Our travels to Greece this summer for a conference on the Mediterranean City 2014: Adaptation Strategies to Global Environmental Change allowed us to explore the similarities and differences between “The Mediterranean” and Los Angeles, which shares the same climate. Follow the link below for an account of the conference by Laurel Hunt, who interned at Council for Watershed Health last year. Of course, cats are everywhere. This kitty was hanging out at our lunch place.
At Council for Watershed Health, we use design thinking most visibly in our Water Augmentation research and demonstration program. In the research phase, from 2000 to about 2008, we followed the design thinking steps empathize, define, and ideate as we sought to understand and reimagine how improved storm water management could be the key to achieving multiple benefits, including flood risk reduction, water supply, water quality, and community improvement. The demonstration at Elmer Avenue and Paseo is our prototype – and what we learned from Elmer Avenue was used to improve the design at the Paseo. Now we monitor – test – and keep ourselves open to data that will inform future designs – revise.
As the author Theresa Reid says – I can attest this is true – “Design thinking is a messy process that requires stamina, perseverance, creativity, tolerance for ambiguity and uncertainty, and openness to the experience of others.”
It’s no surprise but always gratifying when a major study confirms something we’ve suspected – that living near an urban river parkway improves health. A new review of the research by Dr. Richard Jackson and coauthors concludes that river parkways in cities can improve physical, mental, and community health.
Just reading about the negative health effects of inactivity caused me to get up out of my chair for some much needed stretching. It was hard to stay seated as I read the rest of the report, given the dire health consequences outlined.
The cost of inactivity? $622 per person annually in medical costs.
The construction and maintenance cost per user of a riverfront trail? $235 annually
Another study concluded that “every $1 invested in trails for physical activity led to $2.94 in direct medical benefit.”
And so-called “green exercise,” or simply exercising outdoors, appears to confer additional mental health benefits. Being near water was found to be even more beneficial.
Don’t we all need a little mental health pick-me-up after a long, stressful day at work? I guess I need to swap an hour of reading for an hour of hiking from now on!
There’s too much in this study to summarize all of it in this blog – I highly recommend you set aside an hour to absorb its findings (perhaps while walking on a treadmill). The study provides more support for completing an LA River Greenway and adding trails – walking, biking, equestrian – wherever it makes sense to give people alternate, active means to get to work and encourage movement.
To end this post, here is a photo of the Eisbach, a small man-made river in Munich, Germany. All throughout the day, people line up for a chance to ride this standing wave. Wouldn’t you like to have something like this here in LA?
It’s now been over a year since the completion of the Elmer Paseo, a new, walkable alleyway that is designed to help water to soak into the aquifer. Even during the drought, the Paseo has weathered several storms, allowing us to test the system. The good news is that it is performing very well!
Our researchers documented the Paseo during construction and over the past year. Lots of people, including students from Sun Valley Middle School, have been enjoying their new Paseo.
The plant life, which is native to the Sun Valley Watershed, plays an important role in indicating the amount of water (or lack thereof) moving through the Paseo. The return of rain was a welcome restorative.
The monitoring equipment in the Paseo and on Elmer Avenue are allowing us to gather data on water quantity and quality to better understand how the project is performing. We just took our first samples from the lysimeter beneath Elmer Avenue, thanks to the recent storm. This lysimeter was installed with help from the Water Replenishment District of Southern California. We’re testing the quality of the water that we’re putting in the San Fernando groundwater basin. The data will help us understand the success of the treatment train.
All combined, including additional improvements, the projects are designed to treat stormwater from 60 acres and capture as much as 40 acre-feet of water in an average rainfall year.
Many people have toured the award-winning green infrastructure project, Elmer Avenue Neighborhood Retrofit, and Elmer Paseo. If you would like a tour of these projects, please add your contact information here.

It boggles the mind to think that the Colorado River has been shut down for rafting. Can you imagine if water delivery was shutdown?
Imagine if the tap was turned off to California, Nevada, New Mexico, and Arizona. We aren’t there yet, but the situation inched a bit closer in August when the Bureau of Reclamation announced they would be reducing releases from Lake Powell to Lake Mead to historically low levels. Take a look at the astonishing photos on the Weather.Com website, especially photos 14 and 15 in the slide show series, if you want to understand the magnitude of the situation.
We had a severe drought last in 2002; back then researchers were starting to understand that the West has seen mega-droughts before. If you believe that history can illuminate the present, you might want to read Craig Child’s book, House of Rain, as he takes us on a journey through pre-history on the Colorado plateau to explore some possible answers to the fate of the people who lived here before us and how long-term droughts changed their lives forever. It’s a sobering story.
In a month of some truly depressing news about the environment and climate change, a bright spot appeared. But first, here are two illustrations of the trouble we are in.
In early April, we read that the Arctic may be completely free of summer-time sea ice within a decade, as this graphic cleverly illustrates:
The reason for the Artic Sea Ice Death Spiral is apparent when you look at the continuing upwards march of atmospheric carbon dioxide levels, as reported in early May by Andrew Revkin.
Truly depressing news, eh? Is anybody listening? Are we all doomed? It’s time for some good news, something that gives a little bit of hope.
Apparently, young people don’t drive as much, anymore; the bloom is off American’s love affair with cars and this can only be a good thing. Researchers believe this is a stable, long-term reduction in miles driven that started in 2005, before the beginning of the Great Recession. People age 16 – 34 have reduced average miles driven by 23% from the 2005 peak. Even higher income young people are driving less, evidence that this is a behavioral choice unrelated to the cost of gas.
We can only hope for more good news as the world changes.
