Construction Projects

Current CVSan Project

Center Street Project
In 2013 Castro Valley Sanitary District (CVSan) acquired a 73,000-square foot property located at the intersection of Castro Valley Boulevard and Center Street for $1,500,000. This property was formerly owned by the California Department of Transportation and was surplused by the State of California.

CVSan plans to develop this site into a 19,795-square foot, two-story building that would provide office space and other facilities such as equipment storage, conference rooms, amenities for employees (i.e.: kitchen, break room, shower, and lockers), and a public counter for the CVSan Engineering Department. This estimated $8 million project (2018 cost estimate) will include LEED-certified architecture and Bay-Friendly landscaping.

On October 1, 2019, CVSan’s Board of Directors awarded the contract for professional architectural services to Dahlin Group. Dahlin Group was one of three architectural firms that interviewed in June 2019.

CVSan anticipates the project will be ready for construction bid in Spring 2021.
