As part of the preparation of an Environmental Assessment for the El Portal Road Reconstruction, a variety of non-destructive data collection activities, including wildlife surveys, wetland and vegetation surveys, transportation studies, geologic and hydrologic analysis, analysis of historic properties and cultural landscape features, and other non-destructive research activities will be needed. All of the activities proposed in this project would be conducted by staff or contractors in the El Portal Road Reconstruction project area. Data will be collected by observation, transit, GIS, etc., and no activity would create ground disturbance or disturbance to vegetation or wildlife in excess of that created by a person walking and observing in the project area.
