Title

Pipeline Rehabilitation W-1

Description

The project will rehabilitate approximately 21,965 linear feet (14.6 miles) of existing 8-inch sewer pipeline primarily within the paved right of way that includes rehabilitating 17 manholes (MHs), replacement of 4 MHs, installation of 17 new cleanouts, and performance of 12 pipeline point repairs. The rehabilitation of the pipelines would be achieved with either a cured-in-place pipe liner, or a ribloc (spiral) liner. Project components that were found to be located within a sensitive cultural resource area that had been recorded as a prehistoric village were removed from the Project and the Project scope was reduced in order to avoid the sensitive cultural resources. All excavations will occur primarily over existing pipeline trenches, and in previously disturbed soil. In all instances, the project combined with the revised scope has been identified to occur in areas classified as 'non-sensitive.'
