Mare Island Conceptual Plan

The Mare Island Company is redeveloping the historic Mare Island naval shipyards into a new mixed-use waterfront district. The island lies between the Napa River and San Pablo Bay, 23 miles northeast of San Francisco.

For nearly a century-and-a-half—from 1854 to 1993—Mare Island hosted an important U.S. naval base. It has a rich industrial shipbuilding history.

Mare Island currently has 3.6 million square feet of leased commercial, industrial, manufacturing and office space as well as ferry service to major Bay Area cities and Wine Country. It is also home to historic landmarks, nature preserves, entertainment venues and 300 residences.

The master plan covers nearly 1,000 acres of developable land, including 3.5 miles of waterfront land accessible to pedestrians, in a designated opportunity zone. The plan blends heritage conservation strategies for the historic working waterfront with natural habitat preservation while envisioning contemporary new uses.

HOK is leading the ongoing community outreach and master planning process as well as creating architectural design guidelines and sustainability strategies.

Four themes underpin the plan:

• The relationship of nature to the built environment
• Community and people
• Economic development
• Mobility, transportation and connectivity

In addition to the Mare Island Company, HOK’s team is collaborating with the City of Vallejo.
