To Reach Description
From Spur 330 and Bayway;Travel south on Bayway 1.35 miles to Schreck and turn right, then west on Schreck 0.7 miles to Bayshore and continue west on Bayshore 0.95 miles to the end of the road.Monument is in turnaround island on the curb 62.9’ south of the centerline of Bayshore.
  1. This is NGS' new classification system. Range VI indicates that this position meets the 0.02m-0.05m Accuracy Standard for Horizontal Position, Ellipsoidal Height, and Orthometric Height (elevation) at the 95% confidence level (m=meters).
  2. Horizontal Adjustment - This survey is constrained to the NGS Published Horizontal positions of the geodetic stations adjusted by NGS in 2001.
  3. Vertical Adjustment - This survey is constrained to the NGS Published Elevation for Northeast 2250 CORS ARP adjusted by NGS in 2001 and as published in PID AJ6430. Epoch Date 1997.00.
  4. The elevation shown equals the Ellipsoid Height minus Geoid Height (from GEOID99) plus a constant of 0.253 feet.
