41" AND CABRILLO WATER SUPPLY ASSESSMENT AUGUST 21, 2020 The City has several water demand reduction requirements and resources on their website that informs its customers on how to save water. Some of the main requirements are summarized below: • Residential o Mandatory 3% reduction in water use compared to usage during the some billing period in 2013. o Outdoor watering is restricted to no more than every other day or Mondays, Thursdays and Saturdays, and only between the hours of 6 p.m. and 6 a.m.* o Leaks must be repaired within 48 hours of notification by the City. o No washing down sidewalks or driveways. o No excessive water flow or runoff that causes water to flow onto an adjoining sidewalk, driveway, street, alley, gutter or ditch. o No washing vehicles with a hose, unless the hose is fitted with a shut-off nozzle. o No operating a fountain or decorative water feature, unless the water is part of a recirculating system. o No outdoor watering during and 48 hours following measurable rainfall. • Businesses o Restaurants, cafes and bars can only serve water to customers on request. o Hotels and motels must prominently display a notice providing guests with the option of choosing not to have towels and linens laundered daily. In addition, landscape policies have also been modified to allow drought tolerate landscape throughout the City (see Appendix B). These programs have been successful in reducing water demands throughout the City's service area. OCWD is also taking strides to ensure local water supplies will meet growing demands now and into the future. As mentioned, OCWD manages the City's groundwater supply and the entire OC Basin utilizing the BPP approach. In 2013, OCWD's Board of Directors adopted a policy to establish a stable BPP with the intention to work toward achieving and maintaining a 75 percent BPP by FY 2015-1 6. Although BPP is set at 75 percent, based on discussions with OCWD a conservative BPP of 70 percent is assumed through 2040 for supply projection analysis in the City's 2015 UWMP. Principles of this policy include: • OCWD's goal is to achieve a stable 75 percent BPP, while maintaining the same process of setting the BPP on an annual basis (BPP will be set in April of each year after a public hearing has been held and based upon the public hearing testimony, presented data, and reports provided at that time). • OCWD's transition to the 75 percent BPP was due to construction of the GWRS Initial Expansion Project, which was completed in 2015. This expansion provided an additional 31 ,000 AFY of water for recharging the groundwater basin. • OCWD must manage the OC Basin in a sustainable manner for future generations. The BPP will be reduced if future conditions warrant the change. FUSCOE ENGINEERING, INC. 55D-30 22
