USACE Divisions
USACE operates through nine regional divisions; eight run the domestic regulatory program that oversees compensatory mitigation banking, and those eight are tracked here. Division boundaries follow watersheds, not state lines — a bank's regulator is set by which basin it sits in, not by its state.

Nationally, a bank clears the regulator in about 10 months — the median from complete draft instrument to decision, pooled across every division.
Across 145 banks with a measurable regulator clock, the median is 299 days — half clear between 197 and 483 days. This clock is the regulator's own: draft instrument to decision, excluding the time an applicant spends revising. Where a division runs faster or slower than this figure is the whole of the comparison table below.

USACE divisions and districts — common questions
How many USACE divisions are there?
USACE operates through nine regional divisions. Eight of them run the domestic regulatory program that oversees mitigation banking — the eight tracked on this site. The ninth does not oversee the domestic compensatory-mitigation program, so it does not appear here.
How many USACE districts are there?
USACE has 44 districts, per the Corps' own unit-websites page. Not all 44 carry a domestic regulatory mission; the ones that oversee mitigation banking are the districts you'll find on each division's page here.
What is a USACE division?
A division is a regional command that groups several regulatory districts along watershed lines. The district — not the division — issues a bank's permit and runs its approval clock; the division is the level at which those districts are organized and compared. Each division's page here carries its own district breakdown.
Where do these numbers come from?
Approval timelines are from USACE ORM; credit supply and pending-bank counts from USACE RIBITS; permit demand from the USACE Regulatory Request System. All are public federal records, derived in git. District boundaries on the map are fetched from EPA's published USACE District Boundary layer when the page loads. Counts and medians only — no modeled averages, and district rows live on the division pages, not here.
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. Single-client banks are excluded from supply figures. Credit balances count only banks that can sell today — sold-out, suspended, terminated, withdrawn, closed-out and not-yet-approved banks are left out. 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. Approval timelines come from the USACE permit-processing record (ORM). We calculate the median from every bank’s milestone dates in the division. Full clock means from the first public notice of the prospectus to the final decision — it includes the applicant’s own time. Regulator clock means from the complete draft instrument being received to that same final decision — the part the Corps controls. A median is shown only where at least four banks have both milestone dates. In-lieu fee instruments are excluded throughout. Public notices come from the USACE Regulatory Request System (RRS). Notice text is the Corps’ own; the one-line summary beside it is an AI generated summary.
