City of Pleasanton Recycled Water Project CEQA Addendum • Vineyard Demand Factor - 0.33 AFY/acre • Landscaping Demand Factor - 2.5 AFY/acre • Vineyard Irrigation hours (Summer) 6am — 6pm • Landscape Irrigation hours (Summer) 6pm — 6am • Summer storage filling 6pm — 6am • Winter storage filling 24 hours per day By irrigating using the above scheduling, peak flows are reduced and pipe sizing is optimized. For more detailed information about the water master concept refer to the 2013 City of Pleasanton Recycled Water Feasibility Report. Maintenance procedures will include 1 or 2 existing City workers who will routinely inspect the pipeline alignments and connections for leaks and repair facilities on an as needed basis as well as conduct scheduled preventative maintenance procedures to keep the facilities in good working order. 2.4 Proposed Project Changes Since the IS/MND was adopted on September 16, 2014, most of the Project facilities have been constructed. However, the City is considering adding a water booster pump station at the Ken Mercer Sports complex in order to have sufficient water supply pressure to irrigate the fields at the sports park/facility. The Proposed Project change would consist of the installation of a City -furnished prepackaged water booster station, including approximately 300 -feet of new 16 -inch and 12 -inch recycled water main, approximately 130 -feet of 5 -inch electrical conduit and 2 PG&E vaults, sidewalk and building pad, and other associated works at the Ken Mercer Sports Complex.
