Tribal Land Boundary Polygons, R6 and R9 U.S.-Mexico Border Region, 2021, U.S. Environmental Protection Agency

Metadata Updated: March 22, 2024

This polygon feature class contains the boundaries of tribes in the U.S. - Mexico Border region used by U.S. EPA Region 6 (R6) and U.S. EPA Region 9 (R9) for the Border 2020 Program.

R6 tribal boundaries were acquired from the R6 GIS Office (based on the 2010 US Census Bureau TIGER/Line file) and the Ysleta del Sur Pueblo GIS Department. R9 tribal boundaries were acquired from the R9 Technology and Data Solutions Center are are based on data from the Bureau of Indian Affairs (BIA) Pacific Region Office and the AZ/NV Bureau of Land Management (BLM) Surface Management office. Tribal layers for both regions were merged and clipped to the border region for use in the U.S. - Mexico Border Program Application.

These data support the U.S.-Mexico Border Program Map, which highlights the projects funded through the U.S.-Mexico Border Program (2013-2020) in both Region 9 and Region 6 of the U.S. EPA, including U.S. Federally recognized Tribal communities and states of Texas, New Mexico, Chihuahua, Nuevo Leon, Tamaulipas, Coahuila, California, Baja California, Sonora, and Arizona within 62 miles (100 kilometers) of the U.S.-Mexico Border. The projects stem from the Border 2020 framework that has five goals to reduce air pollution, improve access to clean water, promote materials and waste management, improve emergency preparedness, and enhance environmental stewardship, and fundamental strategies that includes children's health and environmental education and outreach.
