The City of Claremont General Plan Land Use Element designates the pump location as "Low Density Residential," and the Spreading Grounds as "Open Space." The portion of the Spreading Grounds in the City of Upland is also designated "Open Space" by the City's General Plan.

Document Description
The proposed project is a conjunctive use groundwater management project that will increase the reliability and reduce the cost of water supply within the Six Basins Area. The proposed project will supplement the storage and extraction of groundwater to manage groundwater levels in the Upper Claremont Heights basin. To do this the District proposes to construct infrastructure necessary to spread imported water that is in excess of current consumptive demand ("surplus water"). The purpose of this will be to recharge groundwater levels through a means other than relying on rain water which is frequently in short supply in this region, and then construct a production well to extract the groundwater so that it can be distributed to water retailers within the District's service area, when the water is not being extracted by the purveyors within the Six Basins adjudication. The extraction well will blend groundwater with treated surface water from the Miramar Treatment Plant and will also be used to help control rising groundwater "down basin" if necessary.
