Unrolled Asphalt Berm Edge Clean Water Diversion

Here is another cool trick for keeping clean water out of your project. The contractor put down ATB (asphalt-treated base) and asphalt but didn’t roll (compact) the edge, which left a 3 or 4 inch berm. Clean rain water was kept on the asphalt rather than flowing off into the dirt shoulder and disturbed areas.

Clean Water Diversion Using an Unrolled Asphalt Road Edge

My favorite best management practices are the ones that involve a slight modification of the contractor’s “means and methods“. On this project, the foreman told the roller operator not to go all the way to the edge of the new asphalt, leaving a small, rolled asphalt edge. Since this is the first lift of asphalt, with several more inches to be added later, this will be covered up near the end of the project. At that time, stormwater will run off the asphalt shoulder into a grass-lined ditch. The best part is this was done at no additional cost to the owner.

Clean Water Diversion Using Jersey Barrier and Asphalt Berm

The more clean water you keep from flowing into your job site, the less dirty water you will have to manage. Placing a berm along the base of “Jersey Barrier” is one way to accomplish this. Materials you can use include cold patch, extruded asphalt curbing, or sand bags.

Construction Project Designed to Keep Clean Water Out

During project design, it is important to develop a storm water management basis for design. This is done primarily for the permanent storm water conveyance systems, but is is also important to do this for the temporary erosion controls which are, in effect, a temporary storm water conveyance system. This project, though covering a small area, drains directly to a creek which is tributary to an important salmon spawning river. In addition, there was some risk that the project might not be complete before the fall rains would begin. Because of these things, the basis of design process led to a system of clean water diversion and site water collection and dispersal into vegetation.
