[Zoning Regs. §15.010; Ord. No. 1014 §3, 6-12-1998]
A. The
regulations and requirements as to height of buildings and areas of
lots, which may be occupied by buildings, front yards, side yards,
rear yards and other regulations and requirements as set out in the
foregoing sections of this Chapter, shall be subject to the following
exceptions and additional regulations:
1. Height. Parapet walls and false mansards shall not
exceed more than eight and one-half (8½) feet above the height
limit. Flagpoles, chimneys, cooling towers, elevator bulkheads, penthouses,
finials, gas tanks, grain elevators, stacks, storage towers, radio
towers, ornamental towers, monuments, cupolas, domes, spires, standpipes
and necessary mechanical appurtenances may be erected as to a height
in accordance with existing or hereafter adopted ordinance of the
Board of Aldermen of the City of Platte City, provided that written
approval for such construction is given by the Federal Aviation Agency,
if required.
2. Yard.
a. In Districts "R1-8", "R1-16", "R1-40", "R-2", "R-3" and "R-4" where
lots comprising fifty percent (50%) or more of the frontage on the
same side of the street between two (2) intersecting streets, (excluding
reverse corner lots) are developed with buildings having front yards
with a variation of not more than ten (10) feet in depth, the average
of such front yard shall establish the minimum front yard depth for
the entire frontage. Provided that the Board of Zoning Adjustment
may establish a reasonable setback in case of hardship or where the
configuration of the ground and buildings is such as to make conformity
with the front yard requirements impractical.
b. In Districts "A-1", "R1-40", "R1-16", "R1-8" "R-2", "R-3", "R-4",
"C-1", "C-2", "M-1" and "M-2", where buildings located in the same
block on the same side of the street have provided front yards of
greater or less depth than herein required, the Planning Commission
and Board of Aldermen may establish setbacks for buildings or structures
constructed hereafter.
c. Every part of a required yard or court shall be open from its lowest
point to the sky unobstructed, except for the ordinary projection
of the cells, belt courses, cornices, chimneys, buttresses, ornamental
features and eaves; provided however, that none of the above projections
shall extend into a court more than six (6) inches nor into a minimum
yard more than twenty-four (24) inches; and provided further, that
canopies or open porches having a roof area not exceeding sixty (60)
square feet may project a maximum of six (6) feet into the required
front or rear yard; and existing open porches extending into the required
yard shall not be enclosed.
d. An open fire escape may project into a required side yard not more
than half the width of such yard, but not more than four (4) feet
from the building. Fire escapes, solid-floored balconies and enclosed
outside stairways may project not more than four (4) feet into a rear
yard. A below grade exterior stairway shall have a rail not less than
three (3) feet in height surrounding the below grade area.
e. On any lot no topographical grade nor wall, sign nor other structure,
nor plant growth of any type which would interfere with visibility
of drivers on the public street shall be permitted or maintained higher
than three (3) feet above the adjacent curve level from the front
of the house forward to the pavement.
f. No rear yard shall be required in Districts "C-1", "C-2", "M-1" and
"M-2" inclusive on any lot used for business or industrial purposes,
the rear line of which adjoins a railway, right-of-way or which has
a rear railway track connection.
g. In computing the depth of a rear yard for any building where such
yard abuts an alley, one-half (½) of such alley may be assumed
to be a portion of the rear yard.
h. A through lot having one (1) end abutting a limited access highway
or thoroughfare with no access permitted to that lot from said highway
shall be deemed to front upon the street which gives access to that
lot.
