Where floodproofing by means of elevating on fill is deemed inappropriate or impractical, and where floodproofing by means other than filling is permitted, floodproofing measures shall be in accordance with the following:

1. Floodproofing measures shall be designed to:
   1. Withstand the flood pressures, depths, velocities, uplift and impact forces, and other factors associated with the 100-year recurrence interval flood; and
   2. Assure protection to an elevation at least two (2) feet above the elevation of the 100-year recurrence interval flood; and
   3. Provide anchorage of structures to foundations to resist flotation and lateral movement; and
   4. Insure that the structural walls and floors are watertight and completely dry without human intervention during flooding to a point at least two (2) feet above the elevation of the 100-year recurrence interval flood.
2. No permit or variance shall be issued until the applicant submits a plan or document certified by a registered professional engineer or architect certifying that the floodproofing measures are adequately designed to protect the structure or development to a point at least two (2) feet above the elevation of the 100-year recurrence interval flood for the particular area.
3. Floodproofing measures may include, but are not limited to:
   1. Reinforcement of walls and floors to resist rupture or collapse caused by water pressure or floating debris;
   2. Addition of mass or weight to structures to prevent floatation;
   3. Placement of essential utilities above the flood protection elevation;
   4. Surface or subsurface drainage systems, including pumping facilities, to relieve external foundation wall and basement floor pressures;
   5. Construction of water supply systems, and waste treatment and collection systems to prevent the infiltration of floodwaters into such systems;
   6. Cutoff valves on sewer lines and the elimination of gravity flow basement drains; and/or
   7. The construction of permanent or moveable watertight bulkheads, erection of permanent watertight shutters and doors, and installation of wire reinforced glass or glass block for windows.
4. CERTIFICATE OF COMPLIANCE. (Am. #3-04) No vacant land in the floodplain, and no building hereafter erected, altered or moved into the floodplain, may be occupied or used until the applicant obtains a certificate of compliance from the City. The certificate may be issued only after the applicant has submitted, prior to occupancy, to the Zoning Administrator a certification by a registered professional engineer or architect that the floodproofing requirements in the zoning ordinance have been met and a certification by a registered professional engineer, architect or registered land surveyor that the following are in compliance with the zoning ordinance.
