Relating to the development of a severe weather adaptation plan by certain entities.

HB 256 requires 13 specific Texas state agencies - including the Department of Agriculture, Public Safety, Health and Human Services, and the Public Utility Commission - to develop and publish severe weather adaptation plans every even-numbered year by September 1. Each plan must include a vulnerability assessment, analysis of budget impacts over 2/5/10 years, funding sources, and a strategy for monitoring weather effects. Agencies must post these plans on public websites and submit copies to the governor, lieutenant governor, and legislative leaders. The bill directly affects state agencies responsible for emergency management, infrastructure, and public safety, mandating science-based planning to prepare for severe weather events.
