The Department of Public Works covers the county's planning, engineering, flood control, sanitation, storm water, and animal services needs. Every spring the department has an open house during which families can tour the facilities to learn how traffic signals work, how signs are made, how noxious weeds are controlled, how our drinking water is tested and kept safe, how bees are controlled, and get up close and maybe even climb inside of some of those cool vehicles children love to watch - street sweepers, garbage trucks, snow plows, etc.
