For planning projects at the city-scale, civic engagement is an essential tool to empower the public to actively participate in envisioning the future of their communities. If done authentically, with an open mind and a willingness to make it comfortable for people to share their stories, the process can be informative and provide a much-needed context regarding the complexities inherent in making urban design choices. The best engagement strategies are people-centric, hands-on, and creative.

A recent resiliency project in Galveston, Texas, offers a peek at how these types of gamified engagement exercises can both inform the design team and thoughtfully engage the public. Galveston is built on a barrier island in the Gulf of Mexico and is a small city with a history of hurricane devastation, most notably in 2008 when hurricane Ike made landfall. A 13-foot storm surge flooded nearly the entire island and in the immediate aftermath, the City’s population dropped from 57,000 to 48,000. 

The project began with an ambitious goal; to develop a community vision plan for Galveston by engaging at minimum 15% of the population. The team, a collaboration between Huitt-Zollars, Asakura Robinson, Mass Economics and Stoss proposed several initiatives that ultimately led to ‘Vision Galveston’, the framework plan that was developed through three rounds of public outreach. Throughout the process, the engagement team focused on involving as many as people as possible, especially the traditionally underrepresented, seeking groups that represented the diversity of Galveston in age, race, sex, and geography.

One of the highlights of the engagement process was an interactive exercise that involved developing a series of 3D printed seawall options that people could shuffle in order to design their ideal promenade, seawall and beach configuration. The seawall, a 10-mile long concrete barrier protecting downtown Galveston from tropical hurricanes, is central to Galveston’s identity and much beloved by the community. In fact, the Seawall is listed in the National Register of Historic Places. According to the report, “Recommendations and concerns regarding the Seawall were raised during the outreach process. This included requests for better access—more parking, free parking, improved connection to public transit, and safe crossings across the busy Seawall Blvd. … There were requests for better amenities for recreational activities along the boulevard and diversifying the land use and businesses across the street from the beach. Since the Seawall is central to the identity of Galvestonians, many people requested further beautification to the Seawall, using landscaping and other means.”

In order to better understand and convey these types of interventions, the Stoss team modeled, then 3D printed various configurations of the promenade, the seawall and the beach which allowed residents to configure their ideal sections. Seawall options included access ramps, a grand staircase, shaded overlooks, skate ramps and natural rocky shorelines.

During community events people were encouraged to play with the sections and share their preferred options which was then recorded by the design team. Not only did the team gather critical insight, but the community had an enjoyable time learning about the options and visualizing possibilities other than what exists there today. These types of exercises help transform a community’s mindset and pave the way for design innovation.

Designers use pleached trees to punctuate a compact public plaza in Toronto. by Petra Geiger

50 scollard bw.jpg

Sometimes, we look to the past to give a modern space a distinct personality. In the case of 50 Scollard, a residential tower in the Yorkville neighborhood of Toronto, our team turned back time and ambitiously resurrected the art of pleaching. Pleaching was a common technique in late medieval to early 18th century gardens whereby trees were interwoven to create dense, hedge-like shapes. Branches were trained over time to weave together and in some cases naturally grafted to become living fences. This process would take years as young branches were trained while they were pliable and nurtured into place as they grew and strengthened. Commonly a frame was constructed with stakes, dead branches, or cords to aid in achieving the desired form. The results are stunning—architectural, sculptural, and formal shapes that serve to frame walkways, gardens and lawns.

In 2017, our team began working on the public plaza and roof terraces at 50 Scollard in conjunction with Foster + Partners. At the ground level, the compact corner plaza space demanded a focal element that could hold its own against the distinct 43-story tower while respecting the historic buildings remaining on site. The solution needed to have an impact but also allow for circulation and a range of programming options such as public events, movie screenings and performances. This is where Stoss designers looked to the past for something new and different. The team presented a bold idea; an undulating canopy of pleached trees that not only oscillates between the building facade and the public sidewalk but also ascends in height. Designed to accentuate seasonal color change, the pleached hedge will be a riot of color in the fall as the trees transition from the green of summer to the bright red of fall.

Translating this big idea into a realistic opportunity has been a challenge and an investment in time and effort. Working with Lanterra Developments, Braun Nursery and PAO Horticultural, Stoss Associate, Marin Braco, has overseen the selection and cultivation process that will ultimately take over 3 years.

