Working with Local Government

Governor Hickenlooper has issued an Executive Order directing state agencies to take specific steps to enhance relations with local government. Here is how CDOT is complying with the Executive Order.

When promulgating rules, CDOT routinely utilizes a software system developed by the Department of Local Affairs in coordination with the Governor's Office to notify local elected officials of rule making and request input on the rules.
