[Opening digression: I was just texted an image predicting rainfall for LA for the next few days – it looks like you could get hammered (rainfall-wise – what you do with alcohol I have no predictions for), so this post may seem ironic, misplaced, bad timing? You’ve got a trough heading your way and if it doesn’t keep moving…well let’s just hope that it does. The focus of today’s post is dry-weather flows…]
To those of us who recognize stormdrains (or, some of them) as body-snatched creeks, and who long for a water management approach that would incorporate daylighting or naturalization of concreted waterways and nature-based treatment that doubles as streetside landscaping, floodable parks, greenways, etc., well, prepare to be disappointed. Or enraged? Whichever, it’s a familiar feeling. At least we’re not alone on this.
The City of LA recently issued an IS/MND (Initial Study/Mitigated Negative Declaration) and awarded a contract to start work on diverting low flows from certain stormdrains. The low flows – aka urban slobber in some circles – would be pumped from the storm drains into the sewer system, so that they can be treated for pollutants. From there, like the rest of the region’s wastewater, it either gets discharged into
flood control channels rivers, is infiltrated to groundwater, or reused (such as purple pipe irrigation). So you can see how it closes some loops and ticks some sustainability boxes.

Sorry to keep doing this – but I am writing full time over at Streetsblog L.A., and not much time left over for my extracurricular blogging at LACF. Check out this very Creek Freak article I posted today – about the city of Los Angeles getting close to purchasing Taylor Yard Parcel G2. This is , in my opinion, the single most important restoration site along the 51+miles of the L.A. River. I can remember Lewis MacAdams pushing for this site way back in the 1990s; Melanie Winter championing it for many many years. It looks like there’s a willing seller, and the parcel could be in public ownership, maybe by late 2014. Then, over time, it will be part of a 100+ acre park. Woot Wooooooot!!
The city is seeking public comment – see the SBLA article for details.
Water is a Living Archive: Examining myths of where various urban streams come from: Pt. 1: Kellogg Creek
July 2, 2014 § 3 Comments
Have you ever heard rumors that water in various urban streams in Los Angeles originates in significant part from irrigation runoff?
It’s true that car wash and irrigation runoff are often seen flowing into storm drains. Dry season (summer) is the time these activities are most likely to take place. In the case of the Los Angeles River, a good deal of the river’s dry season flow comes from point source discharges rather than groundwater: one report says this figure is about 80% (Arup, 2011). Point sources include storm drains which convey irrigation runoff and carwash runoff, but also effluent from wastewater treatment plants. Flow data collected in 2000-2001 by Stein and Ackerman (2007) indicated that on the average, half of dry season flow in the Los Angeles River originated as effluent from wastewater treatment plants and half from storm drains.
As Josh Link puts it, the Los Angeles River, the end of pipe destination for a good deal of imported tap water, is effectively a « Read the rest of this entry »

Earlier today, Mayor Garcetti announced U.S. Army Corps of Engineers support for Option 20 – the most ambitious of various USACE projects for L.A. River habitat restoration. For more of the story, including some impromptu Lewis MacAdams poetry, see my article today at Streetsblog Los Angeles.

Recently, I was lucky enough to visit the Cape region of South Africa, a mecca for plant nerds, and during my last couple hours in Capetown, I had the pleasure of visiting the studio of artist/designer, Porky Hefer, maker of suspended tree pods inspired by the nests of local weaver birds.
His studio is in part of a former farm compound in Oranjezicht, a neighborhood on the side of Table Mountain, within walking distance of downtown Capetown. Table Mountain is to Capetown what the Empire State Building is to New York City. It towers above the city with its top often bathed in a cloud. The changing appearance of mountain, light and rolling clouds provides a show I found endlessly inspiring. The mountain itself is even more awe-inspiring in that it is a world renowned center of biodiversity right in the middle of a very cosmopolitan city.
I was charmed by a modest water feature next to the discrete entrance gate to Porky Hefer’s studio. The fountain was labeled with a sign that said ‘Grondwater word hier gebruik.’ Though not running, the fountain was built to feed into a brick-lined rill, and as I walked through the studio compound, I noticed the rill appearing mysteriously in other areas of the compound.
When Porky returned from his appointment, he filled me in on the whole narrative of this water. From the first water fountain, water flows into the rill that I first saw. Then it rounds a corner, runs under a door, through a corridor, and into a brick-lined watering hole from which horses once drank. After offering the animals a drink, it runs down a couple stairs, and fills a small courtyard pool, whose reflective surface picks up the movement of the wind. After this thoughtful pause, it flows through another corridor and under a wall to connected properties, where I supposed there were gardens or orchards to be watered.
I loved the sequential integration of direct streamflow into the daily activity of a farm-turned-studio.
It ends up that springs that flowed from Table Mountain inspired Khoi people to call this area ‘Camissa,’ the ‘place of sweet waters’ (where sweet means drinkable). These springs are the reason Capetown developed here. Oranjezicht springs were among the first sources of water for Capetown. Though most of the springs were eventually routed underground, Table Mountain still supplies 5% of the city’s water. The water of Table Mountain is the source of drinking water at Kirstenbosch National Botanical Gardens, where it is treated with nothing more than ozone.
Reclaim Camissa is an initiative founded by Caron Von Zeil to bring to light and celebrate the Camissa water system. Its poetically named pilot project, Field of Springs, embodies the potential of urban waters to seamlessly bridge utilitarian, ecological, and cultural life. This project was included in Capetown’s successful bid to become World Design Capital for 2014. With Capetown in the design community’s eye, it will be wonderful if this initiative can be brought closer to implementation and inspire visionaries in other cities.
This trip was funded by the Dangermond Travelling Fellowship through the Cal Poly Pomona Department of Landscape Architecture.

As many local creek freaks know, today marks 100 years since William Mulholland presided over the dedication ceremony for the opening of the Los Angeles Aqueduct at the Sylmar Cascades where he famously proclaimed “There it is Mr. Mayor.

As the heat of summer slowly (hopefully) begins to wind down, so too has the second season of the pioneering L.A. River kayak and canoe excursions. The final group dropped into the River this past Sunday, an undoubtedly leisurely paddle between willows and sycamores, shopping carts and plastic bags. The 2012 installment hosted approximately 2,000 participants, an impressive increase from 2011, when the count for the pilot program was 260. The number of outfits operating on the River has also doubled and now includes Paddle the L.A. River (organized by L.A. Conservation Corps, MRCA, The River Project, FoLAR and Urban Semillas) and L.A. River Expeditions (organized by George Wolfe and the San Joaquin River Stewardship Program). I had the pleasure of paddling with both groups as a guest educator (thanks to Melanie Winter and George Wolfe for getting me out there!), a journey every Angeleno within reach of a buoyant non-motorized vessel should be able to experience at least once. « Read the rest of this entry »

This week’s New Yorker magazine cover, dated August 27th 2012, depicts a lush green Manhattan. It’s Times Square; there are tall buildings, green roofs, a waterfall, a river, grazing buffalo, a canoe, a horse, people sitting around. To me, it kind of looks kind of like paradise – a city in harmony with nature. « Read the rest of this entry »
