Introduction Tysons Corner is undoubtly a very exciting and increasingly complex edge city which will experience dramatic growth, opportunity, and diversity. Future development will require a wide range of knowledge, considerations, and design strategies to provide cohesive solutions. Tysons Corner is to receive four Metro stations which will ultimately give life to a new identity and respect to Tysons through advances in economical, environmental, and social aspects.

The first phase of this document will define the scope of the project, existing issues, and projected issues. Tysons Corner is not only known for its reputation as a business destination but also for its lack of pedestrian friendliness, traffic problems, and non existent sense of place and/or identity. The second portion of this document will begin with an understanding of the design process and conceptual solutions. Due to the complexity of Tysons Corner many aspects must be carefully thought out from all angles to provide solutions that address the issues as a whole. The last section of this document will show case the final solution and supporting documents. With Tysons Corner’s extreme complexity it is imperative that all issues are addressed as a whole. The final solution may not fully relieve every issue but the more intensely weighted issues will prove the forefront to the solutions intentions.


Design Intent The overall scope of the project is to develop a master plan that addresses and relieves existing issues as well as satisfying the future needs of Tysons Corner. The design will be focused on the Central 123 Metro station which has potential to become the central core for Tysons. The solution will embrace landscape architecture methodologies by use of careful planning, integration of sustainability, and providing a central green core. One of the biggest challenges that must be satisfied is to establish a sense of place, identity, and character to Tysons Corner. In order to achieve this goal careful planning will identify itself as the backbone by creating pedestrian friendly block sizes, efficient vehicular routes, and ample urban oasies that function with proposed densities. Many sustainable techniques will be implemented into the design with a focus on stormwater, water re-use, and energy production/ conservation. A central green core has an incredible amount of potential at the Central 123 location because of its undeveloped landscape and location to core amenities Tysons Corner offers such as the two iconic shopping malls, Tysons I and II. A green core will bring a sense of place and a place of destination on the environmental front to Tysons by weaving nature into the urban fabric.


Mission Statement The project purpose is to transform Tysons Corner from a structural and vehicular dominated region into a pedestrian friendly urban core which will support future growth. Connecting the Central Metro station, shopping malls, and office buildings by use of a green network will bring a sense of place and community to Tysons. A green central core will serve as the main thoroughfare by emphasizing the importance of pedestrian based circulation while simultaneously relieving vehicular congestion. The outcome will create a desirable urban center that will provide exciting public vistas, a lively community, and a new connection to the existing environment.

History Tysons Corner began its developed life as a crossroads of route 7 and route 123 with a general store. On July 25th, 1968 the Tysons Corner shopping center opened and at the time was the largest indoor shopping mall in the world. This established Tysons as a premier shopping destination. The following years many Fortune 500 companies have called Tysons Corner their home by defining their head quarters here. By 2010 Tysons Corner contained a quarter of all office space in Fairfax County. Looking forward, in 2014 the four Metro stations coming to Tysons will become active. fig 1.3 (Timeline)

Future growth should aim to make Tysons a livable community while maintaining the reputation of a premier shopping and business destination.

Proximity The proximity to the Metro station will define the density and land uses for that location. The highest density of development will occur within the 1/8th mile radius with a projected density between 3.5 and 5.0 floor to area ratio (F.A.R.). The 1/4 mile radius will have a density between 3.0 and 3.5 F.A.R. The 1/2 mile radius will contain a F.A.R. between 1.5 and 3.0. The land uses for each area will be shaped by the F.A.R. where the tallest buildings near the Metro are likely to be office use while lower density areas will most likely be potential residential locations. fig 1.4 (Metro Proximity)

The area highlighted in green represents the focus of our development. The density rings in relation to our site is depicted by the red rings.

Districts Tysons Corner is broken down into five districts, each having its own representation in Tysons. fig 1.5 (Tysons Districts)

1. This location is home to over half of Tysons entire retail floor area. 2. This district contains two subdistricts, separated by Route 7. The north subdistrict is envisioned to be a vibrant 24- hour mixed use center with residential, retail, and hospitality uses as well as a high concentration of office space. 3. This district is a gateway to Tysons from Route 7 and the Dulles Access Toll Road. 4. This area is mainly dominated by residential and business. It is also a gateway into Tysons Central 123. 5. Tysons East serves as a signature gateway for those entering Tysons Corner from the east.

