(Beaver Dam) The Beaver Dam Department of Public Works is reminding residents to avoid discharging grass clippings into the street. DPW Supervisor Dan Mulhern says the city is under mandate by the Wisconsin Department of Natural Resources to assist in improving water quality in lakes, streams and drainage ways which city storm sewers dispense. He says grass clippings can not only clog storm drains, which can cause localized flooding, but can also cause degradation of water quality or receiving waters. Citizens are asked when mowing lawns adjacent to the roadway, to direct discharge of lawn mower towards the yard and not into the street. Mulhern says post clean-up of a violation, minimum of $50, may be issued to the property owner if compliance is not meet. He adds those who contract out lawn mowing should notify their servicer of the city requirement.
