Purpose

Sea level rise (SLR) will increases severity and frequency of coastal flooding, posing enormous socioeconomic implications in coastal cities. The data provide current and future coastal flood risks to assets in twenty coastal cities in the U.S. under 3 SLR levels.

Description

Average Annual Risk (AAR) of exposure to minor and extreme coastal flooding were calculated by interaction of flood frequency and property exposure values at risk. A nonstationary Mixture Normal-GPD probability distribution was used for flood frequency analysis. A cumulative properties exposure values correspond to water level above mean higher high water (MHHW) from risk finder tool (https://riskfinder.climatecentral.org) provided by Climate Central was used as an estimation of property exposure value.
