Brazos River Update – May 31st 10:50 a.m.

Our Engineers (Jones & Carter) and our Operator (EDP) continue to do a wonderful job for us. They are monitoring the elevations of the Brazos River, Jones Creek, and all areas around the District. The Brazos River is projected to peak throughout the early part of the afternoon today, and Fort Bend County and the National Weather Service are still holding to the projection of a Richmond gauge elevation of 53.5-feet. The current level is 53.39-feet. EDP has crews walking the levee around Pecan Lakes and our Southern boundaries. Mason Road at 359 has been closed by TxDOT, and water is visible across the roadway. At this time there is no report of water on the bottom of our levee in any areas, but we will wait for a report from the current crews monitoring the levees.

Along with the Brazos River water level, we are also monitoring the rain forecast. The forecast for today is dry, but a 40% chance of rain is expected for tomorrow, and a 60% chance for Thursday. We will continually monitor this forecast, and EDP will be operating the storm water pump stations as necessary should the District receive any significant rainfall.

Just for an FYI, Fort Bend County OEM accidentally listed Pecan Lakes subdivision as an area not protected by levee in a public service announcement/reverse 911 call. This is incorrect, and the proper authorities have been contacted and notified. They are aware of the incorrect information and this problem is resolved. Residents in Pecan Lakes are now protected by our new levee system.

There is also an area in the back of the Randall’s parking lot that is starting to hold water. The source is from a storm drain near FM 359 tied into the main outfall channel. EDP is on scene and will be putting up barricades to prevent residents from entering or interfering with this area. The water is coming up from the lot, and travelling towards and into the North drainage channel.

A team from Fort Bend OEM and the Texas A&M Robotics team is currently in Pecan Grove and are utilizing aerial drones to survey and document the flooding of the area around the District. The drone will allow us to get a better view and understanding of the overall extents of the flooding around the District.

Fort Bend County OEM is the source of the latest information on the Brazos River flooding, please refer to the OEM website for more information by clicking here. Also, please refrain from sightseeing during this event there are significant safety hazards with walking around areas with high water. Please allow the Emergency Operations teams to keep the community safe, by staying away from high water areas.

Our Operators and Engineers are very busy around here, working to protect our community and keep us dry. They are doing a great job.

Message from Pecan Grove MUD Board

I know you are likely getting questions from friends and neighbors about this flood event. I’ve heard that some might ask questions like “should I be getting sandbags for my home”, or “what roads will be impassable”. The PGMUD levee is design to prevent flooding for a 100 year flood event (and then some by my observations – good job Mr. Engineers) so there should not be any flooding with PGMUD from this event. The National Weather Service is keeping the high water prediction of 53.5’. It would appear the that the water level readings at the Richmond gauge show a trend that may fall short of this prediction. But if the water does get to 53.5’ we do expect to have water up to the bottom of the levee in several areas. The area that we think would be first is near the intersection of Mason Road and FM 359, in the open field west of 359. This area is outside the Pecan Grove MUD levee. If the crest stayed at this level long enough we could see water over 359, but it should not crest over the portion that Pecan Grove MUD paid money to Texas department of transportation (who maintains FM 359) raised for our levee. We do not anticipate the need to deploy the WIPPS (Water Inflated Property Protection System). In the event that FM 359 is inundated with water on the south end, our planned route of access is via Mason Rd, entering the levee at the north end at Farmer Road.

I have contacted Sargent Gobar and Chief Wooley to ensure they are aware of the situation.

Please click here to subscribe to the Fort Bend County OEM website emails for more frequent updates. Also official updates are posted on our website. Please rely on the Pecan Grove MUD official website for reliable information.

Here is some more detailed information from our operator EDP. There are currently no unmet needs. PGMUD Level 2 Emergency Levee Operation was initiated May 28, 2016. All levee gates are closed with the exception of the FM 359 Levee gate. This gate will remain open; only being closed based on local observations of the water level along FM 359. All pump storm water pump stations remain ready in standby. All drainage systems are at low levels within the levee. 2 man teams are rotating through the pump station and conducting levee inspections. As the water levee approaches the bottom of the levee, we plan to deploy four 2 man teams on 6 hour shifts to continuously man the levee, walking the top of the levee conducting visual inspections. The customer call center has been briefed on the situation to improve communication with the public. PGMUD is posting daily updates on the web site. PGMUD also has email burst communication ready in the event an emergency condition should arise.

The Pecan Grove MUD office will be the command center for the levee operations.

As we hope you understand our operator’s first priority is emergency operations. Posting on the website is a priority, but not as high as priority is making sure all of our residents are safe from Brazos River flooding. We do encourage our residents to subscribe to the Fort Bend County Office of Emergency Management update system so that you can get much more frequent information, which you can do by clicking here.

