The mudslides that temporarily closed East Pioneer between 33rd Street SE and SR 162 in February are tangible reminders of what can happen when water (whether rain or melting snow) destabilizes hillsides. Here in Puyallup, the valley gives rise on our south to a hill, and that topography renders some of our landscape naturally susceptible to slides.
The Washington State Department of Natural Resources provides information on warning signs of a potential landslide. These include:
- Increased seep activity on a hillside, or newly saturated ground;
- Trees beginning to tilt on a hillside;
- Sticking windows or doors, or new/growing cracks in walls, ceilings or foundations; and
- The movement of soil away from structural foundations.
Report signs of a potential landslide to the City's Public Works Division at 253-841-5505. You can read more about landslide hazards and how to reduce your risk via the link below.
