Lost Waterways of Dublin

Jason Kingcity, creeks, Dublin, explorations, history, maps, places, precedents, rivers, streams5 Comments

Dublin is another city with a rich history of lost waterways, so as a quick follow-up to the previous post about Belfast, let’s keep the focus on Ireland for a bit longer. The best source for this is a great article by Arron Henderson, “The Poddle and Dublin’s Hidden Rivers“, which mentions that there were over 60 watercourses flowing at one time. While a few remain such as the Liffey, Dodder, Santry, and Tolka – most are either completely gone or mostly underground. Henderson focuses on the Poddle, “…which runs underground for the majority of its course.”

The Poddle flows under Bridge and over a Weir at Mount Argus (via Dublin)

He points of the importance of these hidden streams, and how learning about them can connect with the history of places, sometimes in the margins, and often long erased from memory.

“It’s clear the Poddle played a crucial role in shaping Dublin’s history over so many hundreds of years. Providing our drinking water, powering mills, providing water for brewing, tanning, distilling and market gardens. This explains why, once they learn about it, people tend to treat this modest little river with interest and affection. An affection which is, after all, no more than it deserves.”

As mentioned in the article, there are many other hidden rivers, including the Swan, and place names emerge, with stories about the shopping center named after Rathmines, one of the tributaries of the Swan. Also some etymology, like the suffix “-iken” which means small, and one of Dublin’s rivers named in homage of another larger river named the Nanny, becoming it’s smaller namesake, the Naniken River.

For some exploration, there’s a map that I found, but can’t figure out the author, showing “dublin river past present and culverted“. A snapshot of the map is here, but it’s explorable via the Google map. Many of the waterways are untitled (and perhaps unnamed), but some are identified. Let me know if anyone knows the creator of this one.

These buried streams emerge during construction such as this view of the Swan River on Mount Pleasant Avenue and the old brickwork vaulting.

Similarly, this leads to opportunities for students to explore and learn about these hidden local waterways, as shown in this story from Dublin People, “Students explore hidden Northside waterways” and The National Neighborhood efforts to connect school kids to this hidden hydrological history. ” Led by artist Claire Halpin, the students are investigating the hidden rivers of Finglas and the Tolka river valley, and with the help of the National Museum of Ireland Collins’ Barracks Education team, are getting a chance to see first hand how their ancestors got around on the waters of north-west Dublin. “

“Already they have been learning about the secret underground river, Finglas Wood Stream, which flows right beneath their school. “

For further exploration and information, this video from Urban Tales RTÉ One has a good story about Dublin’s Hidden Rivers, covering the history of the rivers, mapping, and even a little subterranean exploration. Worth a watch.

Anne Whiston Spirn’s Legacy in Philadelphia

Jason Kingcase study, city, climate, creeks, cultural, design, ecology, history, infrastructure, landscape, maps, philadelphia, places, precedents, streams, watershedsLeave a Comment

The most recent October issue of Landscape Architecture Magazine (LAM) has a great story on hidden hydrology inspiration Anne Whiston Spirn, FASLA, titled Where the Water Was, which highlights the “long arc” her work in West Philadelphia, namely the “water that flows beneath it.”

The aha moment is recounted in the article, the inspiration for the poem linked above “The Yellowwood and the Forgotten Creek“, as recounted in the article, she “was on her way to the supermarket, when she was stopped at a gaping hole where the street had caved in over the Mill Creek sewer. “I looked down and saw this big, brown rushing river, and all this masonry that had fallen in. I thought, ‘My God, there are rivers underground. We’re walking on a river.'” (122) Sprin’s work spans decades since that story in 1971, predominately around Mill Creek which was “buried in the brick sewer pipe in the 1880s”, morphing into the West Philadelphia Landscape Project (WPLP) [covered in brief on our post on Philadelphia here]. While I was inspired as a student and professional by her work on books like The Landscape of Landscape and The Granite Garden, her work on hidden streams was perhaps the most powerful for me, both as an object of study but more broadly to leverage this research into a vehicle for positive change. As mentioned, the WPLP website “contains maps, historical documents, reports and studies.” including an updated interactive timeline, and some newer updated interactive mapping which is good to see, as much of the interface until late was a bit dated.

A long way from the preliminary maps in CAD as part of the early mapping in the late 1980s and early 1990s. The sophistication and breadth of this work at the time is telling thought, and I remember seeing these for the first time in college and being amazed. The article shows what many of us know, which is how much of what we take for granted in technology of mapping that’s available to us today, and how hard it was, physically and sometimes politically to get good information. As Spirn mentions “You had to literally go out and field check.” (134)

The takeaways of this early work was to both connect the above ground with what was underground, both historically in predevelopment hydrology but also with sewer routing and burial of waterways. As mentioned, the idea that is a constant with Spirn of “reading the landscape” was instilled as a way to understand the full picture of a site or district. The connection of the physical features with the social is also evident as Spirn is quoted: “It’s a pattern of eastern old cities and across the U.S., where lower-income folks are living in the bottomlands… Many are literally called the Black Bottom.” (126) From this analysis, the idea of mapping and using vacant lands was a way to solve the hydrological problems of flooding or sinkholes, but also to revitalize communities.

The Buried River from Anne Whiston Spirn on Vimeo.

How to do it was an issue, as recounted in the article, ideas where one thing, but changing minds into action was another. McHarg’s Design With Nature inspired her writing The Granite Garden, not as an academic treatise, but rather “…to fill a void. Scientific journals, historical documents, topographic maps, all sorts of materials contained a wealth of information for ecological designers, but no one had pulled it together in a comprehensive, understandable book that could guide designers as well as the public.” (127) This book influences generations of landscape architects in many ways beyond merely historical ecology, but in how we think and communicate. For the project itself, Adam Levine (who is the mind behind the PhillyH20 project which i documented previously) found the 19th Century maps “that showed Mill Creek and its tributaries before the land was developed. Spirn’s students digitized those surveys and overlaid them on the city’s topographic maps, finally getting an accurate depth of fill along the floodplain. “We found it’s buried up to 40 feet in some areas…”” (134)

The actions were part of this research as well, and many interesting strategies came from the Vacant Lands report (see here), as well as a number of other projects, many of which took a long time to become reality, or came with ups and downs of poor implementation or. The successes came, owing to the persistence of Spirn and her local compatriots in West Philadelphia, summed up in the article simply:

“Change is a bit like a buried creek. It’s hard to remember its origins. Its many branchings are invisible.” (137)

The legacy locally is a series of activists still working on landscape and community building. Beyond that, there’s an army of landscape architects inspired by this project and her writings, and her life-long spirit of advocacy. A great homage to a wonderful teacher and landscape hero. Lots of great info in the article – which unfortunately isn’t available digitally at this time.

Geoarchaeology and Lost Rivers

Jason Kingarchaeology, city, creeks, geology, history, landscape, london, maps, places, precedents, research, riversLeave a Comment

Our understanding on the arc of history around hidden hydrology is informed with maps and accounts from early explorers and settlers to areas, augmented with records, diaries, and oral histories. Often this neglects and misses the valuable stories of indigenous inhabitants of areas, and leaves us with a significantly shorter timelines for reference. The role of archaeology is vital to unlocking the layers of hidden hydrology that don’t emerge from these illustrative written histories, so I was really intrigued with a recent tweet from the Museum of London Archaology (MOLA) (Twitter: @MOLArchaology) that told of their current work, called London’s lost river: the Tyburn. From their site, the project is the result of “…a team of expert geoarchaeologists whose work is helping us to understand London’s lost rivers. As an educational charity, we want to share what we’ve learnt, so please join us to explore the story of this long-lost river.”

