MARYLAND COUNTY‑BY‑COUNTY VULNERABILITY ASSESSMENT
Which counties are ripe for a quiet‑phase data‑center deal — and why.
HIGH‑RISK COUNTIES (Likely Targets)
These counties have the perfect combination of power, land, weak zoning, and executive discretion.
1. Calvert County — EXTREMELY HIGH RISK
Why:
- Nuclear plant (Calvert Cliffs) = massive power availability
- Confirmed NDA already in place
- Commissioner system (centralized authority)
- Rural land near transmission lines
- Economic development staff already signaling interest
Likelihood of quiet‑phase deal: 10/10
2. Charles County — HIGH RISK
Why:
- Cheap land
- Transmission corridors
- Rapid growth + revenue pressure
- Zoning not fully updated for data centers
Likelihood: 9/10
3. St. Mary’s County — HIGH RISK
Why:
- Weak zoning
- Rural land
- Economic development incentives
- Proximity to Calvert grid infrastructure
Likelihood: 8/10
4. Caroline County — HIGH RISK
Why:
- Cheap land
- Fiber backbone running through the Shore
- Desperate for economic development
Likelihood: 8/10
5. Washington County — HIGH RISK
Why:
- Power infrastructure
- Industrial land
- Proximity to I‑70 corridor fiber
Likelihood: 7/10
6. Cecil County — HIGH RISK
Why:
- I‑95 corridor
- Cheap land compared to Harford
- Strong transmission lines
Likelihood: 7/10
MODERATE‑RISK COUNTIES
These counties could be targeted but would face more friction.
7. Frederick County — MODERATE
Why:
- Strong grid
- Large parcels
- But: highly organized residents, strong zoning
Likelihood: 5/10
8. Anne Arundel County — MODERATE
Why:
- Fiber + power
- But: expensive land, strong civic engagement
Likelihood: 4/10
LOW‑RISK COUNTIES
These counties are unlikely targets due to cost, politics, or zoning sophistication.
9. Howard County — LOW
Why:
- Expensive land
- Highly organized residents
- Strong zoning
- No economic desperation
- Developers know they’d get hammered
Likelihood: 2/10
10. Montgomery County — VERY LOW
Why:
- Extremely expensive land
- Aggressive environmental politics
- Strict zoning
- High‑capacity opposition
Likelihood: 1/10
III. THE MARYLAND TAKEAWAY
Yes — counties should be watching for this.
The combination of:
- NDAs
- quiet‑phase negotiations
- zoning rewrites
- sudden meetings
- and power‑grid coordination
is now the standard data‑center playbook.
Maryland is especially vulnerable because:
- It has a statewide tax incentive
- It has rural counties with commissioner systems
- It has major power infrastructure
- It has counties that don’t understand the industry yet
This is not a conspiracy — it’s a corporate strategy.



Hi Barry - would be very interested in any data points you have on this analysis relative to Harford County.
What is MACo providing to county leadership as education and impact tools or policy guidelines and what should residents be on the lookout for regarding public record on potential data center development activities?
