Big Stories to Watch in 2020

As we enter 2020, keep your eyes on these stories.

Elm Grove Lawsuits and Mitigation

In 2019, Elm Grove flooded twice with runoff from the Perry Homes/Woodridge Village development in Montgomery County. Hundreds of homeowners sued Perry Homes’ subsidiaries (PSWA and Figure Four Partners) and their contractors.

On 12/17/19, attorney’s for the plaintiffs filed a fourth amended petition. Since the original filing, plaintiffs have named Double Oak Construction and Texasite LLC as additional defendants.

The judge set a jury trial date for July 13, 2020. To date, Perry Homes has done nothing to reduce the threat of flooding from their job site.

*The 268-acres clear-cut acres that contributed to Elm Grove Flooding.*

That brings us to the subject of mitigation.

What can be done to restore the safety of residents?

Perry Homes has demonstrated no interest in reducing the threat to downstream flood victims.

Protecting homeowners will require massive intervention from an outside source. But who? And how?

Harris County Bond Fund Mitigation Projects

In 2019, Harris County Flood Control began work on 146 of 239 of the projects identified in their $2.5 billion flood bond.

Many of those projects required studies and partners. Three affecting the Lake Houston Area are:

*Many projects could actually enter the construction phase next year.*

Recommendations from each study should come out in 2020. Then many more projects will get underway.

Upstream Development

In 2019, we saw what upstream development did to homes in Elm Grove and North Kingwood Forest bordering Taylor Gully.

I recently learned of two new developments in the Ben’s Branch watershed.

A developer intends to build 18 acres of apartments where the woods adjacent to the new St. Martha Church now stand.
Another developer intends to build hundreds of homes on tiny lots on an 80-acre site just north of St. Martha’s.

These two projects represent dozens of others gobbling up farm and forest land in southeast Montgomery County.

*This drainage ditch feeds into Ben’s Branch at Northpark Drive. The 18 acres of trees on the other side of the ditch could soon become apartments.*

Businesses such as the St. Martha School and Kids in Action already flooded twice this year. So did dozens of homes along Ben’s Branch.

Additional upstream development has the potential to make flooding even worse. This is like death by a thousand cuts. Residents just don’t have the time or energy to monitor each development to ensure that owners follow rules and regulations for wetlands, floodplains, drainage, etc. Neither evidently does Montgomery County. Which brings us to…

Montgomery County Standards and Enforcement

Montgomery County competes for development by touting its lack of regulations. That’s a huge problem for downstream residents.

Montgomery County still bases flood maps on data from the 1980s.
Large parts of the county remain unmapped for flood hazards.
The County last updated its Drainage Criteria Manual in 1989.
Developers ignore many provisions within it.
County Commissioners voted to leave loopholes open that allow developers to avoid building detention ponds.
The County even paid an engineering company to investigate itself for its role in the Elm Grove Disaster.

You get the idea. If you thought some benign government entity watched over new developments to protect downstream residents, think again. Below you can see the 80-acre site I mentioned above.

*Source: USGS National Wetlands Inventory.*

Note how it was covered in wetlands. Developers did not ask permission from the Corps to remove them. They just decided on their own that they didn’t need to ask.

Below, you can see how virtually half the site is in a flood zone or floodway.

*Source: FEMA’s national flood hazard layer viewer.* *Brown = 500 year flood plain, aqua = 100 year, cross-hatched equals floodway*.

Here’s how it looks in Google Earth. Developers have already cleared the site.

Developers intend to build high-density homes in the floodplains. They will also build their detention pond in the floodway. Those hazard areas will likely expand when and if the County incorporates new Atlas-14 data into their flood maps.

*Layout for Brooklyn Trails development in Montgomery County*

None of this seems to bother the leadership of Montgomery County. And that’s a bigger problem than any one development.

In 2020, expect more focus on the decision-making process and decision makers who have created a permissive culture of indifference to flooding problems.

Sand Mines

Sand mines operate so closely to the San Jacinto that their walls frequently break and pour polluted process water into the drinking water for 2 million people. If they get caught, they pay a small fine and continue operating with impunity.

Left: Liberty Materials Mine in Conroe that undercut five pipelines carrying highly volatile liquids. Center: Triple PG mine in Porter where erosion during Imelda exposed one natural gas line and threatens 5 more HVL pipelines. Right: Another Liberty Materials mine that allegedly dumped 56 million gallons of white goop into the West Fork.

Upstream Detention

During Harvey, the release of 80,000 cubic feet per second from Lake Conroe added to downstream flooding. The goal: to find enough upstream detention capacity to help offset future releases. The San Jacinto River Basin Study will examine that possibility. It’s unlikely that one reservoir will provide enough capacity. However, multiple smaller reservoirs may.

The study partners will release their results in the second half of 2020. Land acquisition and construction could take several additional years.

Dredging

Dredging is another essential element of flood mitigation on the West Fork of the San Jacinto. Sand buildup near the mouth of the river has created a giant sediment dam. The Army Corps removed three feet in a dredging effort that ended on Labor Day. But much remains.

Luckily, State Representative Dan Huberty sponsored legislation that allocated another $30 million. The Harris County Flood Bond allocated $10 million. The City of Houston allocated $6 million. Plus two more grant requests are still pending that could increase the total even more. And a disposal site for the material has already been permitted.

*Mouth Bar of the West Fork. Photo taken 12/3/2019.*

Last week, Harris County commissioners voted to proceed with additional dredging. Project managers are studying the most cost effective ways to proceed. We should see more dredging soon.

This money could also be used on the growing mouth bar of the East Fork.

State Highway 99 Extension

The extension of the Grand Parkway (State Highway 99) east and south to I-10 will open up vast new expanses of forest and farmland to high density development. The biggest threat will be to the East Fork watershed as construction moves through southeast Montgomery County and the northeast tip of Harris County into Liberty County.

*Eastward clearing for SH99 has reached Caney Creek near Lake Houston Park.*

Those are my predictions for the biggest stories of 2020. There’s a lot of good news in the forecast and much to remain vigilant about. Life seems to be a constant struggle between those who would increase and decrease our margin of safety when it comes to flooding.

844 Days after Hurricane Harvey

The thoughts expressed in this post represent opinions on matters of public concern and safety. They are protected by the First Amendment of the US Constitution and the Anti-SLAPP Statute of the Great State of Texas.

The Biggest Stories of 2019

With 2019 almost behind us, we should look back to see what we accomplished on flood mitigation. Tomorrow, I’ll take a look at the stories that will likely define 2020.

