This report shows a number of great, livable neighborhoods in communities like Lexington, Cohasset, Great Barrington, etc. where under the municipality’s “official” zoning, the neighborhoods would be illegal and could not exist. These are neighborhoods that residents enjoy for a variety of special characteristics that would have been blocked in typical zoning. Zoning can result in a too homogeneous community, excluding the serendipities of co-location in a land use development process evolving over a great many years. Can we anticipate these synergies and include them to enrichen our town’s neighborhoods?
