Kirkwood Mountain Resort Culvert Placement and Stream Restoration

Kirkwood Mountain Resort Culvert Placement and Stream Restoration

The California Department of Fish and Game is executing a Lake and Streambed Alteration Agreement number 1600-2007-0089-R2 pursuant to Section 1602 of the Fish and Game Code to the project applicant, Kirkwood Mountain Resort LLC. Stream alterations for construction of the following developments: Palisades Phases 5 and 6; Timbercreek Village - Sentinel Way; and Kirkwood Creek streamzone restoration work as follows: Install one permanent crossing structure for each roadway that intersects a streamzone in the above-listed development area. Roadway crossings will be as specified in plans submitted with the notification package. In addition, the project may have pedestrian crossing structures for each pedestrian pathway intersecting a streamzone not to exceed 10 linear feet of stream channel coverage each. Each crossing should be a bridge, but a culvert is allowable of its diameter and installation do not impede flows (too high or too low). A roadway and pedestrian crossing may be adjacent to each other. In addition, Palisades Phases 5 and 6 will have 15 linear feet of riprap installed at Olympic Court, to capture slope sheet flow and direct flows into the existing tributary. Sentinel Way: Construct one 20-foot by approximately 20-foot riprap outfall for an existing culvert located under Kirkwood Meadow Drive. Stormwater effluent from culvert shall discharge into an area providing infiltration capability to avoid direct water quality impacts to Kirkwood Creek. Kirkwood Creek restoration: 700 linear feet of actively eroding stream bank along three reaches will be stabilized using either local, native stream vegetation, or a combination of hardscaping and vegetation. In addition 60 linear feet of temporarily impacted streamzone will be restored to original ecological functions and values post-project.
