The City of Kirksville says as you’re mowing this summer, remember to keep grass clippings off the streets and out of the City’s storm drains. Blowing grass and other yard debris onto the sidewalk, street, or stormwater system is a violation of the Municipal Code, and a danger to others. Grass clippings, leaves, and other lawn debris can clog stormwater drains, resulting in flooding, and add unnecessary biological matter to our stormwater system. In addition to environmental harm, you may be creating a safety hazard. When blown into the street, clippings can create a slippery and dangerous surface for traveling motorcyclists and bicyclists.
