For each one foot of difference in elevation greater than 10 feet between points A and B described in this section, the minimum required lot area and lot width for a lot within a Hillside Overlay shall be increased three percent over the minimum area and minimum width prescribed in the base residential zoning district.

Point A is the point at which a projected side lot line intersects the edge of the existing roadway. Point B is the point on the site 100 feet distant from Point A with the greatest difference in elevation.
