape Ordinance, the plant factor range for low water use plants is 0 to 0.3; the plant factor range for moderate water use plants is 0.4 to 0.6; and the plant factor range for high water use plants is 0.7 (70 %) to 1.0 (100 %). Plant factors cited in this Water Efficient Landscape Ordinance are derived from the Department of Water Resources 2000 publication "Water Use Classification of Landscape Species." (u) Recycled water or reclaimed water: a wastewater which, as a result of treatment, is suitable for non potable uses not intended for human consumption such as landscape irrigation and water features. (v) Reference evapotranspiration or "ETo ": a standard measurement of environmental parameters which affect the water use of plants. ETo is given expressed in inches per day, month, or year as represented in Appendix A of the Design Standards and is an estimate of the evapotranspiration of a large field of four -to seven -inch tall, cool- season 5 l� grass that is well watered. Reference evapotranspiration is used as the basis of determining the Maximum Applied Water Allowances (MAWA). (w) Smart automatic irrigation controller: an automatic timing device used to remotely control valves that operate an irrigation system and which schedules irrigation events using either evapotranspiration (weather- based) or soil moisture data. (x) Special Landscaped Area or SLA: an area of the landscape dedicated solely to edible plants such as orchards and vegetable gardens, areas irrigated with recycled water, water features using recycled water, and areas dedicated to active play such as parks, sports fields, golf courses, and where turf provides a playing These areas may have an ET adjustment factor (ETAF) to 1.0 (100 %). (y) Turf: a ground cover surface of mowed grass. Annual bluegrass, Kentucky bluegrass, Perennial ryegrass, Red fescue, and Tall fescue are cool- season grasses. Bermudagrass, Kikuyugrass, Seashore Paspalum, St. Augustinegrass, Zoysiagrass, and Buffalo grass are warm- season grasses. (z) Valve: a device used to control the flow of water in an irrigation system. (aa) Water feature: a design element where open water performs an aesthetic or recreational function. Water features include ponds, lakes, waterfalls, fountains, artificial streams, spas, and swimming pools (where water is artificially supplied). The surface area of water features is included in the high water use hydrozone of the landscaped area. Constructed wetlands used for on -site wastewater treatment, habitat protection or storm water best management practices that are not irrigated and used solely for water treatment or storm water retention are not water features and, therefore, are not subject to the water budget calculation. 14.17.020: Applicability. (a) Beginning January 1, 2010, all planting, irrigation, and landscape - related improvements required by this Water Efficient Landscape Ordinance shall apply to the following: (1) New landscape installation projects or landscape rehabilitation projects installed by public agencies or private non - residential developers, except for cemeteries, with a total project landscaped area (see definition) equal to or greater than 2,500 square feet and which require a ministerial permit for one or more landscape project components, and/or are subject to discretionary review and/or approval of a landscape plan.

