Rethink stormwater – waste or asset?

When it rains and all the raindrops fall on our roofs, have you thought about where the stormwater go to?  Well, most of it just goes down the sewer, into the creeks and rivers, and eventually out to the ocean.

stormwater

Stormwater – a waste?

Stormwater has been treated as something akin to waste in cities, something that is collected and sent out as soon as possible.  A complete infrastructure is in place to get this done: gutters and downspouts to collect rains that fall on the rooftops, drains and catchbasins to gather runoffs from downspouts, streets and parking lots, underground storm sewers will then convey all the runoffs and discharge them to a natural water system such as a creek, river and ocean.

There are a couple issues with this.  First, a big chunk of rainwater is lost to runoff.  Rainwater is freshwater that is basically clean in most circumstances, which can be used directly for outdoor purposes, as well as indoor with proper filtering and cleaning.  It falls right on our roof so no transportation is required to receive that water.  However, in the current infrastructure, that much freshwater is sent right away, requiring another huge set of infrastructure to deliver the water we need.

stormwater runoff

Another issue is pollution.  As it flows through the surface of the city, stormwater runoff collects all kinds of pollutants such as motor oil, gas, chemicals, fertilizers, pesticides, etc.  As the stormwater is discharged into nature untreated, it pollutes the water system discharged into. Toxic substances from cars and pesticides can harm birds, fishes and other aquatic life.  Nutrients from the fertilizers can cause the overgrowth of algae, depleting oxygen in waterways and aquatic habitats.

The third issue is insufficient water infiltration for the soil under the impervious cover and in general.  As we can see in the illustration below, in a natural environment (left), 25% of water is infiltrated in shallow surface, and another 25% will percolate deep into the soil.  In a city environment (right), those figures drop down to 10% and 5% respectively, so the water that goes into soil reduces from 50% of total to a mere 15%, a 70% reduction.  The lack of deep infiltration is a big problem.  Without proper recharge, the groundwater is seriously depleted in many places.  As we rely on ground water as part of our water supply, this has a big impact for our water safety.

stormwater comparison

Lastly, waterway erosion and threat of flood.  As a huge amount of water is gathered and discharged into waterway, the volume and speed it packs can erode the banks of the stream or river; when the volume is too heavy, it can flood surrounding areas.

Benefits of capturing and reusing rainwater

People’s thinking about rainwater has completely changed.  Now, rain water is no longer thought as waste; instead, it is viewed as an asset, something we need to capture and reuse.

  • A source of water supply

From 2013-2017, California experienced a historic drought.   At its worst point, the water content in the snowpack was only 5% of normal.  The drought was so severe, it was one of the worst in the state’s history.

California drought

After the drought, everyone realized we could no longer take the water supply as we knew it for granted. With climate change, drought might become more frequent and serious; on another hand, with economic expansion and population growth, our demand for water will just grow.  How can we build the reliable water supply that can meet our needs?

“Stormwater could be a significant addition to California’s water supply. While the potential is still unknown in the Bay Area, Los Angeles estimates that rainfall could provide nearly half a million acre-feet (620 million cubic meters) per year, said Steven Moore, a member of the State Water Resources Control Board. This may sound trivial compared to the 33 million acre-feet people use statewide each year, but it’s not. “Stormwater could make a difference,” Moore said. “It could see us through seven years of drought instead of five.”

From a cost perspective, local stormwater capture is one of the cheapest methods for water supply.  It is only more costly than urban water conservation, but much cheaper than others like recycling and ocean water desalination.

  • Reducing pollution and recharging groundwater

As the importance of rainwater is more thoroughly understood, people have been taking all kinds of steps to keep rainwater instead of letting it flow away.  In the cities, permeable surfaces are replacing the impervious ones, and more and more rain gardens have been built, in the streets, around offices and in our gardens.

When it rains, the rainwater can infiltrate the soil from the permeable surfaces and rain gardens.  In the process, harmful pollutants in the water can be filtered out; the cleaned water can percolate deep in the soil, replenishing groundwater.

Here is a storm drain at a street corner.  The catch basin around it was built into a rain garden, allowing the rain water to sink into the soil.

  • Reducing the threat of erosion and flood

Since water is directed away from the runoff, the total runoff volume will reduce, and the speed and energy that it packs up will lessen.  As a result, the force to erode will be smaller, and threat of flood lower.

