The Yakama Nation (YN), is soliciting a Request for Proposals for Engineering Design Services for two road crossings in the White Creek Watershed, within the Closed Area of the Yakima Nation Reservation in south central Washington State. The crossings are located on the 175 Road over Brush Creek and on the 191 Road over White Creek. Crossings will be designed to provide year round passage for aquatic species and longitudinal movement of flood flows, wood and sediment. The goal is to obtain designs at the 60% level by March 2021.
Brush Creek is a tributary to White Creek, and both watersheds are located within the Closed Area of the Yakama Reservation, approximately 20 miles east of Mount Adams. White Creek flows into the Klickitat River at river mile 40. The White Creek sub-basin provides critical spawning and rearing habitat for ESA-listed Middle Columbia River steelhead and is a focal area for salmonid restoration efforts. Recent fisheries studies indicate that White Creek accounts for an average of 13 percent of the annual observed spawning in the Klickitat River Basin, although percentages as high as 31 percent have been noted (Yakama Nation Fisheries Program).
Ongoing efforts to improve aquatic habitat conditions for ESA listed O. mykiss have focused on improving passage at major road crossings, restoring incised meadows and disconnected sections of headwater streams, and replenishing in-channel wood throughout the White Creek watershed.

Questions regarding Cedar Valley Road RFP
Question 1: Will there be an opportunity to visit the sites prior to the proposal being due? We understand the sites are within the Closed Area but we may want to visit them if we are able to put together a better scope/cost estimate.
Response 1: At this point, an in-person visit will not be possible. The Reservation remains closed and Tribal leadership is taking precautions related to COVID-19. We are committed to providing as much information as possible remotely. It may be possible to obtain specific measurements as needed. Please let me know if you have a request.
Question 2: Does the road(s) need to remain open/passable during construction?
Response 2: These roads do not need to remain open during construction. There are alternative routes that may be used.
Question 3: Will Yakama Nation be providing wetland/waters delineation to support identification of constraints?
Response 3: Yakama Nation Fisheries staff will take the lead on wetlands related identification of constraints and permitting requirements.
Question 4: How many personnel will be available to support the topographic survey?
Response 4: Two, possibly three staff can assist