Project applicant: the person submitting a Landscape Documentation Package required under Section 2.1 to request a permit, plan check, or design review from the City. A project applicant may be the property owner or his or her designee. Property owner or owner: the record owner of real property as shown on the most recently issued equalized assessment roll. Recycled water or reclaimed water: treated or recycled waste water of a quality suitable for non - potable uses such as landscape irrigation and water features. This water is not intended for human consumption. Reference evapotranspiration or ETo: a standard measurement of environmental parameters which affect the water use of plants. ETo is given expressed in inches per day, month, or year as represented in Appendix C of these Design Standards, and is an estimate of the evapotranspiration of a large field of four to seven -inch tall, cool- season grass that is well watered. Reference evapotranspiration is used as the basis of determining the Maximum Applied Water Allowances. Runoff: water which is not absorbed by the soil or landscape to which it is applied and flows from the landscaped area. For example, runoff may result from water that is applied at too great a rate (application rate exceeds infiltration rate) or when there is a slope. Special Landscaped Areas or SLA: an area of the landscape dedicated solely to edible plants such as orchards and vegetable gardens, areas irrigated with recycled water, water features using recycled water, and areas dedicated to active play such as parks, sports fields, golf courses, and where turf provides a playing surface. These areas may have an ET adjustment factor (ETAF) to 1.0 (100 %). E *a Aa Sprinkler head: a device which delivers water through a nozzle. Static water pressure: the pipeline or municipal water supply pressure when water is not flowing. Station: an area served by one valve or by a set of valves that operate simultaneously. Swing joint: an irrigation component that provides a flexible, leak -free connection between the emission device and lateral pipeline to allow movement in any direction and to prevent equipment damage. Turf: a ground cover surface of mowed grass. Annual bluegrass, Kentucky bluegrass, Perennial ryegrass, Red fescue, and Tall fescue are cool- season grasses. Bermudagrass, Kikuyugrass, Seashore Paspalum, St. Augustinegrass, Zoysiagrass, and Buffalo grass are warm - season grasses. Valve: a device used to control the flow of water in an irrigation system Water Efficient Landscape Ordinance: Ordinance No. adopted by the City Council on , 2009, and codified in the Municipal Code in Chapter 14.17. Water Efficient Landscape Worksheets: means the worksheets required to be completed pursuant to Section 2.2 of these Design Standards and which are included in Appendix C hereof. Water feature: a design element where open water performs an aesthetic or recreational function. Water features include ponds, lakes, waterfalls, fountains, artificial streams, spas, and swimming pools (where water is artificially supplied). The surface area of water features is included in the high water use hydrozone of the landscaped area. Constructed wetlands used for on -site wastewater treatment, habitat protection, or storm water best management practices that are not irrigated and used solely for water treatment or storm water retention are not water features and, therefore, are not subject to the water budget calculation. Watering window: the time of day irrigation is allowed.

(Approved by Governor September 29, 2006. Hcd with Sccrctmy of State September 28, 2006.] LFGISLXFIVE Cn UNSrVS DIGEST AB 1881, Laird. Water conservation. (1) Existing law, the Davis - Sterling Common Interest Development Act, defines and regulates common interest developments, which include community apartment projects, condominium projects, planned developments, and stock cooperatives. This bill would provide that the architectural guidelines of a common interest development shall not prohibit m include conditions that have the effete of prohibiting the use of taw water -using plants as a group. (2) The Water Conservation in Landscaping Act requires the Department of Water Resources to appoint an advisor y task force to work with the department to draft a model local water efficient landscape ordinance that local agencies may adopt, requires the task force to submit the ordinance to the department on or before May 1, 1991, and requires the task force to cease to exist on the date the department adopts the model ordinance or January 1, 1992, whichever occurs first. The act requires the department, not later than January 1, 1991 to adopt a model local water efficient landscape ordinance which each local agency may adopt. The act makes the model local water efficient landscape ordinance adopted by the department applicable within the jurisdiction of a local agency if that local agency, by January 1, 1993, . has not adopted a water efficient landscape ordinance or has not adopted certain findings that the adoption of the ordinance is unnecessary. This bill would specify that the provision making the model ordinance applicable to a local agency on and after January 1, 1993, does not apply to chartered cities. The bill would require the department, to the extent funds are appropriated, not later than January 1, 2009, by regulation, to update the model ordinance in accordance with specified requirements. The bill would require the department to prepare and submit to the Legislature a prescribed report before the adoption of the updated model ordinance. The bill would require a local agency, not later than January 1, 2010, to adopt the updated model ordinance or other water efficient 92 4N Ch. 559 —2— landscape ordinance that is at least as effective in conserving water as the updated model ordinance. The bill would make the updated model ordinance applicable within the jurisdiction of a local agency, including a chartered city, if, by January 1, 2010, the local agency has not adopted its own