Twenty-one years after Plattsburgh Air Force Base in New York’s Champlain Valley region was shuttered, the base’s local redevelopment authority is close to putting itself out of business.

If three pending sales go as scheduled, Plattsburgh Airbase Redevelopment Corp. (PARC) will have only three other properties left to market, Lee Mitchell, PARC’s chief financial officer, said last week at the corporation’s annual meeting. The three parcels total 16.3 acres and are valued at $933,000.

Over the last two decades, PARC has taken advantage of $115 million in state and federal investment to refashion the site into an industrial park specializing in aerospace, rail transportation, manufacturing and other fields. PARC has negotiated 170 property sales or transfers and 200 leases to redevelop 1,717 acres, reported the Press-Republican.

The corporation’s sale of a parcel to Clinton County in the previous fiscal year marked the end of its landlord responsibilities, according to Mitchell.

“I think we can be proud of the work that has happened, and I think that shows we have done our job as well as possible,” she said. “Again, we’re almost there.”
