Lower Clackamas Windswept Side Channel Re-connection
Project Overview
Basics
Lower Clackamas Windswept Side Channel Re-connection
Proposal
The Lower Clackamas River watershed encompasses 15,428 acres of mostly industrial, urban, and residential development. The project would reconnect a historic side channel, add large wood structures, improve native plant densities and manage invasive species. There are existing barbs, and dikes on this property that would need to be modified or removed. There are two side channels that would be reconnected. The first is 2700 feet and the second is 1700 feet totaling 4400 feet of off channel habitat that would be created. This stretch of the Lower Clackamas would have been highly complex with multiple channels but over the years the river has been confined to a single channel.

Notes
| 12/05/2017 2:42 PM | Zachary Bergen | Project Prioritization: 1.) Focal species affected: - Three or more 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)- 3/4 to 1 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. |
