INTRODUCTION
Public space is many times a decisive quality people demand when looking to settle in an urban scenario. Today’s cities are focused on leading the way to more innovative design solutions, supporting residents and attracting visitors. The city of Boston is in this process, aiming to provide the public with more opportunities for passive and active recreation. City Hall Plaza has the capability of becoming a popular destination, currently forgotten in the historical context of downtown Boston. Looking past the plaza’s use as an event platform, its remaining purpose is not evident. The plaza has a controversial complexion that undermines its existence as a relevant space within the city, collapsing it further into disrepair. Noted as the worst public plaza in the United States, the importance of its redesign has never been so apparent. Through the determination and dedication of our design team, City Hall Plaza will at last become a valuable and cherished treasure to the city of Boston.
LITERATURE REVIEW
“Where do city people like to be? Not where they feel intimidated by rushing traffic or the blank walls of massive office towers. Not where getting from here to there entails a long walk, wait, or tiresome climb. Not in a blazing or frigid windswept expanse of paving. Not where there is little of interest to see or do. People prefer instead to be in or move through ways and places of comfort, interest, and delight. They enjoy the meandering walk through contracting and expanding spaces. They enjoy the charm of diminutive nooks and passageways - of places where they can rest, to talk or people-watch. Such experiences are seldom happenstance; they must be thoughtfully planned.” John Simonds - Landscape Architecture “Extensive studies indicate that a lack of urban green space can have negative mental health effects that include increased stress, mental fatigue and cognitive impairment – which in turn can have significant physical health implications. Urban green space – especially where neighbors participate in greening activities – can also contribute to building strong, safe communities.” Evergreen “Areas and spaces are minute in scale. Scale, both induced and inductive, is an important design consideration. An object well suited to the open field could be overwhelming in the cityscape. A giant tree, for example, might dwarf an urban complex, while a dwarf tree could give it increased and more desirable visual dimension.” John Simonds - Landscape Architecture

PROBLEM STATEMENT
Although not a typical residual space, Boston City Hall Plaza is a derelict urban space in the heart of the city seen by many as a wasted opportunity. Wasted urban space has become a highly debatable issue and designers are turning their focus to the revitalization of these spaces to reinvigorate the urban environment. There have been many proposals completed by students and professionals to redesign the plaza and building to change the perception of the space from a failing urban plaza to one that promotes sustainability and addresses the social needs of those working and living in the adjacent areas. City Hall Plaza was recently voted as the number one square most dramatically in need of improvement in the U.S. by the Project for Public Spaces. The location of the plaza and the proximity to public transportation offers an opportunity to create a vibrant, socially active, successful public space but the current design negates these opportunities. Landscapes developed along ecological lines will serve to create a powerful aesthetic form. Landscape design reflects humanity’s dependence upon the land ethic and serves as opportunity to reintegrate natural processes within the urban environment. Boston City Hall Plaza exists as a derelict urban landscape void of all natural processes. Replacing “nature� does not fit within the context of the site and the urban environment; however, a program developed along ecological lines will reduce the obscurity of nature in the city and reintroduce sustainable ecological processes in an area that has neglected sustainability in the last half century. Treating the landscape as a process capable of responding to social needs and biological requirements will reintroduce social interaction while connecting people with nature in an urban context. Involvement of users will be critical to the success of our project, as the program will be developed from public input and the social needs of the city.
SCOPE The scope of this project focuses on the function and aesthetics of the plaza. As of now it is a dysfunctional and underutilized space. We plan to incorporate site specific elements to bring a sense of purpose to this space. The redesign will promote a series of integrated program elements to bring a sense of place to this desolate area and also provide beautification to the location. This space is in the center of the city and should be utilized by visitors and residents alike. Providing a pedestrian friendly environment with site specific activities will provide a breath of life into this brick desert. This site is crucial not only to the city of Boston but also as a model to other urban plazas. This is one of the most historic cities in the country; millions of visitors flock to this area every year so it is imperative that the center be an enjoyable place where people can come and congregate for a variety of reasons. Whether people believe the plaza should be torn apart of left alone one thing is clear: the plaza is unsuccessful as a public space. This redesign will prove to be the missing link to the city’s urban green space network. A magnificent plaza should be implemented to capture the historic character of the area that promotes it as one of the most unique and historic cities in the United States.

Mission Statement
The mission of this project is to transform the Boston City Hall Plaza from an underutilized urban landscape into a vibrant, welcoming, and ecologically sensitive space. Creating a culturally inclusive landscape for public gathering, entertainment, and passive recreation will reestablish the plaza as a pedestrian destination. The space will function as a centralized gathering node providing physical, visual, and social connections to the surrounding city fabric. Implementing innovative green infrastructure techniques will reduce the plaza’s environmental impact while heightening the ecological consciousness in the urban area.

Context City Hall Plaza is located on the Atlantic coast in Boston, Massachusetts.
City Hall Plaza is located in the center of downtown Boston yet is disconnected from the surrounding city fabric. The disconnection, both physical and perceived leaves the large civic space subject to redevelopment.
The plaza boundaries are largely defined by the street around it. The site contains local, state, and federal government buildings, defining it as central node within the city.