 
 

Several tree species were considered  during the design development phase beginning with trees that were used for pleaching historically, including Lindens, Tilia cordata  and European Hornbeams, Carpinus betulus. The team found that many of these species were not appropriate for the conditions of this site—the right tree would need to be able to withstand pressures of a harsh urban plaza, tolerant of drought, salt, wind and disease resistant. With this in mind, the design team narrowed down the selection to 3 varieties of red maples: Armstrong, Red Sunset, and Autumn Blaze. After meeting with the horticulturists and examining both young and mature specimens, it was determined that Autumn Blaze was the best fit for site conditions and design parameters. Characteristics that were considered included:

  • Growth Rate: While a faster growth rate requires more maintenance, it allows for the final form to be recognizable at the time of installation, and fully realized within 5 years after installation.

  • Mature Size: A larger mature tree size allows for more flexibility in the training and trimming process.

  • Branching Structure: Density, pliability, and horizontal growth are all required to achieve the desired results of pleached trees, forming one continuous mass.

Additionally, since the final form requires different canopy heights, the planting was broken up into 5 zones. Zone 1 being the tallest trees, descending down to Zone 5, the shortest. Trees were tagged by zone, with additional trees tagged per zone in the event that replacement is required. 

In all, 30 trees were tagged as primary specimens with an additional 14 selected as replacements if needed. The trees were tagged in October of 2018 and in the spring of 2019 were relocated to the nursery where they will be trained and formed over a 3 year period. While this is a lengthy process, this period dovetails with the building’s construction schedule. If all stays on track, in fall of 2022 the trees will be gently separated, excavated, transported on flat beds and planted on-site—carefully rewoven branch by branch. We can’t wait. This has been a labor of love for our team, stay-tuned to see the results!

World's End: Memory and the landscape. by William Baumgardner

Baumgardner-30bw.jpg

What is the unbuilt? Both historically and contemporaneously, many of the visions and projects of architects come to life only as drawings or sketches. The reasons are many: budgetary concerns, client expectations, engineering difficulties, etc... However, often times the memory of these spaces and places remain as a trace of what could have been. These memories manifest themselves from time to time when construction may have started only to never finish. One such space is World’s End, located in Hingham, Massachusetts, just south of Boston.

World’s End was originally an island before it was dammed by famers and filled to create new agricultural pasture in the late 19th century. After a few decades of farming, the site was commissioned to Frederick Law Olmsted, Sr. to envision and design a high-end residential subdivision with views of Boston through Hingham Bay. Olmsted was no stranger at this point in his career to designing subdivisions with sweeping carriage roads and hedgerows of towering shade trees. However, the subdivision was never fully realized. What is left today is a striking hidden park where one can follow the first lines of Olmsted’s hand on the carriage rows and the aging giant shade trees lining the road. Even further, the land is subject to what could have been, as it was also a finalist for the United Nations Headquarters in 1945, and later on a nuclear power plant.

Each chapter of World’s End’s history can still be seen and felt, even if just for a moment of time. Each day and with each ripple in the water, the site’s land bridge still echoes the tidal shifts illustrating the initial damming by farmers. Large rocks take log of these tidal shifts with stains on their faces. And while the roads and trees of Olmsted still frame the landscape, ecologies old and new are taking back the land. One can see the fragmented woods creeping back together and marshlands taking back the land that was once theirs.

Our landscapes, built and unbuilt, are testaments to visions, shifts in use, and the ever-evolving concept of what could be. Over time, these spaces evolve, perpetually telling new stories in their chapters. In a space like World’s End, we are able to bear witness to a framework come to life without the full build out or vision complete. We as landscape architects can champion these histories and articulate them in new ways for modern and future audiences and help to build a larger narrative of how we as humans, and the land itself, shape the world we live.

Water. Lifeblood to landscape. by Petra Geiger

“Where the waters do agree, it is quite wonderful the relief they give.”
― Jane Austen

No doubt, water is central to the ways landscapes—designed and otherwise—work and thrive. Water has the ability to inspire a playfulness in people, a letting down of the guard, a sheer exuberance in the ways we engage with the environment.

In one way or another, water infiltrates our practice, whether designing a waterfront park subject to climate change and storm surge, or creating an urban plaza that collects stormwater allowing for infiltration and regeneration. More and more, our work involves the challenges of climate change and the re-creation of green infrastructure like marsh habitats that can absorb, filter and accommodate the natural ebb and flow of water—not to mention foster a rich biodiversity. Additionally, the opportunities to re-think our formerly active industrial waterfronts and ports are helping to re-establish the connection of water within the urban landscape.

While we fully acknowledge the important ecological and functional roles water plays in our lives, we also look to transcend the pragmatics of water flows and explore the experiential, the immersive, the sensorial, even the poetic aspects of water. For us, water is both medium and canvas to enhance, to engage in its life-giving powers, to recognize that both the imaginative and physical forces of water are both bigger than and beyond us. Water incites a sense of play and exuberance in people (and animals) that is infectious.

