The following standards apply within the regulatory floodplain.
(A) Hydraulically equivalent compensatory storage volume will be required for development in a riverine regulatory floodplain and shall be at least equal to the regulatory floodplain flood storage volume displaced. The storage volume displaced below the existing ten-year frequency flood elevation must be replaced below the proposed ten-year frequency flood elevation. The storage volume displaced above the ten-year existing frequency flood elevation must be replaced above the proposed ten-year frequency flood elevation.
(B) Compensatory storage volume for development in a non-riverine regulatory floodplain area that is also adjacent to a lake shall be equal to the storage volume displaced.
(C) Compensatory storage volume requirements for development in a non-riverine regulatory floodplain that is not adjacent to a lake shall be replaced in accordance with the requirements for the loss of depressional storage in § 55.021(F).
(D) Compensatory storage areas shall be designed to drain freely and openly to the channel and shall be located adjacent to the development. This standard does not apply to non-riverine regulatory floodplain.
(E) A recorded covenant running with the land is required to maintain the compensatory storage volume in areas modified to provide compensatory storage volume.
