A development site in Lincoln Park has traded for double what it fetched two years ago. Jeff Shanahan, a local income-restricted housing developer, sold his 1530 W. 13th Ave. property earlier this month for $12.5 million to Atel Street LLC, according to public records. He had planned to build nearly 200 apartments on the 1.4-acre site. The deal works out to $205 a square foot for the land.
