EPA Researchers Are Providing Tools And Resources To Prepare Communities For Climate Change And Extreme Storms
By U.S. EPA
Each season brings expected changes to the weather. But with climate change and the warming of the atmosphere, weather patterns are becoming less predictable with more heat waves, and increased severity of super- and local- storms.
EPA scientists are investigating the increased occurrence and intensity of extreme precipitation events, which are defined as days with precipitation in the top one percent of all days with precipitation, according to the U.S. Global Change Research Program. Many parts of the country have experienced these changes already with storms that bring high accumulations of rain or snow, resulting in flooding and threats to public health and property.
Resilient water infrastructure design brief
Format
Objective: Resilience
A 2019 report by the World Bank, entitled “Lifelines: The Resilient Infrastructure Opportunity,” estimated that low- and middle-income countries lose $390 billion each year to disruptions of power, transportation, water, and telecommunications services caused by natural hazards (World Bank 2019). The disrupted services are typically delivered through large networks that are vulnerable to natural hazards over a large area. Improving the resilience of those networks would cost about 3 percent of their capital investment, but the avoided disruptions would save quadruple that amount. In other words, every dollar spent to improve resilience would avoid four dollars in costs owing to service disruptions. The cost reduction associated with spending on resilience is estimated to be $4.2 trillion over the useful life of new infrastructure (World Bank 2019).
