About Mare Island

Mare Island was the nation’s first naval shipyard on the West Coast, established in 1854 and ultimately closed in 1996. It is 5,000 acres and includes commercial, residential and open space uses. Included in Lennar Mare Island's portion of the Mare Island Reuse Plan are 1,400 homes, roughly 7 million square feet of commercial and industrial space, plus many recreational amenities.

The new mixed-use, master-planned community is being developed through a unique public/private partnership between the City of Vallejo and Lennar Mare Island, LLC.
