As of 10PM, travel conditions are becoming increasingly more difficult with the winter storm.
The freezing line has progressed to near the coast with upper 10’s spreading into the northern areas and mid 20’s into NW Harris County. Widespread freezing rain and sleet continues with accumulations in progress.
Roads have become extremely dangerous north of I-10 and most freeways have ice.
Freezing and frozen precipitation will continue for the next 8-12 hours. Gradually, the freezing rain will transition to more sleet and snow from NW to SE early Monday. Temperatures will fall into the mid-teens over much of the region overnight. Wind chills will dip into the single digits and below zero by morning.
Travel conditions will become nearly impossible overnight. Everyone should remain at their current location

A dangerous winter storm will move into the region starting late this afternoon lasting into Monday with crippling travel impacts.
Extraordinary cold for Monday and Tuesday
Second winter storm possible over portions of the area Tuesday night-Thursday morning
Discussion
Freezing line has progressed southeast overnight and extends from near Conroe to Cypress to Katy to Victoria. Light freezing rain and freezing drizzle has developed over parts of the area NW of the freezing line this morning and this is resulting in patchy ice forming on some bridges and overpasses across northwest Harris County and more widespread issues to the north and west. Travel to the north and west of Harris County is becoming dangerous and is ill advised.
Periods of light precipitation will be possible today with temperatures rising remaining below freezing generally NW of a Huntsville to Conroe to Hempstead to Wharton line and mid to upper 30’s south of that line.
A powerful upper level storm system will move across Texas tonight into Monday resulting in a significant and high impact winter storm. Strong arctic front will arrive this evening resulting in quickly falling temperatures along the development of widespread precipitation. Expect freezing rain to develop by late afternoon and early evening across much of the area and then transition to sleet and snow across much of the area late tonight into Monday. High resolution models continue to come in with a bit more snow over the area.
Accumulations:
Precipitation will onset late this afternoon and early this evening for most areas
Ice:
1/10 to 1/4 of an inch across most areas, especially the US 59 corridor
Snow:
Most of Houston will see 1-2 inches of snow, but areas to the north could see up to 6 inches according to the NWS.
4-6 inches: Houston and Trinity Counties
3-4 inches: College Station to Huntsville
2-3 inches: north of a line from Cleveland to Conroe to Hempstead to Columbus
1-2 inches: north of a line from Liberty to Houston to Sugar Land to Wharton
Less than an inch: south of a line from Winnie to League City to Bay City
Impacts
Travel:
Ice and snow falling with temperatures falling into the low 20’s and upper 10’s Monday morning will result in near impossible travel on all surfaces…this includes surface streets, sidewalks, and parking lots. Anyone attempting to travel has a high potential of becoming stranded…and the simple message is where you area Sunday evening is where you are going to be Tuesday.
Power:
Ice accumulations are right on the border between isolated and sporadic power outages and more significant widespread outages. Even with the marginal ice accumulations for widespread power disruption, winds of 15-25mph may be the key factor that pushes tree limbs and power lines past their breaking point. Residents should be prepared for power outages.
Historic Cold:
A most memorable cold air outbreak will accompany the winter precipitation. Temperatures will fall below freezing Sunday evening for many areas and remain below freezing into Tuesday and Wednesday…it is possible that areas from College Station to Huntsville do not get above freezing until Friday. The long duration of the sub-freezing temperatures along with the brutal intensity of the cold air mass is going to create extensive damage across the region to vegetation and infrastructure.
Expect most areas to fall into the 10’s and low 20’s on Monday (coast in the upper 20’s) and then continue to fall Monday night and bottom out with lows in the upper 1’s and low 10’s north of I-10 and upper 10’s and low 20’s near the beaches. College Station to Huntsville looking like lower to middle 1’s. Wind chills Monday night will fall into the -10’s and -1’s across much of the area.
This is life threatening cold and persons should limit outside exposure to short periods of time to avoid frostbite and hypothermia.
Lastly, given the intensity and duration of the cold, portions of lakes and ponds, stock ponds, and other small water bodies, etc. may freeze over with a layer of ice…DO NOT attempt to walk on any frozen water body as the ice will not be thick enough to support a person.
