County staff: state-funded saturated-buffer projects nearing construction; county to provide administrative support
Summary
Kossuth County staff updated supervisors on several state-funded saturated-buffer projects designed to reduce nutrient runoff. The projects are funded and administered by the Iowa Department of Agriculture and Land Stewardship (IDALS); county staff will assist with bidding oversight and invoice processing.
Kossuth County staff told the board on April 8 that several IDALS-funded water-quality projects—primarily saturated buffers—are advancing toward final design and bidding.
Tyler (county staff) said two projects in the county are moving forward: one northeast of Algona that is near bidding, and a second that is entering final design at an outlet of a drainage tile system. The projects install side-channel perforated lines and buffer areas to slow and divert low flows so soils and channel banks reduce nitrogen before water enters main tile lines.
The county is participating under a 28E agreement with IDALS to provide administrative support—principally bookkeeping, invoice review, and, when appropriate, running the formal bid opening process at a board meeting to maintain proper public records. Staff emphasized these projects are voluntary and funded by state grant dollars; landowners volunteer to host the project on their property. County staff said the projects do not alter high-flow drainage of existing tile systems and are not intended to replace or impair existing district drains.
IDALS engineers and contacts supervising design were named in the update. Tyler said the state agency often lacks full administrative bandwidth and has asked counties to assist with contract and payment flows; payments return to counties after state review so the county is not advanced out-of-pocket funds.
Why this matters: Saturated buffers are a conservation practice intended to reduce nutrient loads entering streams and downstream drinking-water sources. Because the projects are voluntary and state-funded, county involvement centers on administrative oversight rather than underwriting construction costs.
