Differences in Ways County, State Propose Ranking Flood Projects

The Texas Water Development Board is seeking public comment on its plan to allocate $375 million in funding from the State’s flood infrastructure fund for the 2024-25 state fiscal year.

That prompted me to compare the TWDB and Harris County plans for ranking flood projects. The differences remind me of how the scoring systems favor certain projects in some areas and not others.

Harris County and the Texas Water Development Board (TWDB) use distinctly different priorities when considering which flood-mitigation projects to fund.

The biggest differences have to do with the weights given to severity of flooding, protection of infrastructure, social vulnerability and maintenance costs.

The state also uses “benefit/cost ratios” much like the federal government. The county, however, uses a measure called “project efficiency,” which is related but slightly different.

Differences in Ranking Projects

Here is the most recent prioritization framework that Harris County adopted in 2022 and again in 2023. And here is the draft “intended use plan” for the State of Texas 2024-25 Flood Infrastructure Fund.

Let’s look more closely at each plan and then examine their differences.

Harris County Prioritization Framework

Harris County examines:

  • Project Efficiency…
    • Using People Benefitted
    • Using Structures Benefitted
  • Existing Conditions
  • Social Vulnerability Index
  • Long Term Maintenance Costs
  • Environmental Impacts
  • Potential for Multiple Benefits

Each project is assigned a score for each criterion below ranging from 0 to 10. A score of “10” indicates the project fully met the criterion and a score of “0” indicates that it did not.

Summary of ranking matrix from page 4 of Harris County Framework. For explanations of scoring on each measure, see full document.

Proposed TWDB Matrix

The TWDB scoring matrix measures more factors and gives them different weights.

For larger, high res version and detailed explanation, see full plan.

The first thing you notice is that the table above is much wider and deeper than the County’s matrix. That’s because it lists evaluation criteria for different categories. And criteria sometimes change depending on the category.

Comparison of Differences

Social Vulnerability

Harris County gives 20% of all projects’ weights to social vulnerability. But the TWDB only gives it 5% weight. TWDB also uses social vulnerability as a tie breaker (see page 22).

Equity

Harris County has organized its flood-mitigation priorities since 2019 around equity. The proposed TWDB plan does not mention the word.

Efficiency

Harris County measures the efficiency of removing people and structures from the 100-year floodplain. The County defines efficiency as the cost of the project divided by the number of people or structures benefited. It gives them 45% weight within the final score.

TWDB also measures the number of people and structures removed from the 100-year floodplain. But unlike the county, it factors in critical facilities, the number of low water crossings, and miles of roads removed from the 100-year floodplain. Combined, they represent 55% of the weight. TWDB does not weigh cost against these measures at this point in its scoring matrix. However, it separately gives 2.5% weight to benefit/cost ratios.

Flood Risk

Harris County does not directly incorporate flood risk in its evaluations. It uses a proxy called “Existing Conditions” and gives it 20% weight. Existing Conditions measures the level of service provided by a detention basin or a channel. For instance, one with a 2-year level of service floods in a 2-year storm. One with a 25-year level of service floods in a 25-year storm, etc.

TWDB does not directly measure flood risk either. Rather it measures the number of structures, people, critical facilities, low-water crossings and road miles inside the 100-year floodplain. It’s a measure of what is “at risk.” These measures collectively add up to 100% of the score for a flood-management evaluation and 60% of the score for a flood-management strategy.

Severity

Harris County gives no weight to the severity of flooding. TWDB does. TWDB measures both the average depth of flooding in a 100-year storm and the percentage of a community’s population exposed to a 100-year flood. Together, they can account for 10% of a project’s total score.

Critical Facilities

Harris County does not differentiate among structures removed from a 100-year floodplain. But TWDB recognizes critical facilities. Such facilities could include sewage and water treatment plants; bridges; schools; hospitals; police and fire stations; and more. These affect entire communities, not just individuals.

Maintenance Costs

Harris County projects maintenance costs and gives them 5% of the weight. TWDB does NOT consider costs associated with current or future operations and maintenance activities.

No Right or Wrong Way

Neither the TWDB plan, nor the County’s plan is right or wrong. Their weights reflect the needs of different people and different organizations in different places. For instance, the state is not involved in maintenance, but maintenance historically has consumed as much as 50% of Harris County Flood Control District’s budget. So it makes sense for the county to prioritize low maintenance costs.

However, I would observe that Harris County could borrow some ideas from the state, such as incorporating measures for severity of flooding, protection of life, and protection of critical facilities. The areas that had the deepest flooding and the highest loss of life during Harvey have received little flood-mitigation assistance from Harris County compared to poor areas.

What Do You Think?

TWDB seeks public comment on its proposed plan by January 1, 2024. What do you think? Based on your flood experience, do you think TWDB could do something better? Let them know.

Their plan includes more information than shown above. For instance, it also includes information on eligibility, minimum standards, program timeline, and financial assistance categories.

If you wish to comment email FIF@twdb.texas.gov and specify in the subject line “FIF IUP Comments.” Should you have any questions, please contact the TWDB by emailing the same address.

How Kingwood Voted in Whitmire Win

In the 2023 runoff election for Mayor of Houston, John Whitmire won by a landslide. Kingwood voted for Whitmire at much higher rates than the city as a whole. He won 91.4% of the votes in Kingwood – a 10.6 to 1 margin of victory over Sheila Jackson Lee, compared to 1.9 to 1 for the City as a whole.

Most of Undecideds Sided with Whitmire

Whitmire enjoyed a 7% lead over Lee in early polls, but picked up most of the undecideds. He finished with a convincing 65.26% to 34.74% victory, not quite a 2:1 margin.

