(Beaver Dam) The Beaver Dam Department of Public Works is reminding residents and contractors that it is a violation of city ordinance to discharge grass clippings onto public streets. DPW Supervisor Dan Mulhern says the DNR mandates clean gutters because leaves and grass clippings contribute to the degradation of waterways and ultimately the lake. As the lawn debris decomposes, it affects water quality and also clogs storm pipes, which leads to flooding. When mowing near the roadway, Mulhern says you should direct the chute of the mower away from the road, containing clippings on the lawn. If clippings accidentally end up in the gutter, he says they should be swept up and disposed of. If the city has to clean-up the clippings, it will cost the property owner a minimum of $50. Yard waste can be brought to the Department of Public Works during business hours, Monday through Friday 7am to 3:30pm and now on Saturdays 10am to 2pm.
