Marshall Street Capacity Improvement/Repair & Rehabilitation Project (2018-01)

Project Description:
The Marshall Street Capacity Improvement/Repair & Rehabilitation Project will consist of spot repairs and line replacements throughout CVSan and upsizing the trunk sewer main located on Marshall Street and Vincent Court.

The Marshall Street and Vincent Court portion of the project will consist of upsizing approximately 2,125 LF of existing 10” vitrified clay pipe (VCP) to 12” high-density polyethylene (HDPE), which will allow the trunk sewer main to accommodate peak wet weather flows. A 6” VCP sewer main on Marshall Street that runs parallel will also be abandoned and combined to the new 12” line. This section of the project will be located on Marshall St. between the Veronica Avenue and Greenacre Road intersections, and along an easement into Vincent Court.

Other project locations on public right of way include:

  • Grove Way between Morales Street and Virgil Street.
  • Center Street between Nash Way and Elaine Court.
  • Baker Road between Castro Valley Boulevard and Kerr Street.
  • Ione Avenue between Idena Avenue and Young Avenue.
  • Crow Canyon Road between Manter Road and Justco Lane.
  • Wisteria Street between Ganic Street and Somerset Avenue.
