DR 3.5

Density Residential, 3.5 dwelling units per acre

The D.R. zoning classifications are established, pursuant to the legislative findings set forth above, in order to: Foster a greater variety in housing types within future residential developments; Allow more feasible preservation of natural features and induce the reservation of ample and more suitably designed open spaces and parks, in order to better satisfy the needs of residents without economic disadvantage to developers; Allow greater flexibility in subdivision-development planning and provide for the inducement of more creative as well as more economic approaches to residential development, with the goal of desirable and distinctive identity and character of individual residential locales; Provide the means to satisfy differing housing-market requirements without rezoning, and thus without disruptive changes in density potential; Provide for the application of residential zoning classifications in a manner more nearly in accord with comprehensive plans and comprehensive-planning goals and Provide greater certainty about dwelling types and densities within existing communities with the goal of conserving and maintaining these areas.
