Motor Fuel Tax Funds

As an Illinois Department of Transportation prequalified firm we have completed communities’ annual Motor Fuel Tax programs.  Municipalities have placed their trust in Trotter and Associates by allowing TAI to not only handle the engineering and financial related duties but also serve as their liaison for resident communication.  Trotter and Associates also works with the community to identify alternate uses for the MFT funds such as;


Storm Sewers and Stormwater Management

Sidewalks and Pedestrian Paths

Salt Storage Facilities

Parking Facilities

Employee Salary and Fringe Benefits

Bicycle Signage

Traffic Control Devices



Pedestrian and Bicycle Facilities

In addition to vehicular related transportation related projects, our staff has experience in bicycle and pedestrian improvements.  While serving as municipal representatives for the Chicago Area Transportation Study (C.A.T.S.) and local special interest groups our employees aided in the development of regional master plans.


Trotter and Associates recognizes the importance of preserving the character of each community while developing a vehicular, pedestrian safe environment. Our experience working with municipal engineers, planners, police departments, and special interest groups has given us insight on the priorities of each group.  We succeed in working with these stakeholders throughout the course of the project.
