Q: What is the status of the Trinity Avenue Farm? Has a finalist been chosen, and will the project proceed?

—Bert Vogelbacher, Marietta

A: The final cost estimates are expected by early June and a winner for the design contest likely will be announced by the end of next month, Aaron Bastian, the communications and project manager for Atlanta's Office of Sustainability, told Q&A on the News in an email. Work on the urban farm project will begin immediately after the winning design is announced. The competition was "developed to inspire creativity and innovation" as the city "works to establish an effective … model for urban agriculture within Atlanta communities — showcasing how fresh food can be grown locally and sustainably," according to the project's website (www.trinityavenuefarm.org). The 0.8-acre lot for the Trinity Avenue Farm is across the street from City Hall, on the corner of Trinity and Central Avenues, which was the site for the traffic court building from 1956-2007. A prize of $25,000, provided by Wal-Mart, will go to the winning team.

The gun's serial number was erased, and agents partly raised the digits, according to The Washington Post.
