Public Works

The Public Works Department is committed to providing quality service to the community by building, maintaining and overseeing a growing infrastructure. Our success will be measured by our spirit of teamwork, responsible stewardship of the environment, pride in our work and enjoyment of our contributions.

We manage, maintain and operate public facilities and public rights-of-way. Our primary responsibilities include engineering, streets, storm drains, street lights, traffic signals and signage.
