Ask about a permit requirement, a threshold, a sizing step, or a design choice. Every answer is
drawn only from the loaded documents and cites the section and printed page it came from. Where
the documents are silent the assistant says so — it does not fill the gap.

This is a reading aid, not a determination. The assistant can only tell you what the loaded
documents say: the Construction General Permit (Order 2022-0057-DWQ, without its Fact Sheet), MRP 3
(Order R2-2022-0018 as amended by R2-2023-0019, Provision C.3 and C.6 only), the Contra Costa
C.3 Guidebook (Revised 9th Edition, June 2025, without its appendices A, B, E, F), and the Alameda
C.3 Stormwater Technical Guidance (Version 8.4, June 2026, chapters only). San Mateo, Santa Clara and
Solano guidance, Phase II MS4 requirements, the Fact Sheets, and municipal ordinances are not loaded.
Worked examples are illustrations, not designs. They are computed from the inputs you type and the cited tables, and they carry no professional judgement. Confirm every number against the cited page before it goes on a plan or into SMARTS, and refer Risk Level, jurisdictional (WOTUS), and interpretive questions to the department's QSD.
