Article Highlights Innovative Dam Design
Innovative improvements to Upper Brushy Creek Dam No. 7 were featured in a Community Impact news article this month after a public open house for the project. The dam is located in Williamson County, where flooding during Tropical Storm Hermine caused damage to many houses, parks and structures in 2010.
We worked with the Upper Brushy Creek WCID to develop Dam 7’s innovative labyrinth weir spillway design, which will pass required flood flows without having to raise the dam, a solution that wasn’t feasible due to its location. The team used renderings and a 3D-printed model to represent the planned design (pictured at right). The project includes hike-and-bike trail upgrades and aesthetic improvements and is currently at 90% design. Construction is anticipated to start in 2016, and we will provide construction phase services.
Our team served as the consulting engineer for the Upper Brushy Creek Water Control Improvement District since 1999, designing modernization improvements for 21 of 23 dams the district maintains and developing Emergency Action Plans. Dam 7 is the final dam to be modernized by the District and Freese and Nichols.
