David Roachford


David Roachford conducts and reviews traffic impact and parking studies that require analysis of intersections, site access and circulation, and field data collection. He also assists with neighborhood traffic management plans and bicycle and pedestrian safety plans. David is currently conducting transportation and parking studies for a variety of mixed-use developments and commercial centers in downtown Los Angeles, Koreatown, Chinatown, Hollywood, Santa Monica, Irvine, and Santa Clarita. Additionally, he has reviewed traffic studies for the City of Monrovia and shared parking studies for the City of Brea. Some of his more notable projects include studies for the University of Southern California, Bergamot Station Arts Center, Mack Urban South Park, and the Westfield Valencia Town Center. Prior to joining GTC, David interned for the Los Angeles Department of Transportation where he conducted two studies on Los Angeles development review metrics to determine the need for changes to current City standards. One study focused on vehicular volumes to see if developments overestimated their traffic impacts during peak hours, while the second analyzed City parking requirements to quantify the differences between code requirements, specific plans, and the number of spaces proposed by developers. David's senior thesis titled "Gentrification and Displacement in Los Angeles' Rail Transit Neighborhoods" analyzed neighborhoods surrounding Los Angeles County Metropolitan Transportation Authority stations to determine their socioeconomic changes over time. His work was presented at the 2017 Urban Affairs Association Conference in Minneapolis, MN. David graduated from the University of Southern California with a B.S. in Sustainable Planning and minor in Spatial Studies in May 2017.
