About the data on this page
Bank details, status and credit balances are mirrored from the USACE RIBITS registry, the federal public record for mitigation banks. Credit classes offset different resources and are never added together. Totals across many banks are rounded to whole credits — a single bank’s own balance never is. What we call a “credit sale” is a credit withdrawal — the entry written in the federal credit ledger when credits are committed to a permit. At commercial banks a withdrawal generally represents a sale; at a single-client bank it offsets the sponsor’s own project. The figures count ledger transactions, not distinct purchases — one purchase may produce several withdrawals — and we count entries rather than credits moved, because credit classes are different units and cannot be added together. Each bar in a sales chart counts the credit sales recorded in that calendar year — withdrawals from the federal ledger, not quantities of credits. The final bar is the year in progress and is shown in a different color. No bars means no sales in those years.
The operator grouping is ours, not from RIBITS. The federal registry records a sponsor for each bank but lists no parent company. We identify operators by matching sponsor names and contact details across bank records, reviewed by hand. We only display operators with at least five banks.
“Recent sales” covers the last twelve months. A map of pins shows where banks and sites are, not where they can sell. Service areas are wider than the pin and are decided by the Corps — open a bank, or run a location search, to see the area it actually covers. The map on this page is drawn live from the EPA NEPAssist RIBITS MapServer when you load it.
