A gleaming, four-story apartment complex stands atop a small hill that overlooks a bustling arts-themed district, where specialty shops, hip food joints and art galleries are rapidly replacing decaying storefronts. To see what the Rivers Edge project might bring to the Crossroads of Delmarva in a few years, start here, says Andrew Hanson, vice president of Osprey Property Co. "I think it's going to serve a lot of artists who need quality housing and bring a lot of enrichment" to the downtown area, Hanson said of his development plans, which won the backing last week of a once-opposed City Council majority.
