Benefits shown in table IV.3.21 are those directly attributable to 

 water related recreational activities. Estimated direct recreation bene- 

 fits range from $6 million in 1967-68, to $12.0 million in the year 2000. 

 These benefits are restricted to recreational aspects only and do not 

 include the impact of money spent for recreation on the associated 

 parts of the economic system.

Military 

 The U.S. Navy and Marine CJorps contributed $1.2 billion to the 

 economy of San Diego County in 1967. This was an increase of 17 per- 

 cent over 1966. Major factors in the increase were greater military 

 construction, the Vietnam war buildup, and an increasing number of 

 dependents and retired military men moving into the county. As de- 

 scribed previously, an estimated 170,000 naval men and Marines are 

 stationed at military facilities in San Diego County. An estimated 173 

 Navy ships are based in San Diego. On an average, 90 Navy ships 

 operate out of San Diego harbor every day. The Navy spends approx- 

 imately $300 million to support these ships and the several other naval 

 commands in the community. For utilities (gas, electricity, water, 

 phone) alone, the Navy spends more than $7 million every year. The 

 Navy also employs civilian, civil service employees, and blue collar 

 workers who received compensation of $201.8 million in 1967. Military 

 construction in San Diego County averages more than $20 million 

 annually.

Maritime coniTnerce. — ^The continually expanding growth (figure 

 IV.3.5, p. 178) of the maritime industry's use of San Diego as a harbor 

 necessitates the construction of a new terminal every 10 years. 



For fiscal year 1967-68, Marine terminals reported a total revenue 

 tonnage via port of San Diego of 1,107,060 tons. The total value of 

 cargo was $269.3 million, including bunker fuels. Inbound cargo was 

 valued at $203.3 million, and outbound at $65.6 million. The largest 

 single import category was toys and novelties with a value of $38.3 

 million ; second largest item imported was textile and clothing valued 

 at $30.2 million. The largest export category was household goods 

 with a value of $15.2 million ; the second largest category among ex- 

 port goods was transportation equipment and machines valued at 

 $13.1 million. In terms of tonnage, however, lumber had the greatest 

 import tonnage, and potash the greatest export tonnage. 



Shipbuilding. — The shipbuilding industry provides employment for 

 five times as many workers today as it did less than 20 years ago. The 

 current labor force of almost 4,000 workers is expected to increase to 

 6,750 hj the year 1990. This increase would, however, represent no 

 change in the industry's percentage of the total San Diego County 

 labor force, and is expected to remain constant at 1 percent. The eco- 

 nomic value of shipbuilding has grown from $6.5 million in 1950 to 

 $91.7 million in 1967. 



Some 20 shipbuilding and repair firms scattered throughout the 

 bay conduct operations ranging from the construction and repair of 

 large vessels to alterations on small fishing boats. Commercial ship- 

 building and repair operations have increased as the result of the clos-