Using the interactive ESRI Story Map, MOLA developed a narrative to describe the process and some of the key findings. Much of the work is conducted along with construction sites, which gives an opportunity to look below the surface while excavation is happening. The River Tyburn flowed on the north bank of the Thames, and most famously, was routed and defined the space called Thorney that Westminster Abbey was located, seen in this view circa 1530.

The origins of the river are tied to the longer history of the Thames, which is illustrated (see header image) and reaches back to the last glacial period of 11,500 years ago. From there in, “…this new epoch, known as the Holocene, the Thames began to take the shape we know today, but many channels still criss-crossed the river’s floodplain within the wide gravelly valley. One of these channels was the Tyburn, which flowed into the Thames.” In this zone, there are hundreds of sites, or ‘deposit logs’ that are recorded, and these are modelled to create a snapshot, particularly focusing on the depths of land (depicted below as green – high ground and purple – low ground. From this model, “projected possible courses for the River Tyburn, following the lowest-lying areas of the modelled 11,500-year-old topography.” with a caveat that “the river would have migrated over time.”

Drilling down (literally) into the specificity of the deposits shows the ranges of material and how it can inform, looking at “ancient flora and fauna” and focusing on things like Diatoms, Pollen, and fossils of things like “Ostracods, the remains of small crustaceans, can indicate salinity, water depth, temperature, water acidity/alkalinity”.

Below is “…a cross section, or transect, running north–south from Westminster to Vauxhall Bridge, along the north bank of the Thames. This connects deposit sequences recorded in trenches and boreholes, and helps us look at these sequences over wide areas.”

They also connect their study with the work of Barton and Myers 2016 book ‘The Lost Rivers of London‘ (see here for a post on the same), which speculated on a number of scenarios for the Tyburn, and various routes. There’s some graphic things I’d change here (namely it’s hard to read the Barton and Myers layers) but the concept is interesting, to overlay varying studies and ‘proof’ the concepts of routing. In essence, does the data reflect the speculation on routes, either reinforcing or disputing what was speculated? The below map is a composite of this

There’s links to some coverage in London Archaeologist, such as a 2014 article in which “… Tatton-Brown and Donovan used historic documents and maps to suggest that the medieval waterways separating Thorney Island from Westminster were man-made and that the Vauxhall Bridge route was the original and only course of the river.” The 3D views of the route and the illustration of the provide a speculative view of the area. From the site: “Our topographic model supports Barton and Myers’s suggestion that discussing two distinct branches (towards Westminster and towards Vauxhall Bridge) is an over-simplification of what was probably a more complex delta-like network, as shown [below] (artist Faith Vardy). This geoarchaeological study provides a baseline for reconstructing the evolving landscape; when combined with historical records and archaeology, even more detailed models could be created. The research done by others, such as Tatton-Brown, which focuses on later periods, may be supported by geoarchaeological work undertaken in the future.”

The concept of geoarchaeology is pretty fascinating as well, and worthy of some further exploration. In the interim, you can check out the MOLA site for what their team does, which focuses on using “…auger or borehole surveys and interpret the archaeological soils and sediments retrieved, allowing us to reconstruct past landscapes and environments.” The reason for this particular subset is to pick up “…where the archaeology is too deeply buried for traditional excavation techniques to succeed. It is also a cost-effective archaeological evaluation tool and geoarchaeological deposit modelling, which maps buried landscapes and deposits.” This is relevant as the surface remnants of these, but the underground deposits, so they work in a “…wide range of depositional environments, including alluvial floodplains, fluvial environments and estuarine/intertidal zones. Using palaeo-environmental proxy indicators, such as pollen and diatoms, we reconstruct past environments. Our specialists also use a range of sedimentological techniques.”

These techniques don’t answer every questions, but coupled with expertise and interdisciplinary research, enables us to see further, and deeper than previousl. The role of archaeology and geoarchaeology in hidden hydrology is vital, as shown above. While we often rely on maps, photos, sketches, and written histories to reconstruct places,

Atlas for the End of the World

Jason Kingcase study, history, landscape, maps, parks, photography, places, precedents, researchLeave a Comment

The Atlas for the End of the World is a great model for a compendium of research and mapping on a focused topic, which has relevance to my endeavor here at Hidden Hydrology. While the content, scale and goals are different, the structure of information in the format of the ‘atlas’ and the combination of mapping, data, and critical inquiry through essay all resonate as a great precedent.

The project was conceived by Richard Weller from The University of Pennsylvania (UPenn), with collaborators Claire Hoch and Chieh Huang. A summary of the project, launching in 2017, comes from the site:

“Coming almost 450 years after the world’s first Atlas, this Atlas for the End of the World audits the status of land use and urbanization in the most critically endangered bioregions on Earth. It does so, firstly, by measuring the quantity of protected area across the world’s 36 biodiversity hotspots in comparison to United Nation’s 2020 targets; and secondly, by identifying where future urban growth in these territories is on a collision course with endangered species. By bringing urbanization and conservation together in the same study, the essays, maps, data, and artwork in this Atlas lay essential groundwork for the future planning and design of hotspot cities and regions as interdependent ecological and economic systems.”

Some background on the project is found in both Précis which provides a roadmap to the site, as well as an essay “Atlas for the End?” which alludes to the first modern atlas of Ortelius, the Theatrum Orbis Terrarum (Epitome of the Theater of the World) and the dawn of a new, albeit already populated, world, ready for exploration and exploitation. As mentioned: “In 1570, when Ortelius published his atlas, the European imagination could literally run wild with whatever might be ‘out there’. Now, a mere 450 years later, that vast, mysterious world of diverse peoples and species is completely colonized and irreversibly altered by the material and conceptual forces of modernity. Whereas Ortelius marked out modernity’s territorial beginnings, this atlas—by focusing on the remaining habitat in the world’s 36 biodiversity hotspots —rakes over its remains.”

The extensive essay lays a formidable foundation for the research, touching on the impacts of the past 450 years and the loss of biodiversity through urbanization, and the identification of hotspots, as well as how cities play a huge role. As quoted:

“Although it is not yet well monitored, it is increasingly appreciated that the metabolism of the contemporary city, no matter how divorced it might feel, is interconnected with the sources and sinks of the broader landscape. It follows then that environmental stewardship is as much a matter of urban design as it is landscape ecology. As Herbert Giradet insists, it is in cities “that human destiny will be played out and where the future of the biosphere will be determined. There will be no sustainable world without sustainable cities”.^7“

The themes touch on the foundations of the shift towards the Anthropocene, and our changing ideas about nature, stewardship, and it’s relationship to the profession of landscape architecture, touching on McHarg’s environmental ethics of the 1960s and also discussing the work of biologist Daniel Janzen and work on restoration of biodiversity using a metaphor of the garden. “Janzen’s ‘garden’ is not an idyllic scene constructed for contemplation, nor does it trade in images of pristine wilderness. Wildland “gardenification” as he refers to it, is just damn hard work. As Janzen explains, it involves “fencing, planting, fertilizing, tilling and weeding … bioremediation, reforestation, afforestation, fire control, proscribed burning, crowd control, biological control, reintroduction, mitigation and much more.”³⁶ Janzen’s garden is a continual work in progress.”

