Lately, when it rains, it pours! Frequent and heavy rainstorms have develop into the norm, making our present drainage programs overwhelmed and inefficient. Come rain or shine, let’s get your backyard prepared for any sort of climate Mom Nature throws at it.
Atmospheric rivers at the moment are a part of each West Coaster’s on a regular basis dictionary. What was as soon as an irregular, minor sort of rainstorm is now one thing that we are able to anticipate a few instances a yr.
And it’s not simply us on the west coast. From hurricanes to intense storms, locations everywhere in the world are experiencing elevated flooding points. It’s our new actuality.
Our outdated infrastructure and programs for coping with all this rain and flooding simply aren’t slicing it anymore. It’s time we made a giant change.
An atmospheric river hit Vancouver a month in the past, and it was a giant check for my new backyard and drainage system. I’m pleased to say that my adjustments made an enormous distinction in stopping my yard from changing into one huge puddle…not less than a part of it. Extra on that later.
By means of some easy design adjustments, your yard can develop into drainage heaven, all whereas being extra ecologically pleasant. Actually, it’s a win-win for everybody.
Right here’s what I’ll be speaking about at the moment…
The Atmospheric River Downside
A few month in the past, Vancouver had a big atmospheric river. Many areas had greater than a month’s price of rain in simply 48 hours. And for a spot that’s identified for its rain, nicely, you possibly can think about how a lot that was. North Vancouver noticed about 350 millimetres of rain over the course of three days.
Simply three years in the past, we had a record-breaking atmospheric river that utterly washed out elements of the freeway, slicing off Vancouver from the remainder of Canada and inflicting main flooding and injury to a big portion of the West Coast.
Atmospheric rivers are fairly widespread. They’re lengthy and slim concentrations of water within the sky. Whereas they will occur wherever on the earth, they’re widespread alongside the west coast of Canada and the USA due to our mountain ranges that push the air up, permitting the water to condense after which develop into rainfall.
Whereas they could be widespread, atmospheric rivers are sometimes weak and simply go unnoticed as common rainstorms. For this reason most of us have by no means heard of atmospheric rivers till current years—as a result of they’re getting extra intense.
In simply 2019, California began rating atmospheric rivers on a scale of 1 to 5, just like hurricanes. Whereas it’s not applied in Canada but, the record-breaking atmospheric river three years in the past was known as a class 5. And the one this previous October, a class 4.
It’s no coincidence that these occasions have gotten extra commonplace. The Canadian Local weather Institute reviews that the rise in rainstorms comes from hotter air on account of local weather change. The elevated quantity of heat-trapping gases within the ambiance holds extra moisture till all of it comes down in additional intense storms.
The Significance of Rain Gardens
If we didn’t have buildings, the place would our rain go? It could go proper into the bottom, in fact!
Top-of-the-line options for many rainfall is a rain backyard. These are specifically designed landscapes that take and soak up rainwater after which filter it.
The crops and soil will assist to retain water the place it belongs, however the soil will even assist to take away contaminants from the roof or pollution that may in any other case go down the drain.
One other profit? Your gardens retain all that water, which places them in a greater place when drought strikes. As a result of deep down, there’s most likely nonetheless loads of moisture.

My Entrance Yard Rain Design
Once I first purchased my home, my entrance yard was in determined want of some TLC. It was stuffed with uneven floor and have become mud puddles when the rain would hit.
Clearly, I had a drainage downside.
The very first thing I did, which I all the time advocate in my talks and in my e-book The Regenerative Backyard, was to redirect the downspouts to the yard as an alternative. I wished to keep away from my water going into town’s drainage system. In any other case, that water can be gone for good, and my backyard would have misplaced all this precious moisture.
Once we direct our gutters and spouts to town water therapy and sewage water, that water will get pumped, processed, and despatched again to us. It’s very, very wasteful.
I redirected my downspouts to go to the center of the garden so water might pool away from the home. Then, I added a dry river that may act as a basin to carry any extra water and hold it away from the crops in order that they wouldn’t get waterlogged.
Final fall, I planted over 1500 spring bulbs, after which within the spring, I planted a wildflower garden on high of all of it. This meant I had loads of crops and root programs to assist soak up and filter the water.
In the summertime, I didn’t need to water my wildflower garden as soon as. It was extraordinarily drought tolerant, and truthfully was the discuss of the block with how lovely it was.
So, I crossed my fingers and hoped that the wildflowers, bulbs, and the dry river would act as helpful rain backyard this wet season.
How Did My Rain Design Maintain Up?
When the atmospheric river hit, solely my entrance yard had completed its renovation. The yard was nonetheless incomplete and undoubtedly not ready for a lot rain. The garden was flooded, and a few of it was coming into the basement as a result of there was simply a lot water.
My drain tiles weren’t failing, there was simply a lot further water overflowing from my neighbour’s home and mine, that the water desk grew to become actually excessive. Basically, my yard had was a pond.
However in my entrance yard, I truly had actually great drainage as a result of there have been so many roots from the wildflowers and the bulbs. It broke up the soil, and the gutters weren’t pooling water beside the home.
I even checked beneath the entrance porch with a flashlight to see if any moisture was coming in from the entrance partitions, and it wasn’t!
My system handed about as strict a check as you will get. It went from a struggling garden and dirt pit to a phenomenal wildflower garden that was as purposeful because it was lovely. They work as a extremely nice resolution for drought in the summertime and heavy rains within the winter months.
I’m actually excited in regards to the design as a result of it really works rather well as a local weather change backyard. Conserving as a lot water the place it falls as doable reduces waste.
Updating Our Cities’ Infrastructure
It’s clear that Vancouver must utterly rethink its rainwater administration. Certainly one of its most up-to-date options is to put in rainwater detention tanks, which sit beneath the bottom and briefly maintain rainwater and slowly launch it into the sewer system.
However nonetheless, that is draining the water to go elsewhere moreover the place it was meant to fall. Even this UBC professor thinks that making rain gardens is an effective resolution for town.
That is one thing already taking place in Seattle. In collaboration with the King County and the Seattle Rain Clever Program, they’re implementing Inexperienced Stormwater Infrastructure.
Relatively than take all that stormwater and run it instantly into the ocean, they’re discovering extra methods to take the storm water and return it to the bottom.
Primarily, they’re utilizing rain gardens, a mix of crops, timber, soil, and sensible engineering to seize, decelerate, and clear storm runoff.
Within the Surrey and Delta space, the Cougar Creek Streamkeepers are additionally doing superb work. Made up completely of volunteers, they’re devoted to defending the well being of Cougar Creek, a salmon stream within the space.
They assist create rain gardens to scale back stormwater injury to the creek and supply ample schooling on the significance of returning this water to the land. The extra we return water to the place it comes from, the extra we’re sustaining the ecology.
If our water, from say Surrey or Delta, will get eliminated and piped out to the ocean, it doesn’t go into Cougar Creek, after which the salmon don’t get sufficient of a habitat.
Simply think about how helpful it might be if each home had a rain backyard, a rain barrel, or a water cistern. We would cut back a lot water waste, make our backyards extra ecologically pleasant, and assist ourselves come drought season.