Time is running out to prepare for the extreme cold…have all preparations completed by this afternoon.
Jeff Lindner, Harris County Meteorologist
Preparations
Protect all and any exposed pipes, shut off and drain sprinkler systems. Open cabinet doors and closet doors to get as much heat against outside facing wall pipes as possible starting Sunday night. In some cases the best course of action may be to shut off water to a structure and drain pipes overnight when water usage is low to avoid pipes freezing and bursting.
Heavily cover and protect any tropical vegetation, citrus, or vulnerable plants. Given the intensity and depth of the freezing conditions this will likely be a killing freeze for much of the tropical landscape of this region.
Pets and livestock should have proper shelter, feed, and water. Normal water supplies will likely freeze over including stock ponds and lakes.
Persons should plan to limit outdoor exposure Monday and Tuesday as wind chills will be dangerously cold for our region. Prolonged exposure could result in frostbite and hypothermia.

1265 Days since Hurricane Harvey
https://i0.wp.com/reduceflooding.com/wp-content/uploads/2021/02/winter-storm-2.14.jpg?fit=989%2C555&ssl=1555989adminadmin2021-02-14 13:25:332021-02-14 13:25:36Dangerous Storm Bringing Quarter Inch of Ice, Two Inches of Snow, Single-Digit Temps To Houston
Jeff Lindner, Harris County Meteorologist reports that the winter-storm watch has now been upgraded to a winter-storm warning and that it will start at 9PM tonight. The winter storm will create severe travel hazards Sunday and Monday. He also warns that extreme cold on Monday and Tuesday will create widespread challenges.
A disturbance this evening and overnight will shift the freezing line southward. Precipitation will likely develop late this afternoon and evening over the area and linger into Sunday morning. Areas northwest of the freezing line will likely see accumulations of ice on bridges and overpasses and all elevated surfaces. Hence the Winter storm warning start time has moved up to 9 PM this evening. Travel conditions will likely become hazardous overnight. All precautions for the upcoming extreme cold should be completed today.
Sunday afternoon-Monday midday:
A much stronger upper-level storm system will move across Texas during this time. It will result in widespread freezing and frozen precipitation. Beginning late Sunday afternoon, the second wave will overspread the entire area by Sunday evening. Expect a mixture of freezing rain, sleet and snow across much of the entire area with more freezing rain along and south of I-10 and more sleet and snow north of I-10.
The latest models indicate more snow and sleet than previously expected. North winds of 15-25mph Sunday into Monday will add extra stress against ice coated trees and power lines. It could result in power outages.
Accumulations
Freezing rain: 1/10th to 1/4th an inch over much of the area, especially the US 59 corridor
Sleet: ½ to 1 inch mainly north of I-10
Snow: 1-2 inches north of I-10, 2-4 inches north of HWY 105
Much of the area will see a period of freezing rain with temperatures in the mid 20’s so a layer of ice will be formed below any sleet or snow.
Travel starting Sunday evening will become nearly impossible, says Lindner. Anyone attempting to travel should be prepared to become stranded on roadways.
Record-Breaking Cold Monday-Tuesday
Record breaking cold is likely. Temperatures will fall below freezing Sunday afternoon and likely remain below freezing into Wednesday. Models now indicate 8/9 instead of 11/13 for all areas north of I-10. Waller and Montgomery counties northward could see temperatures near 1 degree.
The cold will result in devastating impacts to infrastructure and vegetation.
Harris County Meteorologist Jeff Lindner
Wind chills Monday afternoon into Tuesday will fall near zero over the entire area. Limit time outdoors and make sure you cover exposed skin.
Preparations to Mitigate Against Property Damage
Protect exposed pipes
Shut off and drain sprinkler systems.
Open cabinet doors and closet doors to get as much heat against outside facing wall pipes as possible starting Sunday night.
In some cases the best course of action may be to shut off water to a structure and drain pipes overnight when water usage is low to avoid pipes freezing and bursting.
Heavily cover and protect any tropical vegetation, citrus, or vulnerable plants. Given the intensity and depth of the freezing conditions this will likely be a killing freeze for much of the tropical landscape of this region.
Pets and livestock should have proper shelter, feed, and water. Normal water supplies will likely freeze over including stock ponds and lakes.
