Lost Creeks of the Bay Area – Part I

There are a number of cities with a vibrant mix of activities around hidden hydrology, some of which have been covered previously (see Resources). The stories of San Francisco’s hidden hydrology have existed for years, starting perhaps with an account by William Crittenden Sharpsteen of Vanished Waters from 1941, and continuing today with ways to offer hints to the current configuration of odd topographic features like ‘The Wiggle’. There are also references to discovering and possibly daylighting urban streams in San Francisco, even positing what other cities can learn from their relationship with it’s urban creeks.

One of my favorite organizations, SPUR, has an article from 2006 in their archives ‘Of Buried Creeks and Thwarted Plans‘ worth reading, which explores Burnham’s unrealized 1905 Plan for San Francisco which would have created open space in favor of freeways. “Perhaps one of the most remarkable features of the unrealized Burnham Plan would have made Islais Creek the central natural feature of a long linear park stretching from the upper reaches of Glen Canyon all the way to the bay; today the water runs in culverts buried under the bleak interstate freeway, one of the few that overcame citizens’ opposition in the 1950s and ’60s.” Across the Bay the situation is similar, with references to hidden waters of Temescal Creek and it’s potential daylighting, as well as similar efforts in Berkeley to daylight urban creeks.

The San Francisco Bay Area has a number of interesting projects and resources worthy of investigation and emulation, spanning from mapping, artistic interventions, and historical ecology, warranting a couple of posts to capture in total. Here’s a few of them.

Seep City is a project of the local Joel Pomerantz “a writer and natural history educator recognized for his work in waterway research, local journalism, public art and community service”, who also focuses on local urban explorations through the group THINKWALKS. The Seep City was funded by a Kickstarter from early 2015, and is squarely related to the hidden hydrology, as explained on the site. “When San Francisco was first becoming a city, it had many more waterways than now. Those were wet years. When dry years came the gullies became annoyances. People filled in the creeks and low areas with sand, debris and gravel. Marshes and sloughs were filled, too. The edges of the city were expanded into the Bay, making sailable water into salable lots. Today’s rain goes right into sewers, for the most part. Few absorbent soils are still exposed. Remarkably, surface creeks do still flow, here and there. And when you dig, you still find groundwater. If you search you’ll see springs, mostly small, seeping and trickling out onto our landscape.”

The project is explained in a bit more detail in “Mapping San Francisco’s Surprising Abundance of Springs and Streams” in Wired Magazine from 2015. In addition, an older essay in FoundSF entitled ‘San Francisco’s Clean Little Secret’. (originally published in the anthology The Political Edge and published Fall 2004 by City Lights Foundation) At the end of the article, there’s a short disclaimer:

“There is now (2010) very strong evidence surfacing that some of the historical assumptions that calculations and details in this article were based on need to be reinterpreted due to further scholarship. Specifically, although many maps show one, it appears that there was never an enduring freshwater lake in the Mission District. It turns out that “manantial” means spring-fed, rather than merely any freshwater. The waterways in the Mission area were all stream-fed, and Anza’s journals make it clear that “laguna de manantial” was a reference to Washerwoman’s Lagoon (earlier called Laguna Pequeña) in what is now the Marina and Cow Hollow areas. Anza passed this on his way to search for a site for the mission and thus included it in the same description. However it was not in the same geographic area.”

The original essay, linked here, shows some more dialogue on this errata. To me, it’s an interesting journey around the continuing evolution of hidden hydrology, that it is often a continual process of refinement and discovery. Some interesting dialogue as well is included on the origins of Phelp’s Lake. and as explained by Pomerantz, “Of course, my discovery creates other layers of mystery.”

The below map depicts the original coastline, marshes and creeks of San Francisco, in the mid 1800s. Lake shapes varied over time, which explains the difference between this and the detailed Mission map in the article.

Ghost Arroyos is a project that got a fair amount of press (Curbed SF, CityLab) emerged from the Market Street Prototyping Festival and the brainchild of Emily Schlickman and Kristina Loring. From the site: “Hayes Creek, a large underground waterway, is still flowing beneath the streets of San Francisco today. We asked passers-by to look behind them – the water spraying from the United Nations Plaza fountain is from Hayes Creek. Beneath their feet, the BART transit authority runs de-watering pumps to keep the tracks from flooding. Even some buildings around the Civic Center still use Hayes water today. To trace the flow of Hayes, they followed the chalked blue lines as they continued down 7th street. In less than a block, they came to where Hayes Creek historically surfaced into a marsh. There they found a watery sonic surprise.” A map below shows the location of Hayes Creek.

From the original project proposal: “Every city has invisible histories embedded within its landscape. Up until the 19th century, ephemeral streams ran through nearly every valley in San Francisco, channeling rainwater to peripheral tidal estuaries. This project, “Ghost Arroyos” seeks to reveal these forgotten waterways of the city through a simple, but powerful intervention. Situated between 7th and 9th street, the project will mark the historical footprint of the arroyos onto the urban surface through paint or lighting. Visitors to the festival will be invited to trace the path of the waterways while listening to a curated recording of hydrological soundscapes and oral histories.” The visual of a painted streetscape was a evocative invitation to the potential to cue people into this lost creek.

The implementation of the project is early, so looking forward to seeing this evolve. A few photos showing a small scale installation of paint on an intersection. A key part of the project is the audio aspects which are available in situ, through boxes mounted adjacent to the ‘painted’ streets. There’s even a step-by-step breakdown of how to make the speakers via Instructables.

The audio is found here on their site:

San Francisco Estuary Institute has long been a key resource in the region, providing “…scientific support and tools for decision-making and communication through collaborative efforts. We provide independent science to assess and improve the health of the waters, wetlands, wildlife and landscapes of San Francisco Bay, the California Delta and beyond. SFEI’s 50 scientists and experts provide data, technology and tools that empower government, civic and business leaders to create cost-effective solutions for complex environmental issues–from cleaner water and sustainable communities to climate change. We have three primary programs: Clean Water, Resilient Landscapes, and Environmental Informatics.”

My main interest related to the connection between hidden hydrology and historical ecology, which can be defined as synthesizing “…diverse historical records to learn how habitats were distributed and ecological functions were maintained within the native California landscape. Understanding how streams, wetlands, and woodlands were organized along physical gradients helps scientists and managers develop new strategies for more integrated and functional landscape management.” It goes further to explain that “Researchers are increasingly recognizing that restoration and conservation strategies have often been misguided (and unsuccessful) because of a lack of understanding of historical conditions (e.g. Hamilton 1997, Kondolf et al. 2001, Foster and Motzkin 2003, Merritts and Walter 2008). This is particularly true in California, where our cultural memory is short and we have tended to impose concepts appropriate to more humid regions to our Mediterranean and semiarid landscapes (which will become only more so).”

An indicative study comes from the Alameda Creek Historical Ecology Study from 2013, which assesses: “watershed conditions prior to significant Euro-American modification, as a basis for understanding subsequent changes in watershed structure and function, and potential options for future environmental management.” While the mapping involves a cast of many, Robin Grossinger, director of the Resilient Landscapes Project is well known for historic ecology in the bay area, and has written extensively on this, including many articles in SF Bay area.

Aside from reports, there are examples of online resources and studies, such as The Historical Ecology of Miller Creek, which was “…designed to inform residents of the watershed and other interested people about past and present ecological landscapes within the watershed, and how this information might be used to plan for the future. The time frame begins with indigenous land use practices and considers the effects of Euro-American settlement beginning about 200 years ago, continues through the present, and briefly examines the future needs of the watershed. This description is meant to broaden the view of what Miller Creek Watershed could become through science-based planning and careful management. Human induced changes in land use have affected the natural functions and habitats of the Miller Creek watershed. The emerging story foresees ongoing change that would benefit from a comprehensive understanding of the watershed’s history while planning to define and secure essential watershed services for the future.”

