Street Sweeping Buffalo Grove attempts to sweep every street once per month. This is to provide attractive streets and help prevent flooding. We do our best to remove debris in a professional and cost effective manner. You have questions, we have answers! WHAT IS THE PROCESS FOR SWEEPING STREETS? The Village is divided into ten sections. Sweepers start in Cook County and end in Lake County. Two sweepers are deployed to effectively sweep all streets. HOW OFTEN ARE STREETS SWEPT? During the spring and fall months, the entire village is swept on a monthly basis. During the summer and winter months, the village is swept as needed. DOES STREET SWEEPING COLLECT LEAVES FROM MY YARD? WHY NOT? Village sweepers are not designed to collect leaves from yards. Raking leaves into the street is a violation of Village code because this can cause a slow down in cleaning as well as increase flooding chances.
