Creekfreaks! If you, like me, have resolved to pull away a bit from the netflix-amazonprime-hulu bingefests that serve as a daily nonpharma escapist (are we really living these political times?) opiate, and if maybe you, like me, are rediscovering those magical things called books – then I have a few reads for you! They range from practical, to lyrical, to celebratory. Personally, I find them all inspirational. In today’s post, I give you –
The Practical: Restoring Neighborhood Streams; Planning, Design, and Construction
Restoring Neighborhood Streams; Planning, Design, and Construction (2016, Island Press), builds on author A.L. Riley’s decades of engagement and effort in the restoring and daylighting of streams in urban and suburban areas. This Creekfreak was especially influenced by Riley and her work. Her previous book, Restoring Streams in Cities, is well dog-eared in my library, and has been an important go-to reference for how to think about stream function and restoration design. This new book provides case studies that illuminate fundamental questions that should be the basis for planning and design of urban stream restoration:
- Is it physically feasible to restore?
- Is it financially feasible?
- Does the public support (I’d add: political will) exist to support land use changes to support a live river or stream?

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.

The city of Los Angeles is proceeding with demolition of the historic Riverside-Figueroa Bridge over the L.A. River. I’ve been covering this story over at Streetsblog Los Angeles, see today’s article featuring sad photographs showing the bridge being torn up. It makes me sad that this neighborhood-scale bridge is being torn down in favor of a freeway-scale bridge. In this earlier post, I called the project “nothing but zombie engineers fulfilling a now obsolete paean to the automobile.” I don’t think I can outdo that characterization today.
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.

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 »

A couple weeks ago, I got a chance to bicycle a few miles of the Bronx River. It’s not unlike the Los Angeles River: a very urban, relatively industrialized freshwater river, in the process of making a dramatic comeback – with new parks and bike paths along its degraded banks. « Read the rest of this entry »
