Island County Flood History

Storm Surge/Tide — Jan 26, 2012

High wind occurred in the Admiralty Inlet area. Storm surge destroyed fences and yards in the Sandy point and Admiralty Inlet areas.

Coastal Flood — Dec 17, 2012

High astronomical tides coincided with low pressure to cause record high tide levels throughout Puget Sound. Many homes and yards along the shoreline were flooded.

Flood — Apr 3, 2009

Heavy rain over Whidbey Island, from a stationary Puget Sound convergence zone, caused enough flow on Glendale Creek to burst a beaver dam. Subsequent rain and plugging of a culvert on Glendale Road led to part of the road being washed away. The flood stream eventually damaged about 8 homes.
