Standard Disaster Accounting Misses Earth9 Marine Infrastructure Losses
A Council working group has identified a systematic gap in how billion-dollar disaster costs are tallied for the Bay Area, finding that existing frameworks built on Earth-0 NOAA and NCEI models fail to capture losses to ferry terminals, docks, vessels, and expanded waterfront development. A revised accounting framework is under development.
The problem is definitional. Standard disaster-cost methodologies were built around road infrastructure, commercial real estate, and agricultural loss categories. On Earth9, the Bay Area's largest exposed assets are now marine and waterfront-facing, and they carry different storm surge and seismic risk profiles than the freeway and interchange assets they replaced. Until the accounting framework is updated, official loss figures for Bay Area disasters will be structurally understated.
