Dominican College Master Plan

Dominican College Master Plan

The proposed project is located on Sisters Creek on the campus grounds of Dominican University of California on the 7.5' San Rafael USGS quadrangle map. The applicant proposes to (1) remove and replace an existing pedestrian bridge as well as an existing vehicle bridge, in order to arrest current stream bank erosion and accommodate a higher hydraulic capacity of the channel. Work involves removal of the existing Pedestrian Bridge, creation of a meandering low flow channel and floodplain, grading back the creek bank, construction of new bridge abutments with wing walls, installation of rip-rap under the new bridge and banks, installation of a new larger 18-inch storm drain outlet upstream of the bridge, and installation of a 18-inch storm drain outlet downstream of the bridge with rip-rap to prevent erosion of creek channel. Finally, installation of a new 5' wide by 45' long clear span wood bridge and installation of a rock step in low flow channel. Non-native vegetation and planting of native riparian vegetation will take place as part of the project. (2) Remove an existing vehicular bridge and 48" CMP pipe, create a meandering low flow channel, floodplain, grading back the creek bank, construction of bridge abutments with wing walls, installation of rip-rap under bridge, and installation rock steps in low flow channel. Lastly, installation of a 26' wide by 36' long clear span vehicle bridge and non-native vegetation and planting of native riparian vegetation will take place as part of the project as well. The California Department of Fish and Game is executing a Lake and Streambed Alteration Agreement number 1600-2006-0324-3 pursuant to Section 1602 of the Fish and Game Code to the project applicant, Roger Ono, Dominican University of California.
