Corps studying levee and causeway options for Missouri River bridal access; report due early summer
Summary
Officials said the U.S. Army Corps of Engineers is evaluating options—removing land from the floodplain or building a causeway—with an early‑summer report expected on flood impacts and potential costs.
Committee members heard March 31 that the U.S. Army Corps of Engineers is making "good progress" on a flood mitigation study for Missouri River bridal access and expects results by early summer.
Ray Frankenberg, identified as a flood plain manager, told the committee the corps is examining two primary options: "keeping the river out completely," which would remove land from the floodplain, or building a causeway that raises the road while allowing the river to retain adjacent land. He said the report should identify flood‑elevation impacts for different levee or causeway alignments and may include cost estimates.
Why it matters: The study will inform whether the area can be developed for industrial parks or require other mitigation; river bottom land is often used for industrial development when flood protection costs are addressed.
Details: Frankenberg said the corps might not include income projections for development should land be pulled out of the floodplain; the committee may need to pursue local studies to estimate future land use and revenue if stakeholders want to build industrial parks on former river bottoms.
Next steps: The committee expects to receive the corps report in early summer and will review flood‑elevation impacts, causeway versus full exclusion options, and any cost estimates included in the study.
Ending: Members urged staff to stay engaged and watch for the report, which will guide local planning for flood mitigation and potential development.
