The Mill Creek Drainage Relief Tunnel is a construction project that will bring needed infrastructure improvement to east Dallas, Texas. Stiver Engineering provided construction consulting services for the contractor prior to and during the tunnel construction.

The tunnel, which stretches from the State-Thomas District in Uptown Dallas, through Mill Creek and Peaks Branch, will be constructed mostly underground with little impact to neighborhoods. Once complete, the approximately five mile-long tunnel will sit 70 to 100 feet below ground to provide flood relief.

The Mill Creek Drainage Relief Tunnel is a five-mile underground tunnel that will provide 100-year flood protection for nearly 6,000 commercial and residential properties in the east Dallas area, including Baylor Medical Center. The current drainage system in these areas was constructed 50 to 70 years ago, and only provides a two to five year flood protection. Major flooding that occurred in 1995, 2003, 2006 and 2009 crippled these areas and showed dire need for the construction of this drainage relief tunnel. The Mill Creek/Peaks Branch/State-Thomas Drainage Relief Tunnel will improve stormwater management resulting in saved lives, protection of schools, medical facilities, residents and streets. Construction began in spring 2018 and is slated for completion in 2023. The tunnel is being constructed by Southland Mole Joint Venture. Prior to construction beginning, a tunnel-boring machine (TBM) will be constructed on site. By using a TBM, there will be minimal utility relocation, as well as minimal street and traffic impacts. Once complete, the tunnel will be approximately 30 feet in diameter, and will be designed to carry a maximum flow of nine million gallons per minute. This provides exponential relief of flooding during large rain events. The tunnel will have six intake sites along the alignment. These include:

  • Woodall Rodgers Intake – Intersection of Woodall Rodgers Freeway and Maple-Routh Connection
  • Mill Creek Intake – Intersection of San Jacinto Street and Apple Street
  • Peaks Branch Intake – Intersection of North Carroll Avenue and Victor Street
  • Peaks Branch 2 Intake – Intersection of E R L Thornton Freeway (I-30) and South Hill Avenue
  • East Peaks Branch Intake – Intersection of Bank Street and Herndon Drive
  • Outfall – White Rock Creek at Barber Avenue

 

Emmons Motor Co. is a Houston area automotive dealership that has been operating in Houston, Texas since 1972.  The used car dealership relocated to 16 acres at Interstate 45 and Farm to Market Road 528 in the Clear Lake area.  The total cost of the project is estimated at $15 million and was completed in November 2017.

The new 48,000-square-foot dealership holds roughly 450 cars on-site, up from Emmons’ previous Pasadena location that handled 350 cars. The new dealership also includes a state-of-the-art body shop, a waiting area and an 18,000-square-foot showroom.

Stiver Engineering provided the civil engineering site development services for the Emmons Project.

The Bergamos Spa Retreat is a $6.5 million, 22,000-square-foot day spa and is the largest freestanding day spa in Texas.  It is owned by Marylyn Reed, the great-granddaughter of the late beauty and skincare mogul Mary Kay Ash.  The spa was completely renovated after the facility was destroyed by Hurricane Harvey in 2017.

Stiver Engineering provided the site civil engineering design for the redevelopment of the site after Hurricane damaged the old facilities in 2017.

 

The largest of the Lower Colorado River Authority’s (LCRA) new water supply projects is an off-channel reservoir that is being constructed near the Texas Gulf Coast. The project will be the first significant new water supply reservoir developed in the lower Colorado River basin in decades. The Lane City Reservoir will be constructed off the main channel of the Colorado River, near Lane City in Wharton County.  The reservoir will add up to 90,000 acre-feet of firm water to the region’s supply.  Firm water is water that can be counted on without shortage even during a repeat of the worst drought conditions in the region’s history.  The Highland Lakes were created to manage floods on the Colorado River and to provide a sustainable source of water for the basin as a whole. The Lane City Reservoir is the first project that will allow LCRA to capture and store significant amounts of water downstream of the Highland Lakes.  The new reservoir will benefit the entire basin by helping reduce the amount of water otherwise required to be released from the Highland Lakes.

Stiver Engineering was retained by the contractor to provide construction consulting through excavation plans for the reservoir inlet/outlet structure, a permanent sheet pile shoring system in the Colorado River around the vertical intake pumps, miscellaneous structural design, excavation consulting  and dewatering consulting.

Stiver Engineering provided one of our clients located in Liberty County, Texas, with construction consulting through designs for a reinforced concrete stormwater pump station. The designs included two 60-inch diesel-powered pumps, a steel trash rack, and a reinforced concrete influent channel. We also provided rehabilitation designs for the adjacent original 1962 pump station, and we installed two new pumps. Stiver Engineering provided mechanical and structural plans to the contractor for construction.
