Our client was dealing with water quality issue and received recommendation to increase the pond depth. After checking the local government regulations and originally approved plans our firm found that there were no
obsticles to dredge except for one major problem.
After completion of topographic and bathymetric surveys - we found out that due to seepage and underwater slope failures it was severely eroded. Further undermining by dredging without proper stabilization would cause sudden collapse of lake bank, creating dangerous situation for dredging contractor, people and vehicles in the immediate vicinity of shoreline.
