The owner of record is Edgewater Owner II LLC. The project's plan drawings are on file — worth a look for anyone underwriting the surrounding block.

For now it stands out on its block — there's little other major development within a half-mile, which makes the surrounding under-built parcels worth a closer look as this density arrives.

We'll update this page as the project progresses — leasing, retail tenants, renderings, and construction milestones as they surface. The relevant question for investors and agents: what are the surrounding parcels worth to a builder now that this is coming?
