North Peachtree Road Culvert Replacement Project

North Peachtree Road Culvert Replacement Project

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.

Project Update

North Peachtree Road Reopened (as of 12/22/15)

Work on the culvert replacement project was completed ahead of schedule and the section of North Peachtree Road is once again open to vehicle and pedestrian traffic.

Work at the project site will continue as crews coordinate additional project activities, site clean-up and restoration. This critical infrastructure upgrade project helps to address stormwater overflows on this portion of North Peachtree Road during significant rain events.  Crews have installed a larger and stronger culvert, and replaced the failed 6 foot corrugated metal culvert with a new 9 foot by 4 foot reinforced concrete box culvert.  

Please be alert and use caution when driving or walking through the area as construction activities continue.
