Frequent Issues
Pot Holes and Pavement Repair
With about 2,700 lane miles of roadway to manage, and limited funding for large-scale road improvement projects, pot holes and other forms of damaged pavement are a common occurrence.
Overgrown Vegetation
Transportation & Public Works Road Maintenance crews deal specifically with vegetation management on County roads for the purpose of keeping the roadway unobstructed. Road Maintenance crews do not manage vegetation on private property, or any facility other than County roads. If you spot a section of road, road sign, street light, or other road safety infrastructure obstructed by vegetation, please contact us right away.
Road Sign Maintenance
The County maintains over 18,000 road signs (street name signs, stop signs, speed limit signs, etc.), each of which needs to be periodically cleaned for visibility, and occasionally repaired.
