Erosion and Sediment Control Calculation and Process Review – Confidential Client – Eastern U.S.

This large roadway construction project was experiencing overflow events from temporary construction storm water basins. This resulted in sediment from the basins entering adjacent waterways.  Since the project was in its initial stages and additional basins were planned, the client was concerned that the basins were undersized. The client had compiled calculations and reviewed the methodology for sizing of the sediment basins.  STONE was contracted to peer review this report, independently perform calculations, review processes and applicability of equations used, evaluate the validity of the argument that the basins were undersized, and provide a detailed report.

STONE reviewed hundreds of pages of plans, numerous sources of regulatory guidance, and assessed the validity of equations and parameters used within a fast-track four week time-frame

“STONE performed the ecological survey, environmental sites assessment, wetland delineation, waterway permit for 20 culverts throughout Monroe and Washington Counties. They also prepared the environmental document. We got praises from Ohio Department of Transportation (ODOT) Office of Environmental Services (OES) about their performance. They were a pleasure to work with and were always very responsive.”
