In DeKalb County, this is known as traffic calming and there are several phases to the process.  We’re currently working with the County on the planning stage.  There is a meeting to design the concept for our street at 2 pm on Friday, January 29, 2010 at:

1950 West Exchange Place
4th Floor
Tucker, Georgia 30084

Signs announcing the meeting will also be posted on the street.  We have confirmed with DeKalb County that the street will be maintained as needed after speed bumps are installed. 

After the design phase, we’ll need 65% of the homeowners on St. Patrick Street to agree to install the traffic breakers.  If you live in a rental home and would like to see the traffic slowed on St. Patrick Street, please speak to the homeowner about agreeing to installing them.  We’ll be asking for signatures later this spring.

A brief explanation of the Traffic Calming Program is provided at:

 A good State of the Practice document on Traffic Calming can be found at:

Note that this document addresses some measures that are not provided as options through the DeKalb Traffic Calming program, but it a great document for anyone trying to learn about traffic calming.

Tables 5.1 and 5.2 in Chapter 5 summarize impacts on speeds and volume of various measures.  FYI – When looking at the info on tables, please be aware that the County installs 22’ tables which have been shown to reduce speeds by 18%.

Please post any questions you have as a comment to this post and we’ll answer them for everyone to see.
