About this file
This Vertical Alignment Review Report is a technical document for the Umpqua ERFO Repairs 2022 highway project, detailing precise road design specifications for a section of highway. The report provides a detailed vertical alignment analysis for the ALI_MAIN_4710 and PRO_MAIN_4710 alignments, documenting elevation changes across multiple linear and parabolic elements from station 100+11.92 to 102+82.69. The vertical profile shows a series of grades ranging from -0.052 to -0.018, with specific metrics including tangent lengths, vertical point of curvature (VPC), vertical point of intersection (VPI), and vertical point of tangency (VPT) locations, demonstrating a gradually descending road profile from an initial elevation of 1425.460 feet to a final elevation of 1414.928 feet.
