Land disturbance of one acre or more in Peoria County triggers Illinois EPA's ILR10 construction stormwater permit. The City of Peoria and the county layer local detention and MS4 requirements on top.
Construction that disturbs one acre or more, or a smaller lot inside a larger common plan, needs coverage under Illinois EPA's ILR10 general NPDES permit before ground is broken, filed with a Stormwater Pollution Prevention Plan. Runoff here drains off steep river bluffs and flat, tile-drained farmland toward Kickapoo Creek and the Illinois River, so the City of Peoria, Peoria Heights, Chillicothe, and Peoria County enforce local stormwater and detention standards under their MS4 permits. Post-construction detention basins must be maintained by the property owner, and illicit discharges to the storm sewers are prohibited.
Disturbing an acre without ILR10 coverage draws Illinois EPA enforcement and stop-work orders. Illicit storm-drain discharges and failed detention basins bring local fines until corrected.
