It's official. Seattle Department of Transportation (SDOT) will engineer safe streets around ALL Seattle schools!
Speed humps are highly effective, inexpensive, and quick to install. Seattle Neighborhood Greenways has been working closely with SDOT on a policy of engineered speed bumps around all schools, based on the Vancouver BC model of traffic calming on non-arterial streets in all School Walk Zones.
Speed bumps will be prioritized using the Vision Zero and Race & Social Justice lenses in the Safe Routes to School Action Plan. (That means the schools with the highest need get speed humps first.)
People who live in school zones that that are not highly prioritized for funding may request speed hump funding through Neighborhood Street Fund or Neighborhood Matching Fund.
The policy states "To discourage speeds above 20 mph all day, speed humps may be routinely installed on all non-arterials that are signed with 20 mph school speed zones. SDOT has evaluated the effectiveness of speed humps and speed cushions in school zones and found they are effective at reducing … speed to near 20 mph; and they nearly eliminate top-end speeders who drive more than 35 mph that pose the greatest danger for children walking and biking in school zones.(emphasis added)"
