This is a Survey Control Point spreadsheet that documents precise geographical and elevation data for the Crown Point Trail and Parking Area project located in Idaho. The file contains a control sheet template with survey point coordinates, elevations, and reference information used for construction planning and execution.

The spreadsheet lists 13 survey control points (numbered 23101 through 23602, plus a reference pier) established during field work conducted in August 2023, with final adjustments completed on August 29, 2023. Each point includes State Plane Coordinates (Idaho West SPCS NAD83 2011), orthometric elevations, geodetic coordinates (latitude/longitude), ellipsoid heights, combined factors for distance verification, and point descriptions. All control points are marked with 5/8-inch iron rods with FHWA aluminum caps, with elevations ranging from 4,835.134 to 4,865.957 feet. The vertical datum is based on a Safety of Dams Monitoring published elevation of 4,845.609 feet for the reference pier. Project units are in US Survey Foot, using the CADD system coordinate system ID83/2011-WF NSRS11 (NAD83/2011) for Idaho West Zone. This control sheet serves as the baseline survey data for the design and construction phases of the Crown Point Trail and Parking Area project being administered by the Department of Transportation Federal Highway Administration.
