Phoenix District Office

The Phoenix District Office is comprised of the Hassayampa and Lower Sonoran Field Offices which also includes the Agua Fria National Monument and Sonoran Desert National Monuments, respectively. 

Hassayampa Field Office

The BLM Hassayampa Field Office manages nearly 1 million acres north of Interstate 10 and an additional 725,000 acres of subsurface estate (mineral interests), including the 70,900 acre Agua Fria National Monument.  Public lands within this field office are near developed and expanding communities and are heavily used.  The lands are managed for multiple use and provide diverse recreational opportunities, mining, wildlife habitat, grazing, and wilderness, all overlaying a rich cultural past.  The field office also oversees five wilderness areas, one river segment suitable for Wild and Scenic River Designation, and one Area of Critical Environmental Concern.  Additionally, it is home to the Harquahala National Back Country Byway, the Black Canyon National Recreation Trail, and has one property listed on the National Register of Historic Places.

Lower Sonoran Office

The BLM Lower Sonoran Office manages 1.4 million acres of public land in south-central Arizona, including the half million acre Sonoran Desert National Monument, located 60 miles southwest of Phoenix.  The Monument contains biologically diverse national communities, including large Saguaro cactus forests and contains many significant archaeological and historic sites.  In an effort to rehabilitate damage from off-highway vehicles, access to about 20 percent of the monument has been temporarily closed to motorized use.  Public lands within this field office are near developed and expanding communities and are heavily used.  The lands are managed for multiple use and provide diverse recreational opportunities, mining, wildlife habitat, grazing, and wilderness, all overlaying a rich cultural past.  The field office oversees six wilderness areas, four Areas of Critical Environmental Concern, the Juan Bautista de Anza National Historic Trail and one property listed on the National Register of Historic Places.
