What matters for project planning
The stormwater program does not govern remediation, and it would be padding to suggest otherwise. Where it earns a mention is one step upstream: most persistent moisture in this metro is a site-drainage problem before it is an indoor one, and the 2020 update to the city's design and discharge standards is aimed squarely at how water is handled on a lot. That matters in a practical way here because Huntsville keeps adding infill beside much older subdivisions -- a new build next door can change where water goes on an established property, and a crawl space that stayed dry for thirty years can start taking water for reasons that have nothing to do with the house itself. Where correcting a moisture source means regrading or altering discharge, current requirements are worth confirming with the city before the work is scoped.

Verify the property, not just the city
General city-level information can't tell you whether your specific parcel sits in a flood zone, falls under historic-district review, needs a permit, sits on karst-prone soil, or hides construction issues behind the walls. Check those specifics with the City of Huntsville and your chosen provider before any work starts.
