Cybersecurity and Infrastructure Security Agency: Fiscal Year 2019, SAFECOM Guidance on Emergency Communications Grants [open pdf - 2MB]
From the Introduction: "The Department of Homeland Security (DHS) is mandated to administer responsibilities and authorities relating to the SAFECOM [safety communication] Program. Within DHS, the Cybersecurity and Infrastructure Security Agency (CISA) Emergency Communications Division--formerly the Office of Emergency Communications--is responsible for developing coordinated guidance for federal grant programs for public safety communications. As a result, CISA develops the annual SAFECOM Guidance on Emergency Communications Grants (SAFECOM Guidance) as a reference guide for entities applying for federal financial assistance for emergency communications projects. [...] The 'SAFECOM Guidance' provides general information on eligible activities, technical standards, and other terms and conditions that are common to most federal emergency communications grants. It aims to ensure that policies and standards across federal grant programs provide a consistent approach to improving emergency communications nationwide. The 'SAFECOM Guidance' achieves this consistency by aligning recommendations with the Nation's strategic plan for emergency communications, entitled the 'National Emergency Communications Plan' (NECP)."
