unlikely to alter the overall findings of the analysis . If this is required , CPE can provide an additional <br /> cost to develop this data suitable for incorporation into the analysis . <br /> Task 7 : Storm Damage Reduction Analysis <br /> The analysis of potential storm damages will be followed by an evaluation of the size of a beach fill that <br /> would be required to eliminate the potential damage identified with a particular storm return interval <br />. <br /> For example , if 5 structures in a given shoreline reach are identified as possibly being impacted <br />by a <br /> storm with a 10-year return interval , SBEACH would be re- run to determine the size of a beach fill that <br /> would be needed to eliminate that potential threat . This process will be repeated for each storm and <br /> each reach for which potential damages are indicated . The outcome of this analysis will be a list <br /> of <br /> beach fill dimensions needed in each reach to eliminate storm damage threats to structures for every <br /> storm return interval deemed to pose a potential threat . <br /> The results of this analysis can be used to formulate a beach nourishment strategy that would seek to <br /> equalize the magnitude of the storm damage risk for the entire County or at least reduce the risk to an <br /> acceptable level . The determination of what constitutes an acceptable level of risk would depend on <br /> priorities established by the County . This would likely be driven primarily by the cost of implementing a <br /> storm damage reduction project . To assist in this determination , CPE will include a range of possible <br /> construction costs for beach fill projects that would theoretically eliminate the risk of storm damage in <br /> each reach for all the return interval storms included in the analysis . CPE will prioritize higher <br /> probability of permitting projects in an effort to minimize costs to the County . <br /> Task 8 % Recreational Benefit Analysis <br /> Information regarding the usage of the beach , and by whom , is a critical aspect of developing a beach <br /> management plan . A recreational benefit analysis , combined with the storm damage reduction <br /> analysis , will assist the County in determining the economic viability of the various beach management <br /> strategies . The State of Florida is starting to incorporate these types of analyses when determining <br /> funding for various projects and the Chamber of Commerce can also use these studies to determine <br /> the benefit of beaches on the overall economy . <br /> The recreational benefit analysis will determine the recreational value of the County' s beaches . It is <br /> developed by determining the average value of a day at the beach multiplied by the number of days <br /> spent on average at the beach . The analysis will also investigate whether the beach goers are tourists <br /> or residents . <br /> Recreational benefits are difficult to define as use of the beach is free . Thus , the recreational benefit <br /> must be defined by asking beach users what they would be willing to pay to visit the beach . While <br /> access to the beach is free , there are associated costs such as food , fuel , and lodging . These <br /> also <br /> contribute to the value of the beach . <br /> CPE will assist the County in developing the questionnaires . It is expected that the County will conduct <br /> the surveys , which will be one week long and take place once in a summer month and once in a winter <br /> month . This will avoid the daily variability in beach usage by including the weekend as well as seasonal <br /> variability in the perceived value of the beach visit (tourists may deem the beach more valuable <br /> in <br />
