Public Funds and Financing - As enacted, authorizes use of the Hurricane Helene interest payment fund to pay local governments' loan charges; makes related changes. - Amends TCA Title 4; Title 5; Title 6; Title 7; Title 9 and Title 58.

SB 646 creates a $200 million Hurricane Helene disaster recovery fund to assist counties impacted by flooding from Hurricane Helene. The fund provides population-based grants to county governments for infrastructure repairs (e.g., $15 million for counties of 17,900-18,000 residents) and direct household assistance for property repairs, replacement of personal items, rent, and utilities. Funds must be allocated equally between county infrastructure grants and household aid, with counties administering applications and disbursements based on need. The law, now enacted as Public Chapter 521, ensures funds remain dedicated to recovery efforts without reverting to the general treasury.