OTHER PROJECTS

There are also a number of other urban explorations and art installations worthy of mentioning in brief. These precedents offer some interesting examples of engaging larger communities with hidden rivers and creeks, through bike tours of sewers and regular walking tours of hidden waters.

Some specific examples are summarized below:

One I spotted a few years ago were an interesting series of “tours” that are part geographic and part performance art. Led by artist Chris Sollars, as part of the project Water Shed, which was conducted during Southern Exposure’s Off Shore from 2014, participants walked Islais Creek, Mission Creek, and Yosemite Creek in San Francisco. A summary: ““Tracing the hidden path of Islais Creek, Chris Sollars leads a walk from source to Bay while carrying a rope that references the length of one city block. Beginning in Glen Park Canyon, the group will journey through downtown Glen Park, the Alemany Farm, Alemany Flea Market, a Google bus parking lot and the Southeast Treatment Plant. Stopping at various points along the way, the walk ends in Islais Creek Park to enjoy food and drink gathered along the route. There, participants will be ferried onto and off of Water Shed, a floating shed-like structure.”

There are videos of the walks as well linked from Sollars’ Vimeo site – check one for Yosemite Creek out here.

Yosemite Creek Walk Promo from Chris Sollars on Vimeo.

Across the Bay in Oakland, a project called ‘Creeks Beneath your Feet’ connects residents with hidden hydrology. “Former creeks, now buried in culverts, are memorialized by a series of bronze relief sculptures embedded into sidewalks at locations above these culverts. The pieces portray stepping stones surrounded by native fauna that inhabit the creeks such as Rainbow Trout, Pacific Chorus Frogs, California Newts and dragonflies. Each site features five bronze “stepping stones” inviting the visitor to step across as if crossing a creek.” An article in the East Bay Times provides more info and images, and a map of the locations is found here.

An art installation from Kevin O’Connor from 2012 called “Intimate Strangers: A Ritual for the Buried Creeks of San Francisco” uses hidden creeks as artistic inspiration: “Adding yet another layer to the mystery, massive surges of groundwater, much of it potable, travel continuously just beneath us from related “subartesian” sources that even historically never came fully to the surface. We easily overlook these “creeks” since they have never come into view to receive formal names. My proposal is to place 10 blues pools in a line along the creek bed that runs through Garfield Square. Each pool will be filled with water that I have collected from the buried creeks of San Francisco. The backyard wading pools remind us that there are buried creeks that hold water in many backyard homes in the Mission area.”

Finally, it’s a minor addition, but one map from Rebecca Solnit’s excellent ‘Infinite City: A San Francisco Atlas’ shows the fragment of hidden hydrology in San Francisco. From a review in High Country News: “Third Street Phantom Coast,” for example, is a map of the peninsula’s eastern fringe that depicts a now-forgotten city of ancient shell middens, long-buried streams and concretized serpentine outcrops. It shows how, over the last 150 years, the city’s waterfront expanded as successive layers of landfill were dumped on the tidelands of the Bay. Vanished landmarks from the late 19th and early 20th centuries — the “Tubbs Cordage Company” and the “Site of rancho bear and bull fights,” among others — haunt the rendering.”

Part II of this exploration of the Bay Area focuses on many of the maps and mapping resources.

Poetics of Lost Rivers

Jason Kingcultural, history, language, literature, london, places, streamsLeave a Comment

A diversion from the explorations of precedents of cities, we turn to Swimming To Heaven: London’s Lost Rivers by Iain Sinclair the “british writer, documentarist, film maker, poet, flaneur, metropolitan prophet and urban shaman, keeper of lost cultures and futurologist” I wasn’t sure what to expect, and was pleasantly surprised, as was one of those singular experiences that transcends disciplinary boundaries of urbanist, historical, literary, and hydrological worlds. While the topics is Lost Rivers and exploration of the urban, the meditations on water and experience inform a larger connection with place, history, and language akin to what I reference in the title as ‘Poetics’.

Sinclair starts to explain the motivation early:

“Walking over or alongside the buried rivers of London stitches a form of collective memory in our sides.” (3)

Mentioning a continuing fascination and obsession with the water, Sinclair points out early on where the book derived from. “My neurosis persists: the only ways worth negotiating with this world, while still hoping to connect with the rhythms of the cosmos, are by walking and swimming. Which brings me to the haunting complexity of London’s buried rivers. They’re not lost, not at all. Just because you can’t see a thing, as Ed Dorn points out, doesn’t mean that it’s not there. The rivers continue, hidden and culverted as they might be, to flow through our dreams, fixing the compass of our moods and movements. The Walbrook, the Fleet, the Tyburn, the Westbourne, the Effra, the Neckinger: visible or invisible, they haunt us.” (5)

A Map of London Before the Houses – via @culturaltales

A previous book by Sinclair (which I have not read) is a meditation on his home place, captured in detail in Hackney, That Rose-Red Empire, which referenced again in Lost Rivers, when he mentions,“Hackney, before the coming of the canals and railways, was quite a desirable suburb” (14) and “…all these blessings derived from the existence of a founding river, the Hackney Brook. Now bricked over, made into a sewer, lost to us.” (15)

Sinclair connects this to the lost rivers, “It is not possible to understand the growth and development of Hackney, for example, without registering the presence of that subterranean river, the Hackney Brook” (5-6)

Hackney Brook as lost river thus becomes the inspiration, per Sinclair. “I think we should first of all take on the conceit of the ‘lost’ river as being applicable to the whole of London. How do we define a lost river? Are these simply rivers that have become degraded by exploitation, the excesses of mechanical industry? They are present, certainly, their names coded into the streets, but you’d hardly know that they’re there. Or are we talking about rivers that have disappeared — been culverted — and I think that’s more like it. I the mid-nineteenth century, there was a moment when many inconvenient tributaries were culverted, because we needed to introduce, by way of the civil engineer, Sir Joseph Bazalgette, a very effective sewerage system. A circuit of London’s waste to be washed away, purified, dumped into the Thames.” (15-16)

Workmen culverting Hackney Brook in Mare street (c.1900)

Sinclair laments the path that led to the burial of streams like Hackney Brook, or others throughout London. “The old rivers, with their intensely local benefits and pastoral memory traces, were also deemed anachronistic. Either rivers were of use, for transport or water power, or they were hidden, as carriers of disease and conduits of filth and waste.” Seen as progress, “…a sewage system was a proud Victorian boast of progress, contrived to lift the citizens of this powerful imperial metropolis away from the fetid stinks and oozes of the earlier, louder and stickier city of collisions.” (16) His rivers lost to this modernization, are the “…rivers of memory, of inspiration” (7) and thus derive from the idea that “certain areas of the city have their individual sense of time”. (13) While Hackney Brook is the local place for Sinclair, he posits that “…the most mythologized of London’s lost rivers is the Fleet.” (16)

This is seen throughout history, beginning with Wren’s concept for London post-fire in 1666 could have transformed the city differently, utilizing the River Fleet (now buried) as a Venetian canal.

