§ 7-1.409. Pipes and conduits: Cover.

The minimum cover over any pipe or conduit installed under any public street shall be thirty (30″) inches of material measured vertically from the existing or proposed flow line of the nearest gutter to the top of the pipe or conduit. If a gutter flow line is not established, the cover shall be thirty (30″) inches of material measured from the surface of the nearest outermost edge of the traveled way to the top of the pipe or conduit. Where there are existing curbs and gutters or where curbs and gutters are under construction, utilities may maintain a minimum sixteen (16″) inches of cover starting one foot back of the curb line in the parkway or sidewalk areas. The Director of Public Services may permit the installation of pipes or conduits at lesser depths where the required cover cannot be provided.
