ANDREGG GEOMATICS provided all surveying and mapping functions for the design of the pump station and restoration of the American River channel at the Auburn Dam site. Hired by Placer County Water Agency (PCWA), ANDREGG's critical tasks involved the timely verification of numerous existing conditions surveys and mapping of the submerged river channel was performed upstream and downstream of the Coffer Dam. Digital terrain models were prepared for submerged surfaces.
ANDREGG used a combination of state of the art technology along with well-established proven methods to acquire detailed design and analytical information for the project. State of the art technologies used included reflectorless total stations, GPS integrated hydrographic echo sounders, resource, geodetic and RTK GPS and digital color imagery and photogrammetric mapping.