The ideas continue in discussions on the role of protected and connected ecosystems, and metrics, in this case, using the Convention on Biological Diversity (CBD). From the text: “The overarching framework for the project of protecting and reconstructing a biodiverse global landscape is provided by the United Nations Strategic Plan for Biodiversity 2011-2020. The key mechanisms of this plan are brokered and administered through the Convention on Biological Diversity (CBD), one of the three ‘Rio Conventions’ emerging from the UN Conference on Environment and Development (the ‘Earth Summit’) held in Rio de Janeiro in 1992. The primary objective of the CBD is that “[by] 2050, biodiversity is valued, conserved, restored and wisely used, maintaining ecosystem services, sustaining a healthy planet and delivering benefits essential for all people”. To this end, the focus on hotspots provides a locus for where these values intersect globally, as represented with ideas of protection (and lack there of) and the ability to access massive quantities of data collected through remote sensing and being able to map it using available technologies (while cautioning against the objectivity of mapping as a practice).

A concluding essay “Atlas for the Beginning” talks about the shift to our new reality of the Anthropocene. A globe view shows “What’s left: the world’s protected areas as of 2015” which illustrates a bleak view of the fragility of the worlds ecosystems. The takeaway is a research agenda that includes more data and analysis, as well as developing methods of action, including a “…longer term research agenda is to establish a knowledge sharing network of demonstration design projects across the hotspots which bring landscape architects, environmental planners, conservationists, economists and local communities together to focus on areas of conflict between biodiversity and development. These SEED (systemic, ecological and economic design) projects will show how landscape connectivity can be achieved and how urban growth can be directed in ways that support all forms of life.”

The use of data visualizations, or datascapes, allows for unique comprehensibility of issues, as seen above. “The datascapes show that if the global population were to live (in material terms) as contemporary Americans do, there would be a major discrepancy between levels of consumption and what the earth, according to today’s technologies, can reasonably provide.” One such visual on Carbon Forest (below) shows the theoretical sequestration potential and equivalent size of forest to accommodate current populations, or, in actual numbers, “The 216 billion metric tons of CO₂ emitted by a hypothetical global population of 10 billion such Americans would require 9.9 trillion trees to sequester its emissions.²

“

The series of world maps are both beautiful and informative, spanning a range of topics both physical and social… a wide array of topics.

Each comes with a short blurb and reference. The map on Ecoregions is described as: “The World Wildlife Federation defines an ecoregion as “relatively large units of land or water containing a distinct assemblage of natural communities sharing a large majority of species, dynamics, and environmental conditions”¹. An ecoregion is a biome broken down even further. There are 867 ecoregions comprising the world’s terrestrial and marine ecology. Nearly half of the world’s terrestrial ecoregions (391) are within the hotspots.”

Another interesting subsection is a feature Flora & Fauna, with “the photography of Singaporean artist Zhao Renhui, Director of the Institute for Critical Zoologists, from his 2013 artwork Guide to the Flora and Fauna of the World¹. The guide presents a catalogue of curious creatures and life-forms that have evolved in often unexpected ways to cope with the stresses and pressures of a changed world.” The species are both amazing and somewhat disturbing, such as the bionic AquaAdvantage salmon (below), “…a genetically modified salmon that can grow to its adult size in 16 to 18 months instead of three years. The AquaAdvantage salmon has been modified by an addition of a growth hormone regulating gene from a Pacific Chinook salmon and a promoter gene from an ocean pout.”

16 January 2018

As January is quick turning into London month, we’re wrapped up on the summaries of available books on the subject, including works by Barton, Myers, Bolton, Talling, and Fathers, running a gamut of approaches to walking, studying, and mapping Lost Rivers. I’d also be remiss if I failed to call back a 2016 post on another take on the subject, Iain Sinclair’s 2013 book ‘Swimming to Heaven: London’s Lost Rivers‘ which rounds out my collection on the subject. The amazing amount of hidden hydrology literature provides a solid foundation, however, it is merely the ~~tip of a massive iceberg~~ visible layer of a vast and sprawling underground complex of content, and a starting point for discussing many of the other resources and discussion around the subject, including art, history, exploration, and maps.

A quick search of London and Lost Rivers or something along those lines yields plenty of material, including additional resource from the sources as diverse as London Geezer, which contains an extensive amount of information, to city specific hidden hydrology projects such as the Lost Rivers Project in Camden. A lot of ink (at least digitally) has been spent on this topic, with articles from BT like “8 of London’s lost rivers you probably didn’t know about” to BBC “The lost rivers that lie beneath London?“, the Telegraph (authored by none other than Tom Bolton, “The fascinating history of London’s lost rivers“, and perhaps the most prolific, the Londonist which covers this topic often, with titles like “The Secrets of London’s Lost Rivers” and info on specific rivers like “Counter’s Creek: In Search of London’s Unknown River” (authored by David Fathers) to a multi-part “Lost Rivers from Above: The Tyburn“.

Without going into extravagant detail and barrage you with too many links (there are over 100 I have at this point), it’s safe to say that London is by far the city with the most coverage, and it continues to emerge (such as this interactive virtual reality tour on the Guardian of London Sewers), showing that it’s a topic that continues to intrigue people. For now, we’ll focus on some projects that work directly in the realm of these lost rivers, interpreting them directly through exploration and indirectly through art.

ART/EXPLORATIONS

Much of the interpretive work around hidden hydrology comes from art, in it’s various forms, and much of the art includes exploration, so I’m combining these two ideas in one here. We’ve previously featured artist Cristina Iglesias and her new installation Forgotten Streams in London as more of a site specific example, interpreting the Walbrook in water features outside of the new Bloomberg London HQ.

A spatial approach comes from Sandra Crisp, and her video project from 2010-2012 “Mapping London’s Subterranean Rivers”. This work was “originally made as a site-specific installation for a group exhibition 2010 held in the semi derelict basement under Shoreditch Town Hall, London” A soundtrack was added later and you can check out the full video at the link above.

A short blurb (with my one small edit) from the site: “The film allows the viewer to fly through a 3D map of London, revealing the sites of ancient and subterranean rivers based on research using old maps and books such as ~~Nigel~~ Nicholas Barton’s ‘The Lost rivers of London’. Evoking existing and long disappeared waterways that bubble unseen beneath our feet. Including; The Fleet, Tyburn, Westbourne, Quaggy, Counters Creek, Neckinger and more…..”

A detail shows the intricacy of the layering, in this case highlighting the River Wandle – but the stills don’t do it justice – check out the video for full effect.

Crisp also breaks down the research on the piece, where she shows a hybrid version of Barton’s map that was the basis for the piece, along with some of the ‘making-of’ info that’s pretty interesting.

Amy Sharrocks, a London based artist, sculptor and film-maker, created “London is A River City” from 2009. As she mentions in her bio “For the last four years I have been making work about Londoners and our relationship to water, inviting people to swim across the city with me, floating boats to drift on swimming pools, lake and rivers, tying people together to trace lost rivers and re-create a memory of water.”

