How to Keep What Rainfall Your Yard Gets
Rain. Some of us get more of it than others. In some cities it pours most of the year, while in others total annual rainfall is measured in a tuna can. You might not need to conserve as much water if you get a lot of rain. But even in high-precipitation areas of the country (and world), it’s more about infiltration than how much rain falls.
Infiltration is king when it comes to making the most use of rainfall. In areas where soil is exposed and compacted, water can’t make its way in. Instead, it sheets over the top of the soil. This means it ends up in the ill-conceived street drainage system. I say ill-conceived because the storm water engineering we’re all living with was designed to carry water away, not into, the landscape.
