In the rainy Pacific Northwest, a robust drainage system is essential to protect your property from water damage. Drainage systems manage water flow, prevent erosion, and protect your plants, hardscapes, and foundation. But which drainage system is best for your yard? Let’s explore the most common types of drainage systems and their applications, helping you make an informed choice for your landscape.
- Surface Drainage Systems
Best for: Managing heavy rainfall and redirecting water from flat areas.
Surface drainage systems are designed to move excess water away from the ground’s surface quickly. They include shallow ditches, channels, or swales that direct water to a designated outlet. Often combined with grading, surface drainage is effective for lawns, sports courts, and driveways.
Advantages:
- Quick water removal from flat areas.
- Prevents pooling on lawns or hardscapes.
Applications in the PNW:
Perfect for redirecting heavy rainfall common in Whatcom and Skagit counties. Swales can be integrated with native plants for an eco-friendly rain garden look.
- French Drains
Best for: Preventing water from seeping into your foundation or low-lying areas.
A French drain is a gravel-filled trench containing a perforated pipe that redirects water underground. It’s ideal for properties with poor soil drainage or those prone to basement flooding.
Advantages:
- Concealed design doesn’t disrupt landscaping.
- Effective at managing subsurface water.
Applications in the PNW:
Homeowners on slopes or in areas with clay-heavy soil (common in Island County) benefit from French drains as they redirect water safely downhill.
- Catch Basin Drainage Systems
Best for: Properties with high water runoff from hardscapes like patios, driveways, or walkways.
Catch basins are underground reservoirs connected to a drainage system that collect and redirect water. Typically installed at low points, they prevent standing water and erosion.
Advantages:
- Prevents water pooling on hardscapes.
- Easy to clean and maintain.
Applications in the PNW:
Ideal for homes with large driveways or patios, where heavy rainfall can accumulate and create puddles.
- Channel Drains
Best for: Driveways, patios, and pool decks.
Channel drains, or trench drains, are long, narrow grates that collect water over hard surfaces. The collected water is then directed into underground pipes for dispersal.
Advantages:
- Keeps hardscape areas dry and safe.
- Minimizes wear and tear on concrete or pavers.
Applications in the PNW:
A common choice for driveways in Stanwood and Camano Island, especially where water runoff might freeze in colder months.
- Dry Wells
Best for: Large properties or areas where water needs to be absorbed into the ground.
Dry wells collect excess water and gradually disperse it into the surrounding soil, reducing runoff. They are often paired with other drainage systems for enhanced efficiency.
Advantages:
- Environmentally friendly way to manage water.
- Reduces reliance on stormwater systems.
Applications in the PNW:
Useful in rural or semi-urban areas where storm drains are limited, especially in Skagit Valley.
- Downspout Extensions
Best for: Homes with water pooling near foundations or in gardens.
Downspout extensions channel roof runoff away from the foundation, protecting your home and nearby landscaping from erosion and water damage.
Advantages:
- Simple, affordable solution for minor drainage issues.
- Easy to install and maintain.
Applications in the PNW:
Highly effective for homes in Bellingham and surrounding areas where heavy rain is frequent.