The project included walks of lost rivers, which involved using dowsing as a methodology for walks of the Westbourne, Tyburn, Effra, Fleet, Walbrook, and Neckinger rivers. Each of these are beautifully documented (with PDFs as well for download), and worth exploring in more detail. Per her statement “Why I’m Doing it?“, she mentions:

“Tracing these rivers has been a process of layering: new stories over old, our footsteps over others, roads and railways over rivers. Uncovering a past of London I knew nothing about. Connecting to things submerged beneath our streets has uncovered a currency of the city, and enabled a kind of palm reading of London.

The idea of walking is vital to this endeavor, coupled with the dowsing gives it a pyschogeographic slant. From her site: “These rivers lost their claim to space in this city, long ago paved over, with their inconvenient tides and smells, to make way for faster roads and railways. These river walks have championed a human speed, that stumbles, stops to look at things, slows down when it is tired. There is a connection to the speed of water, a meandering dérive to battle the rising pace of modern life. We took the measure of London by our own strides, pacing out the city at our own speed.” Flash-enabled website headaches aside, it’s a good project worth some time to dive in. Read some coverage from the Independent on the Walbrook walk. You can see more about some other work as well at SWIM .

Another project, this time with a poetic bent, comes from via ADRIFT, a project by poet Tom Chivers envisioned as a “…personal interrogation of climate through poetry.”, where he “sets out to explore climate as culture, mapping out the territory of climate science within urban space.” The site has the full list of writings, and a nice archive of some related materials are also on the site. It’s a project of Cape Farewell, which has a great mission of “bringing creatives, scientists and informers together to stimulate a cultural narrative that will engage and inspire a sustainable and vibrant future society”, namely climate change. An image from the ADRIFT site as part of a photoset “Walking the Neckinger: Waterloo to Bermondsey”

A graphic design work Hidden Rivers of London by Geertje Debets takes a different, more visual approach, as “A research on the letterpress technique, while developing the concept and design for the visualisation of the underground rivers of London. London’s terrifying under half… Sometimes you can catch a glimpse of this underground life, but when you look better, you find the underground world everywhere, especially the underground rivers. The names of the underground rivers are used in street names, places, houses, companies, schools and orchestras. The locations of these places show you how the river floats.”

The work of Stephen Walter got a bunch of press a few years back, with this map of London that “…traces the lesser known streams, sewers, springs and culverts of the capital in intense, hand-drawn detail.” Some enlargements of these maps, via the Guardian:

Another of Walter’s work that is worth seeing is the 2012 “London Subterranea“, which “…aims to shine a light on this clandestine infrastructure and it presents perhaps the first comprehensive map, open to the public, which places so many of its features alongside each other. It geographically tracks the routes of London’s Lost Rivers, its main sewers, the tube network and it’s ‘ghost’ stations including the Crossrail project. It also pinpoints archeological finds, ruins, known plague pits, secret governmental tunnels, the Mail Rail and the Water Ring Main tunnels. Epithets to the ‘underworld’ of crime, and the scenes of notable killings such as the acid-bath murders get a look in. So too does the site of the infamous Tyburn Tree and its many buried corpses that still lie in its wake undiscovered.”

On the topic of the subterranean, photography as well plays a part, with many of the London area rivers featured in a National Geographic photo-essay, “11 Rivers Forced Underground“. A book on the subject I’d like to pick up, Subterranean London: Cracking the Capitol (2014), is described via a blurb from Amazon: “Bradley L. Garrett has worked with explorers of subterranean London to collect an astonishing array of images documenting forbidden infiltrations into the secret bowels of the city. This book takes readers through progressively deeper levels of historical London architecture below the streets. Beautifully designed to allow for detailed viewing and featuring bespoke map illustrations by artist Stephen Walter, this unique book takes readers to locations few dare to go, and even fewer succeed in accessing.”

The publication had some acclaim, with one of the images winning an architectural photography award, along with some controversy as noted in the CityLab article “The Photography Book London Officials Never Wanted You to See” which outlines some of the sticky issues of urban exploration, access, liability, and such. Content addresses more than just hidden waters, but does include some amazing photographs as seen below.

This resource on London sewers from 2011 that looks to no longer be actively maintained, is ‘Sub-Urban: Main Drainage of the Metropolis‘ which looks at the drainage via sewer exploration and photography: “Alongside more traditional study and research practices, such as access to archival materials and the use of other historic and literary resources, we apportion equal importance to the hands on scrutiny of our subject matter. Taking time to explore, investigate and photograph London’s sewers affords us a greater understanding of the often complex architecture and gives practical insight and knowledge that cannot be gained from any amount of time spent thumbing through books and documents.” There’s a number of links on the site to other endeavors, as well as some great imagery, both current of their explorations, and some historical work, along with the timeless phrasing of the section “Close Encounters of the Turd Kind“.

And when you’re done exploring, you can always grab a pint at Lost Rivers Brewing Company and drink the range of available beers inspired by the rivers themselves, and perhaps peruse Ben Aaronovitch’s 2011 book “Rivers of London“, where he created a story around various water deities and river spirits on the Thames and areas of London.

HISTORY

The concept of hidden hydrology is intertwined with history, so threads weave through all of these art installations and explorations. The history of the development of London is fascinating and overwhelming, but there are some great resources like British History Online, which has resources on the topic like the six volume “Old and New London” written in the late 19th century, to sites like Connected Histories, which provide timeline based search tools, or links from the London Historians’ Blog.

On the topic of Lost Rivers, the history of the Big Stink is pretty key historical moment, which was a vital impetus behind what became the modern sewage system and led to the demise of many urban rivers. The idea of this also led to “a piece of Victorian science fiction considered to be the first modern tale of urban apocalypse”, William Delisle Hay’s 1880 novel “The Doom of the Great City”, which is covered in depth via this article in the Public Domain Review.

You can also access primary sources, such as following along with Sir Richard Phillips as he explored the edges of London in 1817, in “A Morning’s Walk from London to Kew“.

Some visual history comes via ArchPaper “What a difference 400 years makes: Modern and medieval London contrasted in hand-drawn cityscapes” which takes historic drawing viewpoints and redraws them showing the current urban configuration.

A fascinating thread that came from some of the books was the legacy of Spas, Springs, and Wells that have been a long part of the history of London. There are some good sites to engage with this history, such as London’s Holy Wells, or the resource Holy and Healing Wells, highlighting around around the globe, including London. There’s some great documentation such as the book mentioned by Barton, Foord’s “Springs, streams and spas of London: history and associations” from 1910, and one mentioned to me by David Fathers, Sunderland’s “Old London’s spas, baths, and wells” from 1915, both great resources for hidden hydrology. An illustration from Foord, showing a 1733 engraving of one of these places, Tunbridge Wells:

The history of the Thames River Postman is a bit more random but worth a read, outlining H.L. Evans who delivered mail along the Thames. “The Thames Postmen played an important role connecting people who lived on the river with the rest of the world. They also became something of a local celebrity being a constant in the fast changing landscape of the river. Considering that the job was not without its dangers, it was remarkable that the Evans dynasty managed to continue for over a century.”

