How is the finished grade represented on a plot plan?

The finished grade on a plot plan is represented by solid contour lines. These contour lines illustrate the elevation and the topography of the property, indicating how the land has been graded and shaped for construction. Solid contour lines provide a clear visual representation of changes in elevation, allowing builders and architects to understand the project's site conditions. They help in planning drainage, landscaping, and the placement of structures in relation to the land's natural contours.

By using solid lines for finished grades, it distinguishes them from other types of lines that may represent existing grades, vegetation, or other non-finished features of the site. This clarity is essential for proper interpretation and execution of the construction plans.