SB231

On Oct 6 2017, SB231 was signed into law in California, making it much easier to fund and build rainwater capture projects. The key is the clarification about whether stormwater projects are subject to the exemption of prop 218:

Excerpts from SB231:

The Legislature finds and declares all of the following:

(a) The ongoing, historic drought has made clear that California must invest in a 21st century water management system capable of effectively meeting the economic, social, and environmental needs of the state.

(b) Sufficient and reliable funding to pay for local water projects is necessary to improve the state’s water infrastructure.

(c) Proposition 218 was approved by the voters at the November 5, 1996, statewide general election. Some court interpretations of the law have constrained important tools that local governments need to manage storm water and drainage runoff.

(d) Storm waters are carried off in storm sewers, and careful management is necessary to ensure adequate state water supplies, especially during drought, and to reduce pollution. But a court decision has found storm water subject to the voter-approval provisions of Proposition 218 that apply to property-related fees, preventing many important projects from being built.

….

(h) Proposition 218 exempts sewer and water services from the voter-approval requirement. Sewer and water services are commonly considered to have a broad reach, encompassing the provision of clean water and then addressing the conveyance and treatment of dirty water, whether that water is rendered unclean by coming into contact with sewage or by flowing over the built-out human environment and becoming urban runoff.

(l) The Legislature reaffirms and reiterates that the definition found in Section 230.5 of the Public Utilities Code is the definition of “sewer” or “sewer service” that should be used in the Proposition 218 Omnibus Implementation Act.

With SB231, it is clear that rainwater capture projects do qualify for the Prop 218 exempts, making them much easier to fund and build.

To summarize, facing the ever increasing demand for water and a future with possibly longer and more frequent drought, we now look at stormwater with a completely new perspective.  Gone are the days when we think of it as a waste; instead we know it is a great asset, and will try to capture and reuse it in a way that will benefit us, and the environment the best.

A Tale of Two California Flowers

Everywhere you go, flowers are blossoming!  In the mountains, on the plains,  around the corners of our neighborhood, they offer so much beauty and charm of the nature.  Among them, these two flowers probably catch your eyes quite a lot: the tall Matilija Poppy (Romneya coulteri), and the splendid, golden California Poppy (Eschscholzia californica).  Together, they are a tale of two flowers.

Matilija Poppy

California Poppy

Voting for the State Flower of California

In 1893, the California State Floral Society met to vote on the state flower of California.  There were 3 contenders: the Matilija Poppy, the California Poppy, and Mariposa Lily.  All native to California.

Mariposa Lily
Mariposa Lily

The result: California Poppy received all the votes except for 3, which went to Mariposa Lily.  The California Poppy was determined to be California’s state flower.  A decade later, in 1903, legislature made the title official. Here is a California Scenic Highway sign with the California Poppy.

Two Flowers, Great Plants for a California Friendly Garden

Both Motilija Poppy and California Poppy are beautiful California native plants that are drought tolerant, making them great choices for a water efficient garden.

Matilija Poppy  is native to dry, sunny environments in Southern California and Baja California.  The flower, like a fried egg (“Fried Egg Flower”, another name of Matilija Poppy) is one of the biggest of any species native to California.  The flowers usually begin from early spring and can last until late summer.

Matilija Poppy is tough and very drought tolerant, can survive in most of the soil conditions.  It can grow to be 7 feet tall and 28 feet wide.  If there are some spaces needed to be filled in the garden, the Matilija Poppy can be a good contender.

In this garden, the Matilija Poppies are planted near the window.   When fully grown, they can become a shield for privacy and hot sunlight.

The California Poppy is 4 to 12 inches tall.  They bloom in spring, adding their bright golden or yellow color to any garden. It is drought tolerant and easy to grow. Here, the green foliage and yellow flowers decorate the dry creek bed of this water efficient garden very nicely.

Vote on Your Favorite California Flower

Now you have a chance to vote on your favorite California flower.  These 4 flowers are all California natives. In addition to the Matilija Poppy and California Poppy introduced above, the other two are California Lilac (Cean0thus) and Lupine (Lupinus).  They are all drought tolerant plants great for a California friendly garden.

Which one is your favorite?

Echium: Color and Drama for a Water Efficient Garden

Echium

Want color and drama in a water efficient garden?  Consider Echium. At 6-8 feet tall when fully grown, their big spikes are like flower towers in a garden.  With them in the picture, there is no chance a garden is plain and dull.

