Norristown Municipal Council adopted Ordinance 26-04 in a unanimous 7-0 roll-call vote on August 18, 2026, after a public hearing. The ordinance establishes CONDITIONAL-USE ZONING for data centers in the Heavy Industrial (HI) district and imposes 14 mandatory submittal categories including energy-usage plans, water-usage and thermal-impact mitigation, pre- and post-construction noise studies with low-frequency sound analysis, air pollution and plume studies, an emergency-response plan, electronic-waste plan, and a decommissioning plan with posted financial security. Physical standards for larger facilities: 5-acre minimum parcel, 60-foot maximum building height, 250-foot setback from property lines, and 1,000-foot separation from residential and other sensitive uses. Norristown is the county seat of Montgomery County, Pennsylvania, and this entry sits inside an unusually dense southeastern Pennsylvania cluster. Pennsylvania also has the most aggressive state-level instrument in this dataset — Governor Shapiro's executive order conditioning state permit review on prior local approval and prohibiting data center non-disclosure agreements outright. Municipalities in the state are therefore drafting with more leverage and more information than most of their counterparts elsewhere.
Who is protected: Norristown residents in Montgomery County, Pennsylvania
Legal detail
Municipality of Norristown, Pa. (Montgomery County) — DATA CENTER ORDINANCE passed by Norristown Municipal Council, reported AUGUST 21, 2026, following public comment from area residents. CHARACTERISATION: the unanimous action is described as outlining STRINGENT CRITERIA for proposed data centers. Council members David McMahon, Jasmine Griffen and Will McCoy are identified as present. INSTRUMENT CLASS: a standards ordinance rather than a moratorium. SOUTHEASTERN PENNSYLVANIA CLUSTER, which is the context that gives this entry weight: Falls Township PA curative amendment on data centers (2026) (Bucks County \u2014 declaring its own ordinance substantively invalid to control the curative remedy and foreclose developer validity challenges), MORRISVILLE BOROUGH (six-month waiting period, unindexed lead), MONTGOMERY TOWNSHIP (unanimous zoning amendment with extensive data center regulations, queued), WHITEMARSH TOWNSHIP (moving to advertise, with WEST CONSHOHOCKEN and UPPER MERION having previously adopted similar ordinances \u2014 all unindexed leads), and Ligonier Township PA data center zoning regulations (2026) in Westmoreland County. STATE-LEVEL LEVERAGE: Pennsylvania EO 2026-05 data center restrictions (2026) gates DEP permit review on a developer having ALREADY OBTAINED LOCAL APPROVAL and on a legally binding GRID commitment, removes AI data centers from Fast Track permitting, and PROHIBITS DATA CENTER NON-DISCLOSURE AGREEMENTS. Pennsylvania municipalities therefore negotiate with information and sequencing advantages that municipalities in most other states in this dataset lack \u2014 which is the likely explanation for the density and sophistication of the local instruments emerging there. THE SPECIFIC CRITERIA ADOPTED BY NORRISTOWN ARE NOT STATED in the located source and are the material gap; this entry should not be cited for particular requirements.
