The staff at DHA has a long history of working on transportation planning projects, both on the state highway system and for local streets and roads. The principals of DHA have worked at Caltrans, and understand the project development process, especially from a funding and project initiation perspective. The key to success with planning projects is to initiate and maintain communication with the appropriate decision makers at the oversight and funding agencies. From their offices in Sacramento, DHA maintains regular contact with critical decision makers at the Caltrans and FHWA headquarters offices.
