Zoning
R-ED
Residential Environmental Development District
The R-ED District is established to accommodate residential development at a density of 2 du's per net acre in areas with a high proportion of sensitive environmental and historic resources. Protection of environmental and historic resources is to be achieved by minimizing the amount of site disturbance and directing development to the most appropriate areas of a site, away from sensitive resources. To accomplish this, the regulations allow site planning flexibility and require that development proposals be evaluated in terms of their effectiveness in minimizing alteration of existing topography, vegetation and the landscape setting for historic structures.
