California's water supply is more fragile and seasonal than in most of the country because we are in "the West". Seasonal rains in our desert areas can be severe, and water retention for the rest of the year is dependent on snowpack, water tables and manmade lakes.

When rains come, we need to capture that fresh water for use by the flora and fauna in our communities. Capturing it also prevents runoff from roofs, streets, parking lots and lawns from washing pollutants into streams, rivers, lakes and eventually the ocean. Runoff pollutants can include fertilizers, pesticides, car waste such as oil and fluids, pet waste and its bacteria, eroded soil, road salt, grass clippings and litter. Rain gardens will not remove ALL these pollutants, but they do remove some of them as the water seeps into the ground, which serves as a natural filter.

A beautiful, useful way to capture rainwater runoff is with a "raingarden" that is well designed, well placed and serves as a cache basin that filters and helps the water find its way to the roots of plants...and our watertable.
