BCE played a central role in advancing aquatic organism passage (AOP) across Kodiak Island, Alaska—an effort designed to reconnect critical fish habitats and bolster ecosystem resilience. As part of a multi-site infrastructure upgrade our team was contracted to develop design documents for eleven stream-crossing locations. Our design retrofitted aging culverts where natural waterways intersect roads and trails. The new design featured stream simulation channels constructed with culverts measuring up to 17 feet in diameter—carefully engineered to mirror natural flow and comply with USFWS’s stream simulation methodology. This ecological approach reduced disruption to aquatic life while reinforcing existing infrastructure against environmental stressors. Three comprehensive bid packages were completed, providing detailed construction documents, specifications, and cost estimates. The project exemplifies our commitment to sustainable engineering practices and habitat restoration—ensuring the longevity of Alaska’s natural waterways and the wildlife that depends on them.
