GIS and Floodplain Administration

Geographic Information Systems (GIS)

Geographic Information Systems (GIS) are frameworks for gathering, managing, and analyzing spatial and geographic data. GIS integrates various types of data and uses spatial location as the key index variable. It allows users to visualize, interpret, and understand data in ways that reveal relationships, patterns, and trends in the form of maps, globes, reports, and charts. Key components of GIS include:

  1. Data Collection: Gathering spatial data through various means such as satellite imagery, aerial photography, GPS, and surveys.

  2. Data Storage: Storing spatial data in databases that can handle large volumes of data.

  3. Data Analysis: Using spatial analysis tools to perform complex analyses like buffering, overlaying, and network analysis.

  4. Visualization: Creating maps and other visual representations to display data and analysis results.

  5. Application: Implementing GIS in various fields such as urban planning, environmental management, transportation, and disaster management.

Floodplain Administration

Floodplain Administration involves the management and regulation of land use within floodplain areas to minimize the risk and impact of flooding. This administration typically focuses on ensuring that development in flood-prone areas complies with federal, state, and local regulations designed to protect people, property, and the environment. Key activities in floodplain administration include:

  1. Mapping and Analysis: Identifying and mapping floodplains using tools like GIS to delineate flood-prone areas and analyze flood risks.

  2. Regulation and Permitting: Enforcing building codes, zoning laws, and land use regulations to prevent inappropriate development in floodplains.

  3. Mitigation Planning: Developing and implementing strategies to reduce flood risks, such as constructing levees, flood walls, and other infrastructure.

  4. Public Education and Outreach: Informing the community about flood risks and promoting practices to reduce vulnerability to flooding.

  5. Emergency Response and Recovery: Coordinating efforts during and after flood events to ensure public safety and expedite recovery and rebuilding efforts.


Both GIS and Floodplain Administration play critical roles in managing natural resources, planning sustainable communities, and protecting against natural disasters like floods. GIS provides the technological backbone for analyzing and visualizing flood risks, while Floodplain Administration ensures that appropriate measures are taken to mitigate and manage those risks effectively.
