It is cancelled, since October 20, 2026. Developer Brian O'Neill sued Upper Merion Township Board of Supervisors over its rejection last month of his proposed 4.6 million square foot data center campus (reported September 18, 2026).

How to read this page. Every fact links to the source it rests on; a number in brackets is its place in the source list. A figure no source gives reads Not disclosed, and nothing is estimated. Where sources give different figures, each is shown with who gave it, and another source's figure never stands in for the record's own. Entries are added and never overwritten; corrections are listed under What happened.
Each figure as its source gave it. The number in brackets is its place in the source list.

A blank value cell means not disclosed by any source on file; a blank basis cell means the source gave the figure without saying on what basis.
The developer's figure is what the company said; what a permit allows is the ceiling a permit sets; measured means observed. Water is in gallons a day or a year, whichever the source stated; a tax claim given as a range shows both ends, each linked to the source that gave it.
The record adds each the day a source gives it. Why these documents.
