B. 
In order to maintain the quality of surface and ground waters and the open space character of the Town and to protect the public health and safety, natural resource characteristics and suitability of soils for septic tank absorption fields shall be considered in determining a two-acre equivalent minimum buildable lot area. The contribution to the minimum buildable lot area by areas of the lot exhibiting the natural resource characteristics listed below shall be determined by multiplying the area in acres occupied by each resource characteristic by the indicated percentage. The minimum buildable lot area requirement is met when the sum of the contributions of all resource characteristics is at least two acres (see Appendix B).[2] At least 1 1/2 acres of the minimum buildable lot area shall be composed of a soil(s) belonging to Class A, B, C or D. The soils belonging to Class A, B, C or D comprising the 1 1/2 acres of the minimum buildable lot area shall be contiguous. In the case of soils with limitations for septic tank absorption fields, management practices are required to overcome the limitations.
