Appendix G - Wildlife Crossings Design for I-15

Type: report

Year: 2018

Purpose: The main purpose of the Wildlife Crossing Design for I-15 was to find engineering solutions to promote mountain lion crossing utilizing the information provided by the biologists. The project was led by three civil engineering advisors at California Polytechnic State University, Pomona and a group of 16 civil engineering students. For the purpose of analyzing a wider range of options for solutions, the students were divided into three teams. The first team consisted of eight students that were tasked with analyzing the site to find the best location for the construction of an overpass and to design the most feasible wildlife bridge design. The second team, a group of four students, were similarly tasked with analyzing the site to find the best fit location and to design a feasible wildlife crossings culvert. And lastly, a group of four students were assigned with producing plans for improving the existing Temecula Creek Underpass. This paper will include the processes for which the locations of each passageway had been chosen, the processes for designing each passageway, and the final designs.
