A 3D Topographic Survey (With Elevations) provides a detailed three-dimensional representation of the physical features and terrain of a property. Unlike a boundary survey, this service focuses exclusively on the existing conditions within and around the site, capturing both horizontal and vertical data. It is a crucial tool for architects, engineers, developers, and contractors who require accurate site information for planning and design.

The survey typically includes:

• A plan view map of the property showing visible above-ground improvements such as buildings, fences, curbs, driveways, sidewalks, utilities, and vegetation.

• Vertical data collection using survey-grade instruments to depict spot elevations, contour lines, and terrain relief.

• Identification and location of surface features such as utility structures, drainage patterns, and grade changes.

• A deliverable that provides both visual clarity and digital compatibility for design, typically including CAD or GIS-ready files.

This survey is most commonly used for:

• Engineering and architectural design requiring accurate terrain and grade information.

• Drainage and grading analysis, including stormwater management planning.

• Construction planning, allowing contractors to understand existing elevations and slopes before excavation or site work.

• Municipal permitting requirements that mandate elevation data as part of a development or improvement plan.

Important Limitations:

• This survey does not establish, verify, or depict property boundaries. If legal boundary lines or monuments are required, a Boundary & Topographic Survey should be requested.

• Underground utilities are typically not included unless visible or specifically requested with supplemental locating services.

• The accuracy of terrain depiction will depend on the contour interval requested (e.g., 1’, 2’, or 5’ contours), which should be discussed with the surveyor in advance.
