"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. "Person" 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 Standards 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 maybe 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 "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 C of these Standards, 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. 75A-59
