Living along the Lower Skykomish River
To help residents better understand the flood hazard risk along the Lower Skykomish River and what programs are available, two short presentations have been recorded. Click the video image below to watch the presentation.
Purpose
An important goal of the Community Floodplain Solutions (CFS) program is understanding and predicting future risks associated with changing river conditions. Over time, the Skykomish River moves across its floodplain. This channel migration can occur gradually as the river erodes one bank and deposits sediment along the other. It can also occur abruptly, when a channel shifts into a new or previously occupied location.
The purpose of flood hazard mapping studies funded through CFS is to model, assess and map river conditions to inform future projects. Flood hazard mapping typically looks at water depth -- how much water is in the river channel or on the floodplain. These studies also look at the river's changing shape and location, not just water depth, across a broader reach scale.
CFS teams aim to understand and predict risk into the future by asking these questions:
