One of the chief goals in recent months for Gainesville Mayor Danny Dunagan and other city officials has been to acquire the old county jail on Main Street so it eventually can be torn down.Though the city has reached an agreement to secure ownership of the building, Dunagan, in his early 60s, admits he may be dead and buried before the jail is leveled.For years, Gainesville officials have made it clear they want the jail, currently used by a private company to detain illegal immigrants, gone.Finally, the city shelled out $7.2 million to buy the jail from Hall County in order to control the destiny of what many consider an eyesore and a potential roadblock to midtown redevelopment. Eventually, the city hopes to sell the property to developers.But don’t expect a wrecking ball to plow through the brick walls of the jail anytime soon.In its agreement with the previous jail owner, Hall County and current tenant, Correction Corporation of America, the city agreed to potentially let the jail stand until 2026.The center will continue to house detainees of the U.S. Immigrations and Customs Enforcement under CCA’s operation. The Hall County Sheriff’s Office will continue to occupy an office there for at least five years.The three main parties to the arrangement — Gainesville, Hall County and CCA — are applauding the deal as beneficial to all.
