Erosion and Sediment Control Calculation and Process Review – 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