Here’s to recovering the nothingness and mystical powers of water in landscape and the city.

Employing a multi-layered approach to deal with sea-level rise. by Petra Geiger

In Boston, sea level rise is a big deal with even bigger consequences. In fact, a 2018 study suggests, “that some 90,000 homes valued at $63 billion could face chronic flooding by the end of the century — and that’s just in Massachusetts”. With projected sea-level rise of 21 inches by 2050 and increasingly severe storms, Boston has made climate change planning a priority.

In working with the City of Boston on many of their Climate Ready Boston initiatives, such as Coastal Resilience Solutions for East Boston and Charlestown, Moakley Park and Downtown Boston, our team has been knee-deep (literally) in this complex issue. And we’ve learned, there are no easy solutions.

In approaching climate change, we advocate for a multi-layered approach, involving numerous strategies and facets that in combination are effective and actionable, creating spaces that protect, energize, educate, and set up thoroughly new experiences. Applying diverse types of protection methods in combination to achieve success—including green infrastructure, gray infrastructure and, ‘living with water’, our team begins with the foundational belief that infrastructure should do as much as possible, that investments in flood protection should provide multiple benefits including social, environmental and economic.

GREEN INFRASTRUCTURE

Green infrastructure as a tool to combat climate change can no longer be overlooked, it must be scaled up and considered as fundamental to the planning and design process. In this vein, streets, open spaces, even buildings and infrastructures can be designed to act as a resilient landscape, directing, collecting and absorbing water. In some cases, the sustainability measures we design are explicit, as with the lowland marsh that collects stormwater and creates new space for river flooding in Erie Street Plaza; here sustainability is made visible and produces a beautiful space or element that might not be otherwise possible.

Often, though, we try to create special experiences, to bring resilient solutions to life for people. Our quadrangle, Gerstacker Grove, at the University of Michigan, is designed with lush, shady stormwater gardens with interactive lighting features that flicker in response to stormwater entering the garden—amplifying and creating a unique experience.

GREY INFRASTRUCTURE

When we incorporate grey infrastructure, we recognize that, where structural systems are necessary for resilience strategies to be effective, they need to be integrated with aesthetic character and broader landscape improvements, or be tucked away out of sight during non-flooding conditions. Designing “hidden” flood protection structures, including passively or actively deployed flood walls, piers and coastal structures, underground stormwater and sewer infrastructure, and other systems that are part and parcel of the urban environment. In the case of City Deck in Green Bay, WI, storm water protection measures are built into the structure, the seating elements act as flooding barriers as well as discrete collection spots for drainage.

LIVING WITH WATER

Protection against coastal intrusion is not always the first goal of a climate-ready strategy. Being resilient means being able to bounce back, withstanding impacts while being changed by them and adapting accordingly. For example, an approach which allows for flooding in certain areas while consolidating protection in others may be an effective strategy that can help to mitigate the challenges of threading flood protection infrastructure through a dense urban environment. In addition, in key places the landscape can be designed to withstand and even benefit from coastal inundation such as in our L Street Power Plant project.

EDUCATIONAL OPPORTUNITIES 

Lastly, wherever possible we look for ways that resilience strategies can become educational opportunities. How can we bring resilience to life in ways that people feel closer connections to the waterfront, the urban environment, and their neighbors? How can we tune and amplify environmental cycles, through technology and even art, in ways that are meaningful to the daily lives of people and to the life of the city? How can we educate people (especially children) on climate change and resiliency measures? To these ends, we think creatively and inventively about social interactions and resilience. This may include ‘living with water’ strategies that bring people closer to the water as well as other means by which the creation of flood protection becomes part of a community building.

Flat no more. Generating a bench that props us up or lets us slouch. by Chris Reed

Harvard University Plaza custom designed benches.

Harvard University Plaza custom designed benches.

Landscape practice is often centered on ecological and environmental concerns that explore the dynamic, operational, and even physical aspects of ecological systems as a starting point for generating design. But new software technologies have brought exciting generative modeling tools into design practice that allow for a new generation of techniques and fabrication technologies that can play a significant role in shaping design in exciting new ways.

The responsiveness, flexibility, and adaptability inherent in complex systems ecology can be mimicked through generative modeling tools—allowing for dynamic multiplicity and differentiation.

These new modeling techniques, which can be utilized for design inquiry as well as to ultimately generate physical form, allow for an increasing complexity of inputs to the modeling process, producing a multiplication of possibilities that each respond to a slightly different set of priorities or agendas. What does that mean for design? In the case of the benches at Harvard Plaza, it meant the ability to customize seating that is better adapted to different body sizes and body types—or simply offers choice to suit one’s mood.

