January 11, 2016 <br />Efficiency of Landscape Species (WUCOLS) Species Evaluation List or <br />from horticultural researchers with academic institutions or professional <br />associations as approved by the California Department of water Resources <br />(DWR). The plant factor ranges from 0 to 0.1 for very low water use <br />plants, 0.1 to 0.3 for low water use plants, 0.4 to 0.6 for moderate water <br />use plants, and 0.7 to 1.0 for high water use plants. <br />(5) For calculating the EAWU, the plant water use factor shall be determined <br />for each valve hydrozone based on the highest- water -use plant species <br />within the zone. The plant factor for each hydrozone may be required to <br />be further refined as a "landscape coefficient," according to protocols <br />defined in detail in the WUCOLS document, to reflect planting density and <br />microclimate effects on water need at the option of the project applicant <br />or the City. <br />(6) For calculation of the EA UV, the area of a water feature shall be defined <br />as a high water use hydrozone with a plant factor of 1.0. <br />(7) For calculation of the EAWU, a temporarily irrigated hydrozone area, such <br />as an area of highly drought- tolerant native plants that are not intended to <br />be irrigated after they are fully established, shall be defined as a very low <br />water use hydrozone with a plant factor of 0.1. <br />(8) For calculation of the MAWA, the ETAF for Special Landscape Areas <br />(SLA) shall be set at 1.0. For calculation of the EAWU, the ETAF for SLA <br />shall be calculated as the SLA plant factor divided by the SLA irrigation <br />efficiency factor. <br />(9) Irrigation efficiency (IE) of the irrigation heads used within each <br />hydrozone shall be assumed to be as follows, unless otherwise indicated <br />by the irrigation equipment manufacturer's specifications or demonstrated <br />by the project applicant: <br />Irrigation Method <br />DULQ <br />DULH* <br />EU <br />IE ** <br />Spray nozzles <br />65% <br />79% <br />71% <br />High efficiency spray nozzles <br />70% <br />82% <br />73% <br />Multi stream/Multi trajectory <br />rota MSMT) nozzles <br />75% <br />85% <br />76% <br />Stream rotor nozzle <br />70% <br />82% <br />73% <br />Microspray <br />75% <br />85% <br />76% <br />Bubblers <br />1 <br />1 85% <br />1 77% <br />Drip emitter <br />90% <br />81% <br />Subsurface drip <br />90% <br />81% <br />*DULH =.386 + (.614)(DULQ <br />** IE (spray) _ (DULH)(IME) <br />** IE (drip) = Emission uniformity (EU)(IME) <br />6 <br />
