Muncy City Zoning Code
ARTICLE VI
Supplementary Floodplain Management Regulations
§ 286-56 General provisions.
A.
Purpose. The purpose of these provisions is to:
(1)
Promote the general health, welfare and safety of the community;
(2)
Encourage the utilization of appropriate construction practices in order to prevent or minimize flood damage in the future;
(3)
Minimize danger to public health by protecting water supply and natural drainage;
(4)
Reduce financial burdens imposed on the community, its governmental units, and its residents, by preventing excessive development in areas subject to flooding; and
(5)
Comply with federal and state floodplain management requirements.
B.
Compliance. It shall be unlawful for any person, partnership, business or corporation to undertake, or cause to be undertaken, any construction or development within the Borough except in full compliance with the terms and provisions of this chapter, including § 286-94 pertaining to zoning permits, and any other applicable regulations which apply to uses within the jurisdiction of this chapter.
C.
Interpretation of district boundaries. Where interpretation is needed concerning the exact location of any boundary of any floodplain district, the Zoning Hearing Board shall make the necessary determination. Persons contesting the location of the district boundary shall be given a reasonable opportunity to present their case to the Zoning Hearing Board and to submit their own technical evidence if they so desire.
D.
Warning and disclaimer of liability. The degree of flood protection sought by the provisions of this article is considered reasonable for regulatory purposes and is based on acceptable engineering methods of study. Larger floods may occur. 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 floodplain districts, or that land uses permitted within such areas, will be free from flooding or flood damages.
§ 286-57 Basis for floodplain districts.
A.
Identification.
(1)
The identified floodplain shall be those areas of Muncy Borough which are subject to the one-hundred-year flood, as identified in the Flood Insurance Study (FIS) dated March 16, 2004, and the accompanying maps prepared for the Borough by the Federal Emergency Management Agency (FEMA), or the most recent revision thereof.
(2)
For the purposes of this chapter, the Floodway District and the Flood Fringe and General Floodplain District shall be overlays to the existing underlying districts as shown on the Borough's Official Zoning Map. As such, the provisions for theses districts shall serve as a supplement to the underlying district provisions. Where there happens to be any conflict between the provisions or requirements of the floodplain districts and those of any underlying district, the more restrictive provisions and/or those pertaining to the floodplain districts shall apply.
B.
Description of floodplain areas.
(1)
The identified floodplain shall consist of the following specific areas:
(a)
The floodway area includes all those areas of the one-hundred-year floodplain identified as "floodway" in the AE Zone in the FIS prepared by FEMA. The term shall also include those areas which have been identified as floodway in other available studies or sources of information for those floodplain areas where no floodway has been identified in the FIS.
(b)
The flood-fringe area includes all the remaining portions of the one-hundred-year floodplain in those areas identified as an AE Zone in the FIS where a floodway has been delineated. The basis for the outermost boundary of this Area shall be the one-hundred-year flood elevations as shown on the flood profiles contained in the FIS.
(c)
The general floodplain area includes 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 or other acceptable sources shall be used to determine the one-hundred-year flood elevation, as well as a floodway area, if possible. When such other acceptable information is not available, the one-hundred-year flood elevation shall be determined by using the elevation of a point on the boundary of the identified floodplain area which is nearest the construction site.
(2)
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.
§ 286-58 Flood damage control provisions.
In order to prevent excessive damage to buildings and structures due to flooding, the following restrictions shall apply to all new construction, development, and substantial improvement occurring in all designated Floodplain Districts:
A.
General technical requirements.
(1)
Within the identified floodplain areas, the development and/or use of land shall be permitted provided that such development or use complies with the restrictions and requirements of this and all other applicable codes and ordinances in effect in Muncy Borough.
(2)
Within any floodway area, the following provisions shall apply:
(a)
No new construction, development, use, activity or encroachment shall be permitted that would cause any increase in one-hundred-year flood heights.
(b)
No new construction or development shall be allowed unless a permit is obtained from the Department of Environmental Protection's Regional Office.
(3)
Within any general floodplain area, no new construction or development shall be located within the area measured 50 feet landward from the top-of-bank of any watercourse.
(4)
The standards and specifications contained in 34 Pa. Code (the Uniform Construction Code), Chapters 401 through 405, as amended, and the following referenced provisions shall apply to all sections of this article, to the extent that they are more restrictive and/or supplement the requirements of this chapter.

Variances may not be granted for any construction, development, use, or activity within any floodway area that would result in any increase in flood levels during the one-hundred-year flood.
D.
If granted, a variance shall involve only the least modification necessary to provide relief.
E.
In granting any variance, the Borough shall attach whatever reasonable conditions and safeguards it considers necessary to protect the public health, safety and welfare, and to achieve the objectives of this chapter.

§ 286-66 Special exceptions in floodplain districts.
In passing upon applications for special exceptions within any identified floodplain area, the Zoning Hearing Board shall consider all factors specified in other sections of this chapter (including § 286-88D), and the following:
A.
The danger to life and property due to increased flood heights or velocities caused by encroachments. In the Floodway District, no special exception shall be granted which will cause any rise in the elevation of the one-hundred-year flood;
B.
The danger that materials may be swept onto other lands or downstream causing injury to others;
C.
The proposed water supply and sanitation systems and the ability of these systems to prevent disease, contamination, and unsanitary conditions;
D.
The susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the individual owners;
E.
The importance of the services provided by the proposed facility to the community;
F.
The requirements of the facility for a waterfront location;
G.
The availability of alternate locations not subject to flooding for the proposed use;
H.
The compatibility of the proposed use with existing development and development anticipated in the foreseeable future;
I.
The safety of access to the property in times of flooding by ordinary and emergency vehicles;
J.
The expected heights, velocity, duration, rate of rise and sediment transport of the floodwaters expected at the site; and
K.
Such other factors which are relevant to the purposes of this chapter.
