A. Except as provided in subsection C of this section, the maximum numbers of dwelling units proposed for a residential cluster development shall not exceed the number of dwelling units otherwise permitted for the Residential Zoning District in which the parcel is located.
B. Except as provided in subsection C of this section, the number of permitted dwelling units on a site shall be calculated in the following manner.
1. Measure the gross area of the proposed cluster development site in acres and tenths of an acre;
2. Subtract from the gross area determined in subsection B1 of this section the area of public and private streets and other publicly dedicated improvements, measured in acres and tenths of an acre, excluding common open space. The remainder shall be the net buildable area;
3. Convert the net buildable area from acres to square feet (SF), using the equivalency of 43,560 SF = 1 acre; and
4. Divide the net buildable area by the smallest minimum lot size (in square feet) per unit for a dwelling unit permitted in the zoning district. This figure shall be rounded to the nearest lower number to establish the maximum number of dwelling units to be permitted in the cluster development.
C. An increase of up to a minimum of one unit or ten percent (10%), whichever is greater, of the maximum number of dwelling units in the cluster development, as calculated in subsection B of this section, may be approved if the percent of density bonus is no greater than the percent of the gross area of the cluster development that is set aside and conveyed as common open space pursuant to section 15.340.08 of this title.
D. Additional density may be approved when the requirements of chapter 115, "Density Bonus Agreements", of this title, are met. (Ord. 603, 11-1-2018)
