Marina & River Dredging

Project Description

The U.S. Army Corps of Engineering (USACE) is currently developing permitting and construction documents for the dredging of the Federal Channel within the Petaluma River. The City through this project will ensure that the Shollenberger dredge disposal site will be ready to receive dredge spoils from the Upper River Channel. Dredging by the USACE is expected to take place during the summer of 2020. In addition, the City of Petaluma plans to perform its own maintenance dredging of the Petaluma Marina. By doing so the City hopes to increase the marina traffic as well as provide increased access for both commercial and recreational maritime vessels.

Traffic Impact

When dredging occurs in the Turning Basin, the D Street Bridge will be opened multiple times a day, thereby, impacting traffic along D Street. During the project, the areas undergoing dredging will not be accessible to the public and marine traffic will likely be impacted.

Project Status/Timeline

The City of Petaluma and the USACE completed the required sediment sampling and are currently in the process of applying for a 10-year maintenance dredging permit for the Marina and Turning Basin through DMMO. The City will also be applying for the Measure AA Grant to provide additional funding for the dredging. In addition, the City has been pursuing additional funding and project partners to make a push for beneficial reuse of the dredge materials and to develop a long term, sustainable plan to have the river and marina regularly dredged. Beneficial reuse could include the use of the dredge material to enhance the resiliency of the Petaluma Marsh and help protect additional vulnerable locations along the Petaluma River.
