Front Yard. There shall be a front yard of not less than 40 feet, except that where the existing buildings on the same side of the street and within 300 feet from each side line, exclusive of streets or private roads, form an irregular setback line, new buildings may conform to the average of such irregular setback lines, provided that no new building may project closer than 30 feet to the street or road property line nor need setback more than 40 feet from the property line. A less than required setback line for an existing principal building may be extended laterally along the line, provided that the front yard toward the street property line is not further encroached upon and that the side line requirements are observed.
c.
Side Yards. There shall be two side yards, and no side yard shall be less than 10 feet. These requirements shall apply for a new building and for an alteration to an existing building. Additions to dwellings with insufficient side yard setbacks, existing on April 21, 1997, shall be permitted if the dwelling is set back at least eight feet from the side property line and if the addition is no closer to the side property line than the existing structure.
d.
Rear Yard. There shall be a rear yard of at least 40 feet. This requirement shall apply for a new building and for an alteration to an existing building.
e.
Access Corridor. No lot shall have a street frontage of less than 50 feet. The width of any corridor providing access to a street shall be at least 50 feet at all points.

j.
Surface Disturbance. Disturbance of land containing slopes over 15% shall be limited as per the following table, based on ten-foot contour intervals, as shown on a grading plan. The ten-foot contour intervals utilized to establish these categories should be those which result in the greatest slope, rather than simply using those contours which are multiples of 10.
Maximum Surface Disturbance per Lot Shall Not Exceed the Greater of: | ||
|---|---|---|
Slope Category | Percent of Category | Square Feet |
15 - 24.99% | 20% | 1,000 |
25 - 29.99% | None | 500 |
