Stormwater Controls-Additional Resources
The following resources may be helpful for permittees when considering design capacity of stormwater controls.
EPA
- Indicator View Mapper
This tool provides insight into observed changes in temperature, precipitation, storms, floods, and droughts.
Federal Emergency Management Agency (FEMA)
- National Risk Index (NRI)
The National Risk Index (NRI) is a new online resource from FEMA that analyzes risk factors for 18 natural hazards by defining risk as the product of expected annual loss (EAL), social and community vulnerability. - Preliminary Flood Hazard Data
Preliminary flood hazard data provide the public an early look at the projected risk to flood hazards. Preliminary data may include: new or revised Flood Insurance Rate Maps (FIRM), Flood Insurance Study (FIS) reports, and FIRM Databases. - National Flood Hazard Layer
National Flood Hazard Layer is a geospatial database made from effective flood maps and Letters of Map Change (LOMC). - Hazus
Hazus is a nationally available methodology that models potential losses from earthquakes/tsunamis, floods and hurricanes. Hazus uses GIS technology to estimate physical, economic, and social impacts of these hazards.
National Oceanic and Atmospheric Administration (NOAA)
- U.S. Climate Resilience Toolkit
Provides steps for users to understand and assess resilience, case studies, tools, training, and observed and projected climate data. Includes two mapping tools to support users understanding exposure to past and projected conditions, including:- Climate Mapping for Resilience and Adaptation shows and assesses climate-related hazards (i.e., extreme heat, drought, wildfires, flooding, and coastal inundation) based on modeled history and projected time periods.
- The Climate Explorer Tool provides interactive graphs and maps of past and projected climate data by county in the U.S.
- National Precipitation Frequency Standard
Provides precipitation frequency estimates and associated information.- NOAA Atlas 15 is currently being updated and will be the first iteration that will (1) develop precipitation frequency estimates for the entire United States and its territories, and (2) update the NOAA Atlas 14 precipitation frequency standard while accounting for changing long-term weather patterns. For more information, see NOAA Atlas 15 Information webpage.
