Newport Beach Municipal Code ISSUE: Should the City Council adopt a new Water Efficient Landscaping Ordinance? RECOMMENDATION: Review, discuss and provide guidance to staff regarding the proposed Water Efficient Landscaping Ordinance and accompanying Design Standards document. 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 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. i N Planning Department January 12, 2010 Page 2 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. Following is a comparison of the requirements of AB325 and AB1881. In keeping with the requirements of AB1881, 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 2 500sf commercial,developer, HOA and public installed projects 5 000 sf homeowner installed System Design Best Available Technology Must meet 0.7 ET Rate (Special Landscape areas -1.0) (Existing Landscapes -0.8) Projects Exempt from AB1881 (all projects must comply with Chapter 14.16 of the Municipal Code (water conservation regulations) Landscape rehabilitation projects where replacement plantings have equal or lower water needs and the irrigation system is designed, operable and programmed to comply with City's water conservation regulations. Registered historical sites Public botanical gardens and arboretums Ecological restoration projects Landscaping in Hazard Reduction and Fuel Modification Zones Cemeteries are not required to submit a complete Landscape Design Package; but must comply with the following Sections: Water Efficient Landscape Calculations (2.2), and Post - Installation Irrigation Scheduling/Maintenance 2.8 and 2.9). 4 • 1z Planning Department January 12, 2010 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 fire department staff from various cities throughout the county, staff from various water agencies, 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) contains 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, and which allows'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 Guidelines 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. • Planning Department ' January 12, 2010 Page 4 Potential Effects of AB 1881 Requirements to the City The new State requirements and the proposed ordinance may 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; this minimizes the number of projects affected. Many commercial projects may 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 new landscape projects for residential areas could be affected. Because Newport Beach is almost fully developed, many common area projects meeting the threshold (2,500 square feet of landscaped area) would be rehabilitation projects 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 (some not yet under City permit jurisdiction) are factored in, the percentage of potential lots affected citywide increases (to. 17.6 percent of all city lots). • Summary The OC Model and Design Guidelines document (Attachment CC 5) provide the framework for the proposed Water Efficient Landscape Ordinance and Design Standards document (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 recommends adoption of the proposed new Water Efficiency Landscape Ordinance (Chapter 14.17 of the Municipal Code) and accompanying Design Standards document which is -based on the framework provided by the OC Model Ordinance and Design Guidelines document. 51 • Environmental Review: Planning Department January 12, 2010 Page 5 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.

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 related Design Standards document is to establish an alternative model acceptable under AB 1881 (2006) 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; . E /rl (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. 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 Desigh 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 11 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) 0) 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. (1) 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, 0 lJ� • 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' • E .II 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, or areas dedicated to active play such as parks, sports fields, golf courses, or areas where turf provides a playing surface. 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 stone 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.

Filed with Secretary or State September 28, 2006.1 LEGISLATIVE COUNSEL'S DICEST 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 or include conditions that have the effect of prohibiting the use of low water -using plants as a group. (2) The Water Conservation in Landscaping Act requires the Department of Water Resources to appoint an advisory 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, 1992, 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 • 4Ci 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 the 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 law requires the Energy Commission, by January 1, 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 • unnecessary 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 1, 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 1, 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 before January 1, 2025. - This bill would require a water purveyor as defined, to require as a condition of new retail water service 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 connections. 92 r11 u 1-1 -3— Ch. 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 making 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 of the State of California do enact os 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.

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)] = I;l08,870 gallons per year To convert from gallons per year to hundred - cubic -feet per year: = 1,108,870/748 = 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 = (ETo)(0.62) P x A + SLA IE 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 E El ka (1) Example ETWU calculation: landscape area is 50,000 square feet; plant water use type, plant factor, ^nd hydrozone area are shown in the table below. The ETo, value is 51.1 inches per year. There are no ecial 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. W Example ETWU, calculation: total landscape area is 50,000 square feet, 2,000 square feet of which is _anted with edible plants. The edible plant area is considered a Special Landscape Area (SLA).

