NOTES 



1. Distance measurements must be horizontal level lines. 



2. If profiles are taken instead of distance measurements, obtain elevations 

 at changes in grade or every 20 feet. 



3. If ground has low relief, use judgment in spacing out profile points. 



4. All elevations refer to International Great Lakes Datum as measured above 

 mean water level at Father Point, Quebec (I.G.L.D., 1955).
