Olmsted Scholar Feature: Exploring Relationships Between People and Water

By Sarah Bolivar, 2015 University Olmsted Scholar

Now that I am in my third and final year of the Harvard Graduate School of Design (GSD) Master of Landscape Architecture program, I think back to the query that brought me to the design field: how people manage water, a transboundary resource. In retrospect, this interest has remained constant, although I could not have imagined the various scales and issues I’d study pertaining to water. Through the GSD, I have been fortunate to examine stormwater in Nepal, the role of paths in the context of tsunami evacuation, and now, a thesis around tribal salmon harvest in the Pacific Northwest.

During the summer of 2014, with the support of the South Asia Institute and GSD Community Service Fellowship, I traveled 15 hours by plane and 16 hours by bus to Surkhet, Nepal, a verdant valley overlaid by housing, commerce, and agriculture in the subtropical Terai belt. A friend at Kopila Valley, a school serving 350 students, connected me with the managing non-profit, BlinkNow, which invited me to provide landscape design strategies for a new school complex. I led hands-on workshops so students could learn about landscape architecture and I could learn about their favorite spaces, but I struggled to find the best ways to integrate students’ voices into the project. One clear element was the monsoon season that would soon come, and with it, potential flooding or erosion throughout the school. Part of the design strategy revolved around tackling and revealing these water flows. A week after I returned to the states, a monsoon caused rivers to swell, and massive flooding coupled with landslides left hundreds without homes.

Given that Nepal is prone to earthquakes and landslides, I was eager to learn more about places that could serve as precedents for responding to natural disasters. With the financial support of the Asia Center and GSD Penny White Fund, my friend, Jessie Booth (MLA ‘16), and I traveled to low-density coastal cities in Japan, Kamaishi and Ishinomaki, both devastated by the 3/11 Tsunami. We sought to understand the role that landscape could play in supporting natural disaster preparedness. Specifically, we wondered how pedestrian evacuation paths could become imprinted in the collective memory to serve residents during emergency and non-emergency times.

One of the biggest takeaways was each city’s reconstruction plan did not necessarily work in tandem with neighboring cities’ plans. Each city could be broadly characterized either by a “bottom-up” or “top-down” reconstruction approach. Additionally, most affected cities are continuing to invest in structures that have a singular use and narrow lifespan, such as tetrapods and seawalls. This spring, Jessie and I will synthesize our research findings into a document we can share with our friends and partners in Japan.

Working in Japan and Nepal allowed me to be acutely aware of the challenges designers face when the site has a different cultural context than one’s own, the site is thousands of miles away, the work is pro-bono, and the work is conceived within an academic umbrella. Each of these conditions renders its own opportunities and challenges.

I reflect constantly on the politicized nature of my role as I develop a thesis around a place that is dear to me, the Salish Coast, located in the Pacific Northwest. In this region, I’ll be exploring the role that design can play in supporting salmon habitat and harvest to thereby protect indigenous sovereignty rights for the Lummi and Nooksack Nations. Given that indigenous people have been systematically oppressed through physical force and political contracts, I must understand that my language and actions are too, as my friend Elizabeth Bragg of the Blackfoot Nation would put it, “colored by colonizing practices of the past.”

And as I begin to develop the project, I come back to the issue of water, in this case, the hydrological conditions that affect salmon reproduction. With the guidance of my thesis advisor, Jane Hutton, and thesis cohort, I look forward to continuing to explore the relationship between people and water in all its multifaceted forms.

Sarah Bolivar is currently working on her thesis, as well as planning International Women’s Day on March 08 with the GSD Women in Design team.

Olmsted Scholar Feature: Spaces of Conflict, Spaces of Opportunity

By Logan Littlefield, 2015 University Olmsted Scholar

The effects of conflict on the urban landscape are far reaching and multi-faceted.

Beirut, Lebanon is a case in which the continued political instability spawned by its 15-year civil war (1975-1990) has exacerbated a physical and cultural erosion of the public realm. This has allowed areas of natural, cultural, and civic heritage to be co-opted by private luxury development, preventing them from serving as potential devices to foster social cohesion and civic identity. The unprecedented tabula rasa reconstruction of Beirut’s central district by a private development company exemplifies this condition.

My graduate thesis project, Confronting the Present: Towards a Civic Realm on Beirut’s Urban Fringe, explores the opportunities presented by peri-urban infrastructural landscapes to address this condition. To do so, my research was two-fold: an inventory of designated and spontaneous public space types in Beirut, and a rational for civic space in more unlikely spaces.

beirut01Inventory of public space types

The peri-urban Beirut River became a testing ground for a new prototype of civic space. Opportunity lies in its ambiguous ownership, neglect, infrastructural qualities, and tenuous identity as a natural feature, where an intervention is less likely to spawn gentrification. It was also consistent with inventory findings that the dominating adjacency for more informal forms of public manifestation was infrastructure.

