As our year gets off to a soggy start – more than twice the normal rainfall as of early today – saturated soil has slid in at least two West Seattle spots:
That slope between the 2000 block of Bonair and the 1700 block of Alki had a slide last Wednesday, witnessed and photographed by Kevin Freitas. He alerted the city, which has since “yellow-tagged” one house on Bonair. Department of Construction and Inspections spokesperson Bryan Stevens told WSB, “The slide was approximately 15 feet wide as it ran down the slope and was contained within the boundaries of this property.”
Stevens continued, “We didn’t observe damage to the home itself (built on concrete piles), but the existing block retaining wall was damaged. Upon inspection, we posted a yellow tag, which allows occupancy of the home but notes the need to repair the wall and hillside. The owner was notified to obtain a Geotechnical Engineer to evaluate and stabilize the hillside.”
We also asked him about another reader report, a slide in the Eddy Street Ravine area northeast of Lowman Beach, north of the 6400 block of dead-end 49th SW: “A surface slide occurred at the top of the slope and deposited debris at the bottom of the unopened street end. We have relayed this to SDOT, and Seattle Public Utilities is taking lead on followup, given the potential impact to their infrastructure.”
If you are on or near a slope, landslide awareness is vital, especially in times like right now when there’s little time for the ground to dry out between storms. City advice on prevention, and what to do if a slide happens, is here.
