THE CITY OF Water Shortage Contingency Plan rLEASANTON. 4.2 Additional Mandatory Restrictions The City protects and preserves the community water supply by defining wasteful water use as a violation of water service. Per PMC §14.04.060, the City's current definitions of water waste include: 1. Use of potable water between 9:00 a.m. and 6:00 p.m. to irrigate grass, lawns, groundcover, shrubbery, crops, vegetation, and trees, with the exception of hand watering and drip irrigation. 2. The application of potable water to outdoor landscaping 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. 3. Use of potable water to irrigate outdoor landscaping during and within 48 hours after measurable rainfall. 4. Use of potable water to wash down sidewalks, walkways, driveways, parking lots, open ground or other hard surface areas by the direct application of water thereto, unless needed for health or safety reasons. 5. Use of potable water in non -recirculating decorative ponds, fountains and other water features, with the exception of child water -play features. 6. Allowing potable water to escape from breaks within the person or consumer's plumbing system for more than eight hours after the person or consumer is notified or discovers the break. 7. Use of potable water for outdoor landscaping through a dedicated irrigation meter within the city's recycled water use area unless exempted by the director of operations and water utilities for existing water customers, or city engineer for new development. These restrictions are in addition to State -mandated prohibitions. 4.3 Supply Augmentation and Other Actions Chapter 6 of the City's 2020 UWMP describes the City's normal supply portfolio, which includes purchased treated water from Zone 7 and local groundwater. While Zone 7 has its own supply augmentation options, increased groundwater pumping is the City's only such option. Per its water supply contract with Zone 7, the City has a groundwater pumping quota (GPQ) of 3,500 acre-feet per year (AFY), with the possibility of carrying over up to 700 AFY of unused GPQ from the previous year. To exceed its GPQ the City would have to coordinate with Zone 7. Table 6 lists this supply augmentation method, which the City would use during Stage 6 (i.e., greater than 50 percent shortage).