Water Efficient Plant

Echium originates from North Africa and nearby islands in Atlantic Ocean. They are well adapted to the climate there, and are drought tolerant.

The type of Echium that we see most often, as in the picture above and below, is called “Purple Tower Echium”.

2016-03-20-15h43m56

Another type we can see is “Tower of Jewels”, which sports pink flowers, instead of the purple blue ones of “Purple Tower Echium”.

Both types are drought tolerant, and qualify for Santa Clara Water District’s Landscape Rebate Program.  Once established, they need only a little water.

2016-03-20-15h43m21

This is another type of Echium, “Pride of Madeira”.  It originates from the island Madeira, off the northwest coast of Africa (Madeira is part of Portugal).

“Pride of Madeira”, in Barcelona, Spain

2016-04-10-10h56m33

Bees’ Favorite Plant

Echium’s flowers attract bees, making it also a great choice for a bee garden.  If you want to build a garden that attract bees, birds and butterflies, this is one of those plants!

Echium_4

Echium_6

Planting 

Echium can grow to be very tall and wide, so plan for a rather big pocket of space.  Plant them in a group, match with other medium and low height plant groups.  The grouping will also make it better for bees if a bee garden is desirable.  The bloom time is from spring to summer.

Full sun is required.  Water until establish, then only very little watering is needed.

So, if you are planning for a water efficient garden, and have quite some space, if you enjoy those bold colors and tall towers, you can choose some “Purple Tower Echium” or “Tower of Jewels”!

10 Drought Tolerant Plants for a Beautiful Garden

Plant18

When I came across this small park in a quiet residential area in Menlo Park, I was amazed by its smart design and selection of plants.  All the plants are not only beautiful, but also native, drought tolerant that qualify for Santa Clara’s District’s Landscape Rebate Program.  This  is a nice garden and park in one,  a place where people can relax and enjoy a quite moment.  It is also a place that we might learn one thing or two when we are thinking about designing our own garden.

The park is designed by Mara Young (landscape architect), and constructed by Janet Bell & Associates.

P2

The park can be thought as comprising of two parts: the main area that is centered around an artificial turf, and the side area.

For the main area, it can further be divided into front, left, center, back and right areas.

P4a

The Front of the Main Area

The main area has two rather wide entrances, one on each side.  The plants between the two entrances serve as a nice low wall for the space.

P6

At the right end of the wall is a nice display of plants, accentuated with a rock.

P8

On the left are three Kangaroo’s Paws, with an orange blossom one in the middle and two green ones on each side.  Behind them are some catmints in purple blossom, and rosemary in a tall green bush.  Together they form this background that the blossom of Kangaroo’s Paws contrast nicely against.  The combo of all the colors  make for a pretty and warm welcome.  In addition, since Kangaroo’s Paw and all other plants are native, drought tolerant ones, by having them as the welcome plants, they make it clear this is a water efficient garden with natural beauty.

P10

On the other end of the wall, it is the same combination – Kangaroo’s Paw against rosemary.  The consistency is a nice touch.

P12

This is the outside view of the wall.   The main body is comprised of rosemary and catmint.  High and low, green and purple: simple yet elegant.

P14

From the inside of the wall, some Lamb’s Ears grow in the middle spot.  The thick leaves add texture; the purple flowers, when it blossoms, are consistent with the color of those for catmint.

P16

Overall, the front of the main area is made up mainly of rosemary and catmint, with Kangaroo’s Paw and Lamb’s Ear as decoration plants.  The major color theme is green, purple and some orange.

The Center and Left of the Main Area

The center area is an open space around an artificial turf.  In this space,  people can take a walk, talk to other people, or walk their dogs.

P18

On the left, there is a small sitting area.  The rocks add a casual feel and mental boundary, while also serving as seats when needed.

P20

Behind the sitting area, the tall bushes of rosemary, Matilija Poppy, Lindheimer Muhly form a wall that blocks out views from the street and neighboring houses and gives the space privacy.   Lamb’s Ear and catmints on the ground add variety.  Here the major color theme is white, light beige and some purple, against the green background.

P22

The Back and Right of the Main Area

This area is a long thin area which is filled out by a couple of big bushes: Large Cape Rush, Lindheimer Muhly, Russian Sage, and Jerusalem Sage.  Each bush sports a different color that makes the space  pretty and fun:  (from left to right) the brown of the Large Cape Rush, the light brown of Lindheimer Muhly , the purple of Russian Sage, Jerusalem Sage (off bloom season), and the orange of the Lion’s Tail.

