<br />Other Impacts <br /> <br />Other activities potentially impacted include sand and gravel operations, the construction <br />industry, and public recreation facilities. No data were available for the effects on sand and <br />gravel operations and the construction industry. The impacts of public recreation facilities <br />were documented through the recreation ~urvey (B.2). <br /> <br />The Division Between Listing and Critical Habitat <br /> <br />The Act requires that only the incremental impacts of proposed critical habitat designation be <br />quantified. To meet this requirement, a method had to be devised for determining the <br />percentage of an impact that was due to listing and the percentage that was due to designation <br />of critical habitat. This method is discussed in detail in Chapter TI-14 of Volume TI of the <br />Economic Analysis. By applying the percentage for the proposed critical habitat designation <br />to the direct impacts, the incremental impacts of critical habitat designation were determined. <br /> <br />Tables 6 and 7 present the percentage of impacts attributable to listing and critical habitat for <br />the Upper and Lower Basins if recovery were to occur by the year 2003. To derive the direct <br />economic impacts due to the listing of the endangered fishes, the residual percentages were <br />applied to the sectors where direct economic impacts were expected to occur. <br /> <br />Table 6.
