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
for lots newly created after the effective date of this chapter, except
that in conventional subdivisions in the RA District, a maximum of
25% of the minimum lot area may consist of wetlands.
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.
D.
Driveway setbacks. Driveways on lots with 100 feet
or more of road frontage shall be set back at least 10 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.
E.
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, 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. The requirements of this subsection do not apply to exempt agricultural structures under § 220-37C.
F.
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;
(b)
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;
(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.
G.
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.
H.
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.
(2)
The setback requirements of this chapter shall not
apply to any front yard fences or walls less than four feet high,
except that customary agricultural wire, board, or split rail fencing
which does not obstruct visibility may be higher.
I.
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
in the RA, CLI or HC District 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.
J.
Reduction in lot area. No conforming lot shall be
reduced in area in a manner that violates the dimensional requirements
of this chapter.
