The NFIP does not differentiate <br />between marunade and natural shorelines, or <br />perennial and non~perennial drainage. These <br />features are shown by FIS symbol L21S. <br /> <br />This code identifies a line, whose source is <br />the lOOK USGS DLG, that defines the location <br />of a small stream (shown ,by a single line <br />that represents the stream centerline) or a <br />large stream (shown by double lines that <br />represent the approximate locations of the <br />stream banks). This code also identifies <br />lines that represent the shorelines of bodies <br />of water of any size (ponds, lakes, gulfs, <br />oceans). The NFIP does not differentiate <br />between man-made and natural shorelines, or <br />perennial and non-perennial drainage. These <br />features are shown by FIS symbol L21S. <br /> <br />This code identifies a line, whose source is <br />the 24K USGS DLG, that defines the location <br />of a small stream (shown by a sin,gle line <br />that represents the stream centerline) or a <br />large stream (shown by double lines that <br />represent the approximate locations of the <br />stream banks). This code also identifies <br />lines that represent the shorelines of bodies <br />of water of any size (ponds, lakes, gulfs, <br />oceans), The NFIP does not differentiate <br />between manmade and natural shorelines, or <br />perennial and non-perennial drainage.
