What is a contour map?
Large Scale Contour Mapping of Bakken Production Sties
“A contour line represents the tracing of one constant elevation above or below a certain datum. In other words, every point on any one contour line is at the same elevation throughout that contour line. Although the datum may be an assumed point of elevation accommodating the job, it is more often based upon Mean Sea Level”
-Gurdon Wattles, Survey Drafting

Need for contour maps Storm water drainage and spill prevention
plans regulated by North Dakota Department of Health
Storm Water Pollution Prevention Plan (SWPPP) “Provide a site map showing … drainage patterns, including flow direction, dividing lines, existing grade and final grade”
