AI Contract Overview

The project involves the 10-year operation and maintenance of Dry Docks 1, 2, and 3 at Mare Island in Vallejo, California, to sustain ship repair capabilities. Each year, up to 104 dry dock evolutions will be conducted, involving the controlled filling and draining of the docks with water from Mare Island Strait, opening and closing caissons, and enabling vessel entry and exit. Concurrently, mechanical dredging using a clamshell dredger will remove up to 140,000 cubic yards of sediment annually from a 12-acre area in the strait. All operations include mandatory fish rescue and relocation activities as outlined in the revised Fish Rescue and Relocation Plan prepared by WRA, Inc., with updates through August 25, 2025. The project is authorized under an Incidental Take Permit issued by the California Department of Fish and Wildlife, which allows for incidental take of several protected aquatic species, including threatened longfin smelt and Spring-run Chinook salmon, endangered Delta smelt and Winter-run Chinook salmon, and candidate species white sturgeon. The permit was amended to include white sturgeon as a covered species, with take anticipated solely through pursuit, capture, and relocation during fish rescue efforts, not through mortality. The City of Vallejo serves as the lead agency, with oversight coordinated through environmental compliance with the California Endangered Species Act and the California Environmental Quality Act. All work occurs at the Mare Island Dry Docks site, including Dry Docks 1–3, adjacent berths, and the surrounding waters of the Mare Island Strait, with environmental monitoring and reporting required to fulfill permit conditions. No contract pricing, payment details, evaluation factors, or standard FAR clauses are included in the available documentation, indicating this is an environmental and operational planning notice rather than a full procurement package.

Full Description

The Project includes ongoing operation of Dry Docks 1, 2, and 3 and maintenance dredging over a 10-year period. The purpose of the Project is to continue to provide a ship repair facility at the Mare Island Dry Docks. Up to 104 evolutions (i.e., filling the dry dock with water from Mare Island Strait, opening the caisson, allowing a ship to enter or exit the dock, and then draining the dock and performing fish rescue and relocation activities) will be performed in Dry Docks 1, 2, and 3, collectively, each year. Additionally, up to 140,000 cubic yards of sediment will be removed from an approximately 12.00-acre area in the Mare Island Strait each year via a mechanical (i.e., clamshell) dredger. Amendment No. 2 adds white sturgeon (Acipenser transmontanus) as a Covered Species to the ITP. Amendment No. 2 will not result in additional take of the originally Covered Species. Take of white sturgeon in the form of mortality is not anticipated to occur as a result of the Project, rather, take is anticipated in the form of pursue, catch, and capture from fish rescue and relocation activities pursuant to the Mare Island Dry Dock Fish Rescue and Relocation Plan, Revised, Mare Island, Solano County, prepared by WRA, Inc., revised May 20, 2014, April 10, 2020, and August 25, 2025 The Project is expected to result in incidental take of up to 7,462 individuals of longfin smelt (Spirinchus thaleichthys), and a smaller number of Delta smelt (Hypomesus transpacificus), Winter-run Chinook salmon (Oncorhynchus tshawytscha), Spring-run Chinook salmon (Oncorhynchus tshawytscha), and white sturgeon. Longfin smelt and Spring-run Chinook salmon are designated as threatened species under CESA. Delta smelt and Winter-run Chinook salmon are designated as an endangered species under CESA. White sturgeon is a candidate species under CESA. The ITP referenced above as issued by CDFW authorizes incidental take of listed or candidate species under CESA that may occur as a result of Project implementation.
