AFFORDABLE HOUSING AT RISK: Threats from Coastal Floods and Sea Level Rise

The document highlights that Louisiana's affordable housing stock is the 8th most vulnerable in the United States, with projected increases in units exposed to coastal flooding by 2050.

• Louisiana's affordable housing stock is ranked as the 8th most vulnerable in the United States regarding units at risk of future coastal flooding.
• Currently, 214 affordable housing units in Louisiana are exposed to coastal flooding risk. By 2050, this is projected to increase to 685 units, representing a 220% increase compared to the year 2000 and affecting 0.6% of the state's affordable housing stock.
• Specific Louisiana cities are projected to see significant increases in exposed units by 2050; for example, Slidell is projected to have 22 units with four or more flood-risk events per year, and Luling is projected to have 72.
• Affordable housing is generally more susceptible to flooding because it is often older, of lower quality, and lacks resilience features such as flood-proofing, backflow prevention valves, or off-grid energy.
• Nationally, there is a shortage of over 7 million affordable rental units, with only 35 units available for every 100 extremely low-income renters, affecting all 50 largest metropolitan areas.
