Road Closure and Detour: Culvert Replacement Project on North Peachtree Road

n ptree closed 2

Work has begun on the North Peachtree Road Culvert Replacement project. Project work requires a road closure at North Peachtree Road and a detour has been established for an estimated period of 45-60 days.  

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.
