The Danbury Zoning Commission has taken up a proposal to make changes to 4 properties on Federal Road near the Brookfield border.  An application is looking for a zone change from industrial to commercial.  Zoning Commission Chair Ted Haddad says there were unregistered vehicles, garbage and other bulky debris scattered throughout the 1-point-6 acre parcel of land.  One landlord responded during a hearing that he plans to clean up the site.  The properties are located at 21 to 39 Federal Road.  Planning Director Sharon Calitro supports the proposal to convert one of the last industrial parcels on northern Federal Road into commercial land.  In a report to the Planning and Zoning Commissions she said that over time the uses along the corridor have changed to a more retail nature.  One reason she supports the change is that it could provide more attractive and safer parking layouts.  The public hearing was closed on Wednesday night, but the commission did not issue a ruling.
