Annual recurring
$8.9M
Personnel

Estimated one-time capital/setup costs are approximately $19.10M (major drivers: Site-95 expansion, DAS/sensor installation, catastrophic planning reserve). Recurring program costs are roughly $8.89M/year, driven primarily by embedded personnel wages, contingency reserves, and ongoing monitoring/response operations.

⚡ Cost Scenarios
📊 Baseline (baseline) $8.9M/yr
90.0% probability / year
Normal year with regular monitoring, embedded staffing, weekly rodent runs, GPR/sensor operations, and routine legal/cover/PR activity; no major incidents.
no major structural events regular weekly operations routine maintenance and cover activities
🚨 Minor Incident $9.1M/yr
8.0% probability / year +$250K vs baseline
Localized civilian exposure or small structural ejection requiring extra amnestics, PR/legal response, overtime, targeted repairs, and increased disposal activity.
civilian sighting requiring cohort amnesticisation small-scale ejection (SCP-4594-1) cleanup targeted PR/legal mitigation
🚨 Major Breach $13.9M/yr
1.9% probability / year +$5.0M vs baseline

📋 Confidence Notes
Analyst notes are detailed with line-item estimates and ranges, allowing a mid-confidence aggregate; however many items have wide ranges (incident-driven remediation, catastrophic interventions, borough coverage) and currency conversion introduces further variance. All GBP→USD conversions in this estimate use a conversion assumption of £1 = $1.25 and intermediate-range midpoints where ranges were given.
