How will neighboring homes be protected during the dewatering process?
Through our 10 years of groundwater monitoring on the Parkside site, we have confirmed that shallow, perched groundwater exists at various levels throughout the upper 20 feet of the property. The levels are influenced by local conditions: The Wintersburg Channel, irrigation, rainfall percolation and seasonal fluctuations of the regional aquifer. These near-surface waters are not connected to the deeper regional aquifer, thus the term “perched.” The regional aquifer has been documented to fluctuate seasonally over a wide range, from as high as the ground surface to as much as 23 feet below. It is those past fluctuations that are of greatest significance when evaluating the potential for future settlement, or subsidence. Removing sub-surface water – dewatering – is a common practice that has been used in many development projects in the area, due to the area’s shallow and fluctuating groundwater levels and its abundance of highly compressible and liquefiable soils.