P24

P26

The Jerusalem Sage is off season now and trimmed down;  couple months ago, when it was in full blossom, it boasted of very pretty and unique yellow flowers, filling  up the space with a lovely view.  Not only is it pretty, the sage is also very drought tolerant and needs very little water.

P28

At that time, the Kangaroo’s Paw and Russion Sage next to it, did not blossom yet;  now they do, what a splendid view!   With these three plants together, there is good blossom to enjoy here at this corner throughout most of the year.

The tall bushes of Lion’s Tail, Russian Sage, Mitilija Popply, Lindheimer Muhly and Feather Grass form a colorful block, rounding out the back of of main area.  The bright organe color of Lion’s Tail rhymes with that of the Kangaroo’s Paw in the front.

The major colors for the back area are brown, purple, yellow, and orange.

P30

The right of the main area is a strip of plants along the right border of the park, decorated with two rocks.  Green bushes provide the backbone of the block, with a splash of color from a Lion’s Tail (orange), Large Cape Rush (brown), lantana (purple) and verbena(purple).  The big white flowers of Mitilija Poppy far back also add to the colors.  Here the color theme are consistent with the other areas: brown, orange, and purple.

P32

The Side Area

This is a long piece of space on the left of the main area.  No park like space here, just a garden.  It is filled with the same native, drought tolerant plants as in the main area: Mitilija Poppy, Feather Grass, Russian Sage and Lion’s Tail.  The pretty blossom of each plant turn a pice of bare land into a beautiful view.

P34

Summary

This is a lovely park and garden in one, a perfect place for the community to take a break and relax.

When I was walking around the park, these things stood out in my mind in terms of design:

The plants: all of them are native, drought tolerant plants, conserving water while providing a beautiful space.

The colors:  the main colors of orange, puple, brown, light beige and white  run across all the different areas of the park with some variations, giving it a consistent yet lively feel.

The shape: No a straight line or corner in the park (except the 2 side borders of the turf);  all lines are framed naturally by the plants, which goes in harmony with the native plants and the “natural” vibe of the park.

Here are the major plants in the garden and their names:

Kangaroo’s Paw: Add Color and Fun to Your Garden

Even if you did not know what a Kangaroo’s Paw (Anigozanthus) looks like, when you see one, you will know instantly that must be it.  Those paws are hard to miss!

Kangaroo's Paw

Kangaroo’s Paw not only has a fun name, but also fun colors – red, golden, green, yellow.  Tall (up to 20 feet), unusual flower structure, nice form with branches, and yes, those bright, pretty colors – all these make it a favorite for gardeners everywhere in the world.

A Drought Tolerant Plant

Even better, Kangaroo’s Paw can thrive with very little water.  Native to South-Western Australia, it is well adapted to the dry desert climate. Once established, it needs very little watering, making it a great plant for any water efficient garden.  It qualifies for Santa Clara Water District Landscape Rebate Program.

There are many ways a Kangaroo’s Paw can be planted in a garden.  It can stand on its own as a center piece, or in a group with other colors of Kangaroo’s Paw.  It can also be planted with other plants, such as green or yellow grasses, to make a good contrast and a nice looking corner or stripe.

A Focal Point of a Garden

A tall, bright colored Kangaroo’s Paw can make a strong statement and become one of the focal points of a garden.  The red paw easily captures one’s attention when one looks at the gardens below.

7 Native Plants Great for Your Garden


7 native plants great for your garden

If you go for a hike in one of the state parks or nature preserves in northern California now, chances are, you will see blossoming wild flowers.  They can be as tall as a tree (Matilija Poppy), or as small as a daisy. Standing with flowers of all the different colors and shapes, they make spring come to life.  Wild flowers under blue sky – one of the most beautiful scenes you can see in nature.

Benefits of Gardening with Native Plants

Native plants are not only beautiful, they are great for gardening.  Adapted to California’s dry and windy environment, they are hardy, strong and can thrive without any care.  There are a lot of benefits of gardening with native plants:

  • Water efficient: these plants do not need that much water; compared to a lawn, a garden with mostly native plants can save a significant amount of water;
  • Low maintenance: they can thrive on their own; no or little care is needed.
  • Attracting butterflies, birds and bees: they sure like the food from the plants that they know well, and you can view them often in addition to the beautiful blossoms.

