<br />Parameter AttributE. Codes (continued) <br /> <br />Maj or <br />Code <br /> <br />436 <br /> <br />437 <br /> <br />439 <br /> <br />Note: <br /> <br />Example: <br /> <br />10/93 <br /> <br />Minor <br />Code <br /> <br />00-- <br /> <br />00-- <br /> <br />0044 <br /> <br />DeSCI'iptor <br /> <br />Comments <br /> <br />l,OOC'-Foot <br />MarkEr <br />Identifier <br /> <br />Right justified; 2 digits. <br /> <br />River Mile <br />Marker <br />Ident ifier <br /> <br />Right justified; 2 digits. <br /> <br />Coincidence of <br />Stream, Channel, <br />or Shoreline <br />with Zone Break <br /> <br />This parameter code indicates the coincidence <br />of the stream, channel' or shoreline 1011ith a <br />zone break (which is shown in the Fl"od <br />Hazard Zones DLG). The linear shoreline <br />feature must be digitized from south to north <br />on the east coast of the United St:at,as and <br />from north to south on the west coast when in <br />coincidence with the zone break. This is the <br />only feature for which directionality is <br />important. It is shown as a combination of <br />FrS symbols L215 and L203, with the 3ymbol <br />for the zone break always shown on the <br />landward side of the shoreline. <br /> <br />If parameter attribute codes for cross section alpha charactl3rs <br />or ERM identifiers require more than 4 digits to represent the <br />data shown on the map, the parameter code will be repeated in <br />order to hold the additional digits. Thus, ERM number 101-12 <br />would be represented by the following parameter codes: 435 <br />0101, 435 0012, shown in the order the numbers occur on the map. <br /> <br />An Elevation Reference Mark number 12 with an elevat:ion valwa of <br />329.20 feet referenced to NGVD 29 would be expressed by the <br />following codes: 430 0350, 435 0012, 431 0329, 434 0020, <br />430 0610, 430 0620. The codes must be arranged in this ord,ar <br />(see Figures 4 and 5). <br /> <br />36 <br />
