Wilelinor Stream Valley Restoration

The Wilelinor Stream Valley restoration project is located just south of Annapolis in the community of Wilelinor Estates.  This headwater reach of Church Creek, restored in 2004, extends from the culvert under Rt. 2 to where it meets the tidal portion of Church creek. Church Creek is one of Anne Arundel County's most developed (impervious) subwatersheds.   150 years of urban development has led to increased sedimentation and higher than normal stormwater velocities through the area.

Two in-stream aquatic beds were created to capture sediment using sand seepage stream and wetland restoration techniques.   The project aimed to reestablish a stable stream profile that could handle the high velocity stormwater discharges, as well as provide high quality wetland and stream habitat during lower flows.  By slowing the flow of the water and trapping sediment, this project is able to enhance water quality, aquatic habitat, and ecological function.  The goal of this larger restoration effort is to take the necessary steps to repair the other tributaries to Church Creek, using similar restoration methods where appropriate, to create a model sub-watershed restoration.

This project was designed by Keith Underwood & Associates, constructed by Baltimore Pile Driving Co., and funded by Anne Arundel County and the Maryland State Highway Administration.  Since the installation in 2004, the Federation has continued to monitor and manage the site including invasive plant removal with volunteers.

Wilelinor Outfall Restoration

In 2014, the Federation completed a second project in the community of Wilelinor.  This project stabilized the eroding slope east of Wilelinor Drive.  Over the years, a 24 inch corrugated metal pipe installed as a culvert under Wilelinor Dr. had rotted at the bottom, as is often the case. The failed pipe had resulted in underground erosion and sinkholes.  The Federation, through project contractor Underwood & Associates, stabilized the eroding slope by compacting loose soils and installing a weir and cascades to reduce erosive energies. Native plants were planted throughout the site by the Maryland Conservation Corps, a long time Federation partner.
