Sonoma County leaders are poised to move forward Tuesday with a yearslong effort to redevelop their aging and sprawling north Santa Rosa government campus, a measure that could make room for at least 1,400 housing units.
The Board of Supervisors will consider directing county staff members to gauge developers’ interest in building a consolidated 500,000-square-foot administrative center to accommodate county offices that currently are spread among numerous low-rise buildings, most of which are 50 to 60 years old.
The buildings have an ever-growing maintenance backlog, currently pegged at $258 million. County officials think they’re better off building a denser office complex, either on the same site or elsewhere, and freeing up space for desperately needed new homes.
“It’s like when you have a car that you’re spending more money on maintenance than it’s worth,” said Supervisor James Gore, the board chairman. “And you say, what if I sold it?”
Four general locations for the new government center are being floated by county staff: the existing site centered in the area around Administration Drive, downtown Santa Rosa, the county airport business park or another location proposed by a developer.
If the county moves its administrative offices downtown, it could opt to share a site with the Santa Rosa city government, which is mulling its own move out of the City Hall complex on Santa Rosa Avenue.
Santa Rosa Mayor Chris Coursey said the city is interested in getting new housing built on the site, making a combined government center an attractive option for city officials. But Coursey warned the idea at the moment is “one of those moonshot type of things.”
“Under the proper circumstances, it would allow housing to be created — a lot of housing — at the county center and on the City Hall property where we sit now,” Coursey said.
“I think it is a great idea,” he said. “It would take a lot of work to make it happen. We’re in the very preliminary stages of getting to that point.”
The county campus totals about 47 acres, but not all of it is slated for redevelopment: Justice-related buildings, including the Sheriff’s Office and the county jail, would remain. The Sonoma County Superior Court already is planning to move into a new courthouse, but the existing Hall of Justice where the court currently is located could be replaced or refurbished as part of the broader plans for the administrative campus, said Caroline Judy, the county’s general services department director.
The county thinks housing could be built on 60 percent of the campus, allowing for an estimated 1,410 units under the neighborhood’s current zoning rules and as many as 3,892 units if higher density is allowed, she said.
It’ll likely be several years before any of those units comes to the market, however. If supervisors agree to move forward this week, county staff members will release a questionnaire to gauge developers’ interest this summer, then launch a formal request for development proposals no sooner than this winter, Judy said.
Still, the potential housing project could give a major boost to supervisors’ ambitious goal of getting tens of thousands of housing units built in the coming years.
