Construction Project Updates

Report From Justin Ring, Odyssey Engineering Group

PROJECTS UNDER CONSTRUCTION

Bullhead Slough Rehabilitation

The District is dredging silt out of Bullhead Slough and rehabilitating the side slopes which have eroded over time. Project includes installing ShoreSox product at the water’s edge to stabilize and prevent future erosion. Project includes eastern and middle sections of Bullhead. Rehabilitation of the western section of Bullhead will be performed in the future.

Contractor is complete with shore stabilization portion of the project and is approximately 50% complete with dredging operations.

Residents are reminded that this will be an active heavy construction site. DO NOT enter construction site at any time. Unauthorized access to the construction area places the unauthorized visitor and construction crews at risk.

Jones Creek Slope Rehabilitation

Construction is complete! The District wishes to thank the residents of Pecan Lakes for their understanding and patience during the construction of this project. The Contractor, Texas Wall & Landscape, did a great job in meeting the project goals and the project timeline.

Improvements to Raw Water Tanks at Surface Water Treatment Plant

The District is installing a floating mixer in each of the raw water storage tanks at the Surface Water Treatment Plant located off Skinner Road. The mixers create constant movement in the raw water to limit sediment from settling to the bottom of the tank. In addition, stairs and walkways are being installed as part of this project to improve operator access to the tanks.

Project is under construction. Sediment in the west tank will be removed in August and catwalk assembly will begin once that is complete.

South Pump Station Automation

The District is updating the electrical system to allow for the pumps at the south pump station to automatically turn on or off based on the water level in the main channel.

Project is complete.

Electrical Improvements and Generator at Water Plant No. 2

The District is updating the electrical system including installation of a new generator at water plant no. 2 (located near the elevated storage tank).

Construction has commenced; therefore, Water Plant No. 2 is currently non-operational due to construction activity. Due to improvements from Centerpoint that are required for the project, the plant is expected to placed back into service in later September/early October.

Improvements at Water Plant No. 3

The District is modifying the pumps and piping system at water plant no. 3 (located at the end of Willow Bend Dr.).

Notice to Proceed has been issued. Contractor is ordering the necessary components and construction is expected to begin once Water Plant No. 2 is back online.

North Pump Station Improvements

The District is improving the access to the north pump station by adjusting the headwall and grading modifications. Project also includes automation of the pumps based on level of water in Bullhead Slough.

Construction activity onsite has commenced. The contractor has completed the headwall that will improve operational access to the pump station and is currently grading the site.

Bullhead Slough Rehabilitation

Scope of Work

Bullhead Slough (“Slough”) is a manmade channel that serves as an inline detention/amenity basin. The slough consists of three segments. All three segments are bounded on the north and south by Victoria Gardens Drive and Old Dixie Drive, respectively. The first segment, Eastern Pond 3, begins at Colonel Court Drive and ends at Old South Road. The second segment, Middle Pond 2, begins at Old South Road and ends at Farmer Road. The third segment, Western Pond 1, begins at Farmer Road and ends at the outfall into Oyster Creek. This project includes the first and second segments, or Eastern Pond 3 and Middle Pond 2. The third segment, Western Pond 1, will be rehabilitated under a different project in the future.

Existing Conditions

Over time the Slough’s side slopes have eroded. The diminished side slopes reduce the slope’s stability and can lead to worsening slope failures. Additionally, silt, or very fine dirt, has been deposited along the entirety of the Slough as a result of slope erosion and run-off. Silt has built up and reduced the depth of the Slough and created islands of vegetation growth. The shallower water leads to mosquitos, algae, and vegetation as well as reduces detention volume. Finally, the build-up of silt disrupts the fountains within the Slough.

Proposed Conditions

This project will resolve both of the existing condition issues of failed side slopes and silt build-up by removing the silt by dredging and restoring the side slopes with ShoreSOX installation. The dredged material is pumped into a dewatering bag to dry and then is hauled off-site and legally deposited. ShoreSOX re-stabilize shorelines using an open-ended containment system that is filled with locally sourced organic material. The ShoreSOX are then seeded to allow vegetation to grow through the sock and halt soil erosion.

Schedule

The Notice to Proceed will be issued on July 6, 2020 and the project is expected to be completed in November 2020.

Procedure

The Contractor, Storm Water Solutions, will begin by prepping the ShoreSOX along the edges of the most eroded side slopes. They will stage the primary dewatering bags on the northeast side of the Eastern Pond 3. They will also stage auxiliary/backup dewatering bags near the southwest side of Western Pond 1. The Contractor will then use a crane to place the hydraulic dredge into Eastern Pond 3. The dredge will remove silt via pumping into the dewatering bags. The dewatering bags will be surrounded by haybales as stormwater pollution prevention and to prevent any silt from reentering the slough. The dewatered material will be tested for acceptability for filling the ShoreSOX in lieu of imported soil/mulch. If unsuitable, the dewatered materials will be loaded into trailers and hauled off-site for legal disposal. This process will be repeated for Middle Pond 2.

The Contractor is allowed to work from 7 a.m. until sunset for seven days a week. At this time, the Contractor does not expect to work seven days a week in order to achieve the project delivery schedule. Weekend schedules will be approved on an as needed basis.

Residents are reminded that this is an active construction site. DO NOT enter construction site at any time.

Construction Notification

Dear Pecan Grove Resident,

As part of our ongoing efforts to maintain the levee facilities in the community, Pecan Grove Municipal Utility District has awarded the contract for the Jones Creek Rehabilitation project to Texas Wall & Landscape (TWL). This project will repair the slope failures along Jones Creek behind the Pecan Lakes subdivision that were caused by Hurricane Harvey. The construction project involves removing the existing sheet piling and constructing a soldier pile wall with gabion basket slope protection. The gabion basket system is the preferred system for slope stabilization by the U.S. Army Corps of Engineers due to their flexibility during the life of the project as well as their ability to allow saturated soils to more freely drain without impacting the structural stability of the overall system. The gabion system has successfully been used in similar areas along the Brazos River and Jones Creek. Please visit the Districts’ website for more information.

TWL will begin construction as early as the first week of October 2019. The construction project is expected to take 220 days, depending on weather and the conditions of the Brazos River. Due to the expedited construction schedule, TWL will be working seven (7) days a week from 7 a.m. until sunset. We are receiving federal funding for a significant portion of the design and construction and expedited construction is necessary to meet the federal funding requirements. We apologize in advance for the fact that the construction will be loud at times.

TWL will access the site from the north via F.M. 359 and from the east via a haul road from FM359, just north of the Pecan Grove Baptist Church. Please be mindful of the construction traffic in these areas.

During this time please remember this is a construction site and stay safe! Please keep out of the construction area and instruct children not to play in or around the construction site.

If you have any questions about the work, please contact the District office at 281-238-5000.
