The Danbury Zoning Board of Appeals postponed a public hearing last night into an application for a 211-square foot, illuminated LED sign with changing content at the soon-to-be-opened Caraluzzi's.  The market is looking for two variances for the sign at their Mill Plain Road locations.  The sign would change no sooner than every 10 seconds, which is slower than the sign at City Hall, where some messages change every four or five seconds.  The sign would be larger than the digital Stew Leonard sign, the digital sign for ShopRite and the nearby Danbury Green on Mill Plain Road.  The next meeting of the Zoning Board of Appeals is April 28th.
