Streets, Sidewalks and Traffic

Street Maintenance

City staff maintain over 500 miles of streets including snow removal on all City Streets, mechanical and manual street cleaning, mowing of public right-of-ways, and utility service cut repairs. Continued emphasis is given to our street maintenance program, including asphalt overlay and seal coating of improved streets.

Traffic signals are programmed to minimize vehicle delay and emissions. Solar powered school zone display and warning devices are also implemented. Staff oversee neighborhood traffic programs and solutions for traffic calming in residential areas.
