Thanks for visiting the Upper White River Channel Migration Zone (CMZ) Study participate.online website. Pierce County is conducting a CMZ Study along the Upper White River from the Town of Greenwater to upstream of Crystal River Ranch and Crystal Village along Highway 410. We are asking the community to be involved.

The draft Upper White River CMZ Study is now available! You can review the study through Feb. 21 and provide input on this website, or you are invited to join us in-person at one of our upcoming events.
