The base flood elevation (or flood protection elevation) is the
water level for the 100-year flood assuming only that, encroachment
on the flood plain that existed when the FIRM was adopted (May
q 7 r;
2
2, 1977). Additional and complete encroachment to the floodway
encroachment limit will cause the water level to surcharge one
foot or less above the flood protection elevation. A Special
Use'Permit shall never cause a surcharge to a level higher than
J
the one foot or less described above.
Considerationofthe effects of a proposed use shall be based on ` -
a reasonable assumption that there will be an equal degree ofl
encroachment extending for a''significant reach on both sides of
the stream.
