Adoption a resolution approving the Santa Ana Water Efficient Landscape Guidelines 2015. Reguest of Applicant The City of Santa Ana is requesting to update the existing Water Efficient Landscape Ordinance and to be in compliance with the recently adopted State Water Efficiency Model Ordinance, Project Description The proposed amendment to Chapter 41 (Zoning Code) of the Santa Ana Municipal Code (SAMC) will update the requirements and definitions for landscaping and irrigation to further promote water conservation. This amendment to the Zoning Code is based on the Orange County Municipal Water District of Orange County (MWDOC) "regional" model ordinance to facilitate consistency in implementation among local Orange County communities. New development projects that include landscape areas of 500 square feet or more are subject to the ordinance. This applies to residential, commercial, industrial and institutional projects that require a building or landscape permit, plan check, or design /development review. Prolect Background In 1992, the State of California enacted the Water Conservation in Landscaping Act, requiring the adoption of a water efficient landscape ordinance by cities and counties throughout the state. In 2006, AB 1881 required updates to local water conservation ordinances by January 1, 2010. In accordance with state law, the City of Santa Ana updated its ordinance, which was codified in Chapter 41 (Sections 1500 through 1504). EXHIBIT A 75C -3 Zoning Ordinance Amendment 2015 -04 December 14, 2015 Page 2 With the drought conditions at emergency levels, in April 2015 Governor Brown signed an Executive Order (EO B- 29 -15) to further water conservation ordinance. Two key components of the Executive Order included: 1) The Department of Water Resources (DWR) to update the original Model Water Efficient Landscape Ordinance (MWELO) of 2009; and 2) cities and counties to update their local Landscape Ordinances, so they are "at least as effective as" DWR's updated Model Ordinance. In response to this mandate, a stakeholder group was formed under the leadership of the Municipal Water District ( MWDOC) of Orange County earlier this year. The Orange County Model Ordinance and Guidelines were completed in October 2015 and has been reviewed by City staff as well as the City Attorney, The guiding principles of the County Model are local control, consistency among Orange County cities, and promoting the values and benefits of landscapes while recognizing the need for efficient use of water. The County MWELO upholds the "at least as effective" threshold in relation to the State MWELO. The proposed zoning code amendment incorporates the criteria and guidelines of the 'regional" MWDOC model ordinance as highlighted below: • New residential, commercial, industrial and public development projects that include landscape areas of 500 square feet or more would be subject to the ordinance. The previous landscape size threshold for new development projects was 2,500 square feet, • The size threshold for existing landscapes that are being rehabilitated remains at 2,500 square feet. • The ordinance applies to landscape projects that require a permit, plan check or development review. • Dedicated landscape water meters or submeters are required for residential landscapes over 5,000 square feet and nonresidential landscapes over 1,000 square feet. • High efficiency irrigation systems must meet the national standard contained in the state ordinance. • Landscape areas, including public medians, less than 10 feet wide must be irrigated with drip irrigation. • A Prescriptive Compliance Option is added as incentive for graywater usage and for landscapes less than 2,500 square feet. This option provides for a simplified landscape plan submittal. • Best management practices to improve soil and maximize water retention and infiltration onsite. • The maximum amount of water that can be applied on a landscape is reduced, which would effectively reduce the amount of turf to approximately 25 percent of the residential landscape areas for a commercial lot, turf would not be feasible. Special function areas, such as active recreational landscapes and edible gardens, are to be given an increased water allowance. 75C -4 Zoning Ordinance Amendment 2015 -04 December 14, 2015 Page 3 • A public education component requires new model homes to provide water efficient landscapes and signage demonstrating low water use approaches to landscaping. The Water Efficient Ordinance Update is detailed in Exhibit 1, with the procedural details implementing this Ordinance explained in Exhibit 2, entitled Santa Ana Water Efficient Landscape Guidelines 2015, Proposed Zoning Ordinance Amendment 2015 -04 also directs synthetic turf guidelines to be in keeping with recent legislation. As directed by State law, the use of synthetic turf as an option for required landscape area may not be limited or restricted by local ordinance. Thus, the Synthetic Turf Design Standard will be updated administratively to comply with State law, and assure a best practices and sustainability of the synthetic products. The proposed modifications to the City' Municipal Cade and adoption of the updated Water Efficient Landscape Ordinance will bring the City's laws into compliance with the State water conservation mandate. Further, these requirements and guidelines will enhance the water conservation efforts currently being implemented throughout the City. As a result, staff