It’s not only possible it is easy to have a beautiful garden that also handles 100% of your stormwater runoff. 

Rain gardens can absorb the rain water and filter out toxic pollutants in the stormwater run off. This naturally manages the stormwater run off and ensures that the run off and all of the pollutants in it aren’t rushed out into the street and then into lakes and rivers. Follow this formula to make sure that the rain garden you build is big enough to handle all of your stormwater run off. 

First, find out if you have clay or sandy soil. If you have clay soil it will need to be 60% of the drain area to handle all of the run off while sandy soil only needs to be 20-30% of the drain area. 

Here is how you figure out what your drain area is. 

Drain Area = (roof width x roof length) + (pavement width x pavement length)

So, after some elementary math you are now ready to set up your rain garden! There are lots of different design options once you have figured out how big of a garden you want. You can create your very own or set up the garden using these sample rain garden designs.
