No structure shall be erected or used, premises used, or lot
changed in size or shape except in conformity with the requirements
of this section, unless exempted by this chapter or by statute.
The following shall apply when calculating dimensional requirements:
181.4121.
Lot area. Lot area shall be determined by calculating the area
within a lot, including any area within the lot over which easements
have been granted, provided that no area within a street shall be
included in determining minimum lot area.
181.4122.
Frontage. Frontage shall be measured in a continuous line along
the side line of a street between the points of intersection of the
side lot lines with the street.
A. Frontage for a corner lot may be measured either to the point of
intersection of the extension of the side line of the rights-of-way
or to the middle of the curve connecting the side line of the intersecting
streets.
B. If a lot has frontage on more than one street, the frontage on one
street only may be used to satisfy the minimum lot frontage.
181.4123.
Lot width. Lot width shall be determined by measuring the diameter
of the largest circle which can be located at all points along a continuous
but not necessarily straight line from the lot frontage to the principal
structure on the lot (or the front yard setback if there is no structure)
without the circumference intersecting the side lot lines.
181.4124.
Corner clearance. On a corner lot in any district, in order
that visibility is unobstructed at intersections, no sign fence, wall,
tree, hedge, or other vegetation between three and eight feet above
the established street grades shall be erected, placed or maintained
within the triangular area formed by the intersecting street lines
and a straight line adjoining such street lines at points which are
20 feet distance from the point of intersection measured along such
street lines.
181.4125.
Lot Shape. No lot in a residential zoning district shall be
created to be so irregularly shaped or extended that it has a lot
shape factor less than .40. In determining the lot shape factor for
rear lots, the formula shall not include the perimeter or area of
the access strip. The access strip shall be defined as that section
of a lot which connects the buildable area of a rear lot with its
frontage. For the purposes of determining a lot shape factor, access
strips shall be measured from where the side lot lines meet the frontage
line and end where the side lot lines widen to the minimum required
frontage width of the zoning district in which the lot is located.
The lot shape factor is defined as the lot area multiplied by 16 and
divided by the square of the lot perimeter.
Lot Shape Factor Formula: P = lot perimeter and A = lot area.
|
Lot Shape Factor = 16(A)/P2
|
181.4126.
Front yards. Front yards shall be the distance, measured in
a straight line, between the lot frontage and the nearest point of
the principal building or any structure attached to the principal
building, including garages. A lot having frontage on two or more
streets shall have two or more front yards, each of which shall comply
with the requirements of the front yard provisions. In no case shall
any building or structure be located closer to the sideline of a street
than the minimum required front yard.
181.4127.
Side and rear yards. Side and rear yards shall be the distance,
measured in a straight line, from the nearest point of any principal
building or structure to each side or rear lot line.
181.4128.
Merging of Nonconforming Lots. Nonconforming lots held in common
ownership with contiguous lots shall be considered merged for zoning
purposes
On a corner lot in any district, in order that visibility is
unobstructed at intersections, no sign fence, wall, tree, hedge, or
other vegetation between three and eight feet above the established
street grades shall be erected, placed or maintained within the triangular
area formed by the intersecting street lines and a straight line adjoining
such street lines at points which are twenty feet distance from the
point of intersection measured along such street lines.
Except as otherwise provided herein, not more than one principal
structure may be placed on any lot.
The minimum lot frontage for a lot may be reduced to fifty feet per lot, provided that each lot front is entirely on a cul-de-sac with a right-of-way layout radius of 67.5 feet or greater and, further, provided that no more than five such reduced frontage lots shall have frontage on a cul-de-sac and, further, provided that each such lot shall have twice the lot area required. (See also Section
181.75, Rear Lots.)
When permitted herein, more than one principal structure may
be erected on a lot, subject to the following conditions:
181.4231.
No principal structure shall be located in relation to another
principal structure on the same lot, or on an adjacent lot, so as
to cause danger from fire;
181.4232.
All principal buildings on the lot shall be served by access
ways suitable for fire, police, and emergency vehicles;
181.4233.
All of the multiple principal buildings on the same lot shall
be accessible via pedestrian walkways connected to the required parking
for the premises, and to each principal building.
Where a district boundary line divides any lot existing at the
time such line is adopted, the regulations of any district in which
the lot has frontage on a street may be extended by special permit
from the Board of Appeals not more than 30 feet into the other district;
provided, however, that residential uses may be extended as of right
into the other district not more than 30 feet.
Notwithstanding the provisions of Section
181.416 (Table of Dimensional Requirements), structures in the C, AI, and I Districts may exceed the stated maximum height with the issuance of a special permit from the applicable special permit granting authority (SPGA), provided the SPGA makes a finding that additional height is necessary to accomplish the intended purpose of the structure and is not injurious to the surrounding uses.
The Planning Board may grant a special permit allowing the exceptions from the provisions of this chapter described in Sections
181.4271 through
181.4273 for principal and accessory uses and structures proposed on lots in the Commercial Recreation District (CR) and the University District (FSU) if such lots have an area of greater than 40,000 square feet. The Planning Board may grant the special permit upon written findings, in its decision, that the lot and the exceptions applied for meet the criteria for issuance of a special permit described in Section
181.94. In granting the special permit, the Planning Board may impose conditions on building and on site design in order to ensure that the site and the building, on completion of the proposed project, is compatible with the architectural and landscape design of properties in the surrounding neighborhood and consistent with the improvement of the CR or FSU District.
181.4271.
Notwithstanding the provisions of Section
181.31, Principal Uses, the Planning Board may permit more than one principal use including residential use on a single lot and more than one principal use in a single structure.
181.4272.
Notwithstanding the provisions of Section
181.415, One Structure per Lot, the Planning Board may permit more than one principal structure on a single lot.
181.4273.
Notwithstanding the provisions of Section
181.416, Table of Dimensional Requirements, the Planning Board may permit structures with a front setback of less than 15 feet and a height no greater than 100 feet.
Notwithstanding the provisions of Section
181.416 (Table of Dimensional Requirements), motor vehicle and equipment sales shall be located on a lot with at least 10,000 square feet in area.
