Precinct 1 Commissioner Rodney Ellis has placed an item on the Commissioners Court agenda for 1/10/23 with far reaching ramifications for flood control in Harris County. It would change the way every future project is prioritized using a formula that gives almost half the weight to population and building density. Meanwhile, it ignores the amount of damage, severity of flooding, danger to infrastructure, historical underinvestment, and the difficulty of accurately estimating population in flood zones. Ellis’ recommendation could be used to permanently deny projects to heavily flood-damaged areas like Lake Houston.

Text of Motion

In Agenda Item #250, Ellis seeks: “Request for approval to direct the Harris County Flood Control District (“District”) to assign prioritization scores using the adopted 2022 Prioritization Framework for the Allocation of Funds from the Harris County Flood Resilience Trust to all new flood risk reduction projects funded by the District when requesting Commissioners Court approval to initiate the project, and to transmit those scores as quartiles to Commissioners Court.”

So what is that framework and why do we need it?

History of Recent Efforts to Prioritize Projects

Before the 2018 flood bond, Harris County flood control looked primarily at clusters of repeat damage to define and prioritize projects. That damage also formed the basis for obtaining partner funding in many cases.

However, when the perpetually underfunded Flood Control District received the huge infusion of cash from the 2018 flood bond, a problem arose. Which of the many worthy projects would be launched first? There simply weren’t enough qualified contractors to handle all needs simultaneously.

The text of the 2018 flood bond approved by voters contained a sentence that said, “…Commissioners Court shall provide a process for the equitable distribution of funds…” (See Paragraph 14-G). That became the key to the answer…with some verbal legerdemain by Ellis that turned “distribution” into “prioritization” and “equitable” into “equity.”

2019 Equity Prioritization Framework

In 2019, Ellis proposed (and the Court adopted) the “Prioritization Framework for the Implementation of the Harris County Flood Control District 2018 Bond Projects.” This framework ranked projects with a multi-factor index using the following weights:

• 25% Flood Risk Reduction
• 20% Existing Conditions (Drainage Level of Service)
• 20% Social Vulnerability
• 10% Project Efficiency
• 10% Partnership Funding
• 5% Long Term Maintenance Costs
• 5% Minimizes Environmental Impacts
• 5% Potential for Multiple Benefits
• Total 100%

Commissioners, including Ellis, repeatedly affirmed their intent to complete all projects originally identified as part of the bond. The framework simply prioritized their start dates.

Commissioners also talked a lot about prioritizing “the worst first.” It was a nice sound bite, but never defined. Were the worst areas those with the most damage, deepest flooding, poorest residents, highest risk, or some combination of the above? Notice that the formula above omits flood damage, the traditional way of prioritizing funds and “ground-truthing” flood-risk estimates.

At this point, all of the projects in the bond have started. Their natural lifecycles and complexity will determine their order of completion. So, the debate has shifted from the flood bond to other sources of funding and future projects.

2021 Changes Applied to Flood Resilience Trust

In 2021, Commissioners created a Flood Resilience Trust using Toll-Road funds to backstop potential shortfalls in flood-bond partner contributions. The weighting used to allocate funds from the Trust changed significantly.

• 25% Structures Benefitted
• 20% Flooding Frequency
• 20% Social Vulnerability
• 10% Cost Per Structure
• 10% Partnership Funding
• 5% Maintenance Cost
• 5% Environmental Impact
• 5% Secondary Benefits
• Total 100%

Flood Control used this formula only to prioritize the use of backstop funds in the Trust. Note this version of the formula eliminated both damage and risk reduction from consideration.

2022 Changes

In April, 2022, Commissioners modified the 2021 weights within the Prioritization Framework – still only for Flood Resilience Trust Funds – as follows:

• 45% Project Efficiency
  • 15% Resident Benefits
  • 30% Structure Benefits
• 20% Existing Conditions
• 20% Social Vulnerability Index
• 5% Long Term Maintenance Costs
• 5% Minimizes Environmental Impacts
• 5% Potential for Multiple Benefits

This 2022 formula omits consideration of damage, risk reduction and partnership funding. But it gives weight to population density (project cost divided by # residents benefitted). This 15-page PDF explains how projects are scored within each category above.

2023 Proposal

Commissioner Ellis now proposes applying the 2022 Resilience Trust formula to ALL FUTURE HCFCD PROJECTS.

Problems with Proposal

Flood Control would now use Ellis’ formula to decide which projects make the list, not just which go first.

Thus, the so-called “equity” formula once used to schedule projects could now be used to eliminate projects altogether.

Two thirds of the weight goes to density and social vulnerability. Only 20% relates to flooding.

The projects most likely to be eliminated would be outside the Beltway – in less dense areas that have traditionally received the least funding. In a post-bond, financially constrained environment, the weight given to density will put every project outside the Beltway at a disadvantage.

But the Ellis formula has many other problems, too. It:

1. Does not differentiate between types of structures while giving them almost a third of the weight. Thus, a mobile home counts for as much as a hospital or college.
2. Gives no weight to protecting critical infrastructure such as bridges, hospitals, grocery stores, wastewater treatment plants, etc. 
3. Omits actual damage from consideration, which “ground-truths” risk assumptions (see Existing Conditions, Page 6).
4. Eliminates consideration of partnership funds, which have provided almost one third of HCFCD funding since 2000.
5. Gives 20% weight to social vulnerability, but ignores the severity of flooding. Thus a low-income home with one inch of flooding counts as much as an entire condo complex swept away by 22-foot deep floodwaters. 
6. Makes awards more subjective because HCFCD has no way of estimating how many people live in apartment buildings or homes. HCFCD can count buildings in satellite photos, but the number of residents benefitted will always be a guess. Census tracts do not follow floodplain boundaries.
7. Undermines efforts to prevent flooding, as opposed to correcting it after people are damaged. Prevention, such as HCFCD’s Frontier Program, is always more cost effective in the long run.
8. Forces Flood Control to judge projects before the District has engineering and cost data in hand that would help determine whether the projects are worth pursuing. That’s because “ALL FUTURE PROJECTS” include preliminary engineering projects.

Suggestions For Improvement

Below are several suggestions to improve the formula.

1. Define “worst first.” While the sentiment is noble, in practice, the term has no practical definition. (Ditto for equity.)
2. Incorporate measurements for severity of flooding and amount of damage. These really define worst.
3. Prioritize critical infrastructure such as bridges whose loss can jeopardize the economic vitality of the region.
4. Include partnership funds. They help stretch flood-mitigation tax dollars by almost a third. Even if people sometimes must wait longer to line up partner funding, partner funding helps more people in the long run.
5. Acknowledge that HUD dollars go disproportionately and preferentially to Low-to-Moderate Income neighborhoods.
6. Publish level-of-service data, used in the “existing conditions” calculation, for all streams in the county. It seems to be secret. I’ve been trying to get it for a year. Keeping it secret undermines trust in government. How do we know money is really going to the areas with the greatest risk?
7. Publish results of the new prioritization index periodically, so we can see which projects are being eliminated and why. And so we can understand why 18 of the 20 currently active capital improvement projects are in Precincts 1 and 2.
8. Publish a 5-year Capital Improvement Plan similar to the City of Houston. Let people see what is coming, when, and for how much. That way we can hold HCFCD and Commissioners accountable. Plus, we can see their “formula” in action.
9. Acknowledge where money has really gone historically.
10. Be fair to all. The proposed formula is like playing cards with a stacked deck.
