The City of Santa Cruz (City) Water Department is considering to further develop riverbank filtration (RBF) operations. at the San Lorenzo River to augment existing surface diversions for the benefit of improved water quality, and reliability of water supply. In doing so, the City is proposing to conduct an RBF study to investigate hydrogeologic conditions within the alluvial aquifer along the San Lorenzo River at three general locations (Plate 1); the City's Tait Well parcel, east of the Santa Cruz Metro Station, and Santa Cruz Memorial. Additionally, the project would include work along and within the San 'Lorenzo River. Proposed work would include the construction of new monitoring wells, installation of temporary monitoring stations within the San Lorenzo River, and geophysical surveys.

The City has coordinated with property owners and intends to notify land owners in advance of access, or initiating work activities: Data collected would be used in a feasibility screening of locations, methodology, and design for the City's potential future development of RBF on the San Lorenzo River to augment existing surface water diversions for the benefit of improved intake water quality.