Limit outdoor exposure Monday and Tuesday as wind chills will be dangerously cold for our region. Prolonged exposure could result in frostbite and hypothermia.
Keep a blanket in your car and make sure you have an ice scraper for your windows.
Detailed Forecast for Harris County
The winter storm warning will span several days.
Today: Cloudy with a 30% chance of afternoon and evening light rain and drizzle. High in the upper 30’s. N wind 10-15mph
Sunday: Cloudy with a 40% chance of light rain or drizzle early then a chance of freezing rain and sleet by evening. Temperatures steady in the mid 30’s. N wind 15-20mph. Wind chills in the 10’s and 20’s.
Monday: Cloudy with a 100% chance of freezing rain, sleet, and snow. Ice accumulation of up to 1/4th an inch and snow accumulation of 1-2 inches. Temperatures steady in the mid 20’s. N wind 15-25mph. Wind chills in the 10’s.
Tuesday: Partly cloudy with a low in the low to mid 10’s and high near 30. N wind 5-10mph. Wind chills 1’s.
Wednesday: Cloudy with a 60% chance of precipitation. Low in the mid 20’s and high in the mid 30’s. NE wind 10-15mph.

The preliminary engineering phase of the project to add more gates to Lake Houston is rapidly drawing to a close. Engineers should complete their final (preliminary) report on the Spillway Improvement project next month.
At the Coastal Water Authority board meeting on 2/10/21, Chris Mueller, PhD, PE, gave an update on the preliminary engineering report being prepared by Black & Veatch (BV) on the Lake Houston Spillway Improvement Project. Because the report is still in draft form, I won’t reproduce every slide here. Nor will I list exact flood-reduction benefits, which are still being refined. I will simply summarize some of the key points which seem unlikely to change at this point.
The final preliminary engineering report should be released next month. Before then, BV and subcontractors need to finish environmental surveys and their drainage analysis. They also need to put a sharper pencil to the Benefit/Cost Analysis, and prepare scope, schedule, and budget proposals for detailed engineering. The board will consider authorizing the next steps in its March 10 meeting.
Lake Houston Spillway photographed 1/1/2021.
Top-Ranked Alternatives to Date
BV’s top ranked alternatives to date include adding (in order of preference):
1000 feet of crest gates on the Spillway (see foreground in picture above).
1200 feet of crest gates on the Spillway.
6 new tainter gates to the existing gate structure.
In evaluating alternatives, BV had to balance competing priorities. They go beyond just reducing upstream flood-reduction benefits and downstream impacts. They include all the factors shown below.
From BV presentation to CWA on 2/10/2021
Metrics that engineers and partners will use to evaluate alternatives and success include:
From 2/10/2021 presentation to CWA Board. U/S and D/S stand for upstream and downstream.
According to the BV presentation, some positive benefit revealed by the work to date include:
Benefits Revealed To Date
Engineers found that the peak of floods from Buffalo Bayou would arrive downstream much faster than water from the Upper San Jacinto Watershed above the Lake Houston Spillway. This means the peaks would not arrive on top of each other. That’s good. It helps mitigate downstream impacts.
The recommended alternative would reveal a positive benefit/cost ratio and not adversely affect downstream structures.
The recommended alternative could turn a 100-year flood into a 25-year flood.
Engineers based the flood reduction benefits on a 100-year flood, not another Harvey.
How Final Decision Be Made
The engineers and partners will consider both cost and non-cost factors in making final recommendations.
Type of Crest Gate Recommended
BV is recommending an Obermeyer gate, though they have not detailed how it would be installed. Water Power and Dam Construction Magazine says, “The Obermeyer spillway gate system is most simply described as a row of steel gate panels supported on their downstream side by inflatable air bladders.” The air level in the bladders control water levels by raising or lowering the bottom-hinged steel panels.

The Lone Star Groundwater Conservation District (LSGWCD) board once again deferred action on subsidence at its three-hour board meeting on 2/9/2021. The ostensible reason: public confusion on the issue, although that confusion may have been caused by the District’s own staff.
Several board members also launched ad hominem attacks against critics, alleging they were deliberately spreading misinformation about the board’s position on subsidence. They demanded public apologies from critics after the District’s own staff made misleading presentations.
