How Does Houston Pay to Stop Floods?

Right now, Houston spends a lot of money after a storm hits to repair damage. What can the city do to save that money and prevent such damage from happening in the first place?

Flooding in the urban area of Houston after Hurricane Harvey

There are two major types of spending used to address the destruction inextricably linked with the type of heavy storms that Houston is prone to: proactive and reactive. If you buy a phone case for $40 to prevent your screen shattering from a drop, that would be proactive. On the other hand, if you wait until it shatters, you can pay $200 to fix it as a reactive solution. Similarly, Houston's reliance on funding after a disaster occurs leads to a reactive funding trap, where the city loses climate-resilience as it must wait for emergency measures post-hurricane.

The city must work to transition to proactive financing measures to ensure both economic and environmental fortitude. So how should it go about doing that? Let's first learn where Houston's flood money comes from. It currently receives funding from three major sources: local taxes and bonds, federal government grants, and monthly drainage fees.

Local taxes and bonds:

• This source acts as a sort of credit card, where the city is able to pay for projects immediately

• Houston asks voters to approve big loans, or bonds, to build the flood-resilient architecture or damage protection they need

• Harris County has a $2.5B Flood Control Bond

• The downside of this is that it increases local public debt burden and relies heavily on taxpayer approval

Federal government grants:

• This source acts as the emergency backup after destruction has occurred

• For example, when a major storm happens, Washington D.C can send billions of dollars to help fix up the city

• Though, due to the processing time of the paperwork, citizens can be waiting for years unprotected for the funding to arrive for project deployment

Monthly drainage fees:

• This source acts as a sort of allowance, where a little money is gained at a time

• By adding fees to a resident's water bill, neighborhood drains can be cleared out and flooding can therefore be reduced

• While the flow of incoming money is steady and reliable, it is marginally helpful considering how small the amount of collected money is

According to the National Institute of Building Sciences framework, every $1 spent on proactive flood mitigation saves an average of $6 in future recovery costs. This return on investment, or ROI, proves that longterm infrastructure such as bayou expansion or implementation of green spaces is beneficial for both the environment as well as saving taxpayers' valuable money. One major financing proposal that would help Houston make the transition to proactive spending is Environmental Impact Bonds. Instead of reliance on regular government loans, the city can pair up with private investors to maximize funding and minimize taxpayer expense and time before project deployment. For example, private investors can give Houston the money to build a flood mitigation tool such as a park that absorbs rainwater. If the park performs well and works to prevent flooding, then the investors are paid back with a bonus (the money that the city saved from property destruction from a storm). If the park does not function as intended, then taxpayer money isn't wasted. Overall, implementation of Environmental Impact Bonds would transform Houston into a far more climate-resilient city because of its longterm benefits and proactive spending. With continued support and awareness, Houston can become a greener city for all. Follow along with Bayou Barrels to see how you can make a difference.
