Project Overview
Basics
Lower Clackamas/ Foster Creek Confluence Remeandering
Deferred
Realignment of Foster Creek would result in 1,450 linear feet of side channel habitat increase. Roughened channel construction is anticipated to encourage occupation of the former channel alignment, support salmonid access, and protect upstream infrastructure.
1,200 linear feet of large wood placement is proposed. Placement includes six habitat complexity log jams, (eight to twelve pieces each), distributed throughout the re-occupied Foster Creek channel. These
structures are intended to provide cover and complexity and would be placed to avoid impact to existing mature vegetation. Five buried channel margin jams will redirect flow down the former alignment.

Notes
| 12/05/2017 1:53 PM | Zachary Bergen | Project Prioritization: 1.) Focal species affected: - Two species 2.) Limiting factors addressed: - Addresses two or more primary and at least one secondary 6e 3. Physical habitat quality: Degraded channel structure and complexity. 6e 4. Physical habitat quality: Degraded floodplain connectivity and function. 6e 1. Physical habitat quality: Degraded riparian areas and large wood recruitment. 3.) Project protection benefits: - Minimal protection from private landowners. 4.) Processed-based restoration -Partial restoration- Project partially addresses restoring natural processes. Restoration actions would include wetland enhancement, riparian restoration, the creation of side channels, invasive species removal, and native plantings. 5.) Threats addressed: -Climate change resiliency- Restoration partially or fully addresses climate change resiliency and the project focuses on key habitats that provide resiliency. - Urbanization/development impacts- Restoration actions partially address habitat and watershed processes associated with current and future watershed urbanization. 6.) Project size and scale: - Stream projects (linear scale)- 1/4 to 1/2 mile in length - Floodplain/ riparian area extent (lateral extent)- Project includes some floodplain/riparian activities. 7.) Project readiness, constraints, and risks: -Project readiness- The project's conceptual design does consider other factors such as constructability and how project effectiveness will be demonstrated. -Project constraints and risks- There are moderate feasibility constraints or risks that may limit overall project success. 8.) Outreach, landowner relationship, and socio-economic benefits: -Unknown if landowners support tours or outreach activities on their properties. |
