What are County Engineers?

County Engineers are licensed professional engineers who oversee the planning, design, construction, and maintenance of public infrastructure within a county, such as roads, bridges, drainage systems, and public buildings.

County Engineers also play a key role in developing long-term infrastructure plans and responding to emergency situations that impact public works. Their work is essential to maintaining safe and efficient transportation and public services for the community.
