An Adams County stormwater permit may not be the only permit
A Porch Note from Colorado Porch — plain-English local details for all 64 Colorado counties.
On some Adams County construction projects, getting a stormwater permit from the county is only half the job. To complete the county SWQ permit application, you also have to hand over a copy of the State of Colorado Stormwater Permit for Construction Activity, or, if the state has not certified you yet, a copy of the application you already submitted to the state. The county permit and the state permit are two different documents, issued by two different offices.
The reason they ride together is that the Adams County permit exists to help developers and builders comply with state and federal stormwater rules, not to replace them. So the county checks for the state coverage as part of its own review. For larger or otherwise regulated grading work, that state coverage is not optional paperwork sitting off to the side — it is part of the same path to breaking ground.
The trap is assuming the county permit settles the whole stormwater question. Miss the state layer and the gap can stall the grading, right-of-way, or building permits that all wait downstream.
The cleaner habit is to figure out early whether a project needs county coverage, state coverage, or both, then keep proof of each in the project file and on site for inspectors who ask.
