Where we're working
A corpus is built for one jurisdiction at a time, in the order a facility actually gets built, and it opens where a decision is being made rather than where the news is loudest.
Where the rules are being written
We started with Hillsboro and Washington County, Oregon. The register now reaches 51 states, plus tribal nations, utilities and federal rules, and it grows every week as cities, counties and utilities act. Every entry names the document it came from and says whether we read it in the original.
As of October 8, 2026
Oregon
Hillsboro and Washington County. Land use, enterprise zone abatement, rate allocation and water, with three findings checked against the City's own records.
3 FINDINGS PUBLISHEDThe register
Every provision in one searchable list: moratoria, zoning, tariffs, incentives, water and interconnection rules. Filter by state or mechanism, or link to a single entry.
SEARCH THE REGISTERThe map
Every state with entries in the register, on one map, with counts that update when the register does.
SEE EVERY STATEMoratoria
Every local pause in the register on one list, sorted by when it ends, with what triggers it and the document behind it.
SEE WHAT EXPIRES NEXTAfter the pause
What twelve cities and counties adopted once their pauses ended: setbacks, noise, water, power and generators, side by side.
COMPARE THE RULES- 01Queued. We've named it as a comparator and haven't read anything yet.
- 02Corpus open. We're reading the primary instruments and marking them. Most of a corpus at this stage is still unread, and it says so — that means nobody has looked yet, not that nothing's there.
- 03Findings published. Specific claims graded against named records, or measurements nobody had made. Free either way, whether or not somebody paid for the underlying work.
- 04Engaged. A client is paying for private work here. A public body is named on the funding disclosure the day it starts; a private client is counted by type. The findings don't change either way.
Why the comparison matters
A jurisdiction writing a data center ordinance is rarely asking whether to regulate. It is asking what has already been tried, by whom, and what the instrument actually did once adopted. That answer exists only in the codes themselves.
Across the jurisdictions read so far, structurally different mechanisms are being used for the same problems: prohibition and exception structures, special permits tied to utility commitments, definitional rules, physical thresholds, operating restrictions, and tariff entry gates.
As of October 8, 2026, the register holds 550 provisions across 297 jurisdictions in 51 states, with primary instruments at different stages of review. Where an instrument has not been read in original, the corpus says so rather than implying otherwise.
Coverage is not a subscription and a corpus is not a product you buy off a shelf. If a decision is moving in your jurisdiction and no neutral record exists, write and say so. If we take it on as self-funded work, it is published as self-funded. If you engage us as a public body, that appears on the funding disclosure before the work starts.
