Reports of Street Ponding

The LIDs’ operator and HOA have received several calls from residents regarding ponding in the streets due to rainfall on and after Sunday, December 2. These reports of street ponding appear to be localized to sections within LID 15 with ongoing home construction activity.

The LIDs’ engineers have explained that temporary street ponding is expected during intense rainfall over short durations. The engineer has received reports that the heaviest rainfall on Sunday, December 2, was approximately 2 inches over 30 minutes. Under those heavy rainfall conditions, temporary street ponding would not be unusual, and that the water should recede once the rain slows or stops.

In the areas impacted during this week’s recent rain events, construction debris or siltation controls may have inhibited the storm sewer system from working at its full capacity. The operator for MUD 128 (as owner of the storm sewer system) is inspecting the storm sewer systems in these areas to confirm they are clear of construction debris or any blockage.

If you are seeing ponded water in the streets that does not recede after the rain has stopped or slowed, please make a note of the location (and take a photo if possible) and let us know through the website (Contact Us tab above). The LIDs will do their best to investigate it promptly, or communicate the issue to the appropriate MUD operators as soon as possible.

After Action Reports

As each LID board moves forward in reviewing its own systems, protocols, and next steps, the information will be posted to each LID’s separate page (tabbed above). Updates to this main landing page will be posted only if they pertain to both LIDs.

Debris Pickup – Final Pass

Fort Bend County will begin its final pass to pick up debris in Riverstone beginning on Wednesday of this week. Please place any remaining debris out between the curb and sidewalk and move any cars that may impede access.

Friday Update

Weather System in Gulf

The LID operators and engineers are keeping an eye on Tropical Storm Nate. At this time, it does not appear that Nate will affect the Texas-area, but the LIDs crews are ready to handle any changes in projected path.

At this time, the LIDs’ detention ponds have the full capacity to receive and store any rainfall that may occur. In addition, the current reading of the Brazos River at the Richmond gauge is 14.06 feet, so any immediate internal rainfall would drain through gravity outfall. As a reminder, at Steep Bank Creek, gravity outfall continues until the Brazos River at Richmond gauge reads above 39 feet. However, the LID operators are continually monitoring the pump station to confirm that all pumps are functional and ready to operate if needed. Finally, we have confirmed that the MUDs overlapping the LIDs have undertaken measures to inspect and clean out storm sewer systems after Hurricane Harvey.

Although the supplemental pumps ordered during Hurricane Harvey have been removed from the Steep Bank Creek Pump Station site, the LIDs operators have confirmed that in the unlikely event of another unprecedented coincidental rainfall event, additional pumps can be delivered and made operational within 48 hours.

After Action Report

The LIDs engineers and operators are reporting that the internal after action reports are almost complete. When they are completed, copies will be posted on this website.

In addition, LID 19 will be releasing a Request for Qualifications for an external, third party review of the following:

  1. Review of Current System – compliance with all regulatory and design criteria
  2. Harvey Response – operations, communications, and recovery
  3. Potential Changes to System and Cost Analysis
  4. Other Suggested Changes
