A floodplain development permit is required before any grading or construction takes place in a flood hazard area. Please contact the County Floodplain Manager before you invest time or money in plans for an improvement to your property or in places for a new structure.
The adopted Story County Floodplain Management Ordinance is located in Chapter 80 of the Story County, Iowa Code of Ordinances.
The Story County Flood Insurance Study contains information flood profiles and additional flooding information that may be needed in the process of applying for a permit.
