Tomales Bay Vessel Management Plan

Solicitation # A4810

The Tomales Bay Vessel Management Plan facilitates coordinated vessel management in Tomales Bay, California, to enhance water quality, safeguard wildlife and habitats, protect public health, and preserve recreational access, all in alignment with mandates from the Gulf of Farallones National Marine Sanctuary and the California State Lands Commission. The primary action under this plan is the issuance of a 10-year General Lease for Recreational Use, authorizing the installation and operation of a single mooring buoy at designated sites adjacent to Teachers Beach near Inverness or Nicks Cove in Marin County. Environmental compliance is governed by the California Environmental Quality Act, with a Negative Declaration adopted on April 26, 2013, confirming that the project will not result in significant environmental impacts, and the lease was officially approved on August 21, 2025. The California State Lands Commission serves as the lead agency, overseeing all permitting, inspection, and acceptance processes, with no federal acquisition regulations or standard contract clauses applied, as this is a state-level administrative and environmental action. There is no disclosed contract value, pricing, or cost details, indicating this may be a low- or no-monetary-value lease arrangement with nominal consideration. No federal contracting mechanisms such as FAR clauses, payment systems, invoicing methods, accounting codes, or contracting officer designations are involved. Similarly, there are no solicitation numbers, evaluation factors, offeror certifications, size status requirements, or submission instructions typical of federal procurements. The sole deliverable is the lease authorization itself, with performance occurring entirely within the sovereign waters of Tomales Bay under state jurisdiction. Contact for information is provided through Robin Tuohy, Environmental Scientist at the Commission, and all documentation is publicly accessible via the CEQA.net portal, emphasizing procedural transparency rather than competitive bidding or commercial contracting norms.
