Definitions are written for reading a local record, not for selling a product.

What to verify locally: Use the glossary as a companion to the project and policy pages.

Plain-English glossary

Use original public records whenever possible. A developer statement can explain an intent; an approval, permit, or utility filing is where enforceable details are more likely to appear.

Terms in context

Record the date, document title, agency, page number, and project address. That turns a claim into something another reader can check.

Evidence standard: this guide avoids treating a proposal as a completed project, and avoids treating a missing record as proof that no impact exists.
