Water Graphic-California's New Permanent Water Regulations Explained

California’s New Permanent Water Regulations Explained

We explain California’s new permanent water regulations, in plain language.
Why it was passed. Its effect on you. Below there is a link to resources that will help you conserve.
And, we squish one ridiculous myth flying around the web!

Freshly signed into law by Governor Brown, the bills now make water conservation “a way of life” in California. 
Bills AB 1668 and SB 606 aim to reduce water usage by twenty percent, per capita by December 31, 2020.

Background 

*Climate modeling by Climate Scientist Daniel Swain uncovers another trend – drier autumns with a late onset of the rainy season and a corresponding drier spring.  Source:  published in Nature Climate Change.   

Who is affected?
All California residents.

Why?

A high probability of future extreme drought conditions and the need to plan for them.

It will motivate agencies to repair old and inefficient infrastructure.

What do I need to know?

The state mandates local water agencies to establish water use targets based on their respective region’s climate, land use and population. 

  • Indoor water use limit of 55 gallons per person, per day through January 1, 2025.**
  • Outdoor water usage standards are not developed yet.  (includes landscapes and pools).  DWR will study climate and landscapes around the state to determine guidelines.
  • Commercial, institutional and industrial standards will be defined by 2021.

**East Bay Municipal Water District website, see link below, has information to help you calculate your own water usage.  There’s also a handy table that lists water usage for showers, sinks, washers and other household appliances.

Separating Myth from Fact

Myth

You can’t shower and wash clothes on the same day.

Fact

Not true.

Most washers now use only 9 to, at the most, 26 gallons of water.

An average shower for 8 minutes uses 17 gallons of water. 

Some Perspective

Average per capita = per person.

San Francisco’s average water use is less than 55 gallons per person, per day.

There was a 55-gallon standard set for indoor use set almost 10 years ago.

The 55-gallon limit is more than what is allowed in some countries in Europe.

There are numerous water crises in urban centers all over the world. Water pollution accounts for many of them.  Others, a result of extreme drought.  In all cases, experts say, poor water management is the reason it became a crisis.  Cape Town was expected to run out of water earlier this year, but a last-ditch policy of severe rationing  narrowly avoided a catastrophe.  The city’s doomsday alarm clock was reset for next year.

Prevention and Control of Top 7 Invasive Weeds Using the Least Toxic Practices

Our report on the top 7 invasive weeds in the SF Bay Area was re-worked from one I posted in 2016 weeds typical in the San Francisco Bay Area including the most invasive weeds.

The top 7 invasive weeds is focused on the worst for good reason. This summer promises to be hot. Some of the top 7 are highly flammable.  Our treatment options for getting rid of the top 7 emphasize the least toxic solutions. Hand pulling or mechanical means for some, at the right time, can be effective.

Our Recommendations

We suggest a combination of prevention, mechanical or biological means. 
Sometimes a chemical solution is necessary, but only that is so.
The results of 2018’s on and off rainfall and intermittent heat waves have seen a prolific  crop of bull thistle (pictured above) and oxalis.

See the full report on managing weeds. It includes 13 weed types, prevention and control.

Prevention – the First Line of Defense

Plant Choices
The right plant in the right place sounds simple but makes all the difference. 
Healthy vigorous plants have the best chance of out-competing weeds.  
Healthy Soil
Make sure that plants are healthy by feeding the soil with organic products including mulch and compost.
Mulching and Sheet Mulching
Mulch keeps soil cool and moist.  It deprives weeds of light.  Organic mulches enhance soil structure and host insects which will devour weeds.  Sheet mulching is layering of cardboard, newsletter or fabric.  It serves as a weed barrier.  Water Management
Proper irrigation is critical.
We recommend drip because the water goes directly to the root of the plant, not in between them. Spray irrigation can encourage weed growth.  

The Most Invasive Weed Types

Source: California Invasive Plant Council

Remove these plants from your garden! 
They damage our ecosystems by leaching nutrients from native species.
Some are highly flammable and at the same time consume valuable water.

