What type of lines are used to represent proposed contour lines?

Proposed contour lines are indicated using solid bold lines. This representation is important because it clearly differentiates proposed contours from existing features on a landscape plan. Solid bold lines provide high visibility and clarity, which helps in understanding the changes that are intended to be made to the terrain.

Using solid lines enhances the reader's ability to visualize the new elevations and slopes that will be established after construction, making it easier to plan and implement landscaping designs effectively. The thickness of the lines helps convey the significance of the proposed changes compared to other types of lines representing existing conditions or other features. In contrast, lines that are dashed, dotted, or thin may indicate different types of information or features, such as utilities or less significant elements, which is why solid bold lines are specifically chosen for proposed contours.
