(b) 
A building permit shall not be required for minor repairs to existing buildings or structures.
(2) 
Abrogation and greater restrictions. This section supersedes any other conflicting provisions that may be in effect in identified floodplain areas. However, any other section's provisions shall remain in full force and effect to the extent that those provisions are more restrictive. If there is any conflict between any of the provisions of this section, the more restrictive shall apply.
(3) 
Severability. If any section, subsection, paragraph, sentence, clause or phrase of this section shall be declared invalid for any reason whatsoever, such a decision shall not affect the remaining portions of this section, which shall remain in full force and effect; and for this purpose, the provisions of this section are hereby declared to be severable.
(4) 
Warning and disclaimer of responsibility. The degree of flood protection sought by the provisions of this section 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 section does not imply that areas outside any identified floodplain areas or that land uses permitted within such areas will be free from flooding or flood damages. This section shall not create liability on the part of the Municipality or any officer or employee thereof for any flood damages that result from reliance on this section or any administrative decision lawfully made thereunder.
(5) 
Compliance. No structure or land shall hereafter be used and no structure shall be located, relocated, constructed, reconstructed, enlarged or structurally altered except in full compliance with the terms and provisions of this chapter and any other applicable ordinances and regulations that apply to uses within the jurisdiction of this chapter.
D. 
Definition of floodplains.
(1) 
Identification. The identified floodplain area shall be any areas of the Municipality of Murrysville classified as special flood hazard areas (SFHAs) in the Flood Insurance Study (FIS) and the accompanying Flood Insurance Rate Maps (FIRMs), dated _____ and issued by the Federal Emergency Management Agency (FEMA), or the most-recent revisions thereof, including all digital data developed as part of the Flood Insurance Study. The above-referenced FIS and FIRMs, and any subsequent revisions and amendments, are hereby adopted by the Municipality of Murrysville and declared to be a part of this chapter.
(2) 
Description. The identified floodplain areas shall consist of the following specific areas:
(a) 
FW (Floodway Area). The areas identified as "floodway" in the AE Zone in the Flood Insurance Study prepared by the FEMA. The term shall also include floodway areas that have been identified in other available studies or sources of information for those floodplain areas where no floodway has been identified in the Flood Insurance Study.
(b) 
FF (Flood-Fringe Area). The areas identified as Zones AE and A1-30 in the FIS which are subject to inundation by the one-percent-annual-chance flood event, determined by detailed methods, and which have base flood elevations (BFEs) shown.
(c) 
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 that 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 Municipality.
(d) 
Boundary disputes. Should a dispute concerning any identified floodplain boundary arise, an initial determination shall be made by the Municipality's Planning Commission, and any party aggrieved by this decision may appeal to the Council. The burden of proof shall be on the appellant.
(3) 
Application. The provisions in this section shall apply to any land use within any floodplain.
E. 
Procedures.
(1)

[2] 
Except for a possible modification of the one-and-one-half-foot freeboard requirement involved, no variance or special exception shall be granted for any of the other requirements pertaining specifically to development regulated by special permit or to development that may endanger human life. [See Subsection F(6).]
[3] 
If granted, a variance shall involve only the least modification necessary to provide relief.
[4] 
In granting any variance, the Zoning Hearing Board shall attach whatever reasonable conditions and safeguards it considers necessary in order to protect the public health, safety and welfare and to achieve the objectives of this section.
[5] 
Whenever a variance is granted, the Zoning Hearing Board shall notify the applicant in writing that:
[a] 
The granting of the variance may result in increased premium rates for flood insurance.
[b] 
Such variances may increase the risks to life and property.
[6] 
In reviewing any request for a variance, the Municipality shall consider, at a minimum, the following:
[a] 
That there is good and sufficient cause.
[b] 
That failure to grant the variance would result in exceptional hardship to the applicant.

I. 
Standards. All activity in this district shall be required to meet the standards of the land operations regulations.
The purpose and intent of this article is to protect wetland systems and sustain wetland hydroperiods, to minimize activities that degrade, destroy or otherwise negatively impact wetland values and functions and, where appropriate, to reestablish and restore productive wetland systems. Further, it is the purpose and intent of this article to promote ecological stability, improve water quality, prevent flooding and protect property and environmental resources. Wetlands serve many important hydrological and ecological values and functions. They reduce the impact of flooding by acting as natural retention and water storage areas. Wetlands act as groundwater recharge areas and protect water supplies for environmental, urban and agricultural use. Wetlands protect groundwater table levels and help minimize damage from fires. Wetlands provide inflows of clean water to the rivers and estuaries through surface and groundwater connections and minimize urban runoff by filtering water. They provide green space and biological diversity and serve to cool the atmosphere. Wetlands act as productive biological systems, providing habitat for a variety of animal species. Wetlands are important to our community values and aesthetic appearance.
