What do long broken lines parallel to the property lines on a site plan represent?

Long broken lines that run parallel to the property lines on a site plan typically indicate easement limits. Easements are legal rights to use someone else's land for a specific purpose, such as utilities or access. These lines help to visually denote areas where these rights exist, ensuring that anyone reviewing the site plan understands where easements are located in relation to the property's boundaries.

The other types of lines mentioned—property boundaries, setback lines, and survey lines—have distinct appearances and purposes. Property boundaries are usually represented by solid lines, setback lines are often shown as dotted or dashed lines that indicate the minimum distance required between structures and property lines, and survey lines relate to the measurements and layout of property during a survey process, which typically do not follow the characteristics of long broken lines seen with easements. Understanding these distinctions is vital when interpreting site plans accurately.
