R-3A and R-5A: Sensitive areas to be developed only at very low density, because of lack of central water and sewer, and because of their scenic values, slopes and/or wetlands and floodplain complexes.

R-80: Sensitive areas to be developed only at low density, without central sewers, because of their scenic values, slopes or wetlands and floodplain complexes. Rigorous scenic buffers should be required along the Hudson River sites.

R-40/80: Areas outside of the currently proposed regional municipal sewer service area, which should be developed at R-80 if that area is not extended to them, but which should be permitted a density of R-40 if a link is made to the regional municipal (or other system consistent with the Town sewer and water plan). These areas are not as environmentally sensitive as the R-80 and in western Wappinger tend to be surrounded by existing higher densities.

R-40: These zones cover either existing developed areas outside the proposed regional sewer system service area, areas within the proposed regional sewer system service area or small undeveloped tracts in transitional areas adjacent to higher density developments (such as Chelsea). If within the proposed sewer service area, these sites should only be developed if tie-ins to the regional system are provided.

R-20/40: Areas within the sewer service area that have either already been developed at this density or, because of their proximity to Route 9, the Village of Wappingers Falls or other higher density areas, are appropriate sites for R-20 densities as long as they connect to the regional sewer system.

R-20: Areas that have already been fully developed at this overall density.

R-15: Existing R-15 areas that have been developed at this overall density.

R-10: Existing R-10 areas that have been developed at this overall density.

CC - Conservation Commercial. Intent: To permit commercial use of strategically located sites that have sensitive environmental features (wetlands, floodplains, steep slopes along stream corridors) at densities and under performance standards that will preserve those resources. Filling or building construction should not be permitted in wetlands areas, one-hundred-year floodplains or stream corridors and ravines in this zone.

COP - Conservation Office Park. Intent: To permit office/research use of strategically located sites that have sensitive environmental features (wetlands, floodplains, steep slopes along stream corridors) at densities and under performance standards that will preserve those resources; to encourage development of such areas in campus-style facilities, with access to major highway routes; to provide for more diverse employment opportunities in the Town. Filling or building construction should not be permitted in wetlands areas, one-hundred-year floodplains or stream corridors and ravines in this zone.

HM - Hamlet Mixed Use. Intent: To preserve the historical character, concentrated development pattern and mixture of uses in existing commercial hamlets, particularly Hughsonville and Swartoutville, by encouraging restoration, reuse and visual improvement of existing structures.

HD - Highway Design District. Intent: The uses are designed to discourage automotive uses; stand-alone, franchise, fast food establishments and certain other uses, and to encourage the development of office uses, scientific research, engineering or design laboratories, and other uses that can help diversify the Town's economic base.