The City may delegate to, or into a contract with, a local agency to implement, administer, and/or enforce any of the provisions of the Water Efficient Landscape Ordinance on behalf of the City. 5. Definitions. The following definitions are applicable to this [chapter /division/title]: "Applied water" means the portion of water supplied by the irrigation system to the landscape. "Budget -based tiered -rate structure" means 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., "Ecological restoration project" means a project where the site is intentionally altered to • establish a defined, indigenous, historic ecosystem. . "Estimated Applied Water Use" means the average annual total amount of water estimated to be necessary to keep plants in a healthy state, calculated as provided in the Guidelines. 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. "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 Guidelines. 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 Ordinance and the Guidelines, except that the ETAF for a special landscape area shall not exceed 1.0. "Guidelines" refers to the Guidelines 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. IN In t " Hardscapes" means any durable material or feature (pervious and non pervious) installed in or around a landscaped area, such as pavements or walls. Pools and other water features are considered part of the landscaped area and not considered hardscapes for purposes of this Water Efficient Landscape Ordinance. "Homeowner installed landscape" means 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. "Irrigation efficiency" means 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. "Landscaped area" means all the planting. areas, turf areas, and water features in a landscape design plan subject to 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). "Landscape contractor" means a person licensed by the State of California to construct, maintain, repair, install, or subcontract the development of landscape systems. "Landscape Documentation Package" means the documents required to be provided to the City for review and approval of landscape design projects, as described in the Guidelines. "Landscape project" means total area of landscape in a project, as provided in the definition of "landscaped area," meeting the requirements under Section 1.1 of this Water Efficient Landscape Ordinance. "Local agency" means a city or county, including a charter city or charter county, that is authorized by the City to implement, administer, and/or enforce any of the provisions of the Water Efficient Landscape Ordinance on behalf of the City. The local agency may be responsible for the enforcement or delegation of enforcement of this Water.Efficient Landscape Ordinance including, but not limited to, design review, plan check, issuance of permits, and inspection of a. landscape project. "Local water purveyor" means any entity, including a public agency, city, county, or private water company that provides retail water service. 7 .9 • • 10,1- • "Maximum Applied Water Allowance" or "MAWA" means the upper limit of annual applied water for the established landscaped area as specified in Section 2.2 of the Guidelines. 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. "Mined -land reclamation projects" means any surface mining operation with a reclamation plan approved in accordance with the Surface Mining and Reclamation Act of 1975. "New construction" means, for the purposes of this Water Efficient Landscape Ordinance, a new building with a landscape or other new landscape such as a park, playground, or greenbelt without an associated building. "Non pervious" means any surface or natural material that does not allow for the passage of water through the material and into the underlying soil. "Pervious" means any surface or material that allows the passage of water through the material and into the underlying soil. "Permit" means an authorizing document issued by local agencies for new construction or rehabilitated landscape. • "Plant factor" or `plant water use factor" is a factor, when multiplied by ETo, that 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 to 1.0. 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." "Recycled water" or "reclaimed water" means 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" means 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 Guidelines, 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. "Rehabilitated landscape" means any re- landscaping project that meets the applicability criteria of Section 1.1(a), where the modified landscape area is greater than 2,500 square feet, is 50% of the total landscape area, and the modifications are planned to occur within one year. • H 603 "Smart automatic irrigation controller" means 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. "Special landscape area" means 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. "Turf' means 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" means a device used to control the flow of water in an irrigation system. "Water feature" means 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. • [Note: Authority Cited: Section 65595, Government Code.

