After bit of a break I’m hoping to write more frequently on all things Hidden Hydrology. For some context, in this time away I have been researching more deeply Portland’s Hidden Hydrology, delving into archives for stories of my local disappeared streams, buried creeks, and filled wetlands around the metropolitan area. I’ve also compiled a composite map of Portland spanning the 1850s through the 1900s to piece together the most complete version of the hidden hydrological layers that existed pre-settlement. I’ve kept up doing research more informally in the broader and mostly sharing on Twitter and Instagram, which are both simpler media for messaging, but also seem lacking in depth that more expansive writing can capture. While it may be true that blogging is no longer a viable medium, I feel a need to write more deeply, and more often, and more personally about my home, my history, and my places. This will hopefully lead to writing more broadly as well in journals, and culminate in my ultimate goal — to write a book (or more than one) on hidden hydrology.

A few recent thoughts, ideas that I take with me into the next journey.

WATER STORIES, HUMAN STORIES

The origins of my interest are documented on the site here, including a strange and wonderful Portland map by Metro, the inspiring academic work of one of my landscape architecture idols, fiction and place-based non-fiction from a local legend, and Mannahatta’s deep eco-hydrological historic mapping. These inspirations and the subsequent research into the overall concept of hidden hydrology documented here on this site has left numerous imprints on how I think about hidden hydrology as a concept and a methodology for integrating into planning and design. Upon reflection, I have typically always approached the project through the lenses of hydrology, history, ecology and place, with the human element occupying a supporting side-narrative to these other elements.

Every story has a uniquely human interface and the phenomena of hidden hydrology is no different, with a variety of actors involved in the discovery, use, manipulation, destruction, protection, and restoration that are all story arcs of urban streams, wetlands and other water bodies. I have always seen the people involved in more broad strokes, as populations and groups acting against nature and natural processes, or conversely communities and coalitions being often negatively acted upon and attempting to preserve and protect systems. Rarely did I connect people to places in a meaningful way beyond faceless groups, only rarely placing individuals and their stories and essential ingredients to unlocking the true history of place.

As origin stories, the native Chinookan people have occupied and shaped the waters of Portland for centuries. There are specific narratives of leaders, like Concomly as part of the larger Chinook territory in the late 1700s and early 1800s and Kiesno (aka Cassino) who was located near Portland on Wapato Island, who was also an important figure through the early to mid 1800s , The native stories and start to take shape via early explorers, whereby they drift into settler narratives told about those indigenous people and never told by them. Thus we remember ‘discovery’ and the snapshots of what written narratives and maps were documented, but know less about the life and the interaction with many of the places in the region beyond a few major areas of significance that were spiritual centers and places of food gathering and trade. I challenged myself to weave these stories into the narratives, and although I feel more informed, I’ve barely scratched the surface, so the next steps are to engage and learn from descendants and hear stories of places that were of significance to Chinook people in the past, and those that are still resonant today.

In Seattle, I walked and wrote about Licton Springs, which explored the deep indigenous connections to place in a remnant urban stream – weaving together the long and contentious history, which was recently given protection as a landmark of cultural significance to Coast Salish people. Many of these stories need to be told, and the opportunity to connect our diverse history to water places – the water stories and human stories, continues to intrigue me.

Broadening the cultural lens, I’ve written about Tanner Creek and the Chinese farmers who cultivated lands adjacent to the creek using the amazing resource by Marie Rose-Wong on early Chinese residents of Portland, documenting the erasure of the creek and the Chinese farms in tandem, both slowly disappearing from Portland in the wake of ‘progress’ that wanted neither the Chinese people, nor the messiness of flooding, steep gulches that stood in the way of a modern metropolis.

The narratives feature places like Guild’s Lake, a contested area with a variety of actors working to destroy, displace and erase historic waterways to pave the way for development and industrialization, with little thought to the impacts ecologically and socially to these actions. As you map out the timeline of erasure for many waterways, it’s never one person or one big move, but a variety of consistent, incremental actions, driven by the need for progress and growth, that privileged the needs of few over the impacts to many. The missing piece of this is again the human dimension, the root of all of these stories were the people who occupied these places, and how they, and their actions, gave life to the unique water places in the community. And as other forces removed the waterways, how they were impacted by the places are lost. The places are not coming back, but but hopefully through the stories some idea of that experience can re-emerge and remain.

