PAGE 9 Landscaped area means the entire parcel less the building foot- print, driveways, non-irrigated portions of parking lots, hard- scapes such as decks and patios, and other non-porous areas.

Lateral line means the water delivery pipeline that supplies water to the emitters or sprinklers from the valve. Main line means the pressurized pipeline that delivers water from the water source to the valve or outlet. Maximum Applied Water Allowance (MAWA) means the maximum amount of water allocated to a project based on the following formula: MAWA=(ETo) (0.8) (L~) (0.62), where MAWA=Maximum Applied Water Allowance (gallons per year) ETo=Reference Evapotranspiration (inches per year) 0.8=ET Adjustment Factor LA=Landscaped Area (square feet) 0.62=Conversion Factor (to gallons per square foot) "Mediterranean-type" plants means plant materials native to other regions of the world with similar climate conditions to those found in Santa Aha. The majority of these plants are able to readily adapt to Santa Ana growing conditions. Moisture sensor means a device that can measure the condition of the moisture in the soil and over ride the control device for watering purposes. Mulches mean organic materials that serve as an insulation layer on the soil surface to moderate soil temperature and reduce the rate of water loss (evaporation) into the air. Native plants means California plant materials that have adapted or evolved in plant communities or ecosystems under the climatic conditions found in Santa Ana. Non-turf areas mean areas using other that grass such as trees, shrubs, or ground covers but limited to living plant material Operating pressure means the pressure at which a system of sprinklers is designed to operate, usually indicated at the base of the sprinkler. 9
