A.
The municipality is divided into the districts stated
on the Table of Districts, Uses and Lot Requirements,[1] as shown by the district boundaries on the Zoning Map.
[1]
Editor's Note: The Table of Districts, Uses and Lot Requirements is included at the end of this chapter.
B.
Floodplain districts.
[Added 6-12-1979 by Ord. No. 569A]
(1)
Basis of floodplain districts. The various floodplain
districts shall include areas subject to inundation by waters of the
one-hundred-year flood. The basis for the delineation of these districts
shall be the Flood Insurance Study for the Borough of Dravosburg prepared
by the Federal Insurance Administration dated December 15, 1978.
(a)
The Floodway District (FW) is delineated for
purposes of this chapter using that criterion of a certain area within
the floodplain must be capable of carrying the waters of the one-hundred-year
flood without increasing the water surface elevation of that flood
more than one foot at any point. The areas included in this district
are specifically defined in the floodway data table of the above-referenced
Flood Insurance Study shown on the accompanied Flood Boundary and
Floodway Map.
(b)
The Flood-Fringe District (FF) shall be that
area of the one-hundred-year floodplain not included in the floodway
district. The basis for the outermost boundary of this district shall
be the one-hundred-year flood elevation contained in the flood profiles
of the above-referenced Flood Insurance Study (FIS) and as shown on
the accompanied Flood Boundary and Floodway Map.
(c)
The General Floodplain District (FA) shall be
that floodplain area for which no detailed flood profiles and elevations
are provided. Such areas are shown on the maps accompanying the FIS
prepared by the FIA. In determining the necessary elevations for the
purposes of this chapter, other sources of data may be used, such
as:
(2)
Overlay concept.
(a)
The floodplain districts described above shall
be overlays to the existing underlying districts as shown on the Official
Zoning Ordinance Map, and, as such, the provisions for the floodplain
districts shall serve as a supplement to the underlying district provisions.
(b)
Where there happens to be any conflict between
the provisions or requirements of any of the floodplain districts
and those of any underlying district, the more restrictive provisions
and/or those pertaining to the floodplain districts shall apply.
(c)
In the event that any provision concerning a
floodplain district is declared inapplicable as a result of any legislative
or administrative actions or judicial discretion, the basic underlying
district provision shall remain applicable.
(3)
Boundary changes. The delineation of any of the floodplain
districts may be revised by the governing body where natural or man-made
changes have occurred and/or more detailed studies conducted or undertaken
by the U.S. Army Corps of Engineers, a River Basin Commission or other
qualified agency or individual documents the notification for such
change. However, prior to any such change, approval must be obtained
from the Federal Insurance Administration (FIA).
A.
District boundaries shown on the lines of roads, streams,
and transportation rights-of-way shall be deemed to follow the center
lines. The vacation of roads shall not affect the location of such
district boundaries. When the Zoning Officer cannot definitely determine
the location of a district boundary by such center lines, by the scale
or dimensions stated on the Zoning Map, or by the fact that it clearly
coincides with a property line, he shall refuse action, and the Zoning
Hearing Board, upon appeal, shall interpret the location of the district
boundary with reference to the scale of the Zoning Map and the purposes
set forth in all relevant provisions of this chapter.
B.
Interpretation of district boundaries. Initial interpretations
of the boundaries of the floodplain districts shall be made by the
Zoning Officer. Should a dispute arise concerning the boundaries of
any of the Districts, the Zoning Hearing Board shall make the necessary
determination. The person questioning or contesting the location of
the district boundary shall be given a reasonable opportunity to present
his case to the Board and to submit his own technical evidence if
he so desires.
[Added 6-12-1979 by Ord. No. 569A]
The permitted uses for each district are shown
on the Table of Districts, Uses and Lot Requirements.[1] Uses not specifically listed shall not be permitted.

The governing body may authorize conditional uses as specified in the Table of Districts, Uses and Lot Requirements if all conditions and provisions of Article IV are met.
No structure shall exceed 45 feet in height
above average ground level unless approved by the Zoning Hearing Board.

district if:
A.
All front, side, and rear yard depths are increased
one foot for each additional foot of height; or
B.

area of less than 700 square feet.
The minimum lot area, minimum width of lot,
minimum depth of front yard, and minimum width of each side yard for
each district shall be as shown on the Table of Districts, Uses and
Lot Requirements.[1]
A.
Lots which abut on more than one street shall be required
to comply with front yard requirements only along the street on which
the front door of the home and/or structure is located.

structure or not, and whether open or enclosed, including porches,
carports, balconies, or platforms above normal grade level, shall
not project into any minimum front, side, or rear yard.
C.
Any lot of record existing at the effective date of
this chapter and then held in separate ownership different from the
ownership of adjoining lots may be used for the erection of a structure
conforming to the use regulations of the district in which it is located,
even though its area and width are less than the minimum requirements
of this chapter.
D.
Where an on-lot septic tank is to be used, reference
should be made to standards used by the Allegheny County Health Department.
However, in no case shall the lot size be less than 1/2 acre.
E.
Nonresidential structures or uses shall not be located
or conducted closer to any lot line of any other lot in any R District
than the distance specified in the following schedule:
|
