Plans are under way to gage community interest in installing two speed humps on Wayne Drive in Annandale’s Broyhill Crest neighborhood as a “traffic calming” measure.
At a community meeting at the Mason District Government Center Dec. 9, residents reviewed the conceptual plan drafted by the Fairfax County Department of Transportation (FCDOT). Residents of affected streets will be given a chance to vote on the proposal, and if they approve it, it will go to the Fairfax County Board of Supervisors for a final decision.
According to FCDOT, the speed humps would be 12 feet long and 3 inches high. FCDOT says “research has found these dimensions to be the best compromise between being severe enough to slow most vehicles, yet forgiving enough to not unduly impact emergency response times.” A speed hump can slow fire trucks and other emergency vehicles by about 3 to 10 seconds.
FCDOT also says speed humps that are only 3 inches high would not hinder snow removal but could lead to increased noise level “where the total percent of heavy truck traffic volume is 20 percent or greater.”
“There is no evidence to suggest that traffic calming measures either raise or lower residential property values,” FCDOT says. “It is likely that for every person who feels they detract from the value of a property, there is another who feels their safety benefits add to the value of a property.”
