Section VII— NED Benefit Evaluation 

 Procedures: Transportation (Deep- 

 Draft Navigation) 



2.7.1 Introduction. 



This subpart presents the procedure for measur- 

 ing the beneficial contributions to national econom- 

 ic development (NED) associated with the deep- 

 draft navigation features of water resources plans 

 and projects. Deep-draft navigation features include 

 construction of new harbors and channels and im- 

 provements to existing or natural harbors on the 

 sea coasts to meet the requirements of ocean- 

 going and Great Lakes shipping. Harbor improve- 

 ments include such structural projects as the con- 

 struction of breakwaters and jetties to protect ex- 

 posed harbors and the provision of entrance chan- 

 nels, interior channels, turning basins, and anchor- 

 age areas. Nonstructural deep-draft measures in- 

 clude improved traffic management and pilotage 

 regulations. 



2.7.2 Conceptual basis. 



The basic economic benefits from navigation 

 management and development plans are the reduc- 

 tion in the value of resources required to transport 

 commodities and the increase in the value of 

 output for goods and services. Specific transporta- 

 tion savings may result from the use of larger ves- 

 sels, more efficient use of large vessels, more effi- 

 cient use of existing vessels, reductions In transit 

 time, lower cargo handling and tug assistance 

 costs, reduced interest and storage costs such as 

 from an extended navigation season, and the use 

 of water transportation rather than an alternative 

 land mode. Principal direct benefits are categorized 

 as follows: 



(a) Cost reduction benefits. If there is no change 

 in either the origin or destination of a commodity, 

 the benefit is the reduction in transportation costs 

 of quantities of the commodity that would move 

 with and without the plan resulting from the pro-
