Unpaid special assessments interest accrual rate modification provision and requiring refunds of certain payments on interest provision

This bill modifies the interest rate applied to unpaid special assessments for local infrastructure projects (like roads or sewer improvements). It requires refunds for interest paid under the previous rate on certain assessments. The change directly affects property owners who pay these special assessments, as it alters how interest is calculated and mandates refunds for overpaid interest. The bill amends Minnesota Statutes section 429.061 to implement these specific interest rate and refund provisions.
