How do we obtain environmental compliance?

graphic of process

The planning and design process for projects under the Yolo Bypass Habitat Restoration Program is outlined in the 2012 Yolo Bypass Salmonid Habitat Restoration and Fish Passage Implementation Plan (Implementation Plan (PDF, 2.6 MB)). The project design process has included working with state agencies, federal agencies, local agencies, reclamation districts, landowners, and non-governmental organizations to achieve mutual benefits or address potential negative impacts to other uses in the Yolo Bypass.

The process of obtaining environmental compliance for each project may be different because each project is unique. However, the general process includes: development of a project description, evaluation of potential project impacts and development of mitigation measures, preparation of environmental documentation or applications, submittal of documentation or applications to regulatory agencies, public notices and requests for comments, responses to comments, agency approval or environmental compliance completed.

The Implementation Plan also outlines the process for adaptive management. Following construction, projects will be monitored for their effectiveness at achieving performance goals. If it appears performance can be improved, potential changes to operations or project features and facilities would include consideration of monitoring results, additional investigation, and refined modeling.