At the scale of the human body, recent technology allows for the translation of modeling principles and methods into fabrication and construction processes for furnishings and elements, allowing for the generation of non-standardized and non-repetitive units that better serve diverse body types and shapes and differing agendas for how to use public space.

Up until recently, the simple bench had been standardized, in part due to advances in industrial manufacturing processes that found efficiencies in the production of repetitive parts and assemblies. The result was that the act of sitting, hanging out, slouching, etc. had all been simplified and standardized into a typical, mass-produced bench whose formal profile was consistent and was geared toward an average human body. While the body is exceptionally versatile and adaptive—and can make a seat out of a wide range of objects (tree stumps, walls, barrels, logs, etc.)—generative and associative modeling software offer opportunities to customize seating that is better adapted to different body sizes and body types—or preferred ways of seating—while maintaining production efficiencies through evolutions in digital design, fabrication, and production techniques.

In the case of Stoss’ Harvard University Plaza benches, the key was to develop prototypes of different sitting profiles—tuned specifically to different body types and different sitting or lounging positions—and script the software to loft or transition between two different profiles. In this way, a bench could begin with 3-5 different profile positions, as did the benches at the Harvard Plaza, but result in an easily reproducible bench, created from CNC machines at the fabricator’s shop, that accommodate over a dozen different sitting positions or scales.

When this technique was utilized with different starting profiles for 5 unique custom benches, the result is a plethora of choices for how one wishes to sit in public: alone or in groups, cross legged or straight upright, lounging or lying down completely, or with a friend on one’s lap. At Harvard, the overall form is assembled from a series of Alaskan Yellow Cedar “ribs,” mounted to a steel frame; if one rib is damaged during snow removal or the like, the rib number can be retrieved from the digital file and an identical replacement piece fabricated for re-installation. This is still a process that allows for replicability and efficient production, but is better tuned to the body and choice.

Engaging everyone. How design can help build an equitable 21st century community park. by Petra Geiger

For South Boston’s new Moakley Park Vision Plan, civic engagement was crucial.

If parks are the ultimate in public open space, then by nature they absolutely must be equitable, accessible, inclusive and sustainable. Conceptually—and oftentimes in the real world—parks serve as great equalizers, melting pots, places where people of all cultures, races, socio-economic backgrounds can gather, mix, play and learn. Unfortunately though, poor planning, legal statutes, disinvestment, and blatant racism have instilled cultural bias in significant populations. Many people have grown up not going to parks because parents determined they were unsafe, unwelcoming or just plain derelict. On the flip side, people have extreme passions around parks often determined by the sports they play or their cultural practices—like hosting multi-generational family barbecues. Managing the diversity of constituents and opinions is challenging, but nevertheless engaging a broad mix of the community when designing public space is crucial—especially if your goal is to build a park that will delight, engage, inform and inspire everyone—and most importantly make them feel a sense of belonging.

Reimagining the Civic Commons, an initiative focused on, “transforming public spaces to foster engagement, equity, environmental sustainability and economic development in our cities,” is making this a priority in places like Akron, Chicago, Detroit, Memphis and Philadelphia. The organization lists ‘socioeconomic mixing’ as one of their pillar goals stating, “we fundamentally believe shared civic assets should be places where everyone belongs and where different people can share experiences. We believe that by boldly welcoming people of all incomes and backgrounds into public places that encourage human interaction with others, we can rebuild trust within communities — and maybe even rebuild our democracy.”

So, the question becomes, how do you attain civic engagement goals, ensure that a broad constituency is involved, and based upon what you learn, design a park that is inclusive, equitable and sustainable? Toni L. Griffin, Professor in Practice of Urban Planning at the Harvard Graduate School of Design and Founder of The Just City Lab, asks a similar question, “how do people who have been marginalized in urban neighborhoods and cities gain equitable, inclusive access and the opportunity to live productive lives in safe, beautiful, and flexible environments?”

Our recent work in South Boston can serve as a case-in-point. Moakley Park, Boston’s largest waterfront park, is a 90 acre park that is situated between the waterfront and two low income housing projects. For the Boston Parks and Recreation Department (our client), protecting the residential communities inland of Moakley from future flood events and climate change impacts was critical. Yet, the goals for this vision plan were broader. Climate work would in fact be the catalyst to provide an exceptional 21century park for the residents of this community. Retaining and enhancing Moakley as a key active recreational amenity for South Boston through elevated ball fields, a revamped stadium, destination sport courts and play areas with improved stormwater management, along with expanded ecological value, new programming, and places where community members feel safe and comfortable simply ‘doing nothing’ in a shady, green space, were explicit goals. As well as creating equitable access to the harbor, one of Boston’s greatest natural resources.