Existing Land Use fig 1.6 (Existing Land Use)

Tysons Corner is currently dominated by business oriented land use. Tysons Corner is highly impervious due to the extreme growth beginning in the 1960’s where green space and ecology was not weighted as it is today. Recently Tysons Corner has begun diluting the amount of business oriented development by bringing in more residential land uses. The future of Tysons Corner should retain its reputation as a business oriented development while mixing in other land uses such as park space, retail, and residential. This would create a dense mixed use community that will help Tysons Corner thrive in many aspects.

Existing Buildings fig 1.7 (Existing Buildings)

The Tysons II Mall is bordered by five buildings. Four of the five buildings are office buildings with one of the buildings being the Ritz Carlton hotel. These buildings help define the architectural style of the site. Buildings labeled two and five are both relatively new buildings and show the desired architectural style for the area.

Existing Access Points fig 1.8 (Existing Access Points)

Tysons Corner lacks pedestrian friendliness as a whole and the Tysons II Mall is no exception. As shown in the graphic below Tysons II Mall is surrounded on all sides by parking garages besides the once access point by the Ritz Carlton hotel. Currently pedestrians who are coming to Tysons must navigate through parking garages to enter the mall from both the first and second floor entrances. The issue is not only geared towards the lack of accessibility but also geared towards the sense of place and aesthetics. The Tysons II Mall is considered a high end desired shopping center and should welcome visitors with an equally matched reputation. The outdoor dining areas located along the first floor of the mall are completely shaded by the massive parking structure. Decreasing the parking garage located to the east and providing pedestrians with a more friendly environment to the mall will be extremely beneficial and become a more inviting place for visitors.

Existing Access Points fig 1.9 (Tysons II Stores)

The Tysons II Mall is considered a very high end shopping mall. The shopping mall consist of three floor with a variety of shops and restaurants. Typically visitors will see stores such as Gucci, Louis Vitton, and Hugo Boss. Visitors will also typically see luxury automobiles such as Ferrari, Lamborghini, and Maserati. The Tysons II mall is layed out very linear and anchored by Macys, Saks Fifth Avenue, and Neiman Marcus.

To the left of the section is the location of International Drive and the existing parking structure adjacent to the mall. Clearly shown in this graphic is the height relationship of the Ritz Carlton hotel to the surrounding landuses and landscape. This sections shows one of the most important topographical characteristics on the site. Located by the forested region of the site is the only extreme change in topography which is an elevation change of roughly 4550 ft in height. Working with this topography will be a key aspect to the overall design.

Green Spaces fig 1.12 (Existing Green Space)

Tysons Corner is dominated by impervious surfaces which is mainly due to large surface parking lots and building footprints. The area has four main locations of existing green spaces. One of the locations is located directly on the site of the Central 123 Metro station. This area proves to be a key potential location for the development of a central green space on the ground plane.

The sidewalks are buffered by a landscape panel with street trees for canopy cover. Photograph 2, 3, 4, 5 - These images show the green space located near the Metro station. This location is one of the few green areas that is located on the site. This location is one of the first places visitors on the Metro will see when arriving at the Central 123 Metro station and will be a key potential viewshed to take advantage of.

fig 1.18 (Route Types) Vehicular traffic and congestion is a main issue. The orange routes represent the common business traffic route, red routes are main thoroughfares, and the blue route is the Capital Beltway I-495. Most congestion occurs in rush hour times due to large amounts of vehicles traveling to and from the main routes from the orange labeled routes. fig 1.18 (Route Types)

fig 1.19 (Pedestrian Routes) Although Tysons Corner really has no form of pedestrian circulation or friendliness, we found that these routes are ones pedestrians are likely to take around the mall area. The existing sidewalk conditions do not allow for walkable ease and the large roadways with moderate speeds make traveling by foot even harder.

fig 1.19 (Pedestrian Routes) fig 1.20 (Route Types) This graphic breaks down the routes into classifications as well as showing where the four proposed Metro stations will be located. For Tysons to become a more walkable and pedestrian friendly place, local roads need to become integrated into the smaller block sizes.

