1.0 PROJECT DESCRIPTION SERVICE TO RECYCLED WATER TO OYSTER BAY REGIONAL PARK The City is proposing to provide disinfected tertiary recycled water to Oyster Bay Regional Park far irrigation. Oyster Bay Regional Park is a 157-acre park, owned and managed by the East Bay Regional Parks District (EBRPD), that was once a landfill (see Figures 1-2 and 1; 3). Part of the park has been developed into landscaped picnic areas, with benches and walkways, in addition the Bay Trail encircles the park, but most of the land is undeveloped. The park is crisscrossed with a network of dirt, gravel; and paved trails. The provision of recycled water to this park would involve: Constructing a recycled water disinfection and filtration facility at the WPCP; Constructing a pipeline to convey the recycled water to Oyster Bay Regional Park; and Installing an irrigation system at the park. PROPOSED RECYCLED WATER DISINFECTION AND FILTRATION FACILITY AT THE WPCP Similar to the water recycling plant for the Marina Park facilities, the treatment for the recycled water to be used at the Oyster Bay Regional Park would require approximately 800 gpm (1.15 mgd) filtration and ultra violet (LJV) disinfection capacity. This capacity assumes 24-hour treatment and storage in existing tanks at the WPCP. The disinfection and filtration facility would be at the WPCP, and would require approximately 400 square feet of space. STORAGE Recycled water storage for service to Oyster Bay Regional Park would use one or more empty tanks at the WPCP. A 2,400 gpm (3.5 mgd) above grade pump station to deliver recycled water from the storage facility to Oyster Bay during the irrigation period of approximately 10:00 p.m. to 5:00 a.m. would also be constructed. PROPOSED PIPELINE TO OYSTER BAY REGIONAL PARK The City is proposing to implement one of two pipeline alignments, referred to herein as the Northern Pipeline Route and the Southern Pipeline Route. Both routes are described below and analyzed in detail in this Initial Study/Mitigated Negative Declaration. The City's preferred alignment is the Northem Pipeline Route. Should construction of a proposed pedestrian bicycle bridge along this route be delayed such that its implementation would substantially delay the City's Water Recycling Project, the City would construct the pipeline along the Southern Pipeline Route. The City would install a water gun irrigation system for approximately 145 acres of Oyster Bay Regional Patk. San reandro Recyclcd Water Projcct 1-10 ESA / 7A3193 Dray 1SRvII~ID
