Drainage structures help to shed water off of our trails, which reduces erosion and increases sustainability. There are several different types of drainage structures such as dips, knicks, swales, and waterbars.
In this workshop you will learn how drainage problems can develop on sections of trail and how to mitigate them with drainage construction and maintenance. Skills taught will include assessing trail problems, drain construction, and drain maintenance.
