Section 99.1039 - Financing project costs, issuance of obligations permitted, procedure - immunity from liability for obligations - retiring or refinancing debt, limitations1. For the purpose of financing development project costs, obligations may be issued by the municipality, or, at the request of the municipality, by the authority or any other political subdivision authorized to issue bonds, but in no event by the state, to pay or reimburse development project costs. Such obligations, when so issued, shall be retired in the manner provided in the ordinance or resolution authorizing the issuance of such obligations.2. Obligations issued pursuant to sections 99.1000 to 99.1060 may be issued in one or more series bearing interest at such rate or rates as the issuing entity shall determine by ordinance or resolution. Such obligations shall bear such date or dates, be in such denomination, carry such registration privileges, be executed in such manner, be payable in such medium of payment at such place or places, contain such covenants, terms, and conditions, and be subject to redemption as such ordinance or resolution shall provide. Obligations issued pursuant to sections 99.1000 to 99.1060 may be sold at public or private sale at such price as shall be determined by the issuing entity and shall state that obligations issued pursuant to sections 99.1000 to 99.1060 are special obligations payable solely from the funds specifically pledged. No referendum approval of the electors shall be required as a condition to the issuance of obligations pursuant to sections 99.1000 to 99.1060.3. In the event the obligations contain a recital that they are issued pursuant to sections 99.1000 to 99.1060, such recital shall be conclusive evidence of their validity and of the regularity of their issuance.4. Neither the municipality, the authority, or any other entity issuing such obligations, or the members, commissioners, directors, or the officers of any such entities nor any person executing any obligation shall be personally liable for such obligation by reason of the issuance thereof. The obligations issued pursuant to sections 99.1000 to 99.1060 shall not be a general obligation of the state, the municipality, or any political subdivision thereof, nor in any event shall such obligation be payable out of any funds or properties other than those specifically pledged as security for such obligations. The obligations shall not constitute indebtedness within the meaning of any constitutional, statutory, or charter debt limitation or restriction.5. Obligations issued pursuant to sections 99.1000 to 99.1060 may be issued to refund, in whole or in part, obligations theretofore issued by such entity pursuant to the authority of sections 99.1000 to 99.1060, whether at or prior to maturity; provided, however, that the last maturity of the refunding obligations shall not be expressed to mature later than the last maturity date of the obligations to be refunded.6. In the event a municipality or authority issues obligations under home rule powers or other legislative authority, the proceeds of which are pledged to pay for development project costs, the municipality may retire such obligations from funds in the special allocation fund in amounts and in such manner as if such obligations had been issued pursuant to the provisions of sections 99.1000 to 99.1060.7. State supplemental rural development financing shall not be used for retiring or refinancing debt or obligations on a previously publicly financed redevelopment project without express approval from the director of the department of economic development and the agricultural and small business development authority created pursuant to section 348.020. No approval shall be granted unless the application for state supplemental rural development financing contains development projects that are new projects which were not a part of the development projects for which there is existing public debt or obligations.
