Rain Gardens & Stormwater Solutions for Portland
Beautiful landscaping that manages runoff, reduces flooding, and protects local waterways.
A rain garden is a shallow, planted depression that captures and filters stormwater runoff from roofs, driveways, and lawns. Instead of flowing directly into storm drains or flooding your property, water settles into the garden where native plants and soil filter it naturally. The result: less standing water, reduced erosion, and a landscape feature that's both functional and attractive.
Portland's frequent rainfall and aging stormwater infrastructure make rain gardens especially valuable for residential and commercial properties. They reduce your flooding risk, lower maintenance headaches, and support the health of local streams and waterways—all while adding visual interest to your yard.
StoneFern specializes in rain garden design and installation tailored to Portland properties. We assess your drainage challenges, design a garden that fits your landscape, and plant it with native species that thrive in moist conditions. The result is a beautiful, low-maintenance solution that works with Portland's climate, not against it.
How Rain Gardens Work
Rain gardens are simple but effective—they capture stormwater runoff from your roof, driveway, and lawn, then filter it through native plants and soil back into the ground. This reduces flooding, protects your foundation, and recharges local groundwater. Here's how StoneFern designs and builds them for Portland properties.

1
Design Assessment
We visit your property to evaluate slope, soil type, and drainage patterns. This tells us where water naturally flows and where a rain garden will work best. We also check for utilities and plan the garden's size and depth based on your roof area and local rainfall.

2
Excavation & Preparation
We dig a shallow basin—typically 4 to 8 inches deep—in the best location. The basin is graded to gently slope so water flows in and settles. We add a layer of compost and amended soil that filters water while supporting healthy plant growth.

Native Plant Selection & Planting
We fill the rain garden with native Portland plants chosen for moisture tolerance and stormwater filtering ability. These plants thrive in wet conditions, require minimal maintenance, and support local wildlife. The mix typically includes sedges, rushes, dogwoods, and other water-loving natives.

Establishment & Long-Term Care
During the first season, we water new plants to help them establish strong roots. Once established, rain gardens are largely self-sufficient—they rely on natural rainfall to thrive. We handle seasonal maintenance like weeding and mulch refresh to keep everything looking attractive and functioning well.

Water Filtration & Recharge
As water sits in the basin, soil and plants filter sediment, pollutants, and excess nutrients. The filtered water gradually percolates down, recharging groundwater and reducing the stormwater burden on Portland's systems. Most rain gardens drain completely within 24 to 48 hours after a storm.

When You Need a Rain Garden
A rain garden isn't just for environmental enthusiasts—it's a practical solution for common Portland property problems. If any of these scenarios sound familiar, a rain garden might be the answer.
Yard flooding or standing water after heavy rain
If your yard turns into a pond during Portland's rainy season, a rain garden captures and filters that water instead of letting it pool. The water soaks into the ground naturally, eliminating standing water and the mosquitoes that come with it.
Erosion or runoff damage to landscaping
Heavy runoff washes away topsoil, damages plants, and carves erosion paths across your property. A rain garden slows water flow and filters it through soil and plants, protecting your landscape while recharging groundwater.
Basement or foundation water issues
Water pooling near your foundation can seep into basements and cause costly damage. By capturing runoff before it reaches your home's foundation, a rain garden keeps water away from vulnerable areas.
Poor drainage in low-lying areas
Some yards have natural low spots where water collects and won't drain. A strategically placed rain garden transforms these problem areas into attractive, functional landscaping that actually improves your yard's usability.
Environmental and stormwater management goals
If you care about reducing stormwater runoff and supporting Portland's local waterways, a rain garden is a tangible way to make a difference. Native plants filter pollutants and sediment while managing the water that would otherwise overwhelm storm drains.