Moakley Park is a gateway to the Harbor for the communities south of Downtown; South Boston, Roxbury, Dorchester and the South End. In addition, communities further afield have easy access to the park and harbor via nearby subway stops, a 5-10 minute walk from Moakley. Yet, despite its proximity to train stations, Moakley Park is left isolated from its immediate communities through busy roads that span 4-6 lanes of fast traffic. Rotaries at either end exacerbate safety issues and are difficult to navigate. Therefore, an additional goal was to increase the linkages between these communities, park access points, the harbor, and the islands beyond.

Clearly a deep and meaningful community engagement process was critical, something that is deeply embedded in our process at Stoss. Reimagining the Civic Commons sums up our perspective. “We don’t just want to hear people’s opinion about public places, we want them to participate as stewards and advocates in shaping their community’s future. This kind of civic engagement should be central to how communities reinvent and manage civic assets as public places that serve everyone — because that’s the way you build deep and long-lasting support for these places in the first place.”

In designing our public engagement approach, the team considered a broad mix of outreach, both formal and informal, in-person and online. It included open houses and one-on-one interviews (held at or directly adjacent to the neighboring residences), a community advisory group, a bike tour, and on-site activation. Our strategy has always been to take a human-centered approach, engaging individuals, families, stewards and leaders in ways that are enjoyable and fun for them, that let them relax, feel included and empowered to contribute. In-person events had to be accessible and planned at various times/days and publicized through different kinds of media to attract all generations; we were both interested in hearing from those who use the park on a regular basis and from those who, for one reason or another, do not. And, it must be acknowledged that civic engagement is an ongoing and continuous process, garnering detailed and actionable data as the vision plan becomes a reality.

One event of note, a daylong extravaganza named DISCOVER Moakley!, was dedicated to bringing fun and energy to Moakley Park. Numerous public and nonprofit agencies teamed up to demonstrate how simple activation of the park can connect people to the space for a diverse range of activities. The event spanned beyond Moakley’s perimeter and included a beach-themed inflatable installation, live music, acrobatics on the beach, exercise classes in the park, local food and beer, skateboarding, and parkour. Visitors were also asked for input and to participate in activities that exhibited green infrastructure and coastal resilience strategies. This fun event showed participants how the park could evolve into a multi-functional urban waterfront park that combines athletics with resiliency efforts and new program to better suit and connect its diverse community and beyond.

Throughout the planning phase we listened. And learned. The most common improvements requested included flood mitigation to increase field use, improved safety through lighting and road improvements, public bathrooms, and spaces for non-sport exercising. The most common additions included new diversity in play spaces for all ages, new areas for passive recreation like sitting in the shade or community gardening, and winter and nighttime programming.

What we heard significantly influenced the design. A berm and raised landscapes, central to our resiliency strategy, does much more than simply protect the community. They provide significant new social and recreational opportunities as well as physical and visual access to the waterfront. Access to this resource is of great importance for populations with limited resources and for whom the park and waterfront serve as their backyard. While more amenities and diverse programming are key, the design team also carefully considered ways to break up spaces, ensuring that users are encouraged to circulate through the park, to meet, mingle and connect, creating shared experience among people of all incomes and backgrounds. Vehicle free zones, like a pedestrian-friendly promenade to encourage walking and cycling, further enhance connectivity, support social interaction and cohesion, as well as promote cultural diversity.

Zones were established that create environmentally friendly places with increased access to nature and access to all points in the park were carefully considered. The envisioned circulation through Moakley Park is designed to connect with major neighborhood streets to maximize access for the community. Paths extend into the park from major entrances and thread through to allow both easy access to key areas and yet allow people to meander and stumble upon new spaces they might not have otherwise encountered—encouraging the interaction of people using the park.

Moakley Park’s new vision plan takes ardent strides in listening to the community and designing a place where all can feel welcome, included and involved. However, this is just the beginning of the journey. Discovering new economic opportunities for the surrounding community, uncovering ways to sustainably support such a rich and varied park, and ensuring that current residents are not displaced as the community changes are all critical issues to be grappled with, not only by designers but by city planners and the community itself. Legal, policy and regulatory frameworks must be reconsidered and work to guarantee equity, enhance participation and serve to support, maintain and create a diverse and varied community.

NRPA defines inclusion as, “removing barriers, both physical and theoretical, so that all people have an equal opportunity to enjoy the benefits of parks and recreation...reaching the most vulnerable individuals and families—those who suffer from higher rates of health disparities and a diminished quality of life.” We couldn’t agree more.
