The purpose of the PRD Zone is to allow single-family, two-family and multi-family residences on a minimum 15 acre site with a minimum 300 foot frontage on the Post Road. The PRD provisions are intended to encourage moderate density development (less than the Residence B Zone density) for primarily smaller sized residential dwellings on vacant or underutilized parcels in areas along the Post Road and served by centralized sewerage facilities. It is in the public interest to preserve the residential qualities of Westport, to provide a desirable alternative to presently permitted commercial uses in specific locations, to reduce the potential traffic and drainage impacts on Town facilities, and to provide a broader choice of housing types in Westport. The PRD can help to achieve these objectives.(813, 03/27/2023)