From another post from Chris Haile expands with an explanation of the plan in more detail: “From the remaining part of Fleet Street which escaped the fire about St. Dunstan’s Church a straight and wide street crosses the valley passing by the south side of Ludgate, and thence in a direct line through the whole City terminating at Tower Hill, but before it descends into the Valley where the Great Sewer [the Fleet, a tributary of the Thames] runs… Passing forward we cross the valley, once sullied with an offensive sewer now beautified with a useful canal, with wharves on each side, passable by as many bridges as streets that cross it.” (from Haile 2/1/14)

The southern reaches of the Fleet, flowing from Holborn Bridge, beneath Fleet Bridge, and into the Thames next to Bridewell Palace (between 1553 and 1559)

Sinclair meditates on this plan – and the brief moment before the opportunity was lost. “There was that moment when Christopher Wren felt that he could initiate, with a revamp of the Fleet, a new Venice, right at the river’s mouth, close to St Paul’s Cathedral: a shining rational city of domes and bridges and splendid public works…. Wren didn’t have CGI futurism as a tool, ersatz utopianism, but he did have drawings that suggested Fleet-as-Venice would be a wonder of the age. Except that every soon, and inevitably, the river was a ditch, a sewage creek crusted with dead dogs.” (22-23) The dichotomy of river as urban canal versus the reality of river as sewer is perhaps the dominant theme of lost rivers, culminating in the Great Stink and the Victorian modernization of municipal sewers, which has Sinclair adds, had the result that finally, “the river was enclosed, sealed over, lost.” (23)

Sinclair also evokes a number of literary figures in the book, asking “What is this affinity of London visionaries, writers and mystics, with living water?”. (7) This includes William Blake, who “…lived close to the Thames, tracking the River Fleet to Hampstead, to visit the Linnells, Blake is making a return to the source. He is swimming uphill, absorbing the potency of a partly submerged stream; one of the arteries of his city. There is a very particular sense of London and its geography. And underlying all of this are torrential lines of verse in the great epic poems and wild waters of inspiration surging, stalling, tumbling over weirs and falls.” (6-7)

Another poet inspired by the Fleet is Aiden Andrew Dun author of the long poem Vale Royal “…registers the accretions of fable associated with what he calls the ‘River of Wells’. Dun tracks the fleet from the seven springs of Kenwood, through Camden Town to Kings Cross. He speaks of a river famous ‘for healing and medicinal waters’.” tapping the deep vein of “…meaning and mythology of the Fleet. In practical terms, he leads walks that he calls ‘river pilgrimages’ through the historic traces of the submerged stream.” (17)

Construction work in 1845 to deepen the sewer carrying the Fleet down Fleet Street

Dun “remind us that the Fleet ‘still runs under Kings Cross today’… ‘As late as the mid-nineteenth century’, he says, ‘it ran on the surface through a green and pleasant land. But south of the Euston Road at this period it was already bricked-over and buried’.” (33)

From Vale Royal:

Kings Cross, dense with angels and

histories / there are cities beneath your

pavements / cities behind your skies. Let

me see! (34)

1854 — The Corporation of London workmen repairing the Fleet sewer, south of Fleet street under the direction of Mr. W. Haywood. The sewers carried 87,000,000 gallon of water daily in 1854. — Image by © CORBIS

Building on the work of Dun and Blake, Sinclair continues to delve into literary ruminations on the lost rivers. He mentions that “Text, under the influence of buried rivers, becomes porous.” (30) which is true of London poets Bill Griffiths and Allen Fisher both of whom “…treat our lost rivers. Both of them track South London streams, in the thick of local particulars, towards and erased history, to emerge in the contemporary world of political opportunism, civic discord.” (37)

From Fisher’s poem Place:

if I take a river to its source / and in the

case of the Falcon Brook / this is 2 springs

/ & follow its course / from head to tail /

to the Thames / I may arrived from at least

three projections / the source in the springs

/ is not the actual source / but the first

visible source / so that if Pound said it /

it is original / this originality has come

because of previous accumulation (39)

Anecdotes abound as well, with diversions on the subterranean sewers in The Third Man, which was set in Vienna where we picture Orson Welles – “flapping overcoat running through picturesque sewers. Welles was not ever keen on going down into the tunnels, so they ended up recording sound effects under London: in the Fleet.” (23)

And a special one I’d love to look at closer, the Black Swine in the Sewers of Hampstead (Beneath the Surface of Victorian Sensationalism) by Thomas Boyle, which “The stream rushes on, now under the pavements, slaughterhouses, prisons, book stalls, down the valley of the Fleet, towards myths of albino hogs in the sludge of dripping subterranean spaces… Legends of animals, escaped from Smithfield, feeding on refuse, living in darkness… It has been said that… Hampstead sewers shelter a monstrous breed of black swine.” (35-36)

The literary and the sensational intersect in the sewers and buried rivers of cities, something that is unlike other books on Lost Rivers that take the approach of tour guide, ecological investigator, or historian. Sinclair: “However contradictory your approach to writing about the city, whether you’re a modernist using conceptual methods of research, combined with walking, bus trips, photography, painting, or whether you’re a traditional poet obedient to strict form, rivers infiltrate your projections as memory strips or teasing songlines.” (39-40)

The dialogue is critical without being overly environmental or sentimental. In his discussions, there are moments when the impact of buried rivers sometimes comes to the surface of the writing.

“When rivers lose their status, spiritually and materially, the land is drained of value.” (52-53)

The loss of value becomes transactional, “Hidden rivers are part of an attempt to found a celestial city above the degraded particulars of the nexus of business and banking.” (25) The cost below for another type of city seen above, the “subterranean streams brooding beneath speculative developments in the new suburbs of the west.” (62-63)

This is where we enter the poetics of Lost Rivers, the book a lovely and dichotomous metaphor of the above and below ground city – the old and the new, that looks at loss yielding “…this vision of hybrid London, rus in urbe, snaking away to source, beyond the reservoirs, parks, spring pools…” (49) while also connecting to “London’s plural nature: city within city, upside-down topography, rivers flowing under the ground, heaven inside the ball of earth.” (37)

Beyond the LA River

Jason Kingcity, ecology, history, landscape, los angeles, maps, places, precedents, streams2 Comments

The typical news story from Los Angeles that often emerges concerning rivers tends to focus on the LA River and it’s future and fate. Countless stories of the latest master plans or rehabilitation efforts, Army Corps efforts, or just plain ire at the fact that Frank Gehry was involved have been flying around for years. One of my favorite takes is documented in the fantastic 2008 publication ‘The Infrastructural City‘, which breaks down LA into a number of systems including a good amount of focus on the River. And while no one would dispute the importance of the river to the city (and to countless movie chase scenes) there is a broad and complex hydrology and at work in the City of Los Angeles.

The folks at LA Creak Freak offer a slightly different and broader take, and while they do offer plenty of discussion on the LA River, they explore some of the other tangents of hidden hydrology. As mentioned in their About summary the site is both “… a way to share information about LA’s historical ecology – the rivers and streams that were once here – and to update people on relevant watery news and events with a mostly local focus…” and “…that we believe our rivers and creeks are vital to our communities and our planet. Though degraded and forgotten, they’re worth saving.” This information and activism role is similar in nature to much of my inspirations, so it was interesting to dig into their site. The main players are landscape architect Jessica Hall and Joe Linton, an artist, author and activist with a long involvement in the community. The site links to maps, stories, resources, and some transcribed interviews as well. It’s somewhat free-form, with a few helpful summaries like ‘getting started‘ and ‘recommendations‘ but like many sites, is chock full of place specific info that you just have to spend time digging in to.

Some of the links led to a map from the Rumsey collection of the topography of Los Angeles from 1880 by William Hammond Hall shows another “Beautiful hand drawn map of the Los Angles-San Bernardino Basin. Pen-and-ink and pencil. Relief shown by hachures. It appears to be a base map on a scale of two miles to an inch, probably preliminary (several of Hall’s notations on the edges indicate corrections needed to the topography) and earlier than the 1888 Report titled “Irrigation in California” that had 15 maps that may have been derived from this map. It may also have served as the base for “Drainage area map to accompany report on irrigation and water supply in California” by Wm. Ham. Hall, State Engineer. (188-?). Hall was a famous engineer who was the first state engineer and was responsible for many of the early state water projects (see California Water Atlas). This map does not have any names drawn in except for a few towns, rivers, or railroads lightly penciled in. All the land divisions and city plats are indicated, with mountains, rivers, railroads, roads, arroyos and shorelines shown.”

