Module NH3: Formulation – Measures, Strategies and Plans

NH3 - 2 BU ILDING STRONGSM

Student Learning Objectives

The student will be able to:

Identify management measures

Develop plan formulation strategies for navigation projects

Use strategies to formulate alternative plans

Explain the basic economic evaluation of navigation plans

NH3 - 3 BU ILDING STRONGSM

Deep-Draft Navigation Formulation Meets objectives

Accommodate larger ships Reduce traffic delays Increase safety

Recognizes constraints Resources – endangered species Institutional – disposal Financial – sponsor’s resources

Develops Management measures Plan formulation strategies Plans

NH3 - 4 BU ILDING STRONGSM

Approach to Formulation

Interview experienced and/or technical experts

Consult documents of similar studies

Group exercises – brainstorming

NH3 - 5 BU ILDING STRONGSM

Identifying Management Measures

Structural measures

Nonstructural measures

Exercise: Let’s Brainstorm a list

NH3 - 6 BU ILDING STRONGSM

Structural Measures

Channel deepening and widening

Anchorages

Breakwaters

Berthing areas

Mooring areas

Disposal areas

Methods e.g phased construction

NH3 - 7 BU ILDING STRONGSM

Structural Measures (Breakwater, confined disposal site)

NH3 - 8 BU ILDING STRONGSM

Structural Measures (Detached straight breakwater)

NH3 - 9 BU ILDING STRONGSM

Structural Measures (Small boat harbor associated with deep draft)

NH3 - 10 BU ILDING STRONGSM

Structural Measures (Harbor deepening)

NH3 - 11 BU ILDING STRONGSM

Structural Measures (Dredging & Beach Nourishment)

NH3 - 12 BU ILDING STRONGSM

Structural Measures (Jetty Construction)

NH3 - 13 BU ILDING STRONGSM

Nonstructural Measures Operational practices

Traffic Controls

Changes in operating procedures (tides, lightering,etc)

Modification of local service facilities

Storage

Berthing

Structural measures by non-Federal interests are often referred to as nonstructural measures.

NH3 - 14 BU ILDING STRONGSM

Develop Plan Formulation Strategies

Strategies would reflect the desires of the non- Federal sponsor and other stakeholders Avoid high cost relocations Avoid significant environmental resources Serve different terminals/ports Evaluate the impacts of adding channel reaches Addressing different combinations of the planning objectives Remember disposal options and beneficial uses Make sure that all stakeholders are involved in the

development of formulation strategies

NH3 - 15 BU ILDING STRONGSM

Formulate Alternatives Combining measures – examples

Channel deepening with anchorages

Channel deepening with phased widening

Traffic management with anchorages

Channel deepening with beneficial uses of dredged material

Synergies – look for opportunities to serve other needs

NH3 - 16 BU ILDING STRONGSM

Evaluation of Alternatives Verify technical/engineering feasibility

Evaluate environmental impacts

Perform economic analysis of costs and benefits

Account for uncertainty through sensitivity analysis

NH3 - 17 BU ILDING STRONGSM

NED Costs Construction costs

General Navigation Facilities Project features – breakwaters, jetties, etc. Dredging and disposal Real estate Mitigation

Local Service Facilities

Operation and maintenance costs Interest during construction Associated costs

NH3 - 18 BU ILDING STRONGSM

Associated Costs – What Are They and Who Pays Frequently overlooked because

Often not paid by non-Federal partner Incurred by project users

Associated with the general navigation feature to achieve the estimated benefits

Represent costs not otherwise accounted for Variable costs of doing business May not be self-liquidating Related to project throughput

NH3 - 19 BU ILDING STRONGSM

NED Benefits – Basically Savings in Transportation Unit Costs Cost Reduction Benefit (same origin-destination and same

mode). Reductions in costs incurred from trip delays Increased loads in existing ships Reduction in costs because larger or longer tows Reduction in costs because of using larger ships

Change in mode benefits

Shift of origin-destination benefits

Induced movement benefit (if you build it, will they come?)

Reduction in vessel damages

NH3 - 20 BU ILDING STRONGSM

Take Away Points Plan formulation is the art of creating plans to address the

objectives and constraints related to navigation problems and opportunities

Don’t reinvent the wheel. Use previous studies, conduct interviews and brainstorm.

In developing plan formulation strategies, you need to understand the basic policies affecting plans for navigation improvements. Be sure to consider timing as well as the measures themselves.

Breakpoints in costs are especially important to formulation and associated costs need to be included in the analysis

NH3 - 21 BU ILDING STRONGSM

Where We are Going

Next, we’ll cover reformulation to optimize the alternative plans.

We’ll cover incremental analysis and learn to identify the NED plan.

We’ll also learn how to

deal with locally preferred plans

NH3 - 22 BU ILDING STRONGSM

What issues would arise in having formulation accomplished as an in-kind service?
