Hello! I live on Jefferson Street. Thank you for the two speedbumps! At least one (probably two) are needed on the opposite side of the hill from where the current two are located. the crew that installed the two current ones told a neighbor that more would be coming, but it has been a couple of weeks. I am the owner at 180 Jefferson street and you are welcome to put them directly in front of my house. I know my neighbor across the street would also welcome them.
Thank you very much!
