Allen Buck is optimistic about the future. The 33-year-old Gainesville resident stopped Wednesday to contemplate an empty city-owned parking lot fronting Jesse Jewell Parkway between West Academy and Maple streets - site of a $25 million multi-story complex that will bring approximately 150 market-rate apartments, restaurant and retail space in late 2019. The project is the most expensive of three mixed-use developments totaling $5 million announced Tuesday night by city officials.
