Frequently Asked Questions

What is Delta Coves? 
Delta Coves is a new-home community that caters to water-loving families with exceptional facilities, fun activities, and a premier location on a 145-acre lagoon in the California Delta. Developed by DMB Development, LLC and managed and operated by Cohere, Inc., Delta Coves features 461 waterfront residences, each with a private dock for launching boating adventures in the Delta’s 1,000-plus miles of waterways. Celebrating the region’s laid-back lifestyle, Delta Coves is also home to the Island Camp, a 15,000-square-foot communal hub designed by architectural firm Hart Howerton and complete with a clubhouse, fitness center, swimming pool, event lawns, mini-beach, and picnic pavilion.

Where is Delta Coves located?
Delta Coves is poised along the canals of the California Delta on Bethel Island in Northern California’s Contra Costa County. The largest freshwater estuary on the West Coast of the Americas, the Delta is an intricate network of rivers, canals, and sloughs that connects the Sierra Nevada range with the Pacific Ocean. Famed for its agriculture, the region is also a critical habitat for a range of wildlife and a world-renowned destination for waterskiing, fishing, and other watersports.
Delta Coves’ prime location on a man-made lagoon sits at the gateway to the Delta’s 1,000-plus miles of waterways and 740,000 acres of natural preserves. The canal-front setting and the region’s warm, Mediterranean-style climate set the stage for an active lifestyle that revolves around the water—and Delta Coves is just 10 minutes from the Delta’s fast water by boat.
By car, the community is about 55 miles east of San Francisco, 70 miles northeast of Silicon Valley, 60 miles southeast of Napa Valley, 50 miles east of Oakland, and 30 miles east of Walnut Creek. Additionally, BART’s new Antioch Station, which is only eight miles away, offers easy access to the Bay Area.

What makes delta coves unique?
Delta Coves is unlike anything else on the Delta—and the Delta is unlike anything else on Earth. The first community of its kind in the region, Delta Coves will also be the last, as there is no other development being permitted in the area.
Delta Coves is distinguished by the quality of its residences and amenities—including the Island Camp Club and the swimmable lagoon—as well as its unparalleled location and unique, water-centric community programming. It’s the only new community with direct access to the Delta’s fast water, so while most developments require a long commute to reach the skiing sloughs, Delta Coves offers the equivalent of a backstage pass to the action.
Once you arrive at Delta Coves, you never need get in your car again to enjoy endless water amenities. Life is on your boat and in our coves. From your dock, you can explore the great Delta and even head to Sacramento, San Francisco, or any destination in the Pacific Ocean.