April 21st Update from the President

Below is a picture of the gauge at Jones Creek at FM 359 showing the water level at 80.2 feet at 7:49 AM and a chart of the Brazos River level at the City of Richmond gauge.

EDP checked the drainage systems through the night with no issues found. As of this morning the South pump station has been started to get a proactive start on the impending rain. The current level in the main channel is approximately 1.5 feet above the base of the intake. The Pecan Lakes pump station has not run and the detention pond is at the minimum level. The North pump station is below the bar screen and Oyster Creek is at 6 feet. Bullhead Slough is gravity flowing at this time. All systems are functioning normally with no foreseen problems. EDP is continuing communication with the Fort Bend County Emergency Operations and we will keep you updated as additional information becomes available.

Update from the President

April 19, 2016 at 12:40 PM

Overnight our operator EDP continued to check local drainage system and all of our pump stations. All was normal, with very little overnight rain. Our drainage system remains at low levels with capacity for another rain event. EDP is continuing to communicate directly with the Fort Bend Emergency Operations Center, which is being manned 24/7. It is indicating that the Brazos River peak prediction is lower by about one foot, from 49.5 to 48.5. It is likely that the confidence level of the prediction model has improved. We are expected to receive more rain later today as a trough of low pressure moves in from the west later today and into the night hours. We could see up to one inch of rain with this system.

All MUD facilities are currently on normal power supply, without the need for use of our emergency backup power generators. EDP is monitoring the flow through the Waste Water Treatment Plant. EDP reports there was some minor electrical damage at water plant #2, but the transfer switch to emergency power is functioning. The automation for the generator transfer switch for the north storm water pump station was also damaged, which will require EDP to operate the switch manually, if needed. There was some minor electrical problems with lift station No. 8, but it will function.

The hydrograph below show the current river levels and the predicted levels. The river reached the stage 2 operation level of 42’ at about 11:00 PM last night. All levee gates are closed with the exception of the FM 359 levee gate. The current level on the Richmond gauge is 43.2’, for reference the attached picture of the outfall channel shows the water level at the flap gates, with a water elevation of 73 feet, picture taken about 45 minutes after the river gauge level show below.

EDP will continue emergency levee operation through tonight and likely tomorrow night. If conditions remain unchanged, the next update will be tomorrow morning.

Thank you for your patience while we operate in emergency conditions. We also have posted recent information from WCA about trash collection, which will be collected as normal today for Tuesday pickups.

Don’t forget to sign up for email blasts through the website so you will get notice of updates. And, most important, stay safe and dry.

Chad Howard, President of Pecan Grove MUD

Letter from the President to Our Residents

Thank everyone for your patience today. I hope everyone is safe. We are doing our best to ensure everyone stays dry.

The National Weather Service has updated their prediction of the Brazos River. As of 2:49 PM, the Brazos River is expected to hit Gage Elevation 49.5’ tomorrow afternoon. Currently, Richmond’s Gage Elevation is 30.42’ which is approximately 13 feet higher than 5:45 AM this morning. Due to the watershed conditions and the rain forecasts, the NWS reports to our operator EDP and engineer Jones & Carter that is has a “low confidence” level on this forecast. Therefore, the NWS has issued a range of elevations for the crest. Their current range is Gage Elevation of 46’ to 52’. Our engineers confirm to me that the toe of the levee along the Pecan Grove levee system ranges from 80′ to 84′. At either elevation, our operator EDP will shut the South Outfall (under FM 359) and the Pecan Lakes outfall. Our engineers and operator will be in the District this evening to check some of the external and internal levels.

Afterwards we will send an update on the current levels and what the predicting means for Pecan Grove is we have more information. Although we are in frequent contact, I expect to hear from them with a significant update this evening between 9:00 and 10:00 p.m. Please stay tuned to our MUD website for official District news and updates and be safe.

President, PGMUD

Some local news have been reporting streets into and out of Pecan Grove are closed.  FM 359 is open coming in from 90A.  359 is open and clear coming from the west.  We had a report that Mason south of 99 had high water but we believe it is down now;  please check with Fort Bend County who maintains and operates our roads before venturing out.  Plantation at Bittersweet is now clear.  EDP has three two-man teams out just picking up trash and debris so our storm sewer inlets and system remain as clear as possible.

If customers are out, EDP crews are letting customers know there is no trash pickup today.  We hope you all will help us spread the word to come to the MUD website for official information about conditions.  Please also check with Fort Bend County for conditions as well as the National Weather Service, and stay safe.

UPDATE: District Emergency Preparedness In Action

UPDATED:  Monday April 18 at 11:03 AM

Pecan Grove is experiencing street ponding right now, as you all know.  The north and south drainage channels are flowing by gravity.  EDP is out chasing garbage from cans that were left out in the storms, which are now going into the storm sewers.  As you saw from the prior post, WCA is not able to pick up trash today.  If you have not already moved your trash cans back into your garage, please do so to help us out.

