The Napa County Board of Supervisors has voted to study the environmental impacts of three possible ways to renovate the county’s Health and Human Services campus on Old Sonoma Road.
The first would remove the historic buildings that abuts Old Sonoma Road, keep construction confined to the current campus, but would need a parking garage to be built.
A second option retains the historic buildings, and would require the county to purchase 3.3 acres from an adjacent school, allowing construction to be spaced out without the parking garage.
The third would explore the possibility of moving the campus out of the Old Sonoma Road location and into a new site.
The board voted Tuesday to allow the county Planning Department and its consultants to begin the studies, called an environmental impact report. The report is due for a public hearing by September.
The project, which a preliminary estimate said will cost $50 million, is needed to give the Health and Human Services agency additional and more modern space. The agency currently occupies buildings that range from 55 to 70 years old.
The first phase of construction is expected to begin in 2014 and will cost $27 million. The project isn’t expected to be complete for at least 20 years.
The first alternative, which would confine construction to the current campus, would be the most cost-efficient, as it would provide the space Health and Human Services has identified it will need in 2015 within the $27 million budget.
The second alternative would be cheaper over the long term, but the phase one budget wouldn’t provide enough money to give the agency the space it desires in 2015. The county would need to pay an estimated $2.5 million extra to accomplish that.
For the third option, county Planning Director Hillary Gitelman told the board staff will have to look at available sites for the campus relocation, and then determine cost estimates and how they could fit the agency’s need.