recommends that the Planning Commission recommend the City Council adopt Zoning Ordinance Amendment No 2015 -04. Stakeholder Outreach The stakeholder group assisting in the development of the "regional" water efficiency model ordinance included representatives from the county, cities, local water agencies, Building Industries Association (BIA), Association of California Cities - Orange County (ACC -OC), irrigation consultants, landscape architects, and other industry professionals. Staff from the Planning Division and Public Works Agency participated in this effort. The goal of the stakeholder group was to develop a locally - crafted update to Orange County's Model Water Efficient Landscape Ordinance. The group was charged with meeting the "at least as effective as" the State Model Ordinance requirement, minimizing the complexity, streamlining compliance, and providing consistency between local jurisdictions. Public notification included a mailing to interested parties. In addition, a notice was published in the Orange County Register advertising the Planning Commission public hearing. CEQA Analysis In accordance with the California Environmental Quality Act, the proposed project is exempt from further review pursuant to Section 15307. This Class 7 exemption, Actions by Regulatory Agencies for Protection of Natural Resources, is applicable because the project implements State law to protect water resources. Categorical Exemption Environmental Review No. 2015 -114 will be filed for this project. 75C -5 Zoning Ordinance Amendment 2015 -04 December 14, 2015 Page 4 Strategic Plan Alignment Approval of this item supports the City's efforts to meet Goal No. 5 Community Health, Livability, Engagement and Sustainability, Objective No. 2 (expand opportunities for conservation and environmental sustainability). Conclusion Based on the analysis provided within this report, staff recommends that the Planning Commission recommend that the City Council adopt an ordinance approving Zoning Ordinance Amendment No. 2015 -04.

NS -XXX AN ORDINANCE OF THE CITY COUNCIL OF THE CITY OF SANTA ANA AMENDING CHAPTER 41 OF THE SANTA ANA MUNICIPAL CODE TO UPDATE THE WATER EFFICIENT LANDSCAPE ORDINANCE THE CITY COUNCIL OF THE CITY OF SANTA ANA DOES ORDAIN AS FOLLOWS: SECTION 1. The City Council of the City of Santa Ana hereby finds, determines, and declares as follows: A. In 1992, the State of California enacted the Water Conservation in Landscaping Act requiring the adoption of a water efficient landscape ordinance by cities and counties throughout the state. AB 1881, signed in 2006, required updates to local ordinances by January 1, 2010. In accordance with state law, the City of Santa Ana updated its ordinance, which was codified in Santa Ana Municipal Code in Chapter 41 Sections 1500 through 1504. B. With the drought conditions at emergency levels, in April 2015 Governor Brown signed an Executive Order (ED B- 29 -15) directing local agencies to update their ordinance to further water conservation and continue with efforts to substantially reduce water usage for residential, commercial and industrial landscape areas. C. Two key components of the Executive Order require: 1) The Department of Water Resources (DWR) to update the original Model Water Efficient Landscape Ordinance (MWELO) of 2009; and 2) cities and counties to update their local Landscape Ordinances, so they are "at least as effective as" DWR's updated Model Ordinance. D. In response to this mandate, a stakeholder group was formed under the leadership of the Municipal Water District (MWDOC) of Orange County earlier this year. The Orange County Model Ordinance and Guidelines were complete in October 2015 and have been reviewed by City staff as well as the City Attorney. The guiding principles of the County Model are local control, consistency among Orange County cities, and promoting the values and benefits of landscapes while recognizing the need for efficient use of water. The proposed zoning code amendment incorporates the criteria and guidelines of the "regional" Orange County Model Ordinance and Guidelines, and upholds the "at least as effective' threshold in relation to the State MWELO. E. The ordinance applies to landscape projects that require a permit, plan check or development review. New residential, commercial, industrial and public 75C -7 development projects that include landscape areas of 500 square feet or more would be subject to the ordinance. The previous landscape size threshold for new development projects was 2,500 square feet. The size threshold for existing landscapes that are being rehabilitated remains at 2,500 square feet. F. This Ordinance Amendment also addresses the allowance of synthetic turf requirements to be in compliance with recent legislation. As directed by State law, the use of synthetic turf as an option for required landscape area may not be unreasonably limited or restricted by local ordinance. The City's Synthetic Turf Design Standard will be updated to comply with State law and assure quality and sustainability of the synthetic products. G. The proposed modifications to the City Municipal Code and adoption of the updated Water Efficient Landscape Ordinance will bring the City's laws into compliance with the State water conservation mandate and other Orange County communities. Further, these requirements and guidelines will enhance the water conservation efforts currently being implemented throughout the City. SECTION 2.

