1. Purpose and intent.
The flood hazard areas of Schuylkill Township are subject to periodic inundation which would result or has resulted in loss of property and damage to structures, and may result in loss of life, 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 do or may adversely affect the public health, safety and general welfare. Such flood losses are or will be caused by the cumulative effect of obstructions in flood hazard areas which cause increases in flood heights and velocities and the occupancy of flood hazard areas by uses vulnerable to floods. In addition to the general purposes of
§ 370-2: Purpose and the community development objectives expressed in
§ 370-5: Community development objectives of this chapter, it is the purpose of this district to promote the public health, safety, and general welfare and to minimize those losses described above by provisions designed to:
A. Promote the general health, welfare and safety of the public, according to the provisions of Section 604(1) of the Pennsylvania Municipalities Planning Code;
B. Restrict or prohibit uses which are dangerous to the public health or safety, which may damage property in times of flood, or which could cause increased flood heights or velocities;
C. Protect the quality and quantity of surface and subsurface water supplies adjacent to the underlying flood hazard areas;
D. Protect open space along streams, in woodlands and in wetlands and provide areas for the deposition of flood-borne sediment;
E. Require that uses vulnerable to floods, including public facilities, utilize appropriate construction practices in order to prevent or minimize flood damage;
F. Preserve the integrity of stream banks and their immediate vicinity from erosion and the degradation of natural vegetation;
G. Promote the understanding that, where uses are permitted by variance, the land subject to the variance may be designated as lying either totally or partially within the flood hazard area; and
H. Comply with federal and state floodplain management requirements.
2. General provisions.
A. Establishment of Flood Hazard District. The Flood Hazard District, as a minimum, shall include that land adjoining any perennial stream, as shown on the most recent United States Geological Survey quadrangle, or adjoining any ponds or lakes with an area of one acre or more, which is within 50 feet of the banks thereof. The Flood Hazard District shall extend for such additional distance from said banks as is or may be subject to inundation by waters of the one-hundred-year frequency flood. The identified floodplain area shall be those areas of Schuylkill Township, Chester County, which are subject to the one-hundred-year flood, as identified in the Chester County Flood Insurance Study (FIS) dated September 29, 2006, and the accompanying maps (digital and paper) as prepared for by the Federal Emergency Management Agency (FEMA), or the most recent revision thereof. The Flood Hazard Districts shall include the following subdistricts:
(1) FW (Floodway District Area). The areas identified as "floodway" in the AE Zone in the Flood Insurance Study prepared by FEMA and as shown on the accompanying Flood Insurance Rate Maps (FIRM) dated November 20, 1996, or the most recent revisions thereof. 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 Flood Insurance Study.
(2) FF (Flood Fringe District Area). The remaining portions of the one-hundred-year floodplain in those areas identified as an AE Zone in the Flood Insurance Study, 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 in the Flood Profiles contained in the Flood Insurance Study, and as shown on the FIRM maps dated November 20, 1996, or the most recent revisions thereto.
(3) FA (General Floodplain District Area). The areas identified as Zone A in the Flood Insurance Study, and as shown on the FIRM maps dated November 20, 1996, or the most recent revisions thereto, 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 floodway area, if possible. When no other information is available, the one-hundred-year elevations shall be determined by using a point on the boundary of the identified floodplain area which is nearest the construction or development site in question.
