(f) Prior to construction of any structure on a parcel or lot upon which a floodway easement, floodplain and drainageway exists, the permittee must obtain from the City, a copy of the approved plans showing the location and design elevations of that floodway, floodplain and drainageway. Upon completion of the structure and prior to the issuance of an occupancy permit, the permittee must provide a certification from a registered land surveyor that the floodway, floodplain and drainageway grades and dimensions are as designed. If the floodway, floodplain and drainageway does not conform to the approved plans, the floodway, floodplain and drainageway must be reconstructed and certified prior to the issuance of an occupancy permit for that lot or parcel. Concurrent floodway, floodplain and drainageway reconstruction and issuance of an occupancy permit are permitted only if that action does not present a danger to the safety and welfare of any affected property. To permit concurrent action, the permittee shall provide the City with a performance bond, a letter of credit, or a cash deposit to cover the cost of said reconstruction at a dollar amount established by the City.