water efficient landscape ordinance or the updated model ordinance. The bill would require each local agency not later than January 31, 2010, to notify the department as to whether tine local agency is subject to the department's updated model ordinance and, if not, to submit to the department a copy of the water efficient landscape ordinance adopted by the local agency, among other documents. The bill would require the department, to the extent funds are appropriated, not later than January 31, 2011, to prepare and submit a report to the Legislature relating to the status of water efficient landscape ordinances adopted by local agencies. By imposing requirements on local agencies in connection with the adoption of water efficient landscape ordinances, the bill would impose a state - mandated local program. (3) Existing law requires the State Energy Resources Conservation and Development Commission (Energy Commission), after one or more public hearings, to take specified action to reduce the wasteful, uneconomic, inefficient, or unnecessary consumption of energy. Existing taw requires the Energy Commission, by January I, 2004, to amend specified regulations to require that residential clothes washers manufactured on or after January 1, 2007, be at least as water efficient as commercial clothes washers, and to take certain other related action. This bill would require the Energy Commission, in consultation with the department, to adopt, to the extent funds are available, by regulation performance standards and labeling requirements for landscape irrigation equipment, including irrigation controllers, moisture sensors, emission devices, and valves to reduce the wasteful, uneconomic, inefficient, or unnecessay consumption of energy or water. The bill would require the Energy Commission to adopt those requirements for landscape irrigation controllers and moisture sensors by January t, 2010, and, on and after January 1, 2012, would prohibit the sale or installation of an irrigation controller or moisture sensor for landscape use unless the controller or sensor meets those adopted requirements. The bill would require the Energy Commission, on or before January t, 2010, to prepare and submit to the Legislature a report that sets forth a proposed schedule for adopting performance standards and labeling requirements for emission devices and valves. (4) Existing law, generally requires an urban water supplier to install water meters on all municipal and industrial service connections located within its service area on or befog January 1, 2025. This bill would require a water purveyor as defined, to require as a condition of new retail water set-vice on and after January 1, 2008, the installation of separate water meters to measure the volume of water used exclusively for landscape purposes. The bill would make this requirement applicable to specified service corrections. 92 5 S" -3— C h. 559 (5) The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for snaking that reimbursement. This bill would provide that, if the Commission on State Mandates determines that the bill contains costs mandated by the state, reimbursement for those costs shall be made pursuant to these statutory provisions. The people ofthe State of California do enact as follows: SECTION 1. Section 1353.8 is added to the Civil Code, to read: 1353.8. The architectural guidelines of a common interest development shall not prohibit or include conditions that have the effect of prohibiting the use of low water -using plants as a group. SEC. 2. Article 10.8 (commencing with Section 65591) of Chapter-3 of Division i orTitle 7 of the Government Code is repealed. SEC. 3. Article 10.8 (commencing with Section 65591) is added to Chapter 3 of Division I of Title 7 of the Government Code, to read: Article 10.8. Water Conservation in Landscaping 65591.

(e) Landscape design, installation, maintenance, and management can and should be water efficient. (t) Section 2 of Article X of the California Constitution specifies that the right to use water is limited to the amount reasonably required for the 92 5� Ch. 559 —4— beneficial use to be served and the right does not and shall not extend to waste or unreasonable use or unreasonable method of use. (g) (1) The Legislature, pursuant to Chapter 632 of the Statutes of 2004, requested the California Urban Water Conservation Council to convene a stakeholders work group to develop recommendations for improving the efficiency of water use in urban irrigated landscapes. (2) The work group report includes a recommendation to update the model water efficient landscape ordinance adopted by the department pursuant to Chapter 1 145 of the Statutes of 1990. (3) it is the intent of the Legislature that the department promote the use of this updated model ordinance. (h) Notwithstanding Article 13 (commencing with Section 65700), this article addresses a matter that is of statewide concern and is not a municipal affair as that term is used in Section 5 of Article XI of the California Constitution. Accordingly, it is the intent of the Legislature that this article, except as provided in Section 65594, apply to all cities and counties, including charter cities and charter counties. 65594. (a) Except as provided in Section 65595, if by January 1, 1993, a local agency did not adopt a. water efficient landscape ordinance and did not adopt findings based on climatic, geological, or topographical conditions, or water availability that state that a water efficient landscape ordinance is unnecessary, the model water efficient landscape ordinance adopted by the department pursuant to Chapter 1145 of the Statutes of 1990 shall apply within the jurisdiction of the local agency as of that date, shall be enforced by the local agency, and shall have the same force and effect as if adopted by the local agency. (b) Notwithstanding subdivision (b) of Section 65592, subdivision (a) does not apply to chartered cities. (c) This section shall apply only until the department updates the model ordinance. 65595.

