<br />Estimated futu~e flood crests and pertinent elevations
<br />
<br />at bridges within th~ study ~~ea ~re listed in Table 5.
<br />
<br />Of the
<br />
<br />va~ious bridgc$ cro~$ing the strearn5, most a~e obstructiv~ to the
<br />J:nt,,~mediate Regional Flood and even ~r" are ob~tructiv" to th~
<br />Standard l'ro)ect Flood. f'orst:udypurpo"esherein, it has been
<br />aS$wnnd that limited clogging would occur and all bridge struct:ures
<br />
<br />would stand intact.
<br />
<br />Significant changns in thi~ pre~is~, imposed by
<br />
<br />differing conditions of a future flood, could alter the c~tinated
<br />flood crests ..rod flood limits shown in the tables arod related plates.
<br />
<br />Future Flood Heights
<br />Averaged wat~r surface elev&tions for th~ Standard
<br />
<br />~roject Flood exc~ed those of the Intermediate Regional Flood by
<br />3 feet in the upper reach and 2.2 feet in the lower reach. Figures
<br />6 through 9 show the heights that would be rnached by the respec-
<br />tive future floods on facilities presently c~isting within the flood
<br />plains ccnsidered in the study.
