STUDIO OVERVIEW
THE TEAM
The master's research studio was an interdisciplinary exploration of resiliency in the Boston region, through many lenses. The teaching team was structured as a partnership between landscape architects, a planner, and an architect to support this endeavor, with workshops from visiting experts across design disciplines. The students themselves came from diverse backgrounds ranging from architecture, interiors, landscape architecture, ecology, and others, infusing the research and design work with a layered approach.

STUDIO OVERVIEW
THE CHALLENGE
In the wake of Hurricane Sandy and other recent weather events, the vulnerability of the eastern seaboard to sea level rise (SLR) resulting from climate change has become manifest. By 2050, 100-year storms are expected to occur every 2 to 4 years in Boston, and the economic impact of major storm occurrence is predicted to cost approximately $460 billion. Planners and designers have the opportunity to shape the way our cities prepare for and respond to the pressures of SLR. This studio explores sustainable urbanism in the Boston region by investigating the impacts of SLR on the public realm and open space systems, built form, transportation networks, and economic forces in the region. Recent disasters such as Hurricane Sandy, Hurricane Lee, and Hurricane Irene have raised awareness of the need to plan for resiliency; this research offers a chance to think proactively rather than reactively, to consider mitigation and adaptation as well as protection, and to integrate social, physical, economic, and political situations. Building on group research and analysis exercises, students generated individual design-research projects around the themes of proactive and resilient built environments. Research and design proposals consider not only coastal areas, but also inland neighborhood centers vulnerable to SLR.

STUDIO OVERVIEW
THE BOSTON PLANNING CONTEXT
Hurricane Sandy awakened coastal cities to the reality of their vulnerability to climate change and extreme weather events. Boston was fortunate that Sandy hit at low tide - if the storm had landed 5 hours later, Boston could have seen similar devastation to what occurred in the New York / New Jersey metropolitan area. The City has taken Sandy as a call to action. The Boston Harbor Association has emerged as a thought leader in the region, organizing research to provide policy makers, planners, designers, and property owners with tools to assess vulnerability and increase resilience to coastal flooding over time. Their work includes the 2013 Preparing for the Rising Tide report, the 2014 Designing with Water report, and are organizing the Boston Living with Water international design competition in early 2015. Advocating for a long-term resiliency strategy for the Greater Boston area, Sasaki also launched a research initiative on sea level rise called Sea Change. The Sea Change team tapped into the firm's interdisciplinary practice to engage in preparedness planning at the building, city, and regional scale. Sasaki designers also collaborated with experts in engineering, academia, advocacy, and policy making to harness sea level rise expertise and push design thinking further.
THE BOSTON HARBOR ASSOCIATION'S PREPARING FOR THE RISING TIDE REPORT
Sasaki curated an exhibition to showcase this research, highlighting Boston's vulnerabilities and potential design strategies. The exhibition shared the Sea Change research with the broader community in an engaging and accessible format, rich with graphics and interactive media. Events associated with the exhibition catalyzed a conversation among designers, city officials, real estate leaders, and academics. This studio builds on this rich context to investigate and propose multi-disciplinary design strategies to address the challenges posed by climate change in the Boston region. 5
SYSTEMS
A systems approach is fundamentally different from traditional analysis. Traditional analysis entails separating individual elements of study; in fact, the word analysis comes from the root meaning “to break into constituent parts.� Systems thinking, in contrast, focuses on how something is related to and interacts with the other components of a system. Rather than isolating smaller and smaller parts of a system for study, systems thinking requires continuous expanding of a view to take into account other relationships and interactions. The studio conducted an analysis of features such as topography, hydrology, ecology, landscape character, built form, ownership and land use, community, and demographics, framing an approach with an appropriate scale for resiliency and regional thinking.

Because of Boston's coastal nature, the city's multilayered infrastructure systems are vulnerable to sea level rise. The studio examined the workings and connectivity of vehicular, pedestrian, and transit systems, as well as water-control infrastructure and its vulnerability to SLR and storm surge. Much of Boston's transportation infrastructure, including Logan International Airport, MBTA hubs South Station and North Station along with 48 other T stations, the Conley shipping terminal, rail networks, surface roads, and entries to tunnels such as the Sumner, Callahan, and Ted Williams, would be innundated in both the 2050 + storm surge and the 2100 projections for SLR.

