What the buffer is
The Chesapeake Bay Preservation Act establishes Resource Protection Areas along tidal shorelines and tidal wetlands. These include a 100-foot vegetated buffer landward of the water that filters runoff and protects water quality. Disturbing land within the RPA through clearing, grading, or construction is regulated. Your Joint Permit Application must address CBPA requirements when your locality is covered.
How it affects docks and bulkheads
A pier or dock crossing the buffer to reach the water is expected and generally permissible. Land disturbance behind the shoreline, construction access paths, and especially shoreline stabilization choices all get more scrutiny. This is where the CBPA and Virginia’s living shoreline preference come together. Because hardening a shoreline with a bulkhead degrades the buffer’s ability to filter runoff, permit applications are increasingly asked to justify a hard structure over a living shoreline alternative.

What this means for your project
The CBPA rarely stops a reasonable dock or pier project, but it shapes the design and adds documentation to your JPA. A contractor who regularly permits in CBPA localities knows what reviewers look for and keeps this from becoming a delay.
