Right-of-Way Adjustment Programs

The Maps and Plats Section of CDOT manages several programs that can be used to facilitate changes to the configuration of public streets and alleys.   Pending aldermanic support, successful review, and utility vetting of a proposed project, the resulting assembled parcel can be used for industrial, commerical or residential expansion or development.

Plan Review

The Chicago Department of Transportation (CDOT) is responsible for reviewing development proposals that impact the public right-of-way.  Prior to the legislative approval for Planned Developments, Lakefront Protection Applications and Zoning Board of Appeals, applicants must receive approval from the CDOT Plan Review Committee (PRC).  Additionally over-sized driveways (any curb cut with a driveway greater than 25’ at the property line) will also need CDOT-PRC approval before a driveway permit is issued.
