Section 304 - Basic Maximum Number of Dwelling Units
   A.   Yield Formula - The basic maximum number of dwelling units to be allowed in a proposed CSD project, regardless of the type of development proposed (i.e. single-family, two-family, or multi-family), shall be determined using the formulas below. Including only developable land area, and excluding land needed to account for roads and irregularities in parcel shape, the formulas determine the basic maximum number of dwelling units in a CSD, depending on the zoning district designation of the subject property:
 
Zoning District
R-10
Basic Maximum Number of Dwelling Units = Developable Land Area ÷ 9,000 sq.ft.
R-20
Basic Maximum Number of Dwelling Units = Developable Land Area ÷ 24,000 sq.ft.
R-30
Basic Maximum Number of Dwelling Units = Developable Land Area ÷ 36,000 sq.ft.
R-40
Basic Maximum Number of Dwelling Units = Developable Land Area ÷ 48,000 sq.ft.
R-60
Basic Maximum Number of Dwelling Units = Developable Land Area ÷ 72,000 sq.ft.
 
   Results of the formula calculation shall be rounded down to the nearest whole number.
   B.   Upon completion of its review, the Planning Board shall determine the initial Basic Maximum Number of lots/dwelling units permitted in a development. This initial determination shall be made at the master plan stage of review for major subdivisions and major land development projects, and at the preliminary stage of review for minor subdivisions and minor land development projects. The applicant shall use this initial determination as the basis for submission of more detailed information during subsequent stages of review. Upon further investigation and upon receipt of more detailed soils and environmental information as may be provided in subsequent stages of review, the Planning Board may reduce the number of lots/dwelling units contained in the initial Basic Maximum Number. For all developments, the final Basic Maximum Number shall be established by the Planning Board at the final stage of review.
   C.   In developments that require alterations to be made to freshwater wetlands, the Board may establish an initial Basic Maximum Number contingent upon confirmation by the RI Department of Environmental Management that such alterations are permitted under the provisions of the Freshwater Wetlands Act.
