Clear Creek Floodplain Restoration

The natural floodplain of Clear Creek has been severely constrained by retail/commercial development, roads, and road crossing culverts. Historically, agricultural activities also impacted the stream-riparian corridor and degraded the floodplain function through ditching of tributary streams and channelization of the creek itself.
The area around the confluence of the East and West Forks of the creek has been
especially manipulated.

 Project Description                                                                                        

The objective of this proposed project is to restore natural floodplain function and reduce the impact of stream flooding on downstream segments of the creek in the Silverdale corridor. The project must be designed such that flooding impacts are reduced on Silverdale Way and in the stream segment downstream of NW Waaga Way. This floodplain project, along with the replacement of the Bucklin Hill Road culverts at the estuary of the creek, should provide a more natural response to high-flow events.

The proposed project would accomplish the following:

1. Remove undersized culverts on the East and West Forks of Clear Creek.

2. Remove the existing road fill and pavement of Schold Road.

3. Restore floodplain and stream-riparian habitat in the Schold and Markwick reaches.

4. Restore off-channel wetland areas at the confluence of the East and West Forks.

5. Construct trails and footbridges along the restored portion of the creek to provide linkages to current biking and walking trails of the Clear Creek Trail network.