A link to a map of the North Branch of the Arroyo Seco offers some commentary on the mapping: “I am fascinated by the messiness of the historical landscape before it was flattened and filled, with water confined to neatly linear paths. There are so many notations mapmakers used to depict the ways water manifested in the historical landscape. William Hammond Hall’s maps go beyond mere notation, into the realm of artistic representation. In contrast, USGS maps of contemporary Los Angeles use a limited and inflexible set of icons to depict water: blue lines for waterways (thin or thick, solid or dashed), and blue amoebas for lakes. Does the simplicity of these icons reflect what we’ve done to our surface water; or has what we’ve done to our surface water reflect our simplistic cultural idea about how a water body is supposed to look like and behave?”

While the USGS maps of modern day (or at least 1975 from above) may have evolved be more more generic, but the old ones had some beauty, as shown here in a map from 1896 snapped from the great USGS Historical Topographic Map Explorer.

I love the scale of the monumentally awesome Historical Creek & Wetlands Map of the lower Lost Angeles River and environs map below shows a range of buried creeks, sandy washes, historic wetlands, as well as existing creeks, concrete channels and drains (key to left) from around 1902. Not sure who was the author of this map although the copyright shows 2003 from North East Trees. The original orientation of the LA River and tributaries is interesting to see, along with the other hydrologic elements and topography. There are a number of other excerpt maps from areas around LA as well.

Obviously the LA River is the major drainage, but there are plenty of tributaries and other side drainage weaving through the urban realm. A Google map created by the LA Creek Freak folks provides a bit more context beyond the main LA River channel, showing historic drainages woven through the City such as Ballona Creek much of which is buried and/or channelized.

A great example of online resource in that same basin is the Ballona Historical Ecology web site, an interactive exploration created by multiple sources including the San Francisco Estuary Institute, Southern California Coastal Water Research Project, and the Santa Monica Bay Foundation, along with CSU Northridge, CSU Chico, and USC. For more information you can also download a report for the project here.

Another link to a map show at the LA Central Library called L.A. Unfolded (awesome idea), which led to some more historical maps shows this gem from the Online Archive of California for a Map of the City of Los Angeles from 1884.

A side trip to Jane Tsong’s Myriad Unnamed Streams is a worthy diversion, with stories and maps focusing on Northeast Los Angeles. Various snippets of water history like “Where the Creeks Ran Underground” offer some place specific notes, maps and history for a small segment of LA around Eagle Rock Creek. This series of key maps shows the area with streams only.

And with the overlay with modern sewer system, “Street map showing storm drains/1888 water courses as mapped by State Engineer William Hammond Hall, overlaid onto modern topographical data. Street, stormdrain and topographical data: Bureau of Engineering.”

Also worth checking out is a Curbed LA story “25 Photos of the Los Angeles River Before It Was Paved in 1938″ shows a different, softer side to the river, such as it meandering near Boyle Heights in the 1880s:

And from 1931, “The then-new Fourth Street Bridge” showing a natural river bed and although channelized, softer edges to the river.

This one, from 1938, indicates the plans for channelization: “Shown is an artist’s sketch which graphically portrays the system of dams, underground storage basins, etc., that were set up by the Los Angeles County engineers to prevent floods and to conserve hitherto wasted rain water for domestic purposes.”

The end came after floods in spring of 1938, as described in a book The Los Angeles River: Its Life, Death, and Possible Rebirth: (Blake Gumprecht, 2001): “The first Los Angeles River projects paid for by the federal government and built under the direction of the U.S. Army Corps of Engineers were completed a few months after the flood. Work was finished in October 1938 on three projects to lower the river’s bed twenty feet, widen its channel and pave its banks for a little over four miles upstream from Elysian Park. Three months later, construction was completed on the first segment of what would eventually be a continuous trapezoidal concrete channel to carry the river from Elysian Park to Long Beach.”

Philly H20

Jason Kingcity, creeks, history, maps, philadelphia, places, precedents, streamsLeave a Comment

One of the most amazing resources I’ve discovered was the website Philly H20. A comprehensive look at creeks and sewers in Philadelphia, don’t let the charmingly anachronistic website style put you off, as the amazing detail and density of info contained therein. The site is done by Adam Levine, the “the local expert on the history of Philadelphia’s rivers, streams, and drainage systems.” A quick into from the site:

It has been my pleasurable challenge, as a consultant to the Philadelphia Water Department (PWD) since 1998, to try to piece together the fascinating history of the city’s many lost streams. PWD has preserved its own collection of historical material, which is a rich source of information, and I have supplemented that base with research in local libraries, historical societies, archives and relevant departments of the city government.

Besides many useful written records, I have uncovered a wide range of graphic material including paintings and drawings, maps and plans, photographs and surveys. This material stretches across the breadth of the city’s long history, since changes were made in the landscape almost as soon as William Penn began building his new city along the Delaware River in 1682. The bottom line is that, over the course of several centuries, most of the city’s surface streams have been channeled underground and incorporated into the city’s 3,000 mile sewer system.

The section From Creek to Sewer provides a bit more explanation, “As in many urban areas, most of Philadelphia’s surface streams, encompassing many square miles of watershed, were systematically obliterated over the course of the city’s development. Diverted into pipes–their valleys leveled with millions of yards of fill and overlaid with a grid of streets–these streams now flow in some of the largest sewers in the city’s 3,000-mile drainage system. In most cases, these projects were designed as combined sewers, carrying raw sewage along with the stream flow and stormwater runoff.”

A sequence of “Historic and modern stream maps created by the Philadelphia Water Department (using data gathered from a variety of sources), to educate the public about the fate of many of the city’s streams.” The first shows the historic streams, not sure of a date but according to the site probably from around the 1700s or prior to significant permanent settlement.

The current maps shows some intact watersheds in outlying zones, but most of the inner core, North Philadelphia with the exception of Tacony and Frankford Creeks, and mostly gone in South and West Philadelphia areas buried.

The overall landscape change is best represented with the composite map with subsurface piping shown in red, highlighting the underground hydrology still at work, but really emphasizing the removal of most of the creeks and streams in the core and replacement of a much more structured system. This is a pretty common map echoed many times around the world through the 1850s to early 1900s.

Levine has linked a number of interesting maps, such as the early sewerage system from 1895 which already shows the manipulation of streams and construction of diversions along with buried creeks. It also shows that the city was using a combination of sewer and combined systems, which was again used in many cities as a cost-effective strategy. I’m struck now just how Levine curates the material, but offers a historical explanation, on the page From Creek to Sewer, of how and why these waterways were degraded and eventually filled. A short excerpt:

“Since it was then standard sewage disposal practice to direct branch sewers downhill into the nearest stream, they knew that even pristine surface streams would become polluted once the areas around them were developed. Culverting the streams before they became polluted was seen as a positive step to protect the public health. In undertaking these projects, the engineers also hoped to reduce the cost of the city’s infrastructure in a number of ways. Sewage, being mostly liquid, flows most cheaply by gravity–pumping it up a slope is expensive in terms of fuel costs, and is only as reliable as the pumping equipment. By placing sewers in the natural stream valleys, the engineers got the gravity flow they needed, and in the process they managed to avoid the high cost of making extensive, deep excavations. Once the valleys were filled in over the newly built pipes–in some stream valleys in Philadelphia, more than 40 feet of fill was used–the cost of building a bridge each time a main street crossed the stream was avoided as well. “

There’s links to even more map sources as well, including the Greater Philadelphia GeoHistory Network, maps and photos at PhillyHistory.org and digitizd maps available as well as the Pennsylvania Spatial Data Access (PASDA) site. Another huge archive of info is curated a the Places in Time: Historical Documentation of Place in Greater Philadelphia site, which one, especially if you’re purview is Philadelphia, could spend a lifetime digging through. These 1890 Noll maps (below) are great, and Levine mentions some of the qualitative reasons. “This particular map interests me because it shows the many creeks that other maps of the period omitted even before the creeks were actually obliterated. I also appreciate the elevation contour lines, and although the datum used is different by several feet from the current datum, the numbers still give a sense of the rise and fall of the terrain. The street grid also seems more realistic than other depictions, in that it ends at the creek valleys and indicates, with dotted lines, a few streets that have been projected but not built.”

