means areas related to production home neighborhoods, common interest developments, or other situations where multiple parcels are undergoing landscape development as one project, but may eventually be individually owned or maintained.

means the portion of water supplied by the irrigation system to the landscape.

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.

means a project where the site is intentionally altered to establish a defined, indigenous, historic ecosystem.

means the average annual total amount of water estimated to be necessary to keep plants in a healthy state, calculated as provided in the Submittal Requirements and 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.

is equal to the plant factor divided by the irrigation efficiency factor for a landscape project, as described in the Submittal Requirements and 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 landscape area.

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 this Chapter.

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 irrigation efficiency for purposes of this Chapter are 0.75 for overhead spray devices and 0.81 for drip systems.

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 landscape 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).

means a person licensed by the State of California to construct, maintain, repair, install, or subcontract the development of landscape systems.

means the documents required to be provided to the City for review and approval of landscape design projects, as described in the Submittal Requirements and Guidelines.

means a permit issued by the Community Development Department for the purposes of meeting the landscape area thresholds and design requirements under Section 9.55.020 of this Chapter and the corresponding Submittal Requirements and Guidelines.

means total area of landscape in a project, as provided in the definition of "landscape area," meeting the requirements under Section 9.55.020 of this Chapter.

means a city or county, including a charter city or charter county, that is authorized to implement, administer, and/or enforce any of the provisions of this Chapter. The local agency may be responsible for the enforcement or delegation of enforcement of this Chapter including, but not limited to, plan check, issuance of permits, and inspection of a landscape project.

means any entity, including a public agency, district, city, county, or private water company that provides retail water service.

means the upper limit of annual applied water for the established landscape area as specified in Section 2.2 of the Submittal Requirements and Guidelines. It is based upon the area's reference evapotranspiration, the ET adjustment factor, and the size of the landscape area. The Estimated Total Water Use shall not exceed the Maximum Applied Water Allowance. MAWA = (ETo) (0.62) [(ETAF x LA) + ((1-ETAF) x SLA)]

means any surface mining operation with a reclamation plan approved in accordance with the Surface Mining and Reclamation Act of 1975.

means, for the purposes of this Chapter, a new building with a landscape or other new landscape such as a park, playground, or greenbelt without an associated building.

means any surface or natural material that does not allow for the passage of water through the material and into the underlying soil.

means any surface or material that allows the passage of water through the material and into the underlying soil.

is a factor, when multiplied by ETo, that estimates the amount of water needed by plants. For purposes of this Chapter, the plant factor range for very low water use plants is 0 to 0.1; the plant factor range for low water use plants is 0.1 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 Chapter are derived from the publication "Water Use Classification of Landscape Species." Plant factors may also be obtained from horticultural researchers from academic institutions or professional associations as approved by the California Department of Water Resources (DWR).

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.

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 D of the Submittal Requirements and 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.

means any re-landscaping project that meets the applicability criteria of Section 9.55.020(a), where the modified landscape area is greater than 2,500 square feet.

means an automatic irrigation controller utilizing either evapotranspiration or soil moisture sensor data with non-volatile memory and shall be required for irrigation scheduling in all irrigation systems, recommending U.S. EPA WaterSense labeled devices as applicable.

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 recreational areas dedicated to active play such as parks, sports fields, golf courses, and where turf provides a playing surface.

refers to the Submittal Requirements and Guidelines for implementation of this Chapter, as adopted by the City, which describes procedures, calculations, and requirements for landscape projects subject to this Water Efficient Landscape Ordinance.

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.

means a device used to control the flow of water in an irrigation system.

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.
