Zoning
RDD-5
Rural Development District
The Rural Development District is the portion of land in Lewis County not otherwise designated. While the Rural Development District has an overall density designation of one unit per five acres, the combinations of steep slopes, tight soils, flood plains, and unbuildable critical areas will provide a wide variety of rural residential densities, and will preserve the rural character of the county while providing reasonable opportunity for any low density development. The purpose of this chapter is to achieve a variety of lot sizes, protect rural character, and protect small rural business which have historically served the citizens of Lewis County.
