The Contra Costa County Board of Supervisors has unanimously denied an appeal of the county planning commission’s approval of a 144-unit residential subdivision, on 78.2 acres just outside Martinez, east of Interstate 680 in the Vine Hill area.

Seeno/Discovery Homes’ Bayview Estates Residential Project will have detached single-family homes and associated roads on 31.8 acres of the site. It will also include approximately 42 acres of open space, marshes, and undeveloped land, including 20.1 acres of the upper hill area. There will also be a 4.5-acre private neighborhood park.

Central Avenue will be the subdivision’s main access road, though the neighborhood will also be accessible via Palms Drive.

Residents of private Palms Drive spoke against the project, saying the lack of roads in and out of the project will make it problematic in the case of a fire, and the builder should not be allowed to cut down 30 protected trees. Discovery Homes obtained tree removal permits and will replant 30 trees.