The native plants below are excellent choices for a garden.  They are all water efficient plants and all qualify for Santa Clara Water District’s Rebate Program.

Matilija Poppy

What does the flower look like to you?  That is right, a fried egg!  Also named Fried Egg Flower, Matilija Poppy (Romneya coulteri) is native to dry, sunny environments in Southern California and Baja California.  The flower is one of the biggest of any species native to California.

Matilija Poppy is very drought tolerant.  It can grow to be 7 feet tall and 28 feet wide.  The flowers usually begin from early spring and can last until late summer.

Jupiter’s Beard (Red Valerian)

At this time of the season, everywhere you go in North Cal – Monterey, South Bay, East Bay, chances are you will see the bright blossom of Jupiter’s Beard, or Red Valerian (Centranthus ruber).  On the streets, in the gardens, at the beach, by the mountain, the pink, crimson and purple colors paint out the picture of spring so vividly.

The Beard of Jupiter

The name must be one of the most unusual for a plant.  Why such a name?  Well, take a look at this statue of Jupiter:

P1

By I, Sailko, CC BY-SA 3.0, https://commons.wikimedia.org/w/index.php?curid=16480594

Look at the shape of his beard!  Here is the introduction of Jupiter on Wikipedia:

“Jupiter, also Jove (LatinIuppiter [ˈjʊppɪtɛr]genIovis [ˈjɔwɪs]), is the god of sky and thunder and king of the gods in Ancient Roman religion and mythology…His identifying implement is the thunderbolt and his primary sacred animal is the eagle”

In addition to the shape, as the king of gods (Roman time), Jupiter’s beard must also be enormous and magnificent, a perfect match for the wonder and splendor of the flower.

P2

While you are taking a break to appreciate the flower, if your kids are also around, it can become some good storytelling time too, about Jupiter and any stories in the Roman mythology.

Water Efficient Plant

Jupiter’s Beard is an excellent plant for a water efficient garden.  Once established, it needs very little to no water.  It qualifies for Santa Clara Water District’s Landscape Rebate Program.

Rockrose – a beautiful drought tolerant perennial from Mediterranean

Beautiful blossom

I planted a rockrose in our garden, in the San Francisco Bay area, about 2 years ago.  Since then, it just remained a quiet small shrub.  All leaves.  No blossom.  Never thought anything about it until a morning in March, after a full day of heavy rain and a pretty heavy rainy season brought by El Nino.

Voila!  flowers!  So it does blossom, after all! Look at those dark pink dots on the pink patals – making the flowers look like small smiling faces!

The rockrose stood proudly with its smiling faces for about a week, then I packed my stuff and left for a trip in Europe.  Before I left the house, I waived it a silent goodbye:  so long, my rockrose!

Rockrose
Rockrose
Same smiling face in Barcelona

The first week in Europe was like a wind whirl, then I landed at Barcelona.  There were so much to see, so much to do.  The day before I left, I went to this big park with other people.   As everyone was just rushing to the entrance, I saw this on the slope along the road:

Rockrose

Rockroses!  So glad I can see you here half the globe away!  The blossom, the leaves….you are truly sisters!  The only difference is this variety does not have the dark pink dots on their petals, nevertheless they smile the same bright smiles in the spring sun. 

A perennial from Mediterrarean

This is what I found on Wikipedia when I searched for the word “rockrose”:

“The Cistaceae are a small family of plants (rock-rose or rock rose family) known for their beautiful shrubs, which are profusely covered by flowers at the time of blossom. This family consists of about 170-200 species in eight genera, distributed primarily in the temperate areas of Europe and the Mediterranean basin, but also found in North America; a limited number of species are found in South America. Most Cistaceae /are subshrubs and low shrubs, and some are herbaceous. They prefer dry and sunny habitats. Cistaceae grow well on poor soils, and many of them are cultivated in gardens.”

No wonder I see rockrose in Barcelona…they come form here!

Plant a rockrose in your garden

Rockrose is a great perennial to have in a water efficient garden.  Beautiful blossom, multiple species and blossom colors to choose from – purple, yellow, white, pink, etc., and needs very little or no water once established.  Rockrose qualifies for landscape rebate programs, such as Santa Clara Water District Landscape Rebate Program.

Rockroses needs full sun, and can grow in almost any soil type.  Water regularly until it establishes, then just leave it there.  It will serve up pretty blossom when the time arrives, just like the ones at my garden.
