Anacostia Riparian Meadow Restoration

Maryland
2025
Overview

In 2007 the Anacostia Watershed Society (AWS) initiated an experimental research project, called the 38th St. Bridge Project, on the rip-rap slope along the streambanks in order to demonstrate an a...

Methodology

Approach

This project implemented a comprehensive riparian buffer restoration restoration approach, combining scientific research with community engagement and traditional ecological knowledge.

Implementation Steps

  1. Baseline assessment and site selection
  2. Stakeholder consultation and community engagement
  3. Design and planning phase with technical experts
  4. Implementation with local workforce training
  5. Monitoring and adaptive management

Timeline

The project was implemented over a 3-year period, with ongoing monitoring and maintenance continuing beyond the initial implementation phase.