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 designed and installed 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: (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 75C -27 January 11, 2016 1.2 Applicability (A) The Water Efficient Landscape Ordinance and these Guidelines apply to all of the following landscape projects: (1) New landscape projects with an aggregate landscape area equal to or greater than 500 square feet, requiring a building or landscape permit, plan check or development review; (2) Rehabilitated landscape projects with an aggregate landscape area equal to or greater than 2,500 square feet, requiring a building or landscape permit, plan check or development review; (3) New or rehabilitated landscape projects with an aggregate landscape area of 2,500 square feet or less may comply with the performance requirements of this ordinance or conform to the prescriptive measures contained in Appendix A; (4) New or rehabilitated projects using treated or untreated graywater or rainwater capture on site, any lot or parcels within the project that has less than 2,500 square feet of landscape area and meets the lot or parcel's landscape water requirement (Estimated Total Water Use) entirely with the treated or untreated graywater or though stored rainwater capture on site is subject only to Appendix A Section (5). (B) 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. (C) 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. 75C -28 January 11, 2016 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: "Landwaping 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 (B) 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. Unless otherwise directed by the City, the Landscape Documentation Package shall include the following elements either on plan sheets or supplemental pages as directed by the City: (1) Project Information, including, but not limited to, the following: (a) Date; (b) Project name; (e) Project address, parcel, and/or lot number(s); (d) Total landscape area (square feet) and rehabilitated landscape area (if applicable); (e) Project type (e.g., new, rehabilitated, public, private, cemetery, homeowner - installed); (f) Water supply type (e.g., potable, recycled, or well) and identification of the local retail water purveyor if the project applicant is not served by a private well; 75C -29 January 11, 2016 (g) Checklist or index of all documents in the Landscape Documentation Package; (h) Project contacts, including contact information for the project applicant and property owner; (i) Certification of Design in accordance with Exhibit B of these Guidelines that includes a landscape professional's professional stamp, as applicable, signature, contact information (including email and telephone number), license number, and date, certifying the statement that "The design of this project complies with the requirements of the City's Water If Landscape Ordinance" and shall bear the signature of the landscape professional as required by law; and (j) Any other information the City deems relevant for determining whether the landscape project complies with the Water Efficient Landscape Ordinance and these Guidelines. (2) Maximum Applied Water Allowance (MAWA) and Estimated Applied Water Use (EAWU) expressed as annual totals including, but not limited to, the following: (a) Water Efficient Landscape Worksheet (optional at discretion of the City) for the landscape project; (b) Hydrozone information table (optional at the discretion of the City) for the landscape project; and (c) Water budget calculations (optional at the discretion of the City) for the landscape project. (3) A soil management report or specifications, or specification provision requiring soil testing and amendment recommendations and implementation to be accomplished during construction of the landscape proj ect. (4) A landscape design plan for the landscape project. (5) An irrigation design plan for the landscape project. (6) A grading design plan, unless grading information is included in the landscape design plan for the landscape project or unless the landscape project is limited to replacement planting and/or irrigation to rehabilitate an existing landscape area. [Note: Authority Cited: Section 65595, Government Code. Reference: Section 65596, Government Code.] El 75C -30 January 11, 2016 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 landscape area as part of the Landscape Documentation Package submittal to the City. The MAWA and EAWU shall be calculated based on completing the Water Efficient Landscape Worksheets (in accordance