This is an engineering design document—specifically a plan and profile sheet for a construction project at the North Rim of Grand Canyon National Park. The document is prepared by HDR Engineering, Inc., a prime contractor located in Denver, Colorado, with project leadership by Gough/Glover and J. Glover. The sheet shows detailed engineering drawings including an aerial site photograph, profile cross-section (Profile D), and a waterline fitting table for a Total Closed Loop (TCWL) connection at station 530+00 to 530+26. The technical specifications indicate a 34-foot, 4-inch diameter High-Density Polyethylene (HDPE) pipe at grade with specific elevation markings (ranging from 4,835 to 4,860 feet) and connection points to existing infrastructure at the pipe exit.

The waterline fitting table provides specific geographic coordinates (northing and easting) for two connection points, with point 22 designated as an intercept supline featuring a 3.5-inch reducer and cap to replace existing 8-inch TCWL with a 4-inch hope connection, and point 23 specified for TCWL connection. General notes on the sheet address construction width parameters and pipe length calculations. The document is identified as drawing number 182752, sheet 16 of 113, titled "Plan and Profile D" for the North Rim—Grand Canyon National Park project, dated June 2026.
