Subdivision and development proposals will be reviewed to determine whether such proposals will be reasonably safe from flooding. If a proposed subdivision or development project is in a flood-prone area, defined as the 100-year floodplain as established by the Federal Emergency Management Agency (FEMA):
A. Such proposal will be reviewed to assure that:
1. It is consistent with the need to minimize flood damage within the flood prone area.
2. All public utilities and facilities, such as sewer, gas, electrical and water systems are located and constructed to minimize or eliminate flood damage, and
3. Adequate drainage is provided to reduce exposure to flood hazards by insuring, at a minimum, that there shall be no increase in the rate of water runoff from the site. The Planning Board may, at its discretion, require that the rate of runoff be decreased from the condition existing prior to subdivision development.
B. The Board shall require that the following provisions apply to subdivisions within the 100-year floodplain:
1. Future-condition storm water runoff discharge does not exceed present condition discharges into a floodway as calculated up to a 25-year frequency storm.
2. Development be prohibited within the floodway which will result in any increase in flood levels during the occurrence of a 25-year frequency storm discharge.
3. That there is no reduction in the holding capacity of the 100-year flood plain.
4. All construction of drainage and flood protection systems and all development within areas subject to flooding are adequately designed so as to accommodate flows resulting from up to a 25-year frequency storm.
5. Every lot be located so as to provide an area for construction of a residential building which is not within a riverine floodway.
