1. Harbors Module NH4: Reformulation – Optimization, Incremental Analysis and Selection of the NED Plan

2. Student Learning Objectives Student will be able to: • Analyze last added reaches • Apply the concept of incremental analysis • Identify an NED plan • Deal with locally preferred plans

3. Reformulation • Process of improving alternative plans • By adding, re-scaling and eliminating uneconomic increments • May be based on things like ship simulation • Increase the ability to meet the Formulation Criteria • Completeness • Effectiveness • Efficiency • Acceptability

4. Selecting the NED Plan • Evaluate plans by comparing them to the without project condition • Maximize net NED benefits through optimization and incremental analysis • Identify the NED plan • Will the NED Plan normally be selected as the recommended plan?

5. Exercise: Purposes: • To provide an understanding of optimization, incremental analysis and identification of the NED plan. • To demonstrate the development of alternative plan formulation strategies in the establishment of an array of alternative plans

6. Exercise: • Assign roles to the members of your group • Port – Wants 50 foot depth to compete with other ports • Upstream Terminal Operator – Wants consistent depth in harbor • Pilots Association – Wants extra width • Corps Planners – Need to follow Corps policies • Based on the information provided • Develop formulation strategies for the final array that will facilitate trade-off analysis • Determine appropriate depths, widths and reaches for each plan in the final array • Identify the NED Plan

7. Exercise: • State the number of plans in your final array • Describe the plans in terms of formulation strategy, depth, width and reaches • Identify your NED plan

8. Exercise: • Did you do any reformulation? • Are there any plans that could not be recommended? • How would a Locally Preferred Plan (LPP) be selected?

9. Locally Preferred Plan • If the local sponsor desires, a locally preferred plan may be formulated that addresses other local objectives and constraints. • The selection of a locally preferred plan may deviate from the NED Plan if requested by the non-Federal sponsor and approved by ASA(CW)

10. Locally Preferred Plan – Cost Sharing If the locally preferred plan has: • Larger costs than the NED plan • Incremental cost is entirely a non-Federal responsibility • Special case - NED Plan exception granted by the ASA(CW) and the costs are then shared at the same percentage basis as the NED plan • Smaller costs than the NED plan • Normally be granted an exception to NED plan selection • Costs are then shared at the same percentage basis as the NED plan

11. Comparison of Plans Where LPP>NED

12. Comparison of Plans Where LPP<NED

13. Exercise: - NED Solution Moody River Existing Width • Total Benefits for 50 feet downstream and 48 feet upstream $45,280,546 • Total Costs for 50 feet downstream and 48 feet upstream $24,235,384 • Total Net Benefits $21,045,162 Or……… • Net Benefits of 48 feet upstream and downstream $20,936,836 • Net Benefits between 48 feet and 50 feet downstream $108,326 • Total Net Benefits $21,045,162

14. Take Away Points • Incremental analysis of widths and reaches is required to identify the NED Plan. • While a study may recommend a locally preferred plan, the NED Plan normally sets the limit on the Federal investment. • A locally preferred plan can be less than the NED Plan and still have WRDA ’86 cost sharing.

15. Where We are Going • Next, we’ll start a section on multi-purpose planning. • The first module will cover project purposes, emphasizing the authorities and policies of those purposes that have not been covered thus far in this workshop.

16. Challenge: Why do you formulate alternative plans even when the local sponsor has “decided” on a plan?
