Streambank Stabilization

 

In 2023 and 2024, JRA hosted a series of diverse learning opportunities for Consortium partners to build capacity for streambank stabilization in the Upper and Middle James River watersheds.

The Streambank Stabilization Learning Journey generated diverse resources. Have a question about a resource for implementation or use? Staff contacts are listed under each resource. Learn more on the Journey post »

What is Streambank Stabilization?

Stream systems are complex landforms that have developed over the course of Earth’s history, and these systems are essential habitat for many organisms. Current and historic watershed conditions, and rapid anthropogenic impacts have altered the stream ecosystems in the Upper and Middle James River watersheds.

Streambank stabilization consists of vegetative, structural and bioengineering methods to stabilize and protect streambanks. These interventions to restore streambank stability require a robust understanding of stream systems, their evolution, and the watershed areas that contribute to them.

PHASE 1: Know Your Stream Basics

Streambank stabilization is a restoration approach that may be used to slow severe erosion and channel migration, though it is important to carefully consider the benefits and impacts on a site-by-site basis. Stabilization can include increased planting and on a larger scale, structure installation.

PHASE 2: Site Selection

A restoration project team will need to determine the objectives of the potential project, the local and watershed-level constraints, possible conflicts with infrastructure or land use, the agenda and desires of the landowner(s), and any implications the project may have downstream before determining which restoration approach to take.

During site visits, it is important to take detailed notes of site conditions and consider potential tradeoffs to help teams determine if streambank stabilization is the right intervention.

PHASE 3: Design & Permitting

Additional data from site level surveys will be needed to support the design and permitting process. When developing your design(s), consider both your objectives and any constraints (legal, physical, environmental, and regulatory) present.

Streambank stabilization and restoration projects typically require local land disturbance permits similar to those required for other landscape altering projects. Localities may have different thresholds to determine when permits are applicable, but generally projects including land disturbance, clearing, and/or planting require local permitting. Your local Army Corps of Engineers field office can help. You can find a chart of typical permits below.
