Metal Detecting

131.06: Preservation of Property and Natural Features, reads as follows: "No person shall injure, deface, disturb or befoul any part of the park district, nor any building, sign, equipment or other property found therein. No person shall remove, injure, or destroy any trees, shrubs, wildflowers or other plants, animals, fossils or minerals within the park district."

Areas restricted from metal detector use are park district golf courses, areas designated for horticultural use, athletic fields, areas closed to the public, historic sites such as Shaker or Native American cultural sites, conservation areas, state dedicated nature preserves, designated wildlife sanctuaries, natural areas or such areas where damage from probing may incur maintenance problems. This would essentially restrict activities to mowed public use areas that do not qualify in any of the categories above.

Tools used for probing must be similar to a screwdriver or a digging trowel, with a blade length of no more than seven (7) inches, and a width of no more than two (2) inches.

Any area disturbed must be returned to its natural state.

Any cultural artifacts found on Great Parks' property must be turned into the park district.
