This is a cross-section gradebook report providing surveyed geometric data for Forest Road 11 at Mile Post 23.9 on the Mt. Baker project. The report documents existing ground elevations, design layer specifications, and coordinate data (Northing/Easting) at ten survey stations spanning from Station 800+00.000 to Station 802+00.000, with measurements recorded in feet. The document contains detailed offset measurements, design elevations, and slope information for multiple features including slope stakes, edge-of-gravel layers, edge-of-traveled-way layers, and centerline layers on both the left and right sides of the roadway alignment.

The gradebook appears to serve as a baseline survey document for the Forest Service road repair project outlined in Solicitation Number 69056726B000002 (WA ERFO FS MTBKR605 2022-1(3)) administered by the Department of Transportation Federal Highway Administration. This technical data would be essential for contractors preparing bids on the road reconstruction work, providing the existing ground conditions and design specifications necessary for estimating earthwork quantities, material requirements, and construction methodology.
