Forensic Evaluation; Repair Design
Line and Grade
Line and Grade developed a unique way to determine the required repairs to a vintage stormwater basin in Albemarle County. The basin was overgrown and non functioning. Line and Grade developed a forensic evaluation strategy which was used to identify the cause of failure as well as inform future repair considerations. Given the graphic images on this page, it can be seen that over a period of nearly 30 years a large deposit of soils migrated from upstream of the basin and settled at the basin’s lowest point. Understanding this sediment deposit location allowed the repair strategy to be very specific and isolated. Thus saving the client money and allowing the contract documents to be very precise with regard to the work area.
