The Danbury City Council has reauthorized negotiations about paying for two parcels of blighted land near the airport--either through a sale or an eminent domain payment.  89 Wooster Heights Road and 25 Miry Brook Road continues to be the subject of enforcement actions by the City, the state Department of Energy and Environmental Protection and others.  The properties are within the flight path of the airport and funds from the FAA may be available to purchase and improve the sites.  City officials say this would ensure aircraft safety, and that personnel and property is fully protected and maintained.  Danbury could also use open space money to acquire and restore the land.
