           institutions or professional associations as approved by the California Department of Water

         Resources (DWR). The plant factor ranges from 0 to 0.1 for very low water using plants, 0.1 to 0.3 for

        low water use plants, from 0.4 to 0.6 for moderate water use plants, and from 0.7 to 1.0 for high

         water use plants.

             (2)   All water features shall be included in the high water use hydrozone and temporarily irrigated

         areas shall be included in the low water use hydrozone.

             (3)   All special landscape areas shall be identiWed and their water use calculated.

       management practices that are not irrigated and used solely for water treatment or stormwater

          retention are not water features and, therefore, are not subject to the water budget calculation.

          manifold.

(13) The irrigation system shall be designed to prevent runo[, low head drainage, overspray, or
