Stormwater Management & Best Management Practices

Land-Use Specific BMPs


Stormwater Management on Agricultural Lands
Stormwater management on agricultural land focuses on both protecting water quality and reducing runoff volumes and rates.  Potential water quality concerns from agriculture include sediment, nutrients, bacteria, and pesticides.  Runoff quantity management aims to protect stream and groundwater quality, stability of streams, cropland, and infrastructure, and encourage groundwater recharge.    

Stormwater management on agricultural lands can be broken into two major categories, 1) Erosion and Sediment Control and 2) Manure and Nutrient Management.  Specific best management practices (BMPs) to consider under erosion and sediment include but are not limited to: Crop Field Soil Erosion and Sediment Control, Streamside Pasture Management, Management of Farm Lanes, Walkways, and Forest Lanes, Maintenance of Existing BMPs, and more.  Factors to consider that are associated with manure and nutrient management include Manure Storage, Heavy Use Areas Protection, Record Keeping, Surface and Roof Water Control, Well Head and Groundwater Protection, Maintenance of Existing BMPs, and more.

Ag BMP Spotlight: Riparian Buffers
Riparian buffers are non-structural BMPs that are extremely beneficial tools for stormwater management; agricultural land is often an ideal setting to preserve or restore riparian buffers.  Their many stormwater benefits include:

  • Filter pollutants,
  • Reduce peak rate,
  • Reduce runoff volume,
  • Stabilize banks,
  • Moderate in-stream temperature, and
  • Facilitate groundwater recharge.   

These land management practices have numerous benefits beyond stormwater management, including but not limited to the following:

  • Provide habitat for aquatic and terrestrial wildlife,
  • Moderate temperature,
  • Improve aesthetics, and
  • Improve air quality.
