 able to general -car 0:0 shippino- and industries dependent on shipping. 

 This represented a payroll of about $820 million.

By tonnage, the principal cargo passing through the San Francisco 

 Bay is petroleum. This tonnage is expected to increase significantly in 

 the future, and bring with it deep draft tankers with drafts as much 

 as 60 feet. At this time, however, there are no reliable estimates of the 

 impact of this future increase in San Francisco port traffic, nor are 

 there reliable methods to measure the conflicting values and costs pre- 

 sented by this phenomenon. 



NATIONAL DEFENSE 



The use of estuarine and coastal ports has always been an essential 

 need of the national defense system for the movement of weapons, 

 troops, and supplies to and from overseas bases and operations zones. 

 Table IV.4.6 itemizes amoimts of military cargo and passengers trans- 

 shipped by area for 2 recent years. Tons and dollar value of cargo went 

 up appreciably from fiscal year 1966 to fiscal year 1967, while num- 

 bers of passengers decreased. The impact of the Vietnam war can be 

 seen in the comparison of figures for the Eastern and Western areas 

 for the 2 years. However, it is a primary item of Defense policy that 

 facilities be available for use in all coastal areas to meet particular 

 military logistics requirements at any time. 



Future demands for the use of estuarine and coastal areas by the De- 

 partment of Defense are difficult to project since they will vary greatly 

 according to the state of international affairs and the impact of tech- 

 nological developments. The Office of Business Economics has re- 

 garded military employment as a constant after the year 1980 because 

 of this lack of predictability. The examples given in chapter 3 of the 

 impact of Naval activity on Narragansett Bay and San Diego Bay 

 give at least a general idea of the magnitude of present and future 

 military activities in the Naition's estuaries.
