Every part of a required yard must be unobstructed except for plantings, accessory buildings in a rear or side yard and ordinary projections of open porches, balconies, steps, sills, cornices, ornamental features projecting not more than 12 inches and covered in-ground facilities such as septic systems.
A. Permitted obstructions. Fences or walls not over six and 6 1/2 feet in height may be erected anywhere on the lot, except within clear-sight triangles. Fences or walls with a height in excess of 6 1/2 feet shall conform to the requirements set forth herein for buildings. Paved areas (other than such as are needed for access to the buildings on the lot) shall not project within 15 feet of a street line or four feet of a lot line.
B. Front yards on narrow streets. On streets with less than fifty-foot right-of-way, the front yard requirement shall be measured from the center line of the existing roadway and 25 feet shall be added to the front yard requirement.
C. Side yards. Side yard width may be varied. Where the side wall of a building is not parallel with the side lot lien or is broken or otherwise irregular, the side yard may be varied. In such cases, the average width of the side yard shall not be less than the otherwise required minimum width; provided, however, that such side yard shall not be narrower at any one point than 1/2 the otherwise required minimum width.
Land coverage by principal or accessory buildings or structures on each zone lot shall not be greater than is permitted in the district where such buildings are located. Land cleared for purposes of building shall be improved landscaped or otherwise protected from erosion. Other clearing activities are not regulated by this chapter.
