I had thought the plan was to construct housing on Mare Island last time I heard about this.
Oh, they jacked that up completely.
When the navy turned it over, they included a suggested reuse plan. And that was to sell the old Officer and Chief housing for civilian use, and the enlisted housing for a low cost housing project (mostly 3 bedroom duplexes). And the substandard housing (mostly 2 bedroom apartments) that was on Sacramento for another housing project.
Well, they sold all of that, other than the old enlisted housing. That sat abandoned for almost a decade until they finally just bulldozed it all. because of damage by the homeless And I have lost count of the number of companies that have come in and proposed turning that into a new subdivision. Each and every time it failed, and the land is still sitting unused. Meanwhile what is left of the base continues to rot away, and I even worked with a non-profit about two decades ago.
It was an operation that gave housing and training to homeless vets, and the old enlisted barracks off of G street (the causeway to downtown) would have been perfect. Several buildings of barracks and a chow hall. The organization had done that on multiple closed bases, from Long beach to Hawaii. But when they approached Vallejo, they said they had plans already and did not want to house homeless veterans. And the city was offered keeping the exchange complex open and the Navy would rent it from them and continue to operate it, but the city refused.
Well, the buildings were never reused, but the homeless kept destroying them for the copper until the city finally destroyed them about a decade ago. At the rate it is going, there will be almost nothing left on that island in another decade. And I used to work for a company that was on what was McClellan AFB in Sacramento. The exchange is still open, and almost every building is rented and the housing has a waiting list to get into it.
Even the exchange complex on Mare Island has been abandoned for almost 3 decades. I have talked to some of the public works guys that still work there, and they said the city has absolutely no interest in renting anything out. They seem to still have these dreams that it will become the "Silicon Valley of the North", and some high tech companies will want to buy it all up and move there.
I was part of a group that was trying to use Eminent Domain to try and get the Marine Barracks before it completely falls apart. We even had a few potential financial backers to help us turn it into a museum, but the extent of the damage after sitting for almost three decades scared them all off as most estimates were around $10 million to return it to a useful condition again. They have done almost no maintenance on that building since the base closed, and it is on the National Historic Register. The PW guy said other than once or twice a year pumping out the flooded basement they have done nothing to it in decades. And the old WWI Navy Brig is in almost the same state. As is about half of the old Naval Hospital. Half is being used as a college campus, the other half is simply rotting away (and that also dates to WWI and is on the historic register).
Back when we had the Federal shutdown a decade or so back, the city was even complaining that the shutdown was keeping the Naval Cemetery on base from being maintained. Even though the city was supposed to have taken over all maintenance there as part of the turnover, and did nothing once they got it. I want to say a group of volunteers finally took over the maintenance there, as it was horrible the condition it was in.
