The Legislature of the Commonwealth of Pennsylvania has, by the passage of the Pennsylvania Flood Plain Management Act of 1978,[1] delegated the responsibility to local governmental units to adopt floodplain management regulations to promote public health, safety, and the general welfare of its citizenry. Therefore, the Council of West Conshohocken Borough does hereby order as follows.
[1]
Editor's Note: See 32 P.S. § 679.101 et seq.
A. 
Intent. The intent of this article 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.
(5) 
Comply with federal and state floodplain management requirements.
B. 
Applicability. It shall be unlawful for any person, partnership, business or corporation to undertake, or cause to be undertaken, any construction or development anywhere within the Borough unless a permit has been obtained from the Building Code Official.
C. 
Abrogation and greater restrictions. This article supersedes any other conflicting provisions which may be in effect in identified floodplain areas. However, any other ordinance 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 article, the more restrictive shall apply.
D. 
Severability. If any section, subsection, paragraph, sentence, clause, or phrase of this article shall be declared invalid for any reason whatsoever, such a decision shall not affect the remaining portions of this article, which shall remain in full force and effect, and for this purpose the provisions of this article are hereby declared to be severable.
E. 
Warning and disclaimer of liability.
(1) 
The degree of flood protection sought by the provisions of this article is considered reasonable for regulatory purposes and is based on accepted engineering methods of study. Larger floods may occur or flood heights may be increased by man-made or natural causes, such as ice jams and bridge openings restricted by debris. This article 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.
(2) 
This article shall not create liability on the part of the Borough or any officer, employee, or appointed professional thereof for any flood damages that result from reliance on this article or any administrative decision lawfully made thereunder.

SUBSTANTIAL IMPROVEMENT
Any reconstruction, rehabilitation, addition, or other improvement of a structure, of which the cost equals or exceeds 50% of the market value of the structure before the start of construction of the improvement. This term includes structures which have incurred substantial damage or repetitive loss, regardless of the actual repair work performed. The term does not, however, include any project for improvement of a structure to correct existing violations of state or local health, sanitary, or safety code specifications which have been identified by the local code enforcement official and which are the minimum necessary to assure safe living conditions. Historic structures undergoing repair or rehabilitation that would constitute a substantial improvement as defined in this article, must comply with all ordinance requirements that do not preclude the structure's continued designation as a historic structure. Documentation that a specific ordinance requirement will cause removal of the structure from the National Register of Historic Places or the State Inventory of Historic places must be obtained from the Secretary of the Interior or the State Historic Preservation Officer. Any exemption from ordinance requirements will be the minimum necessary to preserve the historic character and design of the structure.

No new construction or development shall be allowed, unless a permit is obtained from the Department of Environmental Protection regional office.
(2) 
The AE Area/District without floodway shall be those areas identified as an AE Zone on the FIRM included in the FIS prepared by FEMA and for which base flood elevations have been provided in the FIS, but no floodway has been delineated.
(a) 
No permit shall be granted for any construction, development, use, or activity within any AE Area/District without floodway unless it is demonstrated that the cumulative effect of the proposed development would not, together with all other existing and anticipated development, increase the BFE more than one foot at any point.
(3) 
Community-identified flood hazard areas shall be those areas where the Borough has identified local flood hazard or ponding areas, as delineated and adopted on a local flood hazard map using best available topographic data and locally derived information such as flood of record, historic high water marks, soils or approximate study methodologies.
(4) 
A Area/District.
(a) 
The A Area/District shall be those areas identified as an A Zone on the FIRM included in the FIS prepared by FEMA and for which no one-percent-annual chance flood elevations have been provided. For these areas, elevation and floodway information from other federal, state, or other acceptable sources shall be used when available. Where other acceptable information is not available, the base 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.
(b) 
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.
C. 
Changes in identification of area. The identified floodplain area may be revised or modified by the Council where studies or information provided by a qualified agency or person documents the need for such revision. However, prior to any such change to the special flood hazard area, approval must be obtained from FEMA. Additionally, as soon as practicable, but not later than six months after the date such information becomes available, a community shall notify FEMA of the changes to the special flood hazard area by submitting technical or scientific data.