with the sample worksheets in Appendix C) which contain information on the plant factor, irrigation method, irrigation efficiency and area associated with each hydrozone. Calculations are then made to show that the evapotranspiration adjustment factor (ETAF) for the landscape project does not exceed a factor of 0.55 for residential areas and 0.45 for non - residential areas, exclusive of Special Landscape Areas. The ETAF for a landscape project is based on the plant factors and irrigation methods selected. The Maximum Applied Water Allowance is calculated based on the maximum ETAF allowed (0.55 for residential areas and 0.45 for non - residential areas) and expressed as annual gallons required. The EAWU is calculated based on the plants used and irrigation method selected for the landscape design. (B) The EAWU allowable for the landscape area shall not exceed the MAWA. The MAWA shall be calculated using an evapotranspiration adjustment factor (ETAF) of 0.55 for residential areas and 0.45 for non - residential areas, except for the portion of the MAWA applicable to any Special Landscape Areas within the landscape project, which shall be calculated using an ETAF of 1.0. Where the design of the landscape 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 MAWA, at the discretion of and for the review and approval of the local agency. (C) Water budget calculations shall adhere to the following requirements: (1) The MAWA shall be calculated using the Water Efficient Landscape Worksheets and equation presented in Appendix C on page 25. The example calculation is a hypothetical example to demonstrate proper use of the equation. (2) The EAWU shall be calculated using the Water Efficient Landscape Worksheet and equations presented in page 26 of Appendix C. (3) For the calculation of the MAWA and EAWU, a project applicant shall use the ETo values from the closest location listed the Reference Evapotranspiration Table in Appendix D. For geographic areas not covered in Appendix D, data from other cities, or zip codes, located nearby in the same reference evapotranspiration zone may be used. (4) For calculation of the EAWU, the plant water use factor shall be detern7ined as appropriate to the project location from the Water Use 75C -31 January 11, 2016 Efficiency of Landscape Species (WUCOLS) Species Evaluation List or from horticultural researchers with academic institutions or professional associations as approved by the California Department of water Resources (DWR). The plant factor ranges from 0 to 0.1 for very low water use plants, 0.1 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. (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 EA UV, the area of a water feature shall be defined as a high water use hydrozone with a plant factor 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 MAWA, the ETAF for Special Landscape Areas (SLA) shall be set at 1.0. For calculation of the EAWU, the ETAF for SLA shall be calculated as the SLA plant factor divided by the SLA irrigation efficiency factor. (9) Irrigation efficiency (IE) of the irrigation heads used within each hydrozone shall be assumed to be as follows, unless otherwise indicated by the irrigation equipment manufacturer's specifications or demonstrated by the project applicant: Irrigation Method DULQ DULH* EU IE ** Spray nozzles 65% 79% 71% High efficiency spray nozzles 70% 82% 73% Multi stream/Multi trajectory rota MSMT) nozzles 75% 85% 76% Stream rotor nozzle 70% 82% 73% Microspray 75% 85% 76% Bubblers 1 1 85% 1 77% Drip emitter 90% 81% Subsurface drip 90% 81% *DULH =.386 + (.614)(DULQ ** IE (spray) _ (DULH)(IME) ** IE (drip) = Emission uniformity (EU)(IME) 6 75C -32 January 11, 2016 (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 C. The reference evapotranspiration (ETo) values used for this calculation are from the Reference Evapotranspiration Table in Appendix D 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 and Stormwater Management (A) All planted landscape areas are required to have friable soil to maximize retention and infiltration. On engineered slopes, only amended planting holes need meet this requirement. (B) 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. (a) Soil sampling shall be conducted in accordance with laboratory protocol, including protocols regarding adequate sampling depth for the intended plants. (b) The soil analysis may include, but is not limited to: 1. soil texture; 2. infiltration rate determined by laboratory test or soil texture infiltration rate table; 3. pH; 4. total soluble salts; 5. sodium; 6. percent organic matter; and 