HOA’s approach us and ask great questions. Below is a retention basin. Basins are designed to fill with water during storms and discharge the water effectively. Debris and sediment often accumulate overtime causing problems. This image shows sediment thickness found by sediment probes & sonar technology. It’s vital to know how much sediment and other material accumulates in retention basins to insure that it is functioning properly.
This is a cool map of a recent post dredge map showing how far they are above and below grade! #bathymetry #dredging #hydrography #sedimentstudies #mappingnetwork