UPDATE: District Emergency Preparedness In Action

UPDATED:  Monday April 18 at 10:31 AM

The District asked our Engineer, Jones & Carter, to explain the graph posted on our Website about the Brazos River.  Jones & Carter tells us the graph is a projected water level of the Brazos River from a gauge in Richmond near the Highway 90A bridge.  The blue line is the actual elevation the River is experiencing, and the purple is the projected level using the current level and expected rainfall within the Brazos River watershed. You can see there are several different action levels (moderate, severe, etc.). The minor flood stage is when the water level is expected to reach 45.

Pecan Grove MUD works closely with the Fort Bend Office of Emergency Preparedness in times like these.  This River level alert is given to all of the surrounding areas to inform us that the water level in the Brazos River is elevated and they need to start preparing. All communities throughout the area have different levels of concern for the Brazos River flooding. Any time the level is expected to reach at least 45, the Pecan Grove MUD Emergency Action Plan goes into to action regardless of where the Brazos River actually is. What this means is that EDP is out at our storm water pump stations, operating them as necessary.  EDP is currently dispatched all over the District, and for now the main focus is on the north storm pump station by the MUD’s Elevated Water Storage Tank.  Oyster Creek is elevated and prohibiting gravity flow from Bullhead Bayou; this makes is necessary to operate the north end storm water pump station.

The biggest takeaway from this chart is that the Brazos River is not expected to peak until tomorrow. When the Brazos starts getting into the 48-49 range, portions of roadways in the Richmond area are blocked from the actual Brazos River flooding. This does not mean the local streets will not flood from local rainfall, which is already being experienced. Once the Brazos River increases in elevation, it will block our main storm water outfalls from draining by gravity and then all storm water pump stations will be required to operate. For reference, the last major flood the Brazos River experienced, the elevation reached around the 50 mark. This event is expected to be 7 inches below that.  The overall elevation of the water will be 4-6 feet BELOW the toe of both of our Pecan Lakes and PGMUD levees.

This is the best prediction the National Weather Service, the Fort Bend Office of Emergency Management, and the Pecan Grove MUD can predict at this time; it can change as weather conditions change. The Board is monitoring the situation and has instructed Jones & Carter and EDP to update the website accordingly. We are working with closely with EDP during this event. Please refer back to the website for additional information as we can post it.  Please keep in mind our first priority is taking care of the system for the flood protection of the District’s residents.

WCA Collection Cancelled for Monday

To all WCA Houston Area Customers and Employees,

Due to severe weather and flooding conditions in the greater Houston area, which are expected to continue throughout today and possibly longer, WCA will not be servicing waste collection pick-ups that are scheduled for today (Monday). Subject to further notice due to continued severe weather developments, Monday scheduled pick-ups for residential customers will be serviced on Thursday (April 21st). We regret any inconvenience caused by this event.

We will determine whether we can safely provide collection services to WCA customers who are scheduled for Tuesday pick-up once we have a better picture of weather and road conditions for tomorrow. Another announcement regarding Tuesday service will be made at the earliest opportunity.

UPDATE: District Emergency Preparedness In Action

UPDATED:  Monday April 18 at 8:28 AM

Click here to sign up to receive email alerts regarding district updates

The District’s Operator, EDP, started emergency operations this at about 4:00 a.m. this morning, Monday, April 18. The District has received several calls from customers about street flooding. EDP is patrolling the neighborhood to remove debris in storm sewers in addition to other emergency preparedness measures. Oyster Creek is high; therefore, the District activated the north storm water pump station. We have several lift stations with high levels and high flow rates from storm water infiltration.

We are addressing the situation and monitoring flows. The EDP call center will be emergency operation until it is safe for our neighborhood. Currently we have 7 field personnel out in the District working on emergency preparedness. The South pump station is ready for operation should it need to be turned on. Stay tuned for additional information as we have it. Keep in mind, our first priority is safety not posting information to the website, but we will post updates as we can to help inform the public throughout the day.

Remembering Safety in Our Community

Another school year is already kicking off! In the midst of back-to-school and holidays fast approaching, it is important to remember how to make your family and our community as safe as possible. Here are some helpful tips from the Fort Bend County Sheriff’s Office:

  • Remember to be sure to remove your valuables from your vehicle and lock the doors. Valuables sitting in a car, visible through a window make your car an easy target. And because criminals are looking for the easiest and fastest route into your car, a locked door is a simple and effective deterrent.
  • Be sure to close your garage door. This not only secures what is stored in your garage but also seals off access to your home. Turn the porch light on to illuminate your driveway….
