Disaster Financial Management Guide: Guidance for State, Local, Tribal & Territorial Partners [open pdf - 5MB]
From the Introduction: "Effective disaster financial management is critical for successful response and recovery. It helps jurisdictions obtain the resources needed to support their communities, increases the efficiency of recovery efforts and reduces the likelihood of audits and financial penalties for the jurisdiction. Fiscal and grant regulations are strict and apply to all jurisdictions, regardless of size, so it is imperative that all jurisdictions have robust scalable, flexible and adaptable disaster financial management plans and processes in place pre-disaster for all types of incidents."
