Drainage Design


What We Fix

A veteran District Engineer once proclaimed in a presentation that the four most important elements in a typical roadway project are drainage, drainage, drainage and drainage. Drainage changes and changes everything, during and after the project. Drainage is not predictable; it is dynamic. Other elements of a roadway project are static; they remain the same long after the project is completed.

This US 93 roadside channel met its match during construction, overwhelmed by a storm event. It was a race to remove sediment quickly and open up the channel to create more flow capacity.