One of my favorites was the photograph of this physical topographic model from the 1940s “… which clearly shows the transition from the flatter terrain of the Coastal Plain to the hillier terrain of the Piedmont.”

HISTORICAL GIS

One hidden gem was a report from the USGS Fact Sheet FS–117–00 from October, 2000 on “Mapping Buried Stream Valleys in Philadelphia, Pennsylvania” that outlines a process for mapping streams to identify potential risk zones for subsidence. From the introduction: “Specifically requested were a preliminary evaluation of geologic factors that control recent ground subsidence in the Wissinoming
neighborhood (fig. 1) and recommendations for more comprehensive geologic studies that will be required to design a remediation effort and to delineate other neighborhoods that are potentially at risk.”

The use of historical maps of the stream valleys, specifically 1899 USGS topographic maps generated landscape change diagram. From the report: “Examples from the topographic change map included in USGS Open-File Report 00–224. Areas shaded in yellow and labeled Po have been characterized as possible fill. Areas shaded in red and labeled Pr have been characterized as probable fill. A, Map segment showing historical stream valleys of Wissinoming Creek and Little Tacony Creek. B, Map segment showing historical stream valley of Wingohocking Creek.”

The Philly H20 site is impressive in scope, and it’s clear the passion for history, hydrology, and place that are embedded within. Those in the Philadelphia area interested, this should be the first stop – as much of the legwork required in other cities has been done here. There’s tons more info on this site and the more you dig the more info you find, like an Archive with more exhaustive links to many more historical sources and write-ups of key creeks. One by Levine I perused was this “Frankford Creek Watershed: A historical overview of the Philadelphia section” that had one of the most interesting graphics telling taglines: “A Snake that will be Straighted Out”, indicative of the conversion of streams at the time.

ENDNOTE

Finally, I’d be remiss if I didn’t mention one of the most incredible Philadelphia projects, from the early 1990s. The brainchild of Anne Whiston Spirn when she was at Penn and later through MIT, the West Philadelphia Landscape Project had a “…mission is to restore nature and rebuild community through strategic design, planning, and education projects.” Over the course of 25 years this project provided a unique model for community engagement and urban ecosystem restoration that has permeated others work since.

A focus of the work is Mill Creek, where the project sought “…to demonstrate how to create human settlements that are healthier, economical to build and maintain, more resilient, more beautiful, and more just.” The focused Mill Creek Project investigated hydrology and history with an aim to “…explore how a new curriculum organized around “The Urban Watershed” could combine learning, community development, and water resource management.”

This was some of the first examples of GIS based historical mapping I had seen, and although the tech was early, the impact on me was long-lasting. This is perhaps my first exposure to the concept of historical mapping and urban streams, and I vividly remember reading about it in undergrad and being blow away. I mention it just in passing as a Philly endnote (because it deserves a more complete review as a case study) in greater detail. More on this work to come!

Case: Town Branch Commons – Lexington, Kentucky

Jason Kingcase study, city, creeks, ecology, geology, history, landscape, lexington, outreach, places, precedents, projects, soundscapeLeave a Comment

I had the opportunity to see Kate Orff from SCAPE speak a few weeks back at University of Washington, and it was inspiring to see the mix of project work and activism that is the mark of this creative firm. This project aligns nicely as it is featured in her new book, Toward an Urban Ecology and is another example of ecological design in an urban context. She focused on some of the older projects in her talk, but this is one I’ve been waiting to explore here at Hidden Hydrology, the Town Branch Commons in Lexington, Kentucky.

The project unique example of using the historical hydrology and geology as design inspiration – not a true daylighting but falling somewhere in the middle of the continuum from art to restoration. From Architect’s Newspaper, a recent post SCAPE turns Lexington, Kentucky’s long-buried water into an asset provides a pretty extensive visual overview and some description into the project that complements the overview in the book.

“Town Branch Commons weaves a linear network of public space along the 2.5 mile path of the historic Town Branch creek in downtown Lexington, Kentucky. Once a waste canal, sewer, and water conduit for the city, the buried stream channel of Town Branch is an opportunity to reconnect the city with its Bluegrass identity and build a legacy public space network for the 21^st century. Rather than introducing a single daylit stream channel into the city fabric, the design uses the local limestone (karst) geology as inspiration for a series of pools, pockets, water windows, and stream channels that brings water into the public realm.”

The renderings show the movement of water and the use of stone to embody the conceptual ideas of the Karst geology, which is responsible for the landscape of disappearing and reappearing springs. A more expansive overview of the landscape type from the International Association of Hydrogeologists (IAH) site describes it as: “A landscape formed by the erosion of bedrock, characterized by sinkholes, caves, and underground drainage systems. Many of the surface features are due to underground processes of the weak acids of groundwater dissolving the rock and creating a varied topography.”

This is seen in the design concepts for the spaces that are woven through the corridor, an approach referenced in Toward an Urban Ecology as a ‘Geology as Materiality’ (p.38). The Karst metaphor is incorporated with orderly frames, referencing with geology within a semi-formal urban context that softens the spaces while maintaining functionality. This is where the design-centric approach would differ from the more formal restoration, referencing a key hydro-geological precedent in an urban context. As mentioned in the book ‘Towards an Urban Ecology’: “Town Branch is recast as hybrid hydrological and urban infrastructure, creating defined and safe spaces for water, pedestrians, bicyclists, and vehicles along its path. In the downtown core, streets are realigned to make way for an extended public realm, where water is expressed not at the surface, but underground, as rainwater-fed filtration gardens clean the waters of Town Branch before entering the culvert below.” (p.36)

The concept of the sunken areas allow for an immersive experience within an urban realm. The separation of grade and edges of formal and natural provide variety of experiences that provide a model for ‘daylighting’ and applied urban ecology that is both functional and artistic, aesthetic but with some ecological rigor. As mentioned in A/N: “To create freshwater pools—SCAPE calls them “karst windows,” in reference to similar naturally occurring formations—the design will tap old culverts (essentially large pipes) that previously kept Lexington’s karst water out of sight.“

And more dramatically enveloping in a recreation of the Karst geology and incorporation of moving, dynamic water, while also allowing for physical access to the water, a rare treat in urban areas. This image shows waterfalls near Rupp Arena, a high-visibility area adjacent to more formal plaza spaces at surface.

The nature/culture connection is strong, and a unique model that is about the landscape of Lexington. As mentioned in A/N: “Here it’s all about finding a unique identity framed around a cultural and geological history of a place,” said Gena Wirth, SCAPE design principal. “What’s replicable is the multipurpose infrastructure that unites the city, its story, and its systems.”