Limited Dredging

In 2018, FEMA and the Army Corps announced that they would dredge 2.1 miles of the San Jacinto West Fork when they were given authority to dredge 8 miles. Questions immediately started to swirl about why they were not dredging all the way to Lake Houston. The answer was “part of the mouth bar was there before Harvey and we can only spend disaster relief funds on what Harvey deposited.”

*The mouth bar as it existed shortly after Hurricane Harvey. Photo taken 9/14/2017.*

After arguing for more than a year with the City about how much sediment FEMA deposited, the Corps finally decided to dredge 500,000 cubic yards from a 600 acre acre in front of the mouth bar. They finished on or about Labor Day. Then the dredging contractors waited several more weeks to see if there would be an additional assignment. There was not. They then departe d in October.

Regardless, they left the biggest blockage in the river. Imelda washed a tremendous amount of sediment downriver. In mid-October, RD Kissling sent me a photo from his kayak. He as standing in water less than knee deep 700 yards south of the mouth bar. It’s important to understand that sand bars are like ice bergs. You only see the tip above water. Most of the bar exists below water. And much of this mouth bar remains to be removed.

We need to cut a channel through this area to the lake to restore conveyance of the river. If Harvey couldn’t blow this dune out of there, nothing will.

To learn more about this controversy, search this site using the key words “mouth bar.”

Flood Mitigation Legislation: A Big Win

No one budgets for disasters, such as Hurricane Harvey. So after the disaster, cities and counties had to scramble for grant money to even qualify for matching funds from the Federal government. More than two and a half years after the event, money is finally starting to trickle down to the areas that need it to implement flood mitigation projects. That’s thanks in large part to Senator Brandon Creighton who authored Senate Bill 7.

SB7 creates dedicated Texas Infrastructure and Texas Infrastructure Resiliency Funds for flood control planning and the funding of flood planning, mitigation, and infrastructure projects. The Texas Water Development Board is finalizing rules for the distribution of those funds right now. SB500, a supplemental appropriations bill, includes funding for SB7 and an amendment that would dedicate $30 million for dredging at the confluence of the San Jacinto and Lake Houston. State Representative Dan Huberty authored the amendment to SB500 that provides the $30 million.

For more information about legislation affecting this area, see the Legislation page of this web site or search using the key words “SB7” or “SB500.”

Sand Mining Legislation: One Small Gain, Some Big Losses

Activists statewide pushed for legislation to reign in the excesses of an out-of-control aggregate industry. Here in the Houston area, State Representative Dan Huberty introduced HB 907. It passed and doubles the penalties for not registering a sand mining operation. It also increases the frequency of inspection from every three years to two years and established a registry of active sand mines.

Picture of the West Fork of the San Jacinto the day it turned white (11/4/2019). The TCEQ later issued a notice of enforcement to the Liberty Materials mine upstream for dumping 56 million gallons of white goopy pollution into the West Fork. *Water samples indicated 25 times the normal amount of suspended solids.*

That was the only bill that the high powered lobbyists of TACA (the Texas Aggregate and Concrete Association) would allow to pass. That’s mostly because their members are already registered.

However, other important bills died in committee due to the lobbying power of TACA.

HB 908 would have provided for penalties up to $50,000 for water code violations and every-other-year inspections.
HB 909 would have created best management practices for sand mines.
HB 1671 would have extended water quality protections to the West Fork of the San Jacinto currently enjoyed by the John Graves District on the Brazos and attached penalties for non-compliance with best practices defined under HB909.
HB 2871. Would require sand mines and other aggregate production operations to acquire a reclamation permit and to file a performance bond ensuring reclamation.

For more information about sand mining in the Lake Houston area, see the Sand Mining page of this web site. You can also search on the key words “sand mining, TACA, Triple PG, TCEQ, breach, Liberty, and white water.”

High Rises Near the Floodway of the West Fork

Early in the year, two investors from Mexico announced plans to build a series of high rises surrounded by more than 5000 condos in the floodplains and wetlands near River Grove Park. Their company, Romerica, proposed to build the high rises on land that was deed restricted to single family residential development. They even proposed underground parking!

*Artist’s conceptual drawing of a high-rise development called The Herons: Kingwood.*

The tallest buildings would have been 500 feet and located on the edge of the current floodway. That floodway will almost certainly expand in light of new Atlas-14 rainfall data. The developers also announced a marina that would have held 640 40-foot boats and 200 jet skis. There were no evacuation routes that would have remained above water in the event of a flood.

A massive public outcry arose. More than 700 people and organizations filed letters of protest with the Army Corps, TCEQ and the US Fish and Wildlife Service. In the end, regulators showed good judgment and common sense. The Corps withdrew Romerica’s permit application.

The developer’s web site now says the project is on hold, pending improvements to the West Fork and Lake Houston.

For more information on this development, see the High Rises page of this web site or search for the key words “Romerica, high rises, eagle, or The Herons.”

The $2.5 Billion Flood Bond Equity Flap

When the wording for Harris County’s historic $2.5 billion flood bond offering was worked out in early 2018, leaders from the Humble/Kingwood area in Precinct 4 argued to include the notion of an equitable distribution of funds. Why? Historically the Flood Control District had focused more on projects in other parts of the county, especially Precinct 1, that Precinct 4.

Humble/Kingwood voters turned out in record numbers to support the bond. It passed. But when it came time to implement the projects, Commissioner Rodney Ellis from Precinct 1 tried to redefine equity to mean reparations for historical discrimination, i.e., slavery.

In one meeting after another, Ellis’ ringers showed up in commissioners court to complain about discrimination in the distribution of funds for buyouts, construction spending, and more. Yet in every category, Ellis’ precinct already had the lion’s share of funding.

This is an on-going controversy that affects everyone in the Lake Houston area. Ellis is looting transportation dollars from Precinct 4. You have to hand it to Ellis. Even if he doesn’t know what equity means, he knows how to work the system.

For more information on this topic, search this site using the key words “equity or Ellis.”

Proposition A

In 2010, voters managed to get a referendum on the ballot that would create a dedicated fund for drainage improvements. It passed by a narrow margin. Almost immediately, city officials started using the money it raised for other purposes.

Meanwhile, the Supreme Court of Texas ruled that the language in the summary of the referendum on the ballot was misleading. It failed to disclose that the money would be raised through a new tax. So the Court ordered a revote.

In 2018, the Mayor “resold” the fee by saying, “If you want a lockbox around the money, vote FOR Proposition A. If you don’t want a lockbox around the money, vote AGAINST it.”

It was another artful dodge. There was nothing in the language of the bill to create a lockbox. The language in Prop A was almost identical to the original bill. But the funding formula was even looser!

Unaware voters once again approved the fee. And the Mayor continued to divert money from the fund. These diversions became a central element in the Mayoral campaign this year after thousands of people flooded in May and again during Imelda.

