Longstanding efforts to improve public safety radio communications in northwestern New Canaan are poised to take a major step forward, as the owners of an Oenoke Ridge Road property have agreed to seek permission for an inconspicuous antenna to be placed on an existing barn around the back of their house, officials say. The antenna that would be placed on the four-acre upper Oenoke Ridge Road property would be just 20 feet high and three inches in diameter, officials say—used strictly for public safety communications (as opposed to, say, the type of “cell tower” that has been proposed for Soundview Lane and has drawn concern from some neighbors). The Board of Selectmen at its regular meeting April 10 voted unanimously to approve a $1,500 contract for a “building location survey” on the property. The work, to be done by New Canaan-based RKW Land Surveying, is part of an early-stage effort to determine for certain whether the location is viable. Additional engineering work must be done prior to applying to the Planning & Zoning Commission for a special permit.
