Mayor Highlights Water Conservation System

Los Angeles Mayor Eric Garcetti highlighted Cedars-Sinai’s groundwater conservation program, calling it an example of innovative conservation as the city seeks to reduce water consumption. The project has slashed the medical center’s use of city-supplied water by 29 million gallons annually, the equivalent of supplying 267 single-family homes with water for a year. Garcetti toured the underground water system at Cedars-Sinai with executives from the Los Angeles Department of Water and Power and the Metropolitan Water District of Southern California. “Los Angeles is changing how we think about water, by rewarding those who conserve,” Garcetti said.

Great Groundcovers To Consider as Lawn Substitutes

You may have decided to replace your thirsty traditional lawn in your new sustainable landscape. What options are available for  some kind of natural plant element rather than covering the same area with hardscaping?  

Consider replacing the lawn with a groundcover type plant. There are many good choices that make good lawn substitutes and grow well in San Diego’s six climate zones. Several of them fall into the very low or low Plant Factor categories, which means they require less water than the same amount of grass.  

Very Low Plant Factor choices include: 

  • Silver Carpet (Dymondia margaretae) 
  • Bluff California Lilac (Ceanothus maritimus)

Low Plant Factor choices include:  

Lawn Substitutes groundcovers

Bee’s bliss sage also attracts valuable pollinators.

  • Pink Yarrow (Achillea millefolium rosea) 
  • Gold Coin Plant (Asteriscus maritumus) 
  • Sundrops (Calylophus hartwegii)
    Carmel Mountain ceanothus 
  • Dwarf Mat Rush (Lomandra longfolia) 
  • Bee’s Bliss Sage (Salvia) 
  • Wooly Thyme (Thymus pseudolanguinosus) 
  • Blue Chalksticks (Senecio serpens) 

Moderate Plant Factor choices include: 

Beach Strawberry lawn substitutes

Beach Strawberry makes an attractive lawn substitute.

  • Creeping Manzanita ‘Carmel Sur’ (Arctostaphylos edmunsii) 
  • Beach Strawberry (Fragaria chiloensis) 
  • Pink yarrow, sages, and lilacs also support the lifecycle of butterflies, which are important pollinators.

Inspiring Change at The Water Conservation Garden

Horticulture director embraces educational mission

WaterSmart landscapes are transforming San Diego County’s neighborhoods in part due to the work of Paul Redeker and his colleagues at The Water Conservation Garden in El Cajon.

“We’re a learning center, not just a place where you’re surrounded by beautiful plants,” said Redeker, who recently returned for a second run as director of horticulture and facilities the garden. “All of our exhibits are geared toward teaching. We are all about educating the public to be inspired to make changes in their lives because we’re literally at the end of the water pipeline.”

Driving that point home is a giant pipe protruding from a landscaped embankment with water trickling from its opening into a lily pond near the entrance to this one-of-a-kind, six-acre conservation showcase on the campus of Cuyamaca College.

“I love the educational element,” Redeker said. “The learning that goes on in this garden regarding low-water options is wonderful.”

‘Wonderful’ low-water options

Opened in 1999, The Water Conservation Garden is owned by a joint powers agency comprising the San Diego County Water Authority, the Otay Water District, the Helix Water District, the Sweetwater Authority, the City of San Diego Public Utilities and Cuyamaca College. From the start, the garden was seen as an important conservation tool in a region with few natural water resources.

More than 30,000 people visit each year, and the garden’s programs reach an additional 80,000. It is the educational element that lured Redeker back. “The learning that goes on in this garden regarding low-water options is wonderful,” he said.

Born and raised on a Sonoma County ranch, Redeker earned his bachelor’s degree in ornamental horticulture, with a focus on landscape design, from Cal Polytechnic State University at San Luis Obispo. He worked at several Northern California nurseries before exploring other career interests overseas.

Redeker returned to California and was designing landscapes for a San Diego company when he fell in love with public gardens and landed a position as The Water Conservation Garden’s director of horticulture more than 10 years ago.

After five years in El Cajon, he expanded his professional expertise at the San Diego Botanic Garden, another regional showcase garden in Encinitas. “It gave me a wonderful understanding of how larger gardens operate,” said Redeker.

A constantly evolving gem of a garden

Redeker returned to his “little gem of a garden” last fall, and he is thrilled with the opportunities to innovate. “We are always looking to improve the experience so that when people come back, they can see something new and fresh,” he said.

Projects under way or in the planning stages at The Water Conservation Garden include:

  •  An interactive irrigation exhibit to help visitors understand and appreciate different types of water-saving technologies.
  •  A watershed exhibit with a “follow the raindrop” feature that illustrates the benefits of strategic stormwater management.
  •  More than a dozen strategically placed, drought-tolerant trees – including the Silk Oak , Blue Atlas Cedar, Sweetshade, and the Variegated Brisbane box – have been planted throughout the garden to help keep summertime temperatures in check.
  •  An expanded indoor classroom that will more than triple capacity to nearly 100.
  •  A new outdoor classroom, covered with a shade structure, will replace the current outdoor class space.

“The new classroom is going to be huge for us,” said Pam Meisner, the garden’s director of operations and programs. “We simply don’t have the room to accommodate demand for all of our adult-education landscaping and gardening classes.”

