Here are the proposed subdivision maps for the Emerson site, showing the proposed “OU-1” (0.9 acres off South Cayuga Street, contains two underground storage tanks, and a treatment building) and “OU-2” (95 acres, the rest of the site). The split looks like a deal-maker to sell the site to the potential developer in order to relinquish an overburden of remedial work on the entire parcel. Emerson’s operations here closed for good back in 2009, so it’s nice to see some forward motion on a site this massive.
