Calvert County schedules July work session and July 28 public hearing after heated debate over data-center moratorium

The Calvert County Board of County Commissioners on June 16 set a timeline to consider a moratorium on data-center projects but stopped short of imposing an immediate pause, prompting pointed exchange between members and extensive public comment.

Commissioners voted to direct staff to hold an evening work session on July 7 to review draft ordinance language, environmental-study options and proposed text amendments, and to advertise a noticed public hearing for July 28 so the board can vote on an ordinance. Planning and zoning Director Jason Brinkley told commissioners a moratorium must be adopted by local ordinance, requires public notice (advertised twice with at least 14 days' notice) and should be supported by defensible language and study evidence.

The board’s decision followed a lengthy, at-times heated discussion over whether the county should immediately impose a pause on permitting and land transactions tied to data-center proposals or first obtain independent environmental, acoustical and cumulative-impact studies. Supporters insisted that outside studies and a formal moratorium are necessary to protect residents and the county’s natural resources; opponents cautioned that broad, long moratoria risk legal challenge unless the county builds a defensible record.

"We need the absolute best independent firm possible that says, ‘we've done this in our sleep,’" said Commissioner Hart, arguing that the county should hire specialists and buy time for a thorough analysis. Several speakers urged a two-year moratorium; staff and other commissioners noted that most Maryland jurisdictions that have enacted moratoria used shorter, 6–12 month pauses and that any duration should be defensible in court.

Public comment, which drew dozens of speakers both in person and online, was overwhelmingly in favor of an immediate moratorium. Residents cited heat-island modeling, diesel-generator emissions, noise and potential impacts on groundwater, schools and the Chesapeake Bay. Pam Warner of Indivisible Calvert County told the board: "The board should have directed staff today to cease work on text amendments, and to focus only on drafting a moratorium ordinance." Patrick Flaherty said the board’s recent conduct has "brought discredit and ill repute to Calvert County," and multiple commenters urged the board to follow the recommendations of its Environmental Commission.

Planning staff said they have engaged third-party engineering firms to scope required studies and expected to present timelines and cost estimates at the July 7 workshop. Director Brinkley recommended bringing draft ordinance language to that meeting so it can be included in the formal public-notice package ahead of the July 28 hearing.

The board’s July schedule leaves the projects currently under local review moving forward administratively until the board takes final action. Commissioners said the extra time should allow staff to assemble a legally defensible record if the board chooses to adopt a moratorium. The July 7 workshop and July 28 public hearing schedule were adopted by majority vote; no immediate moratorium ordinance was enacted at the June 16 meeting.
