2025 Urban Water Management Plan

City of Pleasanton | Water Shortage Contingency Plan Public Draft | May 2026 12 EKI Environment & Water, Inc. 4.4 Additional Mandatory Restrictions The City defines wasteful water use as a violation of water service and enforces the restrictions listed below under PMC §14.04.060 and related code provisions. The City’s current definitions of wasteful water 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, and/or 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. 8. Any use of potable water in violation of the CWC, including, but not limited to, the use of potable water on non-functional turf. 4.5 Emergency Response Plan The shortage stages in Table 3 apply to both foreseeable and unforeseeable water supply shortage conditions. For catastrophic events, the City will implement the Water Emergency Response Plan (ERP) and coordinate emergency declarations and response actions with City leadership and Zone 7. The City’s Water ERP specifies that the City Council, the Director of Emergency Services (City Manager), and the Director of Public Works have the authority to proclaim a Local Water Emergency. In a water emergency, the City would activate a Water Emergency Operations Center (WEOC), with partial or full staffing dependent on the magnitude of the event. WEOC and other emergency support staff and departments would typically work under the direction of the Director of Emergency Services (i.e., the City Manager). As defined in the City’s Water Management Plan, if there were a major failure of supply, storage or facility distribution, a declaration of mandatory water use restrictions would be necessary in designated affected areas (expected reduction would vary in response to the specific situation). The City will also follow the lead of Zone 7, or the State of California, during a major catastrophe or drought period. When Zone 7 announces a curtailment in water deliveries, the City will assess the impact on the City supplies and determine its water shortage level. The City will monitor the situation closely, both from a supply and demand perspective, and carefully select the appropriate shortage response actions to close the gap between anticipated supplies and demand. The City will move from one stage to the next if the situation worsens and will reduce restrictions when it subsides. To provide supplies during
