A stake marked "OF 65' CL C-3.5" means that the stake is offset what distance from the centerline stake?

The notation "OF 65' CL C-3.5" indicates that the stake is offset from the centerline (CL) by a distance of 65 feet. In this context, "OF" stands for "Offset," which specifies how far the stake is positioned from the centerline designation. The "CL" refers to the centerline, which is a reference line used in construction and engineering to establish locations for various components of a project. The figure "65'" directly corresponds to the actual offset distance.

Thus, the correct understanding of this designation demonstrates that the stake is precisely 65 feet away from the centerline, which aligns with the answer provided. The other options do not accurately reflect the distance indicated by the stake’s marking, as they either underestimate or overestimate the offset, which is critical for ensuring proper alignment in construction tasks.