Broom Species (French & Scotch)

Plentiful in forests or wooded areas. They spread along roads and appear like small trees.
Despite their pretty flowers they are toxic to humans and animals.
BEWARE. They are fire hazards. With a hot dry summer coming , get rid of these.
Crowds out desirable species by leaching nutrients.
Seeds spread by wind
Treatment Options
Hand pull between January-May

Cut to just above ground
Cut and treat with an herbicide

Fennel or Licorice Plant

Seeds spread by wind and competes with other plants for nutrients.
They will displace native plants in coastal areas.
BEWARE – This plant is also considered a fire hazard.
Treatment options
Hand pull when soil still wet.
Dig out as much of the root as possible with shovels, hand picks.
Mowing needs to be done at the right time or will encourage seed growth.

 

Bull Thistle

Showy purple blooms and sharp needle-like leaves.
Grows where soil is disturbed. Spreads rapidly.
Leaches nutrients from desired plants.
Treatment Options
Hand pull and step on stem before pulling
Mow before they flower
Herbicides

Cape Ivy

Forms a dense blanket over desired plants.
Distinguishing from less invasive ivy is difficult.
They choke off nutrients from understory vegetation, kill trees, harbor rats and snails.

Treatment Options
Requires precision as every stem must be removed.
Removing around the perimeter of a patch.
Because removal is complex cutting and using herbicide may be advised.

Himalaya Blackberry

Don’t confuse this with native blackberries!  Natives are smaller and don’t tangle and sprawl.
The
Himalayan Blackberry grows in dense thickets, covered in thorns. 
Highly invasive and difficult to
control.
They leach out nutrients from desired plants and shade out light.
BEWARE they are also a fire hazard
Treatment options
Mechanical – digging up root tall
Burning of mature plants only with consultation with a professional
Unfortunately, treating with concentrated herbicide is one of the best ways.

Periwinkle or Vinca Major

Vinca Minor is okay! The two types look a little different
Vinca Major leaves are broader, larger; heart shaped.
Vinca Minor leaves are smaller, elongated.
Major is a pest. They root wherever their stems touch soil.
They spread rapidly in shady creeks; drainage areas.  And, they choke off natives.
Treatment Options
Hand pulling will work if roots are not deep, soil is loose and moist. (put plants in plastic bag & destroy)
Mechanical means (put plants in plastic bag and destroy)
Foliar spray can work
Cutting and treating with an herbicide is effective if all else fails.

Ice Plants

Competes with native plants.
Seeds are prolific. They move from landscaped areas to natural areas.
Pieces of the plant can be washed into storm drains.
They form a dense mat which can harbor rats and contribute to soil erosion.
Research has shown that where they root, ice plants make long term changes to the soil.
A snippet from one study found that when the ice plant was removed both native and exotic plant
species returned.  But natives were less abundant.
Treatment Options
Hand puling is effective, just do it early.

 

 

 

 

 

 

 

 

Sifting through a long list of 2018 trends in landscaping and gardening, we extracted ones more closely pertaining to the San Francisco Bay Area.

These important trends reflect our changing climate and how/ what people are planting this year. 
Plus there’s a brief, but inspiring case study about an old-fashioned practice made new again.

Container Gardening
A growing population millennials and retirees are moving into multi-family and tiny housing.  They want to garden. The answer to their small space challenge is containers.
They provide color, texture and structure.
There are a myriad of choices you can find from classic to modern.  Rustic to formal. Balcony boxes.
See below.

Do’s and Don’t’s on Containers
Say no to dark colors or clay pots
Dark colors get too hot; clay dries out in summer.
Best is fiberglass, plastic or glazed pottery.
Make sure they have drainage holes.

Succulents in glazed pottery

Low Water Container Perennials
Succulents are great. Hardy. They usually need full sun.
California Poppies are native, hardy and cheerful.
Lavender – Depending on your space you might try dwarf varieties.  They need full sun.

