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

“STONE Environmental was a pleasure to work with. From the planning process to our onsite visit. They knew exactly what we wanted and were able to deliver in a timely fashion.  The on-site field engineer was very resourceful and her attention to the small details was phenomenal. I will be sure to use STONE on all my future environmental surveying projects.”