Confusion Starts when General Manager, Counsel Fail to Articulate Real Issue
Reiter’s lack of specificity teed up a wandering, confusing and mind-numbing 90-minute presentation by Stacy V. Reese, LSGWCD’s General Counsel.
She designed the presentation to address one of the criticisms leveled against the board by critics, i.e., that a potential violation of the Open Meetings Act had occurred. According to LSGWCD watchers, LSGWCD’s board never openly authorized Beach to make that statement, which seemed to state a conclusion the Board had reached. That raised the questions, “Who authorized the statement and when?” But those were not the questions Reese addressed.
Reese’s Presentation a Masterpiece of Misdirection
Without mentioning Beach’s statement upfront or accurately summarizing critics’ concerns, Reese then tried to show that LSGWCD had investigated subsidence since 2017. But everyone already knew that. And that made a presentation which took up about half the meeting largely irrelevant while the audience drifted away.
Instead of addressing who authorized Beach’s statement and when by reviewing the LSGWCD January 12th meeting and the GMA-14 January 20th meetings, Ms. Reese instead discussed other board meetings and presentations dating back to 2017. Repeatedly skipping forward and back in time and between LSGCD and GMA 14 meetings, her presentation included so much irrelevant information, it became impossible to determine the board’s position on subsidence. One understood only that they had previously discussed it.
Not until two hours and sixteen mininutes into the meeting does Ms. Reese allude to Mr. Beach’s statement to GMA-14 about rejecting subsidence as a metric in DFCs at the bottom of a slide with eight bullet points. But she summarizes the slide in one sentence: “We’re adapting to a subsidence statement.” In other words, she shows one thing and says another.
If you didn’t know that the real issue was Beach’s statement, you might conclude from Reese’s presentation that the board was, in fact, supportive of including some sort of a subsidence statement in Desired Future Conditions. That’s the opposite of what Beach said.
Laying the Groundwork for Backpedaling?
Ms. Reese did, however, lay some groundwork for a possible reinterpretation of Beach’s statement. Although she didn’t say it outright, she implied that measuring subsidence was unnecessary because it varies with groundwater pumping rates. While a correlation does exist at times between the two variables, the assertion masks two important points:
First, without measuring subsidence, you cannot calibrate the accuracy of groundwater-pumping models.
Second, groundwater levels are reversible; subsidence is not.
The latter point deserves explanation.
Groundwater Levels Reversible; Subsidence Not
The amount of groundwater depletion depends on pumping and recharge rates. Those can vary annually depending on usage and rainfall.
But while water-well levels can rebound, subsidence cannot. Subsidence lasts forever. Once clay collapses, it stays compressed. It’s like trying to re-inflate a brownie that you’ve smashed with a sledgehammer.
Not Adopting a Subsidence Metric Would Allow Board to Defer Action on Groundwater Withdrawals for Decades
Putting these facts together, you can see how a LSGWCD board intent on unlimited pumping could cause lasting subsidence and severe damage to homes throughout the region. In a 70-year plan, they could argue through Year 60, for instance, that aquifer levels would bounce back. Without a subsidence metric in place as a check on pumping, they could continually kick the can down the road. They could say year after year that they will change regulations at some point before Year 70 to restore aquifer levels to their targets.
Mr. Beach stated this explicitly during the board meeting. At approximately 2:31 into the video, he says, “We can incorporate subsidence in the future…”
At 2:32, Jim Spigener, LSGCD’s Treasurer says it, too. “It feels like there is a rush to do something. But DFCs are a 70-year process. The danger is that we do something in the heat of a political storm and it’s the wrong thing. We’re not in any hurry to figure out how to do this right. We’re not going to figure this out in a month.”
Righto! Ms. Reese’s presentation must have put him to sleep, too. According to her, LSGWCD has worked on this since 2017.
More Questions than Answers Come from 3-Hour Meeting
Reese’s inventory of subsidence discussions skips from LSGWCD board meetings in May and June of 2020 to the GMA-14 meeting on January 20, 2021, leaving a critical six month gap. (See 2:16 in video.)