Though the space is aesthetically unlikely, socially and demographically speaking however, it is fitting for social cohesion since, though situated in the largely Christian eastern half of Beirut, the site is located within the most prominent Armenian neighbourhoods. This community resisted taking sides during the war, making their areas relatively neutral grounds for interaction compared to other more cloistered Christian or Muslim districts. There is also increasing ethnic and religious diversity here due to affordable rents, urban migration and the influx of refugees.

The proposed design prototype deploys and hybridizes local spatial types onto the infrastructural landscape to create a new urban topography, the next iteration in the evolving transformation of the Beirut river from seasonally flooding estuary to channelized riverbed.

A series of platforms are created, some programmed and others not, which together form a transverse connection of civic space across the river and multiple highways to meet the needs of surrounding neighbourhoods.

Some of the approaches or tactics used in my thesis work were generic, and others are very specific. This is something that I am grappling with as I relate these research interests to my new locale: South Africa. Public realm erosion is an issue here as well, as is a history of conflict and and social instability, albeit for different reasons. However, the fragmentation or lack of use of the public realm by all often has to do with fears of violent crime due to wealth inequality, which is a much different social context than in Beirut.

My thesis project was the recipient of a 2015 ASLA Student award and can be viewed in more detail at:

Olmsted Scholar Feature: Sustainable Sediment Management in the Los Angeles Basin

By Nathaniel Oakley, 2015 National Olmsted Scholar Finalist

“A week ago the rains began in Los Angeles, slicking the streets into road accidents, crumbling the mud from the hillsides and toppling houses into canyons, washing the world into the gutters and storm drains…When the rains come in Los Angeles they always take people by surprise.”

                                                                        — Neil Gaiman, American Gods

Towering above the Los Angeles basin at the kink in the San Andreas Fault lies the transverse San Gabriel Mountain range. Rising over 10,000 feet into the sky at its highest point, it is known for its destructive debris flows as written about extensively by John McPhee and others. The tectonic force of the Pacific Plate grinding against the North American plate uplift the mountain range at the rate of one millimeter per year (fast in geologic time), and the repeated cycle of denuding conflagrations and orographic precipitation erase much of that progress.

Toward the western end of the range, the headwaters of the Arroyo Seco River (a major tributary of the Los Angeles River) make their way into a watershed that is over 95% urbanized. At the moment, this highly developed watershed is protected from flooding and the ever-eroding San Gabriels by a series of anthropogenic infrastructural interventions, the largest being the Devil’s Gate Dam and a series of concrete channels that the Arroyo now flows through.

arroyoseco-watershedThe Arroyo Seco River Watershed flow path and context

The Dam, plagued by a history of sedimentation, is now at half of its original capacity. Normally, excess sediment is excavated and brought to nearby landfills, but recent fires and rain events have left L.A. County playing catch-up in order to maintain reservoir capacity. If storage behind Devil’s Gate is compromised, communities along the Arroyo are potentially at risk of flooding. Surprisingly, many of these nearby inhabitants were unaware there ever could be a flood risk as most of the time the channel remains dry, save for urban runoff trickling through the low-flow portion of the channel.

In addition to the sediment build up, downstream conditions of the Arroyo Seco are bleak. Wildlife habitat has been replaced with cold concrete, and most of it remains inaccessible to the public as the invert can drop off precariously to depths of 30 feet in some reaches and can quickly turn dangerous during storms. During heavy rains motorists have found themselves stranded, clamoring to the channel walls, requiring swift water rescue. Very little water that stems from the Arroyo Seco is allowed to recharge groundwater supplies, and the habitat-building sediment it delivers from the San Gabriels is trapped, destined for nearby landfills.

A strengthening El Niño climate cycle is predicted heading into 2016, which will hopefully give drought-stricken California much needed precipitation. With the return of wet weather, fast moving storm water will return to the Arroyo Seco delivering sediment from the crumbling slopes of the San Gabriel Mountains. Devil’s Gate Dam will be tested, while potential aquifer-replenishing rainwater will be sent directly to the ocean via impervious channels. Herein lies opportunity for discussion and implementation of unique water conservation and sustainable sediment management design strategies that go beyond the business as usual, Sisyphean, approaches of fighting sediment and flushing rain water out of the city.

My Senior Project at UC Davis, The Barrier: Seeking Sustainable Sediment Management Solutions for Devil’s Gate Dam, discusses these issues and proposes regenerative design strategies and interventions to balance natural sediment delivery, water storage, flood control and habitat restoration.The report and a short video discussing this research can be accessed at:
