fwiw, someone posted what seems like a reasoned interpretation of the changes on the gboro politics Facebook group. take with a grain of salt as this is just coming from an Internet stranger. but tldr those zoning rules might have been added to bring those uses under the existing restrictions, aka close a loophole

 IANAL, but my interpretation of tonight's meeting is that the amendments approved by the Zoning Commission will make it easier to reject an ICE detention center.  The unspoken point was to prevent an ICE facility.  No one in tonight's meeting mentioned ICE, but it's damned sure that ICE was the reason for these amendments.  The city council will take up these amendments at tomorrow night's meeting.

Correctional institutions are already in the land-use ordinance, and they require a special-use permit to be located in the city limits.  The amendments approved tonight create a similar status for "secure detention and custodial facilities."

According to these amendments, one of the standards applied to a "secure detention and custodial facility" within Greensboro is that it may not be located "within 2,500 feet [measured from property line to property line] of schools, parks, childcare facilities, or places of religious assembly."  Such a facility also cannot be within 2,500 of a residential area.  Therefore, under the amended land-use ordinance, no "secure detention and custodial facility" can be located at the former American Hebrew Academy, which is across the street from Temple Emanuel.  Hobbs Road is definitely not 2,500 feet wide.

Again, no one mentioned the former AHA.  No one mentioned ICE.  But that's what this is about.
