County of Fairfax, Virginia Department of Transportation Citizen Feedback Sent: Friday, July 15, 2011 4:03 PM To: Mason BOS Email Subject: Speed Hump I want to express my appreciation to you, and to others, who succeeded in getting our speed hump in place. The workmen were professional and hardworking, and had the first part done by noon on Monday. They were very accommodating about accessing our driveway, and did not inconvenience us in any way. Their work was cleanly done. Tuesday, they returned for the final work to be done, and it was accomplished quickly. The best part is watching everyone SLOW down as they come to the speed hump. We have seen a great difference in the speed with which cars and trucks go by our home. For us, and I hope for the other residents of Lincolnia Park, this project has been a great success. Again, many thanks to everyone. Sincerely, Sent: Thursday, August 04, 2011 1:50 PM To: Knudsen, Steven K Subject: Just saying Thank You!

Drivers are respecting the measures and I feel much less urgency in getting across the street. I'm assuming the low volume is summer traffic patterns versus folks avoiding the new measures-we'll see here in a few weeks when school gets started. Hope all is well in your world.

10. County of Fairfax, Virginia Department of Transportation Citizen Feedback Our children, pets, and wild animals were in constant danger. Just trying to back out of our driveways in the mornings became a game of Russian roulette. And, sadly, it was not uncommon to see the carcasses of wild animals lying in the street. Something needed to be done. The county government came up with the solution. This year, they installed three major speed barriers at regular intervals along Lemon Road. They call them speed humps, but they will seem more like mountains if you forget and try to cross them at more than 15 miles an hour. Do they work? You bet your sweet life, they do. We are now back to traffic at reasonable speeds. The slight inconvenience we occasionally experience is made up for by the knowledge that our children, pets, and the wild animals in the area are now safer. So, the next time you are driving along Lemon Road and feel inconvenienced by our speed humps, please take a deep breath and try to remember all the good they are doing. November 8. 2010

11. County of Fairfax, Virginia Department of Transportation Conclusions The spacing of the traffic calming devices has a significant impact on the reduction of the 85 th percentile speeds, when spaced between 600 to 800 feet apart. The devices are effective in reducing both the 85 th percentile and average speeds of vehicles driving on neighborhood streets in Fairfax County. Recommendation that the traffic calming program be continued.
