How Rain Gardens Work
A rain garden captures and filters stormwater naturally, turning a problem into an elegant solution. Here's what happens, step by step.
-
1
Water Enters the Garden During Rain
When Portland's rains arrive, water flows from your roof, gutters, and surrounding landscape into the rain garden basin. Instead of running off into storm drains or pooling on your property, it's directed into a shallow, planted depression designed to capture it.
-
2
Native Plants and Soil Filter the Water
The rain garden is planted with native species adapted to Portland's climate—plants whose roots naturally thrive in wet conditions. As water sits in the garden for 24–48 hours, the soil layers and plant roots filter out sediment, pollutants, and nutrients that would otherwise wash into storm drains and local waterways.
-
3
Water Infiltrates into the Ground
The filtered water slowly soaks into the soil beneath the garden, recharging groundwater instead of being lost to the storm sewer system. This is the heart of stormwater-aware design—water returns to where it belongs, supporting your landscape and the broader aquifer.
-
4
Excess Water Drains Safely
For extreme storms, the rain garden includes an overflow mechanism—a spillway or drainage outlet—that safely directs any water that doesn't infiltrate away from your home's foundation. This means your property is protected even during Portland's heaviest downpours.
-
5
Seasonal Maintenance Is Minimal
Once established, native plants thrive year-round with little intervention. There's no need for irrigation—Portland's rainfall keeps them healthy—and no chemical fertilizers or pesticides required. A light seasonal cleanup and occasional weeding are all you need. The plants do the work; you enjoy the results.
Rain Gardens Solve Real Problems
Rain gardens do more than manage water—they protect your home, support local wildlife, and create a thriving native garden that requires minimal maintenance. Here's what they actually deliver.