Degree of Traffic fig 1.21 (Degree of Traffic)

The figure below illustrates the areas of common vehicular congestion. The existing traffic conditions on site are very abnormal when considering the high concentrations of traffic in certain areas and other areas at the same time are completely absent of traffic. Most of the traffic on site occurs at the intersection of Galleria Drive and Tysons Blvd. shown by the two left turn arrows at the center of the graphic. This location hits peak traffic from 4pm-7:30pm during business days. Weekend traffic is typically not an issue as the cause of this traffic is mainly due to individuals coming or going from work.

Sun and Shade fig 1.22 (Sun and Shade)

Sun and shade patterns will significantly influence design ideas and help locate key potential areas for green space. The proposed building heights will pose a large challenge when considering the direction and size of shadows they will project. Currently, the back half of the site becomes largely shaded due to the existing hotel and office buildings on site. Though in summer months and times from noon-2pm shade is not an issue. The time of noon2pm is the time frame where green spaces and urban plazas hit peak usage.

Conceptual Building Heights fig 1.23 (Conceptual Building Heights)

Based upon the Tysons Corner Comprehensive Plan there areas of desired density and correlating building heights. This graphic depicts the general building heights for the site. The red area indicated buildings near the range of 225’ to 400’ in height. The yellow area is desired buildings within 175’ to 225’ in height. These heights are desired heights for these areas and may fluctuate in the actual design. These heights will most likely be met in order to attain the desired F.A.R. thresholds for the 1/8 mile, 1/4 mile, and 1/2 mile radii.

Aspect fig 1.25 (Aspect)

Aspect will play a large role when it comes to the design phase of the project. Because Tysons Corner is very dense and proposed to become even more dense, shade patterns will become a key player in the planning process. The east portion of the site is almost completely in the cold/shaded range. Raising the ground plane in these areas will help but a big factor to consider in future development is building heights and shadow projections.

Key Concerns fig 1.26 (Concerns)

The site can ultimately be broken down into five main areas of concern. The largest concern being the existing intersection of Galleria Drive and Tysons Blvd. Another key area of concern is the existing parking garage for the Tysons II mall. This monumental parking garage is completely impervious and serves as a monolithic structure holding back the malls full potential. The whole front half of the mall is hidden by this massive parking garage. Another issue is the lack of entrances to the mall from the eastern side of the site.

Context • Land use • Existing Buildings • Section Cuts • Green Space • Sensory • Circulation • Sun and Shade • Topography • Concerns/Opportunities • Composite

Key Opportunities fig 1.27 (Opportunities)

Many of the concern areas also serve as key potential areas for opportunity because of the intensity of these issues. A key opportunity area that is not a concern area is the threshold of the Metro station located at the intersection of Tysons Blvd and Rt. 123. Connecting the Metro station to pedestrians and surrounding uses will be one of the largest goals of this project. Another key opportunity is utilizing the existing vegetation in the forested area. This area contains healthy mature trees which should be implemented into the solution.

Sensory Composite fig 1.28 (Sensory)

Overall the site is very noisy mainly the sounds associated with vehicles. The only quiet location is the existing forested area which significantly tones out the sounds from vehicles. The site currently feels very open, uncomfortable, and intimidating. It is extremely hard to walk through the site and is very vehicular dominated.

fig 1.27 (Sensory)

27


Context • Land use • Existing Buildings • Section Cuts • Green Space • Sensory • Circulation • Sun and Shade • Topography • Concerns/Opportunities • Composite

Composite Analysis fig 1.29 (Composite)

The site is very vehicular dominated and very intimidating for pedestrians. The location of the future Metro station will pose as one of the largest opportunity areas on site and is an area that should be very well thought out and with pedestrian friendliness as the main goal. The Central 123 station is the location where a large central green space will have the most potential. Circulation is the largest issue on the site, changes to the existing street network should be highly considered. The office buildings located on the site do not fit within the proposed architectural context in function and style. The Central 123 location has great potential to become one of the main destinations in Tysons Corner.

