This study explores current practices in use by transportation agencies for consideration of utilities during the project development process, including where in the process the utility impacts are assessed and relocation decisions made; what policies, regulations, manuals, and guidelines are used; and how design decisions are influenced by utilities. The study includes both above-ground and below-ground utilities. Information was gathered through a literature review, surveys of U.S. state departments of transportation and Canadian provincial transportation agencies, selected interviews, and case studies. James H. Anspach, J.H. Anspach Consulting, Bend, Oregon, collected and synthesized the information and wrote the report. The members of the topic panel are acknowledged on the preceding page. This synthesis is an immediately useful document that records the practices that were acceptable within the limitations of the knowledge available at the time of its preparation. As progress in research and practice continues, new knowledge will be added to that now at hand. (Author/publisher)
