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.
