Drought Resistance Outreach Program for Schools rain garden celebrated at Ukiah High
Prior to the installation of the system, the rain garden was hardpan dirt, allowing all the rainwater—contaminated and polluted with oil, gas, sediment, cigarette butts and plastic wrappers—to drain directly into Orrs Creek and the Russian River. The new garden is 3- to 5-feet deep and composed of carefully constructed layers of soil and rock, allowing the water to be cleaned mechanically and biologically filtering the biocontaminants.
