Norristown Municipal Council passes data center ordinance
Norristown Municipal Council unanimously adopted a data center ordinance on August 21, 2026, establishing zoning regulations for data center facilities in the municipality's 41-acre heavy industrial district near SEPTA's Norristown Transportation Center and the Schuylkill River. The ordinance includes 14 categories of development requirements, addressing environmental concerns, utility infrastructure costs, backup power generation, air pollution, decommissioning plans, and plume studies. Council members David McMahon and Jasmine Griffen spearheaded the initiative to establish strict guidelines proactively, following data center proposal activity across the region and concerns about nuisance impacts. The measure updates the existing zoning code to define and regulate data center uses under conditional use provisions, ensuring compliance with Pennsylvania state law which requires municipalities to provide for legal land uses within their jurisdiction.

The approval enables construction of a liquefied natural gas storage tank and Bloom Energy fuel cells to generate the facility's power. Residents mounted sustained opposition over six hours of hearing, citing safety concerns about the LNG tank, carbon emissions of over 2 billion pounds annually, and water consumption of 8 million gallons yearly, but the board found the project compliant with local zoning and voted to approve it.

Allentown City Council tightens data center zoning ordinance after public backlash
Allentown City Council voted unanimously on Wednesday, August 7, 2026 to amend its June 2026 data center zoning ordinance with stricter requirements. The amendments reduce permitted industrial zones for data centers from two to one, increase setbacks from homes, schools and daycares from 200 feet to 500 feet, require stricter noise studies, mandate decommissioning plans, and require developers to hold public informational meetings before formal approval. The changes came after residents and anti-data center activists argued the original ordinance did not adequately protect communities from facility impacts including noise, energy costs and water pollution.
