[Amended 5/12/2008 by Ord. No. 389]
A. Density Factors: for purposes of calculating density under the Cluster Option, the following density factors shall be applied:
1. Conservation Residential (CR) District: 1.00
2. Suburban Residential (SR) District: 2.25
B. Adjusted Tract Area Approach: Determination of the maximum number of permitted DWELLING UNITS on any given property under the Cluster Option shall be based upon the Adjusted Tract Area of the site. The Adjusted Tract Area equals the gross tract area minus the constrained land (described below) calculated in accordance with the worksheet included in Appendix C.
1. Constrained land equals the sum of the following:
(a) All land within the rights-of-way of existing public streets or highways, or within the rights-of-way for existing rights-of-way of utility lines;
(b) All land under existing private streets;
(c) Wetlands: multiply the acreage of designated wetlands by 1.0;
(d) Floodway: multiply the acreage within the floodway by 1.0;
(e) Floodplains: multiply the non-wetland portion of the 100-year floodplain by 0.50;
(f) Steep Slopes: multiply the acreage of land with natural ground slopes exceeding 25 percent by 0.80;
(g) Moderately Steep Slopes: multiply the acreage of land with natural ground slopes of between 15 and 25 percent by 0.40.
2. If a portion of the tract contains more than one natural feature subject to a density factor, that acreage shall be subject to the most restrictive density factor.
3. Since acreage that is contained within the public or private rights-of-way, access easements or access strips is excluded from developable lot area, any portion of these items that also contains a natural feature subject to a deduction from the total tract acreage should not be included when calculating the adjusted tract area.
4. Permitted Dwelling Units: The maximum number of permitted dwelling units equals the Adjusted Tract Area multiplied by the density factor, rounded to the lower number.
C. Country Lot Option: The maximum density shall be one dwelling unit per four (4) acres, calculated on the gross tract acreage.
