Time-Critical Disaster Response, Flood Control Repairs

Hawaii

In response to a disaster declaration and request for federal assistance, CAPE provided time-critical infrastructure repairs to an existing flood control project located along a river on Maui. Historic rains caused extremely high channel velocities, and significant debris flows damaged federal levees, causing erosion, scour, and slope failures. Critical infrastructure and hazards to life and safety were of concern if the levee system had failed. Before starting the work, about a dozen local residents and Native Hawaiian cultural practitioners blessed the river and our workers. After receiving that honor, CAPE safely implemented stormwater management controls, embankment stabilization, and levee repairs, including stream diversion away from the repair area, dewatering, and installation of erosion and sediment controls. We completed stream restoration, restoring seven eroded river sections to pre-flood conditions. Despite challenges faced during the rainy season and fluctuating river stages, CAPE was able to complete this time-critical levee repair project on schedule and under budget.
