Addresscloud US Flood

1. What is it?

Addresscloud US Flood (usafld) is a comprehensive dataset that provides detailed flood risk information across the United States. It integrates data from multiple authoritative sources to offer insights into flood hazards at the building level, enabling users to assess and manage flood-related risks effectively.

2. How can I use it?

This dataset is valuable for:

• Insurance Underwriting: Evaluating flood risk to determine appropriate coverage and premiums.
• Real Estate Analysis: Assessing property flood risk for investment and development decisions.
• Emergency Planning: Identifying high-risk areas to enhance disaster preparedness and response strategies.
• Regulatory Compliance: Ensuring adherence to floodplain management regulations and building codes.

3. How is the data created?

The dataset is compiled by integrating information from:

• FEMA National Flood Hazard Layer (NFHL): Provides flood zone designations and floodplain boundaries.
• USGS National Hydrography Dataset: Offers detailed hydrographic data, including water bodies and flowlines.
• NOAA SLOSH Model: Supplies storm surge data for coastal flood risk assessment.

Addresscloud processes and harmonizes these data sources to deliver accurate and up-to-date flood risk information at the building level.

4. Are there any limitations?

While Addresscloud US Flood offers extensive flood risk information, users should be aware of the following:

• Data Currency: Annual updates may result in a lag between current floodplain changes and the dataset.
• Model Limitations: Predictive models may not account for all variables influencing flood risk, such as recent land development or climate change effects.
• Resolution Constraints: While data is provided at the building level, some attributes may be generalized from broader datasets.

5. What data points are available?

The Addresscloud US Flood dataset includes, but is not limited to, the following attributes:

• Flood Zone Designation: FEMA flood zone classifications (e.g., Zone AE, Zone X).
• Base Flood Elevation (BFE): Elevation at which there is a 1% annual chance of flooding.
• Distance to Nearest Water Body: Proximity to rivers, lakes, or coastlines.
• Storm Surge Risk: Likelihood of flooding due to storm surge events.
• Historical Flood Events: Records of past flooding incidents at or near the property.
