About this file

Written by GovTribe AI · Jul 3, 2025

This document is a detailed engineering and dredging plan for the FY25 Petaluma River Channel Maintenance Dredging Project in Marin and Sonoma County, California, prepared by the U.S. Army Corps of Engineers San Francisco District. The project involves maintenance dredging of the Petaluma River Channel to a project depth of -8 feet Mean Lower Low Water (MLLW), with an additional 1-foot of paid overdepth allowance, spanning approximately 1,067.85 linear stations across nine distinct reaches.

The dredging work includes different disposal requirements based on the channel reach: materials from Reaches 1 through 6 must be transported to a contractor-furnished upland beneficial reuse site, while materials from Reaches 7 through 9 are to be disposed of at the aquatic site SF-10. The project documents provide comprehensive geospatial data, including channel alignment control points, bathymetric survey information, and detailed dredging plans with depth measurements for each station. The solicitation number is W912P725BA005, with the project targeting maintenance of navigation channel depths to facilitate maritime transportation in the Petaluma River area.
