Salmon Resource - Sensitive Area Mapping
About SR-SAM
About SR-SAM

The primary purpose of the Salmon Resources and Sensitive Area Mapping (SR-SAM) project is to provide accurate resource protection mapping that enables roadway maintenance crews to perform their required activities (e.g., mowing, pesticide applications, etc.) with minimized disturbance to sensitive areas and their threatened and endangered resources.



In an effort to minimize impacts to natural resources adjacent to state highways, ODOT has worked with several state and federal agencies to develop a Routine Road Maintenance Guide that describes Best Management Practices for roadside water quality and habitat conservation.

ODOT´s maintenance activities can be divided into six areas:
  • Surfacing and Shoulder Work
  • Drainage Work
  • Vegetation Control
  • Bridge Work
  • Snow and Ice Removal
  • Guardrail and Grindout
