On sheet 7 of the plans, notes 9 and 10 discuss exposing existing culverts. Can you provide the approximate flowline elevations of these pipes?

The estimated depth of the existing 30” RCP is approximately 7.5’ from ground to flowline of the pipe. The estimated depth of the existing 24” RCP is approximately 4.5’ from ground to flowline of the pipe. These depths are only estimates based on available survey information and engineering assumptions on the slope of the pipes, and will need to be verified in the field. (12/29/2020)
