Capital Improvement Project

Los Alamos Trunk Replacement: Streamside Dr to Elaine Dr

Estimated Construction Schedule: Slated to begin July, 2020 and is anticipated to be completed January, 2022.
Construction Contract Amount: Pending
Project ID #: 1903
Description: This project includes providing the preliminary design and supporting studies for replacement of the existing Los Alamos sewer trunk from Streamside Drive to Melita Drive (approximately 16,000 linear feet (LF)). Construction documents will be prepared for the downstream segment (approximately 5,500 LF) from Streamside Drive to Elaine Drive. The trunk, installed in the 1950's is undersized and is in poor condition. This project will provide more capacity to help prevent overflows, increase reliability, and reduce maintenance. In addition, it will be re-aligned out of yards and further away from the creek where practical. Relocation of the water main may be necessary in certain locations to create adequate separation from proposed sewer line.

Questions regarding connecting to public sewer, and Design update: For questions regarding connecting to public sewer please contact: Celia Parkinson (707-543-4522) or Shelli Allen (707-543-4336). CEQA approved. Right of Way (easements) are in the process of being obtained.