Christopher Columbus Park
Boston’s dedication to public park land dates back to the early 1600’s when the Boston Common ( the oldest city park in the United States) was constructed in 1634. In an effort to link the Common and other public park land in the city, Frederick Law Olmsted designed the Emerald Necklace in the late 1800’s. Although Olmsted’s plan was never fully realized, much of the Emerald Necklace was constructed and is a popular destination today. In 1991, construction began on the “Big Dig” to replace Interstate-93, a six-lane highway bisecting downtown Boston, with a tunnel system that would reestablish physical connections within the city. A linear urban park system known as the Rose Kennedy Greenway now exists on the roof of the tunnel. The 15-acre greenway traverses through downtown and provides a variety of pedestrian destinations.
Rose Kennedy Greenway
Boston Common
Green space between the historic Boston Common and the modern Rose Kennedy Greenway in sparse and City Hall Plaza stands as a void within the larger park system of Boston. Located in close proximity to both the Boston Common and the Rose Kennedy Greenway, the redevelopment of City Hall Plaza provides an opportunity to connect the existing green space in the downtown area. Creating physical and visual connections to adjacent green space will help reconnect City Hall Plaza with the urban fabric and reestablish the plaza as a destination in downtown Boston.

Ownership & Stakeholders
Federal Government Boston Redevelopment Authority Privately Owned Privately Owned: Public service/utility City of Boston
The complexities associated with the ownership of the plaza and surrounding buildings make any redevelopment challenging. The City of Boston, the Federal Government, Boston Redevelopment Authority, and a mix of private owners all own areas on or near the plaza. Any redevelopment or design changes must engage these stakeholders.

Brutalist Boston City Hall
There is a wide mix of architectural styles throughout downtown Boston. Due to the age of the city, there have been many buildings constructed during different eras leaving behind a wide array of styles. See figure 1.1 The historic buildings surrounding our site are significant because they are major tourist attractions (i.e.. Faneuil Hall and the Old State House). The brutalist style of Boston City Hall is the most prominent feature on site. Many people criticize this style due to its overbearing and rigid qualities. These harsh architectural qualities combined with the empty landscape create an unwelcoming feeling that sends people away from the space. Softening this architectural style will be critical to a successful design.

Figure 1.2 shows the three different MBTA lines and their relationship to the plaza surface. Each line lies at a different depth below the plaza, the green line being the most shallow (avg. 15 feet deep), followed by the orange line (avg. 20 feet deep), and the blue line (avg. 25’ deep).
City Hall Plaza is a complex urban landscape with three MBTA lines (Green Line, Blue Line, and Orange Line) running underneath or adjacent to the plaza. The Green Line occupies the largest area below the plaza, while the Blue and Orange lines skirt by the edges of the plaza. A parking garage used by City Hall and surrounding buildings occupies a large area in the Southeast corner of the plaza. Grates capping vents for the MBTA lines and the parking garage exist on the plaza surface. The extensive subsurface infrastructure limits the amount of area suitable for stormwater collection and infiltration. An abandoned Green Line tunnel runs parallel to the Sears Crescent building and offers opportunities for stormwater storage or re-purposing.

Boston is committed to the improvement of bicycle accessibility through new routes, lanes and bike shares which enable tourists and residents an opportunity to explore downtown Boston and its neighboring towns. It is essential we know and understand this information so we are able to plan for future redevelopments and hubway locations. The future expansion of bicycle infrastructure will have a significant impact on and how users travel to and through the site. In the next five years, City Hall Plaza will see a hubway station located near the Government Center MBTA Station that will increase pedestrian circulation in that area.

Figure 1.3 shows the new development from the Rose Kennedy Greenway. The tallest building is over 500 feet in height and vastly changes the skyline of the area changing shade and wind patterns for its surroundings. Understanding these changes along with circulation increases and differences helps us further recognize problems to decide the best ways to address them.
Figure 1.4 depicts the existing and proposed skyline looking north from City Hall Plaza.
Circulation The redevelopment will directly affect circulation patterns on and around the plaza. Figure 1.3 and 1.4 show the areas of increased circulation. The redevelopment has the potential to generate over 600 new walking trips and dozens of new transit trips. These capacities and dimensions must be considered throughout the redesign of City Hall Plaza

The climate of Boston has a direct impact on City Hall Plaza. Precipitation, snowfall, and wind speed in Boston are higher than the national average making an open expanse of impervious space less than ideal. The current design of the plaza leaves users exposed to these weather events, creating an uncomfortable environment.
Wind Analysis Wind patterns on the plaza are largely influenced by the adjacent structures. The summer winds come from the east bringing the breeze of the Boston Harbor. These breezes travel upward through the site, following the grade change. City Hall acts as a barrier to these winds; forcing them upward or around the massive building. The winter winds come from the northeast. They channel between 123 Center Plaza and the JFK tower and flow into the site. These winds are potentially strong (~20mph) and funnel between City Hall and the adjacent structures. This creates a wind tunnel effect on the south side of the site.

