From Patch.com (Amber Fisher):
A new report from the First Street Foundation provides a national analysis of flood risk in states and cities across the United States, including in Colorado.
The nonprofit, dedicated to the research and development of flood prevention, released a model that allows users to assess flood risk in the past, present and future at the individual property level by location. The risk assessment takes into account sea-level rise, rainfall and flooding along smaller bodies of water.
The new in-depth report estimates that 14.6 million properties across the United States are at substantial risk of flooding, which is a staggering 5.9 million more properties than the Federal Emergency Management Agency (FEMA) shows on federal government flood maps…
When looking at all levels of flooding risk in our state, the data shows 200,400 properties at any type of risk over the next 30 years. Of these, 16,900 are categorized as facing almost certain risk.
Here are the cities and towns in Colorado that have the highest number of properties at risk of flooding.
Colorado Springs: 15,440 properties in 2020 Denver: 10,136 properties in 2020 Fort Collins: 4,559 properties in 2020 Aurora: 4,058 properties in 2020 Longmont: 4,023 properties in 2020 Boulder: 3,237 properties in 2020 Arvada: 2,730 properties in 2020 Loveland: 2,169 properties in 2020 Lakewood: 2,069 properties in 2020 Greeley: 1,885 properties in 2020
Denver will see the most significant increase in flood risk over the next 30 years, according to the data.
