Stormwater Runoff Research – ms consultants / Ohio Department of Transportation, Office of Research
Ohio Statewide Project

STONE is currently part of a team with ms consultants and the U.S. Geological Survey (USGS) to complete a stormwater research project. The intent of the research project is to evaluate post construction best management practices (BMP) alterations in order to obtain credit for stormwater volume reduction through infiltration and evapotranspiration. It is desired to develop plans using common Ohio Department of Transportation (ODOT) highway construction equipment, materials, and practices for installation of the vegetated filter strips. STONE’s role includes:

  • Meetings with ODOT and Ohio EPA
  • Development of Conceptual Amendment Plans
  • Assist with the identification of Research Sites
  • Amendment system Installation Observation
  • Research Evaluation and Input

As part of the first phase of the project, STONE prepared the “Soil Amendment Design Alternatives Summary and Final Recommendations” report. This report provided design for the soil amendment plans to be used in vegetated filter strips (VFS). VFS are generally located along roadways, in areas with gradual vegetated slopes, between the roadway shoulder and edge of the water conveyance (e.g. ditch). VFS generally reduce runoff through infiltration, storage, and evapotranspiration. Amended VFS (AVFS) have the ability to increase the amount of stormwater infiltration within the same area. Amendment materials researched included natural and manufactured materials. To manage costs and constructability, materials identified were readily-available in Ohio, materials that Ohio highway contractors typically deal with, and materials that were not cost prohibitive. Based on the goals of the project, the materials researched, discussions with the research team, and the desire for usable data to be analyzed following post construction monitoring, initially three amendment designs and two depths were reviewed. Following further research in input from ODOT and the team, final recommendations were made along with recommendations for construction installation practices.

“STONE is an instrumental part of our team on the Portsmouth By-Pass Project: the 16-mile new construction project, which is the single largest project in ODOT history. This project has come with more than its share of environmental challenges. STONE has delivered over 30 full environmental clearance reviews and reports we have requested as part of the project, handling them from start to finish in a very timely & cost effective manner. Furthermore, they’ve proven themselves as an extremely valuable resource when it comes to consulting on mitigation efforts, hazardous materials, and resolving various unknown environmental situations that the project has encountered.


From the top down STONE has proven they are committed to excellence and we look forward to working with them on many projects in the future.”
