The DNR has developed maps and information for livestock and poultry producers who are determining where to locate a new animal feeding operation, or who are deciding if they can expand or modify an existing operation.
Iowa laws have specific requirements for building, expanding or modifying open feedlots and confinement feeding operations located in the 100-year floodplain. Knowing if a potential site has
alluvial soils is one step in determining if the site could be in a floodplain and if building restrictions could apply. Depending upon specific site conditions, construction may be prohibited or a floodplain permit may be required. |

All animal feeding operation structures have a "high damage potential," meaning flood protection (both structural integrity and elevation of the lowest opening) must be provided to the level of the 100-year floodplain plus one foot. In addition, the construction must allow for the conveyance of flood flows.
Iowa law also prohibits placing confinement feeding operations within 1,000 feet of a sinkhole, and sets specific separation distances from other protected waters. Animal producers who plan to build, modify or expand a confinement feeding operation structure will need to find out if the proposed location is in
karst terrain. |
