Cole County explores watershed project near Pioneer Trail School to curb flooding and improve water quality

Consultants and public-works staff told the Cole County Commission on July 7 that a completed watershed-based plan could open state and federal grant funds to address downstream flooding and high nutrient levels in Bender (Binder) Lake.

Ed Galvert of Bar (Barr) Engineering summarized the three-year study that began as ARPA-funded stormwater projects and has identified several candidate sites in the Bender/Binder and Naches watersheds. Galvert said the team documented historical high-flow problems, modeled rainfall and tested concept designs to estimate how projects would reduce flow and velocity downstream.

"It's like a diet plan for pollution," Galvert said, describing the watershed plan's role in defining how much nutrient and sediment reduction is needed and which projects would achieve it. He told commissioners a plan written by the Missouri Department of Natural Resources (DNR) would be required to apply for the available grants.

Why it matters: DNR has listed Bender Lake as impaired for chlorophyll a and elevated phosphorus and nitrogen, which triggers eligibility for targeted water-quality funding. Galvert said the data-driven designation does not necessarily match public perception of the lake, but it creates funding opportunities that local partners can use to implement projects.

What was proposed: The county and school district have identified a largely unused county parcel south of Pioneer Trail School as a possible detention basin and educational amenity. Under the concept, a basin would hold stormwater during large events, reduce downstream flood pressure, remove roughly half of incoming solids and about a quarter of phosphorus at the conceptual site, and include interpretive trails and learning features for students.

Funding and partners: Galvert said DNR agreed to prepare the required watershed-based (nine-element) plan if the county and local partners commit as sponsors. Project grants would generally follow a 60/40 structure (60% external funding, 40% local match in cash or in-kind), he said; actual project costs are "TBD" until the plan and project designs are completed.

Next steps and timeline: Staff said DNR will draft the watershed plan with input from the county, parks and the school district. Once the plan is complete, the county can apply for project funding; staff cautioned this would be a multi-year effort likely to span several grant cycles.

Sources and attribution: The summary incorporates remarks by Ed Galvert (Bar Engineering Company) and staff from Cole County public works, who presented the study and answered commissioners' questions. The commission did not take a formal vote on the concept at the July 7 meeting.

What to watch for: completion of the DNR watershed plan, formal sponsorship agreements among the county, parks and school district, and subsequent grant applications for one or more detention or water-quality projects.
