Sec. 22-44. Tunnels.

 

(a) No tunneling or under-cutting of banks in any trenches or openings in pavement will be permitted. All banks shall be cut straight down vertically from the surface of pavement so that the hole or trench may be properly backfilled and tamped.

 

(b) Small tunnels will be permitted for the installation of service pipes or other construction passing under the curbing or under curb and gutter, but the natural earth shall not be removed nor disturbed for a depth of not less than three (3) feet immediately beneath the lower edge of such curb or gutter, and the person to whom the permit is issued shall be held responsible for a period of one year for any subsequent settlement or damage to the curb or gutter when caused by his work.
