California mitigation credits
A monthly snapshot of California's mitigation banking market — wetland, stream, species credits — built on federal RIBITS bank, ledger, and service-area data.
California mitigation credit supply loosens across all types
California credit availability loosened across wetland, stream, and species markets over the trailing twelve months. Species credits dominate available supply, with a much larger inventory than wetland or stream credits. Releases outpaced withdrawals in each category, adding to available balances.
Wetland credits showed the tightest ratio of withdrawals to releases. Stream and species credits saw higher withdrawal activity but retained ample inventory. Overall conditions remained biased toward looser supply.
- All three credit types trended toward looser supply.
- Species credits concentrate the majority of available inventory.
- Releases exceeded withdrawals across every credit type.

How to buy mitigation credits in California
If your project impacts a regulated resource in California, you'll typically need to offset that impact by purchasing compensatory mitigation credits. Which bank you can buy from is determined by service area — a bank is generally approved to sell only to impacts inside its watershed (HUC), so geography comes first.
For federal Clean Water Act §404 impacts, wetland and stream credits are tracked in the U.S. Army Corps of Engineers' RIBITS system.
The practical steps: (1) confirm your impact type and quantity, (2) identify the HUC your impact falls in, (3) find banks whose service area covers that HUC with the right credit type available, and (4) contact the bank sponsor for a price and reservation. MitigationDesk collapses steps 2–4 into a single search.

How many mitigation banks serve California?
As of the latest snapshot, roughly 229 mitigation banks have service areas covering part of California, spanning every status including ILF programs and inactive banks. Of those, 148 are approved and active.
What types of mitigation credits are available in California?
California banks offer wetland, stream, and species credits. Each credit type trades on its own supply-and-demand curve and is never interchangeable with another — a stream credit can't offset a wetland impact.
Does California have species mitigation credits?
Yes. California has mitigation banks offering species credits. Availability is driven by service area, so which specific banks can serve a given project depends on the project's watershed (HUC).
Who regulates mitigation credits in California?
Mitigation credits in California (wetland, stream, and species) are tracked by the U.S. Army Corps of Engineers through RIBITS (the Regulatory In-lieu fee and Bank Information Tracking System), which records every bank's ledger and service area.
How much do mitigation credits cost in California?
Mitigation credit prices are not public and vary by credit type, local availability, and service area — a scarce credit type in a thinly-supplied watershed commands more than an abundant one. Prices come from the bank sponsor directly. MitigationDesk surfaces the sponsor and sales contact for every California bank so you can request a quote.