Shade Analysis 0 1 2 3 4 5 6 7 8 9 10
Summer Solstice
Shade/Sun Conditions Summer Solstice 12:00pm
Lack of tree canopy and shade structures leaves the plaza fully exposed to sunlight during the summer months. A large portion of the plaza receives little to no shade throughout the course of a typical summer day which decreases human comfort and increases the urban heat island effect.
Autumn Equinox
Shade/Sun Conditions Autumn Equinox 12:00pm
In Autumn, much of the plaza is exposed to direct sunlight for over 5 hours per day. Structures to the South create shade pockets along the Sears Crescent building where the majority of pedestrian traffic occurs on the plaza.
Winter Solstice
Shade/Sun Conditions Winter Solstice 12:00pm
(hours of shade per day)
Low sun patterns and tall structures to the South create dense shade on the plaza in the winter. Small areas along the JFK building receive less shade than the rest of the plaza. The minimal amount of sunlight combined with winter winds creates an uncomfortable environment.
Spring Equinox
Shade/Sun Conditions Spring Equinox 12:00pm
In the spring, much of the plaza is exposed to direct sunlight for over 5 hours and areas along the JFK building receive slightly less shade. The main pedestrian route adjacent to the Sears Crescent building is shaded for the majority of the day.
View Analysis

Holocaust Memorial The six vertical glass structures of the Holocaust Memorial create visual interest and are visible as pedestrians traverse the northern end of the plaza. The glass structures are illuminated creating interest during the night.
Faneuil Hall Views to Faneuil Hall are present along the south end of the plaza between the MBTA station and Congress St. As a popular destination for tourists and residents alike, preserving these views will help connect the plaza with the surrounding assets of the city.
Old State House The Old State House is visible through the corridor between One Washington Mall and 28 State Street. As a historically significant structure and popular tourist destination, visually linking this element with the plaza is essential.

Stormwater and CSOs
Boston Harbor A combined sewer system is a sewer that combines drainage runoff, domestic, commercial, and industrial waste into a single sewer pipe. During large rain events these systems can become overloaded and discharge untreated sewage into nearby waterways, see figure 1.5. CSOs significantly impact the water quality in local natural waterways and reducing the amount of stormwater that enters a combined sewer system reduces the potential for overflows. In 2013, 500 million gallons of CSO was discharged into Boston waterways. Reducing, reusing, and slowing down stormwater can relieve the burden on the city’s combined sewer system and improve water quality.
figure 1.5 (runoff volume)
Runoff 69
The site produces an average of 12.5 million gallons of runoff annually , or 395,000 gallons of runoff in a 1-inch rain event. 71% of the runoff enters a combined sewer system and has the potential to discharge into the Boston Harbor. Reducing or reusing a portion of the stormwater produced on site will have a significant impact on the amount of flow entering the Boston Sewer System and reduce the probability of combined sewer overflow.

Conceptual Master Plan From our site related bubble diagram we produced a conceptual master plan. We started to give each area a more defined space and ensured our main pathways would be able to serve the plaza’s needs. The shape of each element reflects how it will be placed and integrated on the site and in relation to each element. We each did our own initial conceptual design then came together to produce the final one as seen to the left.

Dilworth Plaza - Philadelphia, PA This plaza sits outside of Philadelphia’s City Hall. As of now it is completely covered with concrete but in 2011 construction began to implement a contemporary redesign. The new design will include an ice skating rink, concert space, open green space, water features, cafes, and new entrances to the subway station. The plan also calls for the reduction of impervious paving, added vegetation, and green infrastructure for water reuse in the water features. This redesign focused on pedestrian centered design and sustainability. This space relates and can be a model for City Hall Plaza in many aspects. The program elements are similar to what we plan to incorporate in addition to the importance of pedestrian and sustainability design.
Plaza de la Constitución - Oaxaca, Mexico This space sits in the heart of downtown in one of Mexico’s larger cities. The plaza has been in existence for over 500 years making it a key study for successful urban spaces. The area provides activities for all ages including open green space, interactive fountains, vendors, daily concerts and fiestas, and the use of vegetation for a comfortable microclimate and safe visibility. Being located downtown, it is surrounded by cultural, civic, and commercial buildings. The plaza is the only large open space in the immediate vicinity which plays a role into its success. In relation to Boston’s plaza, the location and surrounding amenities are very similar. In addition, Mexico’s plaza has been a successful space for hundreds of years, making it evident what people enjoy: water, trees, and activities. Our site’s development can draw from the elements in this space that has made it incredibly successful for many years.

Pioneer Courthouse Square - Portland, OR In the center of Portland is the space known as the city’s “Living Room”. Everyday, thousands of people come and sit on the stairs in the famous plaza space to enjoy the public art and green space. This space has become a major green space within the city while also being a transit hub including a subway station, bus shelters, and bike facilities. This plaza started out as a historic orphan house that transformed into a hotel, and again into a parking lot before the space was used as a plaza. Some of the unique pieces that once stood here have been preserved and reintegrated into the space such as a historic gate from the hotel now used to mark the south entrance to the area. This space is a wonderful example of reuse in an urban setting. This plaza has a rich history similar to Boston’s City Hall Plaza that has been incorporated into the design. These elements give a sense of place and give the plaza character. With the addition of vegetation and a transportation hub this square can directly relate to Boston’s plaza space.
Peavy Plaza - Minneapolis, MN Peavy Plaza once served as the model for all American urban public spaces. Since then it has fallen into disrepair and is in need of a redesign. A new design has been proposed but the historic nature of the site has made it incredibly controversial, as the plaza has been nominated for historic preservation. The redesign includes elements such as water features, summer festivals, winter ice skating, and vegetation throughout the space. As of now the majority of the plaza is made up of concrete and uses very geometric forms in the urban setting. In relationship to Boston’s plaza it is clear that many historic plaza spaces are controversial subjects for redesigns. A contemporary feel is necessary to bring it up to date and to attract pedestrians in the city.

