1/7/2025 – In the week after a holiday lull, Northpark construction is ramping back up and should reach some milestones later this week. According to the Lake Houston Redevelopment Authority website:
A paving crew will begin pouring concrete for new lanes beginning Friday January 10th in front of PNC Bank between US and Loop 494 on the north side of Northpark.
Another crew will demolish the existing eastbound lanes of Northpark from Kings Mill to Russell Palmer Road.
In other news, crews will continue:
Installing reinforced concrete box culverts between Caliber Collision and the Extra Space Storage facility to accommodate new westbound access roads.
Switching water services from the Porter Special Utility District to the City of Houston.
Grading the area for a sidewalk between Loop 494 and US59 on the north side of Northpark.
See the pictures below, all taken on Tuesday morning, 1/7/25.

New westbound lanes and a sidewalk will go in the area being prepped to the right of existing traffic.Looking E toward 494 from same location.

The first three shots below show the culvert installation east of 494 from different angles.
Looking W toward 59. Drainage work from Caliber Collision (lower right) has reached the area between Dunkin’ Donuts and Public Storage.
This will be the area where two westbound surface turn lanes split off from traffic continuing over a bridge that spans Loop 494 and the UnionPacific Railroad Tracks.

1/6/2025 – Before New Year’s Day, I posted about the lack of best management practices (BMPs) at the Foster Elementary reconstruction site in Kingwood. A contractor let sediment-laden runoff escape the site, fill the street and flow into unprotected storm drains. Photos taken yesterday after a storm front passed show that it’s still happening.
Partial List of Sediment Control BMPs for Construction Sites
The EPA considers sediment a major source of pollution. And not following best practices to control it can clog storm drains, channels and streams, raising flood risk. I quote from the Agency’s brochure: “Sediment fills up storm drains and catch basins to carry water away from roads and homes, which increases the potential for flooding.”
To reduce the potential for flooding, the EPA recommends several best practices. They include, but are not limited to:
1. Silt Fencing around the perimeter to intercept and slow down runoff, so sediment can settle before water flows off the construction site.
2. Stormwater-Inlet Protection, such as sandbags, placed around stormwater inlets to capture sediment before it enters the storm drainage system.
3. Sediment Control Logs (Wattles) filled with straw or other materials to capture sediment before it leaves the site.
4. Mulching with organic materials such as straw, hay, or wood chips to help to protect soil.
5. Sediment Basins & Traps to capture sediment from runoff until it settles out of suspension.
6. Erosion Control Mats or Blankets to stabilize disturbed soil and prevent erosion.
7. Stormwater Diversion Channels to direct runoff to sediment-control ponds or a controlled discharge areas.
8. Construction Entrance/Exit Stabilization with gravel to minimize tracking of mud onto roads from construction vehicles.
9. Geotextiles to stabilize soil.
Slight Improvement, But Still Lacking
After the last post, the Humble ISD contractor did add straw wattles (#3 – sediment control logs) in front of the main construction site entrance.
But storm drain inlets remained unprotected. And part of the perimeter lacked silt fence.
As a result, sediment still escaped the site, entered the street, and entered the storm sewer. See the photos below taken by Chris Summers, a local resident and retired commercial photographer, after a recent storm front dropped .84 inches of rain on 1/5/25.
Entrance to construction site shows wattle roll that was not present for previous storm.
While that showed some improvement, other parts of the perimeter still lacked protection and let water escape.
No silt fence.Wattle roll did not cover the critical area, letting sediment laden water escape into storm sewer.Also, inlet not protected with sand bags.
Summers says he took the photos above after the storm front on 1/5/25 passed through.
How much effort does it take to drop a couple sand bags next to a storm sewer inlet? Could it cost much more than coffee and a danish? There’s just no excuse for this.
Sound Off to the School Board
I have already emailed members of the Humble ISD school board and suggest you do, too. We have lots of good contractors in the area that know how to follow best practices.

1/5/2025 – At a Community Resilience Flood Task Force Meeting in December last year, the Harris County Flood Control District (HCFCD) announced that it would be kicking off a new feasibility study in Q1 2025 designed to make half of Harris County SAFER from flooding.
SAFER stands for Solutions for Advancing Flood Mitigation, Equity, and Resilience. The study area includes 11 of Harris County’s 23 watersheds.
HCFCD issued this statement about the study.
Overview of Study from HCFCD
The SAFER Study has the potential to address one of the most impactful threats to the Houston/Harris County region: severe storm events that cause catastrophic flooding.
This study will look broadly across the county and consider not only the effectiveness of large-scale flood mitigation projects within strategic locations, but also how they will function collectively as a system to provide flood mitigation, and the associated benefits, across broad regions of the county.
With the SAFER Study, the Flood Control District will be seeking to:
Identify substantial, wide-ranging flood mitigation across the region rather than depending solely on smaller, incremental projects that address the needs slowly.
Conduct the study in a way that allows the Flood Control District to identify flood risk reduction projects that could be cost-shared with the Federal government and constructed in partnership with the U.S. Army Corps of Engineers (USACE).
Identify project recommendations based on comprehensive benefits, which include social effects and environmental quality, as well as regional and national economic impacts.
Identify opportunities to integrate nature-based solutions.
The study area spans across eleven (11) watersheds within Harris County, including:
Brays Bayou
Buffalo Bayou
Clear Creek
Cypress Creek
Greens Bayou
Halls Bayou
Hunting Bayou
Little Cypress Creek
Sims Bayou
White Oak Bayou
Vince Bayou
The goals of this study effort are to reduce flood risks and strengthen resiliency within Harris County, to be grounded in the principles of equity, to pursue larger transformational solutions with broad benefits, and to better prepare the region to withstand both the flood risks of today and those of the foreseeable future.
The SAFER Study will evaluate traditional flood mitigation measures, such as increasing channel capacity and construction of new stormwater detention basins, as well as new options including large-scale stormwater tunnels, and non-structural measures.
The study will consider social, economic, and environmental benefits and impacts while evaluating flood mitigation effectiveness.
While the Flood Control District will be leading the study, we will be following federal laws, regulations, and guidance applicable for feasibility studies of water resources development projects, such as the SAFER Study.
We will be working with USACE for input throughout the study process to ensure recommendations are developed that follow USACE policy and guidelines.
We anticipate initiating the SAFER Study during the first quarter of 2025.
Saving the Worst Flooding for Last
Twelve watersheds are not included in the study. Among them are two that had the worst flooding in the county during Hurricane Harvey: the San Jacinto and Spring Creek Watersheds.
Chart showing feet above flood stage of 33 gages of misc. bayous in Harris County during Harvey.
So much for the oft repeated promise to fix the worst flooding first. HCFCD did not explain why it is including only half the watersheds.
From Hurricane Harvey through Q3 2024, HCFCD spent $1,444,838,886 on mitigation and maintenance in all of the county’s 23 watersheds, excluding county-wide projects.
Of that total, the 11 watersheds included in the SAFER study have received $1,132,471,139. That’s 78% of the total.
The 12 watersheds excluded from the SAFER study have received only 22% of all HCFCD spending.
Data supplied to ReduceFlooding.com in response to a FOIA request.
Here’s how the forgotten majority looks in a pie chart.
More than half of the watersheds have received less than a quarter of all HCFCD spending since Harvey.
