City of San Leandro <br />A-102 <br />22. All plans shall specify that 50 percent of landscape construction and demolition waste by <br />weight must be diverted from the landfill. <br />E. Recommended Design Standards. It is recommended that all landscape projects: <br />1. Protect and preserve existing native vegetation and use local natural plant communities <br />as models; <br />2. Select water-conserving plant and turf species that are suitable for the climate and soil <br />conditions in San Leandro; <br />3. Select plants based on disease and pest resistance; <br />4. Use the Sunset Western Climate Zone System to select plants, which takes into account <br />temperature, humidity, elevation, terrain, latitude, and varying degrees of continental and <br />marine influence on local climate; <br />5. Avoid turf on slopes greater than 10 percent where the toe of the slope is adjacent to an <br />impermeable hardscape and avoid turf in street medians, traffic islands or bulbouts of any <br />size unless irrigated with subsurface or low volume irrigation; <br />6. Grade so that all irrigation and normal rainfall remains within property lines and does not <br />drain on to non-permeable hardscapes; <br />7. Avoid disruption of natural drainage patterns and undisturbed soil; <br />8. Avoid soil compaction in landscape areas; <br />9. Place trees on separate valves from shrubs, groundcovers, and turf; <br />10. Use automatic irrigation controllers that allow for multiple start times; <br />11. Set irrigation controls to water before 10:00 a.m. or after 8:00 p.m.; <br />12. Space sprinkler heads to achieve a uniform precipitation rate with no overspray onto <br />hardscapes; <br />13. Use dedicated landscape water meters on landscape areas smaller than 5,000 square feet <br />to facilitate water management; <br />14. Install high-flow sensors (flow meters) that detect and report high flow conditions created <br />by system damage or malfunction; <br />15. Install manual shut-off valves (such as a gate valve, ball valve, or butterfly valve) as close <br />as possible to the point of connection of the water supply, to minimize water loss in case <br />of an emergency (such as a main line break) or routine repair; <br />16. Use low volume irrigation to maximize water infiltration into the root zone in mulched <br />planting areas; <br />17. Incorporate rain harvesting or catchment technologies such as cisterns for storage and <br />use of rainwater to satisfy a percentage of the landscape irrigation requirements; and <br />151
