Project Scope

The new pump station under construction for the City of Dallas Water required retaining walls at the water intake structure submerged deep within the water of Lake Fork. Pinnacle Design/Build provided a MSE retaining wall as a value engineering alternative to cast in place walls. The design utilized the Redi-Rock 41” deep facing unit to withstand the lake’s wave action. At the tallest point, the wall stands 33 ft. tall and is mostly submerged. The total project contains 6,000 square feet of Redi-Rock blocks. The engineered solution provided structural stability and aesthetic appeal.
