Water Resources Development & Impact Evaluation

Surface Water and Water Supply Projects, Stanislaus, San Joaquin and Merced Counties, CA

JJ&A has assisted several clients with consultation regarding major proposed water resources or supply projects on regulations that could adversely affect their water supplies. For example, we led a team of consultants, attorneys, and local officials from Stanislaus, San Joaquin and Merced Counties to compile comments to the State Water Resources Control Board (SWRCB) on its CEQA-equivalent environmental review of proposed amendments to the Bay-Delta Water Quality Control Plan that require 40 to 60 percent of unimpaired flows on the Stanislaus, Tuolumne and Merced Rivers. These requirements would have far reaching water supply and management impacts throughout the region, including more limited municipal and agricultural water supply availability, and would pose major challenges to the region’s

ability to comply with the requirements of the Sustainable Groundwater Management Act (SGMA). We led the team in preparing comments regarding potential impacts to groundwater resources and supplies, and compiled a single document with comments that also considered potential impacts to agriculture, water utilities, disadvantaged communities and schools.

For the City of Marina, JJ&A reviewed and commented to the California Public Utilities Commission (CPUC) on the Environmental Impact Statement/Environmental Impact Report (EIS/EIR) for the proposed Monterey Peninsula Water Supply Project, a major proposed desalination project. We reviewed project data, hydrogeologic studies and geophysical investigations of the subsurface water quality and stratigraphy of the region, and prepared several expert reports. Our reports demonstrated the project would exacerbate seawater intrusion into the City’s water supply aquifers, and that the EIS/EIR for the proposed project had not adequately considered all of the available information, addressed potential cumulative effects, or considered potential project effects on local water supply protection or compliance with the SGMA. In addition, the percentage of freshwater that would be withdrawn from local aquifers for desalination plant makeup water was greatly underestimated.

The repairs you and your team completed far exceeded my expectations. The project team will be pleased that this was addressed before the bulk of the weekend rainfall. Thank you for the great work and completing it on such short notice.

…provides high consistency quality work. By ensuring that inconsistencies are ironed out before my review, I can easily provide comments on the content rather than structure.

…to the project team that best exemplifies our vision and values…with excellent execution, in a way that enhances the community and creates value.” ER Department Award of Excellence
