Title:Chapter 7.3.2 BMP Considerations for Roadways.pdf
Summary:363-0300-002
Expiration Date:
Abstract:
  • Roadway runoff should not be discharged directly to infiltration systems without first reducing sediment loads.
  • Infiltration BMPs are appropriate for roadway systems but must be designed in conjunction with a measure (structural or non-structural) that reduces the amount of sediment in roadway runoff prior to infiltration.
  • Proximity to water supply sources should also be considered when designing infiltration BMPs, and the potential for groundwater chloride levels to be impacted by roadway runoff should be considered.
  • • Where practical, discharge storm sewers into wetland areas or vegetated swales instead of discharging directly to streams for filtering and temperature considerations.