Nevertheless, the Mayor won re-election.

To learn more about this topic, search this site using the key word “Proposition A.”

10 New Gates for Lake Houston

The flood gates on Lake Conroe can release water 15 times faster than the gates on Lake Houston. During Harvey, that bottleneck contributed to the flooding of thousands of homes. A study showed that additional gates would have lowered the water level by almost two feet in the event of another Harvey. During smaller storms, the gates would also help pre-release water faster to create a buffer against possible flooding.

*Lake Houston can shed water at 10,000 cubic feet per second. Lake Conroe can shed it at 150,000 cubic feet per second.*

The City of Houston applied for a grant from FEMA and the Texas Division of Emergency Management to add ten new gates. FEMA approved the project. It’s happening in two phases. The first includes design and an environmental survey. The second includes construction. Each will take 18 months. We’re now six months into Phase One.

For more information on this topic, search this site using the key word “gates.”

Temporary Seasonal Lowering of Lake Conroe

After Harvey, people in the Lake Houston area started pleading for more upstream detention, dredging and gates. Dredging started immediately. The project to add more gates to the Lake Houston spillway has also started. Upstream detention is still years way. The San Jacinto Watershed Study is only now beginning to identify possible locations.

To help provide Lake Houston area residents with an additional buffer against flooding while officials worked on these mitigation measures, the SJRA Board voted to lower the level of Lake Conroe seasonally and temporarily. One foot during the rainiest months in Spring and two feet during the peak of hurricane season.

Many lakefront property owners on Lake Conroe, however, claim the lowering hurts their property values and damages their bulkheads. Buses full of protesters showed up at the December SJRA Board meeting wearing red shirts that say, “Stop the Drop.” So many came that two busloads full of people had to be turned away.

*Angry Lake Conroe residents showed up at the last SJRA board meeting in busloads.*

Net: the policy to lower Lake Conroe temporarily is under assault. The SJRA will likely vote on whether to continue the policy in February. The SJRA will hold two additional meetings at the Lonestar Convention and Conference Center in January and February to give everyone who wants to provide input a chance to do so.

For more information on this topic, search this site using the key words “lake lowering.”

Flooding from Upstream Development

By far, the biggest and saddest story of the year had to be the flooding of Elm Grove Village, North Kingwood Forest, and even many homes in Porter. Not once, but twice this year. In each instance, runoff from Perry Homes’ newly clearcut 268-acre Woodridge Village development spilled over into surrounding streets and homes. Perry Homes filled in natural streams and wetlands without an Army Corps permit. And they still have not even installed 25% of the detention capacity required for an area that large.

*The evacuation of Elm Grove* *after Perry Homes clearcut 268 adjoining acres.*

They haven’t even finished the detention ponds they started, in direct violation of a promise to the City of Houston. In fact, Perry Homes has shown no interest in resolving the problems it created. They have scarcely done any work on this site since August. Meanwhile hundreds of residents live under the heightened threat of flooding.

This is another issue that will carry over into 2020.

842 Days after Hurricane Harvey and 92 since Imelda

The thoughts expressed in this post represent opinions on matters of public concern and safety. They are protected by the First Amendment of the US Constitution and the Anti-SLAPP Statute of the Great State of Texas.

Plans For Next Phase of Dredging Announced

Behind-the-scenes work for the next phase of dredging has already started. The City, County and State are working together on a $30 million grant application for submission this month. The legislature earmarked the money for dredging at the confluence of the San Jacinto and Lake Houston. However, the money must go through the Texas Water Development Board (TWDB) to Harris County and then the Harris County Flood Control District.

Circuitous Route for Funding

The supplemental appropriations bill, SB500, that the legislature approved dictates the circuitous route for funding. See the exact text from SB500 below.

“Out of funds appropriated in Subsection (1), $30 million is dedicated to the Texas Water Development Board to provide a grant to Harris County for the purchase and operation of equipment to remove accumulated siltation and sediment deposits located at the confluence of the San Jacinto River and Lake Houston.”

DIY vs. Outsourcing

State Representative Dan Huberty, who authored the SB500 amendment, has worked closely with all parties involved to explore the most cost-effective and timely solutions. For instance, Flood Control explored how much it would cost to hire an outside company for dredging versus buying the equipment and doing it themselves. Said Huberty, “In my discussion with the TWDB last week, they have agreed we can buy equipment if we need to, which is the direction we are pushing for at this time.” However, that option would take longer to implement and the money must be spent within the current bi-annum – by law.

Long Term vs. Immediate Needs

Meanwhile, the East and West Forks of the San Jacinto have urgent, immediate dredging needs, too. So the partners could break the work up and pursue both DIY and outsourcing options.

Said Huberty, “I met with DRC (Disaster Recovery Corporation) a week ago. DRC has an ongoing contract with both the City and County for debris removal from Lake Houston and they are still removing debris from the lake. So they might be an option that would let us deploy faster.”

DRC is the parent company of Callan Marine, a subcontractor during the Army Corps’ Emergency West Fork Dredging project after Hurricane Harvey.

The dredges are gone but the pipe is not. The quarter-mile long sections of pipe used in the initial Emergency West Fork Dredging Project have been broken down into smaller sections for transport, but much of it remains on the West Fork. *Photo taken 12/3/2019*.

Additional Sources of Funding

Huberty also said that, “In addition to the $30 million, the Houston Mayor Sylvester Turner and Council Member Dave Martin committed last weekend to help us fund this in partnership with Harris County Flood Control.” The City committed approximately $6 million, according to Huberty.

*The growing mouth bar on the East Fork of the San Jacinto near the entrance to Luce Bayou and the Interbasin Transfer Project.*

The Inter-Basin Transfer canal empties into the lower reaches of Luce Bayou, which flows into the northeastern corner of Lake Houston, near the emerging mouth bar. The project costs $351 million and will provide water to the Northeast Purification Plant. Photo taken 12/3/2019.

“In addition,” says Huberty, “I spoke to the Governor’s staff this weekend. We still have money left over from Harvey debris removal. That’s approximately another $16 million. They told us we can spend the money on the river and lake, but not for other purposes. This will let us complete the mouth bar dredging and get mechanical dredging done in areas like Huffman and Atascocita. The scope of the project is expanding, which is very good news. We’ll be able to help more people.”

Smaller mouth bars have set up around the lake at the entrance to drainage ditches, like this one in Atascocita near Walden. Photo taken on 10/4/2019. Such blockages can force water up, out and over the banks into neighborhoods during large rains.