Another significant narrative in Portland’s water history is the intersection with the African American story, told through the emergence and eventual destruction of Vanport City. There are many narratives as to the cause of the flooding and destruction of in the1940s worth exploring, and the eventual displacement and segregation that happened after the city was destroyed continues to shape the city today.

As my post documenting the amazing OPB documentary “Vanport” shows, these, too are human stories, with interviews and first person accounts of the development and occupation of this novel community, and the lead up to the destruction and displacement of larger populations of people that had lasting impacts and left an indelible mark on the racial history and social structure of Portland.

CLIMATE CONNECTIONS

While Vanport was not a result of climate change per se, this larger narrative of catastrophic flood events also provides a hint at more extreme future scenarios that intersect with my research on hidden hydrology: the connections between the lost and buried streams, wetlands, ponds and water bodies, along with made-land through filling and manipulating shorelines, and how these ultimately give clues to and exacerbate our present impacts related to climate change.

Stories in the mainstream media are reinforcing these connections, and through recent research, and continues to gain prominence and momentum as a dimensions of climate change evolve and the impacts are played out in communities more frequently and in more extreme forms.

There are a number of drivers for the ‘creative destruction’ of water systems in cities. Making land for development by piping creeks, filling gulches, ponds, wetlands and shorelines to make developable land offers the chance to grow and continue to build. Much of this was also an element of the modern safety movement that was concerned with life and property damage from flooding creeks, and the related sanitary movement was driven by public health concerns, often by removing access to polluted waterways. In short term and in earlier times, these efforts may have seemed good approaches but come with some unfortunate baggage in loss of ecosystem function, and lack of resilience.

Flooding is obviously not a new thing, and is not always the result of removal of waterways not of climate change. However it is not difficult to make general connections that flooding often follows the historical shape of water in cities, and that removal, filling, and piping of creeks, streams, wetlands and ponds has lasting impacts to the hydrology and that the impacts will be more evident as climate change raises sea levels, increases extreme precipitation and storms, and increases urban heat.

A recent NY Times editorial by Eric Sanderson makes this case, unpacking impacts of recent extreme weather and hurricanes and tracing that to lost streams that wove through New York City. The simple statement of “Water will go where water has always gone.” sums up the phenomenon, while giving us an interesting new (old?) methodology for predicting impacts by using historical hydrological systems in new ways. Beyond that in the past year, my Twitter feed is filled with stories of flooding in Europe, UK, and around the US, a global climate change induced impact all traced back to the link between historical waterways and current, human-caused climate change. Lots more on this topic to come.

EVOLUTION

As I researched more from the archives of local newspapers and uncovered more unique, human stories, the narratives became less about places and the lost waterways, but how these created a tableau of life. Rarely were stories these idyllic and utopian, but painted a picture of daily life and the struggle to build a city carved out of the forest at the confluence of two rivers. Often they were narratives of greed, racism, and exploitation, focusing on power and money which were allowed to run rampant in a time of very little environmental policy and awareness of impacts.

The water stories become stories of native people who developed thriving communities that were in a short span of time decimated by disease, violence and displacement from their lands and waters. The stories of Chinese farmers who lived on the margins of gulches and ponds in Portland, who contributed to the building of the community and were rewarded with racism and erasure from their places of productivity and community. The devastation of a flooded African American community of Vanport left ship workers and their families, engaged in supporting the war effort while building a life in Portland left many without a place live and led to a continuing and marginalization that continues today.

These historical water stories connect people to place and add a human dimension to an ecological history. When woven together with more contemporary climate stories, it also provide a solid foundation for why this work matters in design and planning for the future. It is far from a nostalgic looking back of what’s lost, but rather an opportunity to think about lessons learned related to how we can live and thrive together while growing a diverse community. It is also a blueprint for action on climate resilience, a future-focused approach to planning for urban heat, flooding, and other key resilience measures to make our communities more livable. Call the preliminary phases of this project a good information gathering, understanding what hidden hydrology is. The evolution becomes how to use this information to shape our communities in positive ways. Look forward to exploring and continuing to evolve.
