Editor’s Note: This Part was adopted 3/16/2015 by Ord. No. 2015-5, 3/16/2015, which ordinance superseded former Part 12, Floodplain District Regulations, adopted by Ord. 1999-5, 5/17/1999.
[Ord. 2015-5, 3/16/2015]
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 the Borough of Doylestown does hereby order as follows.
[1]
Editor's Note: See 32 P.S. § 679.101 et seq.
[Ord. 2015-5, 3/16/2015]
1. 
Intent. The intent of this Part is to:
A. 
Promote the general health, welfare, and safety of the community.
B. 
Encourage the utilization of appropriate construction practices in order to prevent or minimize flood damage in the future.
C. 
Minimize danger to public health by protecting water supply and natural drainage.
D. 
Reduce financial burdens imposed on the community, its governmental units, and its residents by preventing excessive development in areas subject to flooding.
E. 
Comply with federal and state floodplain management requirements.
2. 
Applicability.
A. 
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 of Doylestown unless a permit has been obtained from the Floodplain Administrator.[1]
[1]
Editor’s Note: Former Subsection 2B, regarding minor repairs to existing buildings, which immediately followed this subsection, was repealed 3/20/2017 by Ord. 2017-3.
3. 
Abrogation and Greater Restrictions. This Part 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 Part, the more restrictive shall apply.
4. 
Severability. If any section, subsection, paragraph, sentence, clause, or phrase of this Part shall be declared invalid for any reason whatsoever, such a decision shall not affect the remaining portions of this Part, which shall remain in full force and effect, and for this purpose the provisions of this Part are hereby declared to be severable.
5. 
Warning and Disclaimer of Liability.
A. 
The degree of flood protection sought by the provisions of this Part 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 Part 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.
B. 
This Part shall not create liability on the part of the Borough of Doylestown or any officer or employee thereof for any flood damages that result from reliance on this Part or any administrative decision lawfully made thereunder.

[Ord. 2015-5, 3/16/2015]
1. 
Identification.
A. 
The identified floodplain area shall be any areas of the Borough of Doylestown classified as special flood hazard areas (SFHAs) in the Flood Insurance Study (FIS) and the accompanying Flood Insurance Rate Maps (FIRMs) dated March 16, 2015, and issued by the Federal Emergency Management Agency (FEMA) or the most recent revision thereof, including all digital data developed as part of the Flood Insurance Study.
B. 
The above-referenced FIS and FIRMs, and any subsequent revisions and amendments, are hereby adopted by the Borough of Doylestown and declared to be a part of this Part.
2. 
Description and Special Requirements of Identified Floodplain Areas. The identified floodplain area shall consist of the following specific areas:
A. 
The Floodway Area shall be those areas identified in the FIS and the FIRM as floodway and which represent the channel of a watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without increasing the water surface elevation by more than one foot at any point. This term shall also include floodway areas which have been identified in other available studies or sources of information for those special flood hazard areas where no floodway has been identified in the FIS and FIRM.
(1) 
Within any floodway area, no encroachments, including fill, new construction, substantial improvements, or other development, shall be permitted unless it has been demonstrated through hydrologic and hydraulic analysis performed in accordance with standard engineering practice that the proposed encroachment would not result in any increase in flood levels within the community during the occurrence of the base flood discharge.
(2) 
Within any floodway area, no new construction or development shall be allowed, unless the appropriate permit is obtained from the Department of Environmental Protection Regional Office.
B. 
The AE Area/District shall be those areas identified as an AE Zone on the FIRM included in the FIS prepared by FEMA for which base flood elevations have been provided.
(1) 
The AE Area adjacent to the floodway shall be those areas identified as an AE Zone on the FIRM included in the FIS prepared by FEMA for which base flood elevations have been provided and a floodway has been delineated.
(2) 
The AE Area without floodway shall be those areas identified as an AE Zone on the FIRM included in the FIS prepared by FEMA for which base flood elevations have been provided but no floodway has been determined.
(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.
(b) 
No new construction or development shall be located within the area measured 50 feet landward from the top-of-bank of any watercourse, unless the appropriate permit is obtained from the Department of Environmental Protection Regional Office.
C. 
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 base 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. The Borough of Doylestown 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. 
The AO and AH Area/District shall be those areas identified as Zones AO and AH on the FIRM and in the FIS. These areas are subject to inundation by one-percent-annual-chance shallow flooding where average depths are between one and three feet. In Zones AO and AH, drainage paths shall be established to guide floodwaters around and away from structures on slopes.
3. 
Changes in Identification of Area. The identified floodplain area may be revised or modified by the Borough of Doylestown 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. See § 1205.1B for situations where FEMA notification is required.
4. 
Boundary Disputes. Should a dispute concerning any identified floodplain boundary arise, an initial determination shall be made by the Borough of Doylestown, and any party aggrieved by this decision or determination may appeal to the Council. The burden of proof shall be on the appellant.
5. 
Jurisdictional Boundary Changes. Prior to development occurring in areas where annexation or other corporate boundary changes are proposed or have occurred, the community shall review flood hazard data affecting the lands subject to boundary changes. The community shall adopt and enforce floodplain regulations in areas subject to annexation or corporate boundary changes which meet or exceed those in 44 CFR 60.3.
[Ord. 2015-5, 3/16/2015]
1. 
General.
A. 
Alteration or Relocation of Watercourse.

No encroachment, alteration, or improvement of any kind shall be made to any watercourse until all adjacent municipalities which may be affected by such action have been notified by the municipality, and until all required permits or approvals have first been obtained from the Department of Environmental Protection Regional Office.
(2) 
No encroachment, alteration, or improvement of any kind shall be made to any watercourse unless it can be shown that the activity will not reduce or impede the flood-carrying capacity of the watercourse in any way.
(3) 
In addition, FEMA and the Pennsylvania Department of Community and Economic Development shall be notified prior to any alteration or relocation of any watercourse.
B. 
When a community proposes to permit the following encroachments: any development that causes a rise in the base flood elevations within the floodway; or any development occurring in Zones A1-30 and Zone AE without a designated floodway which will cause a rise of more than one foot in the base flood elevation; or alteration or relocation of a stream (including but not limited to installing culverts and bridges) the applicant shall (as per 44 CFR 65.12):
(1) 
Apply to FEMA for conditional approval of such action prior to permitting the encroachments to occur.
(2) 
Upon receipt of the Administrator's conditional approval of map change and prior to approving the proposed encroachments, a community shall provide evidence to FEMA of the adoption of floodplain management ordinances incorporating the increased base flood elevations and/or revised floodway reflecting the postproject condition.
(3) 
Upon completion of the proposed encroachments, a community shall provide as-built certifications. FEMA will initiate a final map revision upon receipt of such certifications in accordance with 44 CFR Part 67.
C. 
Any new construction, development, uses or activities allowed within any identified floodplain area shall be undertaken in strict compliance with the provisions contained in this Part and any other applicable codes, ordinances and regulations.
