CHICAGO (CBS) — The June 30 hailstorm that destroyed a portion of the Garfield Park Conservatory has prompted a fundraising drive to sustain the institution until insurance kicks in.

As WBBM Newsradio 780’s Mary Frances Bragiel reports, the storm hit late in the evening, and when it was over, more than half the glass panes in the historic Fern Room, Show House, and 10 greenhouses were broken.

Chicago Park District director of conservatories Mary Eysenbach says the cleanup has been difficult, and is not complete just yet.

In all, 23,000 glass panes were destroyed in the storm, and much of the conservatory remains closed. Only areas such as the Palm Room and Horticulture Hall remain open because they had been updated relatively recently with laminated glass that was not broken by the hail storm.

Until the damage assessment is finished, officials say insurance will not cover the devastation.
