Comments: Location: East Rd. Stream: Deep ponding occurred upstream, extended beyond 150'. Stream braids into 2 channels at the tailcrest. Excavation failed at the inlet and outlet, measurements taken at the substrate level. Culvert: The overflow pipe was embedded half the height throughout its length. The functional pipe was embedded with gravel 1-2' deep the entire length. Pipe condition=4-5 (Pipe has minor deficiencies but is still functional). Steel pipe with valve type ends.
