Consistent with the rest of New England and other counties in the state of Vermont, the county has little formal county government. There are a few agencies that serve county-wide. One is the Chittenden County Solid Waste District.
In 2008, the Solid Waste District announced that it would charge trash haulers $17/ton for recyclables. Formerly it was paying $7/ton. The global economy has reduced the demand for recycled materials. 
Interstate 89 crosses Chittenden County initially from east to west, then makes a northward turn in South Burlington to run north along the Lake Champlain shoreline. The full trajectory is generally from southeast to northwest. There are seven interchanges within the county. Four of the interchanges provide direct access to U.S. Route 2, which parallels the interstate throughout most of the county. U.S. Route 7, the county's main north-south surface route, is also directly accessible from two interchanges.
The Chittenden County Metropolitan Planning Organization measures traffic, analyzes road conditions, and allocates federal and state funds accordingly. 
There is a private, amateur Champlain Valley Swim League with nine members, mostly from Chittenden. 
In Vermont, gores and grants are unincorporated portions of a county which are not part of any town and have limited self-government (if any, as many are uninhabited).
