As required by City Code section 575, the City of Crystal Lake requires the periodic use of private traffic engineering consultants to provide independent, unbiased evaluations of developments where traffic studies are required or deemed necessary by the City Engineer.

As part of the development review process, the City Engineer may determine that a traffic study is needed to evaluate the impact of the development on surrounding traffic. The developer or developer’s representative should contact the City early in the process to discuss the need for a traffic study. Should a traffic study be required, one of the City’s approved traffic engineering consultants must be used.