Next Step: Commissioners’ Court Needs to Approve Grant Request

The ball, at this moment, is in Flood Control’s court. Commissioners’ Court must approve all grant requests made by any part of the County. Says Huberty, “There will be an item on the December 17^th Commissioners Court agenda requesting permission from the Court to submit the grant application to TWDB. All parties involved have already had discussions with the TWDB staff and are working on the grant application paperwork.”

Early next week Huberty plans to meet with John Blount, the Harris County Engineer; Stephen Costello, the Mayor’s Flood Czar; and John Sullivan, President of DRC.

Constant Dredging for Foreseeable Future

“In my discussions with all interested parties,” said Huberty, “we should have the application submitted by year end. We have been pushing to get it awarded quickly. It is a formality. We need to spend this money quickly which works to our advantage. We can always go back to the legislature for more after that.”

“All of these initiatives will ensure we can have constant, permanent dredging on the Lake for the foreseeable future,” said Huberty. “I am very pleased with the result and look forward to getting this project started.”

KSA Parks Committee Votes to Dredge River Grove Park Boat Ramp and Boardwalk

At its November meeting, the Kingwood Service Association (KSA) Parks Committee voted to dredge the boardwalk and boat ramp areas of River Grove Park. The work, when done, will finally restore the park to full function.

Harvey Nearly Destroyed Park

Hurricane Harvey nearly destroyed River Grove Park. Thanks to KSA, the park has made a remarkable comeback. Harvey deposited sand five feet high in the parking lot. It left a wall of sand 12 feet high and a quarter mile long that blocked the drainage ditch that runs through the park and empties the western third of Kingwood. In the process, it also blocked the park’s boat ramp, only one on the West Fork. Finally, the storm deposited sand in the lagoon by the boardwalk and across the southern end of the soccer fields.

By the time the park is fully restored, repairs will have taken more than two and a half years.

Boat Ramp After Harvey

The Army Corps spent weeks opening up the drainage ditch that contains the boat ramp. Contractors dredged a 250-foot wide opening in the bar. Here’s how that area looked then and now from a satellite and helicopter.

*Google Earth image from October 2017 shows the massive sand bar blocking the boat ramp and drainage ditch that empties the western third of Kingwood.*

*How the sandbar looked from a helicopter two weeks after Harvey.*

Sand Bar After Dredging

*Boats can now get through the bar, but the area immediately in front of the boat ramp is still filled with sediment.* *Photo taken October 2, 2019.*

Even though boats can get by the sand bar now, they can’t get in and out of the water. Sediment remains around the ramp area and must be dredged. The Corps dredge was too big to maneuver in the tight space around the dock.

The Corps asked KSA not to open its boat docks in the name of safety while dredgers were still working the West Fork. Now, with dredging done and all the dredge pipe removed, KSA can work on reopening the dock.

Lagoon Also Filled with Sediment

The lagoon opposite the boardwalk filled with sediment during Harvey, too. Here’s what it looked like two weeks after Harvey.

*The lagoon next to the boardwalk totally filled in with sand deposited by Hurricane Harvey. Photo also taken two weeks after Harvey.*

Since then, vegetation has grown on the sand.

*River Grove boardwalk area two years later.*

Timetable for Dredging

KSA is now applying for a permit to remove the sediment from both the boat dock and boardwalk areas. KSA will use mechanical rather than hydraulic dredges.

The Association has already located a placement area for the spoils far from the river and any flood plain.

If permitted, removal of the sediment around the dock and boardwalk would begin in January.

Removal should take 6-8 weeks. Sediment will be placed on the parking lot to drain and dry. Then it will be trucked to the placement area in Humble.

The park could be fully functional again as early as March next year.

Public Soccer Fields Now Available

While working to prepare this project, KSA also restored the soccer fields which had been covered with sand several feet thick. All fields are now playable and KSA has designated two as public fields.

All in all, it’s been a remarkable comeback for a park that Harvey all but destroyed.

A Brief History of Lake Houston, the West Fork Mouth Bar and Attempts to Mobilize Dredging of It

Tim Garfield and RD Kissling, two of the world’s top geoscientists, happen to live in the Lake Houston Area. Both spent careers as highly placed executives for one of the world’s largest oil companies. Together, they have led the charge to raise awareness of the growing mouth bar on the West Fork of the San Jacinto where it meets Lake Houston. They have also lobbied long and hard with local leaders and the Army Corps to mobilize an effort to dredge the mouth bar.

On October 2, Garfield gave a presentation to the University of Houston Honors College. Debbie Z. Harwell, PhD, a history instructor at the college and editor of Houston History Magazine, organized the talk. Garfield summarized the history of Lake Houston, the West Fork Mouth Bar and attempts to mobilize a dredging program to remove the bar. The presentation is thoroughly researched and highly interesting. It focuses on the intersection of geologic and human history. Anyone interested in geology, flooding, history or politics should find it informative, fascinating and stimulating.

If you really want to learn what’s happening in the river and why, this is a must read.

You can download the entire 69-page presentation here. It’s titled “A Brief History of Lake Houston and the Hurricane Harvey Flood: The Combined Effects of Record Rain, Human Error and Predictable Geomorphic Processes.”

An Advancing Delta at Your Doorstep

The mouth bar is not just a giant sand bar at the mouth of the river. It’s part of an advancing delta system within the river and now the lake. Garfield and Kissling made careers out of studying deltas like this around the world. They point out that the delta’s growth is inevitable and the result of predictable geomorphic processes. All the more reason to take it seriously and plan for regular dredging to keep that channel open.

Yet attempts to remove the threat have largely been unsuccessful and largely for political reasons. The Corps did mount a nominal dredging program in July and August. But it was largely symbolic. They removed about 20-25% of what it would take to extend the upstream dredging channel through the mouth bar.

A post dredging survey shows that the Corps created an underwater box canyon that continues to slow down water and accelerate the deposition of sediment.

In fact, they left far more sediment behind than they dredged. Why? Was there some science to the decision to leave most of it in place? Have they made public a model for peer review that shows this was a good idea? In a word, NO!

Lack of Coherent Dredging Plan

Kissling and Garfield lament the lack of holistic understanding and a coherent dredging plan. I experienced this problem first hand. Before the Corps started dredging the mouth bar area, I requested their plans. The response I got shocked me. “Plans? What do you mean by plans?” That question came on the day of the deadline for processing my Freedom of Information Act request. I replied, “You know…plans…like the ones you shared for the first phase of dredging. Start points. Stop points. Channel widths. Depths. Objectives.” Twenty-three days later, they sent me a CD with 800 pages of uncatalogued information. Not one page dealt with plans. When I complained, they invited me to submit another FOIA request, saying that the first one had been closed out already. I declined their offer.

