Newtown Township City Zoning Code
ARTICLE XXB
Flood Hazard District
[Added 9-9-2002 by Ord. No. 2002-6; amended 2-8-2010 by Ord. No. 2010-01; 10-15-2013 by Ord. No. 2013-08; 9-2-2015 by Ord. No. 2015-03]
§ 172-100.12 Findings.
A.
The Legislature of the Commonwealth of Pennsylvania has, by the passage of the Pennsylvania Flood Plain Management Act of 1978, delegated the responsibility to local governmental units to adopt floodplain management regulations to promote public health, safety, and the general welfare of its citizenry.
B.
Certain areas of Newtown Township are floodplain areas subject to periodic flooding from watercourses or inadequate drainage, wet soils or soils having a high-water table, which flooding results in loss of property, danger to life, damage to structures, injury to people, disruption of public and private activities and services, burdensome public expenditures for flood protection and relief, and impairment of the tax base, all of which adversely affect the public health, safety, and general welfare.
C.
Flood losses are caused by the cumulative effect of obstructions in floodplain areas causing increases in flood heights and velocities and the occupancy of floodplain areas by uses vulnerable to floods.
D.
Certain sections of Newtown Township are aquifer recharge areas which form the source of the underground water supply and are especially sensitive to pollution and contamination from inappropriate surface uses.
E.
Drainage areas, wet soils or soils having a high-water table and water courses located in Newtown Township are part of integrated drainage basins and as such, the construction or other alteration of land within the Township that increases runoff also increases the flood hazard to communities downstream.
§ 172-100.13 Intent.
A.
It is the purpose of this article to promote the public health, safety and general welfare and to minimize flood losses.
B.
The specific intent of this article is:
(1)
To promote the general health, safety, and welfare of the community.
(2)
To regulate or prevent the erection of buildings and other structures in areas unfit for development by reason of periodic flooding, unsanitary drainage conditions and related hazards.
(3)
To protect public health and the environment by preventing pollution of surface and subsurface water supplies and providing surface area to absorb water for maintenance of the subsurface water supply.
(4)
To protect public safety by managing the use of natural floodplains and valley flats which are subject to periodic flooding.
(5)
To prevent the increase in flood volume and rate of flow which results from covering floodplains with impervious surfaces and from impeding natural drainage channels.
(6)
To provide areas for the deposition of sediment.
(7)
To prevent added downstream damage from increased flood volume and rate of flow and to permit uses of the floodplain compatible with the preservation of natural conditions and the maintenance of the stream flow throughout the year.
(8)
To minimize the financial burden imposed on individuals, businesses, governmental units, and the public in general.
(9)
To promote responsible floodproofing measures within the Floodplain Management District.
(10)
To encourage the utilization of appropriate construction practices in order to prevent or minimize flood damage in the future.
(11)
To comply with federal and state floodplain management requirements.
C.
Designation of Floodplain Administrator. The Zoning Officer of the Township of Newtown is hereby designated and may be referred to herein as the Floodplain Administrator. The Assistant Township Manager, or other individual assigned in writing by the Floodplain Administrator, shall be the Alternate Floodplain Administrator and shall have all powers and responsibilities as the Floodplain Administrator when serving in that capacity.
§ 172-100.14 Establishment and identification of district.
A.
Overlay district.
(1)
The Floodplain Management District (FMD), also referred to herein as "Floodplain District", as defined and described by this article shall be deemed an overlay district where applicable on any zoning district now or hereafter delineated on the Township Zoning Map.
(2)
Should the Floodplain Management District be declared inapplicable to any parcel of land by reason of action by the Zoning Officer, the Zoning Hearing Board, or any court of competent jurisdiction, the zoning applicable to such parcel shall be deemed to be the underlying district in which the parcel is located, without consideration of the Floodplain Management District.
(3)
Should the zoning of any parcel or any part thereof over which the Floodplain Management District is located be changed through any legislative or administrative actions or judicial discretion, such change shall have no effect on the Floodplain Management District unless such change was made with respect to the Floodplain Management District.
