Water Resources & Shoreline Design


Red Barn knows the regulations and permitting requirements to manage, design, model, and provide coordination with critical area specialists. Our staff understands that there are special regulations that are in place to protect the environment and for future watershed/fish passage improvement projects. We coordinate with agencies, Owners, design team, and Tribes to ensure our solution meets the intent of the current regulations.

  • Stream alignment & cross-sections (using UAV/Drone & Survey Mapping)
  • Wetland Delineation (using Survey Mapping to survey flags)
  • Soil conditions & analysis (using Geotechnical Services)
  • Setbacks and site layout for utilities & residential projects
