Open space required. All residential development subject to this article shall require the preservation in perpetuity of open space in conjunction with the development project.
A. Open space in larger tracts will be preferred, as will open space contiguous with other already preserved open space. Except land reserved as public parkland or playgrounds in the PD and R10 Zones, no parcel smaller than two acres that is not contiguous with such other open space may be counted as part of the required open space in projects larger than 10 acres.
B. The open space should protect valuable natural and cultural elements, including water bodies, streams, wetland buffers, unfragmented forest, wildlife habitat, open fields, scenic views, trails, stone walls, archeological sites, and avoid development in hazardous areas such as floodplains and on steep slopes. In areas where public sewage disposal is not available, consideration shall be given to the suitability of soils for on-site disposal systems both within and outside the protected open space. Particular consideration for protection will be given to land that expands land that is already protected or which is recommended for protection under the Town Master Plan or Open Space and Recreation Plan, or will tend to expand or complete wildlife or recreational corridors between such parcels.
C. R80 and C2 Zones. Of that portion of a residential development project that is located in the R80 and C2 Zones, not less than 50% of the area (without any deduction for streams, ponds, wetlands, stream buffers, wetland buffers, vernal pools and areas with a slope greater than 1:4) shall be preserved as dedicated open space. If the total wetlands-related areas (streams, ponds, wetlands as defined by law, and vernal pools) within the dedicated open space will exceed 33% of the total area of the development site, only that 33% may be counted in making up the required 50%.
D. R40 Zone. Of that portion of a residential development project that is located in the R40 Zone, not less than 33% of the area (without any deduction for streams, ponds, wetlands, stream buffers, wetland buffers, vernal pools and areas with a slope greater than 1:4) shall be preserved as dedicated open space. If the total wetlands-related areas (streams, ponds, wetlands as defined by law, and vernal pools) within the dedicated open space will exceed 25% of the total area of the development site, only that 25% may be counted in making up the required 33%.
E. R10 and PD Zones. Of that portion of a residential development project that is located in the R10 and PD Zones, not less than 25% of the area (without any deduction for streams, ponds, wetlands, stream buffers, wetland buffers, vernal pools and areas with a slope greater than 1:4) shall be preserved as dedicated open space. If the total wetlands-related areas (streams, ponds, wetlands as defined by law, and vernal pools) within the dedicated open space will exceed 15% of the total area of the development site, only that 15% may be counted in making up the required 25%.
F. C1 Highway Commercial and I Industrial Zone. Residential development is not allowed in these zones.