Without speculating on the motives of individuals, I would point out that actions speak louder than words. The inability or unwillingness of highly intelligent people to clearly articulate issues and address them in a straightforward manner raises many questions.
Why?
Why delay?
Why defer action?
Why not clarify the differences between measuring aquifer depletion and subsidence?
Why not elaborate on Beach’s statement for video posterity?
Why spend 90 minutes rehashing old board meetings and not one minute articulating a clear subsidence goal?
Who does the LSGWCD board represent? Residents or Quadvest?
These are important questions. Much depends on them. Perhaps even billions of dollars in potential damages.
Types of Damage Subsidence Can Cause
Differential subsidence across a county can cause bowls to develop in the landscape, such as near Jersey Village, which increases flooding. (See subsidence map below.)
The subsidence map below also shows something else. At the rate LSGWCD wants to pump, it could cause southern MoCo and northern Harris Counties to sink two feet relative to the dam at Lake Houston. Picture tilting a full bathtub two feet. Something will get wet!
Models show that excessive groundwater pumping in MoCo could create 3 feet of subsidence in Kingwood compared to 1 foot at the Lake Houston Dam.
Damage to infrastructure such as roads, sewers and buried utilities
Foundation, sidewalk, driveway, roof, and brickwork damage
Cracks in plaster, wallboard, flooring, ceilings, windows, and moldings
Doors and cabinets that refuse to open or shut properly
In some cases, homes may not even be repairable.
Slow Rate of Subsidence Masks Magnitude of Problem
The biggest problem with the subsidence problem? With a few exceptions, such as fault-line triggering, it happens over such a long period of time that many homeowners will never fully experience it.
Median duration of homeownership in the U.S. is 13 years. But in The Woodlands and Houston, owners typically stay in a home just 10 years.
At that rate, most people might not notice subsidence. I’m an exception, I’ve lived in my house almost 40 years. Stick around that long and you get a true feeling for the cost of subsidence. I’ve had my foundation leveled twice; my driveway repaved twice; my sanitary sewer lines repaired twice; my doors and windows replaced once; and my walls, cabinets, and ceilings repaired multiple times.
You don’t need to remind me about the true cost of subsidence.

Today, at 5:52PM, Harris County Commissioners Court unanimously approved three flood-control measures affecting Kingwood. The measures included approval to negotiate engineering contracts for improvements to the Kingwood Diversion Ditch and Taylor Gully. The third approval involved purchase of Woodridge Village from Perry Homes to build a regional floodwater detention facility in Montgomery County.
The City of Houston will purchase 77 acres of the property outright for a wastewater treatment facility. The City will then pay for its half of the remaining Woodridge property by trading land that the Flood Control District can use to reduce the cost of flood mitigation projects elsewhere.
Neither the City nor County have yet announced a closing date for the Woodridge purchase.
Seventeen months after Imelda, families in Elm Grove and North Kingwood Village will sleep easier tonight, knowing they are one HUGE step closer to safety.

Three and a half years after Harvey, many flood victims are still not “getting over it.” Physically, financially, and emotionally. I’ve interviewed people who:
Can no longer sleep during rains.
Break down crying when they attempt to retell their experiences.
Exhausted their life savings, 401Ks, and kids’ college funds trying to rebuild homes.
Claim they’re “past it” with thinly disguised rage in their voices.
Turn every conversation toward their losses.
You can’t just tell such people to “get over it; move on with your life.” That simply angers them and drives a wedge between the two of you.
Residents trying to escape as Harvey’s floodwaters rose into Kingwood Village Estates, a senior living center. 12 residents died as a result of Harvey. Six from injuries sustained during evacuation and six from stress after returning to find their homes destroyed.
So, what do you tell them? The following may help.
The website Medical News Today cautions, “Trauma can have long-term effects on the person’s well-being. If symptoms persist and do not decrease in severity, it can indicate that the trauma has developed into post-traumatic stress disorder (PTSD),” a condition that afflicts approximately 6.8% of the U.S. population at some point during a person’s lifetime.
According to Janice Costa, one of Kingwood’s leading psychotherapists, “The people whose homes flooded definitely experienced trauma. Some developed PTSD and some didn’t for various reasons. “Trauma often goes against a person’s beliefs,” says Costa. For instance, the belief that you’re safe in your own home. “People react differently to traumatic events. For instance, neighbors who lived through Harvey might respond very differently to the same event,” said Costa.
