Hamilton Wetlands and Bel Marin Keys Unit V Restoration

construction vehicles at BMK

Update August 2021
We are near completion of Phase 1 of the restoration project. More information on the restoration of the seasonal wetlands and volunteer opportunities can be found on the Novato Baylands Stewards website.
Update December 2020:

Before demobilizing from the site for the rainy season, we anticipate that the North end of the project (closest to BMK) including the tie into the Novato Creek levee, the alkali meadow, seasonal wetlands, and the pump station will all be complete. The only Phase 1 tasks left to be completed are the work associated with tie into the NSD Outfall, and the N1 levee tie in at the very South end of the project.

The restoration of Bel Marin Keys Unit V resumed the week of April 1, 2020 with the mobilization of equipment to the site. The project has been deemed an essential public works project, so is proceeding on schedule. The project team is practicing physical distancing and taking additional precautions to protect themselves, each other and the community.


In response to BMKCSD dust control concerns, the project team is evaluating the options available.


As before, large vehicles will be working on site and visibility can be limited so please stay on the upper levee road and keep pets on leashes.
Also, please be aware that the site includes protected species habitat and that a buffer zone will be established as a protection. Please stay on the designated roads and avoid sightseeing – these animals, and their habitat, are extremely sensitive and legally protected.


For questions related to the construction of the project, please contact Construction Manager Russell Barnes: 707-815-1707; rbarnes@wilshireconsultingllc.com .

On August 22, 2019, the Board of the State Coastal Conservancy approved $20 million in funding for the first phase of the restoration of BMKV.  A solicitation for bids for construction of the Bel Marin Keys Unit V Phase 1 project component of the Hamilton Wetlands Restoration Project was posted at Cal eProcure. The construction manager is Russ Barnes of Wilshire Consulting: rbarnes@wilshireconsultingllc.com.

The restoration of Bel Marin Keys Unit V (BMKV) and the adjacent North Antenna Field (NAF) is expected to commence this Fall (2019). The restoration of these properties will create new wetlands habitat for wildlife, flood protection for the community of Bel Marin Keys and complete the Hamilton Wetlands Restoration Project.  This component of the Hamilton Wetland Restoration Project seeks to create a mosaic of tidal, seasonal, and transitional habitat by constructing flood control features, placing dredged material to elevate the diked, subsided baylands, and reintroducing tidal waters to the site.