Purpose and Applicability 1.1 Purpose (a) The primary purpose of these Guidelines is to provide procedural and design guidance for project applicants proposing landscape installation or rehabilitation projects that are subject to the requirements of the Water Efficient Landscape Ordinance. This document is also intended for use and reference by City staff in reviewing and approving designs and verifying compliance with the Water Efficient Landscape Ordinance. The general purpose of the Water Efficient Landscape Ordinance is to promote the design, installation, and maintenance of landscaping in a manner that conserves regional water resources by ensuring that landscaping projects are not unduly water -needy and that irrigation systems are appropriately implemented to minimize water waste. (b) Other regulations affecting landscape design and maintenance practices are potentially applicable and should be consulted for additional requirements. These regulations include but may not be limited to: (LOCAL ACENCYMAY ADD OR DELETE FROM THIS LIS7; OR MAYADD THE SPECIFIC CODE SECTION NUMBERS, OR RELEVANT LAWS AND REGULATIONS (1) State of California Assembly Bill 1881; (2) National Pollutant Discharge Elimination Permit for the Municipal Separate Storm Sewer System; (3) Orange County Fire Authority Regulations for Fuel Modification in the Landscape; (4) Water Conservation and Drought Response Regulations of the Local Water Purveyor; (5) Regulations of the Local Water Purveyor governing use.of Recycled Water; (6) Zoning Code; (7) Building Code; (8) Specific Plans, Master Plans, General Plan, or similar land use and planning documents; and (9) Conditions of approval for a specific project 1.2 Applicability I 109 (a) The Water Efficient Landscape Ordinance and these Guidelines apply to all of the following landscape projects: (1) New landscape installations or landscape rehabilitation projects by public agencies or private non - residential developers with a landscaped area, including pools or other water features but excluding hardscape, equal to or greater than 2,500 square feet, and which are otherwise subject to a discretionary approval of a landscape plan or which otherwise require a ministerial permit for a landscape or water feature. (2) New landscape installations or landscape rehabilitation projects by developers or property managers of single- family and multi- family residential projects or complexes with a landscaped area, including pools or other water features but excluding hardscape, equal to or greater than 2,500 square feet, and which are otherwise subject to a discretionary approval of a landscape plan or which otherwise require a ministerial permit for a landscape or water feature (3) New landscape installation projects by individual homeowners on single - family or multi - family residential lots with a project landscaped area, including pools or other water features but excluding hardscape, equal to or greater than 5,000 square feet, and which are otherwise subject to a discretionary approval of a landscape plan or which otherwise require a ministerial permit for a landscape or water feature. • (b) A landscape rehabilitation project is subject to the requirements of the Ordinance and these Guidelines where (i) the modified landscaped area is greater than 2,500 square feet and represents at least 50% of the total landscaped area; and (ii) the modifications are planned to occur within one year. . The requirements of the Guidelines may be partially or wholly waived, at the discretion of the city or its designee,. for landscape rehabilitation projects that are limited to replacement plantings with equal or lower water needs and where the irrigation system . is found to be designed, operable and programmed consistent with minimizing water waste in accordance with local water purveyor regulations. (e) Unless otherwise determined by the City, the Water Efficient Landscape Ordinance and these Guidelines do not apply to: (1) registered local, state, or federal historical sites; (2) ecological restoration projects that do not require a permanent irrigation system; (3) mined -land reclamation projects that do not require a permanent irrigation system; or (4) plant collections; as part of botanical gardens and arboretums open to the public. //U 2. Submittal Requirements for New Landscape Installations or Landscape Rehabilitation Projects (a) Discretionary approval is typically required for landscape projects that are.subject to site plan reviews, or where a variance from a local building code is requested, or other procedural processes apply such that standard or special conditions of approval may be required by the City. Discretionary projects with conditions of approval may be approved administratively by city staff, or acted on formally by the Planning Commission, City Council, or other jurisdictional authority. A typical standard condition of approval reads: "Landscaping for the project shall be designed to comply with the City's Water Efficient Landscape Ordinance and with the Guidelines for Implementation of the Water Efficient Landscape Ordinance. " Landscape or water features that typically require a ministerial permit (i.e., a building, plumbing, electrical, or other similar permit), thereby triggering compliance with the Water Efficient Landscape Ordinance requirements independently of the need for discretionary approval include, but 'are not limited to, swimming pools, fountains.or ponds, retaining walls, and overhead trellises. 2,1 Elements of the Landscape Documentation Package (a) A Landscape Documentation Package is required to be submitted by the project applicant for review and approval prior to the issuance of ministerial permits for landscape or water features by the City, and prior to start of construction.

