The specific purpose of these special provisions is:
A. 
To regulate the subdivision and/or development of land within any designated floodplain district to promote the general health, welfare and safety of the community.
B. 
To require that each subdivision lot in a flood-prone area be provided with a safe building site with adequate access and that public facilities that serve such uses be designed and installed to preclude flood at the time of initial construction.
C. 
To protect individuals from buying lands which are unsuitable for use because of flood by prohibiting the improper subdivision and/or development of unprotected lands within the designated floodplain districts.
The provisions of this article shall supersede the provisions of any other article of this chapter or any other ordinance of the Township as the same shall relate to subdivision and/or land development within any floodplain district as established by Chapter 325, Zoning; provided, however, that any other applicable ordinance shall remain in full force and effect to the extent that the provisions thereof are more restrictive than the provisions of this chapter.
The grant of a permit or approval of a plan for any proposed subdivision and/or land development to be located within any designated floodplain district shall not constitute a representation, guarantee or warranty of any kind by the Township or by any official or employee thereof of the practicability or safety of the proposed use and shall create no liability upon the Township, its officials or employees.
In addition to all other information required by this chapter as part of the preliminary plan, the following shall be prepared and submitted by a registered engineer or registered surveyor for any subdivision and/or land development in a floodplain district:
A. 
A map showing the location of the proposed subdivision and/or land development with respect to any designated floodplain district, including information on, but not limited to, the one-hundred-year flood elevations, boundaries of the floodplain districts, proposed lots and sites, fills, flood- or erosion-protective facilities and areas subject to special deed restrictions.
B. 
Where the subdivision and/or land development lies partially or completely within any designated floodplain district or where the subdivision and/or land development borders on a floodplain district, the preliminary plan map shall include detailed information giving the location and elevation of proposed roads, public utilities and building sites. All such maps shall also show contours at intervals of two or five feet, depending upon the slope of the land, and identify accurately the boundaries of the floodplain districts.
In addition to all other information required by this chapter as part of the final plan, the following shall be prepared and submitted by a registered engineer or registered surveyor for any subdivision and/or land development in a floodplain district:
A. 
All information required for the submission of the preliminary plan incorporating any changes requested by the Board of Supervisors.
B. 
A map showing the exact location and elevation of all proposed buildings, structures, roads and public utilities to be constructed within any designated floodplain district. All such maps shall show contours at intervals of two feet and identify accurately the boundaries of the flood-prone areas.
C. 
Submission of the final plan shall also be accompanied by all required permits and related documentation from the Department of Environmental Protection and any other commonwealth agency or a local municipality where any alteration or relocation of a stream or watercourse is proposed. In addition, documentation shall be submitted indicating that all affected municipalities have been notified of the proposed alteration or relocation. The Department of Community and Economic Development and the Federal Insurance Administration shall also be notified whenever any such activity is proposed.
A. 
General.
(1) 
Where not prohibited by this or any other laws or ordinances, land located in any designated floodplain district may be platted for development with the provision that the developer construct all buildings and structures to preclude flood damage in accordance with this or any other laws and ordinances regulating such development.
(2) 
Building sites for residences or any other type of dwelling or accommodation shall not be permitted in any floodway area. Sites for these uses may be permitted outside the floodway area if the sites or dwelling units are elevated up to the regulatory flood elevation. If fill is used to raise the elevation of a site, the fill area shall extend out laterally for a distance of at least 15 feet beyond the limits of the proposed structures.
(3) 
Building sites for structures or buildings other than for residential uses shall also not be permitted in any floodway area. Also such sites for structures or buildings outside the floodway shall be protected as provided in Subsection A(2) above. However, the Board of Supervisors may allow the subdivision and/or development of areas or sites for commercial and industrial uses at an elevation below the regulatory flood elevation if the developer otherwise protects the area to that height or assures that the buildings or structures will be floodproofed at least up to that height.
(4) 
If the Board of Supervisors determines that only a part of a proposed plat can be safely developed, it shall limit development to that part and shall require that development proceed consistent with this determination.
(5) 
When a developer does not intend to develop the plat himself and the Board of Supervisors determines that additional controls are required to ensure safe development, it may require the developer to impose appropriate deed restrictions on the land. Such deed restrictions shall be inserted in every deed and noted on every recorded plat.
B. 
Excavation and grading. Where any excavation or grading is proposed or where any existing trees, shrubs or other vegetative cover will be removed, the developer shall consult the County Conservation District representative concerning plans for erosion and sediment control and also to obtain a report on the soil characteristics of the site so that determination can be made as to the type and degree of development the site may accommodate. Before undertaking any excavation or grading, the developer shall obtain a grading and excavation permit if such is required by the Township.
C. 
Drainage facilities. Storm drainage facilities shall be designed to convey the flow of surface waters without damage to persons or property. The system shall ensure drainage at all points along streets and provide positive drainage away from buildings, and on-site waste disposal site plans shall be subject to the approval of the Board of Supervisors. The Board of Supervisors may require a primarily underground system to accommodate frequent floods and a secondary surface system to accommodate larger, less frequent floods. Draining plans shall be consistent with local and regional drainage plans. The facilities shall be designed to prevent the discharge of excess runoff onto adjacent properties.
D. 
Streets. The finished elevation of proposed streets shall not be more than one foot below the regulatory flood elevation. The Board of Supervisors may require, where necessary, profiles and elevations of streets to determine compliance with the requirement. Drainage openings shall be sufficient to discharge flood flows without unduly increasing flood heights.
E. 
Sewer facilities. All sanitary sewer systems located in any designated floodplain district, whether public or private, shall be floodproofed up to the regulatory flood elevation.
(1) 
The Township Sewage Facilities Enforcement Officer shall prohibit installation of sewage disposal facilities requiring soil absorption systems where such systems will not function due to high groundwater, flooding or unsuitable soil characteristics. The Board of Supervisors may require that the developer note on the face of the plat and in any deed of conveyance that soil absorption fields are prohibited in designated areas.
(2) 
The Board of Supervisors may prescribe adequate methods for waste disposal. If a sanitary sewer system is located on or near the proposed subdivision and/or land development, the Board of Supervisors shall require the developer to provide sewage facilities to connect to this system where practical and shall prescribe the procedures to be followed by the developer in connecting to the system.
F. 
Water facilities. All water systems located in any designated floodplain district, whether public or private, shall be floodproofed up to the regulatory flood elevation. If there is an existing public water supply system on or near the subdivision, the Board of Supervisors shall require the developer to connect to this system where practical and shall prescribe the procedures to be followed by the developer in connecting to the system.
G. 
Other public utilities and facilities. All other public and/or private utilities and facilities, including gas and electric, shall be elevated or floodproofed up to the regulatory flood elevation.
