RES completed restoration of 86 acres of wetlands and 3,700 linear feet of stream as part of a watershed-scale headwater restoration project in Osceola Township, Tioga County, Pennsylvania. Construction was finalized in December 2022.

Restoration design was informed by site-specific geotechnical and hydrologic investigations that guided removal of drainage ditches, subsurface tiles, and legacy fill, as well as targeted grading adjustments to reestablish historic hydrology. In areas of soil compaction, RES implemented decompaction and constructed microtopographic variation to increase water retention and promote wetland reestablishment. Surface woody debris and brush were incorporated to enhance habitat complexity and carbon inputs, and all restored areas were planted with native wetland vegetation.

The project is currently in Year 4 of monitoring. Performance data continue to demonstrate progress toward long-term hydrologic function, vegetative establishment, and stream and wetland stability, reflecting a durable and sustainable restoration outcome.
