Before any street is improved or paved, the Borough Clerk shall give notice to all persons owning property abutting on the street and to all public utilities and authorities operating in the municipality that the street is about to be paved or improved. All connections or repairs to utilities in any such street and all other work which requires excavation of the street shall be completed within 30 days from the receipt of the notice. The time for the completion of work may be extended, in writing, by the Superintendant of Public Works upon application by the person performing the work. This section shall not excuse any person from the requirement of obtaining a permit as provided in Article II.
A. 
No person to whom notice was given as provided in § 326-16 shall be issued a permit to excavate the street to which the notice related unless its issuance is approved by the Borough Council.
B. 
Subsection A above shall not apply to any case where the excavation is made necessary by the occurrence of some event which could not have been foreseen at the time that the notice was given or where the public health or safety required performance of the work in question.
