This bill establishes a prohibition on the use of federal funds for procuring emergency response maps starting in fiscal year 2026, unless those maps meet a detailed set of specific requirements. This measure aims to standardize the quality and utility of maps used by public safety agencies during emergencies. The core purpose is to ensure that federal resources are only expended on maps that are highly functional, accurate, and reliable for critical incident response. To be exempt from the funding prohibition, emergency response maps must be in a digital, accessible format, not stored outside the United States, and integrate with existing public safety software. Key requirements include displaying information oriented true north with a coordinate grid, showing floor plans with overlaid aerial imagery, and labeling critical features like access points, hazards, rooms, and stairwells. Furthermore, these maps must be verified for accuracy through a walkthrough inspection, be updatable, and made available without subscription fees to the procurer and relevant public safety agencies. The bill also mandates that the Secretary of Homeland Security, acting through the Director of the Cybersecurity and Infrastructure Security Agency, develop a comprehensive strategy within one year of enactment. This strategy will outline how the Federal Government will procure compliant emergency response maps for critical sites it owns or leases. It also addresses the distribution of these high-quality maps to all covered public safety agencies serving those federal locations, with a required congressional briefing on the strategy within 180 days of its submission.
