PWA's Watershed Division is nationally recognized for its innovative work in sediment source assessment, watershed restoration, and erosion control plans for upland salmonid habitat protection. Projects range from simple site investigations and erosion control projects, to large-scale watershed assessments and sediment source investigations, to highly complex restoration and sediment control efforts. Professional experience for the firm’s owners and principals includes planning, organizing, implementing, and monitoring the internationally renown, $50 million watershed rehabilitation program at Redwood National Park in northern California. An integral part of this watershed rehabilitation and management program included the on-site field review of hundreds of private and industrial timber harvesting plans and proposed land use plans within the Redwood Creek watershed.
