7-9-4: EXTENSION OF SERVICE:
   (a)   A Company shall be required to extend the System to and to offer the services of the System to Potential Subscribers where there are at least a total of thirty-five (35) residential dwelling units and/or "occupied commercial or industrial structures" per linear mile. Further, in the event that a tract or tracts within the Franchise Area is undeveloped at the time of a Grant, a Company shall, upon development of said tract or tracts, be required to extend the System (subject to the foregoing density requirement) in cooperation with public utilities servicing the tract or tracts.
   (b)   Notwithstanding a Grant, a Company shall obtain all necessary federal, state and local government permits, licenses and other required authorizations in connection with the establishment, construction, operation and maintenance of the System.
   (c)   Where adverse terrain or other factors render extension of the System and offer of services impractical or technically unfeasible, or creates an economic hardship, the Corporate Authorities shall, upon petition of a Company, either waive the extension of the System into such areas, or allow the extension and offer of services on such special terms, conditions and provisions as are reasonable and fair to the Village, a Company and Potential Subscribers in such areas.
