Erosion Control
Erosion Control Handbook for Local Roads
Minnesota Local Road Research Board, Minnesota Dept. of Transportation, Federal Highway Administration, Minnesota LTAP, 2003 (Download PDF (2.5 MB))
Gives guidelines and methods for effective erosion control on low-volume roads. It illustrates these methods with case studies outlining best management practices, and tells you how to deal with local watershed districts and other agencies. In addition, it provides detailed information to guide you through both Phase I and Phase II of the National Pollutant Discharge Elimination System (NPDES) permit process.
Mn/DOT Erosion Control Handbook (2002)
Not available online.
Available from the Mn/DOT
Office of Environmental Services
Offers useful information for planning erosion and sediment control measures on a construction project and for working with Mn/DOT and governing agencies.
Characteristics of Erosion Control Measures and Their Impact on Erosion

Erosion control blankets are a popular tool for minimizing erosion due to stormwater runoff on road construction projects, but how effective are the various types of blankets on the long slopes typical of roadside areas? With funding from Mn/DOT, U of M Professor Bruce Wilson of the Department of Biosystems and Agricultural Engineering set out to answer that question with a field study under artificial rainfall conditions.
This project endeavored to expand experimental data on erosion control blankets and develop greater understanding of how blankets and erosion principles interact. Blankets that are effective in reducing raindrop impact may become ineffective in controlling soil detachment and runoff (rill erosion) on longer slopes. This field study of erosion control products under artificial rainfall conditions was conducted at the Highway 10 overpass in Coon Rapids, Minnesota. Examining long slope lengths (60 feet and 100 feet), bare soil erosion was compared to erosion under straw blankets, wood fiber blankets, straw mulch, and sprayed emulsion. Measurements of runoff, erosion, and biomass (vegetative growth) were made in spring and fall under wet and dry conditions. Sediment loads for bare soil were 8 times larger than other treatments. Sediment loads were substantially smaller for the fall runs than the spring runs, largely due to the substantially increased vegetative cover (biomass).
