All assessments shall be levied by ordinance of the city and each other taxing unit assessed shall be notified in writing of the amount assessed against it. Then, such taxing subdivision assessed shall have the power to issue its general obligation bonds in an amount not exceeding the amount of its assessment and shall pay such assessment to the city from the proceeds of the sale of such bonds within 90 days from the publication of the assessment ordinance.

Such bonds shall mature in not more than 20 years from the date of issuance and shall bear interest at a rate not exceeding the maximum rate prescribed by Kan. Stat. Ann. § 10-1009, and amendments thereto, and shall be executed, issued, registered, sold and retired as provided by the general bond law. If deemed necessary or proper each such taxing subdivision may issue temporary improvement notes pursuant to Kan. Stat. Ann. § 10-123, and amendments thereto, to provide funds for paying its assessment prior to the issuance of its bonds.
