The Commission may approve a new lot which does not meet all of the criteria in § 315-20.1 for net buildable lot area if the Commission determines that there is a suitable existing area on the proposed lot with soils and other conditions which will permit the construction of an on-site non-engineered subsurface sewage disposal system and reserve area, and if the Commission further finds that there is adequate additional area within the lot for construction of a dwelling and access without extensive grading or filling.
