2007 Community Survey
As part of the 2007 POCD the Town conducted a Community Survey
April 2007 Community Survey Completed
1) 3rd most important issue after taxes and education is “too many large houses”
2) “Limit house size”, identified as the #1 quality of life issue
2007 Plan of Conservation and Development
“ It is a central goal of this Plan and of prior plans to maintain the low density single family residential character of Westport’s neighborhoods. The overall character and ambience of existing neighborhoods is responsible for the recognized quality of life in Westport.”
“In addition, the zoning regulations in place in Westport allowed such development to occur. When the regulations were adopted more than a half century ago, nobody anticipated that future homeowners would attempt to maximize every dimensional standard in what was intended to be a flexible “building envelope”.
“Westport’s zoning regulations need to be amended to ensure that housing units being built are in scale and proportion with the lot size and the neighborhood”
2007 Plan of Conservation and Development
•Adopt a building coverage limitation for all zones.
•Consider adjusting what elements are considered in building
coverage and total coverage.
“Manage Housing “Rebuilds”
“Evaluate the Zoning Regulations for ways to reduce land coverage and building size to conserve energy”
“Most threats to water quality in Westport come from storm water runoff which has picked up sediment, automobile emissions and debris, pesticides, fertilizers, and other pollutants “
