This is a reference list, not advice. Notice periods, thresholds, fees and forms change without warning, and a requirement in one county is not the requirement in the next one. Read the authority’s own page before you act on anything here, and treat this page as the fastest way to find that page rather than a substitute for it.

Why this list exists

Knowing which door to knock on is half the job.

Checkered Flag Excavation was founded in 2000 and works out of De Soto and Festus, Missouri. It holds Missouri septic installer and inspector licences, the St. Louis County Master Drainlayer licence, and a place on the St. Louis County Land Disturbance Special Inspector list. It is WBE certified and carries a BuildZoom score of 92. That licence stack is why the Missouri, St. Louis County and septic sections of this list are the deepest ones.
