Gearing Up for El Niño: Is Your Sonoma County Landscape Ready for Winter?
After several years of unpredictable weather, Sonoma County homeowners know that winter can bring more than just a little rain. NOAA's Climate Prediction Center recently reported that El Niño is strengthening, with a greater than 90% chance of a very strong event during the fall and winter of 2026–27. While El Niño doesn't guarantee exactly how much rain we'll receive locally, it's a good reminder that now is the time to take a closer look at how your landscape handles water. Heavy rainfall can quickly expose problems that may not be obvious during the dry season. Standing water, poor drainage, erosion, and runoff can all create issues for your landscape and your property.
Here are a few things to consider before the rainy season arrives.
Pay Attention to Where Water Goes
The most important question to ask is simple: Where does the water go when it rains?
Take note of areas where water tends to collect or flow. Does runoff move toward your home? Do certain areas of your lawn or garden stay saturated? Are there places where soil washes away during heavy storms?
These are all signs that your landscape may need better drainage or grading.
A thoughtfully designed landscape should direct water away from structures while managing runoff in a way that works with the natural conditions of the property.
Check for Drainage Issues Before the First Big Storm
It's much easier to address drainage problems before you're standing outside in the rain watching water pool where it shouldn't. Check drains, drainage swales, culverts, and other areas designed to move water through your property. Remove leaves and debris that could cause blockages and make sure downspouts aren't directing large amounts of water into problem areas. For hillside properties, it's especially important to pay attention to changing drainage patterns and areas where water converges, as heavy rainfall can contribute to erosion and slope instability.
Watch for Erosion
Heavy rain can move more than water. Sloped areas, exposed soil, and areas with poor drainage can be vulnerable to erosion during winter storms. Over time, runoff can wash away soil, damage planting areas, and create larger drainage problems. Planting, grading, retaining features, and erosion-control strategies can all play a role in helping stabilize a landscape and manage water more effectively.
Consider a Dry Creek Bed
Dry creek beds aren't just beautiful landscape features. When thoughtfully designed, they can also help direct and manage stormwater runoff. These natural-looking features can create a designated path for water to move through the landscape during heavy rain while adding texture and visual interest throughout the rest of the year. For properties that regularly experience pooling water or concentrated runoff, incorporating drainage solutions into the overall landscape design can make a significant difference.
Don't Forget About Your Irrigation
As the rainy season approaches, your irrigation system should be adjusted accordingly.
Automatic systems that continue watering as though it's summer can create overly saturated soil and waste water. Checking your irrigation system before winter allows you to identify leaks, make seasonal adjustments, and ensure everything is functioning properly.
Think Beyond This Winter
Preparing for a wet season isn't just about reacting to the next storm. It's about understanding how your property performs over time. If your landscape regularly experiences standing water, erosion, flooding, or drainage problems, it may be time to look at the bigger picture. Sometimes the solution isn't simply adding another drain. It may involve grading, drainage improvements, planting strategies, or a more comprehensive landscape design.
