of manufacturing, trade, tourism, and education has made the area 

 less dependent upon a single use of the estuary. In fact, the 

 relative value of the estuary to the entire population is shifting 

 toward recreation and aesthetic values. Indications of the value 

 of these recreational pursuits and aesthetic pleasures to the 

 general populace can be found in the estimated over $2 million 

 they are willing to spend annually to prevent pollution of the Bay 

 by municipal sources. 



The San Diego study does not provide a complete economic accounting 

 analysis of the estuary's total value but it does give some esti- 

 mates of the various components of the area's economy. Also, there 

 are estimates of the costs of abating Bay pollution from municipal 

 sources and estimates of the monetary benefits resulting from such 

 pollution abatement. 



Description of the Study Area 



Statistical Study Areas 



For purposes of the technical analysis, Bay-related land has been 

 divided into three geographic areas. Study Area I consists of 

 virtually all land immediately adjacent to and surrounding the 

 Bay extending approximately four to eight miles inland from the 

 Pacific Ocean. Study Area II lies immediately adjacent to Area I