Concept Relationship Diagrams fig 2.2 (Concept Relationships)

The mixed use in Tysons Corner calls for many different types of uses and types of relationships to be met. In order to easily understand how these uses and relationships need to work together, concept relationship diagrams were developed. Some of the key features that are heavily weighted in all three of these options is that the common green would be a central bondage to other uses, the metro would also be a key node of connection, and that there would be integration and separation of residential units to other development. The mall was not a large driving force in these diagrams because the mall is extremely high end and not an everyday destination for common shoppers or residents.

Site Related Diagram fig 2.3 (Site Related)

The site related diagram is based off of the concept relationship diagram number three. The concept is still very basic but the general outline of uses is there. This diagram also gives a sense of how the site would work just based upon the spatial relationships of the uses.

Program Sensitivity fig 2.4 (Program Sensitivity)

Once the uses were spatially observed and developed, the uses were weighted upon their relation to public or private function. The common green serves as the public connector to uses. The Metro serves as the semi-private connection with parks and open green space on the extreme public and office and retail on the extreme private end. This diagram helps to understand the basic connections that should be made between these uses and how they should connect.

Case Study

Harvard University Cambridge Campus, MA

Michael Van Valkenburgh Associates inc.

One of the defining attributes of Harvard’s Cambridge campus is the way that it has grown organically over time without a strong unified vision. The campus today presents a mosaic of complex and somewhat varied conditions, and MVVA’s approach to creating common spaces built upon the stength of that variety. Although the pieces of the campus mosaic all work together, each has unique characteristics necessarily repeatable or dependent on the composition of the whole. Understanding and curating this mosaic, including its unexpected adjacencies and patterns of use, was essential to developing common spaces that were appropriately located, deisgned, and programmed. The sites identified to be developed further as common spaces comprise a family of very different places, each of which has the potential to cultivate a part of a wid spectrum of social needs on a campus. This decentralized, diverse, yet integrated approach to creating common spaces was not only a realistic way to encourage social growth, but it was also one tailored to Harvard’s decentralized prganization. The process began in tyhe summer of 2009 with the installation of seasonal chairs in and around Harvard Yard to encourage new uses.

The Park At Lakeshore East Chicago, IL Six acres of serenity in the heart of the city, the magnificent park at Lakeshore East is the centerpiece of the community and the epi-center of the Magellan Spring Half Marathon and 10k. This virtual botanic garden designed by world renowned landscape architect James Burnett together with Chicago’s Site Design Group was officially dedicated to the city of Chicago by Mayor Daley and other city officials upon completion in 2005. A blend of stairway terraces, sidewalks, cast green spaces, interactive and aesthetic cascading water elements and intimate gardens, this oasis in the heart of downtown is rapidly developing a reputation as the biggest and best front yard in the Chicago metropolitan area. At night the park illumination is a light show highlighting the unique navigational patterns of the design of pathways, the grand staircase and the back lit mystical flowing waters.

Case Study

Teardrop Park New York, NY

Teardrop Park is a 1.8-acre public park in lower Manhattan that transcends its small size, shady environment, and mid-block location through bold topography, complex irregular space, and robust plantings. Teardrop’s design and construction were coordinated with the development of four surrounding apartment buildings, each ranging from 210 feet to 235 feet in height. In the development of Teardrop Park, sustainability was not merely a goal, but rather an organizing principle that influenced everything from material selection to contractor practices. Based on decades-long research into urban soils and non-toxic plant maintenance, environmental aspects of the park’s design include fully organic soils and maintenance regimes that don’t rely on pesticides, herbicides, or fungicides. Treated and recycled graywater from the adjacent LEED Gold-rated Solaire Building and stormwater runoff from the site are captured in an undeground storage pipe supplying all of the park’s irrigation needs.

Case Study

North Grant Park Chicago, IL The renovation of Chicago’s North Grant Park will introduce new types of parks and landscpae experiences. The new park will feature a topographically varied landscape and a robust planting palette that includes both deviduous and evergreen trees. A mahor recreational network running diagonally between the Northeast and Southwest corners of the site will include a unique play garden, climbing park, and seasonal ice-skating loop. In addition a network of interweaving trails and diverse landscape views will be choreographed around a continuous lawn valley that runs the length of the opposite diagonal, complementing destination programming with the potential for a lengthy and peaceful, recreational engagement with the openness and greenery of the park. Connected to Millennium Park by the BP Bridge, the ice-skating ribbon will be dramatically different from typical civic ice rinks, creating an experientially rich multisensory activity that is integrated into the landscape, and into the city. Set amidst evergreen trees, the setting creates an illusion of a serene forest setting. At the same time, the sparkling backdrop of the city will provide a reminder that moments like this are part of the unique glamour of cities like Chicago.

Conceptual Sketches In order to visualize the site we needed to sketch out ideas to better understand the atmosphere and how social interaction would blend with the compacted vehicular streets. fig 2.5 (Grid Layout) The

idea of implementing the grid layout to Tysons. It will enforce connectivity and give a sense of character to the area of Tysons. This will also help by decreasing rush hour traffic and increase development by utilizing the proposed blocks.

fig 2.6 (Metro Station Connection to the Mall)

Creating a key connection from the Metro Station to Tysons II Mall is important. Implementing a pedestrian bridge will create a safe and easy route to the Shopping Center and will provide less traffic build up along Galleria Drive.

fig 2.7 (Shops and Restaurants on Street Side)

Store front shops and restaurants along the street will provide an area for pedestrians to walk and visit . This will be blended into the mixed use offices and residential buildings. Creating a connection between vehicles and pedestrian traffic is a key element to the success of the design. fig 2.8 (Street Scape) Incorporating on street parking along a buffered strip will provide a safe area for pedestrians but also add green to the street and provide sufficient shade. fig 2.9 (Birds Eye of Grid and Density)

fig 2.7 (Shops and Restaurants on Street Side)

This is a view of the south east portion of the site. Based on the projected density required for the Central 123 Metro station this vicinity will be highly developed. By implementing a gridded plan to the region it will help with orientation and way finding. The intersections will give choice and directness of route to desired destinations and also defined blocks will form a stronger connection for Tysons Corner.

Conceptual Sketches fig 2.10 (Globe Water Feature)

Storm water management will be utilized through water features proposed on the common green. A key idea for this design is to allow the water to used as a fun, interactive art piece which will aerate the water but also allowing the overflow to be directed to an irrigation system that will be sent to the future vegetation on the green. fig 2.11 (Connection From Common Green to Mall)

Designing curvilinear forms to the main entrance of the common green creates a strong connection to Tyson II Mall and the Ritz Carlton. Incorporating shops and restaurants along Tyson’s Blvd will give a strong edge to the green and also provide an area for people to enjoy. This area will be primarily residential along with a hotel.

The main feature of the common green will be the interactive splash pad that will provide for storm water management. In the winter this region will be used for an ice skating rink so people can enjoy the area during every season. fig 2.12 (Splash Pad)

fig 2.13 (Common Green Space)

This sketch is understanding the connection between the open green space and the high density located in the horizon. The common green will be located on top of a large three story parking garage that will blend properly with the existing and proposed structures. fig 2.13 (Common Green Space) fig 2.14 (Waterfall Feature)

The waterfall feature will utilize the top of the parking garage and common green and flow down to West Park Drive. This provides a strong element to the area and will create a serene state of mind to block out the busy traffic noise.

Preliminary Master Plan fig 2.15 (Preliminary Master Plan)

The preliminary master plan illustrates how putting a grid system into the site will enhance the region creating a functional urban core that the city does not have. The grid layout will provide sufficient block spaces that will hold the proposed high density coming into the site. Gridding the area will also help maintain traffic flow and allow pedestrian accessibility throughout the site. Proposing to take out Galleria Drive will allow a strong and safe correlation for pedestrians wanting to enter or leave from the Central 123 Metro Station to the Tysons II Mall. Located North of site is the proposed common green. This area will be primarily high end residential use and the common green will be located on top of a large three story parking garage. Creating the green core will enhance the site and create a overall link for the area.