Reference: Section 65596, Government Code.] 4 • 2.2 Water Efficient Landscape Calculations and Alternatives (a) The project applicant shall provide the calculated Maximum Applied Water Allowance (MAWA) and Estimated Applied Water Use (EAWU) for the landscaped area as part of the Landscape Documentation Package submittal to the City. The MA WA and EAWU shall be calculated based on completing the Water Efficient Landscape Worksheets (in accordance with the sample worksheets in Appendix B). (b) The EAWU allowable for the landscaped area shall not exceed the MA WA. The MA WA shall be calculated using an evapotranspiration adjustment factor (ETAF) of 0.7 except for the portion of the MAWA applicable to any special landscaped areas within the landscape project, which shall be calculated using an ETAF of 1.0. Where the design of the landscaped area can otherwise be shown to be equivalently water - efficient, the project applicant may submit alternative or abbreviated information supporting the demonstration that the annual EAWU is less than the H WA, at the discretion of and for the review and approval of the local agency. (e) Water budget calculations shall adhere to the following requirements: • (1) The MA WA shall be calculated using the Water Efficient Landscape Worksheets and equation presented in Appendix B on page .B -1. The example calculation on page B -1 is a hypothetical example to demonstrate proper use of the equation. (2) The EAWU shall be calculated using the Water Efficient Landscape Worksheets and equation presented in Appendix B on page B -2. The example calculation on page B -2 is a hypothetical example. E (3) For the calculation of the MA WA and EAWU, a project applicant shall use the ETo values from the closest location listed the Reference Evapotranspiration Table in Appendix C. For geographic areas not covered in Appendix C, data from other cities located nearby in the same reference evapotranspiration zone may be used, as found in the CIMIS Reference Evapotranspiration Zones Map, Department of Water Resources, 1999. (4) For calculation of the EAWU, the plant water use factor shall be determined as appropriate to the project location from the Water Use Efficiency of Landscape Species (WUCOLS) Species Evaluation List. The plant factor is 0.1 for very low water use plants, 0.2 to 0.3 for low water use plants, 0.4 to 0.6 for moderate water use plants, and 0.7 to 1.0 for high water use plants. l,7 its (5) For calculating the EAWU, the plant water use factor shall be determined .• for each valve hydrozone based on the highest - water -use plant species within the zone. The plant. factor for each hydrozone may be required to be further refined as a "landscape coefficient," according to protocols defined in detail in the WUCOLS document, to reflect planting density and microclimate effects on water need at the option of the project applicant or the City. (6) For calculation of the EAWU, the area of a water feature shall be defined as a high water use hydrozone with a plantfactor of 1.0. (7) For calculation of the EAWU, a temporarily irrigated hydrozone area, such as an area of highly drought- tolerant native plants that are not intended to be irrigated after they are fully established, shall be defined as a very low water use hydrozone with a plant factor of 0.1. (8) For calculation of the MA WA, the ETAF for special landscaped areas shall be set at 1.0. For calculation of the EAWU, the ETAF for special landscaped areas shall be calculated as the special landscaped area (SLA) . plant factor divided by the SLA irrigation efficiency factor. (9) Irrigation efficiency shall. be calculated using the worksheet and equation presented in Appendix B on page B -2. (d) The Maximum Applied Water Allowance shall adhere to the following •. requirements.: (1) The Maximum Applied Water Allowance shall be calculated using the equation presented in Appendix B. The example calculation in Appendix B is hypothetical' to demonstrate proper use of the equation and does not represent an existing and /or planned landscape project. The reference evapotranspiration (ETo) values used in this calculation are from the Reference Evapotranspiration Table in Appendix C and are for planning purposes only. For actual irrigation scheduling, automatic irrigation controllers are required and shall use current ETo data, such as from the California Irrigation Management Information System (CIMIS), other equivalent data, or soil moisture.sensor data. 2.3 Soil Management Report (a) In order to reduce runoff and encourage healthy plant growth, a soil management report shall be completed by the project applicant, or his/her designee, as follows: (1) Submit soil samples to a certified agronomic soils laboratory for analysis and recommendations. 3 • (a) Soil sampling shall be conducted in accordance with laboratory protocol, including protocols regarding adequate sampling depth for the intended plants.

"Lateral line" means the water delivery pipeline that supplies water to the emitters or sprinklers from the valve. "Low volume irrigation" means the application of irrigation water at low pressure through a system of tubing or lateral lines and low - volume emitters such as drip, drip lines, and bubblers. Low volume irrigation systems are specifically designed to apply small volumes of water, slowly at or near the root zone of plants. "Main line" means the pressurized pipeline that delivers water from the water source to the valve or outlet. "Maximum Applied Water Allowance" or "MAFIA" means the upper limit of annual applied water for the established landscaped area, as specified in Section 2.2 of these Guidelines.
