PCWA FERC Middle Fork of the American River Relicensing

Placer County, CA

ANDREGG GEOMATICS assisted Placer County Water Agency (PCWA) in their Federal Energy Regulatory Commission (FERC) relicensing for the Middle Fork of the American River, located in remote portions of the Sierra Nevada Foothills of Placer County, California. 

Initial efforts consisted of developing and establishing a high accuracy GPS geodetic control network along approximately 40 miles of the project area. Efforts included redundant GPS observations of available high order horizontal and vertical control and digital leveling campaigns. Once this control network was constructed and control values were verified, aerial mapping and orthophotography across the entire project area were completed. Secondary facilities and hydrographic surveys were then commissioned and completed by ANDREGG.

Using available PCWA documents, deeds and recorded surveys, ANDREGG was able to develop a landnet for the entire project area with reference to the Public Land Survey System (PLSS). These efforts included outreach with public and private land owners and retracement of original Government Land Office (GLO) survey plats and notes. Assessment information for the parcels located within the FERC boundary was compiled into a GIS project database.

Working along with PCWA and other team members, ANDREGG completed final FERC submittals and is currently awaiting comments and additional licensing areas to be determined through the FERC review process.
