Elevation or Floodplain Survey determines what?

• A. Locate property corners
• B. Determine parking layout
• C. Determine elevation for building plans and flood zone status
• D. Determine soil type

Answer: (C)

Elevation or floodplain surveys focus on vertical positioning relative to a standard datum, so they establish the exact elevations of the site and features. This information is essential for designing building foundations and first-floor elevations, guiding grading and drainage, and determining whether the site lies within a flood hazard area. Knowing the flood zone status informs construction requirements, materials, and insurance considerations, ensuring the design complies with regulations and protects the structure.

Other tasks described here belong to different survey types: locating property corners is a boundary survey that defines parcel limits; planning parking layout is part of site design and layout work; identifying soil type requires geotechnical or soils investigations.