Old Town Square - Prague, Czech Republic This square has been in existence for centuries. It is one of the most successful plaza space in Europe and attracts millions of visitors every year for the stunning architecture that surrounds the space. Some of the attractions include coffee shops, restaurants, street vendors, open space, the famous clock tower, and a rich historic context. The open space that is found here attracts many visitors and the steps surrounding the plaza is always full of people waiting for the clock tower to chime. The culture in Europe is very different than the United States. Overseas, people are more open to the wide space. This may be due to the tight streets that are prevalent in European cities. One aspect that can be applied to our site is the wide variety of amenities that are available. These small attractions can be utilized in Boston to breathe some life back into the space.
The Porch - Philadelphia, PA The Porch sits outside of Philadelphia’s 30th Street transit station. It was once 34 parallel parking spaces that was adjacent to a major roadway. It has since been transformed into a pedestrian destination that includes movable seating, free daily concerts and activities, food trucks, and vegetation throughout. One reason the space is so successful is the large amount of foot traffic that passes through including employees, tourists, and residents. The space is very flexible and lends itself to a wide variety of activities. This street plaza is perfect for looking at transforming a car centered space into a usable pedestrian area. The activities are great for attracting people and getting them outside. The free daily concerts create community involvement and allow for spontaneous interaction. For Boston’s plaza the concepts of movable seating and daily concerts can be great additions to the space. It will ultimately draw people into the space.
design process 46
City Hall Green Roof - Chicago, IL On Chicago’s City Hall, a 110 year old building, a green roof was added for many benefits. Stormwater management, ambient air temperature, and aesthetics all play major roles. The green roof retains 75% of the runoff that is generated in a 1-inch storm in addition to reducing the surface temperature by 70 degrees and the air temperature by 15. Overall the roof improves air quality in the dense urban environment and conserves energy need for the building. This study shows the importance and the ease of retrofitting green roofs on existing buildings. Chicago’s City Hall is 110 years old and the green roof was installed nearly 10 years ago and is still successful. This retrofitting process can be applied to Boston’s City Hall mainly to control stormwater runoff but also for the reduced energy costs.

After developing our preliminary master plan and researching various case studies we reevaluated our design process and focused on a concept driven design strategy. After much deliberation we developed a concept of “movement through space�. This concept drove us to break from our linear thinking strategies into a more dynamic approach. This in turn reflects on the final design solution. design process 48

Final Master Plan Pedestrian Bridge
The final master plan dramatically changed from the preliminary. In the preliminary the overall layout and ideas associated with each program element were satisfactory but, not how they related to each other. From this point the concept was reevaluated and focused on the idea of “movement through space.” The interpretation of this concept was a more dynamic activity than what the initial concentration was. The design transformed from a linear to curvilinear design. The curves throughout the design create a complex range of spaces that intertwine together. Many of the curves were specifically developed to lead peoples’ eye through the space. Leading them into various areas within the site. The curved lines were also drawn from the context of the site. Boston is known for its organic layout. We took this organization and utilized it on site. Many of the context features around the site also have strong curved elements. These elements drove our design process. The site’s spaces range from the necessary large gathering space in the center to many smaller spaces to define that event space. These smaller spaces help to break up the openness of the plaza and give people a reason to use the space when there are no events happening. In addition to creating large and small spaces we also increased the vegetation and tree canopy. The vegetation used will bring biodiversity back to the area in addition to becoming a vegetated link between the Rose Kennedy Greenway and the Boston Commons. Trees are excellent for uptake of water. One mature tree can uptake and evapotranspirate 100 gallons of water a day. The proposed canopy on the plaza will help with the reduction of stormwater in addition to storing 100% of a 1-inch storm underground. This reduction will keep untreated runoff out of the Boston Harbor and reduce the amount of CSO overflow generated every year.

Support Drawings Transportation Hub Thousands of pedestrians and commuters travel through City Hall Plaza every day. The Boston Bike Share station and wayfinding components are important aspects of that community that will guide visitors and residents through the space and provide useful information. One of many stations downtown, the Government Center Station is currently under construction. We drew inspiration from this modern design when we were in the preliminary stages of designing. In addition to the MBTA station, bike share, and information signage there are two bus stops located within the plaza. The proposed stops have overhead canopies and seating that will provide a more suitable waiting area for those using the bus system.
Support Drawings Transportation Hub Tree cover and seating were important features in our design. We wanted to provide enough spaces to ensure the comfort and well-being of the users of the plaza. In our urban tree grove, movable and permanent step seating can be seen. The movable seating allows people to sit, eat lunch, and wait for friends getting off at the subway station. Permanent bench seating is incorporated into the steps to give additional seating and a unique feel. Providing a visual connection to the MBTA station throughout the site was key to linking both sides of the site. This visual connection leads people through the site either towards Faneuil Hall or the main gathering space inside the plaza.

