This is a Cross Section Gradebook technical report containing surveyed elevation and coordinate data for Forest Road 11 on Mt. Baker. The report documents existing ground conditions and designed surface elevations at multiple stations along alignment "MAIN 11," spanning from station 800+00.000 to 802+00.000. Each station presents measurements at five feature points across the roadway width, including outside edge of gravel (EOG), edge to wheel (ETW), centerline (CL), and corresponding offsets ranging from -8 to +10 feet. The data includes elevation values in feet, precise Northing/Easting coordinates for geographic positioning, and slope measurements that vary from 0.02 to -0.035 across the alignment.

The report was generated on November 21, 2025, using input grid factor calculations with surface reference COR_MAIN_11-23.9, indicating this data supports the repair project referenced in solicitation 69056726B000002 for Mt. Baker Forest Road 11 MP 23.9 Repair. The elevation data ranges from approximately 842 feet to 852 feet across the surveyed section, with detailed cross-sectional profiles documenting both the designed construction surface and existing ground conditions. This technical documentation serves as the basis for construction planning and bid preparation for the forest road repair work managed by the Department of Transportation Federal Highway Administration.
