This is a pothole report documenting subsurface utility locating and mapping services for the Jamacha Force Main & Gravity Main Sewer Improvements project in Spring Valley, California, prepared by C Below on behalf of Black & Veatch for the client. The project, identified as C Below Project No. 20-2959, involved comprehensive potholing and utility identification along Jamacha Boulevard from Sacramento Avenue to the Jamacha Pump Station. The scope of work included 33 pothole excavations and utility exposures performed between February 11 and February 26, 2021, conducted by technicians Justin Soliz, Roy Rutledge, and Elijah Keane. The potholing work identified and documented multiple utility lines including water mains ranging from 1 to 20 inches, gas lines (primarily 36-inch wrapped steel and smaller diameter plastic lines), sewer lines (8 to 12-inch ACP and PVC), electrical conduits, and communications lines. Each pothole location was precisely mapped with coordinates, measurements from ground surface to utility top depth, direction of utility flow, and physical tie information referencing permanent fixtures such as street signs, valve lids, and manhole covers.

The report documents significant subsurface challenges encountered during excavation, including hard slurry-type soil conditions that limited excavation depth at multiple locations, water table conditions at approximately 6 feet deep near address 9605, and dense soil compositions that prevented complete utility exposure in several instances. Several pothole locations identified multiple utilities at the same site, requiring additional satellite potholing to fully expose intersecting or parallel utilities. The report includes detailed profile views, photographic documentation, and specific comments regarding utility conflicts, such as a 12-inch force main sewer crossing a 6-inch water line at Ramona Avenue and parallel utility runs at La Presa Avenue. Two dry holes were encountered with no utilities found, and several locations documented unknown utilities or encasements that could not be definitively identified. All findings were georeferenced with GPS coordinates and tied to permanent site features to facilitate future design and construction planning for the sewer improvements project.
