SECTION 88. ADDITIONAL METHOD OF IMPROVING STREETS AND ALLEYS.
   In addition to the method provided for paving street, by Section sixty-one of the Charter of the City Dunbar, the Council may order any street, avenue, public alley, or portion thereof, to be graded and paved, repaved, or otherwise permanently improved, and the Council may order the Mayor and City Clerk to issue a certificate for each installment of the amount of the assessment to be paid by the owner of any lot or fractional part thereof fronting on such street, avenue or alley. The amount specified in said assessment certificate shall be a lien as aforesaid in the hands of the holder thereof upon the lot or part of a lot fronting on such street, avenue, or alley, and such certificate shall draw interest from the date of said assessment and the payment may be enforced in the name of the holder of said certificate by proper suit in equity in any court having jurisdiction to enforce such lien; the Council shall fix the amount of such assessment, advertise for bids and do all other things in connection therewith as is provided for paving or permanently improving any street or alley or any portion thereof in Section sixty-one, except that such assessment laid under this section shall include the whole cost of such improvement, including the cost of grading and paving squares at intersections of streets and curbing, the cost of which intersections shall be apportioned against the several properties fronting upon thereof so improved; and such certificates shall be issued in the same number of installments and payable at the same time as other paving or permanent improvements are provided to be paid for, and shall be a lien in the hands of the holder thereof upon the particular lot against which they are assessed in the same way and manner that assessments are liens under Section sixty-one of said Charter. And nothing contained in this Charter of the City of Dunbar shall be construed as imposing a time limit upon the enforcement by appropriate suit of any lien for public improvements, heretofore or hereafter created.
   Certificates authorized by this section may be issued, sold or negotiated to the contractor doing the work, or to any other person if the Council deems it expedient: Provided, that the City in issuing such certificates shall not be held as guarantor or in any way liable for payment thereof, except upon the direct action of the Council expressed by resolution of record before sale.
   Certificates so issued shall contain a provision to the effect that in the event of default in the payment of any one of said certificates, when due, and said default continuing for a period of sixty days, then all unpaid certificates shall become due and payable and the holder of said certificates may proceed to collect all such unpaid certificates in the manner hereinbefore provided.