“Trauma can be caused by something a person sees, physical or sexual abuse, an act of nature, the list goes on,” says Costa. “Many people who go through trauma wish they could just get over it. Some people resolve trauma without professional help, but many live with the effects until they get help.
Costa suggests that several popular treatments can help resolve trauma. They include:
Cognitive Processing Therapy (CPT) works on the basis that the way we think and interpret life’s events affects how we behave and, ultimately, how we feel.
Trauma Resolution Therapy (TRT): Desensitization to the traumatic event occurs as the client systematically faces and works through the memory repeatedly.
“One of the keys in treating trauma and PTSD is to emotionally share the experience with a person in the emotional depth that they experienced the trauma.”
Janice Costa, Psychotherapist
This, of course, works best with those who have good support networks. One of the risk factors for developing PTSD is having little support after the trauma. Other risk factors include:
Previous trauma
Physical pain or injury
Dealing with other stressors at the same time, such as financial difficulty
Previous anxiety or depression
After going through TWO of the worst floods in North American history in the last 3.5 years, I’m sure we all know people experiencing several of those who could use help “getting over it.”

1260 Days after Hurricane Harvey and 509 since Imelda

“At this time we can’t support the use of DFCs for subsidence in Montgomery County,” said James Beach, an engineering consultant for LSGWCD.
It’s unclear who authorized the consultant to make this statement. Those who follow LSGWCD meetings cannot remember the board discussing such a statement in any open meeting.
Bad Timing
This comes two monthsbefore a deadline to finalize DFCs for the entire GMA and two years after the debate about subsidence started. Since 2018, LSGCD and GMA 14 partners have debated various groundwater withdrawal/subsidence scenarios.
Run D was the most popular scenario for a long time. It called for leaving 70% of groundwater in place and causing no more than 1 foot of subsidence. However, withdrawing 30% of groundwater produced far more subsidence in Harris County.
The same models showed 2.5 feet of subsidence in south Montgomery County.
GMA 14 covers most of southeast Texas. It includes 19 counties clustered into 7 groundwater conservation districts. Rules adopted by the group apply to every conservation district and county in the area.
Members of GMA 14
LSGWCD has argued in favor of virtually unlimited groundwater pumping ever since its board became elected. Quadvest, a large, private water producer in Montgomery County successfully backed candidates running for the LSGWCD board on a platform of “restoring affordable water.” Both the Board and Quadvest have argued ever since – contrary to scientific evidence – that subsidence is not an issue in Montgomery County. They even produced a study (Phase One) to prove the point. It basically amounted to a survey of scientific literature mashed up with public comments.
Compaction data of various aquifers in Montgomery County.
Not mentioning well-known limitations on use of models for Montgomery County aquifers.
Focusing more on subsidence in Harris and Galveston Counties than on subsidence in Montgomery County.
The HARC Study also points out limitations on the use of data in LSGCD’s Phase One study. For instance, the latter was:
Primarily a survey of scientific literature, not conditions in Montgomery County.
It didn’t discuss drought.
Nor did it discuss oil and gas production.
It drew unjustified conclusions from limited data.
The language was imprecise and subjective.
It relied more on public comment than scientific data.

Two Subsidence-Related Items On LSGWCD Agenda for Tuesday
14. Receive information from District’s technical consultants regarding subsidence studies and/or discussion regarding the same –Samantha Stried Reiter and/or District’s technical consultant(s)
a) Discussion, consideration, and possible action to approve Subsidence Study Phase 2 Scope of Work.
15. Groundwater Management Area 14 – update the board on the issues related to joint planning activities and development of desired future conditions in GMA 14 – Samantha Reiter and/or District’s technical consultant(s)
a) Discussion, consideration, and possible action on any items related to Lone Star GCD’s proposal(s) to and/or participation in GMA 14.
Re: the second point, a water expert I queried said there is no way LSGWCD can opt out of GMA 14. The reference is likely to whether they want to participate financially with other groundwater conservation districts in funding the operations of GMA 14.

