10 Water-saving ways to replace your lawn (and still have the nicest yard on the block.)

Take a nice Sunday drive in most California neighborhoods and you’ll notice something different. House after house, the front lawns are browning. They are still cut and landscaped neatly, and the homes are impeccably cared for, but the grass is so dry it almost looks scorched. And it’s not just our lawns – you’ll see it on the grassy median of highways, public parks, and even the vast grassy promenade in front of the state capitol in Sacramento.

The browning of California’s grass has become the new reality as we face the most serious draught in our history, with no end in sight. In fact, an alarming 63 trillion gallons of water has been lost in the west over just the last 18 months. Scientists are now alarmed that as the water deficit accelerates, relieving the ground of 240 billion tons of weight in H20, the ground is actually shifting and rising. Conservationists and municipalities have tried to sound the alarm, instituting no-watering days for lawns, washing cars, and trying to educate the public as to how cut back. But so far, our collective water bill hasn’t significantly shrunk – and we still insist on having putting greens in front of our homes.

So what can we do? The EPA estimates that the average American household uses 320 gallons of water a day, with about 30-60% of that in dry climates devoted to outdoor irrigation. Of that, more than half of it is dedicated to watering lawns, but up to 60% is wasted by over-watering, inefficient methods, and waste.

Point blank – we can install low-flow toilets, cut our shower time in half, and stop washing our cars, but the real and immediate impact into water usage will come from irrigation; our lawns. The good news is that many communities in arid climates like Arizona, New Mexico, or abroad, have already been through this and adjusted their landscaping accordingly. 

So here are 10 alternatives to front lawns that will vastly reduce our collective water usage – and save you a big chunk on your next water bill. Hopefully when we take a drive around the same California neighborhoods in a year or two, we’ll see beautiful natural landscaping that conserves water in front of most homes – not lawns.

1. Lay natural rocks and fill in groundcover in between for a “hardscape.” It will require almost no watering and naturally keep weeds out, bust still offer greenery.

2. In areas that remain shady most of the day, plant moss. Since it’s not a deeply rooted plant, it will transplant very easily and within as little as 4-6 weeks it will take hold and spread, but never take over.

3. Plant beds of creeping thyme. It looks delicate but it’s actually a very tough and resilient low-water plant that will remain green all year, while also providing great fragrance. You never got that with your lawn!

4. Construct a brick or flagstone zero-scape, placing potted plants or small “oasis” areas throughout. Fill between them with mortar to eliminate weeds sprouting up.

5. Or, you can lay flagstones or pavers and fill in with your beloved green grass, or natural grasses. You can make great symmetrical patterns with these that make your property look bigger, or mix it up to replicate the beautiful chaos of nature.

6. As a general rule, think about plating flora that occurs naturally in your climate and geography. For most of California, that is not green grass and big oak trees!

7. Speaking of trees, you can take out the grass but plant a host of low-water, hot-weather trees, including almond, olive, avocados, figs, almonds, and pears, among others. Not only will you be able to enjoy the fruits of your labor (and nuts) but these will attract native birds and butterflies and keep your home cooler with their shade.

8. A fantastic alternative to grass is to fill surface area with sand, native crushed pebbles, or and crushed stone. You can still fill in with rocks, flowers, and plant groupings to make your yard the envy of the neighborhood – but with very little watering.

9. Synthetic grass. We hate to mention an artificial alternative when there are so many other great ways to replace your lawn, but if you must have that perfect putting green front yard, they make amazing synthetics these days. They aren’t cheap but you’ll never have to water again.

10. A new trend in landscaping is to replicate the natural ecosystem, planting native species of draught-resistant grasses, flowers, shrubs, and trees but then letting them grow wild. By using native species you’ll ensure these plants require little water and thrive in our climates. After all, there is no better landscaper to emulate than Mother Nature!

California's draught is getting critical - but how can we help?

California has a history intertwined with precious natural resources.  First, it was gold that led people to go west, young man, establishing our home state around the epicenter of Sacramento and its well-panned hills and rivers.  Next, it was oil in the 1970’s and 1980’s, as shortages drove the most populous state in the country scrambling for alternatives to big cars and big power.  Now, it’s water shortages that pose the most daunting dilemma for our Golden State, a crisis so profound that it goes far beyond jut cutting back on watering lawns and turning off faucets around the house, and even a spell of good rain won’t solve this problem.  It’s an issue two decades in the making, culminating now with looming shortages so profound that water might be the most singly important issue this upcoming political season. 

