§ 78-104. Implementation.

Before any traffic calming measure can be implemented, a traffic study must be undertaken by the transportation division, who will analyze the data and make the appropriate recommendations. Staff of the transportation division are available to make presentations and discuss their findings and recommendations to neighborhood associations and community groups. The recommendations that are made are based on engineering and design standards publications such as the AASHTO Green Book, the MUTCD (Manual on Uniform Traffic Control Devices), the TRB-Highway Capacity Manual, Fulton County Public Works Design Standards, and other design standards and regulations. Staff will use prudence and good judgement in their recommendations, so that the health, welfare and safety of the community are considered when recommending a traffic calming device. The following are some of the factors that will be consider for any traffic calming device to be implemented.

(1)

The county will only consider installation of traffic calming devices on streets classified as local, residential streets.

(2)

Traffic studies must confirm that a traffic related problem exist before the county will recommend a traffic calming device.

(3)

For speeding, the study must find that a speeding problem exist, based on the standard 85 ^th percentile speed of at least 11 MPH over the posted speed limit of the road.

(4)

For cut-thru traffic problems to be confirmed, the average daily traffic, peak hour volumes and directional turning movements will be compared to theoretical estimations as outlined in the most current (ITE) Institute of Transportation Trip Generation Guide.

(5)

For pedestrian and other safety related problems, confirmation will be made based on the accident data reports, inadequate roadway geometrics (such limited sight distance), school locations and other safety related parameters.

(6)

The county requires that there must be wide support from the community for implementing traffic calming measures in their neighborhood.

(7)

It is required that a formal petition be submitted to the county, showing that 75 percent of the property owners in the neighborhood and 90 percent of the property owners along the affected roadway affirm their support for installation of the traffic calming device. In certain circumstances, if number of residents supporting the petition is slightly less than that stated above, but a clear overwhelming majority support is shown for the initiative, the board of commissioners county may opt to waive these percentages.

(8)

The county transportation administrator may recommend the installation of traffic calming devices without the above percentages based on traffic safety.

(9)

The design of traffic calming devices must be safe and effective. The county requires that all traffic calming devices be designed as those outlined in this document (Appendix) [Not included in this Code]. Any variation from the standard designs must be approved by the transportation administrator, or his designee.

(10)

Once the traffic calming devices are installed, the county transportation division reserves the right to move, modify or remove the devices for operational or safety reasons at any time.

(11)

The neighborhood association may request to have any traffic calming device installed in their community removed. A formal petition will be required showing that 75 percent of the property owners in the neighborhood, and 90 percent of the property owners along the affected roadway affirm their support for removing these devices. Additionally, the neighborhood will be required to cover the cost associated with removing these devices.

(12)

The county may deny a request to remove a traffic calming device based on operational and safety reasons.
