This handbook was created to help maintenance workers be aware of safe ways to mow, cut brush and control other vegetation to increase traffic safety. During the growing season, grass, weeds, and brush often limit a driver’s view of approaching vehicles. Likewise, lush vegetation can act as a screen that hides pedestrians and bikers from drivers an

Drainage of streets and highways is a broad subject. It includes water flow in street gutters, the flow of water in roadside ditches, and the flow of water across the pavement. Some ways of maintaining the street or roadway to control the water flows will increase safety and other ways will not. For example, some grates can be very good at draining
