Mathematical determination of yield. The mathematical determination of yield is intended to be a simplified method to determine the maximum number of dwelling units allowed on the parcel(s). The mathematical determination of yield is calculated as follows:
Step 1: Determine presumed area of developable land. Based on the material shown on and submitted with the base plan, the applicant shall work with the Planning Board to determine the presumed area of developable land.
Step 2: Calculate presumed amount of developable land. The mathematical determination of yield assumes 30% of the developable land area is needed for infrastructure improvements. For the purposes of the mathematical determination of yield, the presumed area of developable land determined in Step 1 is multiplied by 70% to indicate the total amount of developable land.
Example: On a 100-acre parcel, 60 acres are determined, after working with the Planning Board, to be the presumed area of developable land. The presumed amount of developable land is 42 acres (60 x 0.7).
Step 3: Calculate the maximum number of allowable lots. The maximum number of allowable lots is determined by taking the presumed amount of developable land and dividing it by the minimum lot area requirement in the zoning district as shown in Section 4.0, Schedule of Dimensional Requirements.
Example: From the example above, the amount of developable land is 42 acres. The minimum lot size in the R4 District is two acres. Therefore, the maximum number of allowable lots is 21 (42 ÷2.0).
