Why does AirMap say no fly zone

[szymczaksteve]

AirMap says no fly zone at my house due to park.
The actually forest is a a block away or so and it's not a national park or any such sorts

Maybe a local rule (that's a County Forest Preserve just to the west), but there are no FAA restrictions on flying there. That location is underneath 700 ft AGL Class E, 1900 ft MSL Class C (KMDW), and 3600 ft MSL Class B (KORD). At the surface it is Class G and not within 5 miles of an airport.
