About this file
This document is a subsurface utility survey map showing designated underground utilities at the North Las Vegas VA Medical Center, located at 6900 North Pecos Road, North Las Vegas, Nevada. The survey was completed on December 17, 2023, by Subsurface Utility Imaging, LLC (a division of Blood Hound), and covers a portion of the medical center property at a scale of 1 inch equals 40 feet.
The map identifies multiple types of subsurface utilities including sanitary lines with manhole rim elevations (2058.60, 2058.70, and 2061.70), underground electric lines (UGE), underground communication lines (COMM), water lines (W), and unknown features (UNK). The survey utilized radio frequency (RF) and ground penetrating radar (GPR) methodologies to identify and map these utilities. The document includes critical disclaimers that the subsurface utility information is for informational use only and should be verified through vacuum excavation or other non-destructive techniques. Utility depths shown are approximate and derived from RF methodologies. The survey is referenced to NAD83/2011 horizontal datum and NAVD88 vertical datum using the Nevada State Plane Coordinate System (East Zone). The document notes that additional subsurface utilities exist beyond the investigation area and that state law requires contacting 811 before any site excavation occurs.