The central valley and the seat of government of the world’s 8th largest economy are now some of the most affected areas, and experts are now screaming for politicians and the populace alike to pay attention.  Will the necessary adjustments be minor inconveniences or substantially impact our quality of life?  Will these shortages push us into a new green era of efficiency and sustainability?  Just how bad are the water shortages in California and the Sacramento region?

Last year was the driest in state history since records started being kept in 1895, and this year looks to be significantly drier.  One of the largest single sources of water for California, the states’s snowpack from Lake Tahoe and other peaks, accounting for one-third of the water used by our cities and farms, sits at only about 20% of its normal water content.  The water level in crucial reservoirs is even lower than in 1977, one of the two driest years on record.  Recently, a state spokesman announced that 17 rural communities were within 100 days of running out of drinking water if its current pattern of water supply and usage continued unchanged.  Even if it rained every other day through May, the drought still wouldn’t be alleviated because it’s been so dry the past two years.

Anecdotally, the impending water shortages are leading some to anticipate a modern version of the 1930’s Dust Bowl.  Governor Jerry Brown, whose reelection bid could be hinged to his ability to negotiate water shortage solutions, warned in February that the state was facing a mega draught. 

In January, Gov. Brown called for California’s to reduce their water usage by 20%, followed by emergency draught legislation that promoted the use of recycled water, among other measures.  Placer County declared a Drought Emergency on February 6th, looking for reductions of indoor water usage by 25% and outdoor usage by 50%. 

These water saving measures sound great, but rarely do they take hold and actually cause significant conversation.  At least, that’s the consensus based on the last legislation, 5 years ago when Gov. Brown called for Californians to reduce their water consumption by 20%, a goal we were supposed to hit by 202.  But new studies show we’re not anywhere close to achieving that.

There’s plenty of finger pointing to go around – homeowners for not having water meters installed on their homes, environmentalists for blocking new damn and waterway construction projects, and especially farmers, who still use water-wasting open irrigation techniques.  In fact, farmers are seeing the biggest consequences to this draught already, which supply about half of the countries fruits, nuts, and vegetables.  They’re proactively destroying certain crops, like almond trees, that are thirstiest.  It’s expected that half a million acres of agricultural and farmlands will go fallow over the next couple years because of water shortages, and food prices have already started to creep up, reflecting that.

So what might this look like to the average person?  Small measures – often interpreted as inconveniences – trickle down first.  Local governments have called for restaurants to stop serving drinking water unless specifically requested.  Driveways can’t be hosed down, cars can only be washed with water in buckets, and showers should be voluntarily shortened.  Hotels are supposed to wash linens daily only if customers specifically ask, and landscapers are being asked to plant only drought-tolerant plants. 

What are the best ways responsible citizens can do their part to cut back on water usage? 

Where do families and homeowners use the most water?

A typical three-bedroom single family home in California uses 174,000 gallons a year.  That's broken down as:

-Shower 17%
-Kitchen and bathroom faucets 9%
-Toilets 4%
-Clothes washer 4%
-Landscaping 57%
-Over watering 9%

Water saving solutions:

-Low-flow toilet $60-$200
(Saves 6.4 gallons per flush)

-Faucet aerators
Cost $2
(Saves 1.5 gallons per minute)

-Low-flow showerhead
(Saves 2.5-3.5 gallons per minute)

As we can see, rampant overwatering of landscaping and lawns is the single biggest wearer waster.  Consider watering manually, or definitely set the auto timers on your sprinklers for recommended watering days.  Take a weekend trip to Home Depot or have someone install low-flow toilets, shower heads, and faucet upgrades to cut back.  Additionally, it’s important to pay attention to the water-saving legislation already in effect.  California Senate Bill 407 calls for changes for homeowners by January 1, 2017 - all residential properties in California that were built prior to 1994 will be required to retrofit with:

-Toilets that use no more than 1.6 gallons per flush
-Showerheads with flow rates of no more than 2.5 gallons per minute
-Other interior fixtures that use less than 2.2 gallons of water per minute.
