Federal officials are moving forward with plans to construct three new Border Patrol stations and two additional checkpoints across Arizona, marking a significant expansion of border security infrastructure in the state. The projects, each expected to cost over $100 million, are designed to accommodate a combined total of approximately 1,000 Border Patrol personnel.

The initiative reflects a broader federal effort to bolster border enforcement capabilities in response to ongoing challenges related to unauthorized crossings and migration management along the U.S.-Mexico border. The U.S. Customs and Border Protection (CBP) agency confirmed the planned locations for the new stations: Three Points, Casa Grande, and the Sonoita-Elgin area. Funding for these projects is being provided through the 2025 federal reconciliation law, which allocated $5 billion nationwide for CBP facilities and checkpoints. According to CBP officials, the Arizona projects are currently in the early stages of planning and development.
Locations and Project Details
At Three Points, CBP is proposing a new station designed to accommodate 500 agents. The agency anticipates soliciting bids for the project by September 25, with a contract award expected between October and December. The planned facility would be situated on an 87-acre site, located about four miles east of the existing station. In a letter sent to Pima County in August, CBP specialist John Petrilla explained that the new station aims to support additional agents, with the goal of enhancing border security within the Tucson Area of Responsibility. The ultimate objective, Petrilla wrote, is to increase the probability of apprehending individuals who have entered the United States illegally.
The proposed Casa Grande facility is expected to house 300 agents and support staff. While the specific address has not yet been disclosed, the project is anticipated to follow a similar cost and timeline as the Three Points station. Meanwhile, the Sonoita-Elgin station is planned to accommodate 200 agents. County officials have indicated that the preferred site for this facility is an undeveloped 40-acre parcel located about four miles southeast of the Sonoita crossroads, near Elgin Elementary School. An alternative site along State Routes 82 and 83 is also under consideration.
Each of the three projects is projected to exceed $100 million in construction and development costs. The estimated completion date for all facilities is September 2029. CBP has clarified that the stated capacities for each station refer to the size and design of the facilities, rather than a confirmed increase in the number of agents assigned to Arizona at this time.
Funding and Legislative Background
The funding for these projects comes from the 2025 federal reconciliation law, known as the One Big Beautiful Bill Act. This legislation appropriated $5 billion for CBP infrastructure projects across the country. Section 90002(a)(4) of the law specifically authorizes expenditures for leasing, acquiring, constructing, designing, or improving CBP facilities and checkpoints. CBP has stated that the Arizona station and checkpoint projects will be financed through this allocation, as part of the agency’s broader efforts to modernize and expand its operational footprint along the border.
Local Input and Environmental Review
As part of the planning process, CBP has requested input from local officials and stakeholders regarding environmental assessments for the proposed sites. In Pima County, the agency sent a letter seeking feedback on the environmental impact of the Three Points location. In Santa Cruz County, officials have noted that the preferred site for the Sonoita-Elgin station is in close proximity to Elgin Elementary School, raising potential concerns about the station’s location relative to community resources and sensitive areas. An alternative site is being considered to address these concerns.
"The purpose of the new BPS is to accommodate the addition of new agents and personnel intended to enhance border security within the U.S. Border Patrol Tucson Area of Responsibility, with an ultimate objective of increasing the probability of apprehension of those that have entered into the U.S. illegally."

CBP has indicated that environmental and site assessments are ongoing, and that local officials and community members will have opportunities to provide input as the process moves forward. The agency has not yet publicly addressed specific concerns related to the proximity of the new stations to schools or other community sites, but such issues are expected to be part of the review and consultation process.
Broader Border Security Context
The planned expansion of Border Patrol infrastructure in Arizona comes at a time when the state continues to be a focal point in national discussions over border enforcement and migration policy. The proposed stations and checkpoints represent a substantial federal investment in physical infrastructure, signaling a commitment to strengthening operational capabilities along the border. However, CBP has emphasized that the planned capacities of the new facilities do not necessarily indicate an immediate increase in the number of agents deployed to Arizona.
As planning and environmental review processes advance, local officials, community members, and other stakeholders are expected to play a role in shaping the final details of the projects. The outcome of these consultations will likely influence the timeline and scope of construction, as well as the integration of the new stations and checkpoints into the broader border security strategy for the region.
