City Starting to Excavate Bottlenecks Under Kingwood Drive

For more than a year, HCFCD has excavated Ben’s Branch in four different phases. However, significant sediment remained under the Kingwood Drive Bridge. That’s property owned and maintained by the City of Houston. And now they are excavating that to eliminate a bottleneck. Such bottlenecks can back water up, damaging homes and businesses.

The excavation also affected the area between the two halves of Kingwood Drive.
Sediment will drain and dry before being removed from the banks.

According to Sarman, who talked with the construction manager, after the crew completes work here, it will remove sediment from the bottleneck at the Kingwood Diversion Ditch next to the fire station on Kingwood Drive.

These are little things that make a big difference to people who previously flooded. And there were plenty of them along Ben’s Branch, especially in the Town Center Area. Some businesses still haven’t recovered. The shopping center north of these photos is still largely vacant thanks to catastrophic flooding during Harvey and a ditch whose conveyance was severely reduced, in part, by bottlenecks like this one.

Thanks go to Mayor Pro Tem Dave Martin and his staff at the District E council office.

Atlantic Basin Heating Up with Potential Tropical Activity

As we approach the 4th anniversary of Hurricane Harvey, the Atlantic basin is currently heating up with tropical activity. As remnants of one hurricane washing across New England, two more areas of concern move toward the Northeast. A third is heading toward the northwest Caribbean. It’s still too early to tell exactly where these storms will make landfall. But the presence of so many tropical disturbances signals the need to stay alert to daily weather forecasts.

Each of these storms has a 40-60% chance of tropical formation.

Five Day Outlook for Tropical Activity

8 PM outlook on 8/23/2021 indicates the storms heading toward the NW Caribbean have a 50% chance of tropical formation in the next five days. That’s up from 30% this morning.

Retreat of High-Pressure System Over Texas

National Hurricane Center (NHC) forecasts a tropical wave over the eastern Caribbean Sea will form a broad area of low pressure over the southwestern Caribbean Sea by late week. Thereafter, environmental conditions favor gradual development while the system moves west-northwestward to northwestward over the northwestern Caribbean Sea.

In addition to that, another major low pressure area over Mexico and the Bay of Campeche could move into the Gulf by this weekend though no tropical activity is forecast at this time.

Note massive low pressure system moving into Gulf.

Jeff Lindner, Harris County meteorologist, warns that as the high pressure ridge currently sitting over Houston begins to retreat north by Wednesday, “A series of tropical waves and disturbances will move from east to west across the US Gulf coast and into coastal TX from mid week onward. With a significant influx of Gulf moisture, showers and thunderstorms will return as early as Wednesday across much of the area and last likely into next week. Locally heavy rainfall will become an increasing threat by late week and this weekend with tropical moisture firmly in place over the region.”

Historical Norms for Late August

NOAA’s Climate Center shows that the projected path of the current areas of concern should follow historical norms for this time of the year.

This is one of the reasons why.

Current sea surface temperatures in the Gulf are running 1.5 to 2+ degrees degrees above normal for the next seven days, with the warmer areas nearer the Texas Coast.

Historical Intervals Between Major Hurricanes

NOAA’s Climate Center shows the average interval for major hurricanes striking the Houston area is about every 25 years.

NOAA’s Climate Center also tracks the average return period for MAJOR hurricanes at various points along the coastline. They show that the Houston area can expect on average one major hurricane about every 25 years.

Of course, a hurricane doesn’t have to be major to cause major damage. Allison and Imelda were just tropical storms. And averages are just that – averages. Ike in 2008 and Harvey in 2017 each attained major hurricane status and hit Houston within 9 years of each other.

HCFCD Issues Update on Bond Spending In Advance of Harvey’s Fourth Anniversary

Last Friday, Harris County Flood Control District (HCFCD) issued a 37-page report detailing spending on 2018 flood-bond projects to date. It was attached to the agenda for the Harris County Commissioner’s Court meeting on Tuesday, August 24, 2021.

Total spent by watershed from all sources as part of HCFCD bond program. One of ten similar maps in the report.

Background

Late this week and early next will be the fourth anniversary of Harvey’s four day rampage through the Houston area. The storm broke so many records that NOAA retired its name. A year later, still reeling from the storm’s effects, Harris County voters approved a $2.5 billion bond issue to catch up with decades of chronic underfunding for HCFCD.

Since then, the rate of spending on flood mitigation projects has more than doubled. And the rate will accelerate even more as more projects move from engineering to construction.

High-Level Findings

Three years into a 10-year bond, HCFCD has spent slightly more than 30% of the money. That puts them exactly on track time-wise.

Among other things, the full report released last Friday shows that:

  • 175 of 181 bond projects have been initiated
  • $251 million in contracts have been awarded to engineering companies
  • $552 million in contracts have been awarded for construction of capital improvements and repairs.
  • 27 projects have completed, removing 11,000 homes from 100-year floodplains
  • Another 660 buyouts have been completed with another 662 in process.

Back in 2018, the Harris County Flood Control District (HCFCD) vowed to be open and transparent with bond funds. This report shows how, when, and where it spent the public’s money.

Accurate Snapshot of Progress

Until now, HCFCD’s website was the primary means for communicating with the public. But information was scattered across hundreds of pages and updates took place incrementally. That meant information on some watersheds was current and others could be months old. That made it difficult to get an accurate snapshot of progress.

To rectify this problem, HCFCD last week released the first in a series of new monthly reports. It gives everybody in every watershed information about what’s happening that affects them…at a glance.

Types of Information Included

The first report is 37 pages and tracks spending through the end of July 2021.

It’s broken down into a series of sections that include:

  • An introduction that summarizes active bond projects, grants, local partner funding, buyouts, contracts awarded, projects completed, community engagement, floodplain preservation, selective clearing and turf establishment
  • A visual timeline that tracks the progress of projects by month and year
  • Key performance metrics
  • Recent news
  • A GANNT chart showing the stages and progress of every single project approved by voters
  • Eight maps showing cumulative spending from different sources of funding
  • Two maps showing the location and spending to date on all active construction and maintenance projects in the county.

The Ultimate Go-To Doc on Where Your Money Has Gone

This is the ultimate go-to document for everyone who wants to know what’s happening near them. And HCFCD vows to update it monthly.

If you compare this to articles I previously published on funding, keep in mind that this data includes:

  • Four more months of spending
  • Only spending starting August 2018 (approval of the bond fund).

So numbers may vary from posts you see on ReduceFlooding’s Funding page. I also included historical spending going back to 2000 to help put the current spending in context.

Replacing Fear with Facts

All in all, HCFCD’s monthly spending reports will advance the public dialog. It will be good to have discussions based on facts, not just fear.

Flooding is one of the most terrible things that can happen to someone. It produces lasting trauma and alters the trajectory of lives.

To complicate matters, not many people understand what a flood control project is. They may see a jogging trail in a park and not realize it is a massive flood detention basin. They may not realize that a channel through their neighborhood has been widened. And they likely don’t know how to track historical gage data to see if their neighborhoods are flooding from bayous or streets.

This report won’t solve all those problems. But it will go a long way toward helping people understand they have not been forgotten.
