Shoreline, riparian zone, dock and stabilization

Check regulated area and authorizations before dock, riprap, wall, deck, vegetation or machinery work near water.

VERT / GREEN

Locate shoreline/littoral/flood zone and contact the municipality before detailed design.

JAUNE / YELLOW

Even an accessory structure or vegetation work can have special rules.

ROUGE / RED

Major stabilization, fill, wall, machinery in littoral or unpermitted work: stop and obtain authorization/expertise.

Interactive triage

This triage helps choose the next step; it does not replace design, permitting or professional diagnosis.

Dock/boathouse
Verify type, dimensions, siting and permit before purchase/construction. Active shoreline erosion
Diagnose cause and compliant options for the aquatic environment. Wall/riprap proposed
Do not assume it is allowed; confirm authorization regime. Vegetation maintenance only
Still verify local restrictions before major cutting.
