Warrant 3: Roadway Modifications

This warrant is met when the proposed development is expected to significantly impact a roadway segment identified for improvement in the local or state Transportation Improvement Program. This warrant is also met when the proposed development includes modifications to the roadway system. Modifications include addition of lanes to accommodate site-generated traffic, addition of exclusive turning lanes, acceleration/ deceleration lanes, median openings, installation of traffic signals and other traffic control devices, etc.

Warrant 4: Special Cases

This warrant is satisfied if the preliminary study reveals that the traffic generated from the proposed development will create safety, operational, or some other traffic problem, as determined by the City/County Engineer or the Indiana Department of Transportation.

Based upon the traffic impact study, improvements shall be required to maintain the current level of service of the adjacent streets/intersections and nearby intersections. Improvements may also be required by the City/County Engineer or the Indiana Department of Transportation to address access requirements, safety, operational or other traffic flow concerns. All such traffic impact improvements are the responsibility of the owner/developer of the property and may be accomplished either solely by the owner/developer or in partnership with a public or private entity. Right-of-way shall be dedicated for existing roadways either in accordance with the Official Thoroughfare Plan or in a width sufficient to encompass all improvements required as a result of the traffic impact study, whichever is greater.
