Introduction to Flood Impact Analysis

Flood Impact Analysis can be used to analyze the impact of flooding on critical infrastructure and share flood impact maps with internal and external stakeholders.

In recent years, the frequency and intensity of flooding disasters has increased and so has the impact on local communities. Over the last decade alone, floods have caused billions of dollars in property damage. As a result, local governments must be better prepared for flooding events so they can reduce the risk of property loss and protect human life.

When heavy rainfall or storm surges are predicted for a community, rich geospatial data (for example, flood depth, ground elevation, and public assets) and spatial analysis is used to analyze the impact of flooding and produce a series of flood impact maps. Flood impact maps communicate the extent of flooding events and provide valuable information about the affected areas and the potential risks and hazards to government officials and the public. They also help emergency management agencies develop mitigation strategies, plan road closures, and prioritize evacuation areas. Any delays in the production of flood impact maps could impact a community’s emergency response plans and reduce its resiliency to flooding events.

The Flood Impact Analysis solution delivers a set of capabilities that helps you develop localized flooding scenarios and visualize the impact of flooding on public infrastructure and critical facilities.

Release notes

The following are the release notes:

Version	Description
1.6 (Nov 2024)	The Flood Impact Analysis ArcGIS Pro project now includes the following enhancements: It now supports ArcGIS Pro 3.4. New task steps have been added to verify that all user data is in the same coordinate system prior to completing the analysis. The Getting to Know Flood Impact Analysis and How to Use Flood Impact Analysis task items have been combined into a single task item. An update to the Create Flood Depth Geodatabase and Create WSE Geodatabase tools included with the ArcGIS Pro project resolves a reported issue to allow users to save to file paths with space in the folder name (BUG-000139874).
1.5 (Nov 2023)	A new Flood Impact Analysis ArcGIS Pro project to support ArcGIS Pro 3.2.
1.4 (Jun 2023)	A new Flood Impact Analysis ArcGIS Pro project.
1.3 (Mar 2023)	A new Flood Impact Analysis ArcGIS Pro project to support ArcGIS Pro 3.1 and updates to the tasks related to defining Z coordinates and elevation rasters to scenes.
1.2 (Jul 2022)	A new Flood Impact Analysis project to support ArcGIS Pro 3.0. Resolved an issue with the Create 3D Flood tool that would cause it to fail on larger data sets.
1.1 (Jun 2021)	Resolved an issue when a meter-based coordinate system is used with the Windows language set to other than English.
1.0 (Nov 2020)	First release of Flood Impact Analysis.
