Capital Improvement Project

Fulton Rd Sewer Main Improvements West 3rd St to Santa Rosa Creek

Estimated Construction Schedule: Slated to begin June, 2024 and is anticipated to be completed December, 2024.
Construction Contract Amount: Pending
Project ID #: 2117
Description: Eliminate the constrictions in the existing sewer pipe across Santa Rosa Creek between manhole 12 and manhole 13. The existing 18-inch ACP sewer was installed in 1969 under the creek and west of the Fulton Road bridge. The 18-inch ACP sewer was lined with a 14-inch polyethylene (PE) liner in 1985. CCTV video indicates that the PE liner is deformed creating constrictions. Open-cut replacement with a new 8-inch diameter pipe was the method recommended by the consultants RMC/Woodward & Curran in their Technical Memorandum dated February 26, 2018. A cofferdam, fish relocation, and construction area creek flow bypass will likely be necessary.

Spring-Summer 2023: IS/MND anticipated to be before BPU for approval in July 2023. CEQA documents (Initial Study Mitigated Negative Declaration) available on this public web site.
