Arroyo Seco Watershed Assessment
The Arroyo Seco Watershed Assessment (ASWA)is a comprehensive review of the state of the watershed and of projects to restore and enhance it. ASWA builds on the body of research, plans and reports that have been prepared in the last ten years
to chart the course for an Arroyo Seco Greenway that will provide for restoration and better management of our local watershed. The Draft Assessment has now been finalized.
The purpose of the assessment is to:
- Outline projects which address the needs of the Arroyo Seco Watershed identified in this and previous plans and documents.
- Provide a road map for future coordination and collaboration with the County of Los Angeles, the US Army Corps of Engineers and other agencies to implement Arroyo Seco Greenway projects by way of a governance structure—the Arroyo Seco Greenway Agreement.
- Provide a framework for future integration of transportation, energy, water resources, and restoration concerns in the development and rehabilitation of the Arroyo Seco Watershed.
The ASWA promotes and outlines key aspects of the Arroyo Seco Greenway, a series of integrated transportation, water resource and habitat enhancement projects along the 20 mile Arroyo Seco River corridor.
