Today the U.S. Navy has modern facilities, equipment, training 

 camps, research laboratories, and a total naval personnel of approxi- 

 mately 170,000 persons. An estimated 215,000 dependents of these 

 170,000 naval men live in San Diego County. The majority of the 

 100,000 shore-based military personnel are based at San Diego installa- 

 tions or Camp Pendleton. Additional naval personnel are based at the 

 Ream and Miramar Naval Air Stations. 



Density 

 Approximately 73 percent of the county's civilian population lives 

 within 20 miles of San Diego Bay. Study area I, adjacent to the bay, 

 and with less than 1 percent of the county's total land area, has ap- 

 proximately 19 percent of the civilian population; Study area II, 

 immediately adjacent to study area I with 6.9 percent of the county's 

 nonmilitary land area, has 52 percent of the civilian population. In 

 other words, the population is more concentrated towards the bay, and 

 population density is inversely proportional to the distance from the 

 bay. Figure IV.3.4 on page 176 shows the anticipated population 

 growth of the three areas. 



Municipal wastes 



By the mid-1950's wastes discharges into San Diego Bay began to 

 exceed the assimilative capacity of the waters. In late 1960 local voters 

 passed a $42.5 million bond issue for the construction of new waste 

 treatment facilities. As a result of the new facilities, no domestic 

 wastes have been discharged to San Diego Bay since 1964. All sewage 

 is now collected and pumped to the treatment plant from which it is 

 discharged into the Pacific Ocean. 



Table IV.3.21 shows the estimated annual dollar costs and benefits 

 involved in the bay cleanup. Annual costs of debt service, and opera- 

 tion and maintenance of the facilities range from $2,3 million in fiscal 

 year 1967-68 to a projected $3.3 million in the year 2000. These esti- 

 mated costs have been adjusted to exclude costs not borne by the local 

 residents or those costs not exclusively associated with bay cleanup. 

 In other words, debt service costs associated with the Federal contri- 

 bution for construction have been excluded along with those costs re- 

 quired whether the wastes are disposed of in the bay or in the ocean.
