Coastal Inundation Capability Framework

Global warming puts U.S. coastal communities at greater risk of flooding from higher water levels and more severe storms. These communities need science-based information and services to help guide and inform their adaptation decisions. A new NOAA report, titled Coastal Flooding and Inundation Information and Services at Climate Timescales to Reduce Risk and Improve Resilience, proposes an enhanced federal capability to provide authoritative data, products, and services that quantify and communicate the risk of subseasonal-to-centennial coastal flooding and inundation for the United States and its territories. The report outlines a “whole-of-government” approach—aligning NOAA to work with Federal, public and private sector partners—to leveraging and advancing our Nation’s investments in research and development, data, products, and services.

A Federal Capability for Coastal Flooding and Inundation Information and Services at Climate Timescales to Reduce Risk and Improve Resilience

The Challenge

U.S. states and territories are increasingly at risk of coastal inundation from rising seas, changing Great Lakes water levels, and more frequent and intense storms as our climate changes.


NOAA envisions a centralized, integrated, operational framework of coastal inundation information and service delivery.


The envisioned capability will produce and deliver authoritative, easily accessible data and products complemented by tools, applications, and decision-support services that are nationally consistent and that enable all communities to advance the resilience of the Nation to coastal inundation now and in the future.

Looking Forward

To enact the envisioned comprehensive suite of coastal inundation at climate timescales services, the following steps are necessary:

  • Convene Federal collaboration and pursue partnerships
  • Develop implementation plans
  • Inform Federal policymakers
  • Inform the Federal budget process
  • Inform Federal policies
