The Department of Environmental Protection amends this rule chapter to implement Section 380.0937, F.S., which modifies the Sea Level Impact Projection (SLIP) study requirements for state-financed construction projects located within areas at risk due to sea level rise, expanding both the geographic area and types of structures to which this requirement applies, as required by Section 380.0937(3), F.S. The Department has also defined a threshold for potentially at-risk structures or infrastructure located in areas at risk due to sea level rise for which replacement cost is not an appropriate metric, as required by Section 380.0937(1)(e)2., F.S. Beginning July 1, 2024, a state-financed constructor may not commence construction of a potentially at-risk structure or infrastructure located within an area at risk due to sea level rise without conducting a SLIP study that meets the requirements established by the Department. These rule amendments will apply only to construction not commenced as of July 1, 2024. The rule amendments will not apply retroactively to projects that commenced before the date the amended rules become effective; however, projects initiated prior to July 1, 2024, will remain subject to the SLIP study requirements and standards established by Section 161.551, F.S.
