The City of Burien is reporting that a small landslide has occurred along the southern shoreline of Seahurst Park, just above the trail and beach.

As a precaution, the trail and beach south of the Seastar picnic shelter (graphic above) will be closed to the public until the hillside’s stability can be properly assessed. The closure limits will be marked with barricades and signage until a determination is made regarding public safety.

As a reminder, rainy weather brings increased risk for landslides. Learn how to spot a landslide! And if you see one in progress—get to safety and call 9-1-1.

Landslide Warning Signs:

  • Springs, seeps, or saturated ground in areas that have not typically been wet before.
  • New cracks or unusual bulges in the ground, street pavements or sidewalks.
  • Soil moving away from foundations.
  • Ancillary structures such as decks and patios tilting and/or moving relative to the main house.
  • Tilting or cracking of concrete floors and foundations.
  • Broken water lines and other underground utilities.
  • Leaning telephone poles, trees, retaining walls or fences.
  • Offset fence lines.
  • Sunken or down-dropped road beds.
  • Rapid increase in creek water levels, possibly accompanied by increased turbidity (soil content).
  • Sudden decrease in creek water levels though rain is still falling or just recently stopped.
  • Sticking doors and windows, and visible open spaces indicating jambs and frames out of plumb.
  • A faint rumbling sound that increases in volume is noticeable as the landslide nears.
  • Unusual sounds, such as trees cracking or boulders knocking together, might indicate moving debris.
