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.

CVSan released a Draft Initial Study and Mitigated Negative Declaration (IS-MND) for CVSan's O&E Building Project (project) for review and comment to all applicable agencies, organizations, and interested persons (reviewers). The Notice of Intent (NOI) to Adopt a Draft IS-MND complied with the California Environmental Quality Act (CEQA). The Draft IS-MND was circulated for a 30-day review period. The specific posted comment period was from March 11, 2020, to April 10, 2020, at 4:00 p.m

Document Availability: Copies of this IS-MND are available for public review at the CVSan office at 21040 Marshall Street in Castro Valley.

Center Street FAQs: 

1. How will Castro Valley Sanitary District (CVSan) pay for the new Operations and Engineering (O&E) building? Are rates going to be raised to pay for it?

I heard the current CVSan building on Marshall Street is only 23 years old, why does CVSan need a new building?

How much is it going to cost to buy the land from California Department of Transportation, they haven't used it in years but with the recent real estate boom can CVSan afford that as well as the construction costs?

Will CVSan still have its office located on Patio Drive?

Is it a good time to build a new building? What about the economic impact of COVID-19?

What are the benefits of the CVSan O&E Building Project?
