A. All utility services shall be below ground except that terminal boxes may be located above ground. If located within a street, the utilities shall be outside of the cartway except for required crossings. Lots which abut existing streets where overhead electric or telephone distribution supply lines and service connections have heretofore been installed may be supplied with electric and telephone service from these overhead lines, but any new service connections from the utilities' overhead lines shall be installed underground. In the case of existing overhead utilities, however, should a road widening or an extension of service or other such condition occur as a result of the development and necessitate the replacement or relocation of such utilities, such replacement or relocation shall be underground, if in accordance with Public Utility Commissioners' regulations.

B. The developer shall arrange with the servicing utility for the underground installation of the utilities' distribution supply lines and service connections in accordance with the provisions of the applicable standard terms and conditions incorporated as part of the servicing utility's tariff and on file with the State of New Jersey Board of Public Utility Commissioners. The developer shall submit to the Board, prior to the granting of final approval, a written instrument from each servicing utility which shall evidence full compliance or intended full compliance with the provisions of this section.