Clearly, they didn’t have a plan. Except to force the City to assume responsibility for dredging. The Corps and FEMA felt that if the City had done maintenance dredging years ago, the problem would not have become acute.

Since October of last year, the two sides (City and Corps/FEMA) have been playing a political ping pong match, each trying to get the other to dredge.

Post Script: Dredging Update

When contractors finished dredging 500,000 cubic yards from the mouth bar around Labor Day this year, they waited patiently for local authorities to come up with their own plan. Callan Marine got tired of waiting first. Their dredge was last seen weeks ago heading south on 59 in pieces on flatbed trucks.

Great Lakes Dredge and Dock had a dredge anchored at the mouth bar for six weeks. However, today, their dredge and booster pumps have been pulled back to the West Lake Houston Parkway Bridge.

A crane is dismantling the dredge enough to get it under the bridge and back to the command post. Great Lakes is demobilizing. That will leave no dredging equipment in the river.

As of Friday afternoon, according to Stephen Costello, the City filed another request with FEMA. The request was reportedly to allow the City to apply $9 million left over from its debris clean up budget from Harvey to additional debris removal. Unfortunately, going by past experience, remobilizing a dredging effort will cost far more than that.

Ironically, this latest development comes almost a year to the day after the so-called “Everybody-but-Trump” meeting in Austin. At that meeting, according to Houston City Council Member Dave Martin, both sides reached an agreement in principle to dredge the mouth bar.

Learn More at Town Hall Meeting This Thursday

It will be interesting to see what the City announces at its October Town Hall Meeting at the Kingwood Community Center this Thursday.

Be there. 6:30 PM. On the agenda:

Mayor Turner
Council Member Dave Martin
Stephen Costello, the City’s flood czar, to talk about dredging and dam improvements
SJRA’s Chuck Gilman to talk about status of the regional watershed study
Public Works and Coastal Water Authority to talk about dam repairs and lower lake levels for the next year
Houston Parks Board to talk about an extension of their Bayou Greenways Program south of Hamblen
And more

Army Corps Now 70% Complete with Its Portion of Mouth Bar Dredging

The Army Corps has released a new summary of its progress on dredging the mouth bar. The report indicates that Great Lakes, the contractor is now 70% complete. They have dredged 350,000 out of 500,000 cubic yards.

Great Lakes started dredging the mouth bar on June 25th, 2019, as part of a $17,085,861 extension of the original contract (FEMA mission assignment SWD-30).

Current area of operation is the blue area on the far right. Sediment removed from that area is being pumped 10 miles back upstream to Placement Area #2, a sand mine near Kingwood College, on the far left.

Between the start of mouth bar dredging and August 12, Great Lakes dredged an average of 6,363 cubic yards per day. If they can keep that pace up, they should be done by approximately Labor Day – three months ahead of schedule. That’s HALF the predicted time.

Remainder of Project Still Not Decided

What comes next? That still has not been finalized. City, County and State officials have been meeting in the background to determine that. The Army Corps still has not accepted or rejected Berry Madden’s property as a third placement area. And the $30 million appropriated by the State for mouth bar dredging won’t even become available until September 1st.

Meanwhile, Callan Marine, the subcontractor from the original West Fork Emergency Dredging job has pulled its equipment back to the dock opposite Forest Cove. However, Callan has not yet started disassembling its equipment and removing it from the river. According to Houston City Councilman Dave Martin, Callan has agreed to stay temporarily while officials attempt to work out details for the next phase of dredging.

RD Kissling and Tim Garfield, two local geologists who first brought the mouth bar issue to the public’s attention, estimate that 500,000 cubic yards is about one-fourth of the total sediment that must be removed to fully restore conveyance of the West Fork.

How Shallow is It?

The Corps has not yet released (or even developed) plans for mouth bar dredging. We do know the volume they intend to remove, and the general area they intend to remove it from. However, they have refused to divulge how much of a dent their efforts will make in solving the problem.

*This photo of a Kings River resident wading across the river shows how shallow it is near the orange channel marker.* *This resident says boats “beach” behind his property almost every day.* *Note: Deeper pockets may exist, especially near dredging equipment. The risk of drowning is real. Do not let children attempt this.* *Photo taken Sunday, August 10, 2019.*

*The resident made it almost to the channel marker without getting his shorts wet.* *Shot taken with 6X telephoto lens.*

*The lake/river within this area averages two to three feet deep. 500,000 cubic yards would lower the average level by another three feet as this calculation shows.*

Problem With Stopping after 500,000 CY

The problem with stopping after the Corps finishes its 500,000 cubic yards is that the river behind this area is much deeper. Where the Corps stopped dredging just past Kings Harbor, the river is now 25-30 feet deep. And places are even deeper according to fishermen. That means water coming downriver will be forced to flow uphill in this area. That will force it to slow down and more sediment will rapidly drop out of suspension. Some experts have suggested dredging a deep channel through this area to help restore full conveyance of the river. However, the Army Corps intends to stop after 500,000 cubic yards.

How Army Corps Sees its Role

The Army Corps has prepared a series of FAQs that represent its position on the remainder of mouth bar dredging. Among them:

“Q: What is USACE Galveston District’s plan for the rest of the mouth bar?“

“A. There is no additional work planned for the mouth bar. The current plan for the modification addressing material near the mouth bar can be found on the placemat. USACE Galveston District has no authority to conduct any additional work in the West Fork of the San Jacinto River or Lake Houston. The San Jacinto River is not an authorized federal waterway, the Corps of Engineers dredging operations are currently limited to dredging Harvey-related material. The ongoing work under the contract modification will remove the remainder of material attributable directly to Hurricane Harvey. The sedimentation from recurring annual flows are not within USACE Galveston District’s mission assignment from FEMA. Water flows on the West Fork of San Jacinto River were restored to pre-Harvey levels in December 2018.”

“Q: Who can the public contact for additional concerns with the maintenance of the San Jacinto River?“

“A. For concerns with the maintenance of the San Jacinto River, please contact Harris County Flood Control District, the San Jacinto River Authority and the City of Houston.”

Punt!

Meanwhile the City is still arguing with the Corps about how they arrived at 500,000 cubic yards. More on that later. I have obtained the Corps’ estimate through a FOIA request to the City of Houston. It raises many questions that I am still trying to sort through. More on that later.

Government Gone Wild: Army Corp Refuses to Release Dredging Documents that Explain Decisions, Delays

The Army Corps has refused to release documents that explain key decisions, delays and plans related to West Fork mouth bar dredging, and a potential placement area for the spoils. At issue are the Corps’ decisions to dredge only 500,000 cubic yards from the area of the mouth bar and to delay approval of the City’s proposed placement area for long-term dredging.

