Emergency Preparedness
The City of Warrenville has in place a comprehensive Emergency Operations Plan. This plan is defined as an “All Hazards” type plan, and gives guidance to the various departments and members of the Crisis Management Team. The hazards defined in the scope of the plan cover all man-made and natural hazards including terrorism. Crisis Management Team members are familiar with their duties and responsibilities, as indicated in the Emergency Operations Plan.

Crisis Management Team
In the event of the threat condition being elevated to Threat Condition Orange or Threat Condition Red, the Homeland Security Office will provide additional information pertinent to the current situation. The Warrenville Police Department, will rapidly notify members of the Crisis Management Team of any changes in threat conditions. The Crisis Management Team will evaluate the available information and determine what actions the City will initiate. Du-Comm, the City’s 9-1-1 dispatch center, will follow the procedures outlined in the Homeland Security section of their Procedure Manual. These actions will ensure proper notification of city officials during periods when Police Department personnel are not available.

Threat Conditions

All City and Fire Protection District facilities will be secured and locked when not occupied. All vehicles and emergency equipment will be kept in a state of operational readiness. All vehicles, when parked unattended, will be locked at all times. Overnight parking of vehicles will be in a secure lot. All personnel will be alert to suspicious activities and articles, and will report them to the proper authorities. Mail will be handled in a routine manner with common sense being applied in handling mail which appears to be leaking, has a bulging appearance, or has other circumstances which cause suspicion.

Current safeguards in use are adequate to protect the city’s information systems. A plan for the protection of City-owned structures has been developed and a list of critical infrastructure facilities within the City has been prepared. Outdoor warning sirens and the DuPage County Emergency Radio Net are tested at regular intervals.

National Incident Management System (NIMS)
In October 2005, homeland security presidential directives established a single comprehensive national incident management system (NIMS). The NIMS is a system that improves response operations through the use of the incident command system (ICS) and other standard procedures and preparedness measures. It also promotes development of multi-jurisdictional, statewide and interstate regional mechanisms for coordinating incident management and obtaining assistance during large-scale or complex incidents.

Since that time, the federal government has disseminated the NIMS compliance requirements metrics to all state and local jurisdictions. Part of the compliance measurement was to have all state and local jurisdictions self-certify their NIMS compliance by completing a NIMS certification form. In Warrenville, the Emergency Management Agency (EMA), the Police Department, and the Fire Protection District work together to meet the NIMS requirements.

Resident Preparedness
Terrorist attacks around the world have left residents concerned, asking about the City’s preparedness protocols and wondering what they can do to help. While Warrenville Police, Fire and EMA are regularly training and educating themselves on the latest protocols to address a terrorist threat or situation, how can residents know what to do? The U.S. Department of Homeland Security (DHS) states that the greatest tool citizens have against terrorism is to be aware and report any suspicious activity. To help raise public awareness, in DHS launched the If You See Something, Say Something campaign in conjunction with the U.S. Department of Justice's Nationwide Suspicious Activity Reporting Initiative (NSI).
