Overall this project allowed for the correction of the last two fish passage barrier culverts on Chumstick Creek. Chumstick Creek is a tributary to the Wenatchee River in WRIA 45 in Chelan County Washington. There were two separate project sites included in this proposal. One at river mile (RM) 1.48 referred to as the Alpenview Project Site, and one at RM 0.52 referred to as the Motteler Road Project Site. The original scope included the removal of a culvert and the installation of a new fish passable structure for each project site. CCNRD staff coordinated all necessary site assessments (cultural resources, geotechnical etc.), design development and permit development and submittal for each site. Each project site underwent a number of redesigns in order to meet permit conditions which impacted the cost and timeline of the overall project. For the Alpenview project, it was determined during the initial design development survey work by Waterfall Engineering that the culvert no longer met the criteria as a fish passage barrier. Originally the culvert was assessed as countersunk creating a slope barrier but by the time design was initiated it was identified that some beaver activity below the culvert had created opportunity for sediment to accumulate which sufficiently raised the bed in the channel approach to the culvert such that there was no longer a slope barrier for fish passage. Waterfall Engineering assessed the condition of the culvert and existing size which was deemed in good condition, and therefore recommended an alternative design approach. The alternative design approach called for the install of 3 engineered log jam structures and channel re-grading immediately downstream of the culvert that would act to retain sediment and maintain suitable grade approach to the culvert. This design approach was presented by Chelan County and Waterfall Engineering to USFWS Fisheries Biologist (match funder) and the Fish Barrier Removal Board (FBRB) Biologist who considered the merits of the design. It was presented to the FBRB Board who voted in favor of undertaking this design. The USFWS provided a letter of support in favor of the design as well. Therefore the project was ultimately changed from a culvert replacement to an instream habitat modification. The design advanced to final design stage smoothly and was permitted and ready to go out to construction bids winter 2020. In the fall of 2020, a change in FEMA policy known as the “No Net Rise” precipitated the need for a new floodplain development permit for projects within the regulatory floodway. It was determined that both the Alpenview and Motteler Road projects are in the classified floodway for Chumstick Creek and must meet the requirement of causing no change in Base Flood Elevations at the Q-100 as a result of the project, or else a formal Letter of Map Revision would be required by FEMA and the County. For Alpenview Road project, modifications were required of the design in order to meet this new policy. This required additional bank excavation at each engineered log jam to accommodate bankfull elevations (BFE) at the Q-100 in order n to meet the FEMA no-rise policy. Additionally, Waterfall Engineering and Chelan County had to prepare a technical memo showing the hydraulic modelling results to support the no-net rise. A planting and access plan was developed to minimize bank and riparian disturbance for the project. The change in the design precipitated new permit applications be revised and submitted to the Army Corps of Engineers and the Washington Department of Fish and Wildlife. Due to these constraints, the project required extensions to the timeline to accommodate these significant change. All construction elements as shown on the final designs as well as final planting, was completed in September of 2022. For the Motteler Road project, the original scope called for the replacement of an undersized corrugated pipe arch culvert (10.9ft. span by 6.9 ft. rise) with a bridge. The existing culvert was assessed by Washington Department of Fish and Wildlife as a fish passage barrier due to slope (1.25 % slope barrier). This project will replaced the arch culvert with a fish passage friendly structure which was originally design as a bridge. The project advanced with the bridge designs to final design and permits were submitted in 2020. Similar to the Alpenview project, the change in the FEMA "no-rise" policy, resulted in significant changes to the design at the Motteler Road project. It was determined that some minor changes to the design such as removal of the habitat features was required in order to meet the new policy. The updated designs were submitted to Chelan County Public Works who is the owner of the bridge. Public Works project engineer had multiple design changes and did not accept the hydrology analysis utilized by Waterfall Engineering for the project. After updated hydraulic analysis by Waterfall Engineering a new Q-100 was accepted for the project from public works and the design engineer, though this resulted in design changes that resulted in a shift from a bridge to an inverted 3-sided box culvert would be the new preferred design for Motteler Road. The final project included the removal of the arch culvert and the installation of a 24'x12' concrete box culvert and all associated channel and bank grading in Fall of 2022. However, due to the early onset of snow, final grading, paving and planting was postponed until May-June 2023. Final planting occurred in May 2023 and final grading and paving of the new crossing occurred in June 2023. Since that time, CCNRD has worked to close out the construction contract with the Contractor for the Motteler project, waiting on final L&I release in order to release retainage and final payment to the Contractor. Delays in this process has resulted in additional time extension amendments.
