Public Works operates and maintains over 1,035 miles of county roadway and tens of thousands of traffic control system devices. Roadway maintenance includes asphalt repairs often seen during the sunny months, roadway mowing to improve line-of-site for drivers, and drainage system improvements to prevent flooding. Traffic control system maintenance includes installing or fixing traffic signs, street lights, and traffic signals. To ensure safety and the improved traffic conditions, Public Works also performs traffic studies, revises speed limits as necessary, and implements traffic calming in residential neighborhoods.
Please drive safely in construction zones and give crews a brake—they are working to provide you with better and safer roads.

Crews also clean and improve the county roads drainage system during to help prevent flooding later in the year.

Public Works operates 24/7 to provide emergency support during fire, flooding, and icy seasons.
Fire: Watch for road closures in fire prone areas. Do your part to prevent fires. Do not throw burning material from a car window or onto the ground. Don't leave fires unattended.
Flooding: Do not attempt to drive on a flooded street. The water can be deeper or moving faster than you anticipate. Also, it is dangerous and illegal to drive around a “road closed” sign. Fines are greater than $400.
Deicing: Though Public Works crews mitigate icy road conditions by spraying anti-icing solution to roadways, it is still important to slow down and drive carefully to avoid loss of traction and traffic collisions.
Road Priority map: Roads are responded to in a prioritized order, with arterials, major collectors, and routes to emergency locations first. Click here to view the map .
To request speed limit revision in your area, you’ll need to fill out a service request . Staff will then contact you for further detail. The final decision to change a speed limit is set by the Board of County Commissioners. Note: speed limits in school zones and residential areas are set by county code and cannot be changed.
Paint trucks need to drive slowly to get the right amount of paint on our roads. If you are behind a paint truck, DO NOT PASS—you risk getting paint on your car and removing the glass beads that make the paint reflective at night. If the paint looks bright, stay off the lines.
Striping info: May-Sept. +/-1,000 miles a year painted. Main roads once a year, local access roads every 3-4 years.
