-Property Y is approximately 370' upstream of
the limit of detailed study (as measured along
the streamline). Using the profile below, we can
extrapolate the 100-year flood profile to determine
that the BFE for property Y is equal to 33',

-Property Z is approximately 700' upstream of
the limit of detailed study (as measured along
the streamline), and is therefore beyond the limit
of data extrapolation.
