EBOM-2009 SSc6: Stormwater Quantity Control
For Miami-Dade County, FL.
In the SSc6 form, where do I find the "Mitigated design rainfall volume for the entire site (cu ft)? In the building
plans? Where in the building plans, because it doesn't say it under "Drainage Notes" for Site on the Bldg. Plans.

Where do I find information about the 2-year 24-hour storm for my location?
What is the best way to determine the slope of vegetated areas?
What value should we use for the runoff coefficient for our pervious paving?
What is the runoff coefficient for water bodies like pools and ponds onsite?

Hi Bryan,
If your stormwater mitigation strategy is limited to infiltration of stormwater through onsite vegetation, you can skip the Mitigated design rainfall volume for the entire site (cu ft) input. In that case select the "Full Documentation Path" and "stormwater management calculator will be completed" options on the form and then fill out the form calculator to determine the savings.
Otherwise, if your site has another type of stormwater such as retention, detention, bioswales, or other, you'll need to have an engineer or other technical expert prepare calculations. This may have been done during the design and construction process of the building site and if so, probably would have been delivered in a separate stormwater management assessment from the building plan set.
