Are YOU Prepared for Landslides?
SEATTLE — Did you know that most landslides occur between the months of October and April? And that 86 percent of landslides are caused to some extent by human activity? Landslide season is upon us and although the Seattle rainfall is currently below the landslide threshold, the City of Seattle is urging residents to take preventive measures to protect themselves and their property from possible landslides.
Landslide experts agree there is not one single factor that contributes to landslides in the area, but in most cases there are steps that property owners can take to mitigate risk.
With 20,000 Seattle properties (mostly residential) in landslide-prone areas, the
The free landslide awareness meetings will give the public the opportunity to consult with public/private landslide experts and learn simple preventive measures that will help protect them from future landslides, such as the following:
2012 City of Seattle Landslide Awareness Meeting
The landslide awareness meetings will include a presentation that discusses the causes of landslides, proper drainage for sloping sites, and vegetation maintenance on slopes. The presentation will be followed by a question and answer session and time for one-on-one discussions with professionals in the field, including the City of Seattle, and volunteers from The American Society for Civil Engineers, The Association of Engineering Geologists, The International Society of Arboriculture, and Associated Building Contractors.
Oct. 27, 10:00 a.m. – 12:00 p.m.
Nov. 10, 10:00 a.m. – 12:00 p.m.
The landslide record that was documented in the Seattle Landslide Study of 2000 indicates that 86 percent of landslides that have occurred in the city have some human influence such as excavating and filling on steep slopes, broken pipes and uncontrolled storm water.
Since the devastating landslide season of 1996/1997, which involved over 300 reported landslides, the city has taken steps to prepare and respond to slides by constructing mitigation projects to reduce the potential for future slides. It has also been presenting these public landslide awareness meetings for owners of landslide-prone property.
If a landslide damages your property and you have an immediate concern for your safety, leave the premises and call 9-1-1. Seattle property owners with structures that may be affected by or endangered by a landslide should contact a geotechnical professional for structural evaluation.
