video is required 30’ into connecting streets. Video shall extend to the first manhole of the connector
Street. If the first manhole is less than 30’ into the connecting street, video shall extend to the next

manhole in that street.

Laterals of catch basins shall be videoed even when they extend more than 30’ into connecting streets.
In all situations, lateral videos shall be from the catch basin to structure or main line pipe.

In the event CCTV inspection cannot be performed by the contactor due to major debris accumulation
and/or blockage, the contractor will clean the lines again then continue with the inspection. In addition,
