Data Center Water Impact Assessment Tool

Prince George's County, Maryland

Data center water impact assessment — Brightseat Tech Park (820 MW proposed) and regional cumulative effects on WSSC Water / Potomac River basin.

Moratorium — Extended to Jun 30, 2026
17.7Mgallons/day, total
The full water footprint of the proposed 820 MW Brightseat data center, counting both cooling and the water used to generate its electricity. That is 6.4 billion gallons a year, about 5.5% of WSSC Water's entire system capacity from a single facility, or the equivalent of 62,382 households.
9.4M gal/day direct (cooling, Scope 1) + 8.3M gal/day indirect (power generation, Scope 2). Methodology §3.

  • Nov 2025 Task Force issues 460+ page final report with 14 recommendations
  • Jan 23, 2026 Executive Order No. 1-2026 extends hold through April 30, 2026
  • Feb 11, 2026 Pending data center bills' hearings canceled — Council to consider collectively
  • Mar 17, 2026 CB-19-2026 introduced (Oriadha, Blegay, Dernoga) — repeals the detailed-site-plan-review exemption, requiring Council site-plan review for all future data centers
  • Apr 23, 2026 County Executive Braveboy issues a second extension — the permit hold is pushed from April 30 to June 30, 2026 (the moratorium did not lapse)
  • Jun 30, 2026 Extended hold expires. CB-19-2026 remains pending with no recorded final vote. Either new rules take effect, the hold is extended again, or a regulatory gap opens.

Not in standard reporting. This figure does not appear in corporate sustainability reports, which count on-site (Scope 1) water only. Google, Microsoft, and AWS report on this basis, so power-generation water is not reflected in their "water positive" claims.

Pending Legislation (as of April 2026)

Four data center bills were introduced. All hearings were canceled or postponed as of February 11, 2026 — the Council intends to consider legislation collectively before the moratorium expires.

Update (May 2026): the active named vehicle is now CB-19-2026 (Oriadha, Blegay, Dernoga; introduced March 17, 2026), which repeals the detailed-site-plan-review exemption for qualified data centers. It remains pending — no recorded final vote — and the permit hold now runs through June 30, 2026. (The Diamondback, May 6, 2026)

Bill Sponsor Summary
LDR-001-2026 Most restrictive CM Jolene Ivey Data centers only by special exception in industrial zones. No by-right development.
LDR-016-2026 Moderate Chair Oriadha & CM Blegay Requires detailed site plans for all data center proposals.
LDR-021-2026 Process CM Adams-Stafford Transparency and process requirements: searchable database of pre-application neighborhood meetings.
LDR-028-2026 Less restrictive CM Blegay By-right in industrial zones; special exception in agricultural/rural zones (25+ acre parcels, distance requirements).

Community Benefits Agreement (CBA) Status

No legally binding CBAs have been executed with any data center developer in Prince George's County as of April 2026. The CBA framework remains an advisory recommendation from the Task Force report, not yet codified in legislation.

The Task Force's 14 recommendations included community benefits alongside special-use exceptions and overlay districts. Task Force Co-Chair Anthony Jones stated: "Data centers should be held to high energy efficiency standards, and data centers that locate in the county should also provide community benefits to the county." Dozens of residents at the January 27, 2026 Council briefing asked for workforce-development commitments and monitoring requirements for energy, water, and noise. (Citizen Portal)

A prior CBA precedent exists: MGM National Harbor executed a CBA with the county for casino development. (PG County CBA Summary). Separately, Brookings Institution (Jan 2026) published a report recommending CBAs for data centers, citing the PG County situation.

What Happened at April 30 — and What's Next

The moratorium did not lapse. On April 23, 2026, County Executive Braveboy issued a second executive order extending the permit hold from April 30 to June 30, 2026 — her first extension (EO 1-2026) had moved the original CR-98-2025 180-day hold to April 30. (The Diamondback, May 6, 2026)

That buys the Council roughly two more months to act on CB-19-2026, the ordinance to repeal the detailed-site-plan-review exemption for qualified data centers. As of late May 2026 the bill remains pending with no recorded final vote.

Three scenarios still apply at the June 30 deadline:

1. Legislation passes. CB-19-2026 (or a successor) takes effect and the hold is replaced by permanent site-plan-review rules.

2. Another extension. A third executive order buys more time but faces growing legal and political pressure from developers.

3. The hold lapses with no replacement. A regulatory gap opens and Brightseat Associates and others could resume applications under pre-moratorium rules — the framework that allowed Planning Board approval without Council review.

The county's structural budget deficit (reported in the range of $130M–$200M for FY2026, depending on source) keeps data center tax revenue in the conversation even among skeptics. (WJLA)
