This 2024 Apex Benchmark Book is the initial benchmarks set in the Apex area. This Apex Benchmark Book is the result of the City of North Las Vegas Surveyors’ office. This primary vertical control network was established from holding the unilaterally recognized and common stable NGS Benchmark J 171 published elevation and checking into several other nearby NGS Benchmarks. 

 

In order to help identify subsidence in localized areas and to reduce, or eliminate human and computer error, the only effective use of this data for any project must include checking into multiple benchmarks in the network. Any property documented discrepancies between benchmark elevations as published herein, should be reported to the North Las Vegas City Surveyor’s office as soon as possible. 

 

Commencing with this publication, Northing and Easting coordinates are based upon the Nevada Coordinate Reference System, and are provided for each benchmark location as an aid to locate and verify that the proper benchmark is being utilized. Coordinates shown for each benchmark are approximate and must not be used as a basis for any horizontal survey control purposes. 

 

Where possible, benchmarks have been placed within public rights-of-way. The City of North Las Vegas does not grant or authorize access to benchmarks across public lands and/or privately owned or controlled property. It is the responsibility of the consultant performing the work to acquire proper access to any benchmark across these properties. 

 

Additions and periodic updates, utilizing the 2013 adjustment, will be published via the Internet. This office advises all users to check for revisions and/or updates prior to commencing work on any project.