Support Drawings Splash Pads Surrounding the splash pad area are stairs leading up to the street-level pedestrian space. This area provides seating, along with the benches incorporated into the stairs. The multiple levels create different spaces and provide a unique transition from street to open plaza. This space will also be used for daily street vendors, the bi-weekly farmers market, and event space during concerts. Pedestrian interaction is an important concept for the proposed plaza. Splash pads are one of those interactive elements that brings people to the plaza not just to pass through, but to spend part of their day. The splash pads run along the edge of the main gathering area giving a purpose to the space when there are no events. This also engages pedestrians as they are walking through the space providing a positive atmosphere.
Support Drawings Transmission Circle There is a unique historical landmark within the plaza, where Alexander Graham Bell made the first ever transmitted sound over wire to his assistant Thomas Watson. The proposed design creates a unique memorial space that celebrates the transmission in a contemporary fashion. Like the LCD wayfinding screens on various parts of the site, these screens display the history of the telephone and how Bell invented it. The interactive screens, when pressed, will bring up various events pertaining to the invention of the telephone. This interactive element will bring a fun educational element to the plaza that will engage all types of people.

Support Drawings JFK Federal Building Front Entrance The northwest street corner of the site does not currently suit the needs of pedestrians. It is used for a construction camp, creating an awkward space that is unpleasant to pass by and view. The entire space is covered with impervious materials increasing the stormwater runoff generated during rain events.
Before
Support Drawings JFK Federal Building Front Entrance The proposed street corner has an abundant tree canopy, mounded vegetation and seating. This establishes a comforting entrance to the plaza and is welcoming to residents and tourists. In addition the space will be more useful for pedestrians. It will help to define the entrance to the building and plaza space. This area creates a softer transition and entices people to move through the space. Stormwater is managed in this area by the vegetated mounds, street trees, and previous concrete pavers.

Support Drawings Information Center Although shady, the northeast street corner does not provide pedestrians with any amenities or attractions. A large wall is observed toward the JFK building, while a railing does not allow interaction with the lawn or vegetation. The transition between the street and space is nonexistent. It is unattractive and does not allow for pedestrians to use the space.
Before
Support Drawings Information Center With the new development across the street from this location, it was important to provide people with wayfinding strategies and a comfortable entrance into the plaza. An LCD information screen can be seen above centered around vegetation and seating. The screen is interactive to the touch and provides information including news, city events and wayfinding. This street corner is far more usable than the existing environment. The seating and wayfinding system will help to smooth the transition from sidewalk to inside the space. The trees surrounding the space will also bring the space to human scale and provide a comfortable microclimate.

Support Drawings Pedestrian Bridge The pedestrian bridge is a main feature within the proposed design. The bridge was developed to meet the finished floor elevations in front of JFK Federal Building and to integrate City Hall with the landscape. The arching form elevates the bridge and creates a dynamic shape in combination with its curvilinear form. When entering the site on the ground level, visitors will feel as if there is a defined grand entrance to the main gathering space. The plants lead the viewer through the space and naturalize the space. On the bridge level the plants transform the space into a more eco-like feel. The plants soften the bridge integrate the buildings and create seating areas within the space. The bridge contains three skylights to enhance the connection between the bridge and ground level ramp. The skylight to the left in the section cut feeds the waterfalls that flow into the interactive water feature. From the same skylight the ripple screen can be seen enticing visitors to explore the site further.

Support Drawings Pedestrian Ramp The connection from the Holocaust Memorial to City Hall Plaza is important in the reconnection of the plaza back into the city fabric. The memorial has a powerful message and we were heavily influenced by its stature. The bridge helps in that connection and continues the powerful sense the memorial brings. The entrance into the plaza from Cambridge Street is a very grand and powerful space. This will draw people into the site and provide a vegetated link between the Boston Commons and the Rose Kennedy Greenway.
Support Drawings Pedestrian Ramp The pedestrian bridge gives the plaza a grand entrance that signifies the importance of the space when first walking through. From this view, the bridge frames the large gathering spaces that includes the splash pads, interactive subway lights and the main corridor water feature. The overhead bridge creates multiple spaces that gives the space a diverse range of areas. The bridge allows for beautiful overlooks into the city fabric while the ground plane frames different views to lead visitors eyes through the space.

Support Drawings Bike Storage Station Boston’s bike community is growing, and with that growth comes a need for bike storage. We came up with a solution for providing this storage, and it’s in the way of this bike storage center. The facility will hold approximately 50 bikes and will provide people with a safe bike storage location.
Support Drawings Bike Storage Station The system works similar to a carousel, going around in a loop. The bicyclist loads their bike into the bin, the bike is then turned upright and is inserted into the facility. The bicyclist receives a ticket with a number, and when they come back to collect their bike the ticket is inserted and the correct bike is returned. This system utilizes the area created from the elevated pedestrian viewing area, making it a multi-use space. Creating a bicycle friendly space will plan for the future growth of Boston’s bicycle community.

Support Drawings Pedestrian Ramp This walkable space gives people a chance for real water interaction. The Ripple Screen and waterfalls go hand-in-hand in providing a space for a small oasis. The waterfalls on either side help to define the main walking path through the water. The path’s rocks are closer together to provide a safe path and break up as they move away to create a range of walkways. The green circles on the main pathway, when stepped on generate electricity and is stored to power the lights of the Ripple Screen. This is a sustainable way to power some of our site features.
Technology Pavgen Pavgen is a technology that uses pedestrian walking to generate and reuse electricity. This technology is many times embedded in pedestrian walkways and uses foot traffic to create electric power. In our water walkway this technology is intended to be used to power the ripple screen. An interactive LCD screen. This feature will bring an additional element to our site design. It will engage visitors and bring an educational component to the design.

