COVID-19 Notice

As our state continues to experience the effects of the COVID-19 outbreak, Grant County Public Works will be taking the necessary measures by following the recommendations from local, state, and federal officials in regard to social distancing.


All Grant County Public Works offices are open.

Employees will still be reporting to work and continuing their day-to-day job duties. We have installed a “Drive-Up Drop Box” located in front of our Public Works Administration building. This will allow the public to drop off permits, plans, and plats.

To protect our community and staff we encourage communication by phone, email, and appointments.


Effective immediately, we will not be scheduling the Public Meeting room for use. Per Proclamation 20-14: Reduction of Statewide limits on gatherings. If your agency or non-profit organization has a Public Meeting room scheduled, our office will be contacting you. We will revisit scheduling as new recommendations become available.


The Public Works Department's primary responsibility is to maintain the County Road system by:

  • Asphalt Overlays

  • Oversize and overweight motor vehicle permits
  • Permits for access to County roads and culvert placement
