The design for Site 2 consists of a Culvert structure providing for the safe passage of the Mountain Lions. During fall semester the Culvert Design Team established the location of the new Culvert through topographic and geological analysis. The location of the new Culvert is approximately 50 feet south of the existing Culvert (Lat: 33.455865, Lon:-117.136220). The criteria applied in selecting the location was determine due to its friendly terrain and natural canyons. The Culvert was designed using a design criteria the team created that catered to the purpose and needs for the Wildlife Crossing. In the design of the Culvert the elements applied were: openness ratio, Caltrans standards, noise reduction, and lighting. The openness ratio was modified to incorporate the innovative design element proposed by the team of adding an opening to the center median of the freeway. This would increase the amount of light exposure for the Mountain Lions to see through the structure. The design of the center median opening was based off of Velux Sun Tunnels that are used for industrial facilities and residential homes to provide natural lighting. Noise was another main component that was addressed which would be mitigated through the design of sound walls, rubber asphalt, and dense vegetation. After the workshop on November, the design of the Culvert was modified with the feedback from the experts. The Culvert is an arch shape for more stability and more structurally sound. A design for an earth  berm instead of building a sound wall to mitigate the noise levels in the area as well as using geogrid for the bedding of the Culvert was applied.