The New York Times, Associated Press, France 24 and IndiaToday have reported a freak flash flood in northern India. It happened near the Himalayas after a portion of a glacier broke away and released pent up water.
The Times said, “Unconfirmed videos on social media showed violent surges of water heading down mountain gorges, washing away bridges and what looked like hydroelectric structures.”
Associated Press reported that the flood killed at least 9 people. They reported 140 missing. “The flood was caused when a portion of Nanda Devi glacier broke off in the Tapovan area of the northern state of Uttarakhand on Sunday morning. A video shared by officials and taken from the side of steep hillside shows a wall of water surging into one of the dams and breaking it into pieces with little resistance before continuing to roar downstream,” said the AP story.

Preliminary engineering and final design services for improvements to:
Taylor Gully
Kingwood Diversion Ditch
Purchase of Woodridge Village to build a stormwater detention basin in Montgomery County.
In case you plan to watch the meeting, all three items fall under Harris County Flood Control District (HCFCD). Unless commissioners take items out of order, HCFCD projects usually come second on the agenda after Engineering. Below: exact text of each agenda item.
Agenda Item Text
Item 79:
Recommendation that the Harris County Flood Control District be authorized to negotiate an agreement for engineering services with IDCUS Inc. to provide preliminary engineering and final design services for improvements to Taylor Gully on HCFCD Unit G103-80-03.1. (San Jacinto River Watershed, Bond ID F-14, Project ID G103-80-03.1-E001, Precinct 4).
Item 82:
Recommendation that the Harris County Flood Control District be authorized to negotiate an agreement for engineering services with Neel-Schaffer, Inc. to provide preliminary engineering and final design services for improvements to the Kingwood Diversion Channel on HCFCD Unit G103-38-00. (San Jacinto River Watershed, Bond ID F-14, Project ID G103-38-00-E001, Precinct 4).
If purchased from Perry Homes, HCFCD will swap part of Woodridge Village – the northern 77 acres of the 268 total – with the City of Houston. The City wants to build a wastewater treatment plant there and has negotiated with the County to swap land elsewhere in the City that HCFCD can use to reduce the cost of flood mitigation projects. The land reportedly includes parcels along Halls and Greens Bayous. This swap represents a win/win that helps protect more people throughout the City and County.
Looking north, at most of the 268-acre Woodridge Village Property. Road connects to Woodland Hills Drive new Kingwood Park High School out of frame on left. City is interested in portion at top of frame. Flood Control would use the rest for mitigation.
Scope of Engineering Studies Still Unclear
Contracts for the engineering studies have not yet been negotiated. However, we do have clues in the Kingwood Area Drainage Assessment final report about what these projects might include. Last October, HCFCD talked about:
Widening and deepening Taylor Gully to increase conveyance and/or building the detention pond in Woodridge Village, which empties into Taylor Gully. So Woodridge and Taylor Gully are related; what happens with one will affect the other.
Widening the Kingwood Diversion Ditch all the way from St. Martha’s Catholic Church at the county line to the San Jacinto West Fork. The Diversion Ditch project also included building a detention pond to ensure no adverse downstream impacts. Finally, the Drainage Assessment recommended splitting the ditch near Deer Ridge Park. The split would convey part of the floodwaters straight to the West Fork instead of routing all through River Grove Park via a circuitous route that takes them under Woodland Hills Drive which has washed out in the past.
Red line is Bens Branch. White Line is Kingwood Diversion Ditch. Green line shows where Kingwood Area Drainage Assessment recommended splitting flow as it approached West Fork at bottom of frame. Detention pond location not yet finalized.
No Recommendations Certain Yet
Nothing is certain yet. Commissioners Court deferred the Woodridge Village purchase five times last year – in April, May, July, August and September.
And as for the engineering work, a close reading of the text above shows that HCFCD has not yet negotiated contracts. HCFCD simply wants permissionto negotiate the agreements. “Once we receive authorization to negotiate the agreements from Commissioners Court, we can meet with the consultants and develop the scope, schedule, and budget,” said Matt Zeve, Deputy Executive Director of HCFCD.
Regardless, this is good news and welcome progress for flood-weary Kingwood residents still struggling with recovery. These projects put us three steps closer to solutions.