Other critical city systems, including eight power plants, one wastewater treatment plant, six fuel terminals, and numerous hospitals, schools police stations, fire stations, and government buildings, are also in the path of future flooding. The studio explored how to build redundancy into infrastructure networks, such that if one point fails, other pieces of the networks withstand.

Boston's ecosystems are a rich mix of coastal marshlands, riparian corridors, and upland forest habitat. However, with time, much of Boston and its ecoregion has become urbanized, highly paved, and impervious, disconnecting and eroding these natural resources. The studio examined environment and the unique ecology of Boston at various spatiotemporal scales, identifying seen and unseen processes that greatly affect the region’s ability to withstand rising waters.

Downtown Boston is a densely built, highly paved urban environment containing the majority of the City's high-rise structures. While much of this neighborhood is built on the higher ground of the historic land mass, some areas, such as Faneuil Hall and South Station, will be under water in the 2100 SLR scenario.
Back Bay is a mixed-use neighborhood composed mainly of 5-story brownstone structures in a gridded city fabric. This neighborhood is built on historically filled marshland and is vulnerable to flooding in the 2100 SLR projections.

SEAPORT DISTRICT
East Boston is a largely residential neighborhood, characterized by two- to three-story attached multifamily housing, interspersed with large tracts of industrial land and Logan International Airport. Its landform is characterized by drumlins, with some of the oldest city fabric on these hilltops. The low-lying areas between drumlins as well as other areas of filled marshland are vulnerable to flooding in the 2100 SLR scenario.
The Seaport District is the northern portion of South Boston, composed of a mix of large-scale industrial and commercial properties and vast surface parking lots. This is one of the fastest developing neighborhoods in the City. Despite all of the new investment happening here, almost all of the Seaport District is projected to be underwater in the 2100 SLR scenario.

A study of several economic and social factors in the region exhibited dichotomies between the City of Boston and the surrounding suburbs. The City has a much younger median age than the Metropolitan Area Planning Council (MAPC) region, due to a large student base and population of young workers. Land value is also rising around Boston and decreasing in the suburbs. These factors all have implications for future investment in public infrastructure, private development opportunities, and sea level rise vulnerability.

Boston has the fourth-highest income disparity of any city in the nation. There was a clear emphasis on industrial, commercial, and institutional land use within Boston, all of which exhibited a multi-hub structure with a focus through the downtown Boston/ South Boston area. This major focal point is at risk for impending sea level rise and storm surge inundation. While Boston is one of the most educated cities in the country, spatial economic disparity is visible and closely associated with ethnic minority-dominant tracts and unemployment.

From the detailed systems analyses that defined vulnerabilities in Boston’s infrastructural, environmental, social, and built realms, the studio developed strategies with the goal of increasing the resiliency of the Boston area to sea level rise by addressing system-wide vulnerabilities. Clearly stated selection criteria and analytic mapping helped select areas of focus. Each project employed prototypical design responses that addressed resiliency or adaptation for the system and could be deployed at various locations throughout the region. These consisted of architectural interventions, public realm and open space proposals, physical planning related policy investigations, or other district level strategies. Resultant projects make a clear link to analysis and research, but are morphed and nuanced by context and ground conditions.

WATER WEB JORDAN BRADLEY Typical city drainage infrastructure moves water as quickly and efficiently off the land as possible, contributing to flash flooding and transporting contaminants like road salts and oils directly to adjacent water bodies. The water web is a non-linear redundant system that connects streets, parks, garages, and basins designed to slow, treat, and infiltrate stormwater into the existing linear infrastructure. A portion of South Boston was identified as a testing ground for the water web concept, because of its location at the Reserved Channel on the South Boston Waterfront where a quintessential historical neighborhood - Southie - meets the rapidly developing Innovation District. This site is vulnerable to both the 2050 + storm surge and the 2100 projections for SLR.

