To authorize the Auburn Ravine floodplain stabilization by placing sub-grade along the 5,500-ft long Ferrari Ranch Rd alignment with a two-lane road with a median, bike lanes, sidewalks, and an off-street, multi-use trail, north of McBean Dr. The project also included the excavations of the south overbank (including additional excavation of the existing pond) between the proposed Oak Tree Lane crossing and the existing McBean Park Dr crossing along the Auburn Ravine to increase flood attenuation and conveyance capacity. Trails for pedestrian use were provided in the open space corridors along the Auburn Ravine. Construction work included grading of the upper flood terrace and installation of rocked inlet/outlet structures between the low flow channel of the Auburn Ravine and the flood terrace; widening the eastern banks of the Auburn Ravine between McBean Park Dr and the Ferrari Ranch Rd/Oak Tree Lane intersection; removal of riparian vegetation and trees (2 Freemont cottonwood, 2 Valley oak, 2 white alders, 3 Oregon ash, 9 Northern CA black walnut, and 10 willow species) from the Auburn Ravine riparian corridor and replaced them with 100 Freemont cottonwood, 48 Valley oak, 101 white alders, 37 Oregon ash, 92 Northern CA black walnut, and 49+ willow species. This project is related to Enforcement Case No. 15554.
