East Whiteland Sentinel/Green Fig Data Center

East Whiteland Township, Chester County

A 1.5-million-square-foot, two-building data center on the former Foote Mineral Superfund site off Swedesford Road, approved in 2024, stopped twice by the township in 2026, and now waiting on foundation permits after Aqua agreed to supply up to 2.8 million gallons of water a day.

Approved Superfund-site data center has its water deal and waits on permits

The number that mattersA 2024 letter from Aqua, released through a Right-to-Know request in 2026, said: "Unfortunately, Aqua does not have the capacity to meet the peak demand … as requested." The water agreement signed in October 2026 has the developer paying to upsize mains and build a pump station.
Developer
Sentinel Data Centers (CEO Josh Rabina) and Green Fig Land LLC (Charles Lyddane), applying as Sentinel Green Fig LLC. Fifteenfortyseven Critical Systems Realty of Matawan, N.J., was Green Fig's earlier partner. Attorney Lou Colagreco represents the developers.
Tenant
No tenant has been publicly named.
Current stage
The project is approved and in early site work, and since the developers dropped their cooling-change request, the township expects them to build the approved 2024 plan. Foundation permits for both buildings and a 140-foot utility monopole, filed September 25, were still under review on the township's October 1 log, and the township said October 6, after Aqua's water agreement took effect on October 2, that it hadn't issued any more permits. On October 20, 2026 the resident group East Whiteland United sent the township, its supervisors and the developers a notice of intent to sue, and no suit had been filed as of October 22. A November 3 ballot question asks whether to expand the board to five supervisors.
Decision body
East Whiteland Township Board of Supervisors (land development approvals) and Zoning Hearing Board (2018 and 2021 variances); township staff issue building permits
Top issues
scale of the built footprint; legacy site contamination; water use; noise and continuous operation; backup generation and air emissions
Key opponents
East Whiteland United, which hired attorney Philip S. Rosenzweig in October 2026; Save East Whiteland; Food & Water Watch Pennsylvania (Ginny Marcille-Kerslake); residents whose land-use appeals were quashed in June 2026
Key supporters
No organized supporters have been reported. Some residents cited jobs and economic benefits at a March 2026 Planning Commission meeting (FOX 29). The developers say the 2018 and 2021 zoning approvals give them the right to build.

How we got here

The Zoning Hearing Board approved a data center use on the site in a decision dated February 26, 2018, and expanded it to an approximately 74-acre campus on November 16, 2021. Fifteenfortyseven Critical Systems Realty announced its partnership with Green Fig on August 30, 2022. The supervisors granted preliminary land development approval June 12, 2024 and final approval August 14, 2024 for about 1.5 million square feet. The plan was recorded March 31, 2026. A bid to enlarge the buildings to more than 1.6 million square feet and switch to waterless chillers went before the Planning Commission from January to March 2026; the developers offered an 887,000-square-foot version on April 14 and withdrew the amended plan in early May, returning to the 2024 plan. A judge quashed residents' appeals in June 2026 as untimely. The township stopped earth-moving in early July, let work resume July 29 under an erosion and sediment permit with Superfund conditions, and issued a second stop-work order August 26 pending water service. The board adopted Ordinance 385-2026 on September 24, which doesn't apply to this approved project. Aqua's water agreement took effect October 2, and on October 14 the board hired Ceisler Media at about $6,800 a month.

Update, October 26, 2026. On October 20, 2026 East Whiteland United, a resident group represented by attorney Philip S. Rosenzweig, sent East Whiteland Township, its three supervisors, Green Fig and Sentinel Data Centers an eight-page notice of intent to sue, saying it would go to court if its concerns weren't addressed immediately and substantially. The notice cites Aqua's earlier letter saying it couldn't meet the project's water needs, new permit applications that the group says would change the approved design, including dropping 20-foot basements from two buildings, and an environmental impact assessment it calls incomplete. Separately, the Public Utility Commission on October 1 denied a resident's request to reconsider its refusal to grant emergency relief against PECO's 150-megawatt line tap serving the site, and the resident filed a new petition for reconsideration on October 16.

3 MGD water demand projected.

Water

High

Aqua's 20-year agreement allows 500 gallons a minute until new mains and a pump station are built, then up to 2.8 million gallons a day at no more than 1,950 gallons a minute, with the developer paying the construction cost and posting a $25 million letter of credit.

Noise and vibration

Medium

The approved 2024 plan requires sound walls about 40 feet tall around the ground-mounted cooling equipment, decibel limits, and post-construction noise studies and monitoring, according to the township's approvals matrix.

Public safety

Medium

EPA says the capped Superfund area isn't part of the construction, but its September 2024 five-year review found more information was needed about the extent of groundwater contamination, and EPA rescinded the site's 'ready for anticipated use' designation that month. A 2017 covenant bars disturbing the cap.

Energy costs and the grid

Medium

PECO said in 2023 it could serve 290 MW via two 230 kV lines, with the first 150 MW tap estimated at $3.9 million and secured by a developer letter of credit, and said the second line would need significant work at Planebrook substation.

The approved plan includes two 150-foot microwave towers and two buildings about 45 feet tall, each with a footprint of about 250,000 square feet.

Traffic

Low

The approved plan requires left-turn lanes on Swedesford Road in both directions; a traffic signal at the entrance was found not warranted.

Coverage of this project

Sources

Know your rights

In Pennsylvania, the local zoning ordinance sets the route. A conditional use is decided by the elected governing body (supervisors, commissioners or council). A special exception or variance, and an appeal of a zoning officer’s decision, go to the Zoning Hearing Board. Each is a public hearing on a record: affected neighbors can ask for party status, cross-examine witnesses, and appeal. Municipalities can also adopt 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 press your municipality for a real ordinance. Pennsylvania municipalities cannot simply freeze applications, but a curative amendment under the Planning Code gives them a defined window to fix a defective ordinance.
