Lesson Plan: The Power of Geographic Data: FEMA Floodplain Maps

How the National Flood Insurance Program works

Orice Williams Brown, director of the Government Accountability Office - Financial Markets and Community Investment describes the origins and function of the NFIP.

Description

Geographers use geographic data to create maps that solve real world problems. These maps can guide individuals, communities and states in making decisions about how best to interact with the environment. An important consideration in land use planning is the construction of homes, businesses and infrastructure on floodplains. Each year, flooding causes more damage to human built infrastructure than any other natural process. The Federal government teams with local insurance providers to offer flood insurance through the National Flood Insurance Program (NFIP). The Federal Emergency Management Agency (FEMA) oversees this program. The Federal government provides subsidies to homeowners and businesses located in floodplains to defray the high cost of insurance. Insurance rates are much higher if a FEMA map determines your property is located in a flood plain. But how are these maps created, and where does the data come from? These are important questions because floodplain maps have a real impact on individual families, business owners and communities as they seek to obtain affordable insurance and plan infrastructure and development projects that mitigate flood water damage.

Procedures

  • Warm-Up

    Answer the following questions to begin class.

    1. Do you think floods are predictable?

    2. How can we prepare for a flooding event?

    3. Who do you think pays more for car insurance, risky drivers with accidents and speeding tickets or safe drivers with no speeding tickets? Explain your answer.
  • Introduction

    Geographic data is important in predicting the frequency and severity of floods. In this lesson, students will be introduced to the importance of floodplain maps and how they are used to assess risk, determine insurance rates and guide zoning and planning efforts. They will have access to real FEMA floodplain risk assessment maps and use them to make decisions about land use and planning. Key to student understanding in this lesson is the ability for students to make the connection between how the geographic data as depicted on the floodplain maps affects individuals and communities by setting insurance rates, subsidies through NFIP, and dictating how flood-prone areas can be developed and utilized.

    Have the students watch the videos and answer the questions on the FEMA Floodplain Maps handout. After discussing their answers and ensuring they have a clear connection between the use of floodplain maps and the setting of insurance rates and the delivery of subsidies, Instruct the student to participate in the FEMA Floodplain Map activity.
