Flood Bond Progress: 35% Time Elapsed, 19.4% Money Spent

A February update by Harris County Flood Control District (HCFCD) on the status of the 2018 Flood Bond showed that 35% of the way into the program (42 out of 120 months), 19.4% of the funds from all sources (including grants and partnerships) had been spent. That percentage was based on $967 million spent out of $5 billion projected.

Cost of Studies vs. Construction

While one percentage seems to lag the other by a factor of almost 2X, HCFCD estimates it is virtually on schedule. That’s because studies conducted up front cost far less than construction. And only 44 of 181 Bond program projects have entered construction at this point (24%). As more projects enter the construction phase, the pace of spending should accelerate.

From High-Level Summary to Nitty-Gritty Detail

The 13-page update features three major sections:

  • Summary statistics for the entire bond program
  • Project flow charts showing status of all projects
  • Watershed maps showing the amount spent to date; funded to date; and the values of all active maintenance and capital projects.
Spending by watershed on HCFCD flood bond projects through the end of February 2022.

Skewed Distribution of Capital Improvement Projects

Out of 75 active capital improvement projects, I counted only 13 in Precincts 3 and 4 which have Republican commissioners. Those contracts totaled only about $82 million out of about $249 million. That’s a testament to how thoroughly the Democrat-controlled Commissioners Court has relentlessly tweaked the Equity Prioritization Framework. For instance…

In northeastern Harris County, the update shows only two active capital projects valued at a whopping $1,000 each.

Of the 13 active capital projects in Precincts 3 and 4, six are E&R contracts valued at just $6,125 altogether. See page 13. The report lists no E&R contracts in Precincts 1 and 2.

Excavation and removal contracts let contractors sell dirt they remove from a site as a way of making back their normal profit margin. They’re a good deal for taxpayers as long as the demand for fill dirt remains high. But if demand slows, excavation progress could stall. In other words, they come with uncertainty attached.

Breakdown of San Jacinto Watershed Projects

Of ten bond projects listed in the San Jacinto Watershed, schedules show:

  • 4 in the feasibility-study phase
  • 2 in preliminary-engineering reviews
  • 1 in construction
  • 3 not yet started.

The February report did not address a method of distribution for $750 million allocated by HUD and the GLO for flood mitigation to Harris County. The award happened on March 18, 2022 and will likely be covered next month.

How Do You Define “Worst First”?

In the rush to mitigate flooding after Hurricane Harvey, most people agreed that we should attack the areas with the worst flooding first. While almost everyone agreed with the “worst first” mantra, no one defined it – until after the flood bond passed.

Alternative Ways to Define “Worst First”

How would you define the “worst” flooding? The area with the:

  • Most flooded homes?
  • Most frequent flooding?
  • Most damage in dollar terms?
  • Largest population living in a 100-year floodplain?
  • Most low-to-moderate income residents who can least afford to fix their homes?
  • Largest minority populations?
  • Highest Social Vulnerability Index (SVI)?
  • Most damage to infrastructure (bridges, hospitals, grocery stores, schools, sewage treatment plants, etc.)?
  • Highest water above the tops of banks in a widespread storm like Harvey?

You could make valid arguments for each. And people have – almost from the day the flood bond passed – as they fought for more funding for their watersheds.

Least Considered Alternative

But the one I have heard talked about the least is the last one: highest water above tops of banks. Surely, the depth of a flood must count for something. It affects the ability to evacuate and rescue people. It puts lives at risk. Can destroy infrastructure. Spread sewage. Increase erosion. Even cause rivers to migrate. And sweep whole apartment buildings into rivers.

Yesterday, as I reviewed a doctoral thesis from a student at the Colorado School of Mines, I saw a graph that compared the height of the Harvey flood at the San Jacinto West Fork and US59 to other rivers/streams in the region. The West Fork flood towered above the others. So it made me wonder. How did the flood at that location compare to other streams and bayous in Harris County?

How to Determine “Feet Above Flood Stage”

There’s an easy way to find out. The Harris County Flood Warning System contains all the pertinent information.

  1. Go to the home page.
  2. Click on a gage.
  3. Click on the “For more information” link in the pop-up box.
  4. On the new page (dedicated to historical information about that gage), click on the stream elevation tab.
  5. Note the “flooding likely” elevation. This roughly coincides with the top of bank, though banks can vary slightly.
  6. Scroll down to the bottom of the page and note the elevation of the flood at that location during Hurricane Harvey.
  7. Subtract the “flooding likely” level from the Harvey level, to determine the feet above flood stage in Harvey.
  8. Click on the drop-down box with the gage information to compare the same stats for additional gages.

North Harris County Had Highest Floods

This morning, I compiled the data for 33 gages. The chart below shows what I found. Of the gages I sampled, the four highest floods all occurred in the upper San Jacinto River Basin: West Fork at 59, Spring Creek at 45, Cypress Creek at Cypresswood, and West Fork at 99. Also note the preponderance of high water along Greens Bayou at numerous locations.

