| B | 233447 | 175 | Produce Design | Produce design - passage barrier #4, #5 and #15 | This project will continue floodplain restoration at the Chahalpam Conservation Property, located just west of the town of Stayton, by improving 3 passage barriers and restoring 19 acres of riparian floodplain forest. This Work Element will produce final designs for removal of the 3 passage barriers including sites #4, #5, and #15. This work is separate from, but related to previous BPA contract 88241.
The CTGR has identified the Chahalpam property for restoration activities that primarily include side channel reconnection and reforestation of riparian forest. The CTGR desires to restore floodplain function to the degree possible and this project will continue efforts towards desired future conditions. All 3 passage barriers are identified in the Floodplain Restoration Alternatives Analysis developed by the River Design Group.
Current conditions limit channel connectivity, sediment continuity, fish passage, and floodplain function. Results will include opening one-mile of fish passage comprised of 0.6 mile of Dieckman Tributary and 0.4 mile of its tributary, and restoring native floodplain forest on 19 acres. Conditions will be improved to increase fish passage, flow, and floodplain connection and function. Several native species will benefit including Oregon chub, juvenile Chinook salmon, winter steelhead, and State sensitive species such as Pacific lamprey, western pond turtle, and northern red-legged frog.
River Design Group (RDG) will be selected as a sole source contractor to create the designs. Selection as per following Tribal policy. The conceptual through final designs will be produced with input from a Technical Team that includes BPA COR, and / or other BPA staff. It is expected the design process will start June 2023 and end February 2024. Final designs will be uploaded to CB Fish docs section of this contract. | $12,933 | 5.47% | 06/01/2023 | 05/30/2025 |
| C | 234074 | 85 | Remove/Breach Fish Passage Barrier | Dieckman Creek Tributary Relict Crossing Removal (Site 4) | The Tribe desires to restore floodplain function to the degree possible and this project will continue efforts towards desired future conditions. In 2016, a Floodplain Restoration Alternatives Analysis was developed by River Design Group to identify and prioritize floodplain restoration projects. The document identified 17 project opportunities. In 2021, grant funding was secured from BPA by way of Anchor Habitat Investments (contract 88241) and from OWEB by way of a Restoration Grant (221-3001-18955) to implement two of these projects; implementation occurred in 2022.
This project will continue floodplain restoration at Chahalpam by improving 3 stream crossings and restoring 19 acres of riparian floodplain forest. Current conditions limit channel connectivity, sediment continuity, fish passage, and floodplain function. Results will include opening one-mile of fish passage comprised of 0.6 mile of Dieckman Tributary and 0.4 mile of its tributary, and restoring native floodplain forest.
Site 4 is a failed low water crossing adjacent to an active farm field and limits connectivity and fish passage in the Dieckman Tributary. It is located approximately 1,100 feet above the North Santiam River near river mile 9. This work will provide access to 0.4 miles of habitat through the removal of a fish passage barrier impacting 2 life stages for 2 species.
Proposed Action
Remove the low water crossing and regrade channel to improve connectivity between the tributary and Dieckman Creek. Proposed actions include constructing a coffer dam at upstream extent of work area, conducting fish salvage, material excavation and on-site disposal, hauling and dispersal of material for off-site disposal, and site reclamation. See uploads section for River Design Group Cost Estimate.
Conditions will be improved to increase fish passage, flow, and floodplain connection and function. Restoring fish passage and floodplain function is critical to providing refuge for ESA-listed fish including juvenile Chinook salmon and winter steelhead, and State sensitive species including Oregon chub and Pacific lamprey.
Grant funding was pursued through BPA's Anchor Habitat Investments for the next round of project opportunities. For this project, all 3 in-stream projects are identified in the Floodplain Restoration Alternatives Analysis developed by River Design Group, were chosen as the next "lowest hanging fruit" for implementation and are adjacent to existing restoration efforts. Site 4 is adjacent to the OWEB Restoration Grant 221-3001-18955 and will build upon fish passage/floodplain function improvement and 10 ac of floodplain forest restoration. | $31,932 | 13.51% | 06/01/2023 | 05/31/2025 |

Sites 5 is an undersized culvert on Dieckman Lane and limits channel connectivity, sediment continuity, and fish passage in the Dieckman Tributary. It is located near North Santiam River river mile 9. This work will provide access to 0.2 miles of habitat through the removal of a fish passage barrier impacting 1 life stage for 2 species.
Proposed action
Replace existing structure with appropriately sized pipe or small bridge arch to improve connectivity. During the design phase, both alternatives will be considered and evaluated. Proposed actions include work site dewatering, fish salvage, powerline drop and temporary power, existing culvert removal (excavation, stockpiling of fill, hauling of materials, removal/disposal of materials, removal/disposal of existing pipe), procure and install pre-fabricated bridge and streambed (including replacement bridge or culvert, ODOT Class 200 riprap at inlet/outlet, streambed matrix round and native gravels, and habitat boulders 2' - 3'), recondition existing site access road including base and surface rock, and site reclamation. See uploads section for River Design Group Cost Estimate.
Restoring fish passage and floodplain function is critical to providing refuge for ESA-listed fish including juvenile Chinook salmon and winter steelhead, and State sensitive species including Oregon chub and Pacific lamprey.
The Floodplain Restoration Alternatives Analysis recommended replacing the existing culvert with an appropriately sized pipe arch culvert to improve connectivity. The document was not a full analysis of any of the identified opportunities for floodplain restoration, but was a list of potential project locations with preliminary recommendations. Site 5 was one of many sites reviewed in the report; RDG did not spend much time analyzing the channel dimensions for the recommendations and Site 5 was not included in the five locations where additional analysis was completed. The following information summarizes the action alternatives to improve Site 5 and provides the engineering rationale for bridge selection.
ACTION ALTERNATIVES
Pipe Arch Culvert: In 2022, RDG reviewed Site 5 during development of the Phase 2 application. The active channel width was measured and ranged from 20 – 24 feet. Following the NOAA criteria of 1.5x the active channel width, the estimate for a crossing is 30 – 36 feet wide; the threshold for pipe arch culvert design width is 35 feet, but RDG’s professional opinion is to utilize bridges at that width. The benefit of the pipe arch culvert alternative is a lower cost as compared to the bridge. The disadvantage of the pipe arch culvert alternative is the reduction in flood capacity, which could be compounded if the headwall at the start of the channel is eventually replaced. If NOAA is willing to provide an active channel width variance, it may be possible to utilize a bottomless arch culvert around 20– 25 feet in width.
Small Bridge: Following the NOAA active channel width criteria, the estimate for a crossing is 30 – 36 feet wide which exceeds the pipe arch culvert threshold in portions of the project area. Preliminary designs estimate the bridge would be 35 feet wide, optimizing the active channel width and floodplain function and connection at the site. The benefit of the bridge alternative is the additional flood capacity, especially if the headwall at the start of the channel is eventually replaced. The disadvantage of the bridge alternative is a higher cost as compared to the pipe arch culvert.
RATIONALE
The action alternative selected is to replace the existing structure with a small bridge for three reasons. First, while NOAA may provide a variance on the active channel width since this is a floodplain channel, the professional opinion is to err on the conservative side and not expect a variance. Second, the estimate for a crossing is 30 – 36 feet wide, which exceeds the pipe arch culvert threshold in portions of the project area. Third, the bridge alternative provides the maximum floodplain function and flood capacity; this may be compounded over time as additional restoration efforts are implemented upstream.
