On October 28, Royal Pines flooded a neighbor on less than an inch of rain. Two months later, on December 29th, the same thing happened again. The video below provided by the homeowner shows the volume of water funneled across her property by the developer.
Video from NW corner of Royal Pines
This video and the previous one from October demonstrate the dangers of clearcutting and redirecting drainage without first constructing sufficient stormwater detention capacity.
The homeowner who shot the video lives adjacent to the left border in the photo below. Royal Pines has apparently sloped its property toward that corner where contractors will eventually build a stormwater detention basin.
Looking N across Royal Pines. This and other photos below taken on 1/3/23.
Land now slopes toward where video was filmed at left corner. But that area used to slope in the opposite direction. See details below from the USGS NATIONAL MAP and the developer’s plans.
Green arrow on left shows location of homeowner’s property. Red X within V-shaped contour shows exact location of low point (graph on right) before clearing and grading the land.
There used to be an 8-foot drop east of the homeowner’s property. But now, instead of water flowing directly north to White Oak Creek, it flows northwest.
The general plan for Royal Pines (below) shows the same V-shape in the proposed detention basin (upper left). The line represents the edge of the floodplain and confirms that the developer A) knew about the slope and B) changed it.
Royal Pines General Plan.
Silt Fence, Trench Ineffective Against That Much Water
The video above and the photos below show that silt fence makes a terrible dam against even small rains funneling toward a point from such a large area.
Exercise in futility. A series of silt fences have done little to catch and slow the water...or the silt. Note erosion deposited in woods.Looking south. The developer apparently tried to divert runoff racing toward the homeowner with a trench. But erosion from the barren land rapidly filled it in. Runoff also collects at the entrance to Royal Pines. Looking ENE from the entrance at the northern end of West Lake Houston Parkway.
Unfortunately, the developer plans to build homes there, not another detention basin.
0.88 Inches of Rain Fell in Two Hours
The graph below from the Harris County Flood Warning System shows that .88 inches of rain fell in the two afternoon hours before the homeowner shot the video.
Homeowner shot video after first two bars on left.
The table below shows that that much rain in two hours constitutes less than a 1-year rainfall event.
Atlas 14 rainfall probabilities for this area.
That’s consistent with actual observed events and climate records. According to the National Weather Service, on average, we can expect rainfalls greater than 1 inch 14 times per year in Houston. That’s about once per month.
Woodridge Village Revisited
The Montgomery County Engineer’s Office has reportedly asked the developer’s engineering company to revise its plans. The homeowner says that according to the engineer’s office, not even a 6-7 foot tall berm around that portion of the property would be enough to stop all the water flowing in that direction.
So, what lessons can we learn from this example? As with Woodridge Village, don’t clear and grade this much land before constructing detention basins!
The first sentence of Section 11.086 of the Texas Water Code states that “No person may divert … the natural flow of surface waters in the state, or permit a diversion … to continue, in a manner that damages the property of another…”

On January 9, 2023, FEMA released a Simplified Procedures policy for Public Assistance grants to speed up recovery for applicants. Small projects are now defined as those up to $1 million.
The new policy should reduce administrative burdens and enable communities to recover more quickly after presidentially declared events by streamlining documentation requirements.
FEMA will accept estimates with summary information and the applicant’s certifications for damage and work, instead of requiring applicants to provide full or detailed documentation.
FEMA Press Release
FEMA conducted a review in 2020. It showed that if a $1 million threshold were applied, 94 percent of projects would be considered small and help put additional recovery dollars in the hands of applicants faster and accelerate closure of projects.
FEMA intends to continue adjusting the threshold annually to reflect changes in the Consumer Price Index. It also intends to review the base threshold every three years.
The new policy is not directly aimed at individuals, but at state and local governments and certain types of private nonprofit organizations. Public Assistance grants cover such things as:
Disaster-related debris removal
Emergency protective measures
Repairs to damaged or destroyed infrastructure (i.e., roads).
FM1010 Washout during Harvey at Rocky Branch in Plum Grove near the East Fork. Still not repaired after 5.5 years.
Depending on repair cost and other factors, the road washout above is an example of the type of project that might benefit from the new policy. However, it’s not clear whether the simplified procedures apply retroactively to damage from past disasters or only future disasters. More details will follow.
Applicant has legal responsibility to perform the work
Cost is reasonable.
Once FEMA and the state review and approve the government agencies’ or nonprofits’ RPAs, applicants work with their FEMA representative to develop a damage inventory.
FEMA obligates funds to the state once a project meets Stafford Act eligibility requirements. The state is the official recipient of FEMA federal assistance. The state is then responsible for disbursing the money to applicants.
FEMA will hold a series of webinars in coming weeks to explain more about the simplified policy. Additional details are not yet available.
Getting aid to people faster after a disaster is necessary. This is a very complex subject. I wish all forms of disaster relief, including hazard mitigation, could be simplified. We’re still waiting on the Harris County, the GLO and HUD to agree on a plan for spending $750 million in mitigation funds related to Hurricane Harvey – 5.5 years after the event!

Harris County Commissioners Court approved a motion on 1/10/23 that will change the formula for scoring future flood projects. It gives two thirds of a potential project’s score to population density, building density and social vulnerability, but only 20% to flood risk and nothing to actual flood damage.
Stacking the Deck
The new formula could be used both to compare and eliminate projects. With only 20% of a project’s score determined by flood risk, fixing minor flooding inside the Beltway could soon take precedence over fixing severe flooding outside the Beltway. The formula provides only the illusion of transparency and fails to ensure fairness.

