Street crews have started their yearly line striping around the city. The crews do some of the painting during day time hours but mainly work overnight to avoid as much traffic, parked cars, pedestrian traffic as possible. The line striping consists of painting parking stalls on city streets, city-owned parking lots, crosswalks, and all the school routes. All crosswalks and stop bars around the city have reflective glass beads placed into the paint, to help in low light conditions. The line striping is done in accordance with the Manual on Uniform Traffic Control Devices “MUTCD”. The crews start in the downtown district, then 1st Avenue, then work their way out through the remainder of the city. This process usually takes two to three months of summer, depending on the weather.
