The Lower Miller River Floodplain Restoration Design Project (LMRFRD) will identify a preferred restoration strategy and develop an implementable preliminary plan for restoring the lowermost mile of the Miller River, its floodplain and its confluence with the Skykomish River. The design will seek to maximize habitat value for ESA listed fish: Chinook, coho, pink and steelhead, throughout the roughly 165 acre floodplain and alluvial fan within the project area by removing artificial constraints on fluvial processes. Primary project actions will include removal of approximately 900 feet of Old Cascade Highway west of the Miller River, the Miller River Bridge and a smaller culvert over Spree Creek in the Miller River floodplain. These nonfunctioning structures limit floodplain connection, impair channel migration and impact habitat throughout this important confluence environment. The restoration plan will also include removal of approximately 1000 feet of existing flood control facilities from the left bank floodplain; removal or reconfiguration of up to 400 feet of right bank flood control facilities, invasive plant species removal and plantings, and in channel wood placement. Some actions may be implemented in the future depending on property owner negotiations and/or acquisition success.Funding would support alternatives analysis and preliminary design for salmon conservation in this high priority location in unincorporated King County, WRIA 7.