Water Walks

An interesting part of the narrative is not just the project design, but the generative strategy used by SCAPE to develop the project. Those already familiar with another SCAPE project, the fantastic Safari 7, (which will get some documentation here soon) will note some similarities of the use of place-based audio and mapping, They documented a public outreach process Town Branch Water Walk which aimed to connect residents to the local landscape. From their site:

“The result, Town Branch Water Walk, is a self-guided tour of downtown Lexington’s formerly hidden water body, Town Branch Creek, with content developed together with University of Kentucky students. The design intervention is not a physical landscape, but a communication tool– using podcasts, maps, and walks for the interpretation of urban systems. The Water Walk gives a broad understanding of the biophysical area around the Town Branch, reveals the invisible waters that run beneath the city, and demonstrates some of the impacts each resident of Lexington can have on the river and its water quality. By sharing how water systems and people are interrelated—both locally and globally—the Town Branch Water Walk makes stormwater quality relevant, linking it with the history, culture, and ecology of the city.”

The walking tour is accompanied by audio that can be used in situ as podcasts, and as more formal walking or bike tours – and this model/map was also used at events along to provide listening stations for the various stories.

There’s more on this process worthy of additional exploration and future posts, and check out the audio and links at www.townbranchwaterwalk.com

Vancouver’s Secret Waterways

Jason Kingcity, creeks, cultural, history, landscape, maps, places, streams, vancouver8 Comments

I stumbled on this map a few years ago, while searching for precedents in the Pacific Northwest for disappeared streams similar to Portland. The image below is a fold out map insert from a book by Sharon Proctor ‘Vancouver’s Old Streams’ (1978), which incorporates streams from 1880-1920.

The hand-drawn quality of the map is a nice touch, with the original shoreline, rivers/streams, and what is called in some cases, ‘Educated guess of waterways’. The description of the map alludes to the varying nature of information and hydrology.

“This map shows the natural drainage of Vancouver, as it was before the City was built. Based on old maps, Archival records and interviews with pioneers, it continually changes as additional sources of information emerge or as people dig new holes in the ground.”

I’m still trying to track down a copy of the book that has the original map, as many I’ve found are missing the map, or only found in libraries. A search yields a link for the Featured Digitization Project at from UBC’s Koerner Library, Vancouver’s Secret Waterways, where Proctor’s map was updated by Paul Lesack in 2011 and available in a new PDF format, as well as GIS shapefiles and Google Map KMZ. A quick summary of the project:

“Vancouver’s vanished streams and waterways can now be seen again in Google Earth, PDF form and other digital formats. UBC Library digitized the content of the Aquarium’s old paper maps, allowing both scholars and the public to see the paths of old streams and the original shoreline of Vancouver. The digitized maps encompass only the area of the City of Vancouver, and show the large area of land reclaimed since the 1880′s.”

The map was subsequently published by the Vancouver Aquarium and although a bit less DIY than Proctor’s original, perhaps easier to read and based on the more recent city grid.

A variation on this comes from the False Creek Watershed Society, created by Bruce Macdonald with drawings and design by Celia Brauer, provides a bit more habitat and cultural context to the story, along similar lines to the Waterlines Project in Seattle, with indigenous villages, flora and fauna, and historical place names. These are available to purchase from FCWS.

The earliest map I’ve found for Vancouver was towards the end of the centry, this one from the Vancouver Archive showing a plan of a relatively developed city “Drawn in 1893 by Allen K. Stuart, pioneer, May 1886, in the City Engineer’s Office, City Hall, Powell Street, where he was Assistant City Engineer” which coincides with the founding on Vancover a few years earlier in 1886 (many decades later than Portland and Seattle, which were formally established closer to the 1850s). Some of the creeks remain, but many are no longer evident, maybe to show the relatively developability of the gridded plan, or due to the fact that they had already been piped.

Also available to tell some of the story are some of the aerial lithographs popularized in most cities in the late 1800s. A black and white version of the Panoramic view of the City of Vancouver, British Columbia, from 1898, shows a view looking south over Burrard Inlet, across the modern downtown towards False Creek and areas south.

The colored version is also available in reasonably detailed high resolution also, which reveals that many of the streams documented on the 1850s map were lost to development within the 40 plus year time-frame when this was published.

Proctor’s map of Vancouver is an interesting example of the disappeared streams concept being investigated back in the 1970s, and makes me think that in many cities, there were probably efforts even earlier by others. Carrying on that tradition and modernizing the maps were a good attempt to reconnect people with place and ecological history. Also, the early plans, surveys and aerial lithographs allow us to connect landscape change over time. They offer a bit more margin of error, since they don’t have the same fidelity of aerial photography was not in continuous practice until well into the 20th Century.

Seattle: The Waterlines Project

Jason Kingcity, creeks, cultural, ecology, history, landscape, language, maps, places, precedents, seattle1 Comment

Many precedents and projects from the around the globe, being slowly populated in the Resources section. These will all get some more in-depth attention, and starting it off locally, I wanted to highlight The Waterlines Project. The ability to ‘Discover and Explore Seattle’s Past Landscapes’ is hosted by the Burke Museum of Natural History and Culture, and offers a densely researched and vibrant picture of the historic cultural and ecology of Seattle prior to the significant engineering that has subsequently taken place.

“Founded on Indian ground by American settlers in 1851, Seattle is one of the most dramatically engineered cities in the United States. Its shorelines have been extended, lagoons filled, hills flattened and rivers re-routed. Built on an active geological fault near a large volcano, Seattle has also been jolted by huge earthquakes, washed by tsunamis, covered by volcanic mud and ash, fluted by glaciers and edged by rising seas.”

The project is historical in nature, using the shorelines as a datum for use and reconfiguration over time, which the creators offer as”an appropriate and compelling framework for viewing the city’s history–one that will engage public audiences and raise themes that are important in American history.” Synthesis of documentary info (maps, photos) alongside oral histories and other archaeological and geological study weaves a mosaic visual that is more accessible to the public.

The main product of the project is the large Waterlines Project Map, which available in a number of places around Seattle, as well as graphic and PDF download on the site. The front illustrates the mid-19th Century landscape, before settlement by non-native peoples, including keyed places that reference Coast Salish terms, many of which are evocative and descriptive of function, such as The Growing Place and Water Falling Over an Edge. The ecology is also evident, with a range of forest, prairie, wetland, rivers and creeks.

There’s also a very faint outline of the modern shoreline, which doesn’t dominate but gives a feel for the adjustment of these Waterlines the significant filling, straightening, and flattening that occurred. This is highly evident in the mouth of the Duwamish River seen below, with the creation of Harbor Island and industrial lands south of downtown, as well as the channelization of the previously bendy river.

The back side of the map shows more information in the form of tours of significant historical stories, such as the lakes, glaciation, and rivers, as well as the original settlement location in current Pioneer Square, which was also an indigenous village named The Crossing Over Place. There’s also a timeline of the most recent 20,000 years of geology and development for a bit of long context.

The background for the map is immense, drawing from the previous work of the the Puget Sound River History Project, and involves multiple disciplines. yet it’s simple and effective, somewhat similar to the Mannahatta 2D visuals. The site offers additional source materials, such as maps, photographs and links to resources. Some interesting juxtaposition occurs when paired with recent aerial photos at similar scale – both as a way to emphasis erasure and addition, but also to show traces of what still remains.

The iterations of time between the two time intervals above are indicative of the Seattle penchant for ‘making land’ (matched in intensity with ‘taking land’ perhaps). The story of the filling of the Duwamish and colonization of tideflats and water from 1875 through 2008 in the series below and reinforces the significant alteration that both radically shifted the ecology of Seattles only river, but also provided land to grow the city and industrial base.

The core team includes Peter Lape, Amir Sheikh, and Donald Fels, and a host of collaborators listed here. While referential, the focus is not on the buried streams and creeks, so my work is complementary and draws much in terms of inspiration and information from this project as well as possible collaborations and resources in Seattle.

For a bit more context surrounding the Little Crossing Over Place, this video made by the team shows the transformation of the Pioneer Square area of Seattle “a bird’s eye glimpse at some of the social, economic, and landscape histories of the neighborhood through time.”

