pervious hardscapes, and other non - irrigated areas designated for non - development (e.g., open <br />spaces and existing native vegetation). <br />"Lateral line" means the water delivery pipeline that supplies water to the emitters or sprinklers <br />from the valve. <br />"Low volume irrigation" means the application of irrigation water at low pressure through a <br />system of tubing or lateral lines and low volume emitters such as drip, drip lines, and bubblers. <br />Low volume irrigation systems are specifically designed to apply small volumes of water slowly <br />at or near the root zone of plants. <br />"Low volume overhead irrigation " means aboveground irrigation heads with an upper flow limit <br />of 0.5 GPM. <br />"Main line" means the pressurized pipeline that delivers water from the water source to the valve <br />or outlet. <br />"Manual Isolation Valve" means a valve such as a gate valve, ball valve, or butterfly valve <br />installed downstream of the point of connection of the water supply to shutdown water flow <br />through mainline piping for routine maintenance and emergency repair. <br />"Master shut -off valve" an electronic valve such as a solenoid valve installed as close as possible <br />to the point of connection and is used in conjunction with a flow sensor and flow monitoring <br />controller technology to automatically shutdown system wide water flow in the event of high <br />flow conditions such as mainline pipe break. <br />"Maximum Applied Water Allowance" or "MAWA" means the upper limit of annual applied <br />water for the established landscape area, as specified in Section 2.2 of these Guidelines. It is <br />based upon the area's reference evapotranspiration, the ETAF, and the size of the landscape <br />area. The Estimated Applied Water Use shall not exceed the Maximum Applied Water <br />Allowance. <br />"Microclimate" means the climate of a small, specific area that may contrast with the climate of <br />the overall landscape area due to factors such as wind, sun exposure, plant density, or proximity <br />to reflective surfaces. <br />"Mulch" means any organic material such as leaves, bark, straw or compost, or inorganic mineral <br />materials such as rocks, gravel, or decomposed granite left loose and applied to the soil surface <br />for the beneficial purposes of reducing evaporation, suppressing weeds, moderating soil <br />temperature, and preventing soil erosion. <br />"Non pervious" means any surface or natural material that does not allow for the passage of <br />water through the material and into the underlying soil. <br />"Operating pressure" means the pressure at which the parts of an irrigation system of sprinklers <br />are designed to operate at by the manufacturer <br />"Overspray" means the irrigation water which is delivered beyond the target area <br />35 <br />