A visual resource COLLAGE, is an image database of over 250,000 images from The London Metropolitan Archives and the Guildhall Art Gallery, and also includes a picture map so you can locate them spatially in London. A quick perusal found me in the Serpentine in Hyde Park, which showed this 1795 “View of Cheesecake House, Hyde Park.”

The concept of the larger regional picture is the website Vision of Britain over time, which is full of great information, and specific to the landscape is the book ‘Hidden Histories: A Spotter’s Guide to the British Landscape‘ by Mary-Ann Ochota which helps decipher the immensity of history through interpreting landforms and other traces. From a review in Geographical:

“There is so much history to the British landscape. What with its stone circles, hill forts, mines and umpteenth century cottages, the land is marked with centuries of use. This can make it hard to read, like a blackboard written on hundreds of times and never erased”

As you can see, plenty of great work has happened and is still happening in London. This is not an attempt to be comprehensive, and there’s tons more out there on specific rivers and locations, so consider this a teaser of sorts and google away for more. I’m trying to find a simple way to share the mass of my resources and links online for further reading and reference, so stay tuned there, and future posts will likely expand on this rich history around hidden hydrology. As a last reference to London, the last post in the series for now, following the lead of New York City, will be on maps.

NYC: The Welikia Project

Jason Kingarchaeology, case study, city, creeks, cultural, ecology, geology, history, infrastructure, maps, new york, places, precedents, rivers, streams1 Comment

As I mentioned, New York City and the larger metropolitan region is an important case study in hidden hydrology, with a range of interesting activities spanning urban ecology, history, open space, art, subterranean exploration, and much more. As a city with a long and vibrant history it’s not surprising that the story of water would be equally compelling. The following few posts will expand on some of the key activities that shape the hidden hydrology of the city.

Times Square then and now: the area featured a red-maple swamp frequented by beavers, wood ducks, and elk. – via the New Yorker

Almost a decade or so ago, I read this story in the New Yorker about Henry Hudson, the year 1609, a map, and an effort by a group of people, including ecologist Eric Sanderson, to research and visualize the historical ecology of New York City. I posted this and posted it to my blog Landscape+Urbanism. This was one of the catalysts, and I’ve discussed this project in the past as one the key Origin Stories around my personal interest in Hidden Hydrology.

The publication of the ideas with the publication of the Mannahatta book (originally out in 2009 and with new printing in 2013) and this broader work by Eric Sanderson (and his very well loved TED Talk) and crew on visualizing and creating rich data landscapes for Manhattan and the larger region is constantly compelling, and the shift to a broader scope under the name The Welikia Project in 2010 was really exciting to see.

The Welikia Project expands the provides a rich and well documented study of the historical and ecological study of New York City dating back over 400 years and inclusive of a range of interpretation from art, ecology, and design. The overview of Welikia here provides a much longer and more complete synopsis of the project, but I’ll pick some of the interesting ideas I think are worth of discussion in information larger ideas about hidden hydrology.

The main page offers a range of options that the project provides. Per the overview page, “The Welikia Project (2010 – 2013) goes beyond Mannahatta to encompass the entire city, discover its original ecology and compare it what we have today… The Welikia Project embraces the Bronx, Queens, Brooklyn, Staten Island and the waters in-between, while still serving up all we have learned about Mannahatta. Welikia provides the basis for all the people of New York to appreciate, conserve and re-invigorate the natural heritage of their city not matter which borough they live in.”

Tools include some downloads include curriculum for teachers to use, and some publications and data also available which would be fun to explore more. A few notable bits of info worth exploration is this page “How to Build a Forgotten Landscape from the Ground Up”, which is a nice overview of the methodology used by the Welikia team, and provides a nice blueprint for organization of data that is transferable to any locale.

The original historical 1782 British Headquarters map was the genesis of any number of overlays that, once digitized into GIS, provided a historic base to layer additional information from other sources, along with inferences by professional ecologists and other members of the team. These were also able to be georeferenced, which allows for the overlay of historic to modern geography, which becomes the basis for some of the larger interactive mapping we’ll see a bit later. A map series from the Welikia site demonstrates the layering and aggregation possible.

Elevation differences from 1609 to today

The concept of Muir Webs was also a fascinating part of the original Mannahatta book, so you can learn more about this on the page and via this presentation “On Muir Webs and Mannahatta: Ecological Networks in the Service of New York City’s Historical Ecology”

Welikia Map Explorer – Lots of interesting background that I’ve literally barely scratched the surface of. As I mentioned, the beauty of Mannahatta was the visualization of the historic surface, and through mapping with georeferenced location, provided an easy opportunity to create overlay maps of historic and modern. The key part of this project is the Welikia Map Explorer, which offers a simple interface that can unlock tons of information. Starting out, you have a full panned out view of the 1609 map visualization for Manhattan.

By selecting an address or zooming, you can isolate locations or just navigate. It’s got that same video game quality I mentioned in my recent post about the DC Water Atlas, with some exploratory zooming and flying around the landscape looking at the creeks, wetlands and other area, you half expect to click and launch some next part of a non-linear exploration game. The detail is amazing, and the juxtaposition between the very urban metropolis of New York City with this lush, pre-development landscape is striking both in plan, as well as some of the 3D renderings above.

You can then select any block and it will pop up a box that allows you to access lots of data underneath on a smaller level.

The interface provides layers of site specific data, and breaks down items like Wildlife, potential presence of Lenape (original native inhabitants, and Landscape Metrics. “Welcome to a wild place: this block in 1609! Through the tabs below, discover the wildlife, Native American use, and landscape factors of this block’s original ecology, as reconstructed by the Mannahatta Project. You can also explore the block today and sponsor the Mannahatta Project into the future.”

The Modern Day tab relates back to OASIS maps of the modern condition, making the connection of specific places easy to discern. “Landscapes never disappear, they just change. Click on the image below to see this block today through the New York City Open Accessible Space Information System (OASIS) and learn about open space and other contemporary environmental resources.”

For the beautiful simplicity of the map, it’s easy to lose sight of the fact that this is dense with real data and models that attempt to provide a real viewpoint to what each parcel was like 400+ years in the past. We discuss baseline conditions much in design, stormwater, ecology and habitat studies, and this level of evidence-based, site scale data is so important to decisonmaking not just in terms of former waterways, but in restoration and management of spaces. This is summed up on the site:

“An important part of the Mannahatta Project is not leaving ecology in the past, but to appreciate it in our current times, to see how we can live in ways that are compatible with wildlife and wild places and that will sustain people and planet Earth for the next 400 years.”

Visonmaker.NYC – Of the more recent expansions of this is the creation of Visionmaker NYC, which “allows the public to develop and share climate-resilient and sustainable designs for Manhattan based on rapid model estimates of the water cycle, carbon cycle, biodiversity and population. Users can vary the ecosystems, lifestyles, and climate of the city in an effort to find and publish sustainable and resilient visions of the city of the future.”

Worthy of a full post on it’s own, the idea is to emphasize the link between the Mannahatta era of 1609, the current era four centuries later, around 2009, and a future world into the future another 400 years in 2049. This gives a great opportunity to create a key linkages between historical work, current scenarios, and future conditions.

