Ala. Code § 11-98-2
The creating authority may by ordinance or resolution, as may be appropriate, create within its respective jurisdiction districts composed of the territory lying wholly within the municipality or of any part or all of the territory lying wholly within the county. The districts shall be political and legal subdivisions of the state, with power to sue and be sued in their corporate names and to incur debt and issue bonds. The bonds shall be negotiable instruments and shall be solely the obligations of the district and not the State of Alabama. The bonds and the income thereof shall be exempt from all taxation in the State of Alabama. The bonds shall be payable out of the income, revenues, and receipts of the district. The bonds shall be authorized and issued by resolution or ordinance of the creating authority of the district and shall be of such series, bear such date or dates, mature at such time or times, not to exceed 30 years from issuance, bear interest at such rate or rates, be in such denominations, be in such form, without coupon or fully registered without coupon, carry such registration and exchangeability privileges, be payable in such medium of payment and at such place or places, be subject to such terms of redemption, and be entitled to the priorities on the income, revenues, and receipts of the district as the resolution or ordinance may provide.
All bonds shall contain a recital that they are issued pursuant to this chapter, which recitals shall be conclusive that they have been duly authorized pursuant to this chapter.
