A zoning permit shall be required for all construction and development
in the Floodplain District, which includes but is not limited to buildings
or other structures, paving, filling, grading, excavation, mining,
dredging, or drilling operations.
A. Prior to the issuance of any zoning permit, the Zoning Administrator
shall review the application for permit to determine if all other
necessary government permits required by State and Federal Laws have
been obtained, such as those required by the Pennsylvania Sewage Facilities
Act (Act 1966-537), as amended; the Pennsylvania Dam Safety and Encroachments
Act (Act 1978-325, as amended); the Pennsylvania Clean Streams Act
(Act 1937-394, as amended); the U.S. Clean Water Act, Section 404,
33 U.S.C. § 1334. No permit shall be issued until this determination
has been made.
B. If any proposed construction or development is located entirely or
partially within any identified floodplain area, applicants for zoning
permits shall provide all the necessary information in sufficient
detail and clarity to enable the Zoning Administrator to determine
that:
(1)
All such proposals are consistent with the need to minimize
flood damage and conform with the requirements of this Part and all
other applicable codes and ordinances;
(2)
All utilities and facilities, such as sewer, gas, electrical,
and water systems, are located and constructed to minimize or eliminate
flood damage; and
(3)
Adequate drainage is provided so as to reduce exposure to flood
hazards.
C. Plans on all proposed buildings, structures, and other improvements,
drawn at suitable scale, showing the following:
(1)
The proposed lowest floor elevation of any proposed building
based on the National Geodetic Vertical Datum in the most recent FIS.
(2)
The elevation of the one-hundred-year flood.
(3)
Detailed information concerning any proposed floodproofing measures.
D. For any proposed construction or development located entirely or
partially within any identified floodplain area, applicants for building
permits shall provide the following:
(1)
Documentation, certified by a registered professional engineer
or architect, to show that the cumulative affect of the proposed development,
when combined with all other existing and anticipated development,
will not increase the elevation of the one-hundred-year flood more
than one foot at any point.
(2)
A document, certified by a registered professional engineer
or architect, which states that the proposed construction of a development
has been adequately designed to withstand the one-hundred-year flood
elevations, pressures, velocities, impact and uplift forces associated
with the one-hundred-year flood. Such statement shall include a description
of the type and extent of floodproofing measures which have been incorporated
into the design of the structure and/or the development.
(3)
The location of all existing and proposed buildings, structures,
and other improvements, including the location of any existing or
proposed subdivision and land development.
[Ord. 84-14, 12/18/1984; as amended by Ord. 88-2, 2/23/1988;
and by Ord. 2007-3, 9/18/2007]
1. Purpose. The purpose of these provisions is to prevent the loss of
property and life, the creation of health and safety hazards, the
disruption of commerce and governmental services, the extraordinary
and unnecessary expenditure of public funds for flood protection and
relief, and the impairment of the tax base by:
A. Regulating uses, activities, and development which, acting alone
or in combination with other existing or future uses, activities,
and development, will cause unacceptable increases in flood heights,
velocities, and frequencies.
B. Restricting or prohibiting certain uses, activities, and development
from locating within areas subject to flooding.
C. Requiring all those uses, activities, and developments that do occur
in floodprone areas to be protected and/or floodproofed against flooding
and flood damage.
D. Protecting individuals from buying lands and structures which are
unsuited for intended purposes because of flood hazards.
2. Applicability. These provisions shall apply to all lands within the jurisdiction of Mifflinburg Borough and shown as being located within the boundaries of any identified Floodplain District which is considered as a part of the Official
Zoning Map.
3. Compliance. No structure or land located within an identified Floodplain
District shall be used, located, relocated, constructed, reconstructed,
enlarged, or structurally altered except in full compliance with these
regulations and any other applicable ordinances and regulations.
4. Warning and Disclaimer of Liability. The degree of flood protection
sought by the provisions of this Chapter is considered reasonable
for regulatory purposes and is based on acceptable engineering methods
of study. Larger floods may occur on rare occasions. Flood heights
may be increased by man-made or natural causes, such as ice jams and
bridge openings restricted by debris. This Chapter does not imply
that areas outside the identified floodplain districts, or that land
uses permitted within such districts, will be free from flooding or
flood damage. This Chapter shall not create liability on the part
of Mifflinburg Borough or any officer or employee thereof for any
flood damages that result from reliance on this Chapter or any administrative
decision lawfully made thereunder.

consist of the following specific areas:
A. FE (Special Floodplain Area). The areas identified as Zone AE in
the Flood Insurance Study, where one-hundred-year flood elevations
have been provided, but no floodway has been delineated.
B. FA (General Floodplain Area). The areas identified as Zone A in the
FIS for which no one-hundred-year flood elevations have been provided.
When available, information from other federal, state, and other acceptable
sources shall be used to determine the one-hundred-year elevation,
as well as a floodway area, if possible. When no other information
is available, the one-hundred-year elevation shall be determined by
using a point on the boundary of the identified floodplain area which
is nearest the construction site in question. In lieu of the above,
the municipality may require the applicant to determine the elevation
with hydrologic and hydraulic engineering techniques. Hydrologic and
hydraulic analyses shall be undertaken only by professional engineers
or others of demonstrated qualifications, who shall certify that the
technical methods used correctly reflect currently accepted technical
concepts. Studies, analyses, computations, etc., shall be submitted
in sufficient detail to allow a thorough technical review by the Borough.
2. Overlay Concept.
A. The Floodplain District shall be an overlay to the existing underlying districts as shown on the Official
Zoning Map; and, as such, the provisions for the Floodplain District shall serve as a supplement to the underlying district provisions.
B. Where there happens to be any conflict between the provisions or
requirements of the Floodplain District and those of any underlying
district the more-restrictive provisions shall apply.
3. Floodplain District Map. The boundary of the Floodplain District
is established as shown on the FIA Flood Hazard Boundary Map for Mifflinburg
Borough, which is declared to be a part of this Chapter and which
shall be kept at the Borough Office.
4. Changes in Identification of Area. The identified floodplain area
may be revised or modified by the Borough where studies or information
provided by a qualified agency or person document the need for such
revision. However, prior to any such change, approval must be obtained
from the Federal Emergency Management Agency (FEMA).
