Lancaster Mobley was the on-call traffic engineer for the City of Tigard. As such, we were asked to secure ODOT’s approval of a traffic signal at the intersection of Hall Blvd. and Pfaffle St.

The technical memorandum addressed the City’s Transportation System Plan (TSP) and Capital Improvement Plan (CIP) that were related to the study intersection, sight distance analysis, crash data analysis, traffic signal warrants, and design considerations.
