Know your rights
In Pennsylvania, a data center on industrial land usually needs a special exception or conditional use, decided by a local Zoning Hearing Board after a public, quasi-judicial hearing. Neighbors can request party status, cross-examine witnesses, and build an evidentiary record. Municipalities can also write data-center ordinances with enforceable standards.
Know your rights →Take action
Organized community opposition is the single most effective check on these projects in Pennsylvania. Show up to hearings, submit comment when it is taken, support legal and expert-witness costs, and ask your municipality for a moratorium and a real ordinance.
