Construction Site Runoff Control
CONSTRUCTION SITE RUNOFF CONTROL
According to the EPA Fact sheet on Construction Site Runoff Control, “Sediment runoff rates from construction sites are typically ten to twenty times greater than those of agricultural lands, and one thousand to two thousand times greater than those of forest lands. During a short period of time, construction sites can contribute more sediment to streams than can be deposited naturally during several decades. The resulting situation, and the contribution of other pollutants from construction sites, can cause physical, chemical, and biological harm to our nation’s waters.”

U of M construction standards require temporary and permanent erosion and sediment control measures be incorporated into the design. The construction documents must identify specific controls and locations as well as contractor implementation and inspection responsibilities. Additionally, any storm water discharge from a construction site must be visibly free of sediment.
Sediment can be controlled through the use of silt fences, biologs, sediment traps, check dams, and sandbag barriers. Erosion can be prevented using existing vegetation, mulch, sod, and geotextiles. In addition, sites should be kept free of loose trash and debris.
Construction projects within an urbanized area boundary disturbing more than 3,000 sq ft of land area are requited to have a grading permit through the University of Minnesota Building Code Office. These projects have to meet the storm water requirements spelled out in the University of Minnesota Construction Standards and Specifications in order to obtain that permit. Additional information for design professionals can be found on the Design and Construction Assistance portion of our website.