7. recommendations. (2) In projects with multiple landscape installations (i.e. production home developments or common interest developments that are installing landscaping) a soil sampling rate of 1 in 7 lots or approximately 15% will 7 75C -33 January 11, 2016 satisfy this requirement; evenly disbursed throughout the development. Large landscape projects shall sample at a rate equivalent to 1 in 7 lots or approximately 15% landscape area. The project applicant, or his /her designee, shall comply with one of the following: (a) If significant mass grading is not planned, the soil analysis report shall be submitted to the local agency as part of the Landscape Documentation Package; or (b) If significant mass grading is planned, the soil analysis report shall be submitted to the City as part of the Certification of Completion. (c) The soil analysis report shall be made available, in a timely manner, to the professionals preparing the landscape design plans and irrigation design plans in order to make any necessary adjustments to the design plans. (d) The project applicant, or his /her designee, shall submit documentation verifying implementation of soil analysis report recommendations to the local agency with the Certification of Completion. [Note: Authority Cited: Section 65595, Government Code. Reference: Section 65596, Government Code.] (C) It is strongly recommended that landscape areas be designed for capture and infiltration capacity that is sufficient to prevent runoff from impervious surfaces (i.e. roof and paved areas) from additional capacity as required by any applicable local, regional, state, or federal regulation and/or one of the following: the one inch, 24 -hour rain event or the 85b percentile, 24 -hour rain event. (D) It is recommended that storm water projects incorporate any of the following elements to improve on -site stormwater and dry weather runoff capture and use: (1) Grade impervious surfaces, such as driveways, during construction to drain into vegetated areas. (2) Minimize the area of impervious surfaces such as paved areas, roof, and concrete driveways. (3) Incorporate pervious or porous surfaces (e.g. gravel, permeable pavers or blocks, pervious or porous concrete) that minimize runoff. (4) Direct runoff from paved surfaces and roof areas into planting beds or landscape areas to maximize site water capture and reuse. (5) Incorporate rain gardens, cisterns, and other rain harvesting or catchment systems. 75C -34 January 11, 2016 (6) Incorporate infiltration beds, swales, basins, and drywells to capture stonnwater and dry weather runoff and increase percolation into the soil. (7) Consider constructed wetlands and ponds that retain water, equalize excess flow, and filter pollutants. [Note: Authority cited: Section 65595, Government Code. Reference: Section 65596, Government Code.] 2.4 Landscape Design Plan (A) For the efficient use of water, a landscape shall be carefully designed and planned for the intended function of the project.

Allowable irrigation within the setback from non - permeable surfaces may include drip, drip line, or other low flow non -spray technology. The setback area may be planted or unplanted. The surfacing of the setback may be mulch, gravel, or other porous material. These restrictions may be modified if: 1. the landscape area is adjacent to permeable surfacing and no runoff occurs; or 2. the adjacent non - permeable surfaces are designed and constricted to drain entirely to landscaping; or 3. the irrigation designer for the landscape project specifies an alternative design or technology, as part of the Landscape Documentation Package, and clearly demonstrates strict adherence to the irrigation system design criteria in Section 2.5 (a)(1)(H) hereof. Prevention of overspray and runoff must be confirmed during an irrigation audit. 4. slopes greater than 25% shall not be irrigated with an irrigation system with a application rate exceeding 0.75 inches per hour. This restriction may be modified if the landscape designer of 15 75C -41 January 11, 2016 the landscape project specifies an alternative design or technology, as part of the Landscape Documentation Package, and clearly demonstrates no runoff or erosion will occur. Prevention of runoff and erosion must be confirmed during the irrigation audit. (2) Hydrozone (a) Each valve shall irrigate a hydrozone with similar site, slope, sun exposure, soil conditions, and plant materials with similar water use. (b) Sprinkler heads and other emission devices shall be selected based on what is appropriate for the plant type within that hydrozone.