Lost Rivers

Jason Kingcreeks, cultural, ecology, film, maps, places, reviews, streamsLeave a Comment

p9784174_p_v8_aa I finally had a chance to view the Lost Rivers documentary thanks to a co-worker picking up a copy of the DVD. The log line sums it up: “Once upon a time, in almost every city, many rivers flowed. Why did they disappear? How? And could we see them again? This documentary tries to find answers by meeting visionary urban thinkers, activists and artists from around the world.”

The films highlight a bit of the multifarious of the hidden hydrology paradigm, that of the explorers, or ‘drainers’ that crawl through pipes in search of photos, and adventure, cities daylighting streams for economic development, urban archeologists with a penchant for maps and popping manhole covers, and designers proposing integrated strategies for flood control and stormwater management. The common thread of these stories, including Montreal and Toronto in Toronto, European examples in London, Brescia, Italy, and some daylighting projects in both Seoul, South Korea and Yonkers, New York.

“We built our cities on the shores of rivers. Over time we pushed rivers away, out of sight and out of reach. But they’re still there. Hidden, everywhere. And around the world city dwellers are on a quest to reconnect to this lost nature.”

We first meet the explorers, or “drainers”, as they are referenced by Danielle Plamondon, one of these explorers that regularly appears throughout the documentary. All around the world folks don hip waders and backpacks of gear, then crawl, rappel, and slog through sewers. The reasons are varied, some with a bent for history, others for the joy of revealing that which is hidden. The illegality of it is also a draw, moving into these as she mentions in the beginning, of people who know what she does, “They don’t realize how forbidden it is.”

I had the distinct feeling that the adventure/illegal paradigm might be the only draw, and wondered, beyond the thrill, what the point of these explorations would be. Having traced a few creeks, it’s been many years since the desire to crawl through pipes passed my mind, although I have to admit this piqued my curiosity for sure. One creative output was photography of the tunnels – which is excellent and perhaps the only view most people will have of these places. Lost Rivers includes the work of Andrew Emond, exploring Montreal’s Saint Pierre River, which starts as a trickle near a golf course and leads to a subterranean labyrinth. His photographs are pretty amazing, and the documentary features some bonus tracks with more of his art installations.

Beyond the purely adventuresome, the film does delve into the history to a degree, and what better city to do this than London, birthplace of the Industrial Revolution. The rapid development of the city meant that London was one of the first. As described by Tom Bolton, author of London’s Lost Rivers, there are 15-20 buried rivers that used to flow on the surface into the Thames, with around two-thirds of the original tributaries either partially or completely buried.

The rivers grew cities, providing hydropower for mills, inputs for tanneries and manufacturing, clean drinking water for residents, all were the engine of industrial development. The same processes which grew cities also led to the downfall of these waterways, with population growth these creeks and rivers became polluted and often deadly. The ‘Great Stink‘ in London in 1858 caused the city to virtually shut down due to smells, and rampant cholera, which quickly led to the modernization and sanitation of these creeks underground in sewers.

This happened in virtually every city in various forms and expresses itself in many ways today, including basement flooding or sewer backups, or even sinking houses, such as those in Toronto that are located atop the former route of Garrison Creek.

Cities that used creeks to drive industrialization were also quick to close them up for progress. Yonkers, New York took the working Saw Mill River, which is a tributary of the Hudson River, and installed a flume, which was buried under a parking lot. As seen in the photos below, the river was channelized, and then eventually capped and filled, a fate that tens of thousands of urban creeks fell to in the late 19th and early 20th centuries.

Driven by a need for economic development to revitalize downtown, the daylighting of the Saw Mill River was seen not just as an ecological plus, but as an economic driver. Ninety years after it was capped, and at considerable cost, the restoration of the river has restored vitality to a depressed downtown core.

The efforts have also been coupled with habitat plans, and followed by environmental education of school kids, who are helping study the ecological impacts of the restoration, particularly on creating new habitat for the American Eel.

London also has taken an active approach to using the routes of lost rivers to aid in resilience to flood control, which has been estimated to potentially cost billions. The River Quaggy, which had been culverted for over 100 years, and because a testing ground for a green approach to flood protection. By removing concrete, daylighting creeks, and using open space, ecologists were able to restore wetland vegetation in Sudcliff Park, creating an urban natural reserve that provides protection from flood waters now and into the future. An additional 15 kilometers of river restoration is planned in the future.

The film also points to some of the misses, such as the strategies brought forth by designers in Toronto, even back in the mid 1990s, to utilize open space of the former Garrison Creek basin for a similar type of flood control. Unfortunately, what could have been a new nature-based paradigm was not implemented, the city choosing to use more technological engineering approaches such as storage tunnels.

I really appreciated learning about the Brescia Underground, a group of Italian urban drainers that were given the official status as a historical society, where they lead tours of underground rivers and continue to explore the unique history of their place, including Roman-era marble bridges built almost 1000 years ago.

The public nature of their tours is impressive, not just walking along the surface but leading the public down into the guts of the city. As one of the explorers mentions, “in every city we dream of doing this.”

The final project discussed is one known to many, the amazing and controversial Cheonggyecheon River in Seoul, South Korea. In addition to finally learning how to pronounce the name, it was interesting to learn more about the additional history of this project, which removed an urban elevated highway and restored six kilometers of river to the urban center.

The newly restored river has had over 123 million visitors, and is focused both as an ecological and cultural system. This is not however, without some costs to both. In the process of removing the highway and restoring the river, a large number of merchants were displaced, taking a social and economic toll, as they were relocated from their lucrative high-traffic locations to a new spot where they now struggle to make ends meet. In addition, the ecology of the site is artificial, due to the nature of the hydrology, the water needs to be continually recirculated through the system, with over 100 million cubic meters of water per day pumped from the Han River, which expends enormous amounts of electricity. As mentioned in the film, “authenticity and illusion may be blurred, but people are drawn to it.”

The artificiality of the system and displacement aside, there were some appreciable benefits beyond the human. The diversity of wildlife has been documented, and over 800 new species have been welcomed back into this urban ecosystem, which is impressive. The remnants of the highway structures were a nice touch as well, sort of a post-apocalyptic homage to the new, novel ecosystem created from the detritus of the past.

The conundrum of pure natural systems versus pumping and manipulation of hydrological systems is evident in all of these projects, as we will talk often in hidden hydrology, there is a continuum that spans from the abstract and artistic to weaving through the designed and engineered to the opposite poles of the true ecological and hydrological restoration. There’s no perfect answer, between painting a blue line on the surface to painstakingly mimicking the natural reference ecology – all are valid approaches.

This sort of topic lends itself to multiple types of media, and a documentary offers a unique way to delve into the experiential qualities of lost rivers, especially urban explorations and the sights and sounds of nature buried and also that restored. The structure of the film jumped back and forth between multiple narratives, which inevitably . And while there was an ecological narrative and implications of resilience and climate change, these themes were not always evident, which had the good side of not seeming preachy, but also made the film seem to lack some substance and impact about the potential. It didn’t try to gloss over some of the critical elements, like the failure of plans in Toronto, and some of the artificiality and social impact in Seoul,

Because the film was released a few years ago so screenings are a bit scarce, but you can purchase the DVD here. It is also available for academic use so set up a screening at your school… its worth a look.

Now, where’s a big pipe I can crawl into around here… ?

Origin Stories: Disappeared Streams Map

Jason Kingcity, creeks, maps, places, portland, streams1 Comment

Over the next week, I have been outlining some of the inspirations and precedents related to the idea of Hidden Hydrology, with a specific focus on Portland stories, as this project has been shaped and has evolves across many years to it’s present incarnation. One of the main inspirations was the map of ‘Disappeared Streams’ that was produced by Metro. My first encounter with this map was during a presentation at DaVinci Arts middle school, as part of the preliminary planning for what would become their beautiful water garden. At the time I was working with local non-profit Urban Water Works – and the students were showing off many of their water-related side projects, including hand-made flowforms, studies of water movement, and mapping. One student had a GIS application that was showing the disappeared streams – which has stuck in my brain every since. Metro now publishes it in map form – available at the Data Resource Center – along with many other great maps.

