About this file
This document is a set of project plans and photos for the Pine Flat Dam Storm Debris Removal project located in Sanger, California. The documents include vicinity maps, site plans, and site photographs depicting a landslide risk reduction and monitoring project at the Pine Flat Dam site. Key details include:
The project involves rockfall and debris barrier installation, upper slope regrading, and tension crack repair. The site plan reveals specific project elements such as a construction access route, staging area, and project site coordinates (36°48'30"N, 119°20'21.53"W). The documents specify contractor requirements including improving existing access, restoring disturbed areas with hydroseeding, providing flexible couplings for displaced drainage pipes, and submitting a lift plan for equipment placement. The project is being conducted by the U.S. Army Corps of Engineers Sacramento District, with design work completed by AECOM Technical Services in June 2019.
