<br />mon areas of common interest developments with designated recreation-
<br />al areas.
<br />(aaa) "operating pressure" means the pressure at which the parts of an
<br />irrigation system are designed by the manufacturer to operate.
<br />(bbb) "overhead sprinkler irrigation systems" or `overhead spray ir-
<br />rigation systems" means symems that deliver water through the air (e.g.,
<br />spray heads and rotors).
<br />(ccc) "overspray" means the irrigation water which is delivered be-
<br />yond the target area.
<br />(ddd) "parkway" means the area between a sidewalk anti the curb or
<br />traffic lane- It may be planted or unplanted, and with or without pedes-
<br />trian egress.
<br />(eee) "permit" means an authorizing document issued by local agen-
<br />cies for new construction or rehabilitated landscapes.
<br />(fll) "pervious" means any surface or material that allows the passage
<br />of water through the material and into the tmderlying soil.
<br />(ggg) "plant factor" or "'plant water use factor" is a factor, when multi-
<br />plied by ETo, estimates the amount of water needed by plants. For pur-
<br />pose% of this ordinance,. the plant factor range for very low water use
<br />plants is 0 to 0. 1, the plant factor range for low water use plants is 0.1 to
<br />0.3, the plant factor range for moderate water use plants is 0.4 to 0.6, and
<br />the plant factor range for high water use plants is 0.7 to 1.0. Plant factors
<br />cited in this ordinance are derived from the publication "Water Use Clas-
<br />sification of Landscape Species". Plant factors may also be obtained
<br />from horticultural researchers from academic institutions or professional
<br />associations as approved by the California Department of Water Re-

<br />(kkk)"recreatiopal area" means amus, excluding private single family
<br />residential areas, designated for active play, recreation or public assem-

<br />water" means treated or recycled waste water of a quality suitable for
<br />nonpotablc us" such as landscape irrigation and water features. This wa-
<br />ter is not intended for human consumption.
<br />(mmm) "reference evapotranspiration"' or "ETo" Means a standard
<br />measurement of environmental parameters which affect the water use of
<br />plants- ETo is expressed in inches per day, month, or year as represented
<br />in Appendix A, and is an estimate of the evapotranspiration of a large
<br />field of four- to seven-inch tall, cool -season grass that is well watered.
<br />Reference evapotranspiration is used as the basis of determining the
<br />Maximum Applied Water Allowances so that regional differences in cli-
<br />mate can be accommodated.
<br />(nun) "Regional Water Efficient Landscape Ordinance" means a local
<br />Ordinance adopted by two or more local agencies, water suppliers and
<br />other stakeholders for implementing a consistent set of landscape provi-
<br />sions throughout a geographical region. Regional ordinances are strong-
<br />ly encouraged to provide a consistent framework for the landscape indus-
<br />try and applicants to adhere to.
<br />(000) "rchahilitated landscape- medals any relandscaping project that
<br />requires a permit, plan check, or design review, meets the requirements

<br />(ppp) "residential landscape" means landscapes surrounding single or
<br />multifamily homes.
<br />(qqq) "tun off' means water which is not absorbed by the soil or land-
<br />scape to which it is applied and flows from the landscape area. For exam-
<br />ple, run off may result from water that is applied at too great a rate (appli-
<br />cation rate exceeds infiltration rate) or when there is a slope.
<br />(rrr) "sail moisture sensing device" or "soil moisture sensor" cleans
<br />a device that measures the amount of water in the soil. The device may
<br />also suspend or initiate an irrigation event.
<br />(sss) "soil texture" means the classification of soil based on its percent-
<br />age of sand, silt, and clay.
<br />(ttt) "Special Landscape Area" (SLA) means an area of the landscape

<br />(vvv) "static water pressure" means the pipeline or municipal water
<br />supply pressure when water is not flowing.
<br />(www) "station" means an area served by one valve or by a set of
<br />valves that operate simultaneously.
<br />(xxx) "swing joint" meteor an irrigation component that provides a

<br />(cccc) "water feature"' means a design element where open water per-
<br />form an acstlictic or recreational function. Water features include ponds,
<br />lakes, waterfalls, fountains, artificial streams, spas, and swimming pools
<br />(where water is artificially supplied). The surface area of water features
<br />is included in the high water use hydrozone of the landscape area.
<br />Constructed wetlands used foron-site wastewater treatment orstonnwa-
<br />ter best management practices that are not irrigated and used solely for
<br />water treatment orstormwater retention are not water features and, there-
<br />fore, are not subject to the water budget calculation.
<br />(dddd) "watering window" Mans the time of day irrigation is allowed.