Among the permanent features is a Retrofit Backyard Exhibit that includes a traditional backyard lawn – complete with a depiction of a homeowner struggling to mow a greenbelt that drinks some 28,000 gallons of water annually – adjacent to a more visually appealing, and less labor-intensive garden featuring drought-tolerant plants that uses just 6,000 gallons of water each year.

“People are being smarter and much more creative with what they’re doing with their landscape,” said Redeker. “We’re seeing smarter plant choices, more hardscape, more patios, more mulch, dry streambeds and the like, and it’s making a difference.”

Desert Residents Have Been Saving A Lot Of Water. Farms And Golf Courses, Not So Much

Every day, millions of gallons of water flow through pipes across the Coachella Valley and pour out to nourish lawns, artificial lakes, farmlands and a total of 121 golf courses. This lush oasis in the desert owes its existence to groundwater pumped from the aquifer and an imported supply of water from the Colorado River. And during the past decade, public records show the area has made progress in using less water overall and in combating the long-term problem of groundwater overdraft.

Why 96 Million Plastic ‘Shade Balls’ Dumped Into The LA Reservoir May Not Save Water

In 2015, the world watched as a video of 96 million “shade balls” getting dumped into the Los Angeles Reservoir went viral. The purpose of the balls: to improve water quality and save water. But a new study raises an interesting question: Could saving water in the Los Angeles Reservoir come at the cost of consuming water in other parts of world? At the time, Californians faced a record-setting drought, and conserving water was on everyone’s minds. Mandatory water restrictions led to brown lawns and shorter showers.

OPINION: Water The West: Changes To Our Water Usage

Gov. Brown declared the five-year drought ended in 2017. However, water conservation never stopped being important. Hotter weather for longer periods and less precipitation have created conditions calling for unprecedented lifestyle changes. Water levels are dropping above-ground and underground, and rain and snow pack are diminishing in frequency and depth. As temperatures increase, the elevations of snow pack increase. Mountains get smaller at the pinnacle, so there is less surface area for snow pack. Higher temperatures mean less snow and, theoretically, more rain, but has received little of either in recent years.

New State Water Conservation Laws Set For 2019

In less than six months, California will begin to enact new statewide water conservation laws. Senate Bill 606 and Assembly Bill 1668 call for new urban-efficiency standards for indoor and outdoor uses, water lost to leaks and appropriate variances. The bills will take effect in 2019, although there will a grace period before enforcement, according to Mario Remillard, water conservation specialist for the Carlsbad Municipal Water District. Additionally, water agencies are required to stay within their water budgets regardless of current drought conditions. However, the California State Water Board will not enforce these standards until November 2023.

The Right Way to Remove Your Lawn

If you have made the decision to replace your thirsty, water-guzzling grass, you need to plan your grass removal process carefully to ensure you leave healthy living soil ready for new landscaping in its place.  

Here’s how to do it: 

First, keep your grass moist until you remove it. Don’t withhold irrigation and let it turn brown as it dies off. Healthy microbes in your soil will die off along with the lawn. You want to work with those microbes to help create healthy soil for your new plants. It’s also a lot easier to remove fresh, moist grass than to try and pry out dead dry grass and weeds in hard dry soil.  

Keep your soil microbes healthy to support your new landscaping

Along the same lines, don’t “solarize” your landscaping in the effort to remove your lawn. Solarizing is sometimes used as a way to remove grass with chemicals. It uses a covering such as a heavy black plastic tarp to broil the lawn at high temperatures using sunlight and kill it. But that process kills everything, including healthy microbes you need for healthy soil. Yes, you can replace them with compost, but you will need to invest in a lot of compost to restore the good microbes after you’ve removed the grass by solarizing. 

 Solarizing also backfires because sterilized soil is ideal for weeks. The moment you remove the plastic, opportunistic weeds will move in fast to try and take over the ground. It isn’t because you failed to kill the weed seeds in the soil. New weeds can arrive in a flash, and there is nothing to prevent them taking over.  

Avoid compacting or tilling your soil when removing old turf

Avoid compacting your soil. If you use heavy equipment to remove your old turf, the weight of the equipment will compact the soil underneath. Try to minimize the use of heavy equipment and use walk-behind equipment with hand tools where possible, reserving the use of a tractor or scraper only where necessary.  

Avoid tilling your soil. Tilling soil breaks up and kills your soil microbes. Without the microbes, you’re guaranteed to have those weeds pop up for a long time until new soil microbes develop.  

When removing your grass, protect your trees. If you want to preserve your healthy trees while removing your lawn, you need to be careful with their roots. Don’t use any heavy equipment to remove turf around your trees. Avoid the entire area under the canopy of the tree’s branches. Tree root structures extend all the way out to the drip line at the edge of the leaves. Keep your trees well-watered during the removal process to help minimize root shock.  

Guard against shock to trees from reduced irrigation

When your new sustainable landscaping is installed, your previously existing trees may go into shock when irrigation is reduced overall in your garden. After all, this is one of the reasons for removing your lawn. Pay special attention to keeping the trees watered during the first year after your grass is removed, even if you remove the surrounding original irrigation.  

A good way to hand-water trees is to punch holes in a five-gallon plastic bucket. Fill the bucket, set it down at the edge of the tree canopy, and let the water slowly seep into the ground. Repeat the process three to four times to water your beautiful mature trees. This mimics the natural rainfall Mother Nature provides.
