How improvement bonds are signed, recorded, and paid

(a) Improvement bonds shall be executed by the director of finance, or by a deputy of the director of finance duly designated by the director to execute such bonds, and issued pursuant to and under the authority and requirements of resolutions of the council. The bonds shall bear the lithographed or engraved facsimile signature of the mayor and shall be impressed with a lithographed or engraved facsimile of the seal of the County. If the council provides that no such improvement bond shall be valid or obligatory unless and until there shall be manually executed a certificate of authentication thereof, all signatures of County officials on the bonds may be facsimiles of their respective signatures. Interest coupons, if any, shall bear the lithographed or engraved facsimile of the signature of the director of finance. (b) The director of finance shall preserve a record of the bonds in a suitable book kept for that purpose. The council shall provide for books of registry to be kept for the registration of improvement bonds issued in fully registered form or which are subject to registration. (c) The bonds shall be payable only out of the moneys collected on account of assessments made for the improvement for which they are issued or from the reserve fund established pursuant to section 12-50, if the moneys collected out of assessments are insufficient to pay the bonds or the interest thereon as they become due. The County shall not otherwise guarantee payment of any bonds issued under the provisions of this chapter, provided that interest payments may be advanced by the council temporarily out of any moneys available in the County treasury.
