Project Description:


David Moore Drive is one of the many roads that flood frequently in the “Flash Flood Alley” areas of Austin.  The goal of this project was to address flood waters from Slaughter Creek over-topping the roadway during 2-yr or greater storm events.  The upgrade for the low water crossing was designed to meet the City’s Drainage Criteria Manual, so the road would not flood in a 25-year storm, and there would be less than six inches of water over-topping it during a 100-year storm. The project provided drainage improvement alternatives to prevent flooding. The scope included the installation of a 30’-8’ Crown-Span Bridge intended to return the creek to its natural state, and two 10’ x 5’ box culverts on each side that will engage during larger storm events.

The improvements now allow a safe crossing over Slaughter Creek during storm conditions for emergency vehicles and the community at large, as well as providing direct access to the nearby school.