Support Drawings Ripple Screen This original idea we incorporated in our design allows an individual to interact and play with an LCD screen. When touched, this “Ripple Screen� reacts by behaving like a waters surface, rippling along with the intensity of the touch. Even when a hand is wiped across this surface, the water reacts similar to the waves behind a boat. This screen will engage visitors and continue the water theme throughout the four seasons. Even in winter when the fountains are shut off pedestrians will still have a reason to come to City Hall Plaza.
Technology Float 4 After developing our ripple screen concept we searched for similar products to ensure that the concept was feasible. We discovered Float 4 a company that specializes in interactive screens. The company has many different scenes that can be programmed into the screens including some games such as soccer. This company’s technology could be applied directly to our ripple screen to enhance the users experience through the plaza.

Support Drawings Pedestrian Ramp The pedestrian ramp is the main solution to addressing the grade change on the plaza. The ramp itself is only a 4.9% slope making it comfortable for everyone to walk up. The ramp is an incredible large feature within the space so vegetation and earth mounding was added to soften the space and to provide a vegetated link between the Rose Kennedy Greenway and the Boston Commons. The trees used are suitable for urban environments and bring the scale of the space to human level. The native shrubs, perennials, and groundcovers will provide four season interest for people to enjoy. The walls on either side of the ramp make up the grade needed for the finished floor elevations and the pedestrian bridge. The urban tree groves on either side soften and integrate the buildings with the landscape. The tree groves throughout the site are left open underneath for visual connections between the plaza spaces, seating areas for pedestrians, and also for concert space. Attendees will be able to sit under the tree groves and still see what is happening on stage.

Support Drawings Pedestrian Ramp With the large elevation change that occurs in the plaza, the biggest challenge was to create a space that was ADA accessible and could be easily walked by all age groups. Currently stairs plague the plaza; although, in the proposed design ADA accessibility is the primary route through the site. In doing so, it became much easier to incorporate interactive features and practice strong stormwater management strategies. The entrance shown below showcases the entrance from the bridge to the main gathering space in the plaza. The bridge frames the view and leads people into the area. The vegetation on either side soften the ground plane and give a naturalized feel to the plaza.
Support Drawings Pedestrian Ramp The stormwater feature along the main ramp corridor allows for soothing sounds of water to flow out into the plaza. This water is reused stormwater that is collected and cleaned before being used for features such as this. This water feature will provide a natural system to the plaza that will encourage visitor interaction. The walls are low enough to allow anyone to interact with the water and the vegetation around it enhances the natural feel and invites wildlife into the space along with people. The idea of water is a connecting feature within the plaza. Using recycled stormwater we ensured to manage our water usage and manage runoff.
support drawings 76
Support Drawings Pedestrian Bridge Visual connections are important in the plaza’s function, as it is a node in the heart of the city for pedestrians to either stop or continue on to their destination. The Holocaust Memorial is one of those key features near the site. In the current design the memorial is very clear to see. This is largely due to the emptiness that makes up the plaza. There is no sense of mystery and it seems to just be an extension of the plaza with no connection.
Before
Support Drawings Pedestrian Bridge Keeping within that necessary visualization, we designed a pedestrian bridge and smooth walkable path that highlights and brings out the importance of the Holocaust Memorial. The bridge provides a visual connection both on the ground plane and on top of the bridge. This visual link designates the areas as two separate spaces but keeps the connection. The tree grove is open underneath for many reasons. The first being continuity, this space was intended to give a repetitive element through the plaza to lead people through the bridge, this is also achieved through the paving pattern on the ground. The tree grove also allows for seating where people can come to sit, eat lunch, and people watch. This area was intended to host passive recreation. Stormwater storage also occurs in this space. Underground storage chambers allows us to capture, store, clean, and reuse water that would otherwise flow into the Boston Harbor. The space also maintains a connection between the upper and lower portions of the site design. The glass railing keeps visitors engaged with the rest of the site and provides unique views of the site design and surrounding architecture.

Support Drawings Pedestrian Bridge The most unique and powerful area in the plaza is the pedestrian bridge that stretches between the JFK Federal Building and City Hall. This bridge provides an opportunity for social and environmental interactions, along with views of historical features. The historic features around the site give a strong sense of place and it was incredibly important to maintain that sense in the redesign. The bridge design was developed with ecosystem biodiversity in mind. The native plant palette will attract wildlife and provide a vegetative link between the Rose Kennedy Greenway and the Boston Commons. In addition to this design element we ensured the bridge clearance was high enough to allow emergency vehicle access; a necessary function for the plaza.
Support Drawings Pedestrian Bridge Glass railings on the pedestrian bridge allow people a chance to view the spaces down below. It provides unique views to this amazing structure while also creating additional spaces. The skylight as shown below allows people to see the ripple screen and waterfalls. These visual and auditory amenities will keep people engaged in the site and drown out some of the common city noise pollution. On the upper portion of the bridge the vegetation softens the bridge and the green wall in the back reduces the amount of brick that is visible on City Hall. The green wall planting arrangement undulates to lead people through the space. City Hall has also been vegetated to soften its brutalist style and integrate it with the plaza design.

