Topographical maps are a 2-dimensional representation of a 3-dimensional land surface. They show the natural and man-made features of the land surface distinguished by position, relation, size, shape, and the elevation of the features, providing up-close visual detail.
A topographical site survey locates all surface features on the property as well as providing ground contours and elevations. The final product is a map showing any fences, walls, buildings, sheds, driveways, streets, curbs & sidewalks, pools & patios, walkways, stairs, utilities and trees on the property. It will also show elevation references and natural features, including ground contours.
Topographic surveys are generally necessary for:
- Extensive remodeling and additions to an existing residence
- Landscaping or pool construction design
- Slope-stabilization projects
- Grading and drainage or other civil engineering design
- New construction design
- Road design or improvements
- Utility design or improvements