(4)
It shall be unlawful for any person, partnership, business or corporation to undertake, or cause to be undertaken, any construction or development anywhere within Newtown Township unless the proposed work has been reviewed for compliance with the provisions of this article by the Zoning Officer and a permit issued.
(5)
A compliance review shall not be required for minor repairs to existing buildings or structures.
B.
Establishment of boundaries. The Floodplain Management District is defined and established as those areas of the Township subject to flooding as defined in the following enumerated subsections, with the most extensive of those areas described in the following subsections determining the outermost boundary of the Floodplain Management District:
(1)
All lands designated by the soil map symbols and mapping unit names shown on maps contained in the Soil Survey Report of Chester and Delaware Counties issued by the Soil Conservation Service (i.e., the Natural Resources Conservation Service (NRCS)) United States Department of Agriculture, dated May 1963 or later revision, as follows:
Map Symbol | Mapping Unit Name |
|---|---|
We | Wehadkee silt loam |
Ch | Chewacla silt loam |
WoA, WoB, WoC | Worsham silt loam |
(2)
All areas which have flooded within the last 100 years, as recorded or indicated by written or other objective records, such as surveys by the United States Army Corps of Engineers.
(3)
All areas which, by hydrological stream profile analysis conducted by a registered professional engineer or geologist are calculated to be inundated during a nominal one-hundred-year-frequency flood. Such analysis shall be required prior to the issuance of any permits if, after consultation with the Township Planning Commission and Township Engineer, the Zoning Officer has reason to believe that the applicant's property, or a portion thereof, is in such close proximity to a floodplain area as to be subject to inundation by a one-hundred-year-frequency flood. If the analysis demonstrates that the property or a portion thereof will not be subject to inundation, such permits as are required shall be considered for approval, but shall not be issued unless and until the applicant has complied with all other applicable provisions of this article and with all other applicable ordinances and regulations.
(4)
All areas of Newtown Township classified as special flood hazard areas (SFHAs) as identified by the Flood Insurance Study (FIS) and the accompanying Flood Insurance Rate Maps (FIRMs) dated November 18, 2009, prepared for the Township and issued by the Federal Emergency Management Agency (FEMA), including all digital data developed as part of the Flood Insurance Study, or most recent revision thereof.
(a)
The above referenced FIS and FIRMs, and any subsequent revisions and amendments are hereby adopted by Newtown Township and declared to be part of this Code.
(b)
These areas shall consist of the following specific areas:
[1]
FW (Floodway area): the areas identified as "floodway" in the AE Area by the FIS and FIRM. The term shall also include floodway areas which have been identified in other available studies or sources of information for those floodplain areas where no floodway has been identified in the FIS.
[2]
FF (flood-fringe area): the remaining portions of the one-hundred-year floodplain in those areas identified as an AE Area with or without identified or delineated floodplain by the FIS and FIRM. The basis for the outermost boundary of this area shall be the one-hundred-year-flood elevations as shown in the flood profiles contained in the FIS.
[3]
FA (general floodplain area): the areas identified as A Area by the FIS and FIRM 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, computation, etc., shall be submitted in sufficient detail to allow a thorough technical review by the Township.
(5)
All areas containing hydric soils as determined by the following hydric soil boundary short procedure:
(a)
A landowner, upon executing an agreement with the Township Board of Supervisors, may submit detailed soil profiles and a report to the Township Engineer for purposes of determining hydric soil classification and the boundary of the Floodplain Management District.
(b)
If the Township Engineer and the landowner agree that the site-specific information supplied by the landowner indicates an accurate classification of the soils, then the Township Board of Supervisors will accept the extent of hydric soil as the boundary of the Floodplain Management District if not in conflict with the floodplain area and the community-identified flood hazard areas.
(6)
All areas of Newtown Township classified as special flood hazard areas (SFHAs).
(7)
Community-identified flood hazard areas, which are those areas where the Township has identified local flood hazard or ponding areas based on historical data and records, or has 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.
