New Coloma Pump Station Will Increase Capacity and Reliability
Coloma Pump Station Project Summary
The project includes demolition of two existing underground pump stations that will be replaced with a new pump station at Bridgeway Blvd and Coloma St. It will feature underground electrical controls and the installation of an emergency standby generator. The new pump station will have increased capacity and backup systems to meet needs during severe storms when flow can increase 900% or more.

Landscaping for the Coloma Pump Station Replacement Project:
A final landscaping plan was approved by the Sausalito Planning Commission on October 21, 2020. This completes all permitting requirements for the project. The plan was developed with input from Sausalito Beautiful, Shades of Green (a local landscape architect) and the Whiskey Springs HOA Landscaping Committee. District staff has been working with the Landscaping Committee since April of 2015 on the development of a planting plan and station design that allows for the protection of the mature Blue Atlas Cedar trees. As a condition of approval from the Planning Commission, the Atlas Cedar trees must be warrantied for 5 years. In the event a tree dies as a direct result of construction, as certified by an arborist, the District and the City of Sausalito will be required to share the cost of planting a new tree in the largest size available.
Implementation of landscaping will be bid separately from the rest of the pump station project, and solicited to professional landscaping companies rather than general contractors, to ensure work is performed correctly at this high visibility entrance to the City of Sausalito.
