Stormwater regulations vs a rural property

[cpacker]

I'm a computer programmer trying to make sense of storm water management regulations that affect the rural property on which I'm going to build a house. My site-planner's initial design for the wooded lot called for the removal of a stand of mature trees to make space for a rain garden. What!!? Long story short, I need to be directed to a tutorial that will let me do my own analysis: that doesn't assume an urban environment, that doesn't assume that required water retention features will be located next to the source of runoff, that lets me determine my runoff management obligations at the down-slope property boundary, taking into account the runoff coefficients of the woods between my house site and the property line.

I have only done limited work in Maryland and am not intimate with their regs. However, I don't think your field would automatically warrant a pond. I believe at minimum, it would warrant a plan with E&S controls and a report showing BMPs that are used or rationale for exemptions.

Soccer field example you would still be going from a meadow CN to lawn CN ... so some SWM would be warranted.

(This is based on PA regs, which are pretty much verbatim with MD).

Don't try to argue that your gravel driveway or parking areas are pervious. That's simply incorrect practice. They are highly compacted areas. See this for a layman's example:
