THE LOWEST HABITABLE FLOOR OF ANY RESIDENTIAL STRUCTURE MUST BE AT LEAST ONE FOOT HIGHER THAN THE ELEVATION OF THE OUTER LIMIT OF THE FP DISTRICT. THE ELEVATION OF SAID LOWEST FLOOR SHALL BE PROVIDED ALONG WITH THE REQUIRED SITE PLAN. ANY BASEMENT OR CELLAR OF A RESIDENTIAL STRUCTURE NOT DESIGNED FOR HUMAN HABITATION MAY LIE BELOW THE ELEVATION OF THE OUTER LIMIT OF THE FP DISTRICT, PROVIDED THAT IT IS FLOOD PROOFED IN ACCORDANCE WITH §43D-2C OF THIS ARTICLE AND FURTHER PROVIDE THAT THE LOCATION OF SUCH STRUCTURE DOES NOT ENCROACH UPON THE FLOOD WAY.

ANY NEW STRUCTURE, OTHER THAN A RESIDENTIAL STRUCTURE, TO BE BUILT IN A BUSINESS OR MANUFACTURING ZONE OVERLAPPED BY THE FP DISTRICT OR ANY ADDITION TO AN EXISTING COMMERCIAL OR INDUSTRIAL BUILDING, SHALL BE CONSTRUCTED SO THAT THE LOWEST FLOOR IS AT LEAST ONE FOOT HIGHER THAN THE ELEVATION OF THE OUTER LIMIT OF THE FP DISTRICT, OR SHALL BE FLOOD PROOFED IN ACCORDANCE WITH §43D-2(C) OF THIS ARTICLE, PROVIDED THAT IN NO CASE SHALL SUCH STRUCTURE ENCROACH UPON THE FLOOD WAY. C. IN CASES IN WHICH FLOOD PROOFING MEASURES ARE PERMITTED TO SATISFY THE REQUIREMENTS OF THIS ARTICLE THE PLANNING COMMISSION SHALL SEEK TO INSURE IN THE PROCESS OF SITE PLAN REVIEW THAT SUCH MEASURES WILL BE CONSISTENT WITH FLOOD ELEVATIONS, VELOCITIES AND VOLUMES OF THE INTERMEDIATE REGIONAL FLOOD FOR THE SITE IN QUESTION.