As a result of a Freedom of Information Act (FOIA) request related to these decisions, I also learned that the Corps:

Is dredging near the mouth bar without a plan
Is almost done with the mouth bar project and hopes to have a plan before it finishes
Has repeatedly delayed a decision on a new placement area that could have saved millions of tax dollars.

Meanwhile, the Corps continues sending sediment to a mine that leaks it back into the river. That mine – in the floodway – has a dubious environmental record at best. This seems to be a case of Government Gone Wild.

Dueling Studies Offer Different Opinions of Harvey-related Mouth Bar Volume

The City of Houston and Army Corps have reportedly argued for a year or more about how much sediment Harvey deposited in the mouth bar. Late last year, FEMA required the City to perform a core-sample study using something called the Stockton Protocol. The City hired Tetra Tech to do it. And Tetra Tech concluded Harvey deposited 1.4 million cubic yards. Here is their study.

The Corps, however, evidently did not buy the results. The Corps conducted another study for FEMA using a different protocol. It concluded Harvey deposited 500,000 cubic yards.

The Corps, however, refused to release the results of that study for public review.

FEMA and the Corps went ahead and hired Great Lakes to dredge that volume from the mouth bar. That job is now more than half complete.

As part of their refusal to release their study, they cited the need to keep “pre-decision” information confidential so that inter- and intra-agency personnel could debate the merits of proposals freely. I get that. What I don’t get is how they justify this as “pre-decision.” The job is almost complete!

Dredging Without a Plan

While inventorying the documents that the Corps DID send me, I also discovered that they are now dredging the mouth bar area – without a plan. I know this because I requested the plan and they did not supply it. A Corps representative then explained that they are still working on the plan. They hope to have it done before they complete the $17 million job.

Wasteful Spending?

The Corps could be saving much of that money by using Berry Madden’s property near Kings Lake Estates as a disposal site. That’s because they need more than 5,000 gallons of diesel per day and two extra boosters (plus their crews) to pump sediment 10 miles upriver to an old West Fork sand mine in the floodway.

At the current price of diesel (about $3/gallon), that’s about $15,000 per day for fuel alone. More than $100,000 per week. And more than $400,000 per month. Waaaaay more than the limit on my gas cards. So what does the Corps get for all that?

Dike Breaches of Placement Area in Floodway

Minor floods last December breached the dike of that sand mine at least three times. Sediment continues to sweep out of the mine.

*Placement Area #2 near Kingwood College on West Fork. This image is from February, but it is the same mine, whose dikes were breached in December.*

It has caused additional shoaling (see below) that will need to be removed some day near the I-69 bridge. It even buried Great Lakes pipes, causing cost overruns for Phase 1.

*Shoaling has become so bad through this reach of the river that it buried Great Lakes pipeline, resulting in cost overruns.*

A year ago, this same mine was caught on camera deliberately sending its process water straight into the West Fork.

Video provided to ReduceFlooding.Com. Source wishes to remain anonymous.

Yet, while approving this site, the Corps reportedly has environmental concerns over a much closer disposal site that would require less fuel and fewer boosters. It’s also on higher ground and out of the floodway. It’s Berry Madden’s property in Humble immediately west of Kings Lake Estates between the West Fork and 1960.

*Five different proposed placement areas on Madden property avoid wetlands (the cross-hatched areas).*

The Corps may or may not have good reasons for disliking the property, but they won’t reveal them whatever they are.

After more than a year of environmental and archeological studies costing Madden more than $100,000, the Corps still has not approved or rejected his property. Nor have they explained delays in approving or rejecting it. The documents that the Corps DID supply show that they are throwing one obstacle after another in Madden’s path. Despite the fact that he’s on higher ground and farther from the river than the current placement area.

Meanwhile, the Corps subsidizes the sub-optimal sand mine/placement area above. Go figure!

Potential Setback for Future Dredging

One of the consequences of NOT having an approved site to store additional spoils is that it could delay future phases of dredging. Those potentially include:

Additional mouth bar dredging
59 to River Grove Park
Maintenance dredging
Mouths of ditches such as Ben’s Branch

FOIA Scorecard

I filed my Freedom of Information Act (FOIA) request with the Army Corps 50 days ago. I requested:

Their plans for mouth-bar dredging
Conference reports of meetings where the mouth bar was discussed
Documents relating to the approval of Berry Madden’s property in Humble as a potential storage site.

About a month ago, they requested a clarification. “What do you mean by ‘plans’?” Seriously! The U.S. Army Corps of Engineers needed to have the concept of plans explained????!!!

After more delays and excuses, five days ago, I received a compact disk in the mail with approximately 800 total pages of material. The Corps:

OMITTED any mouth-bar plans.
OMITTED the Corps study that contradicted the Tetra Tech study.
WITHHELD 118 pages of material that could have explained their decision.
REDACTED key correspondence relating to Madden’s property.
SUBSTITUTED dredging status reports from contractor meetings for conference reports of meetings among City, State and Federal officials where decisions about the mouth bar were considered.

Government Gone Wild

After several phone calls in which I tried to cajole them into supplying the Corps’ study, I received another email from the Corps. It said that they considered my original FOIA request closed. They then asked me to submit another one for the same material that I requested in June. They seem to be treating this as a national-security issue, not a public-safety issue. Why?

Here’s the explanation from the Corps. The letter claims that they need to keep pre-decision information secret in order to foster free discussion between its employees and other government agencies and to avoid confusing the public.

Unfortunately, that does not allow informed discussion among the public, whose safety is at stake. Nor does it recognize the fact that they have already made a decision, i.e, to dredge 500,000 cubic yards and have half-completed the project. So how does this qualify as “pre-decisional”?

You’ll have to ask the man who signed this letter.

He has the title “Initial Denial Authority.” How many levels are there?

In my opinion, this is clearly a government agency out of control. The Corps has made a decision to dredge only 500,000 cubic yards – despite scientific evidence supporting a higher volume of 1.4 million cubic yards. And that scientific evidence was acquired using a protocol that the CORPS AND FEMA DEMANDED.

Who Will Pick Up the Pieces?

That leaves the State, County, City and the public in the lurch. Maybe a Congressional investigation could sort this out. That’s what it will take.

At this point, it’s not clear how, when or if the mouth-bar job will be finished. Five hundred thousand cubic yards is a small fraction of what needs to be removed to restore conveyance to the river.

It’s also not clear how many more hurdles the Corps will put in the way of a placement area farther from the river on higher ground. Or why.

A curtain of secrecy has descended upon this job. I will continue to follow the story. The public has a right to know.

Open Offer to Corps to Rebut Criticisms

If the Corps feels I have criticized it unjustly, I invite a spokesperson to explain the Corps point of view. I promise to reprint the rebuttal verbatim.

