Coverage of this project

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.

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.
