Strawberry Run Stream Restoration
The Strawberry Run stream corridor is highly disturbed with severe erosion in various locations along the stream, including exhibiting evidence of downcutting with abandoned meanders approximately 3 feet higher than the current stream bed. In addition, significant amounts of broken concrete were observed in the channel, where it approaches and runs roughly parallel to Taft Avenue. Restoration is necessary to reestablish a stable pattern and profile in the stream. Restoring this portion of the stream will create a cohesive restored ecosystem corridor. This restoration will help prevent pollution (sediment and phosphorous) associated with erosion from being delivered downstream.
The Virginia Department of Environmental Quality (VDEQ) awarded the City a competitive $800,000 Stormwater Local Assistance Fund (SLAF) grant for partial funding of this project. Currently, the total estimated project cost is $1.6 million. The SLAF grant program was initiated by the Commonwealth of Virginia to provide financial support to municipalities implementing projects to reduce stormwater pollution as the new Chesapeake Bay TMDL requirements were being passed down through the MS4 permits.
Impact on Trees
In total 353 trees were surveyed around the project site and, of those, 36 of them are considered to be 'notable' trees, as defined by Recreation, Parks & Cultural Activities (RPCA), Natural Resources. The project designers worked with RPCA and adjusted the stream alignment to reduce the total amount of trees removed from the original plan of 206 down to 89. This adjustment also lead to a decrease in removal of 'notable' trees with 13 slated for removal, down from 34. Of note, these 13 'notable' trees to be removed are impacted by stream erosion and are currently at risk for negative health impacts. The project currently consists of replanting 1,030 native tree species (3-gallon container). The planting mix also includes 350 shrubs (1-gallon container) including American Elderberry, Buttonbush, and Spicebush; 5,100 "live stakes" (3-4 foot) of Silky Dogwood, Smooth Alder, and Black Willow; and 548 2-inch plugs of rushes and sedges.
The City welcomes all feedback concerning stream restorations and ways to reduce water pollution and achieve the Chesapeake Bay goals. All comments received through January 30, 2021, will be reviewed and answered by the Strawberry Run Stream Restoration Team which includes several City departments (TES, DPI, and RPCA) and Consultants. Comments and responses will be made available on this webpage. Based on community feedback, the City works with the Consultants to adjust project plans accordingly.
There continues to be public community meetings to provide general information about the project. Meeting information is included below.
