A.
Wetlands in lot area calculations. In computing minimum lot sizes pursuant to the Dimensional Table, the area of wetlands shall be subtracted from total acreage in the lot area calculation.
B.
Corner lots and through lots. Wherever a side or rear yard is adjacent to a street, the front setback shall apply to such side or rear yard. Corner lots shall be deemed to have two front yards, two side yards, and no rear yard.
C.
Projections into required yards.
(1)
The following projections into required yards shall be permitted:
(2)
Carport. An open or enclosed carport shall be considered a part of the building in determining compliance with setback requirements.

(4)
Driveways. Driveways on lots with 100 feet or more of road frontage shall be set back at least 20 feet from side lot lines, except that common driveways may occupy any part of a side yard adjoining the lot of another user of the common driveway. On lots with less than 100 feet of frontage, no side yard setback shall be required.
D.
Height exceptions.
(1)
The height limitations in the Dimensional Table shall not apply to any flagpole, radio or television receiving antenna, spire or cupola, chimney, elevator or stair bulkhead, parapet or railing, water tank, or any similar nonhabitable structure, provided that such structure is firmly attached to the roof or side of a building and covers no more than 10% of the roof area.
(2)
Barns, silos, solar energy systems, communication towers, and wind energy conversion systems may exceed height limits in the Dimensional Table, provided that they comply with applicable sections of this Article VII, and provided that for every one foot by which such structures exceed the height limit, the minimum setback requirements are increased by one foot.
E.
Setbacks for accessory structures and uses.
(1)
Any accessory structure attached to a principal building and any detached barn, garage, stable, tennis court, or swimming pool shall comply with the minimum setback requirements of this chapter applicable to the principal building. Other detached accessory structures or uses may encroach into required setback areas provided that they:
(a)
Are not used for human habitation;

Have a footprint no larger than 200 square feet;
(c)
Do not exceed 16 feet in height;
(d)
Do not occupy more than 10% of a rear setback area;
(e)
Are set back at least 10 feet from side or rear lot lines;
(f)
Are not located closer to the street than the front yard setback required for a principal building, except for fences, gates, mailboxes, newspaper receptacles, signs, sand storage bins, bus shelters, and similar roadside structures with less than 100 square feet of footprint, as well as ornamental structures such as entry pillars and statues; and
(g)
Are not used for housing animals.
(2)
For corner lots, the setback from all streets shall be the same for accessory structures as for principal buildings.
F.
Setbacks involving irregular buildings and lot lines. Where structures or lot lines are irregular or unusual in configuration, all points on the structure shall satisfy the minimum setback requirements from that point on the lot line which is the shortest distance from the structure.
G.
Fences (including hedges) and walls.
(1)
The setback requirements of this chapter shall not apply to retaining walls of any height or to fences less than six feet high in any side or rear yard, except where corner clearances are required for traffic safety.

H. 
Corner clearance/visibility at intersections. Where necessary to provide visibility for traffic safety, the Highway Superintendent or the Planning Board may require all or a portion of any corner lot which is shown shaded in Sketch A to be cleared of all growth (except isolated trees) and other obstructions that block visibility of traffic on an intersecting street. The Planning Board may require excavation to achieve visibility. This provision shall not apply to intersections with traffic signals or four-way stop signs.

I.
Reduction in lot area. No conforming lot shall be reduced in area in a manner that violates the dimensional requirements of this chapter.
