There's a few more projects popping up in this area. There's a housing development planned for Stassney Lane between South First and Congress on the south side. They've had the property fenced off for a while with a "coming soon" sign up. During one of the last storms we had, that entire construction fence blew over - several hundred feet of it. There's also another project planned for the property at South First and Stassney. It's another housing development that's going in that field behind the Walgreens and that church that faces South First. They're planning a new street back in there that they'll line with houses.
They have them listed on the city's FTP site. I forget which number, but they're in there.
