waa-jeffer134309-2_ControlPoints.xlsx

This file is a Survey Control Point spreadsheet for the Two Trout Creek Culvert Replacement project (WA FLAP JEFFER 134309(2)). The document serves as a control sheet template for managing survey data in Excel format, with instructions for organizing and displaying survey control points across multiple worksheets.

The survey data includes eleven control points (numbered 22001 through 22009, plus TROUT1 and TROUT2) located in Washington State using the Washington North State Plane Coordinate System (NAD83 2011) with orthometric elevations based on NAVD88 GEOID18. Each point is marked with a 5/8-inch iron with FHWA aluminum cap and includes state plane coordinates (North and East), orthometric elevation, geographic coordinates (latitude and longitude), ellipsoid height, combined factors for distance calculations, and descriptive notes. The project uses US Survey Feet as the unit of measurement, with an epoch date of 2010.000 and a CADD system coordinate designation of WA83/2011-NF NSRS11. Field work dates were recorded as multiple entries, and the file was last revised on 12 August 2024 with a reference timestamp of 27 October 2025. This spreadsheet provides the foundational survey control data necessary for the culvert replacement project design and construction activities.
