Present Land Use
The project area is located in portions of the Cities of Pleasanton and Livermore, and portions of unincorporated Alameda County. Within the City of Pleasanton, well fields are located in Residential, Commercial / Industrial, Open Space, Community Uses. Livermore land uses include Open Space / Agricultural, Public Uses, Vacant Public Uses, Vacant BCP and Development Commercial. The unincorporated portions of Alameda County are currently used as a quarry and gravel mining areas.

Document Description
The proposed project is to recover groundwater that has been stored under Zone 7's conjunctive use program at the appropriate rate to meet its reliability goals. In order to do this, Zone 7 proposes to increase its well production capacity by up to 42 million gallons per day (mgd) through the installation of 8 to 15 new production wells. The proposed project would provide 20 mgd of additional sustainable capacity to meet drought year demands, and would provide up to an additional 42 mgd of peak capacity to meet emergency demands. Based upon projected demands, it is anticipated that the wells would be installed over a period of approximately 20 years, with an average of one or two wells being constructed every one to two years, on an as-needed basis. Zone 7 proposes to construct additional well capacity within the Main Basin in order to meet its reliability goals at demand levels associated with 2020 build out within its service area.