As they mention: “A vision is a representation of a part of New York City as you envison it. You select an area and can change the ecosystems – buildings, streets, and natural environments – as well as the climate and the lifestyle choices that people living in that area make.” and you can also view other published visions done by users of all ages. The interface is similar to Welikia, as it allows an overlay of layers with varying transparency for comparison.

More on this as I dive in a bit, but you can also watch a more recent 2013 TEDxLongIslandCity video shows this tool in more detail:

The mapmaking is of course pretty awesome, and they keep posting new visualizations and updates, such as this 1609 topo map, posted via Twitter via @welikiaproject on the “Preurban (year 1609) topography and elevation of #NYC”

There was also some great local quirky info, such as this map and historic photo showing perhaps the strangest remnant geological remnant in a city I’ve seen. Via Twitter from December 2016, “29 Dec 2016 “Rocky outcrops in NYC, were mostly concentrated in Manhattan and the Bronx and composed of schist and gneiss.”

You can and should also follow Sanderson via @ewsanderson , continuing his work at the Wildlife Conservation Society and to see him giving talks and tours around the City. A recent one mentioned that “After seven years of effort, he will share for the first time the digital elevation model of the pre-development topography his team has built, discuss why the climate and geology of the city together make our landscape conducive to streams and springs, give a borough by borough tour of ancient watersheds, and suggest how we can bring living water back to the stony city again.”

Sounds great, and I wish sometimes to be a bit closer to be able to experience this around these parts. Continuing to inspire beyond Mannahatta to the broader Welikia Project, Sanderson and all the crew that make it a reality is a great example anywhere in the world of what’s possible in tracing the threads between history and contemporary environmental issues. If someone today gave me a chunk of money and said do this for Portland or Seattle or both (and honestly folks, we really should) I’d jump on it in a second.

Meanders

Jason Kingcreeks, cultural, ecology, explorations, history, places, precedents4 Comments

A brief aside to contemplate the concept of hidden hydrology, both as a subject of study and as an agent for change. While I’ve been inspired by the concept for some time, I’ve only recently tried to formalize this, collecting information and starting this blog in September 2016. Call it my doctorate in Urban Studies that I never finished, happening over the web, with little to no outside supervision, mostly in my free time from 10pm to the early hours of the morning.

I get mixed reactions when I mention the project, spanning a sort of incredulous ‘Why?’ to an excited “Wow!” with all variations in between. This concept is indicative of the root of my own journey and sometimes my struggle, being simultaneously inspired while trying to figure out what to do with information. On one hand, is just endlessly fascinating (others would agree), and my information gathering, generalist nature wants to find every detail there is to find. And while having an extensive collection of notes, images, maps and resources on my computer is satisfying in a way, it does lack a certain sense of purpose. On the other hand there’s sort of a perceptual disconnect with why any of this matters amidst the plethora of contemporary issues, and my productive landscape architect, designer, urbanist, cartogaphic, activist & ecological nature wants to connect this historical ecology to the greater issues of regenerative strategies of place.

Thus the tagline I originally came up with is a shorthand for both a duality that hints at both potentials, and I think still inspiring:

“Exploring lost rivers, buried creeks & disappeared streams. Connecting historic ecology + the modern metropolis.“

Sometimes it just takes a while to figure out what an end game can look like, and you have to dive in and see where it takes you. I’m calling this, in the spirit of hydrological study, the Meanders, as I’ve titled this post, and it’s been fun to see it played out in presentations, dialogue, and writing with not really a set purpose or goal. I’ve had in my mind, beyond the blog, a book or series of books, perhaps which could be historical, design or urbanism or something spanning all. Also I have toyed with the idea of online atlas, an exploratory video game, a series of historical images superimposed on modern scenes, art installations, tours, and much more. I’m still working on the specifics of where it may lead, but realize it’s not one destination, but many.

At a foundational level the study will focus on Seattle and Portland, as a locus of study and between the two, a venue for comparative analysis and places I live and know well (and have easy regular access to). While both are Pacific Northwest cities that were founded around the same time (1850s), their evolution and histories diverged much due to geography, topography, and hydrology, with Portland built around rivers and Seattle shaped as a city tied to the oceans and lakes. Beyond this obvious dichotomy, there are a number of differences which will be part of, and perhaps fundamental to, the study. One of which is notably politics, which tends to shape place as much or more than those ‘natural’ forces, played. Maps of the two show the unique differences, and the ‘blank’ slate to be filled with oh, so much potential.

PORTLAND

SEATTLE

Thus the core will expand around these cities, and include a continual focus on Explorations, walking, recording, and connected with the experiences of what is gone and what still exists. The goal is to walk/map/explore every hidden stream in each city, and use this along with mapping and history to provide a documentation of hidden hydrology. While the focus will be on these two cities, there is so much information to bring from the wider base of knowledge that allows the analysis to be well informed. Seeing the immense depth and breadth of information that exists and all the forms it can take (which hopefully you’ve seen in these posts), there are ample bends and side channels for us to navigate – but the focus on these two places allows for focus energy for generation specific to place. This hopefully alleviates the danger of just continually searching and compiling information without acting.

In that vein, as precedents, in the past year, I’ve posted summaries of many cities focusing on hidden hydrology, including posts that study the inner workings of cities like Indianapolis, Los Angeles, Washington DC, Philadelphia, San Francisco Bay Area, Rome, Vancouver, Toronto, as well as both Portland and Seattle. to varying degrees. These are the the dozen or so “core cities”, which, along with New York City and London you’ll see in a bit, which have the most fully expansive studies ongoing for hidden hydrology. Each have activities and viewpoints that are specific to place, but all are tied together with connections between water, then and now.

I’ve also touched on other areas around the globe, including Boston, Lexington, Munich, Montreal, Mexico City and Venice, and will continue to offer smaller snapshots of other communities, as there are literally hundreds of fascinating stories to tell. These studies show a wide range of activities these projects take on, including art, tours, literature, advocacy, history, ecology and more, as well as the broad geographic reach of the concept of exploration, in its many forms, of hidden hydrology.

There will be many more posts to come come from all of this, but I wanted to add the two cities that have by far the most expansive and inspiring hidden hydrology efforts I’ve discovered to date: New York City and London.

New York City is one of the inspirations I’ve mentioned, with the Mannahatta project a lofty goal of mine to apply to my own home places, and the work done by others to document the hidden hydrology of the New York region is phenomenal. I’m looking forward to sharing more of this.

And London, perhaps more than any other city, has been so well documented in terms of hidden hydrology, with countless books, maps, ruminations, explorations and more, each with a unique viewpoint and much rich history to draw from. Over the course of the next few weeks, I’m going to take multiple posts to sum this up with New York, as there’s a lot to cover.

Additionally, beyond continuing to document places as precedents, there are a bunch of fascinating topics which enrich these spatial stories, and also inform my own activities. I’m constantly inspired by artists using hidden hydrology as a medium, so will continue to include more examples, both site specific, and including techniques around soundscapes.

Light Meander – River based sculpture in Nashville by Laura Haddad & Tom Drugan

The literary connections of historical waterways is worthy of discussion also, as another of the key inspirations come from both David James Duncan and Anne Whiston Spirn. The connections to language and place names that span cultures, and a thorough acknowledgment of colonization and appropriation is an important aspect of any historical endeavor. Mapping as a subject is vital to this study, including historical ecology and methodologies for mapping that uses new technologies to connect old and new and display these connections in inspiring ways.

