Who Gets Protected First? The Flood Money Debate
A city only has so much funding available to support flood mitigation projects, so they often have to prioritize which communities to aid. What sorts of neighborhoods are prioritized and why?
Imagine Harris County has a $50 million budget to build flood mitigation infrastructure this year, but two different neighborhoods need it immediately. Neighborhood A (River Oaks) has 10 large homes that are at risk of flooding, meaning $20 million in potential property damage. Neighborhood B (Kashmere Gardens) has 100 modest homes that are at risk, meaning $10 million in potential property damage. If Harris County chooses which community to build infrastructure for based purely on protecting the highest dollar value, Neighborhood A wins. If it chooses based on protecting the most people, Neighborhood B wins. The issue is, the former option is favored the majority of the time, leaving the modest community vulnerable to flood risk.
Municipal infrastructure projects typically rely on a traditional Cost benefit Analysis, or CBA. The Benefit-Cost Ratio is equal to the Total Dollar Value of Damages Prevented over the Cost of the Project. This means that spending $10,000 to protect a $100,000 home would yield a ratio of 10:1, as opposed to protecting a $20,000 home, with a ratio of 2:1. Since the first ratio is more favorable for the county, it typically tends to aid the higher income households.
So what was done to mitigate this issue? Harris County adopted an Equity Prioritization Framework in 2022. Following the 2018 voter-approved flood bond, this framework incorporates the CDC Social Vulnerability Index to better represent the danger that lower income households face due to flood risks. It takes into account household income, access to personal vehicles for evacuation, language barriers and insurance coverage, and housing density and age of structures. The change places a greater emphasis on the number of people benefitted and combats the social inequity present in many Houston communities. It is even ranked top 20 nationwide for using federal American Rescue Plan Act funds fairly. Despite the positive impact of the new framework, there remains core policy tension to be addressed.
For one, higher-value properties have a more significant contribution to the county's tax pool, leading taxpayers to argue that their tax dollars should prioritize their own neighborhoods. Moreover, the 2022 reform removed partnership entirely to support areas that not able to meet Federal benefit-cost thresholds used to determine funding eligibility. Doing so means that the county now has to self-fund more of these projects, stretching local bond dollars thin. So what should be done? Firstly, Harris County Flood Control District, or HCFCD, should publish an upstream and downstream economic impact statement for major bond projects. If a project builds a retention basin in a lower-income area, that water drains away faster from upstream neighborhoods as well. By illustrating this, higher-income taxpayers can be shown that fixing downstream choke points is the only way to keep their own streets from backing up. Additionally, Harris County can issue Environmental Impact Bonds for nature-based retention projects. This way, private impact investors supply the upfront capital, and the financial risk of construction delays is transferred.
