§ 131-22 Identification of flood-prone areas.

[Amended 5-11-1992 by Ord. No. 715-C]
A. 
For the purposes of this chapter, the areas considered to be flood-prone within the Borough of Monaca shall be those areas identified as being subject to the one-hundred-year flood in the Flood Insurance Study (FIS) prepared for the Borough of Monaca by the Federal Insurance Administration (FIA), dated June 1979, and any revisions thereto.
B. 
A map showing all areas considered to be flood-prone is available for inspection at the Borough of Monaca offices. For the purpose of this chapter, the following nomenclature is used in referring to the various kinds of flood-prone areas:
(1) 
The FW (Floodway Area) is delineated, for purposes of this chapter, using the criteria that a certain area within the floodplain must be capable of carrying the waters of the one-hundred-year flood without increasing the water surface elevation of that flood more than one foot at any point. The areas included in this area are defined in the Floodway Data Table contained in the Flood Insurance Study as prepared by the Department of Housing and Urban Development (HUD) and shown on the accompanying Flood Boundary and Floodway Map (FBFM). Where no floodway has been delineated in the FIS, such information contained in any other available federal, state or other acceptable source should be used.
[Amended 9-10-1996 by Ord. No. 822]
(2) 
The FF (Flood-Fringe Area) shall be that area of the one-hundred-year floodplain not included in the floodway. The basis for the outermost boundary of this area shall be the one-hundred-year flood elevations contained in the flood profile provided in the FIS.
(3) 
FA (General Floodplain Area) shall be the areas identified as "approximate one-hundred-year floodplain" in the Flood Insurance Study prepared by the FIA.

§ 131-23 Determination of elevations.

[Amended 5-11-1992 by Ord. No. 715-C]
The FA (General Floodplain Area) shall be that floodplain area for which no detailed flood elevations or floodway information is provided. Such areas are shown as "Zone A" on the maps accompanying the Flood Insurance Study prepared by the Department of HUD. For these areas, elevation and floodway information from other federal, state or other acceptable source shall be used when available. When such other acceptable information is not available, the 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.

§ 131-24 Revision of flood-prone areas.

A. 
The areas considered to be flood-prone may be revised or modified by the Borough Council where studies or information provided by a qualified agency or person documents the need or possibility for such revision.
B. 
No modification or revision of any area identified as being flood-prone in the Flood Insurance Study prepared by the Federal Insurance Administration shall be made without prior approval from the Federal Insurance Administration.

§ 131-25 Boundary disputes.

Should a dispute arise concerning the identification of any flood-prone area, an initial determination shall be made by the Building Inspector and any aggrieved by such decision may appeal to the Borough Council. The burden of proof shall be on the appellant.

§ 131-26 Prohibited acts.
