Construct and Repair Outfall 9 Culvert at Poorhouse Creek and Windy Hill Road

The project is located at Dobbins Air Reserve Base, Georgia. Project site is near the southeast edge of the base at Patrol Rd (1st St) and South Patrol Rd (Atkins Rd SE). The goal is to eliminate accumulation of heavy buildup of debris at the AT/FS structure upstream of the Culvert. Currently there is a failed gate like structure across the Outfall 9 Culvert also known as Poorhouse Creek. The existing structure consists of galvanized post placed vertically across the stream bed. The post prevents unauthorized personnel from accessing the base while allowing the waters from the poorhouse creek to pass. The posts are anchored to the culvert. The site is in the southeast of the base. Bank erosion and scour undercut the concrete base has necessitated the replacement of the structure with a permanent maintenance free solution. Extreme banks erosion has occurred on all sides. In addition during high rain events, debris accumulates at the AT/FS structure effectively damming up the stream causing further bank erosion. This project includes modification of the existing culvert structure, roadway, and fencing. Additionally, new spillways and ATFP structures will be constructed to replace the existing.
