## Key facts

| Fact | Value |
| --- | --- |
| Practice area | [Planning & Environment](https://ailawframework.com/practice/planning-and-environment.md) |
| Human involvement | Red: Lawyer writes; AI may check, clarify or collect data |
| How AI is used | List the approvals the papers already name, the ordinance sections already cited, and the missing documents. Write no sentence of the advice letter. |
| What the lawyer must review | Advice on whether a project can proceed depends on the ordinance adopted under Government Code section 65850 and on any federal duty that actually applies, including a detailed statement under 42 USC section 4332 where the action is a major federal action significantly affecting the human environment. You write the letter. The tool does not. Opinion 512: a generated risk ranking is not your advice. Model Rule 1.6 covers the client plans in the file. |

## Checking plan

- What the AI does: List the approvals the papers already name, the ordinance sections already cited, and the missing documents. Write no sentence of the advice letter.
- Basis: Checked against the linked sources on 22 October 2026. Confirm the current instrument before reliance.

## Notes

- The letter is signed advice. No sentence of it is generated.
- Do not state a probability of approval. Nothing opened supports a figure.
