Section 97.
No resolution to proceed with any improvement, the cost of which is to be paid by special assessment, shall be introduced in Council, unless a petition shall have been filed with the Commissioner of Engineering asking for such improvement, except as hereinafter provided.
Such petition shall state accurately the nature and location of the proposed improvement, and waive the rights of the signers thereof to any and all exemptions against assessments that may be made to pay for such improvements.
Such petition shall be signed by the owners of two-thirds of the foot frontage of the property abutting on the street or portion of the street so to be improved.
In case of an extraordinary emergency or public necessity, Council may, by three-fourths vote of all its members, proceed with any street improvement, without a petition being previously filed.