As I mentioned there are a few methodological caveats to this map – as it is not a historical representation of actual streams, but looking more specifically at locations of potential water routes. From the map, some of this language:

“Development patterns in the Metro region have historically resulted in piping, culverting, or filling of streams and stream beds. A computer mapping program was used to evaluate the terrain in the region, and to generate areas where major streams (those draining 50+ acres of land) may once have existed. While this does not represent an authoritative analysis, it does visually describe the effects of urbanization on the regions natural systems. This exercise indicates that an estimated 388 miles of previously existing streams are now underground.”

The coding of the map is pretty striking (the choice of ‘blood’ red I think fitting) when viewed as a whole (above) particularly noting the core area of Portland that has been denuded of streams over the course of 150 years (below, closeup of City of Portland), where flatter areas were developed for Eastside residential, and margins on the Willamette filled in for industrial development.

You can also get a close-up view,including the central business district – seen in closeup below. Notice the existing pattern, where streams are kept somewhat intact in the west hillsides (topography being somewhat of an antidote to piping), then quickly buried when they reach the urbanized area. Tanner Creek, one of the hidden streams we will be studying closer, is captured as it originates from the Oregon Zoo and cuts through the northwest corner of downtown.

A relatively simple map that is more evocative than accurate, but does much to reinforce the ideology of what is hidden beneath our developed urban areas. As I mentioned, it has stuck with me (and I’m glad Metro still has these available). One of the stronger and original inspirations for the project, it continues to entertain and inspire investigation into our hidden hydrology.

Origin Stories: David James Duncan

Jason Kingcity, creeks, cultural, language, literature, places, portland, streamsLeave a Comment

duncan_mystory-cover Another inspiration for Hidden Hydrology is the writing of David James Duncan (author of a couple of my favorite books, The River Why and The Brothers K amongst the best). In his book of essays from 2002 entitled ‘My Story as Told by Water‘ Duncan tells some stories with a Portland area spin about his youthful explorations in the area.

The idea of oral histories providing an additional layer to mapping and other on-the-ground study is intriguing, as the narrative is both informative and evocative of what these lost urban waterways meant, and what was lost along with them. Early in his childhood, he mentions growing up on Mount Tabor (the volcanic outgrowth in East Portland – not the biblical version, seen below between downtown and Mt. Hood in the image), and his quote worth discussing hints at the disconnect between the modern city and the natural processes which shape and feed these places:

MtTaborPortlandHood — image via Wikipedia

“My birth-cone’s slopes were drained by tiny seasonal streams, which, like most of the creeks in that industrialized quadrant of Portland, were buried in underground pipes long before I arrived on the scene. … I was born, then, without a watershed. On a planet held together by gravity and fed by rain, a planet whose every creature depends on water and whose every slope works full-time, for eternity, to create creeks and rivers. I was born with neither. The creeks of my birth-cone were invisible, the river from somewhere else entirely.” (p.4)

The water system from early in Portland’s history, was stored at high points like Mount Tabor and piped to surrounding neighborhoods. This shot from 1912 shows one of the reservoirs that are still in operation today (for how long, is a good question).

reservoir-one-south-1912 — image via Vintage Portland

The artificiality of the watershed is evident in Duncan’s discussions, as he makes do with building creeks using the hose and the power of gravity (much to his mothers chagrin) – using with water delivered to reservoirs and coming to his tap, as is common in many cities, from distant locales while burying the remnant hydrology that exists. A map of the water system shows the existing Bull Run watershed in relation to Portland.

Continuing this discussion on Johnson Creek on a youthful visit, showing the degradation of some of the existing waterways that has been occurring for many years. “It was just one of Portland’s dying creeks. Really, one with a much-needed but long-lost Indian name. Johnson Creek was now its anemic title. But it was twenty-six miles long, hence a little too big to bury.” (p.10)

It’s heartening to see the restoration of the creek, which is one of the few to remain on the east side in some natural form, through the work of a number of local groups such as the Johnson Creek Watershed Council, and recently there were reports of dead coho salmon found 15 miles upstream – which is significant as it is the furthest upstream anyone has noticed these species in many years, and a testament to the work on restoration and improvement. Something Duncan would appreciate, no doubt.

While water and rivers was of importance to Duncan, the main driving force for him was fishing – which drove the explorations to the wilds of the city. After leaving Mount Tabor, the family moved further east towards Gresham, and lived for a time on Osborne Road, the future route of I-205. Duncan mentions the lure of possible fishing holes, but the inaccessibility: “A spring a quarter-mile from our new house flowed into a series of backyard trout ponds for neighbors, but these ponds were picture-windowed, guard-dogged, private. The closest fish-inhabited waters to my house, so far as I knew, were the Columbia, three miles due north.” (p.17)

The story continues around the small town of Fairview, under Halsey Street, where Duncan spotted a kid and discovered a hidden world amidst the underbrush: “…the shocking thing, the magical thing, was that he was standing knee-deep in clear, lively creek water. A creek surrounded on all sides by briars so dense I’d never noticed it before.” (p.17) Later in the same spot, he saw a guy catching a trout there “a secret trout stream” and found his new exploration spot, as mentioned “Fairview Creek, it turned out, was five miles long, two-thirds wild, and amazingly full of life.” (p.18) See the location on the far right edge as it interfaces with the Columbia Slough watershed.

Following the course, he found gravel pits headwater at Mud Lake that were stocked rainbow trout, near the Kennel Club, a pond with bullheads, and always adventure in the streams. “In the plunge-pool below the Banfield Freeway culvert, I caught a thirteen-inch Giant Pacific Salamader that stared straight into my eyes, flaring and hissing like something out of Dante Volume one, till I apologized, cut my line and released it.”

The approximate area is interesting to see and compare – although the historical imagery from Google Earth (which is awesome btw) only goes back to 1990, there’s a telling transformation in a twenty year time-span (although still a fair amount of stream left intact with development. I remember this area, as my mother used to live just North of the Salish Ponds Park (south of Halsey) and we took the trails through behind the Target and over into Fairview, which is a real gem and one of those places that, like Duncan, you may walk by many times without realizing it’s there. I’ve highlighted Fairview Creek in Blue.

The denouement to this story of youthful exploration comes after a few years of fishing these urban creeks and streams:

“At six-thirty or so on a rainy April morning, I crept up to a favorite hole, threaded a worm on a hook, prepared to cast – then noticed something impossible: there was no water in the creek. …I began hiking, stunned, downstream. The aquatic insects were gone, barbershop crawdads gone, catfish, carp, perch, crappie, bass, countless sacrificial cutthroats, not just dying, but completely vanished. Feeling sick, I headed the opposte way, hiked the emptied creekbed all the way to the source, and there found the eminently rational cause of the countless killings. Development needs roads and drainfields. Roads and drainfields need gravel. Up in the gravel pits at the Glisan Street headwaters, the creek’s entire flow had been diverted for months in order to fill two gigantic new settling ponds. My favorite teacher was dead.” (p.22)

A case of disappeared streams, captured in a moment of time from someone that was there. The sadness in this loss is palpable, as it isn’t just a line on a map, but a leaving & breathing part of someone – both their history and their essence. This sort of study of writings offers many opportunities for exploration through history, and can reveal much about a place in the past. Combined with oral histories from residents and other qualitative study, it offers a dimension that maps just can’t on their own. Thus looking beyond the map to the history is vital and inspirational going forward.
