Read your city's drainage code
Timebox: one hour, no digging. Output: three clauses with citations, in your own words, with the adoption date. Most residential drainage work lives or dies on those three: how close to the foundation, where the water may go, and whether your project trips a permit. Everything else on this desk bows to them.

Steps
- Find the document. Search “[your city] stormwater code” or “drainage ordinance.” Municipal codes are public; most cities publish them online with the current adoption date. County and HOA documents sit in a second and third pile — pull them later, don't ignore them.
- Open the stormwater chapter. Look for titles like “Stormwater Management,” “Drainage,” or “Site Grading.” Note the chapter number and adopt date. A 2019 chapter with 2024 amendments matters: read the amendments.
- Pull clause one: setback. The minimum distance between any drainage feature and a foundation. Ten feet is the common residential number on this desk's pages; your city's may differ, and your city's wins.
- Pull clause two: discharge. Where water may legally go — to the street, to a storm drain, across a property line. This is the clause that turns a neighbor dispute into a citation. Copy it out.
- Pull clause three: permit triggers. What makes a project need a permit — usually disturbed area, added impervious surface, or discharge volume. Your catchment number is the test.
- Save the citations. Chapter, section, adopt date, link, and the sentence in your own words. When the inspector calls, you will not be quoting a blog.

Where people stop
- Reading a summary instead of the code. Contractor blogs paraphrase, and paraphrase ages. The citation is the thing that does not age — until it does, and the adopt date tells you when.
- Skipping the HOA pile. A covenant can be stricter than the city. Not law, still binding on you.
- Stopping at “it's my yard.” Your yard is a drainage district's smallest member. The discharge clause exists because someone upstream of you thought the same thing once.
Where to go next
- Diagnose standing water — the check that decides what fix the code must bless.
- Swale — the setback number in its natural habitat.
- Method — how the desk treats code figures everywhere.