Support Drawings Secondary Entrance With the new development beginning just north of the site, it is vital to create easy pedestrian access. A sealed breezeway joining the two JFK buildings cuts off a necessary approach when traveling through City Hall Plaza.
Before
Support Drawings Secondary Entrance Replying to the new development, we are proposing to open up this corridor by eliminating the building connector. This does not alter the function or use of the buildings, and provides easy access between the plaza and redevelopment. The connector on the 3rd story still allows a connection between the buildings.

Support Drawings Main Gathering Space A large open space was necessary to maintain in the redesign. The plaza’s main function is for events so it was imperative that we plan for the largest events it holds i.e. Boston Calling Music Festival and The Big Apple Circus. The event space is more defined than what currently exists. Urban tree groves on either side provide a softer transition and inform pedestrians that they are entering a new space. The urban tree grove to the left is elevated to meet street level. This provides a smooth transition between the street and the interior of the plaza. The tree grove can be used for the bi-weekly farmers market, daily street vendors, and vendors brought in for any of the events. This space incorporates permanent and movable seating to allow for a mixed-use space. From this space the stairs step down to the splash pads. These water features line the event space and provide a use of the open area when there is not an event. Moving to the right of the event space is a planter. These planters are incorporated within the open space and help to soften the expansive area. They can be used for stormwater management and provide seating for those moving through the space. The urban tree grove to the right helps define the space and backs up to City Hall. This placement softens the building and helps to integrate it with the landscape.

Support Drawings Event Panels Events are always happening at City Hall Plaza, and what better way to keep up with them than visiting the interactive event screens. These screens can be programmed with the events and other information that involves the plaza. People can touch one of the advertisements on the screens and additional information will appear. The screens are solar powered and are embedded into wood panels to provide another opportunity for interaction, as they slide freely on wheels uncovering event posters. What once was a overbearing brick wall is now transformed into an event knowledge station. To the right a green wall can be seen. This was used on the walls that did not have event panels. The walls were used to integrate the building with the landscape and to soften the harsh brick. A urban tree grove can be seen to the left which allows people to move freely through the trees and maintains a visual connection from the main gathering area to the event panels.
Support Drawings Events - Boston Calling The primary purpose of the plaza is for events. The largest event held annually in the plaza is the Boston Calling Music Festival. This 3-day event welcomes an estimated 22,000 spectators and brings in dozens of vendors and some big name bands. Providing enough space for this group of people was a priority during the entire design process. In the design a large enough open space for the stage, equipment, and crowd was preserved. The rest of plaza has space for the vendors that come to these events. There would be small pockets of vendors around the tree groves and planters, giving a sense of order to the events.

Support Drawings Events - Big Apple Circus City Hall Plaza is known for its large events and large crowds. One of the main events that occurs annually is the Big Apple Circus. The circus has been coming to the plaza for over 26 years so it was impactive that we maintain the space required for their setup and events. An adequate amount of space is needed for the main circus tent, trucks and vendors. We worked to preserve this space in our proposed design. Vendors can be seen near the planters giving a sense of order as to where they set up during events.
Support Drawings Events - Farmers Market The bi-weekly farmers market events are extremely important to the city as many people flock to the plaza to buy fresh produce. Below the proposed tree canopy is the perfect area to hold such an event, providing an abundance of shade and comfortable atmosphere. The location of the market allows it to be seen from cars on Congress Street and from people walking through the plaza. This position will draw spontaneous visitors and increase the markets’ consumer base.

Support Drawings Large Gathering Space Lighting is important for the safety and aesthetics of the plaza. The lighting of the plaza space will allow activities to continue after dark such as the splash pads. It will also give a feeling of purpose and safety to the space after dark. A unique feature incorporated in the design are lights that react to the arrival of the subway lines. When the blue or green lines are arriving, lights are displayed letting commuters know their train will be reporting soon.
Support Drawings Sears Crescent Connection Preserving the visual connections to surrounding landmarks will help relink the plaza to the surrounding city fabric. The view to Faneuil Hall was a driving force for this area. We were sure to maintain it by careful placement of trees and other design elements. The existing grade in front of Sears Crescent descends to create a recessed area known as the “moat�. Not only is this unsafe but is very unattractive and uninviting for visitors. In the proposed design the grade in front of Sears Crescent is altered to address the issue of connection between this area and the rest of the plaza. The regrading of this space will help link the plaza as a whole.

Support Drawings Sears Crescent Connection Sears Crescent is an extremely famous building within Boston. As of now the area in front of the building is sunken creating a unattractive, unsafe, and unwelcoming atmosphere. The proposed design regrades the area to reconnect it with the rest of the plaza. When regrading we were sure to minimize the amount of fill to maintain the storefront entrances. Only a maximum of three feet of fill was applied to any one area. The storefronts in Sears Crescent will require some shallow window wells and steps to access the stores inside. The reconnection of this space with the rest of the plaza was essential to create a cohesive feel throughout the space. Tree canopy with movable seating was integrated to soften the space and to bring it back to human scale. The trees were carefully placed to maintain the visual connection between the MBTA station and Faneuil Hall. Pedestrian lighting was used to increase the use and safety at night.