Kale

Kale

Edible Container Plants
Among the easiest to grow are –
Lettuces, kale and herbs. Shallow-rooted, they need a container with a 9-12″ depth.
Tomato plants are larger and need a container with a 12-14″ depth.
Consider dwarf varieties as well.

What You Need
Good soil.
Know your plant sunlight and water needs. Most edibles will need four-five hours of sun.
Mulching will help your soil hold water.
Feed the soil with: compost; worm castings.
(Gardeners’ Guild has great success with worm castings.  It is odorless, natural and improves soil health). There are also natural products you can purchase at your local nursery.

Acclimating Landscapes to Climate Change
More people are taking action to prepare for the effects of extreme weather such as drought, wind, severe heat, cold and rain.  Adapting a landscape for a changing climate involves components such as design, plant types, maintenance that includes consistent and correct pruning. 
Water management is also critical in acclimating our landscapes.
Below are tips on how to prepare for these trends, what you can do and why.

High Wind Resistance
Plants, trees and retaining walls are used as wind blocks
In large areas – plants are installed in a series of staggered rows that re-direct wind around and above.
For small areas – a similar concept referred to as a wind screen.
Wind isn’t completely blocked but tempered somewhat.
Wind Resistant Plant Attributes
More flexible stems.  Examples: Escalonia, Ornamental grasses.

Fire wise plants left to right: Agave, African Iris, Beach Aster

Fire Resistant Landscapes
The Napa and Sonoma fires brought into granular focus three factors:
“Defensible space” – a high priority.  The recommended clearance from a structure is 100′.  (More details on this topic in coming months).
Planting firewise plants in the right place. (see examples above).
Gardeners’ Guild has maintained and planted many of these.

Heat Tolerant Plants
Our micro-climates are changing. Areas that used to stay cool have hot temperatures more frequently.  More people are choosing desert-like gardens.
See photos below for some plants that won’t wilt in the heat.

Heat tolerant plants, left to right: Poppies, Euphorbia and Salvia

Freeze Hardy Plants
This is a partial list of plants that can withstand freezing temperatures.
Correa ‘Ivory Bells’
Verbena Lilacina
Helleborous

Drought Tolerant Landscapes
The drought officially came and went, but it can and will re-occur.
Water bills are rising.
The state of California may reinstate water restrictions making them permanent.
Later this year we will be covering drought tolerant plants and rebates.  Stay tuned.

Multi-Family Housing and its Amenities
It has exploded in the San Francisco Bay Area’s urban areas.  In San Francisco proper, Mission Bay continues to fill in with housing and business.  A breathtaking number of luxury, state of the art buildings have been completed in the last few years.  We highlight trends that are important for Community Managers.

One trend was noted from a recent issue of Bisnow. 
An attractive landscape is a non-negotiable amenity. 
Moreover, it shouldn’t look sparse or overgrown. 
A Multi-Family executive magazine article says that a three-year plan for upgrades that include new fire pits. Or, budgeting for a top of the line grill every few years is a must.

Aside from landscaping, there is a new push for multi-family communities to offer so-called “soft amenities i.e. dog-walking, dry cleaning, packing and concierge services.

A Soil Restoration Brief

David Montgomery, a Geomorphologist and author of books about soil, wants to world to know that organic products’ ability to restore degraded soil has been proven – in his own garden!

Over the years Montgomery had become discouraged that modern agriculture is “stripping the Earth of high quality topsoil.” 

He contends that civilizations throughout history have collapsed due to the depletion of the top three inches of soil.  “The skin of the earth”, Montgomery calls it. While writing a book on the topic, Montgomery’s wife began a project to restore the soil in their backyard.

She massaged in wood chips, fallen leaves, coffee grounds. Also mulch, compost, and a soil inoculant from worm castings. A miraculous transformation took place.  It took several years – but the soil came back.

It’s now flourishing with healthy edibles.  And, Montgomery’s story has become more optimistic.