"Backflow prevention device" means a safety device used to prevent pollution or contamination of the water supply due to the reverse flow of water from the irrigation system. "Check valve" or "anti -drain valve" means a valve located under a sprinkler head, or other location in the irrigation system, to hold water in the system to prevent drainage from sprinkler heads when the sprinkler is off. "Certified Landscape Irrigation Auditor" means a person certified to perform landscape irrigation audits by an accredited academic institution, a professional trade organization or other program such as the US Environmental Protection Agency's WaterSense irrigation auditor certification program and Irrigation Association's Certified Landscape Irrigation Auditor program. "Certification of Design" means the certification included as Exhibit E of these Guidelines that must be included in the Landscape Documentation Package pursuant to Section 2.1 of these Guidelines. "City" means the City of Santa Ana or its authorized designee "Common interest developments" means community apartment projects, condominium projects, planned developments, and stock cooperatives per Civil Code Section 1351 "Distribution Uniformity" or "DU' is a measure of how uniformly an irrigation head applies water to a specific target area and theoretically ranges from zero to 100 percent. "Drip" irrigation means any non -spray low volume irrigation system utilizing emission devices with a flow rate measured in gallons per hour. Low volume irrigation systems are specifically designed to apply small volumes of water slowly at or near the root zone of plants. "Emitter" means a drip irrigation emission device that delivers water slowly from the system to the soil. "Estimated Applied Water Use" or "EAWU" means the annual total amount of water estimated to keep plants in a healthy state. It is based on factors such as reference evapotranspiration rate, the size of the landscape area, plant water use factors, and the irrigation efficiency within each hydrozone. 32 75C -58 "Evapotranspiration adjustment factor" or "ETAF' means a factor of 0.7, that, when applied to reference evapotranspiration, adjusts for plant factors and irrigation efficiency, two major influences upon the amount of water that needs to be applied to the landscape. A combined plant mix with a site -wide average of 0.5 is the basis of the plant factor portion of this calculation. For purposes of the ETAF, the average irrigation efficiency is 0.71. Therefore, the ET Adjustment Factor is (0.7)= (0.5/0.71). ETAF for a Special Landscape Area shall not exceed 1.0. ETAF for existing non - rehabilitated landscapes is 0.8. "Evapotranspiration rate" means the quantity of water evaporated from adjacent soil and other surfaces and transpired by plants during a specified time. "Flow rate" means the rate at which water flows through pipes, valves and emission devices, measured in gallons per minute, gallons per hour, or cubic feet per second. "Hardscapes" means any durable material or feature (pervious and non pervious) installed in or around a landscape area, such as pavements or walls. Pools and other water features are considered part of the landscape area and not considered hardscapes for purposes of these Guidelines. "Graywater" means a system intreated wastewater that has not been contaminated by any toilet discharge, has not been affected by infectious, contaminated, or unhealthy bodily wastes, and does not present a flu eat from contamination by unhealthy processing, manufacturing, or operating wastes. Graywater includes, but is not limited to, wastewater from bathtubs, showers, bathroom washbasins, clothes washing machines. And laundry tubs, but does not include wastewater from kitchen sinks or dishwashers as per the Health and Safety Code (Section 17922.12). Graywater systems promote the efficient use of water and are encouraged to assist in on -site landscape irrigation. All graywater systems shall conform to the California Plumbing Code (Title 24, Part 5, Chapter 16) and any applicable local ordinance standards. "Hydrozone" means a portion of the landscape area having plants with similar water needs and typically irrigated by one valve /controller station. A hydrozone may be irrigated or non- irrigated. "Infiltration rate" means the rate of water entry into the soil expressed as a depth of water per unit of time (e.g., inches per hour). "Invasive" plants species or "noxious" means species of plants not historically found in California that spread outside cultivated areas and can damage environmental or economic resources. Invasive plant species may be regulated by county agricultural agencies as noxious species. "Irrigation audit" means an in -depth evaluation of the performance of an irrigation system conducted by a Certified Landscape Irrigation Auditor. An irrigation audit includes, but is not limited to: inspection, system tune -up, system test with distribution uniformity or emission uniformity, reporting overspray or runoff that causes overland flow, and preparation of an irrigation schedule. 33 75C -59 "Irrigation Management Efficiency" or "IMF" means the measurement used to calculate the irrigation efficiency of the irrigation system for a landscaped project. A 90% IME can be achieved by using evaportranspiration controllers, soil moisture sensors, and other methods that will adjust irrigation run times to meet plant water needs. "Irrigation efficiency" or "IE" means the measurement of the amount of water beneficially used divided by the amount of water applied to a landscape area.

