Design phase
Updated: January 8, 2026
Increasing stormwater capacity to reduce flooding and improve fish habitat and waterway access
Kellogg Creek flows through an undersized culvert causing the creek to back up at SE Thiessen Road and flood the road and properties upstream. We will replace the culvert with a larger culvert to allow water to move naturally for lower stream flows in the summer and higher stream flows from large storm events in the winter. Vegetation will be planted at both ends of the culvert to restore stream habitat.
Why
To decrease the frequency of flooding on the roadway and water backed up on adjacent properties upstream, and improve the habitat and ability for fish to pass through the culvert carrying Kellogg Creek.
