A natural habitat for Delta waterfowl and wildlife, and more recently grazing cattle, Jersey Island in East Contra Costa County has remained largely undeveloped for more than a hundred years. Plans are percolating, though, that could turn it into a vacation getaway with a wave pool, sandy beaches, a wildlife refuge — and more — close to home.

That’s what one entrepreneur/developer, Montezuma Water LLC, has in mind with a preliminary concept it has presented to the island’s owner, Ironhouse Sanitary District, which has been looking for ways to reduce its responsibilities for the surrounding levees and shed some of its expenses for an island it no longer needs.
