Limitations of the Infiltration Approach to Stormwater Management in the Highway Environment

The objective of this research is to develop guidance for state departments of transportation (DOTs) to determine appropriate siting of stormwater infiltration BMPs based on the limitations, risks, and benefits in the context of the built and natural environments (e.g., surface water and groundwater, soils, existing infrastructure). The guidance should address a broad range of issues and needs associated with choosing and siting infiltration BMPs for mitigating roadway stormwater that may include but not be limited to the following: (1) Limitations (e.g., cost, maintenance, regulatory, receiving waters, geotechnical) (2) Effects of climate, soils, topography, geology, vegetation, and land use (3) Effects of pollutants of concern on surface water and groundwater quality (4) Effects on surface water and groundwater quantity (e.g., recharge, baseflow augmentation, groundwater mounding) (5) Identification of gaps in the body of knowledge (6) Options for improving the effectiveness and reducing risks The guidance should outline decision-making processes and criteria that would assist agencies in identifying flexible solutions.
