Drainage Design

Rain Doesn’t Have to Ruin Your Day

When storms happen, we know that driving conditions can quickly become stressors. RTG’s goal is to develop a drainage design that provides the safest driving conditions for the traveling public, considers the long-term durability and maintenance of the roadway, and anticipates the impacts to adjacent property owners.  It is not enough to just address a problem, we must develop a solution that prevents it from re-occurring. 

Potential impacts to adjacent property owners can often lead to drainage design driving the overall project design. Our engineers have successfully completed multiple projects across the state by collaborating with roadway and bridge designers to reduce impacts while providing cost-effective designs. 

We conduct site visits to collect data and see firsthand the watershed conditions for the existing infrastructure. We then perform a hydrologic analysis, including a pre-project and post-project calculation to determine the effects of the project, a hydraulic analysis to calculate water surface elevations for use in developing the sizing and layout options for bridges, culverts, and inlets, and an impact analysis to evaluate impacts to adjacent properties. 

Drainage design practices vary dramatically from region to region in Texas but, from our experience working on projects across the state, we know that many times there are still “lessons learned” on a project in one region that can be beneficial to a different region. Our team is well-versed in providing practical, efficient solutions to local projects using our knowledge and understanding of various drainage conditions throughout Texas.