During Hurricane Harvey, the highest flooding in the County occurred outside the Beltway along the San Jacinto River, Spring Creek and Cypress Creek.

Regardless, despite being the largest watershed in the county and one of the most heavily damaged, few flood-mitigation dollars have come to the San Jacinto Watershed.
Since Harvey, 4.6 more flood-mitigation dollars have gone to the Brays watershed than the county’s largest, the San Jacinto.
Brays is the county’s most populous watershed. It’s also where Commissioner Ellis lives. Could that have anything to do with the factors and weights in the new formula for scoring future flood projects? They include:
45% Project Efficiency
15% Resident Benefits
30% Structure Benefits
20% Existing Conditions
20% Social Vulnerability Index
5% Long Term Maintenance Costs
5% Minimizes Environmental Impacts
5% Potential for Multiple Benefits
This new formula omits consideration of damage, risk reduction and partnership funding. Partnership funding has provided approximately one third of all Flood Control District funding since 2000. The new formula gives the most weight to building and population density incorporated in the Project Efficiency formula (project cost divided by # residents and structures benefitted). This 15-page PDF explains how projects are scored within each category above.
Other Problems with Formula
The formula for scoring future flood projects, proposed by Precinct 1 Commissioner Rodney Ellis has many other problems. It also:
Does not differentiate between types of structures while giving them almost a third of the weight. Thus, a mobile home counts for as much as a hospital or college.
Gives no weight to protecting critical infrastructure such as bridges, hospitals, grocery stores, wastewater treatment plants, etc.
Gives 20% weight to social vulnerability, but ignores the severity of flooding. Thus a low-income home with one inch of flooding counts as much as an entire condo complex swept away by 22-foot deep floodwaters.
Makes awards more subjective because HCFCD has no way of estimating how many people live in apartment buildings or homes. HCFCD can count buildings in satellite photos, but the number of residents benefitted will always be a guess. Census tracts do not follow floodplain boundaries.
Undermines efforts to prevent flooding, as opposed to correcting it after people are damaged. Prevention, such as HCFCD’s Frontier Program, is always more cost effective in the long run.
Places 45% of the weight on cost data that has not yet been determined when deciding whether to explore projects further.
Ellis’ proposal passed 3-1 yesterday. Commissioners Rodney Ellis, Adrian Garcia, and Lesley Briones voted for it. Commissioner Tom Ramsey voted against. County Judge Lina Hidalgo was absent. Commissioner Ellis ran the meeting.
To see the discussion on Ellis’ proposal, click on “Departments 2 of 2” in the meeting video and scroll forward to 3:03:53. The discussion lasts 16 minutes. Below is a summary of key points and their time codes.
Summary of Debate with Video Timecodes
Ellis positions his proposal as a “transparency measure.” 3:04:10
Dr. Tina Petersen, head of the Flood Control District describes it as a “clear, consistent and equitable basis” for comparing projects that the flood control district is undertaking. 3:04:53
Precinct 3 Commissioner Tom Ramsey says “criteria and frameworks are not necessarily a bad thing,” but then expresses a list of concerns about the proposal, none of which are addressed later in discussion. 3:06:19
Petersen responds that it’s “not perfect.” She says, “there’s no reason we can’t continue to refine this tool.” It’s very “general.” It let’s us “use what we have as a basis for comparison and continue to look forward to opportunities to refine” the tool.
Precinct 2 Commissioner Adrian Garcia asks whether the proposal will add costs or time to projects. 3:11:00
Petersen says no. “The framework should not require additional costs as long as we don’t look back.”
New Precinct 4 Commissioner Asks Probing Questions
New Precinct 4 Commissioner Briones then asks “how often will it be updated?” 3:13:20
Petersen replies, “We’re not considering making any changes to the framework.” She describes the primary uses as: comparing projects and determining which are eligible for funding from the Flood Resilience Trust.
Briones asks whether the framework incorporates “severity of flooding.”
Petersen points to the “efficiency” metric as the closest thing because it incorporate the number of people and structures benefitted. But Petersen sidesteps the point of the question about “depth of flooding” raised by Ramsey earlier. 3:14:25
Briones questions why partnerships are excluded.
Petersen responds that the framework was designed for use with the flood resilience trust, on projects where partnership dollars were no longer considered a possibility. “It was intended to be a backstop for projects that do not have partnership funding.” Petersen does not mention $750 million in HUD/GLO dollars pending final approval.
Briones next asks whether the framework will provide a threshold for making go/no-go decisions on projects. 3:15:40
Petersen replies, “I want to be clear. It will be used for determining whether a project is eligible for flood resilience trust funds.”
At 3:19:30, Ellis quickly closes debate before someone asks for clarification. The measure passes.
Debate Filled with Unresolved Contradictions
Petersen sidestepped Brione’s tough questions about severity of flooding and the eliminating projects. At one point, Petersen said it was “only a point of comparison.” Later, she said it would determine project “eligibility.”
She also equivocated in her response to Ramsey’s concerns. At first she implied the framework was a first step. Later she said that she didn’t plan to change it. Even though the framework is intended for future projects, most of Petersen’s answers related to the past.