Concept for Metro Plaza fig 2.19 (Concept Metro Plaza)

The Central 123 Metro Station will become a key feature to this unique area of Tysons and visitors should be welcomed by an equally unique park off the Metro. The design extracts inspiration from the proposed density rings and celebrates the historical crossroad significance of Rt. 7 and Rt. 123. The diagonal paths represent the crossroads of Rt. 7 and Rt. 123. The circular forms represent the proposed density while the vegetated areas at the center signify the life that the Metro will bring to Tysons Corner. The proposed vegetation will contain material that changes throughout RESIDENTIAL OFFICES the seasons providing a unique sense of place year round.

The concept of linear plaza comes from the curvelinear forms of the common green and the consistency of the grid. This location is a key threshold from the east portion of the site to the common green. The design features terraced lawns and water features. The tiered forms of the design provide passive seating areas for people to congregate and relax.

Final Master Plan The final master plan provides idealogical solutions to environmental, social, and economical needs of Tysons Corner. The plan highlights a dense core directly adjacent to the Central 123 Metro station. In this core area the design features building footprints for three signature high rise office buildings, relative mixed use buildings, and key connections from the Metro to the design as well as existing features. One of the most important concerns and solutions in this core area is providing a pedestrian safe and efficient access to the existing first and second floor entrances to the Tysons II Mall. The design features elevated walks, stair plazas, elevators, sheltered walks, and large outdoor sidewalks radiating from an iconic Metro plaza space to accomplish this solution. This also allows for a unique experience for visitors to move through out the site and promotes pedestrian walkability in an exciting way. The Metro plaza also provides a key connection to the eastern portion of the site linking the two spaces by fluid forms and walk ways. The eastern portion of the site first features a naturalistic trail that weaves in between the Metro track supports. The trail system begins at the Metro station linking the Metro plaza to a community gathering space, continuing northeast to an open green space, wetland and ending at the common green. A compact grid layout in this eastern portion of the design is purposed for pedestrian friendliness. The compact grid is comprised of small block sizes that are an average of 250’ to 400’. The grid design will also play a key role in vehicular circulation by utilizing slower design speeds and a sustainable network in terms of connectivity. The final feature for this location is the constructed wetland which is designed with dry ponds, bio retention basins, and a large signature wetland area with a fountain. This area is designed to be a desired destination for passive outdoor recreation as well as to store, treat, and offset stormwater runoff capacities. The northeastern portion of the design encompasses a wide variety of features with the focus on the large green space which is referred to as the common green. The separation of the common green and the grid will become oneof the main travel ways of the existing congested traffic. This location implements a large two lane traffic circle to keep comstant flows to help aleviate congestion. The grid axis intersects the middle of this proposed road way and declines down into the common green’s parking garage. The common green is one of the most exciting features of the design as it plays a huge role in connecting people, uses, and the urban fabric back into the environment. One of the most interesting aspects of the common green is that it takes advantage of the existing topography by incorporating a three level parking garage below the green space which is at grade with the existing Tysons Blvd. The south west entrance to the common green is the main pedestrian entrance and also ties into the existing plaza at the Ritz Carlton hotel. The common green provides three main entrances for vehicular circulation into the parking garage which can hold a capacity of roughly 2,360 cars. The common green is the primary location for residential uses and features three signature high rise residential buildings. Tysons Blvd becomes lines with small shops and restaurants with a vibrant streetscape atmosphere. The common green itself provides a wide variety of uses, recreational activities throughout all seasons, and implements stormwater management practices. The sites project boundary is 2,440,121.94 sq ft. The green space which includes green roofs, parks, and reforrested areas in the design comes to 1,358,566.02 sq. ft. The overall design maintains a green space percentage of 55.6%. The design meets the needs of Tysons Corner while maintaining a significant portion of the green space. 75

