The wetlands mitigation project was a means to restore 14 acres of land intended to be reclaimed as wetlands during the construction of the 90-acre Chambers Lake in Hibernia Park, Chester County. The wetlands mitigation will create the first phase of an eventual water trailhead on the popular section of the West Branch of the Brandywine Creek.
Two wetland areas were constructed on the site. The construction of the first area required excavation of approximately 2,000 cubic yards of soil. The excavated soil was used to construct an earthen berm for the second wetland area that was construction on grade. Berner installed 1,400 linear feet of a compacted core trench and a compacted earthen berm that ranged from a few inches to five feet above grade.