Seaport Common is a 130-acre green development located along the Reserved Channel on the South Boston Waterfront that will protect important surrounding industrial properties and residential neighborhoods. The current site is fully impervious and the linear stormwater management that currently exists sends the contaminated water directly into the Reserved Channel. Seaport Common’s largely permeable surface and its water web stormwater management
system work to capture, store, filter, and reuse water on site. With its high, sloping levee, Seaport Common protects against storm surge and sea level rise, and contains rock breakwaters and saltwater marshlands to slow and soak the surge. There is a vast improvement of pedestrian circulation on the site with minimal disruption of the current existing building square footages or land uses. The site solutions serve as both protection and activation of the area.

The water parks, garages, and streets use a tank system that filters then stores the storm water for reuse. When the water streets are filled, underground pipes transfer the overflow to the larger capacity water garage or water park. When the park or garage is filled, the pipes then transfer the overflow
to the water basins located on the edge of the reserved channel or to the storm water pipes that exist. This allows for a relief in pressure on the existing infrastructure and generates water that can be reused for irrigation, toilets, and cooling the generation station’s mechanical equipment.

DOWNTOWN ALLEY MEITAL TSAFRIR GANOR Much of Boston’s low-lying financial district and Chinatown neighborhoods are in the path of projected sea level rise. These areas are densely built environments that suffer from a lack of open space to serve their residents and an overabundance of stormwater resultant from their highly paved environments. The many alleys in these districts offer an opportunity to layer functions, treating and infiltrating stormwater through blue roofs, green walls, and porous paving, and doubling as social spaces for the neighborhoods. The project examined three prototypical types of alleys in the district based on their physical dimensions and vehicular and pedestrian access patterns. The proposal for each alley type is related to its specific environmental conditions, such as solar exposure, and its spatial capacity to accommodate various social programs.

To combat issues that similar industrial cities face, prototype strategies of HOLD, TRANSFER, DISTRIBUTE, and FLEX are utilized to address issues of flooding, access, mobility, and zoning. Resultant prototypes include a topographical cell structure capable of adjusting to inundation levels, a shared-use pathway that challenges notions of accessibility and occupation, flexible platforms constructed of recycled materials, and a prioritization model for industrial relocation. These prototypical studies are paired with a sitespecific strategy that creates a framework for a resilient open space system for the City.

MYSTIC MARSHES LUIS BARSOTTI
The Mystic River was historically a tidal corridor, rich with habitat and brackish marshes that filtered water and armored adjacent communities against flooding and storm surge. Over time, as the Mystic's edges have urbanized and the River has been dammed and channelized, marshlands have atrophied or been filled for valuable waterfront property, leaving adjacent communities vulnerable. 62
This project proposes marsh (re)construction on some of the industrial, vacant, and underdeveloped land at the edge of the Mystic, providing more resilient natural landscapes to help armor against SLR and storm surge. Industrial lands with high risk of contamination by flooding were identified and strategically relocated to make space for these marsh systems. Community programming and access to the Mystic riverfront were also important considerations of the proposal.

Boston's MBTA rail network is currently a radial system, with all lines converging at several key locations downtown, such as South Station, North Station, and Park Street Station. This configuration makes the system vulnerable, as many of these downtown stations are in the path of projected sea level rise.

The bridge connects the two cities, while mitigating a large amount of stormwater and providing the public a multi-use urban park. The Charles River North Shore expansion proposal utilizes a wetland edge that allows rainwater to drain and filter naturally before being returned to the River. The wetland also acts as a sponge and levee in the event of a sudden rise in the River's water level.

DESIGN AND THE RESILIENT CITY SUEN 7130 MASTER'S RESEARCH STUDIO 1 FALL 2014 This studio explored sustainable urbanism in the Boston region by investigating the potential impacts of sea level rise on open space systems, built form, transportation networks, and regional economic forces. Building on group research and analysis exercises, students generated individual design-research projects around the themes of proactive and resilient built environments. Research and design proposals consider not only coastal areas, but also inland neighborhood centers vulnerable to rising waters.