The ecological and the hydrological are at the root of rivers, creeks, streams and watershed, providing a context for understanding the past and the present in terms of something this is ever changing, blending soils, geology, climate, ecology and understanding of aquatic systems to infer the historic and investigate opportunities for historical baselines as a metric for regeneration. This requires understanding the potential to restore, but also moving beyond ideas of daylighting as the only option we have, with a more nuanced and historically informed continuum which integrates, culture & art, ecology & habitat using design and science– restoring the key functions of urban streams in a form that evokes, mimics, and celebrates, but doesn’t rely on pure restoration for the original creeks.

Stories of place and process, maps and images, people and words, all aggregate, some sifting through and precipitating in eddies, others taken downstream by the force of the flow. Then again, all this could change. A meander overtopping its banks and connecting with another flow, carving out a new channel, or disconnecting and spinning idly in a lonely oxbow, driving via gravity in tension against rock, all the while creating life at its margins. Not a bad metaphor for a creative process.

The flow may have some direction now, but the nature is still, always, to meander.

Glimpse of Early Seattle

Jason Kingcity, cultural, history, maps, places, precedents, seattle2 Comments

It was great see, via Twitter, local resource @HistoryLink post “100 years ago today, Thomas Phelps’s 1856 map of Seattle was published in the Town Crier”. I saw the post today, so I’m a day late, but the Phelps map is one of those fascinating documents that highlights the historical origins of Seattle and intrigues because it so far removed from want exists today. The article about the map, website, penned by David B. Williams, mentions the map’s original publication on December 15, 1917 as part of the article in the Town Crier (map shown to the left). The article was about “Seattle’s First Taste of Warfare”, found via the Seattle Public Library which outlines an early battle between new settlers and the original residents of Seattle. The full page shows the map in the center (quality of the online version is a bit fuzzy as well – click to enlarge)

The history is summed as such by Williams via HistoryLink.org:

“Phelps’s map depicts what has become known as the Battle of Seattle, when Native Americans battled settlers and the Decatur’s crew on January 26, 1856. The death toll for the skirmish, which ended at 10 p.m., was two settlers and an unknown number of Indians. The map provides what appears to be an accurate depiction of the city on that day, although there is one notable mistake. The settlement’s northern blockhouse, or fort, is in the wrong location; it should be two blocks south, at what is now Cherry Street. (Phelps also shows a southern blockhouse, which was not built until two weeks or so after the battle.) The only other map to depict Seattle around the time of the battle is a U.S. Coast Survey map of “Duwamish Bay, W.T.” Published in 1854, it shows a roughly similar landscape and distribution of buildings.”

A known reprint appeared inr Arthur Denny’s book “Pioneer Days on the Puget Sound”, originally published in a 1888, this map appearing in a reprint from 1908 (but also great is to see the book available as a Third Place Books Rediscovery Edition here). A small version of the map of it from HistoryLink.org (see below for a larger, adapted similar version), with caption from Williams: “1856 map of Seattle by Thomas Phelps of USS Decatur, as published in Arthur Denny’s Pioneer Days on Puget Sound with later street grid superimposed, 1908”

Many historical maps just exist as a singular object to depict a place in a point in time. Phelps’ map seems to exist along a continuum from it’s original sketch of which there is no record, to various prints, updates, hybrids, and transformations over the span of decades, all of which are adaptations of events that had happened some half-century or more in the past. As Williams mentioned separately in a blog post, on his GeologyWriter site about the map: “Many, many editions of the map have been produced.”

The other version that has a fixed date, and mostly commonly used as I’ve seen it, is that redrawn version by Clarence Bagley from 1930, recreating the “1856 map of Seattle by Thomas Phelps of USS Decatur, enlarged and revised.” The 1930 version shows the “Officers of the Sloop of War Decatur”, and a more extensive street grid, and is signed by Bagley. (This image is from Pinterest here as finding a good digital original with source is tough) There’s also a sepia version around cropped with tape marks and a big seattlepi.com watermark, but the same map.

As Williams outlines the unknowns and uncertain history of the map deftly in his article, he mentions “We do not know why Bagley produced this map, who he produced it for, or how he distributed it. Nor is an original of it known to exist. Copies are found in the holdings of Seattle Public Library and University of Washington Special Collections. Nor is it known how Bagley acquired a copy of the Phelps map. Perhaps he could have acquired it from whoever supplied the map to Alice Harriman, who published it in her 1908 reprint of Arthur Denny’s Pioneer Days. Bagley had originally published Pioneer Days, in 1888, but that edition did not include the Phelps map. Harriman did consult with Bagley so he may have had access to an original, though it is unclear why Bagley would wait until 1930 to produce his edition of the map.”

The provenance of others is a question, below is one of those alternative versions that just includes some format changes but unknown date, and stripped of the additional information added in 1930. This larger version via DorpatSherrardLomont that also points out one flaw in the original, as included the annotation: “Phelps map of Seattle. He by now famously misplaced the blockhouse one block too far north of its real location on a knoll at the waterfront foot of Cherry Street.”

The map shown below is titled ‘Map of the Attack on Seattle’, which alludes the the original story. In this case it is from Access Genelology site for the Washington Indian Wars, 1855-1856. It looks like a version of the original that uses the same graphic style, in a sepia tone that cleans up the original map with updated fonts, and the titleblock shifting to the upper right (not sure about date of this one)

An alternate version that David Williams has on his blog, and as he mentions, “This is one of the more unusual. It is owned by the University of Washington Special Collections. I have no idea where it was printed or who the engravers were.” adding, that there were “…several unusual aspects. 1. Addition of “hostile” to Hills & Woods thronged with 2. Addition of “skidroad” to Lake Trail & Skidroad 3. Labels Thomas Phelps as a Lieutenant instead of Commander” ( date unknown)

This expanded version from DorpatSherrodLomond locates the original map within the larger grid of streets and pioneer claims, using the original graphic style as published in Denny’s book.

I’m sure it’s not uncommon, but it’s one of the interesting aspects of the map, as summarized, that it is not just a snapshot of an event in a place, but that it has yielded lots questions about copyright in later years between those wishing to use the map for publication. Williams concludes: “For such a famous map, there are many unanswered questions: When exactly did Phelps draw the original? Does an original exist?”

And for me, when looking at a map that provides a foundation for a place, the questions are both fascinating and make one questions the fidelity of memory, production, reproduction and tracings. Whole explicit or accidental it shows the agendas (and talents or lack thereof) of the mapmakers. The story of the Phelps map is a crucial one for Seattle history and hidden hydrology, and it does offer some context for early shoreline and land fill to office later. While we’d like highly accurate and globally positioned map or story, often reality is that we get a different, more subjective and fluid tale. And as it is a touchstone to what ends up being a crazy development of the City of Seattle, perhaps a little mystery isn’t such a bad thing.

Original text quotes from “Thomas Phelps’s 1856 map of Seattle is published in the Town Crier on December 15, 1917″ via HistoryLink.org, by David B. Williams, originally published 3/24/2015. Maps are credited to other sources because they are so incredibly small on the HistoryLink.org site to even be legible (one of my few pet peeves with an otherwise amazing resource).

