Tohono O’Odham Nation IFT Survey, Arizona

Wilson & Company provided cadastral boundary surveys and legal descriptions for the Integrated Fixed Towers (IFT) and Remote Video Surveillance System towers on the Tohono O’Odham Nation. The scope included 15 tower sites, 35 miles of access easements, and expansion of 79 low water crossings.

 

In addition to meeting all state statutes, the cadastral surveys were reviewed by the Bureau of Land Management (BLM) Cadastral Survey in conjunction with Bureau of Indian Affairs. Horizontal control was coordinated with state plane coordinates, NAD 83, and complied with Corps of Engineers 2nd Order, Class I standards. Our team surveyed centerline legal descriptions of roads and specific new design road locations for accessing each tower site, and prepared plats of the proposed 100-square-foot tower site. 

 

Surveyors monumented the corners of the tower sites to identify locations on the ground. In addition, the work included preparing legal descriptions and exhibits for 72 low water crossings, which expanded existing roadway easements to accommodate infrastructure improvements.
