Regular readers of the blog know of my long-time passions of both Vegitecture and Hidden Hydrology, which both dovetail nicely into the larger themes of Landscape+Urbanism. While the L+U blog has been relatively intermittent, I’ve been hard at work developing a new website and blog for the Hidden Hydrology project. The goal is to culminate the work in some form of publication, but regardless, it seemed time to focus on that element in it’s own. I’m also giving a talk at the Washington ASLA conference in Spokane later this month (April 21), so excited to share more to a broader audience. Simply put, the project is summarized as:
“Exploring lost rivers, buried creeks & disappeared streams. Connecting historic ecology + the modern metropolis.”
Without going into too much detail that may be gained by going to the site itself, the project is broken down into four sections. The first section gives a quick overview of hidden hydrology and links to some of my original inspirations, including Anne Whiston Spirn and David James Duncan, along with an early, evocative map of Portland, along with the amazing historical ecology around the book Mannahatta.
A bit longer summary gives some context for the endeavor: “At the basic level, hidden hydrology is the buried, piped and disappeared waterways that flow under our urban areas. Development has driven underground these surface streams that used to weave through our cities – and with them we’ve lost the connection to natural systems, and robust ecological habitat that urban waterways can provide. Beyond just focusing on pure daylighting and restoration, the exploration, mapping, and study of hidden hydrology offers new ways to conceptualize a range of interventions that reconnect us to our history and offer glimpses of solutions for the future. It’s a broader concept of ‘restoration’ that looks through lenses of art, landscape architecture, urban ecology, and planning to define ways to celebrate, connect and regenerate our places.”
The second section are links to many of the resources available, including precedents, projects, and resources from around the globe. While linking to the other pages, I’m also providing links to some of the posts, including a diverse mix from Rome to London, San Francisco to Lexington, Kentucky. The range of projects isn’t limited to projects, but encompasses art, mapping, poetry, literature, dance, stream daylighting, films, community engagement, and history.
A couple of highlights, including the project “Ghost Arroyos” in San Francisco:
Or the cool mapping work of David Ramos in DC at Imaginary Terrain.
The third is an ongoing exploration of themes in a more expanded format, the site is built aroud a blog that has delved into some of the resources, and projects, but also allows for some rumination and coverage of original project work. Of the 25 or so posts to date, many have covered cities and projects, expanding to case studies and deeper investigations. These include projects inspired by hidden hydrology (such as Town Branch Commons in Lexington, top below), as well as historical maps and photos referenced in a literary context (Iain Sinclair’s ‘Swimming to Heaven’), and more in depth historical ecological studies (San Francisco Estuary Institute) to show a few.
The diversity is what surprised me, to different tendrils which weave beyond just mapping but into a multitude of subjects. An early post on the site, is illustrative of this concept, and is still one of my favorites, focused on the novel by Ben H. Winters, Underground Airlines and it’s use of the hidden hydrology of Indianapolis to tell a futuristic narrative of modern day slavery.
An excerpt from the novel explains this in a bit more detail.
“I cleared the trailer park and passed a jumble of picnic benches and playground equipment and stepped carefully down the slope of the ravine and swung the heavy beam of my flashlight along the creek. Now it was clear, with the water swollen by the rains, the direction the brown water was still flowing. The black mouth in the base of the shallow hill was an entrance, not an exit. This low little trickle of mud water was a kind of rivulet, a poor cousin of a creek, and this spot behind the motor court is where some long-ago engineer had diverted it.
The creek was called Pogue’s Run. I’d found it on the map. I’d looked up the story. This small waterway was discovered at the turn of the century – the eighteenth turning into the nineteenth — discovered and named and recorded, penciled in on early maps, when the city was not yet a city — when it was a gathering of huts, a stopping place on the way to other places. The small river was inconvenient for the city fathers and the grid they’d drawn. So they did just as Mama Walker said: they ran it underground.”
Beyond the fringes of hidden hydrology include some diversion into the very cool Atlas of Oblique Maps, a fascinating set of historical climate maps from the 1850s, and the ever popular Fisk maps of the evolution of changes to the Mississippi River.
The fourth, which is more of a long-term is projects, is still in nascent stage, but offers the potential to showcase original work around Hidden Hydrology, specifically in Portland and Seattle, but encompassing some other miscellany as well. Currently it highlights some early presentations, as well as base-mapping of the Cadastral Survey for each city, the springboard for further analysis.
The Mississippi maps inspired me to use some of the documentations to animate the changing course of the river within the valley over the last 4000 years. These more
There’s a ton of great information out there, yet it’s an area of study that seems relatively untapped and full of potential. If you’d like to contribute, know of some great case studies, and have the bug for historical maps, and how these can inform ecological design today, give a shout. In the interim, check out the site and follow @hiddenhydrology on Twitter.
And stay tuned for some more explorations here at L+U related to urban ecology and habitat, and more posts on some recent vegitecture, as I am working on some related projects and doing some more focused research in these realms.