David’s site Geology Writer also has more history, and tons of great info on Seattle History, by Paul Dorpat, Jean Sherrard, and Bérangère Lomont on the DorpatSherrardLomont site.

The Water in the Wood

Jason Kingarchaeology, history, infrastructure, precedents26 Comments

The inventiveness of early builders constantly provides us with wonder at their ability to create systems from available materials. The use of wood logs as piping for water and sewer is one of those logically illogical things that makes a lot of sense, but also boggles the mind when you consider the immensity of urban infrastructural systems that relied on this as the primary water and sewer conveyance technology for many years. A May 2017 article in The Washington Post, “Discovered: Philadelphia’s high-tech, totally natural plumbing of 1812″ shows the use of tree trunks, in this case, a series “…of 10-foot pine logs, laboriously drilled to create a 4- to 6-inch center opening and bound together by iron couplings… The pine pipes lay buried and forgotten for two centuries until a worker sank a backhoe in the 900 block of Spruce Street earlier this week.”

Part of the original 45 miles of wooden mains in Philadelphia, expert on all things water in Philadelphia, Adam Levine via his great site PhillyH20 (see also my post here for more) provided some, including some additional history and imagery of the wooden pipes, in this case “A section of wooden water pipe, long out of service, removed from a Philadelphia street in 1901. It had been installed about 1801.”

Other cities obviously used similar technologies, via a fascinating site by Jon C. Schladweiler, The History of Sanitary Sewers we can find some good history and lots of imagery of wood pipes, including bored elm & hemlock used in London as well as Philadelphia and other US Cities where it was employed. From the site:

“The use of bored elm pipes underground with quills of lead running off into the houses of the well-to-do seems to have begun in London as early as the 13th century. All the old London water companies that appeared between the 16th and 18th century used bored elm pipes for distributing water. “

The natural taper of trees allowed for fittings that mirror the flange of modern pipes, and the holes were bored out manually, aided some times by the use of fire to burn out heartwood. A couple of images from The History of Sanitary Sewers , showing “Bored hemlock (wood log) water pipe, laid about 1754. Early wood log pipe was used often for either water or sewage conveyance.”

The concept of ‘fire plug’ was also explained, where wood pipes could be tapped when there was a fire, auguring through the wood to get at the water (or installed at intervals) and once marked, could be replaced by driving a redwood plug into the hole – thus, the fire plug. An image of this, an example from Philadelphia from a wood pipe with metal banding that was removed in the early 1900s.

An pair of articles from the NYC Environmental Protection mentions the discovery in 2013 of a section of 19th Century Wooden water main during repairs, and some of the history of this in New York infrastructure back as far as the 1820s.

The image above shows the excavation and pipe, with some context via their site.

“The wooden mains were installed in the early 1800’s and were discovered in 2006 during routine utility upgrades that included the replacement of water mains in Lower Manhattan. Adding to the uniqueness of the discovery, when unearthed, the two wooden pipes were still connected, to form a 26-foot section of the city’s original 19^th century water distribution system. While several New York City institutions, including the New-York Historical Society, have pieces of wooden water mains in their collections, there are no known examples of complete sections still intact. Once on display, the wooden mains will help educate New Yorkers and visitors about how clean drinking water helped New York grow into a modern metropolis.”

Another image shows wood water supply pipes, in this case excavation of some pipes installed in Bristol, England, dating back 500 years.

Historical precedents for the use of wood as pipe date back even longer, up to a few millennia, probably to when people began to convey water in earnest by ‘mechanical’ means. Via Dr Susan Oosthuizen (who posts great stuff on Twitter) there was an interesting link about Dutch dam builders (from New Scientist, 1996), which along with the fact they were ‘plagued by lice’, mentions preserved wooden logs used as pipes that were found, using dendrochronology, to have been from around 100-70 BC. “The dig has also uncovered dams and sluices built along an estuary. The dams were shut to keep out high tides, and the sluices were opened at low tide to allow water to drain from farmland that would otherwise have been tidal marsh. One dam, says de Ridder, is in the same place as a modern bridge with a similar tidal barrier and sluice. “They were regulating the water level on a large scale,” he says.”

A sketch showing what these tidal sluices using logs may have looked like comes from a sketch Dr. Oosthuizen posted via Twitter along with the quote “Late IronAge banks kept seawater off Dutch coastal marshes at high tide; & were set w/ wooden pipes to drain dams of fresh water at low tide”

Later iterations use wood in somewhat different ways, typically using ‘staves’ that were milled in lengths and banded with metal straps to create a tight fit, and didn’t require boring. The use of wood that had natural waterproof characteristics, such as cedar and redwood, aided in water tightness. As the saying goes, ‘Wood Pipe is Good Pipe’.

The wood stave offered the option of being able to reach dimensions much larger for greater conveyance (the above shows a range from “3 to 120 inches in diameter”, and allowed for greater expansion in the use of projects, shown here as a diagram of outfall sewers from Niagara Falls which includes both brick tunnel sections and a super steep wood stave flume.

This one below is via sewerhistory.org shows a wood stave sewer line here in Seattle, from around the 1930s, which was a common type of installation of the era. You also see the images of Tanner Creek from this previous post show installation of a similar wood stave and brick in Portland in the 1920s, the preferred method of erasure of urban creeks. along with brick sewers that were becoming more common. Will do a bit more digging on where this is but looks like the image below shows an outfall to Lake Union?

Forgotten Streams – Cristina Iglesias

Jason Kingart, city, creeks, london, precedents, rivers, streams1 Comment

Quick post to show the installation by artist Cristina Iglesias, ‘Forgotten Streams’ which is located at Bloomberg’s new European Headquarters in London. The revelatory landscape is woven through three different plaza spaces, evoking the Lost Rivers of London, namely the Walbrook.

Via ArtNet News:

London’s “lost” river Walbrook, which the Victorians built over, appears to have been uncovered this week. The Spanish artist Cristina Iglesias’s Forgotten Streams (2017) now flows gently through the heart of the capital’s financial district, appearing in three places in the pavement outside financial media giant Bloomberg’s new £1 billion ($1.3 billion) headquarters. It is her first public work in London.

While obviously a metaphorical interpretation, the proximity to the actual route (not exact but close) to the Walbrook activates the historical ecology of place. And I was surprised, actually shocked as I was looking at the original images trying figure out the material used, that it is cast in bronze, developing layers of matted shoreline along with differing water flows and pools. As abstracted ecology, the integration of this type of artwork into a high-visibility project is great, and while providing minimal ecological value, the historical value is a positive.

I think they are pretty beautiful, but it was funny to read the review from the Guardian on the Norman Foster designed building, and a specific reference to this work: “In a civic-minded gesture, there are three new public spaces at the corners of the site, adorned with water features by Spanish artist Cristina Iglesias, although her green-patinated bronze layers of matted foliage resemble fetid swamps – perhaps a sly comment on the financial services industry.”

The theme is not a new one for Iglesias, who has tackled similar water-centric themes in previous work (amidst one of the most confounding web interfaces I’ve encountered in some time) and uses the cast bronze as a medium for waterways in other projects in her native Spain, as well as Belgium. More to come on her work as I dive in a bit, but a cool project to encounter. An image of Iglesias, working with a similar material in the swamp, if you will via CNN:

Thanks much to David Fathers for the tip on this one via Twitter.
