All subdivision proposals and proposals for other developments governed by these regulations having lands identified as special flood hazard areas in the Flood Insurance Study for the Town of Conway, NH, together with associated Flood Insurance Rate Maps and Flood Boundary and Floodway Maps of the Town of Conway, shall meet the following requirements:

  1. All subdivision proposals and proposals for other developments shall be located and designed to assure that all public utilities and facilities, such as sewer, electrical and water systems, are located and constructed to minimize or eliminate flood damage and adequate drainage is provided to reduce exposure to flood hazards.
  2. Subdivision proposals and other proposed new developments shall include one-hundred-year flood elevation data when any portion of the development is within the floodplain.
  3. In riverine situations, prior to the alteration or relocation of a watercourse, the applicant for such authorization shall notify the New Hampshire Office of State Planning and Wetlands Board and submit copies of such notification to those adjacent communities as determined by the Planning Board. Within the altered or relocated portion of any watercourse, the applicant shall submit to the Planning Board certification provided by a New Hampshire registered professional engineer assuring that the flood-carrying capability of the watercourse has been maintained.
  4. Where new replacement water and sewer systems (including on-site systems) are proposed in flood-prone areas, the applicant shall provide the Planning Board with assurances that new and replacement sanitary sewerage systems are designed to minimize or eliminate infiltration of floodwaters into the systems and discharges from the systems into floodwaters and on-site disposal systems are located to avoid impairment to them or contamination from then during flooding.
