When it came time to select between four proposals for the development of prime downtown Gainesville property owned by the city, the decision was left up to a panel made up of mostly local government insiders. Gainesville Mayor Danny Dunagan headed the panel that selected Atlanta-based Knight Commercial Real Estate and hometown company Carroll Daniel Construction to develop three mixed-use projects on the city’s property. The projects with a combined investment of $53 million were unveiled last week, and will include housing, office space, restaurants and retail.
