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 chapter except that the ETAF for a special landscape area shall not exceed 1.0.

"Infiltration rate"means the rate of water entry into the soil expressed as a depth of water per unit of time (i.e., inches per hour).
"Invasive species"means nonindigenous species that adversely affect the habitats they invade economically, environmentally, or ecologically.
"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.
"Irrigation efficiency"means the measurement of the amount of water beneficially used divided by the amount of amount applied. Irrigation efficiency is derived from measurements and estimates of irrigation system characteristics and management practices. The minimum irrigation efficiency for purposes of this chapter is 0.71.
"Landscape architect"means a person licensed to practice landscape architecture in this state pursuant to Chapter 3.5 (commencing with Section
5615) of Division 3 of the Business and Professions Code.
"Landscape concept plan"means the portion of a landscape documentation package that includes a design statement, irrigation notes, planting notes, the plant palette, and conforms with the requirements of this chapter.
"Landscape construction drawings"means the portion of a landscape documentation package that includes the irrigation plan, plant and soils plan, water management plan, and conforms with the requirements of this chapter.
"Local water purveyor"means any entity, including a public agency, city, county or private water company that provides retail water service.
"Low head drainage"means drainage from a sprinkler that is caused by water flowing down an irrigation system from a higher level of elevation.
"Low water use plants"mean Mediterranean region and native trees, shrubs and groundcovers and other plants recognized as low-water-use by the Water Classification of Landscape Species document as available from the state of California as it currently exists or may be amended in the future.
"Maximum applied water allowance" or "MAWA"means the upper limit of annual applied water for the established landscaped area. 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.
"Moderate water use plants"mean ornamental trees, shrubs, groundcovers, perennials, and other plants recognized as moderate-water-use by the Water Classification of Landscape Species document as available from the state of California as it currently exists or may be amended in the future.
"Mulch"means any organic material such as leaves, bark, or inorganic material such as pebbles, stones, gravel, decorative sand or decomposed granite left loose and applied to the soil surface to reduce evaporation.
"Operating pressure"means the pressure at which an irrigation system of sprinklers is designed by the manufacturer to operate, usually indicated at the base of a sprinkler.
"Overspray"means the water that is delivered beyond the landscaped areas by the irrigation system onto pavements, walks, structures, or other non-landscaped areas.
"Planting plan"means a plan submitted with the construction drawings indicating a list and quantity of plants.
"Potable water"means water meant for human consumption that is treated to legal standards for human consumption.
"Project net landscape area," "landscaped area," or "landscape project area"means all of the planting areas, turf areas, and water features in a landscape design plan subject to the maximum applied water allowance calculation. The landscape area does not include footprints of buildings or structures, sidewalks, driveways, parking lots, decks, patios, gravel or stone walks, other previous or nonpervious hardscapes, and other nonirrigated areas designated for nondevelopment.
"Rain sensor"means a system component that detects rainfall and automatically overrides the irrigation system during rain events.
"Recycled water"means water which, as a result of treatment of waste, is suitable for a direct beneficial use or a controlled use that would not otherwise occur and is therefore considered a valuable resource. Recycled water shall not be intended for human consumption.
