Old Trail Block 22 – Pipe Re-inspection Summary
Date: March 9, 2021
Summary:
Roudabush Pipe Inspection Services conducted a video inspection on 2/26/21 of Old Trail block
22 at the request of March Mountain. The purpose of this inspection was to verify proper installation and
function of the installed Storm Sewer to VDOT standards. The facility was inspected with a Pearpoint
P350 wheeled crawler camera with a pan/tilt/zoom Camera. Wincan pipe inspection software was used to
document the inspections and produce an inspection report of the SWM facility. The inspection standards
used were NASSCO PACP and VDOT VTM 123.
Findings:
The post cleaning inspection identified one minor area of sediment (approximately 1’ to 2’ LF) remaining
that did not affect the inspection or functioning of the pipe. These pipes appear to meet VDOT standards
and should be accepted accordingly.
