Thor Guard: Lightning Prediction System

The Thor Guard system operates at the Commissioners Park.  This system measures the potential for lightning in the air and may alarm before any lightning strikes or can be seen.  

When the system detects the possibility of lightning the alarm sounds and strobes are activated.  The warning siren sounds for 15 second, and yellow strobe light flashes continuously.  The yellow strobe light continues to flash with no siren until the threatening conditions pass.

When the threat has passed the system sounds three blasts of the siren and strobe light turns off.  This is the all-clear signal. The potential for lightning has passed and all activities may resume.

While this system provides warnings after lighting has been sighted please do not fail to seek shelter if inclement weather is present.  If it is the opinion of the Park staff, teacher, coach, referee, or the general public that the weather situation is not safe, do not wait for horns to activate – CLEAR THE AREA! Take shelter in your vehicles anytime lightning is seen, or thunder is heard.

The system operates from Spring through the Fall, 24 hours per day.  The sirens are silenced from 11:00 PM until 700 AM, but the strobe lights continue to work during the silenced period.

Strike Guard:  Lightning Detection System

Naperville District has installed the STRIKE GUARD Lightning detection systems at the following locations: Nike Sports Complex, Centennial Park and Beach, Knoch Park, Frontier Park, DuPage Sports Complex and Springbrook and Naperbrook Golf Clubs.

This sophisticated computer system provides warning when dangerous conditions are detected. The system consists of sensors that measure lightning strikes in an 8-10 mile radius.  When conditions indicate that lightning has occurred, a signal is sent to an alarm horn. The signal provides an 8- to-12 minute warning that allows one to clear the area and seek shelter.  It is recommended that when the warning system is activated (15-second horn blast and strobe light flash), the park sites affected be cleared and activities not be resumed until the all-clear signal is given (3 short horn blasts and a cessation of the strobe light). These alarm tones are distinctly different from any current public alarm tones. It is recommended that park patrons and staff immediately seek shelter in their vehicles. If such shelter is unavailable, patrons should avoid areas that are higher than the surrounding landscapes, not to use a tree for shelter, and keep away from metal objects such as bicycles, golf carts, umbrellas, etc.

While this system provides warnings after lighting has been sighted please do not fail to seek shelter if inclement weather is present.  If it is the opinion of the Park staff, teacher, coach, referee, or the general public that the weather situation is not safe, do not wait for horns to activate – CLEAR THE AREA! Take shelter in your vehicles anytime lightning is seen, or thunder is heard.

The system operates from Spring through the Fall, 24 hours per day.  The sirens are silenced from 11:00 PM until 700 AM, but the strobe lights continue to work during the silenced period.

On Wednesday, Nov. 2, 2011 Naperville Park District officials heard the good news for which they have been waiting for many months: the District has achieved national accreditation through the National Recreation and Parks Association (NRPA).

The decision was announced at the NRPA national conference in Atlanta following a formal hearing before the Commission for Accreditation of Park and Recreation Agencies (CAPRA).

Naperville is only the second park district in Illinois to earn this distinction and the 104th nationally accredited agency in the nation; there are more than 10,000 recreation agencies in the United States. The Commission for Accreditation of Park and Recreation Agencies accredits a handful of park agencies each year that have completed a multi-step process involving a self-review by the agency, a site visit, and an evaluation and formal report by the Commission.

“We are extremely proud to bring this honor to Naperville,” said Park District Executive Director Ray McGury. “It’s an affirmation of our high standards and also an encouragement to continue bringing high quality recreation and parks experiences to our community.”

The Park District’s accreditation process began approximately one year ago and included an extensive self-evaluation by staff and a 5-day visit from CAPRA reviewers this past July. Maintaining the accreditation requires annual reports and 5- and 10-year reviews.

Park District staff members noted that the CAPRA process has helped them see the big picture, focus on long term goals and plans, review plans more regularly, organize documents so that they are accessible and useable, and collaborate more effectively with other departments and outside organizations.
