Burke (julieburke@ctuir.org) 541-429-7292 (Office & Fax) Request for Clarification Deadline: February 2, 2024 - 4:00 pm PST Project Purpose and Location The Confederated Tribes of the Umatilla Indian Reservation (CTUIR), Department of Natural Resources Fisheries Program is currently requesting proposals for floodplain reconnection and in-stream fish habitat enhancement design and construction oversight within the Walla Walla River at River Mile 32.5 near the historic Frenchtown site (Attachment A). The location of the project site is 11 miles west of Walla Walla. The implementation of this project will improve in-stream habitat for Endangered Species Act (ESA)-listed and non-ESA-listed native fish species, while benefiting natural channel morphology and in-stream processes. The products from this restoration effort should improve all 5 River Vision Touchstones (Jones et al. 2008): o Water quality and quantity - increase base flow through functional connection with the alluvial aquifer, decrease summer stream temperatures; o Geomorphology - restore natural form, sinuosity, complexity, geomorphic stability of channel, enhance large wood and boulders to increase channel complexity, improve sediment routing/dispersal; o Connectivity - increase lateral connection with the historic floodplain, vertical connection with the alluvial aquifer, and provide year-round passage for all life stages of salmonids at irrigation diversions; o Riparian Vegetation - protect existing riparian vegetation and enhance to improve geomorphic function and water quality; and, o Aquatic Biota - increase the quality, quantity, and diversity of habitat for resident and anadromous fish of all age classes. The Project will likely consist of a combination of in-stream and floodplain actions to enhance fish habitat and riparian resources on the Walla Walla River. Design elements may include levee removal, floodplain excavation, installation of wood and rock habitat structures, creation of side channels, improvements to irrigation intakes, and riparian and upland planting along approximately 0.5 mile of the mainstem Walla Walla River. The primary objective of the project is to enhance habitat for native fish and wildlife by enhancing ecosystem function throughout the site. Scope of the RFP This Request for Proposals ("RFP") provides the specific services to be contracted as well as information concerning the preparation and submittal of proposals, an explanation of how proposals will be evaluated, and terms and conditions of the contract that may be awarded as a result of the RFP. The products from this contract should include development of a complete design surface for the Walla Walla River Forks project area including channel profiles and ground based topographic survey data integrated with available LiDAR capable of supporting a design for construction. The design must be process-based and consider all restoration possibilities within the floodplain and active channel given existing on-site hydrologic, geomorphologic, and land management constraints with respect to watershed influence. The contractor shall include specification drawings, schematics, detailed project design and representations of expected changes in habitat available to summer steelhead/rainbow trout, bull trout and Chinook salmon. The contractor will be expected to review, analyze and incorporate existing data and collect other data as necessary for describing and predicting specific hydrologic conditions related to floodplain connectivity, water quality, channel morphology, aquatic habitat, and riparian and upland vegetation. The contractor will be expected to collect and analyze the data necessary for describing and predicting changes to the project area before and after restoration as well as a wetland determination. This includes, but is not limited to, specific hydrologic conditions and channel function within the watershed and project area related to floodplain connectivity, water temperature, channel morphology, aquatic habitat, and riparian and upland vegetation. Proper assessment of existing and historical site conditions needs to be adequately described by the contractor to help inform the planning team in their decision making. This includes hard and digital copies of specification drawings, schematics, detailed project design and representations of expected changes in physical floodplain and channel improvements and water quality as well as ecological benefits to habitat suitability for steelhead, bull trout and Chinook salmon. The completed product is to include an itemized cost for the design firm's involvement during construction for construction oversight during 2025, including but not limited to private landowner meetings, development of documents for permitting, technical review and input, environmental compliance, project monitoring plans, construction and project sequencing, and implementation compliance to ensure work is completed as outlined in the final design. The construction contract for implementation efforts will be led by the CTUIR. The Contractor will provide an estimated cost of construction and associated quantities necessary for permitting for the Walla Walla River RM 32.5 Project design and proposed construction in 2025. Project Timeline: The Project is planned to begin April 1, 2024. The project design and costs for construction oversight will be completed or identified by March 31, 2025 with all in stream implementation for the Walla Walla River Forks Project occurring during the July 1 - September 30, 2025 in-stream work window. Responses to questions will be provided no later than February 12, 2024, 4:00 pm PST. Tour of Site A tour of the site will be provided on February 5, 2024, at 1:00 pm. Interested contractors should meet in Walla Walla, Washington at the Frenchtown Monument, 8364 Old Hwy 12, Walla Walla, WA 99362. Attendees should RSVP attendance to the technical and administrative contacts listed on the cover page 5 calendar days prior to the tour date.