The Borough Council and Zoning Hearing Board shall exercise discretion in allowing only those uses which are substantially in accord with the objectives stated in § 113-85A herein. The Borough Council, in considering a use as a conditional use, or the Zoning Hearing Board, in considering a use by variance, shall utilize the following:
(1) 
No variance shall be granted for any construction, development, use or activity within any floodway area that would cause any increase in the base flood elevation.
(2) 
No variance shall be granted for any construction, development, use, or activity within any AE Area/District without floodway that would, together with all other existing and anticipated development, increase the base flood elevation more than one foot at any point.
(3) 
No variance shall be granted for any of the other requirements pertaining specifically to development regulated by § 113-90C (pertaining to special technical requirements for activities requiring a special permit) or to development which may endanger human life.
(4) 
The effect of the use shall not substantially alter the cross-sectional profile of the stream and floodplains at the location of the proposed use.
(5) 
Lands abutting the waterway, both upstream and downstream, shall not be unreasonably affected by the proposed use.

Affirmative decisions shall only be issued upon determination that it is the minimum necessary, considering the flood hazard, to provide relief.
(13) 
The Zoning Hearing Board or Borough Council shall notify the applicant, in writing, over the signature of community officials, that the issuance of a decision to allow construction of a structure below the base flood elevation will result in increased premium rates for flood insurance and that such construction below the base flood elevation increases risks to life and property. Such notification shall be maintained with a record of all decisions as required in Subsection E(14) of this section.
(14) 
The Borough shall maintain a record of all decisions, including justification for their issuance, and report such decisions issued in its annual report submitted to the Federal Emergency Management Agency (FEMA).
F. 
Additional standards for approval of uses by variance.
(1) 
A property owner of a lot of record, as of the date of the enactment of this article, who is able to prove that the strict enforcement of this article would create undue hardship by denying a reasonable use of an existing lot which is situated either wholly or partially in the Floodplain Conservation District, may seek relief by applying for a variance from the Zoning Hearing Board.
(2) 
The Zoning Hearing Board, after deciding upon the merits of the application, may permit the applicant to make some reasonable use of the property in question, while ensuring that such use will not violate the basic objectives of this article, as specified in § 113-85 herein.
(3) 
In considering a use as a variance, the Zoning Hearing Board shall consider, at a minimum, the following:
(a) 
That there is good and sufficient cause, including:
[1] 
That there are unique physical circumstances or conditions, including irregularity, narrowness, or shallowness of lot size or shape, or exceptional topographical or other physical conditions peculiar to the particular property and that the unnecessary hardship is due to such conditions and not the circumstances or conditions generally created by the provisions of the Zoning Ordinance in the neighborhood or district in which the property is located.
[2] 
That because of such physical circumstances or conditions, there is no possibility that the property can be developed in strict conformity with the provisions of the Zoning Ordinance and that the authorization of a variance is therefore necessary to enable the reasonable use of the property.
[3] 
That such unnecessary hardship has not been created by the appellant.
[4] 
That the variance, if authorized, will not alter the essential character of the neighborhood or district in which the property is located, nor substantially or permanently impair the appropriate use or development of adjacent property, nor be detrimental to the public welfare.
(b) 
That failure to grant the variance would result in exceptional hardship to the applicant.
(c) 
That the granting of the variance will:
[1] 
Neither result in an unacceptable or prohibited increase in flood heights, additional threats to public safety, or extraordinary public expense; nor
[2] 
Create nuisances, cause fraud on, or victimize the public, or conflict with any other applicable state or local ordinances and regulations.
(4) 
A complete record of all variance requests and related actions shall be maintained by the Borough. In addition, a report of all variances granted during the year shall be included in the biennial report to FEMA.
