Powers Creek Multiuse Bridge Project
NOE - Notice of Exemption
City of Blue Lake
The City is proposing the construction of a multi-use bridge (pedestrian, bicycle,
and equestrian) over Powers Creek. The proposed project will decrease habitat disturbances by creating an elevated path to that which currently exists through Powers Creek. Furthermore, the proposed project will improve public access and safety along Powers Creek by offering a formal crossing between two popular public destinations, the Rodeo Grounds and residences to the north, and the multi-use trail and Business Park to the south. The proposed bridge project has been designed by SHN, the City's consulting engineer. The channel grading proposed in the SHN plans is consistent with the design plans developed by Greenway Partners for the larger Power Creek Fish Habitat Restoration Project (Appendix 4). The City proposes to construct a 9- ft. x 60-ft. concrete foot bridge over Powers Creek. The bridge will consist of pre-cast footings, steel girders, and pre-cast concrete deck panels. Surficial fill will be placed on the interior channel banks to accommodate a total bridge length of 60 ft. The channel slope under the bridge, as well as any fill protruding into the channel, will be protected with rock slope protection (RSP). The proposed bridge
design includes the construction of a 34-ft.-long northern approach and 50-ft.-long southern approach to provide a transition between the proposed bridge and the existing pathways consistent with the Accessibility Requirements provided in the California Building Code.
