The purpose of this Residential Open Space Conservation District U-4 is to encourage environmentally sensitive residential development and other harmonious conditional uses enumerated herein in those portions of the community impacted by severe development constraints, including, but not limited to, severe slopes, unstable soils, wetlands, natural drainage courses, sensitive environments and floodplains. Development under the provisions of these regulations contributes to improved air quality, improved water quality, and enhanced biological diversity compared to development under traditional practices by enabling less soil exposure, less erosion, less sedimentation of natural drainage courses, and less disturbance of vegetation and sensitive environmental features. In doing so, these regulations contribute to the health, safety, and welfare of existing and future residents. (Ord. 2013-05. Passed 6-12-13.)
