 THIS BASE LINE WAS ESTABLISHED BY THE NGS, CDOT, DAVIS ENGINEERING SERVICES, AND LUCHETTI LAND SURVEYING.
 
 USER NOTES: CBL USERS SHOULD TAKE CARE IN PLUMBING OVER ALL POINTS. ELEVATIONS ARE FOR CBL USE ONLY. DUE TO THE FLATNESS OF THE
 GRADE, THE 450 M POINT SHOULD BE SETUP APPROXIMATELY 20 CM (8 IN) LOWER THAN THE O M POINT FOR INTERVISIBILITY BETWEEN ALL POINTS.
 
 THE BASE LINE IS ON CDOT PROPERTY IN THE RIGHT OF WAY. A PERMIT FROM THE ALAMOSA OR REGION 5 CDOT OFFICE IS REQUIRED TO BE IN THE 
 ROW.

 PROFESSIONAL LAND SURVEYORS OF COLORADO. 
 
 USER NOTES: CBL USERS SHOULD TAKE CARE IN PLUMBING OVER ALL POINTS. ELEVATIONS ARE FOR CBL USE ONLY. DUE TO THE FLATNESS OF THE
 GRADE, THE 150 M POINT SHOULD BE SETUP APPROXIMATELY 20 CM (8 IN) LOWER THAN THE O M POINT FOR INTERVISIBILITY BETWEEN ALL POINTS.

 THIS BASE LINE IS ON CORTEZ-MONTEZUMA COUNTY AIRPORT PROPERTY. YOU MUST CHECK WITH THE AIRPORT MANAGER AT 970-565-7458 BEFORE GOING
 TO THE BASE LINE.

 THE 1400-METER POINT IS A STANDARD NGS CALIBRATION BASE LINE DISK STAMPED "1400 M 1989" SET IN THE TOP OF A 0.5 M (1.7 FT) DIAMETER
 CONCRETE POST FLUSH WITH THE SURFACE OF THE GROUND.  IT IS 43.6 M (142.9 FT) SOUTH-SOUTHEAST OF THE NORTHEAST CORNER OF RUNWAY 16-
 34, 14.8 M (48.5 FT) EAST OF THE EAST EDGE OF RUNWAY 16-34, 54.1 M (177.4 FT) WEST OF BARBED WIRE FENCE, 1.2 M (3.9 FT) EAST OF A 
 FIBERGLASS WITNESS POST, AND 1.2 M (3.9 FT) WEST OF A FIBERGLASS WITNESS POST.
