Presenter Bio:

A team of presenters will be walking you through the project initiation, design and construction of this restoration. Presenters will include the Karen Jennings of Anne Arundel County, the funding agency, Brett Schrey and Rich Pfingsten of Stantec, the design firm, and Adam Nabors of EQR, the contractor. 

Project Description:

This renovation included the restoration of an eroding stream channel network (approximately 6,200 linear feet) on the golf course property, removing culvert crossings and changing to boardwalk crossings to allow better floodplain connectivity. The goal was to restore a fully integrated floodplain wetland system which was incorporated into the golf course landscape. Additional aspects of stream design included developing mini regional curves from onsite surveyed reference reaches and daylighting existing piped stream sections to natural channel design. 

Along with stabilizing eroding channels, floodplain reconnection was a key goal of the design. In the past, functioning floodplains and conncted wetlands have been overlooked when developing stream restoration goals. Stantec uses the term “valley restoration” to describe design techniques which include installing a small baseflow sized channel and enhancing the floodplain with features such as vernal pools, large woody debris, and back eddy channels. Flows that access the floodplain frequently serve to contribute to micro-habitat in these areas which creates significant diversity within the plant and animal community. Sediment and nutrients deposited in the floodplain are prevented from downstream mobilization, enable nutrient processing, and serve to aid in the restoration of sensitive waterbodies such as the Chesapeake Bay. 

Several of the existing entrenched headwater stream channels were designed and constructed using a “Stage 0” natural channel restoration approach, where the small baseflow stream channel, and well-connected floodplain and wetlands feature log valley grade controls, log vane riffles, log jams, and floodplain woody material placement to encourage splitting and braiding of flows during storm events. This technique is being used frequently on Coastal Plain streams to promote sediment and nutrient load reductions, while creating improved habitat and biological uplift. Steeper channel reaches were designed with similar woody features in areas where the floodplain was wide, and boulder valley grade controls and boulder jams in narrower reaches to provide flow diversity.
