Limerick looks to make its data center zoning more restrictive
Limerick's Board of Supervisors unanimously voted to advertise an updated zoning ordinance for data centers, introducing more restrictive provisions for future developments. These changes aim to protect the public regarding noise, setbacks, water usage, and electrical rates. However, the new ordinance will not apply to two hyper-scale data center proposals already filed in the township.
The Limerick Board of Supervisors in Pennsylvania has unanimously voted to advertise a significantly updated zoning ordinance for data centers, aiming to introduce more stringent protections for the public. The proposed changes, which were informed by zoning in Loudoun County, Virginia, and a model ordinance from Montgomery County, include an increase in required setbacks from residential properties to 1,000 feet, a reduction in maximum building height from 129 to 80 feet, and new requirements for screening rooftop equipment.
The revised ordinance also addresses environmental and infrastructure concerns, mandating "closed loop" cooling systems to reduce water usage, requiring drought response plans, and instituting a "rate impact standard" to prevent data centers from affecting residential electricity rates. Additionally, it introduces lower decibel limits for noise, requires annual noise studies, and demands de-commissioning plans with a fund for demolition and site restoration. These comprehensive updates are not expected to apply to two hyper-scale data center proposals already submitted in Limerick, one of which has received a recommendation for approval with 18 conditions from the planning commission.
The proposed changes will now undergo review by county and township planning commissions, followed by a public hearing, with potential adoption not expected before July or August. Supervisor Patrick Morroney suggested even more stringent setbacks, but Township Solicitor Rebecca Weiser cautioned against overly restrictive measures that could invite legal challenges.