Data compiled from Harris County Flood Warning System using the technique described above.

Limitations of Measure

“Feet above Flood Stage” by itself won’t tell you which area had the worst flooding during Harvey. It’s just one measure. You must consider other factors, too, such as those listed above.

But this chart sure makes it hard to ignore the fact that something is happening in north Harris County to exacerbate flooding. I’ve chronicled many of those things in the pages of this website: sand mining, development, rapid growth, impervious cover, loss of wetlands, lack of detention ponds, lax regulation/enforcement and more.

One must also acknowledge the role that topography plays in a chart, such as this. A narrow floodplain with steep banks can force water higher. A wider floodplain through a flat area allows water to spread out, lowering the height of floodwaters.

Variations in rainfall across an area can also skew results.

And finally, I didn’t click on every gage in the region. There are hundreds. You wouldn’t have been able to read the chart because the type would have been so small. So investigate on your own and let me know what you find.

Need for Active Discussion/Debate in Upcoming Elections

The Harris County Community Flood Resilience Task Force just voted to change the way “worst first” is calculated – again! The highest correlation between funding and all of the other factors I have evaluated is now with low-to-moderate-income population. It’s not with damaged structures, dollar damage, watershed size, or population density.

If you want to ensure that outlying areas get their fair share of flood mitigation dollars in the future, you need to demand them when you go to the polls this fall.

Chain Link Fencing at Laurel Springs RV Resort Would Not Meet Exxon Land Development Commercial Guidelines

Since my last post on the Laurel Springs RV Resort, contractors have erected approximately 2000 feet of chain link fence, much of it within feet of Laurel Springs Lane. Exxon Land Development Commercial Development Guidelines generally prohibited chain link fencing except in rare instances where the fence was “not visible from the street or adjacent property.” See Section II-9-3 Screen Walls and Fencing and the pictures below.

Because Exxon never owned this property, it was not subject to the deed restrictions that apply to Kingwood. So I’m not alleging anything illegal. However, the developer has disregarded community norms. Those deed restrictions give the Kingwood Area its distinctive character. Disregarding them has not endeared the developer to neighbors.

Other “Improvements”

The developer also made several other “improvements” in the last few days. He has:

  • Removed more trees
  • Brought in more dirt to raise the property even higher above Lakewood Cove
  • Approximately doubled the area covered by concrete
  • Finally erected a silt fence on the west side by the utility corridor, five months into construction
  • Hydroseeded the south bank of the detention pond and northern part of Edgewater Park where they cut down trees…after severe erosion caused Harris County to threaten a lawsuit.

However, there still appears to be no effort to replant the trees they cut in Edgewater Park. Nor have they placed permanent pumps to drain the retention pond; they’re still attempting to do that with portable pumps.

Photos Taken 3/28/2022

Here’s how the site looked tonight.

The amount of concrete virtually doubled. They poured the dark gray area in the foreground last Saturday. A swimming pool will go between the concrete and the building under construction.
More downed trees litter the northern part of the property. Trucks have been bringing in more dirt to fill in low spots which became apparent after last week’s 2″ rain.
That blue/green material is called hydromulch, also referred to as hydro seeding. Looking SE toward Edgewater Park.
Looking E toward Lakewood Cove and Laurel Springs Lane as crews finish spraying for the day.
The hydroseeding crews were pulling silty water from the detention pond to mix with their material, even as portable pumps attempt to drain the pond before the next rain arrives tomorrow night.

More about Hydroseeding

Contractors use hydroseeding to stabilize slopes and accelerate the germination of grass which can reduce erosion. Water, seed, and nutrients are mixed into a gelatinous material and sprayed onto the ground. The gelatin adheres to slopes and retains just enough moisture to help the seed take root. We should see grass start to grow within 5-10 days. Crews add colored dye to the mix to make it easier to see. That helps them spray it evenly.

Should Have Hydroseeded Earlier

After the a five-inch rain in January, the south wall of the detention pond started slumping into Edgewater Park. Sediment several inches deep fanned out into the wetlands of Edgewater for approximately 150 yards, according to the TCEQ. And Harris County issued its cease-and-desist letter threatening the developer with a lawsuit. Since then, the developer has spent much of the last month trying to move the pond wall back onto his own property. I imagine the contractor now wishes he would have hydro seeded earlier.

Chain Link Fence Disregards Community Norms

Assuming surveyors were accurate, the chain link fence should now identify the southern boundary of the RV resort. However, given the history of this project, that could be a big assumption.

Thankfully, at least the chain link fence does not have razor wire on top of it. Regardless, it has all the charm of the prison in Huntsville.

While you review the Commercial Development Guidelines on fencing, scan the rest of the guidelines, too. Especially the ones that talk about setbacks, construction fencing, parking, tree preservation and more. They will give you a greater appreciation for the care taken by thousands who came before the Laurel Springs RV Resort.
