Borough of Perkasie Stream Restoration
F. X. Browne, Inc. designed a bioengineering stabilization project to address severe erosion problems along 700 linear feet of an island within the East Branch Perkiomen Creek. The island is a valuable historical, natural, and cultural resource for the Borough of Perkasie. The design consisted of grading one side of the island, while extending the other side of the island using a vegetated geogrid technique. Using this approach, the amount of usable space on the island was maintained, and the majority of large trees on the island were preserved. A customized native seeding mix and shrub planting plan were developed to provide both excellent erosion control and improved aesthetics.
F. X. Browne, Inc. used HEC-RAS modeling to determine shear stress and velocities for the design discharge.
