Flood Warning and Response

This activity addresses work done by your community's emergency management department. Elements award credits for work done to ensure rapid flood-threat analysis and response.

612.a
Flood threat recognition system (FTR)

Does your community have a system in place for identifying flood threats and warning residents?

Overview

Credits are awarded for flood threat recognition systems based on service level:

  • Level 1 is a manual flood threat recognition system that relies on manual volunteer work.
  • Level 2 is an automated flood alarm system
  • Level 3 is an automated flood warning system that provides time and depth information, which can come from the National Weather Service or U.S. Geological Survey. Coastal areas can use Sea, Lake, and Overland Survey from Hurricanes (SLOSH) models. You can use one or all of these systems, and may use different levels for different flood hazards. For credits, you must have a system for at least one location in your community 24 hours a day, and each system must have a corresponding map.

Considerations

This activity is unique in that you must receive credit for every element in this activity to get any credit at all. Additionally, you are required to have the following:

  • A description of the flood hazard including flood depths, historic floods, and special flood related hazards
  • An inventory of buildings and critical facilities in your community
  • A layered flood inundation map tied to different levels of response with at least three different flood levels
  • An adopted flood warning and response plan associated with the map that includes flood warning dissemination methods
  • One or more annual flood warning and safety outreach projects that tells community members how they will be warned and what they should do when a warning occurs
  • An annual exercise of the plan compliant with the National Incident Management System (NIMS) with an evaluation report.

Documentation

To receive credit for this element, provide:

  • A completed 600 series checklist that includes:

    • The flood hazard description
    • The flood inundation map
    • The flood warning and response plan and adoption
    • A description of the flood threat recognition system
    • The maintenance procedures for the community-owned gauge system, if applicable
    • An impact adjustment map showing the areas covered by each element (Flood threat recognition system (FTR), Emergency warning dissemination (EWD), Flood response operations (FRO), and Critical facilities planning (CFP)), and the number of buildings.

At annual recertification:

  • The outreach project documentation
  • A description of the flood exercise and evaluation report

Credit Calculation

Max: 75 for one of the following:

  • 25 credits for Level 1 manual system
  • 50 credits for a Level 2 automated system
  • 75 credits for a Level 3 automated flood warning system

The impact adjustment for this element involves dividing the buildings impacted by the flood threat recognition system by the total number of buildings in the Special Flood Hazard Area (SFHA).

612.b
Emergency warning dissemination (EWD)

How are you notifying your residents of flood hazards?

Level of effort = high

Overview

Your community can receive credit for having a flood warning dissemination system in place that reaches communities quickly. If the system utilizes sirens or text messages, you must test the dissemination method annually. Television notices and online messages do not require annual testing. Credit is awarded for the following subelements:

  • EWD1: providing pre-scripted messages and guidance
  • EWD2: providing information on flood levels and when to evacuate
  • EWD3: activating a siren system that covers the entire community
  • EWD4: identifying the agency responsible for door-to-door or mobile warnings
  • EWD5: identifying the procedures, staff, and equipment needed for door-to-door or mobile warnings, using the Emergency Alert System through all channels
  • EWD6: disseminating warnings over the telephone (EWD6)
  • EWD7: disseminating warnings over the television
  • EWD8: disseminating warnings using geocoding or over social media
  • EWD9: locating NOAA Weather Radios in schools, hospitals, nursing homes, prisons, and other critical facilities
  • EWD10: posting the flood inundation maps online

The procedures and messages should coordinate with the flood response preparation messages under Activity 330.

Considerations

You must receive credit for every element in this activity to get any credit at all. Additionally, you must have the following:

  • A description of the flood hazard including flood depths, historic floods, and special flood related hazards
  • An inventory of buildings and critical facilities in your community

  • An adopted flood warning and response plan associated with the map that includes flood warning dissemination methods
  • One or more annual flood warning and safety outreach projects that tells community members how they will be warned and what they should do when a warning occurs
  • An annual exercise of the plan compliant with the National Incident Management System (NIMS) with an evaluation report.

Documentation

To receive credit for this element, you must provide:

  • A copy of the flood warning and response plan with EWD items marked
  • For EWD10, copies of the written warning materials
  • For EW1, 2, 5, 6, or 7, the pre-scripted messages
  • For EWD3, the impact adjustment map with siren locations and coverage

612.d
Critical facilities planning (CFP)

Developing intelligence around your community's critical facilities can help you ensure that they are protected during flood hazard events.

Level of effort = high

Overview

As evidenced in other CRS elements, your community can receive credit for protecting critical facilities. The CRS defines critical facilities as facilities needed during flood response and recovery as well as facilities that could be hazardous if flooded. To get credits, start by making a list of critical facilities, and contact the facilities to make warning arrangements if needed (CFP1). From there, you can develop and review individual critical facility response plans for additional credit (CFP2). If there are no critical facilities that can be impacted by flooding, you must state this and provide a definition of critical facilities.

Considerations

You must receive credit for every element in this activity to get any credit at all. Additionally, you need to have the following:

  • A description of the flood hazard including flood depths, historic floods, and special flood related hazards
  • An inventory of buildings and critical facilities in your community
  • A layered flood inundation map tied to different levels of response with at least three different flood levels
  • An adopted flood warning and response plan associated with the map that includes flood warning dissemination methods
  • One or more annual flood warning and safety outreach projects that tells community members how they will be warned and what they should do when a warning occurs
  • An annual exercise of the plan compliant with the National Incident Management System (NIMS) with an evaluation report.

Documentation

To receive credit for this element, provide:

  • A list of the critical facilities
  • The list of critical facilities with flood warning and response plans, if applicable (CFP2)
  • A letter stating that there are no critical facilities that can be impacted by flooding, if applicable

At annual recertification:

  • A page from the list of critical facilities, updated annually

Credit Calculation

Max: 75

Up to 25 credits are awarded for providing the contact information of critical facilities, and arranging for flood warnings to those locations. Up to 50 credits are awarded if the critical facilities have their own community approved flood warning and response plans. There is no impact adjustment for this element.
