Dunwoody announces North Peachtree Road will be detoured for Critical Culvert Replacement Project

The North Peachtree Road Culvert Replacement project is about to be underway. Project crews will begin initial work starting the week of November 30th; the road closure and detour will begin December 2nd, weather permitting.

Based on the culvert’s existing condition and hydrologic modeling, it is necessary and prudent to replace the failing 6 foot corrugated metal culvert. The culvert is located on North Peachtree Road, just south of the intersection with North Peachtree Way. The new conveyance will be a 9 foot by 4 foot reinforced concrete box culvert. Hydrologic study and discussions with adjoining property owners indicate that stormwater overtops this portion of North Peachtree Road during significant rain events. It is estimated that this flooding occurs at a frequency of 5 to 10 years.

In addition to using a larger and stronger culvert, the city will also raise its invert to accommodate higher stormwater flows. The new culvert will convey the 100 year flood.

The construction project has been coordinated with both the Kingsley Lake Association and the adjoining property owners impacted by construction. The Kingsley Lake Association has agreed to lower the lake level 4’ to accommodate the construction in October, when fish populations and recreation will not be significantly impacted.

For additional information on this culvert replacement project please contact Public Works at 678.382.6850 or visit the North Peachtree Road Culvert Replacement project page.

 P.S. - Don't speed through this detour as I believe it will be closely monitored.
