Oaks Bottom Restoration Project

OAKS BOTTOM RESTORATION PROJECT: This is not a solicitation. This Sources Sought Announcement is for the purpose of identifying firms which are capable and interested in offering a proposal for the following project: The Oaks Bottom Wildlife Refuge is a 160-acre park with diverse habitats including an extensive floodplain located along the east bank of the Lower Willamette River at approximately River Mile 16 in southeast Portland, Oregon. The project area is within the 100-year floodplain of the Willamette River, which is within the tidal zone of the Columbia River. The Willamette River merges with the Columbia River approximately 16 miles downstream of the project site. Daily freshwater tidal fluctuations typically range up to 2.5 feet in the project area. Oaks Bottom offers a unique opportunity for a large, natural, tidally influenced floodplain and wetland area to be restored in the heart of the city. The purpose of the proposed action is to restore a more natural tidal hydrologic connection between Oaks Bottom and the Lower Willamette River, improve diverse fish and wildlife habitats, reduce non-native species populations, and provide unhindered fish passage into and out of Oaks Bottom. A number of restoration measures were considered during the plan formulation process undertaken in this Feasibility Study and evaluated based on their potential benefits to fish and wildlife and costs. The recommended restoration plan includes the following elements: - Replacement of the culvert under the railroad berm with a 16-foot by 10-foot culvert, - Removal of the water control structure, - Excavation of tidal slough channels to connect to the reservoir and southern ponds, - Removal of invasive species, - Revegetation with riparian and wetland species along the channels and around the perimeter of the reservoir and southern ponds, and - Placement of two viewing platforms adjacent to the Springwater Trail.
