Preliminary Damage Assessments (PDAs) are conducted to enable FEMA — as well as state, local, tribal, and territorial partners — to determine the magnitude of damage and impact of disasters.

How to Conduct a Preliminary Damage Assessment

1. Local Damage Assessment

The process starts at the local level where damage details are initially collected, shared, and validated by state, tribal and territorial authorities.

2. State or Tribal Verification

The state, tribe or territory generally has 30 days from the start of the incident to determine whether or not federal assistance in the form of FEMA Individual AssistancePublic Assistance or other federal programs may be necessary.

Not every incident will result in the need for a PDA or federal assistance. Extensions may be granted upon request.

3. Joint PDA

If the incident is of a severity and magnitude that resources needed to recover are expected to exceed local and state or tribal government capability, the director of the state or tribal emergency management agency may request a Joint PDA from the appropriate FEMA Regional Administrator to validate damage and evaluate impact. This request should include any counties or tribal lands to be assessed and will begin discussion on the general timeline for the Joint PDA.

4. FEMA Regional Office

Once a request for a Joint PDA is made, a summary of the information verified by the state or tribal emergency management should be provided to the FEMA Regional Recovery Division. FEMA programmatic representatives should coordinate with state or tribal emergency management to discuss the information submitted, determine team requirements, establish a PDA briefing time and location, and develop an overall PDA coordination plan.

5. FEMA Headquarters

FEMA Headquarters reviews the request to ensure it's consistent with declaration policy and process. The FEMA Administrator will then review the request, informs and makes recommendations provided by the Regional Administrator.

6. President

The President of the United States makes the disaster declaration decision.

Digital Damage Surveys

FEMA’s damage assessment survey templates for both Individual and Public Assistance are available for state, local, tribal and territorial partners to use during the Initial Damage Assessment (IDA) process.

The standardized input fields allow jurisdictions to collect the same information that FEMA gathers during the Joint PDA operation. This information is used to determine whether the jurisdiction is eligible for a disaster declaration. The data captured using these templates is immediately available in the jurisdiction’s ArcGIS Platform and can assist in FEMA’s review of the damages in the event a Joint PDA is requested.

Survey Templates

Sharing Initial Damage Assessment Data with FEMA

FEMA can accept initial damage assessment (IDA) geospatial datasets from state, tribal, and territorial (STT) governments for upload into FEMA’s Field Assessment and Collection Tools (FACT) System. The FEMA Regional Office can review this data for situational awareness when coordinating the logistics for a Joint PDA field operation or for remote validation of damages during a virtual Joint PDA operation.

ArcGIS Solution that leverages the above survey templates is available to support States, Tribal Nations, Territories, and local organizations in the Initial Damage Assessment (IDA) process.

The Damage Assessment Solution enables organizations to electronically collect damage reports, assign initial damage assessments, monitor the impact of a disaster on the community, brief stakeholders, and share information with the public using ArcGIS. Information that is collected can be shared with FEMA Regional coordinators in a collaboration group for use during the Joint PDA process.

Organizations utilizing Esri geospatial software can learn more about how to deploy the ArcGIS Solution for Damage Assessment and how it works by visiting the Esri Damage Assessment solution page. This ArcGIS Solution is fully supported by Esri technical support should you need technical assistance configuring the solution.

Survey123 for PDAs enables FEMA and SLTTs to electronically collect, submit and validate damage assessment information immediately following a disaster. It provides the capability for all levels of emergency management to collect the same information.

The survey utilizes GIS technology and allows users to easily collect detailed damage information including:

  • Location
  • Category of damage
  • Ownership and insurance information
  • Cost estimates
  • Other local community impact information
