Notice of Intent to Adopt a Mitigated Negative Declaration-Work Order 4241
Helix Water District Pipeline Project 4241-Draft Initial Study-Mitigated Negative Declaration-November 30, 2017
In late September, the San Diego County Water Authority will begin rehabilitating more than four miles of a large-diameter pipeline between Lake Murray and Sweetwater Reservoir. The 66-inch and 69-inch diameter pipe provides water to Helix Water District and the Sweetwater Authority.
The pipeline runs under Baltimore Drive and along Spring Street in La Mesa, and extends south into Spring Valley. The $28.6 million project is part of the Water Authority’s multi-decade program to rehabilitate 82 miles of pre-stressed concrete cylinder pipeline in its conveyance system.
Construction crews will conduct most of the work underground, inside the pipe. They will access the pipe by excavating and entering the pipeline through 17 access sites, or portals. Most construction activities will occur at these access portals, which will be spaced approximately 525 to 2,500 feet apart.
The Water Authority began communicating with stakeholders along the pipeline last December. If you’d like to know more about the project, the Water Authority will host two open houses in September for residents living near the project and provide information at local events:
