About this file
This is a project location map (Attachment 7) for project SGBP 21-0048, showing utility infrastructure details at what appears to be Offutt AFB. The map details water line and storm line locations, including an 8" water line, 10" water line, and 36" storm line installations around SAC Boulevard and 55th Street.
The map contains several critical annotations regarding infrastructure work: a 36" storm line installed in 2020 that intersected with a 10" water line, requiring future work to go under the storm line; a new valve installation approximately 12' below grade; and investigation requirements for pipe segments, particularly segment A-D which requires a subsurface utility engineering Level A survey. The 10" water line is noted as poly material installed in 2016, though elevation data is unknown. The 36" storm line's elevation is documented from 969.48 to 969.31. The map includes reference points labeled A through D for tracking specific locations of infrastructure components.
