PER THE 1-405 SR 167 IC/DC PROJECT REFERENCE DOCUMENTS SECTION 2.5.2.1: WSDOT PREPARED AND UPDATED MAPPING FOR PROJECT USING 2013 AERIAL PHOTOGRAMMETRY AND TOPOGRAPHIC SURVEYS. PRIMARY AND SECONDARY SURVEY HORIZONTAL AND VERTICAL CONTROLS WERE ESTABLISHED BY WSDOT WITH GIPS EQUIPMENT IN WASHINGTON STATE COORDINATE SYSTEM, NORTH ZONE. HORIZONTROL CONTROLS ARE BASED ON THE NORTH AMERICAN DATUM OF 1983 (NAD 83/91)AND VERTICAL CONTROLS ARE BASED ON NORTH AMERICAN VERTICAL DATUM OF 1988 (NAVD 88) AND AS SPECIFIED AS <0.005M (± LINEAR UNCERTAINTY). WSDOT HAS SUPPLIED AN ELECTRONIC DIGITAL TERRAIN MODEL (INROADS FORMAT) AND 2D MICROSTATION .DGN FILES COMPRISED OF PHOTOGRAMMETRIC AND TOPOGRAPHIC SURVEY DATA IN PROJECT DATUM COORDINATES CONVERTED FROM STATE PLANE COORDINATES USING A COMBINED FACTOR OF 1.000006285.
