A contour map provides information about:

• A. It Shows Hills, Valleys, Plateaus, And Other Patterns That May Affect Water Drainage, Runoff, Or Other Development Issues
• B. It Indicates Climate Patterns
• C. It Affects Lighting
• D. It Determines Property Lines

Answer: (A)

Contour maps show elevation changes across the land by drawing lines that connect points of equal height, revealing hills, valleys, plateaus, and the overall slope of the terrain. This topographic information is essential for understanding how water will move on the site, where drainage will occur, and how grading, drainage design, flood risk, and other development decisions will be affected. They do not depict climate patterns, lighting conditions, or property boundaries, which are shown on climate or weather maps, sun/shade analyses, and survey or plat maps, respectively.
