Document Description
The proposed project includes a multi-purpose wet-weather equalization facility that will include both a treatment wetland and an upland ecotone slope for polishing of treated wastewater. The facility will accommodate infrequent peak wet-weather flows, and provide an opportunity to pilot several adaptation strategies related to sea level rise, water quality protection, and infrastructure sustainability. The project site consists of a fifteen-acre parcel located at 2536 Grant Avenue in the community of San Lorenzo, unincorporated Alameda County, CA, sited adjacent to and east of the existing OLSD wastewater treatment plant.