Weekly Mouth Bar Dredging Update with Images from Carolyn Daniel, Kendall Taft, Franz Willette of BCAeronautics, and the Army Corps

We learned a little bit more this week about the next phase of dredging. Several graphics (below) released by the Corps summarize modifications to the Emergency West Fork Debris Removal Project.

What We Confirmed and Learned

We confirmed that:

Great Lakes, the prime contractor on the original job, will be the only contractor on the Corps portion of the contract extension
Great Lakes will pump sediment all the way upstream to Placement Area 2
The Corps intends to dredge 500,000 cubic yards in the area of the mouth bar.

We learned that:

The original contract contingency allotment of approximately $3.5 million was used up, most likely by additional sediment washed downstream during floods in December, January, February, May and June.
Callan, the subcontractor for phase one, has approximately 83,000 cubic yards to dredge due to modification of the original contract.
Dredging an additional 500,000 cubic yards will cost another $17,085,861
The FEMA/Corps portion of the dredging should finish by December 6, 2019
Demobilization and cleanup will take until Jan. 22, 2020
This is FEMA mission assignment SWD-30
Great Lakes started dredging the mouth bar on June 25th
Great Lakes will dredge a wide area but not go all the way to the FM1960 bridge.

Corps Releases Summary of Project and Extension(s)

I compiled the information above from a PDF developed by The Army Corps. They released it on July 9.

*First page of a 2-page PDF released by the Corps on July 9.*

*Second page of a 2-page PDF. Army Corps summary of Emergency West Fork Dredging project. For a high-resolution PDF, click here.*

To calculate the depth of dredging in that blue area to the right, I simulated the outline in Google Earth and found that it roughly equals 500,000 square yards. That means if they dredge this whole area, they will reduce the river bed by approximately 3 feet. The area already averages 2-3 feet deep. That means the river will be roughly 6 feet deep through this reach when the Corps finishes its portion of the job.

*The area outlined by Corps is approximately 500,000 square yards.*

Where Callan will finish dredging near Kings Harbor, the depth will be approximately 22.5 feet.

However, upstream, Callan is dredging to a depth of 22.5 feet. Thus, creating a continuous gradient along the river bottom would require dredging approximately another 16 feet deeper in the same area…and that wouldn’t even get you to the FM1960 bridge. Also, note the gap in the graphic between where Callan will finish its portion of Phase One and Great Lakes will start mouth bar dredging.

Unknowns

It is unclear at this point who will dredge the rest of the material that needs to be removed to restore conveyance of the West Fork. Neither the City, County, nor State have yet announced their plans. We don’t know:

Where they will dredge
How deep they will go
Where they will place the material
How much it will all cost, or
When they plan to do it.

In the meantime, here are two dramatic sequences of photos plus a video submitted by readers this week. They show what the start of mouth bar dredging looked like from the air and water.

Army Corps Moving Forward with Partial Mouth Bar Dredging to Reduce Flood Risk

The Army Corps announced Monday that it will begin dredging approximately 500,000 cubic yards of the giant sand bar at the mouth of the San Jacinto West Fork. It has been linked to flooding in the Humble-Kingwood-Atascocita area. However, previous estimates put the total volume at close to 2 million cubic yards, with the volume due to Harvey at 1.4 million cubic yards.

Text of Press Release

GALVESTON, Texas (June 10, 2019) – The U.S. Army Corps of Engineers Galveston District staff executed a modification to the West Fork San Jacinto River Emergency Debris Removal contract June 7, 2019, to dredge an additional 497,400 cubic yards of material that was deposited in the mouth of the San Jacinto River from Hurricane Harvey.

“This contract modification will ensure a decrease in threats to critical infrastructure and lower the risk to potential loss of life,” said Charles Wheeler, USACE Galveston District project manager. “This is an ongoing contract that is part of a Federal Emergency Management Agency mission assignment.”

According to USACE Galveston District officials, the dredged material will be placed at the existing location referred to as Placement Area 2, which is located approximately 10 miles upriver. The additional dredging is scheduled to be completed by the end of 2019, with the demobilization of the equipment completed by early 2020.

No Mention of Other Partners

The press release does not mention the City of Houston, Harris County, the State of Texas, or Congressman Dan Crenshaw’s office. Most had been negotiating with FEMA and the Corps as late as last Friday.

On two previous occasions, the City announced agreements in principle with FEMA and the Corps. However, the two sides still had many details to work out relating to volume, storage, permitting and cost. The City and FEMA have tried to reach agreement on the volume of sediment deposited by Harvey since last October – eight months.

In February, the City, hired Tetra Tech to collect and analyze core samples from the mouth bar. In late April, Tetra Tech estimated, through a protocol recommended by FEMA, that Harvey deposited 1.4 million cubic yards of sediment at the mouth of the river.

Two Sides Far Apart in Negotiating Volume

The Corps’ announcement reveals just how far apart the two sides were in their volume estimates – about 900,000 cubic yards. That difference means much of the mouth bar area will remain undredged – at least for now.

With approval to remove only about 500,000 cubic yards, the dredgers will have to cut a channel around the mouth bar, most likely on the deeper Atascocita side. Ironically, that would mean leaving behind sand deposited above water by Harvey – a decision that could confuse the public.

Great Lakes Dredge Moving into Position

Great Lakes finished dredging its half of Phase One on April 12, exactly two months ago. The company has waited patiently ever since for the decision that finally came last Friday.

Today, the Great Lakes dredge has anchored near Kings Harbor. Judging by the weeds and logs in the pictures below, it appears that they will have to dredge their way TO the mouth bar. That could use up some of the precious approved volume. It could also take several weeks to position and calibrate all the equipment necessary to pump sediment 10 miles upriver.

*Great Lakes Dredge has moved downriver east of West Lake Houston Parkway. It is anchored in front of Raffa’s in Kings Harbor.*

*Wider shot taken from the pier in Kings Harbor facing west toward the Great Lakes Dredge and the West Lake Houston Parkway bridge.*

*Callan dredge operating on the other side of the pier*. Dredgers are responsible only for work in the channel, not tidying up the shoreline. *While taking this shot this morning, I noticed that workers were finally starting to renovate Sharkey’s, one of the most popular restaurants in Kings Harbor before Harvey.*

What Comes Next?

Pumping sediment from the mouth bar to PA-2 will require the horsepower of the larger Great Lakes dredge. It will also require several extra booster pumps and miles of additional 24 inch pipeline. The Great Lakes dredge has now moved downstream and is anchored east of the West Lake Houston Parkway bridge near Kings Harbor.

