Title

Sewer Highway Crossings Retrofit Project

Description

The Sewer Highway Crossings Retrofit Project would replace three existing gravity sewer lines across McKinleyville that cross under U.S. 101 with pipes that are more resilient to damage in a major earthquake and with a slightly larger capacity to handle larger storm event flows than the existing pipes. Specifically, the pipes would be replaced with parallel High Density Polyethylene (HDPE) pipe or Fusible Polyvinyl Chlorine (FPVC) pipe. The proposed replacement method for each highway crossing is Horizontal Auger Boring. The three Project sites total approximately 15.2 acres.
