Tusico Branch Stream Restoration, Phase 2

The second phase of the Tusico Branch stream restoration is slated to begin in June 2021. This project will restore 1,000 feet of stream between Keith Avenue and Springmann Drive. Restoration is anticipated to take six months to complete.

The Tusico Branch of Accotink Creek originates in Pat Rodio Park and flows east through residential neighborhoods. The first phase of the project was completed in 2020, restoring 900 feet of stream between Center Street and Chain Bridge Road.

Existing Conditions

Severe erosion is visible throughout this reach of stream and backyards are shrinking as private property washes downstream. Homeowners have installed rock walls and sandbags in an attempt to control erosion of their properties, but the stream banks remain unstable. Fast-flowing water during rain events continues to undercut roots, resulting in the loss of many trees.

Project Benefits

This project will stabilize the banks of the stream by regrading eroded banks and reinforcing existing rock walls. Cross-vanes will be installed to reduce flow velocity and create improved aquatic habitat. The project will also remove invasive bamboo where authorized by property owners and install native vegetation to slow the spread of bamboo in the future.

In addition to protecting private property, the project will improve water quality through the reduction of sediment, phosphorous, and nitrogen. The city earns credits toward the city’s Chesapeake Bay pollutant reduction requirements.

What to Expect

Residents can expect construction noise from heavy equipment, trucks, and chainsaws during work hours. The city’s noise ordinance allows construction activity between 7 a.m. and 6 p.m. on weekdays. There will be occasional construction traffic to the project entrance on Keith Ave, across from Pat Rodio Park.

Once the project is completed, properties along this reach of Tusico Branch will be protected from further erosion, water quality will be improved, and new trees and native vegetation will mature over time to create a healthy riparian buffer.

Funding

This project is supported by a combination of grant funding from Virginia DEQ’s Stormwater Local Assistance Fund and the city’s Storm Fund. The Storm Fund is a portion of the real estate tax rate dedicated to the city’s stormwater program.
