(2) The lowest floor (including basement) will be elevated to at least one and one-half feet above base flood elevation.
(3) The occupants of the structure can remain inside for an indefinite period of time and be safely evacuated at any time during the base flood.
B. Prevent any significant possibility of pollution, increased flood levels or flows, or debris endangering life and property.
3. All hydrologic and hydraulic analyses shall be undertaken only by professional engineers or others of demonstrated qualifications, who shall certify that the technical methods used correctly reflect currently accepted technical concepts. Studies, analyses, computations, etc. shall be submitted in sufficient detail to allow a thorough technical review by the Township of Dover and the Department of Community and Economic Development.
