87.30 Annotation There is nothing in the Department of Natural Resources’ general grant of authority to regulate floodplains that permits the agency to write rules that nullify the discretion over variance decisions that the legislature has specifically committed to local boards of adjustment. To the extent that a department rule prohibits county boards of adjustment from granting variances from flood elevation requirements when the proper statutory standards for variances have otherwise been met, it is invalid.
