7.A. - Page 2 State regulations and the ordinance no longer sufficiently prepares Redwood City for water shortage emergencies or address all the prohibitions enacted by the State. Public Works has developed a Water Shortage Contingency Plan consistent with the requirements set forth by the California State Water Code including permanent prohibitions on specific potable water uses regardless of water supply conditions. These prohibitions include: 1. The application of potable water to outdoor landscapes in a manner that causes runoff such that water flows onto adjacent property, non-irrigated areas, private and public walkways, roadways, parking lots, or structures; 2. The use of a hose that dispenses potable water to wash a motor vehicle, except where the hose is fitted with a shut-off nozzle or device attached to it that causes it to cease dispensing water immediately when not in use; 3. The application of potable water to driveways and sidewalks; 4. The use of potable water in a fountain or other decorative water feature, except where the water is part of a recirculating system; 5. The application of potable water to outdoor landscapes during and within 48 hours after measurable rainfall; 6. The irrigation with potable water of ornamental turf on public street medians; 7. The irrigation with potable water of landscapes outside of newly constructed homes and buildings in a manner inconsistent with regulations or other requirements established by the California Building Standards Commission and the Department of Housing and Community Development. 8. Use of potable water through broken or defective plumbing and irrigation systems. In addition to the State mandated prohibitions and consistent with other water agencies in the region, staff has included the use of potable water in single-pass cooling systems as a prohibited action. This will improve water use efficiency and prevent the unreasonable waste of potable water. In an improvement from Ordinance No. 2062, which had no stages of action defined for increased levels of water shortage, the WSCP has five stages of actions to mitigate the effects of water shortages. • Stage 1 water shortage (up to ten (10) percent reduction). • Stage 2 water shortage (up to fifteen percent reduction). • Stage 3 water shortage (up to twenty percent reduction). • Stage 4 water shortage (up to thirty percent reduction).
