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.

Over the past few weeks, I’ve been dialoguing via email with a fellow creekfreak about the location of Arroyo San Pascual, which was/is in the Pasadena/San Marino/Alhambra area. I thought I’d post the maps that explain this location so that everyone can enjoy the info. For those wishing to cut to the chase – Arroyo San Pascual is the westernmost of the creeks, joining with Mill Creek to create Mission Creek (aka, I believe, Alhambra Wash) further downstream. To the east are smaller creeks, including one that once fed the pond (Kewen Lake) that has since been filled for, um, lawn, at Lacy Park in San Marino. Jane Tsong covered the topic of the arroyos and fascinating geology of this area in depth (here 1, 2) – so I’m going to stick to the maps.
To the left, a federal survey from 1870 which actually gave us some creek names. (when I have a moment I’ll scan and post the entire survey so you can see the rest) To the right, a screen shot of the creek layer I created several years back in GIS, which when imported as kmz files in GoogleEarth has a standing flaw of being offset slightly. The discerning eye can see echoes of the historical streams in the treelines, shadows of terrain, (in)convenient siting of ball fields… correlation of course not being causation. The arrows are meant to call that out for you, imagine those blue lines shifted slightly to the left. Happy creekfreaking, if you get inspired to tour to the topography, let us know what you find out!

As part of coursework for Dr. Susan Mulley’s Research Methods seminar in the graduate program in Landscape Architecture at Cal Poly Pomona, Hieu Nguyen chose to examine landscape changes to the Arroyo Seco through the technique of repeat photography. By comparing historical photographs to contemporary views taken from the same location, Nguyen hoped to detect changes in the parkway landscape throughout the years. “I was mainly looking for vegetation changes, urban development, physical deterioration, and obstructed viewsheds.”
Nguyen had treated the Arroyo Seco in a previous Urban Planning project, and was drawn to the topic again because of “the history, design, and uniqueness of the parkway’s scenery.”
Narrowing down available historical photographs to 10-15 that could be feasibly be physically located, Nguyen headed into the field. But things did not go quite as expected. Nguyen’s narrative offers a poignant view at how physical access to the arroyo has changed:
During the trip, I found out that I could not locate all of the camera angles that I intended to shoot due to the urban development, fencing, private properties, etc. For one photo, the walkway was so narrow, I had to grab onto the handrail on the bridge to keep myself balanced while I was taking the photo as the cars were passing by me at 40-50 mph.
For another photo, I had to climb down the Arroyo Seco Channel to get the camera angle that I wanted. However, I was not satisfied with the angle and wanted to take it from the other side of the shallow running water way. So I tried to jump across, almost slipped and got myself all wet from knee down. But when I went home and overlaid the historical photo and the current photo, I realized that the current angle was incorrect because the channel bed today was much lower than the historical one due to the flood management and channelization of the Arroyo Seco (Fig 4a).
One of my biggest disappointments was finding a lot of chain link fences on the bridges along the parkway. Because most of my camera shots were taken from the bridges, most of the photos were obstructed by the fences (Fig. 1a). Nonetheless, my professor, Dr. Susan Mulley, and classmates all agreed that the fences were significant landscape changes to the grand viewshed of the originally designed parkway and an important part of my research analysis.
Just as starkly, the historical photographs themselves show a channel that was anything but pristine. Creek Freak co-founder Jessica Hall notes that the Arroyo Seco was once characterized as a shallow and broad river. But even the earliest of the historical photos above already show levees and other substantial encroachments onto the Arroyo’s broad floodplain, which confine flow to a narrowed and deepened channel.
Such encroachments suggest that channelization did not happen in one fell swoop– attempts to control the flow of winter stormwater dated from the beginning of development in the Los Angeles basin and intensified with the changes in stormwater flow regime wrought by devegetation and proliferation of impermeable surfaces. The Army Corp’s famous post-1938 feats of flood control are merely the culmination of this history of efforts at confinement. The final result– a smooth and clean channel so conveniently free of vegetation or anything that might obstruct the swiftest flow of precipitation toward the sea. Gone is the disorderly seasonal dynamism of the original floodplain connecting the foothills to the coast. Channelization creates a streambed as neat as a conveniently placed pipe. One might imagine that streamflow originates from a magical tap in the foothills, rather than from the seeping of precipitation into the soil, and its slow under- and aboveground migration to the sea, which happens to leave in its wake a messy mosaic of vegetation and wildlife habitat.
Nguyen’s photographs also illustrate how armoring of banks with concrete did more than just alter hydrology and habitat. Channelization thoroughly severs any natural functional relationship between various parts of the larger watershed — literally paving the way to the radically featureless flat urban landscape we know today.

A recent article in the society pages of Vanity Fair details the woes of property owners along Broad Beach in Malibu, where the narrowing of a beach by 60 feet over the last decade has alarmed wealthy residents. Property owners built a 13-foot high stone revetment wall to protect their houses. Now, they are planning to spend $20 million out of their own pockets to import 600,000 cubic yards of sand, hoping to widen the beach by 100 feet.
Apparently even the residents understand the addition of sand (“beach nourishment”) is at best a temporary solution. To maintain the width of the artificial beach, nourishment would have to be supplemented every 5-10 years—a cosmetic solution that JPL climatologist Bill Patzert called “botoxing the beach.” (Cohan and Grigoriadis 2013)
Nor are revetment walls a real solution. Though they appear to protect property immediately behind them, they actually reflect wave energy to other parts of the coast, where erosion is then accelerated.
Some attribute the erosion of Broad Beach to winter storms. Impending sea level rise certainly will not help. « Read the rest of this entry »
