Reclamation of the Summerlee site was completed in 1996 and involved refuse regrading, capping the refuse with clay topsoil and controlling surface drainage with concrete “fabri-form” channels. The reclamation succeeded in reducing surface water infiltration, but significantly changed the hydrology of the site. Soon after reclamation was completed, downstream property owners experienced increased flooding events. The Nolen’s live approximately 1,300 feet downstream of the Summerlee site, and a headwater tributary flows through their front yard. Increased water volume discharging from the Summerlee site has exceeded the capacity of underground culverts that run through the Nolen’s property. Consequently, this has resulted in their culverts becoming clogged and inoperable, which has created neighborhood wide flooding during heavy rain events. To provide long term solutions and water carrying capacity, an appropriately sized stream channel and culverts were designed to extend past the Nolen property and through two adjacent parcels; with the main goal of opening, restoring and connecting to the original tributary channel.
On August 30, 2012, PAN was awarded $180,957 by the West Virginia Department of Environmental Protection to implement a stream restoration project in the headwaters of the Wolf Creek Watershed. The stream restoration project restored a headwater tributary running through three adjoining parcels using natural stream design techniques (referred to as Nolen parcel, Amick parcel, Gilger parcel). PAN partnered with Baker Engineering to develop engineering plans and Ryan Environmental for implementation and construction of the restoration. The project involved restoring 600 ft. of stream back to an open channel, connecting the stream channel to appropriately sized culverts, and connecting the stream to the original tributary. The restoration project will reduce the frequency of flooding events, improve drainage through the adjoining parcels and restore stream functionality.
