Sewer Project General Background

Central Contra Costa Sanitary District - Grayson Creek Truck Line Project - This is a Central Contra Costa Sanitary District (CCCSD) major rehabilitation project and not a City funded project that will take place over the next 12 months.

The City is coordinating permit work activities with CCCSD which is expected to begin construction of the Grayson Creek Trunk Line Project on Wednesday, June 8, 2016. Mountain Cascade, Inc. (CCCSD hired contractor) will begin the installation of a new sewer main at the Contra Costa Canal on Westover Drive, between Westover Lane and Maureen Lane.

The work will be performed via the tunneling method and is expected to be completed in late June 2016. Construction activities will include traffic control, excavation, shoring, installation of the new pipe, and backfill. In order to complete this work, the southern lane/shoulder along Westover Drive at the trail will be closed during this phase of work. Traffic delays are anticipated during peak commute hours.
