Oak Park Completes Two-Day Emergency Response Exercise

Oak Park completed a two-day emergency-preparedness exercise that brought together local schools, municipal departments, hospitals, transit officials and neighboring communities to test how they would coordinate during a serious emergency.

The full-scale emergency-management exercise took place Monday, Aug. 3, 2026, at Oak Park and River Forest High School. A second exercise focused on reunification procedures was held Tuesday, Aug. 4, at the high school and Percy Julian Middle School.

The exercises tested established response protocols, interagency coordination and communication systems. They were conducted by Oak Park agencies and regional partners rather than in response to an actual emergency.

Schools and public agencies tested together

Oak Park police, fire, public health and public works departments participated in the exercises. The Village of Oak Park identified Oak Park and River Forest High School and Percy Julian Middle School as the two Oak Park-area school sites involved.

The regional participation included the River Forest and Forest Park police and fire departments, local school districts, Cook County, Rush Oak Park Hospital, Loyola University Medical Center and the Chicago Transit Authority.

That mix of participants reflects the practical demands of a large emergency. A response could require schools to account for students and staff, police and fire departments to manage immediate operations, public health officials to coordinate health-related needs, hospitals to prepare for patients, and transit agencies and neighboring communities to communicate across jurisdictional boundaries.

What the drills were designed to test

The Village of Oak Park said the exercise was intended to evaluate and strengthen emergency-response plans, coordination and communication systems. The Aug. 4 reunification exercise added a specific test of how schools and emergency partners would manage the process of bringing students and families together after a major disruption.

Reunification planning can involve more than identifying a location. It requires participating agencies and schools to use shared procedures, communicate information and coordinate movement among the affected sites. The packet does not provide operational details about the exercise design beyond its full-scale and reunification components.

The exercise took place over two days, Aug. 3-4, and involved two named school locations. Its local significance is therefore tied to preparedness: Oak Park and its partners had an opportunity to practice their plans in a coordinated setting instead of waiting to test those systems during a real crisis.

Findings have not been released

The official announcement identifies the participating agencies and the purpose of the exercises, but it does not disclose the simulated emergency scenario or post-exercise findings. It does not say that the drills uncovered failures or deficiencies.

No public after-action report was identified in the approved source material. As a result, the completed exercises show that the agencies conducted a coordinated preparedness test, but the available information does not establish whether any plans will be changed or what specific lessons participants recorded.

The next useful public update would be a summary of the exercise findings or an after-action report, if one is released. Until then, the confirmed development is the completion of the two-day test involving Oak Park schools, village departments and a broad group of regional emergency-response partners.