Last week, dredge pipe re-appeared under the 59 bridge after being gone for two months. That fueled rumors that the two sides had finally worked out some kind of deal. At this hour, the mystery is where does the Corps’ decision leave all the other parties in this process? More important, where does it leave the remainder of the mouth bar?

Other Money Available

The state approved an additional $30 million for dredging the mouth bar last week. The county also allocated $10 million in the flood bond approved by voters last year (see item CI-61). That $40 million along with another $18 million committed by the City of Houston would add up to $58 million. In addition to the unspecified sum FEMA is fronting now, that might be enough to remove the entire mouth bar. That could happen one of two ways:

The City, Corps, FEMA and TDEM would have to increase the approved volume after the next phase starts or…
The City, County and TDEM would have to remove the rest without FEMA and the Corps.

However, money is just part of the problem. The second option might require permitting another placement area. Permitting could delay the project. But permitting a closer placement area might also save money. It gets complicated.

PA 1 is filling up rapidly as the pictures below show. And PA-2 is so far upriver from the mouth bar that would cost extra millions of dollars to use.

*Tail end of the Callan dredge pipe empties sediment into an old sand pit off Townsend in Humble.*

*Several months ago, this was all water. The owner of the pit is now selling sand to an asphalt company* *and the pit is still filling rapidly.*

Easy Way to Save Money

Shortening the distance between the mouth bar and the placement area could reduce the amount of diesel and manpower needed to run the booster bumps. Each booster uses more than one thousand gallons of diesel per day. So costs add up rapidly. That’s why the Corps is still considering other placement areas.

Berry Madden owns several thousand acres south of River Grove Park between the river and FM1960. According to Madden, using his property could save the government $5.5 million in pumping costs. And that’s just on the first 500,000 cubic yards. If 2 million cubic yards is an accurate estimate for the total mouth bar, using Madden’s property could save $22 million. That’s even more than the remobilization costs we were trying to save.

I hope we don’t stretch this out too much longer or make it any more difficult. My truck needs some repairs and I’m afraid, as a taxpayer, that I may not be able to afford them!

652 Days after Hurricane Harvey

Passage of SB 7 and SB 500 Should Speed Up Flood Mitigation Projects

Six hundred and thirty-seven days after Hurricane Harvey, the Texas Legislature finally passed and funded a massive flood-relief bill, Senate Bill #7 (SB 7), sponsored by State Senator Brandon Creighton. The lengthy delay between Harvey and the bill’s passage underscores the need for Creighton’s bill.

Need for Faster Mitigation

Few government entities, it seems, budget for emergencies. So when a tragedy like Harvey happens, cities and counties scurry around looking for small grants. They use those to hire consultants to apply for other small grants that provide matching funds for even bigger grants from FEMA.

There’s even a two-step process to get on the list for grant consideration at the Federal level. You don’t just apply to FEMA or HUD. First, you have to file an application with the TDEM (Texas Division of Emergency Management, a part of DPS) before you can file an application with FEMA.

Most of the begging goes on behind the scenes, out of sight to the average citizen. The fact that the City or County has applied for a grant falls below the threshold of newsworthiness in most cases and so remains invisible to all but insiders. Once someone approves the grants, lengthy permitting processes further delay construction. It take years for a mitigation project to get to the construction phase. That’s when a project becomes newsworthy again.

Changing a Frustrating Process

This is why, to the average citizen, the pace of flood mitigation appears maddeningly and frighteningly slow. Important projects, such as additional dredging, gates for Lake Houston, and upstream detention, seem perpetually mired in government red tape.

The passage of Senate Bill (SB) 7 and SB 500 could help change that. The Senate and House have passed both bills, which are on their way to Governor Abbott’s desk. State Representative Dan Huberty says the governor supports both bills and that his signature is certain.

Here’s what they do:

SB 7 sets up several different funds that will make it easier to launch flood mitigation projects.
SB 500 appropriates the money for the funds in SB 7.

Provisions in SB 7

SB 7 relates to flood planning, mitigation and infrastructure projects.

Article 1 in SB 7 provides money for: flood control planning; preparation of applications for regulatory approvals; and development of engineering plans/specifications for flood mitigation and drainage projects.

Article 2 establishes a special flood infrastructure fund to make loans (at or below market interest rates) for flood projects. It can also provide grants that provide matching funds to poorer political subdivisions that make them eligible to participate in federal programs.

Article 3 amends the state Water Code relating to the Texas Infrastructure Resiliency Fund by establishing special accounts for Floodplain Management, Hurricane Harvey, Federal Matching projects, and Flood Plan Implementation.

Provisions in SB 7 encourage cooperative planning and financing of projects across political boundaries. Those provisions support regional flood mitigation projects through the Flood Infrastructure Fund. That should be especially helpful in the Lake Houston area where mitigation projects affect multiple counties and cities.

SB 500 Provides the Funding

SB 500 is an appropriations bill. It provides funding SB 7 and other items. It appropriates out of the state’s economic stabilization (rainy day) fund:

$273 million to provide matching funds for Hazard Mitigations Grants administered by FEMA.
$365 million to provide matching funds for Public Assistance Grants administered by FEMA.

Out of those two sums, it also appropriates $30 million that may only be used to provide a grant to Harris County to remove accumulated silt and sediment at the confluence of the San Jacinto River and Lake Houston, i.e., The Mouth Bar! That came from an amendment to SB 7 proposed by State Representative Dan Huberty when the House considered the Senate Bill.

It also provides, among many other things:

$47 million for community assistance
$793 million for flood infrastructure projects (drainage, flood mitigation and flood control projects)
$857 million for the Texas infrastructure resiliency fund
$13 million to the Lone Star College system for expenses related to Hurricane Harvey.

Rep. Dan Huberty says that since SB 500 is a supplemental appropriations bill, money from it should be available immediately, as soon as the Governor signs it.

A Big Thank You to Creighton and Huberty

The 85th legislature adjourned less than three months before Harvey inundated South Texas. That delayed legislative action two years. As a result, ever since Harvey, local officials have scrambled to organize and fund flood mitigation projects. The passage of these two bills should speed that process up by providing seed money for planning, grant writing, and matching funds. Thanks go to Senator Brandon Creighton and his staff for responding to the need and pushing these bills through the legislature. Thanks also go to Representative Dan Huberty for earmarking money for mouth bar dredging.

*SB 500, a supplemental appropriations bill approved last weekend contains $30 million to help dredge the mouth bar on the West Fork of the San Jacinto.*

With West Fork Phase One dredging rapidly winding down, hopefully the addition of $30 million to any money contributed by the City and FEMA will enable dredgers to restore conveyance of the West Fork.

Finally, we should give a big thank you to all of you who wrote letters in support of these two important pieces of legislation.