(8)
Areas not reflected above, but which may be subject to inundation. These areas shall be identified by field survey and by hydrologic and hydraulic calculation and shall be subject to the review and approval of the Township Engineer, who shall make the determination as to the outermost boundary. Hydrologic and hydraulic analyses shall be undertaken only by professional engineers or geologists, 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 Township.
C.
Boundary revision and disputes.
(1)
Studies used to establish the boundaries of the Floodplain Management District will be available in the Township Municipal Building for reference.
(2)
The boundaries of the Floodplain Management District may be revised or modified by the Board of Supervisors from time to time upon recommendation by the Township Engineer based upon detailed engineering studies or information provided by a qualified agency or person that documents the need for such revision. However, prior to any such change, approval must be obtained from FEMA. Additionally, as soon as practicable, but not later than six months after the date such information becomes available, the Township will notify FEMA of the changes by submitting technical or scientific data.
(3)
Whenever there is a difference between any map setting forth the Floodplain Management District or a portion thereof and the data contained in the studies, the data contained in the studies shall determine the boundary of the Floodplain Management District.
(4)
Should a dispute with respect to the boundaries of the Floodplain Management District arise, an initial determination of the boundaries shall be made by the Zoning Officer after review and comment on the boundary dispute by the Township Engineer.
(5)
Any party aggrieved by a decision of the Zoning Officer as to the boundaries of the Floodplain Management District may appeal the decision to the Zoning Hearing Board as provided by this chapter. The burden of proof in such an appeal shall be on the appellant.
(6)
Insofar as various natural conditions, including areas forming the Floodplain Management District, may change, such changes may be determined by detailed on-site survey techniques and hydrologic and hydraulic studies.
(7)
The Zoning Hearing Board shall determine whether a proposed use is within the Floodplain Management District upon appeal from a decision of the Zoning Officer.
(8)
The Zoning Hearing Board may consider the findings of a detailed on-site survey and hydrologic and hydraulic studies presented by the landowner and/or applicant, and other evidence presented by the landowner and/or applicant and other parties recognized by the Zoning Hearing Board who may support or oppose the decision of the Zoning Officer.
(9)
All changes to the boundaries of the Floodplain Management District are subject to the review and approval of the Federal Insurance Administrator.
(10)
An applicant shall pay all fees for processing applications and shall reimburse the Township for all professional fees and costs of reviews and reports prepared in reviewing a dispute of the Floodplain Management District boundary.

(1)
The danger to life and property due to increased flood heights or velocities caused by encroachments. No variance or special exception shall be granted for any construction, development, use or activity within any floodway area that would cause any increase in the one-hundred-year-flood elevation.
(2)
The danger that materials may be swept onto other lands or downstream to the injury of others.
(3)
The proposed water supply and sanitation systems and the ability of these systems to avoid causing disease, contamination and unsanitary conditions.
(4)
The susceptibility of the proposed use to flood damage and the effect of such damage on the owner.
(5)
The availability of alternative locations not subject to flooding for the proposed use.
(6)
The compatibility of the proposed use with existing and foreseeable uses.

§ 172-100.18 Variance conditions.
A.
If compliance with the elevation or floodproofing requirements stated in this article would result in an exceptional hardship for a prospective builder, developer or landowner, the Zoning Hearing Board may, upon request, grant relief from the strict application of the requirement. Relief issued shall conform to the following conditions:
(1)
If granted, a variance shall involve only the least modification necessary to provide relief.
(2)
In granting any variance, the Zoning Hearing Board shall attach reasonable conditions and safeguards necessary to protect the public health, safety, and welfare of the Township.
(3)
Whenever a variance is granted, the Zoning Hearing Board shall notify the applicant in writing that:

The variance may result in increased premium rates for flood insurance.
(b)
The variance may increase risks to life and property.
(4)
In considering any request for a variance, the Zoning Hearing Board shall consider, at a minimum, the following:
(a)
That there is good and sufficient cause for the variance, 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 this chapter 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 this chapter 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 applicant.
[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;
[2]
Nor create nuisances, cause fraud on, or victimize the public, or conflict with any other applicable state or local ordinances and regulations.
