To amend the District’s Environmental Resource Permit Information Manual, Part B, Basis of Review (BOR), which is incorporated by reference in Rule 40D-4.091, F.A.C. These amendments are intended to provide permit applicants with the flexibility to meet the conditions for permit issuance and prevent adverse offsite flooding impacts which may occur as a result of the construction and operation of a surface water management system. Additionally, the proposed amendments to the BOR are intended to be consistent with the methods used to establish the 100 year flood elevations in the updated floodplain maps developed for FEMA by the District.