"Master shut -off valve" an electronic valve such as a solenoid valve installed as close as possible to the point of connection and is used in conjunction with a flow sensor and flow monitoring controller technology to automatically shutdown system wide water flow in the event of high flow conditions such as mainline pipe break. "Maximum Applied Water Allowance" or "MAWA" means the upper limit of annual applied water for the established landscape area, as specified in Section 2.2 of these Guidelines. It is based upon the area's reference evapotranspiration, the ETAF, and the size of the landscape area. The Estimated Applied Water Use shall not exceed the Maximum Applied Water Allowance. "Microclimate" means the climate of a small, specific area that may contrast with the climate of the overall landscape area due to factors such as wind, sun exposure, plant density, or proximity to reflective surfaces. "Mulch" means any organic material such as leaves, bark, straw or compost, or inorganic mineral materials such as rocks, gravel, or decomposed granite left loose and applied to the soil surface for the beneficial purposes of reducing evaporation, suppressing weeds, moderating soil temperature, and preventing soil erosion. "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. "Operating pressure" means the pressure at which the parts of an irrigation system of sprinklers are designed to operate at by the manufacturer "Overspray" means the irrigation water which is delivered beyond the target area 35 75C -61 "D, erson" means any natural person, firm, joint venture, joint stock company, partnership, public or private association, club, company, corporation, business trust, organization, public or private agency, government agency or institution, school district, college, university, any other user of water provided by the City or the local water purveyor, or the manager, lessee, agent, servant, officer, or employee of any of them or any other entity which is recognized by law as the subject of rights or duties. "Pervious" means any surface or material that allows the passage of water through the material and into the underlying soil. "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 these Guidelines are derived from the Department of Water Resources 2000 publication "Water Use Classification of Landscape Species." "Precipitation rate" means the rate of application of water measured in inches per hour. "Project applicant" means the person submitting a Landscape Documentation Package required under Section 2.1 to request a permit, plan check, or design review from the local agency. A project applicant may be the property owner or his or her designee. "Property owner" or "owner" means the record owner of real property as shown on the most recently issued equalized assessment roll. "Reference evapotranspiration" or "ETV 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 C of these 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. "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. "Runoff' means water which is not absorbed by the soil or landscape to which it is applied and flows from the landscape 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 Landscape Areas" or "SLA" 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 community pools and spas, parks, sports fields, golf courses, and where turf provides a playing surface.

"Station" means an area served by one valve or by a set of valves that operate simultaneously. "Swing joint" means an irrigation component that provides a leak -free connection between the emission device and lateral pipeline to allow movement in any direction and to prevent equipment damage. Synthetic turf means an acceptable no now ground cover made of synthetic, no living material which meets the standards set forth in the City's Design and Development Standards. "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 Efficient Landscape Worksheets" means the worksheets required to be completed pursuant to Section 2.2 of these Guidelines and which are included in Appendix B hereof. "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 landscape 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" means the time of day irrigation is allowed. "WUCOLS" means the Water Use Classification of Landscape published by the University of California Cooperative Extension, the Department of Water Resources, and the Bureau of Reclamation, 2000. www. owue.water.ca.gov /docs /wuco1s00 37 75C -63 Appendix G: Irrigation Plan Checklist Tlus is a voluntary compliance tool template developed by the Irrigation Association.
