48 FATTTICAL CHART MANUAL 



DUCK BLINDS 



A duck blind is not charted unless it is of a permanent nature and a danger to navigation. 



FERRIES (H-19) 



Ferry terminals shall be labeled with the word "Ferry." Ferry routes should not be charted 

 for great distances but may be shown for short distances out from the slip by a magenta dashed 

 line. 



The black dashed-line symbol should only be used when charting a cable ferry.

CITIES AND ROADS (Fig. 1) (H-1; I-l, -la) 



On existing charts, cities, towns, and roads have been represented by road patterns and 

 symbolized by single or double lines depending on the scale of the chart. For instance, on 

 charts larger than 1 :40,000 scale, roads in open country, cities, and towns are shown by double 

 lines. On charts 1:40,000 to 1:99,000 scale, streets in cities and towns are shown by single 

 heavy lines while the roads in open country are shown by double lines. On charts 1 : 100,000 

 and smaller scale, only single heavy lines are used. 



On all New Charts and Reconstructions, both large and small scale, consideration shall be 

 given to charting the areas of cities and towns by a screening and showing only the major 

 highways leading to or through the cities by single heavy lines. However, this new treatment 

 should not replace the older road pattern symbolization on all charts. Both methods have 

 their merits and on some charts even a combination of the two methods may be used eflFec- 

 tively. 



Highways in general shall not be shown on charts of smaller scale than 1 : 250,000. Only 

 through or connecting public highways, and roads leading from such highways and terminat- 

 ing at the shore, shall be shown. Private roads leading from public highways to a building 

 shall be omitted. In cities, only streets which are actually constructed and in use are to be 

 charted. Omit some streets, as necessary, to avoid crowding. Numbers and names of im- 

 portant U.S. highways shaU be charted when the information is available. 



When double-line streets and roads are to be charted, they shall be shown on the Drawing 

 by a single line with a note to the engraver to engrave standard double lines. When so desig- 

 nated, the line should represent the center of the road. Care must be taken to see that it is 

 possible to engrave a double line where a single line is drawn and that too many streets are not 

 shown. Highway interchanges and odd road intersections will be shown with double lines to 

 aid the engraver. When single-line roads are shown on a Drawing and there is a possibility of 

 their becoming confused with contours, streams, or other detail, they shall be labeled on the 

 Drawing with the letters "Rd" in blue ink. 



Roads shown by dashed lines on the survey sheets are not to be charted unless they are 

 considered of some importance, in which case they must be charted by solid lines. 



Trails shall not be shown on the charts.
