Comments: Location: East Rd. Stream: Ponding occurred immediately upstream of the pipe and began again ~30' downstream of the pipe. Bank undercut ranged from 6-12". Culvert: 3 overflow pipes and 1 functional pipe (see data form for placement). The main pipe is badly squashed allowing little water to pass. Pipe condition=3. Not embedded.
