Scheffler Creek Restoration: A How-To Guide

Scheffler Creek Stream Bank Restoration
ASLC AmeriCorps June Service Project



Step 1: The Prep
Scheffler Creek is located in town amid apartment buildings and culverts. However, it is also an important habitat for spawning salmon. Our goal with this project was to revegetate eroded areas of the stream bank to provide more habitat and prevent trampling. Krista joined in on the planning of this project midway with her weekly volunteer service at the Resurrection Bay Conservation Alliance (RBCA). Building up to the big day, she helped talk about the project at Seward Elementary and collect the willow cuttings used in the brush layering method.

Step 2: Get Dirty
The name of the game is stream bank stabilization. Weapons of choice were coir (biodegradable) log, spikes, shovels, sledgehammers. The eroded area was surrounded by beach grass but had become quite the gravelly slope. So to start us off, we dug a ditch for the coir log to act as the foot of our soon-to-be matching stream bank.

Step 3: More Ditch Digging
Enter the willow cuttings. After we dug another ditch uphill of the log, we had to lay lots of willow cuttings that will act as an anchor when their roots start to grow. It's actually pretty impressive that you can keep willow cuttings on ice from March until June, plant them, and enjoy. This part is where the name 'brush layering' comes from; we had a total of two layers on top of the log, then topped off by grass.

Step 5: The Scheffler Creek Shuffle
Turns out the willow need water. And the dirt needs to be packed down. This is where our cumulative 94 years of mudpie making experience really came in handy.

Step 6: Grass Transplants
Once the layers were in and the ground was even, we transplanted Beach Grass from the surrounding area to help cover the fresh topsoil. Fencing and signs block off the area to prevent further trampling while it's fresh. The light penetrating fish viewing platform will go in next month to prevent the area from being ruined again.
