Except as expressly provided hereinafter, all utility lines including but not limited to those required for electrical power distribution, telephone and telegraph communication, street lighting and television signal service shall be installed underground.

Easements shall be provided for the installation of utilities, or relocating existing facilities, in conformance with the respective utility company's rules and regulations.
