Brief: Resilience Strategies for Flash Flooding

Created: 12/19/2018 - Updated: 7/18/2019


The United States is facing increasingly frequent and intense precipitation events and ever higher damages from flooding each year due to climate change and urbanization. Communities, counties, and states are responding by upgrading stormwater and sewage systems with a growing emphasis on strategies to become more resilient to flooding. This paper outlines resilience strategies for flash flooding, with an emphasis on riverine and precipitation-caused flooding. For each strategy, the paper will discuss primary and co-benefits, and associated costs. Costs and benefits will vary based on local conditions and climate projections. A case study of Philadelphia’s green infrastructure plan, Green City, Clean Waters, provides an example of an applied comprehensive green infrastructure plan based on a cost-benefit analysis. The paper concludes with high-level insights and a list of publications and interactive tools available to start building resilience to flooding.
