Estimates of economic benefits to local residents indicated in table 

 IV.3.20 are of particular importance to the area because its present 

 relatively low economic status indicates the local population is unable 

 to better itself economically from pursuits other than those related 

 to the estuary. However, in addition to the economic improvement 

 which may be anticipated locally, consideration also should be given 

 to the recreational advantages afforded by the estuary to local citizens. 

 It is reasonable to expect that a direct relationship exists between 

 socioeconomic level and the distance which the members of the pop- 

 ulation will travel to fill their recreational needs ; that is, the lower a 

 person's income the shorter distance he is likely to travel for purposes 

 of recreation. Therefore, even with the increasing mobility which 

 Americans have experienced in the last several decades, there is no 

 question but that availability of adequate water recreational facilities 

 near the local population is of incalculable benefit to those local 

 citizens. These benefits can be expected to increase with the shortened 

 workweek predicted for the future as well as the increase in economic 

 well-being projected for the population with ready access to the 

 Apalachicola Estuary. 



SAN DIEGO BAY (IV-3-3 ) 



The San Diego area is an example of the multiple uses and develop- 

 ment of an estuarine system. The basic development and growth of 

 San Diego is attributable to the military uses of its deepwater estuary. 

 However, later diversification of the economy into areas of manufac- 

 turing, 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 account- 

 ing 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.