The ETo values used in these calculations are from the Reference Evapotranspiration Table in Appendix A, for planning purposes only. For actual irrigation scheduling, automatic irrigation controllers are required and shall use current reference evapotranspiration data, such as from the California Irrigation Management Information System (CIMIS), other equivalent data, or soil moisture sensor data. (1) Example MAWA calculation: a hypothetical landscape project in Fresno, CA with an irrigated landscape area of 50,000 square feet without any Special Landscape Area (SLA= 0, no edible plants, recreational areas, or use of recycled water). To calculate MAWA, the annual reference evapotranspiration value for Fresno is 51.1 inches as listed in the Reference Evapotranspiration Table in Appendix A. MAWA = (ETo) (0.62) [(0.7 x LA) + (0.3 x SLA)] MAWA = Maximum Applied Water Allowance (gallons per year) ETo = Reference Evapotranspiration (inches per year) 0.62 = Conversion Factor (to gallons) 0.7 = ET Adjustment Factor (ETAF) LA = Landscape Area including SLA (square feet) 0.3 = Additional Water Allowance for SLA SLA = Special Landscape Area (square feet) MAWA = (51.1 inches) (0.62) [(0.7 x 50,000 square feet) + (0.3 x 0)] = 1,108,870 gallons per year To convert front gallons per year to hundred - cubic -feet per year: = 1,1085870/748 = 1,482 hundred -cubic -feet per year (100 cubic feet = 748 gallons) (2) In this next hypothetical example, the landscape project in Fresno, CA has the same ETo value of 51.1 inches and a total landscape area of 50,000 square feet. Within the 50,000 square foot project, there is now a 2,000 square foot area planted with edible plants. This 2,000 square foot area is considered to be a Special Landscape Area. MAWA = (ETo) (0.62) [(0.7 x LA) + (0.3 x SLA)] MAWA = (51.1 inches) (0.62) [(0.7 x 50,000 square feet) + (0.3 x 2,000 square feet)] = 31.68 x [35,000 + 6001 gallons per year = 31.68 x 35,600 gallons per year = 1,127,808 gallons per year or 1,508 hundred -cubic -feet per year (d) Estimated Total Water Use. The Estimated Total Water Use shall be calculated using the equation below. The sum of the Estimated Total Water Use calculated for all hydrozones shall not exceed MAWA. ETWU= (E•To)(0.62) PFx `4 +SLA Where: ETWU = Estimated Total Water Use per year (gallons) ETo = Reference Evapotranspiration (inches) PF = Plant Factor from WUCOLS (see Section 491) HA = Hydrozone Area [high, medium, and low water use areas] (square feet) SLA = Special Landscape Area (square feet) 0.62 = Conversion Factor IE = Irrigation Efficiency (minimum 0.71) 0 �o (1) Example ETWU calculation: landscape area is 50,000 square feet; plant water use type, plant factor, and hydrozone area are shown in the table below. The ETo value is 51.1 inches per year. There are no Special Landscape Areas (recreational area, area permanently and solely dedicated to edible plants, and area irrigated with recycled water) in this example.

