This permit covers a wide range of stabilization methods, including the placement of materials like riprap, bioengineering, and the construction of bulkheads or seawalls. It applies to both Section 10 navigable waters and Section 404 discharges of dredged or fill material .\n\nThe permit is specifically designed for activities that result in no more than minimal individual and cumulative adverse environmental effects. It emphasizes that the activity must be the minimum necessary to provide adequate stabilization and must be designed for long-term sustainability. The permit also authorizes temporary structures and fills necessary to complete the stabilization work.","Public feedback included support for the streamlined permitting process and concerns about the long-term impacts of bank hardening. Some commenters suggested that the 500-linear-foot threshold is too high, while others advocated for stronger requirements for bioengineering or 'living shorelines' .\n\nThe Corps responded that existing thresholds—which include cubic yard limits and the ability of district engineers to exercise discretionary authority—are appropriate for maintaining minimal impacts. They also noted that NWP 54 is specifically available for living shorelines, though NWP 13 remains a valid tool for traditional bank stabilization when properly designed.","Compliance managers, private property owners, and civil engineers use this permit to protect land and infrastructure from erosion.
