Project SHPO Number

When a project goes through state-level historic preservation review, the SHPO typically assigns a tracking or log number, and shpoNumber is where you record it. Storing it on the Project keeps your regulatory correspondence tied to the right investigation, which matters when you submit forms, respond to comments, or compile compliance reports. It is optional because not every project triggers SHPO review, but for those that do it is an important reference. Relic indexes this field, so you can look up a project directly by its SHPO number — useful when an agency contacts you about a case and only cites that number.