Support Drawings Faneuil Hall Overlook This space has been transformed into an area that fully utilizes the connection to Faneuil Hall. The terraces step down to the space, separating it, while also minimizing the wall needed for the underground garage. The grass incorporated into the space gives a softer feel where people can sit and enjoy the views. The existing underground garage entrance has been maintained but reworked to utilize the new curved edge. The redesign ensured the garage could still function as before. The stairs adjacent to City Hall had to be maintained to meet finished floor elevations but we softened and integrated the massive stairs with the landscape by adding vegetation. The view to the MBTA station and Sears Crescent can still be seen here. Views into and out of the plaza were utilized to visually connect the site and adjacent areas.
Support Drawings Stormwater Alley An emphasis on stormwater management was an important aspect of entire site. This area in particular was focused on stormwater management. These flow-through planters will collect stormwater runoff from the site filter it and drain into the underground cisterns. The Old State House has a fantastic historical relevance to the area. A clear view was maintained to create a visual connection between both sides of the corridor. The linear paths of the stormwater planters lead the visitors’ eye through the space and give a focus to the Old State House.

Support Drawings Stormwater Alley Increasing tree coverage was important in making this space a comfortable pedestrian corridor due to the tall structured buildings. The visual softness the trees and vegetation brings is crucial for making it comfortable for people. In addition to the many textures of the vegetation the materials used in this space engage people of all ages. The wood on the ground plane and the benches give a natural feel and the pavers and clean lines keep the space contemporary. Movable seating was a main component in the alleyway due to the businesses and cafes in the adjacent buildings.
Support Drawings Stormwater Alley Lighting is a meaningful and necessary component of the overall site design. The overhead lighting in this alley gives an overhead plane and assists in the creation of a comfortable pedestrian space. The zig-zag pattern illuminates the entire space. The lighting located within the bench seating and trees will provide a safe atmosphere the space at night. This will enhance visibility and provide another unique lighting solution.

Stormwater Alley The section cut shown to the right explains the stormwater alley planters. These planters are below the surface but the vegetation grows to meet the main ground plane. The trees on either side soften the skyscrapers and bring the scale to human level. There are also overhead lights that zig-zag across the alleyway to create a ceiling plane and to provide overhead lighting at night. Movable seating can also be seen in front of the different storefronts and cafes that are in the buildings defining the alleyway. The proposed design utilizes stormwater management, brings the space to human scale, and uses vegetation for aesthetics. These elements are crucial when creating a space people will want to utilize.

Planting Design Planting Design The planting design we propose is a very complex natural organization style. The plants were specifically chosen because of their tolerance to urban conditions, four season interest, and native status. The planting design was developed to create a link between the Rose Kennedy Greenway and the Boston Commons. This link in the center of downtown is vital in increasing biodiversity and connecting Boston’s park system. The chart on the right shows the color, duration, and time of year each plant bloom. The plants chosen create a dynamic planting design that is sure to have interest throughout the year.

Stormwater Management
The stormwater plan shows the various stormwater Best Management Practices used to reduce the amount of runoff generated by the plaza. Over 90 percent of the plaza is connected to a combined sewer system making the reduction of runoff imperative to improving the water quality of local waterways and the Boston Harbor. The existing plaza design is 99 percent impervious and generates 52,773 ft3 of runoff in a 1-inch storm. The new design and stormwater system is capable of storing and infiltrating the first 2 inches of rainfall on-site.
Stormwater Management Bioretention Bioretention areas on the North end of the site collect surface runoff from the new drop-off circle in front of the JFK federal building. Bioretention areas act as soil and plant-based filtration devices that remove pollutants through a variety of physical and biological treatment processes. Although the Northern end of the site drains to a separate sewer system, the ability of bioretention areas to reduce pollutant loads to receiving waters is necessary towards achieving regulatory water quality goals.
Subsurface Infiltration Subsurface infiltration tanks are designed to temporarily hold and infiltrate stormwater below the surface of the plaza. Surface runoff and overflow discharge from stormwater chambers drains to the infiltration areas where the water has the opportunity to percolate into the ground. Infiltration is a vital aspect of stormwater best management practices because it allows water to recharge local groundwater systems.
Stormwater Chamber The stormwater chambers collect surface runoff and overflow from the retrofitted green roofs on City Hall and the JFK Federal Building lower wing. The chambers store stormwater which is reused to irrigate the trees and green walls on the plaza. Irrigation is imperative to the health and quality of urban trees and will aid in the long-term success of the plaza. The trees offer opportunity for uptake and evapotranspiration which reduces stormwater volume and assists in the cooling of the surrounding area. The chambers have the ability to store up to 3.14 ft3 of water per linear foot. Overflow from the chambers enters a subsurface infiltration area where the water is provided with adequate space and time to infiltrate into the ground.
Storage Cistern Many areas of the site are obstructed by subsurface infrastructure (subway tunnel, parking garage, etc.). Due to subsurface limitations in these areas the infiltration of stormwater is not possible. In this case, surface runoff is collected and stored in cisterns. The stored water is reused for on-site water features and irrigation.
Flow-through Planter Due to subsurface limitations, flow-through planters were utilized in multiple areas on the plaza. Flow-though planters reduce stormwater flow rates, volume, temperature, and improve water quality. The planters also provide opportunity for uptake and evapotranspiration which reduces stormwater volume and aids in the cooling of the surrounding area. stormwater management 102
Stormwater Management Integrated Stormwater System The integration of various stormwater techniques creates a stormwater system with a maximized potential to reuse, infiltrate, and store stormwater on-site. The section diagram (right) shows the integrated system and provides an understanding of how the system will function.
