We study potential water resource development projects in Oregon and parts of southwestern Washington, analyzing and solving water resource issues of concern to local communities. These issues may involve navigational improvements, flood damage reduction, or ecosystem restoration

The Corps planning process follows a structured approach to problem-solving, using a rational framework for sound decision-making; it is also applicable for many other types of studies and we encourage its use. This six-step process is used for all Corps planning studies:

1. Identifying problems and opportunities
2. Inventorying and forecasting conditions
3. Formulating alternative plans
4. Evaluating alternative plans
5. Comparing alternative plans
6. Selecting a plan

Under a number of authorities, Planning Branch staff serve as both planners and managers for several types of projects, including:

• Individually authorized studies and projects
• Continuing Authorities Program
• Planning Assistance to States
• Flood Plain Management Services
• Lower Columbia River Estuary

General Investigation studies and projects, also known as Individually Authorized studies and projects, are the usual and most common way for us to help resolve a water resource problem. They involve jointly conducting a study with a sponsor and, if shown by the study to be feasible, the construction and implementation of the project. This requires Congress first authorize a feasibility study and second, separately authorize the project itself. The project studies and construction are cost-shared between the federal government and the sponsor, who usually pays all operations and maintenance costs. Project-specific federal costs for individually authorized studies or projects aren't limited, unlike the Continuing Authorities Program.
