Document Description
Note: Review Per Lead The District proposes to implement the Wet Weather Equalization Expansion Project, which would modify the multi-purpose wet-weather equalization facility constructed as part of a previous project described and evaluated in the Wet Weather Equalization and Ecotone Demonstration Project IS/MND. The proposed project would deepen the existing wet-weather equalization basin to increase equalization capacity from 8-24 M gallons. The proposed project site consists of a 4.5-acre parcel located at 2536 Grant Ave in the community of San Lorenzo, unincorporated Alameda County, CA, adjacent to and east of the existing OLSD wastewater treatment plant.
