Quantifying Stormwater Benefits of Trees Part 2: Single-Event Stormwater Models by @rethinktrees
The accuracy of the model is defined by the quality of the coefficients these models use. Your specific geographic location and the actual area rainfall characteristics generally are not part of these models, as the information is more generalized for broader applications – therefore the information may or may not reflect what you actually see on your site. Your goals in using these methods should be similarly scaled back; e.g. don’t go buy a manhole and start setting pipes based on the recommendation of your Single-Event Model! But if you just need a rough estimate of the stormwater volume you need to store and the size of your bioretention pond, this would work well.