The ETWU (1,102,116 gallons per year) is less than MAWA (1,108,870 gallons per year). In this example, the water budget complies with the MAWA. (2) Example ETWU calculation: total landscape area is 50,000 square feet, 2,000 square feet of which is planted with edible plants. The edible plant area is considered a Special Landscape Area (SLA). The reference evapotranspiration value is 51.1 inches per year. The plant type, plant factor, and hydrozone area are shown in the table below.

For this example: MAWA = (51.1) (0.62) [(0.7 x 50,000) + (0.3 x 2,000)] = 31.68 x [35,000 + 600] = 31.68 x 35,600 = 1,127,808 gallons per year The ETWU (1,111,936 gallons per year) is less than MAWA (1,127,808 gallons per year). For this example, the water budget complies with the MAWA. Note: Authority Cited: Section 65595, Government Code. Reference: Section 65596, Government Code. §492.5 Soil Management Report.

(c) Design Standards: refers to the Design Standards for Implementation of the Water Efficient Landscape Ordinance, as adopted by the City, which describes procedures, calculations, and requirements for landscape projects subject to this Water Efficient Landscape Ordinance. (d) Ecological restoration project: a project where the site is intentionally altered to establish a defined, indigenous, historic ecosystem. (e) Estimated Applied Water Use (EAWU): the average annual total amount of water estimated to be necessary to keep plants in a healthy state, calculated as provided in the Design Standards. It is based on the reference evapotranspiration rate, the size of the landscape area, plant water use factors, and the relative irrigation efficiency of the Irrigation system. (f) ET adjustment factor or "ETAF": is equal to the plant factor divided by the irrigation efficiency factor for a landscape project, as described in the Design Standards. The ETAF is calculated in the context of local reference evapotranspiration, using site- specific plant factors and irrigation efficiency factors that influence the amount of water that needs to be applied to the specific landscaped area. — A combined plant mix with a site -wide average plant factor of 0.5 (indicating a moderate water need) and average irrigation efficiency of 0.71 produces an ET adjustment factor of (0.7) _ (0.510.71), which is the standard of water use efficiency generally required by this Water Efficient Landscape Ordinance and the Design Standards, except that the ETAF for a special landscape area shall not exceed 1.0. (g) Hardscapes: any durable material or feature (pervious and non- pervious) installed in or around a landscaped area, such as pavements or walls. Surface area of pools and other water features are considered part of the landscaped area and not considered hardscapes for purposes of this Water Efficient Landscape Ordinance. (h) Homeowner installed landscape: any landscaping either installed by a private individual for a single family residence or installed by a licensed contractor hired by a homeowner. A homeowner, for purposes of this ordinance, is a person who occupies the dwelling he or she owns. This definition excludes speculative homes, which are not owner-occupied dwellings and which are subject under this ordinance to the requirements applicable to developer- installed residential landscape projects. (i) Irrigation efficiency: the measurement of the amount of water beneficially used divided by the amount of water applied. Irrigation efficiency is derived from measurements and estimates of irrigation system characteristics and management practices. The minimum average imgation efficiency for purposes of this Water Efficient Landscape Ordinance is 0.71. Greater irrigation efficiency can be expected from well designed and maintained systems. An average plant factor of 0.5 (indicating a moderate water need) and average irrigation efficiency of 0.71 produces an ET adjustment factor of (0.7) _ (0.510.71) (j) Landscape Documentation Package: the documents required to be provided to the City for review and approval of landscape design projects, as described in the Design Standards. (k) Landscape rehabilitation project: any re- landscaping project that meets the criteria of Section 14.17.020 (Applicability), where the modified landscaped area is greater than 2,500 square feet (or 5,000 square feet for home owner installed) , is 50% of the total landscaped area, and the modifications are planned to occur within one year. (I) Landscaped area: all the planting areas, turf areas, and water features (including pools, ponds, fountains, and any other water feature) in a Landscape Design Plan which are subject to and must be included in the Maximum Applied Wafer Allowance and Estimated Applied Water Use calculations. The landscaped area does not include footprints of buildings or structures, sidewalks, driveways, parking lots, decks, patios, gravel or stone walks, other pervious or non pervious hardscapes, and other non - irrigated areas designated for non- development (e.g., open spaces and existing native vegetation).

(o) Maximum Applied Water Allowance (MAWA): is the upper limit of annual applied water for the established landscaped area as specified in Section 2.2 of the Design Standards. It is based upon the area's reference evapotranspiration, the ET Adjustment Factor, and the size of the landscaped area. The Estimated Applied Water Use shall not exceed the Maximum Applied Water Allowance. (p) Ministerial Permit: an authorizing document issued by the City of Newport Beach Building Department in conjunction with a landscape project which may include, but is not limited to: grading, pools, spas, fountains, ponds, retaining walls, fences and walls, shade strictures, trellis structures, barbecues, outdoor fireplaces, etc. (q) New landscape installation project: a landscape installed in conjunction with any type of new development, whether or not the new development includes construction of new building(s). (Examples of a new development not associated with a new building could include parks, playgrounds, greenbelts). (r) Non - pervious: any surface or natural material that does not allow for the passage of water through the material and into the underlying soil. (s) Pervious: any surface or material that allows the passage of water through the material and into the underlying soil. (t) Plant factor or plant water use factor: is a factor, when multiplied by ETo, which estimates the amount of water needed by plants. For purposes of this Water Efficient Landscape Ordinance, the plant factor range for low water use plants is 0 to 0.3; the plant factor range for moderate water use plants is 0.4 to 0.6; and the plant factor range for high water use plants is 0.7 (70 %) to 1.0 (100 %). Plant factors cited in this Water Efficient Landscape Ordinance are derived from the Department of Water Resources 2000 publication' Water Use Classification of Landscape Species." (u) Recycled water or reclaimed water: a wastewater which, as a result of treatment, is suitable for non potable uses not intended for human consumption such as landscape irrigation and water features. (v) Reference evapotranspiration or "ETo ": a standard measurement of environmental parameters which affect the water use of plants. ETo is given expressed in inches per day, month, or year as represented in Appendix A of the Design Standards and is an estimate of the evapotranspiration of a large freld of four -to seven -inch tail, cool- season grass that is well watered. Reference evapotranspiration is used as the basis of determining the Maximum Applied Water Allowances (MAWA). (w) Smart automatic Irrigation controller: an automatic timing device used to remotely control valves that operate an irrigation system and which schedules irrigation events using either evapotranspiration (weather - based) or soil moisture data. 5 (x) Special Landscaped Area or SLA: an area of the landscape dedicated solely to edible plants such as orchards and vegetable gardens, areas irrigated with recycled water, water features using recycled water, and areas dedicated to active play such as parks, sports fields, golf courses, and where turf provides a playing These areas may have an ET adjustment factor (ETAF) to 1.0 (100 %). (y) Turf: a ground cover surface of mowed grass. Annual bluegrass, Kentucky bluegrass, Perennial ryegrass, Red fescue, and Tail fescue are cool- season grasses. Bermudagrass, Kikuyugrass, Seashore Paspalum, St. Augustinegrass, Zoysiagrass, and Buffalo grass are warm- season grasses. (z) Valve: a device used to control the flow of water in an irrigation system. (aa) Water feature: a design element where open water performs an aesthetic or recreational function. Water features include ponds, lakes, waterfalls, fountains, artificial streams, spas, and swimming pools (where water is artificially supplied). The surface area of water features is included in the high water use hydrozone of the landscaped area. Constructed wetlands used for on-site wastewater treatment, habitat protection or storm water best management practices that are not irrigated and used solely for water treatment or storm water retention are not water features and, therefore, are not subject to the water budget calculation. 14.17.020: Applicability.
