Chattanooga is considering the adoption of something called "view zoning." The idea basically is to zone certain areas adjacent to scenic or historic sites and then restrict construction in those zones. The Chattanooga proposal exempts one in two family residential structures, and does not completely preclude the possibility of other types of development. Rather, it requires that a special permit be obtained from an administrative body permitting the construction after review.
The regional planning commission recommended approval. The local legislative body will vote on the proposal sometime in December.