Citywide, Whitmire won by a margin of 60,275 votes. In Kingwood, he beat Jackson Lee by 8,734 votes – 14.5% of his citywide margin.

That’s remarkable for two reasons.

  • Kingwood has only 3% of the City’s population (about 70,000 out of 2.2 million).
  • Kingwood had 5% of the total voters in the runoff.

Among the City’s 1.2 million registered voters, turnout was a meager 16.92%. But among Kingwood’s 44,000 registered voters, turnout was 23.86% – 7 percentage points higher.

Ten of Kingwood’s 12 precincts had turnout in the top quintile of all precincts.

So, Kingwood had higher turnout than most areas and those who voted preferred Whitmire overwhelmingly.

Meaning of Whitmire Win

Whitmire ran a positive campaign focused on crime, the economy, drainage/infrastructure, city services and bringing Houston together.

Kingwood is traditionally Republican. Kingwood’s overwhelming endorsement of the moderate Democrat may herald a sea change in local politics. Here, in this election, in this place, at this time, voters buried partisan politics and reached across the aisle to support centrist viewpoints that benefit the majority.

Kingwood has 12 voting precincts.

It appears to me that Sheila Jackson Lee’s winner-take-all politics of polarization backfired on her this time. I haven’t yet had time to check other Republican-leaning areas, but in Kingwood, it seems that Republican’s arms didn’t stretch to her extremes.

The Candidate Now Has a Mandate

While Whitmire could have won the City convincingly without Kingwood, he won it dramatically with Kingwood. He will start the job with a broad mandate.

Whitmire still has huge challenges to face. Now comes the hard part of governing a city saddled with debt.

The good news as far as the Lake Houston Gates Project is concerned: funding comes mainly from outside sources and can only be used for gates, according to current Mayor Pro Tem Dave Martin.

And after 50 years in Austin, Whitmire knows how to work across the aisle and only Whitmire made flooding an issue in his campaign.

I hope Whitmire’s win ushers in a new era for the City that gives everyone a seat at the table, not just those on the far left.

Remember Flooding? Vote for Whitmire.

This is a week for good news and bad. Yesterday, we locked in another $50 million for the Lake Houston Gates Project. But one of the key people who helped us secure that funding is himself locked in a runoff election for City of Houston Mayor. And turnout so far has been abysmally low.

Whitmire Helped Secure $50 Million for Gates from State

More about the good news first. Yesterday, the Texas Water Development Board officially confirmed a $50 million grant to help build additional floodgates on the Lake Houston Dam. That will clear the way for final design, approvals and construction.

State Senator John Whitmire, candidate for City of Houston Mayor, helped secure that money. According to Mayor Pro Tem Dave Martin, who has shepherded the gates project since Hurricane Harvey, Whitmire reportedly talked several reluctant senators into supporting the grant. Whitmire has been in the Texas Senate for 40 years and sits on the Finance Committee.

So Whitmire already has some skin invested in the gates project. If elected Mayor, he could provide necessary consistency for the project as it moves forward during the next four years.

Martin also reminded me that future FEMA grants for Lake Houston will depend on a maintenance dredging program. So, we need a mayor who can work with the state legislature to help secure future dredging grants. And Whitmire has relationships with all the key players in Austin.

Turnout Abysmally Low

Now, for more on the bad news. Turnout in the Houston runoff election so far has been “sluggish” according to the Houston Chronicle.

I personally would call it “somewhere south of abysmal.” Only 131,887 people in a City with roughly 1.75 million adults voted early. So, less than 10% of Houston adults have voted so far in what could be the most consequential election of this generation!

Why Mayor is Crucial

After Harvey, the Lake Houston Area Task Force identified more gates for Lake Houston as one of the three most crucial projects to reduce flooding in the area. In case you’re new here, this is what the San Jacinto West Fork looked like during Harvey.

Looking south toward Humble along US59. Water here was more than 20 feet above flood stage, the highest in Harris County and knocked out the southbound bridge for almost a year.

The flood affected 16,000 homes and 3,300 businesses in the Lake Houston area. That included 44% of all the businesses in the Lake Houston Chamber and 100% of all the businesses in Kingwood Town Center, which still hasn’t fully recovered. At the time, many people said, “If it happens again, I’m leaving.” That said…

It will likely take four years to complete the gates – the entire term of the next mayor. We need a mayor who will remain committed to the project.

The Mayor has the power to prioritize the project…or not.

Only Whitmire Has Made Flooding an Issue

In that regard, Whitmire is the only candidate who made flooding a central element of his campaign.

This election could determine the future direction of our community and the City for decades to come.

Four 500-Year Storms in Eight Years

And lest you think a 500-year flood only happens once every 500 years, I would remind you that four hit this area in the last eight years: Tax Day, Memorial Day, Harvey, and Imelda.

We Have Power to Swing This Election

Now for the final piece of good news. So few people are voting throughout the City that Kingwood has the power to swing this election on Saturday.

Only 8,381 people have voted so far at the Kingwood Community Center – in a community of more than 70,000 people. While that’s one of the highest totals in the county, it still leaves the citywide outcome in doubt.

So please vote. Get your neighbors to vote. And get your neighbors to get their neighbors to vote. Etc.

When I voted early, I got to the polling place and back before my screen saver kicked in. It took less than 20 minutes round trip. With so much at stake, there’s just no excuse not to vote.

Voting Times, Places, Ballots, Etc.

Remember, races for several council positions and city controller remain open. View your sample ballot here.

Polls will open at 7AM and close at 7PM.

Vote at any of these locations.