The graphic to the left depicts the proposed floor to area ratio’s for the density rings of 1/8 mile (top), 1/4 mile (middle), and the 1/2 mile (bottom). The F.A.R. for the proposed densities helped push the design strategies and gives a nice stair step environment to the buildings as they get further from the Metro station. This helps bring a more human scale feeling to the common green area while providing a skyline look to the grid and more dense areas. 1/8 Mile

Circulation Patterns fig 3.2 (Vehicular Circulation)

The final circulation patterns for vehicular traffic are depicted in the graphic to the left. The indicator one is the bridge over Rt. 123 that connects to the Tysons I Mall. Indicator two is the intersection of Tysons Blvd. and Rt. 123. Three is the main axis located within the grid. Four is the proposed traffic circle to help alleviate congestion. 5 is the existing road of Tysons Blvd.

fig 3.2 (Vehicular Circulation) fig 3.3 (Water Circulation)

This graphic shows the process of how stormwater travels throughout the site. Indicator one is the back of the common green which houses a water feature that treats both gray water and storm water. Overflow and sheet flow runoff travel south down the common green towards the splash pad where some runoff can be stored. Overflow in this region will travel to the indicator labeled 8 at the constructed wetland. All runoff on the site will flow in the direction of the constructed wetland. Green roofs and rain gardens will help offset the amount of runoff directed towards the wetland.

This is a typical view of what one would see when looking out of one of the office windows looking down towards the Metro plaza. The Metro plaza uses linear and curvlinear paths to bring together the forms and signficance of the plaza. Each planted circle represents each of the four Metro stations coming to Tysons Corner. The circle second from the left in the image represents the Central 123 station. The two linear paths that intersect this circle represent the historical significance of the cross roads of Rt. 7 and Rt. 123. The curvlinear paths represent the fluid forms of nature weaving into the urban fabric with purpose.

This view is extremely important because it is the first thing a visitor would see when coming off of the Metro onto the ground plane. The visitor is immediately welcomed by lush vegetation and way finding signage that promote walking. The bold axial pathway would lead visitors in the direction of the parking garage and Tysons II Mall. The building that is at the terminating end of this path in the distance is the high rise residential building for the 1/8 mile distance from the station. The buildings on either side of this building are two of the signature office buildings. This plaza space is not only a key point for community connection but also serves as a place to meet, take breaks, and relax.

There is a wide range of pedestrian circulation routes near the Metro station. The Metro station will provide entrance and exit points for both ground level and second level. Another aspect to consider is the existing first and second floor entrances of the Tysons II Mall. To tie all of this together the design uses elevated walkways, stair plazas, elevators, and both sheltered and open sidewalks to provide safe and efficient pedestrian circulation. The rendering below shows the stair plaza to the left which has an integrated handicap ramp at a constant grade of 4.2%. In the middle is access to the parking garage as well as the location of elevators. To the right is a sheltered walkway to Galleria Dr. as well as an entrance to the office building to the right. For inclimate weather conditions pedestrians will be able to walk through the parking garage and under a pedestrian bridge when crossing Galleria Dr.

The existing parking garage located to the west of Tysons II Mall has been decreased in footprint size by half and the removed spaces will be added to the northern portion as a third floor. The driving force behind this decision is to create a more pedestrian friendly access to the Tysons II Mall. This space transitions now into an outdoor extension of the mall. This space is intented to be a desired place for a variety of shops and particularly restaurants. The restaurant use in this area will become a popular destination for business lunches, casual meetings, and night life geared towards professionals and mature individuals. The outdoor extension will maintain the existing access points on both the second floor and ground level.

Trail System fig 3.9 (Trail System)

The trail system plays an integral role to tie the features of the plan together. The trail system in on site context begins at the Metro plaza wrapping around the eastern boundary and ending at the upper portion of the common green. The segment of the trail near the Metro station weaves in and out of the large support pillars giving an interaction between the pedestrians and the built environment. The trail is buffered by thick vegetation between Rt. 123 and the southern portion of the trail providing a secluded and naturalistic feeling.

The trail system opens up when it reaches the park and wetland area with a variety of path options. This location of the park serves a main area for passive recreation where people can take part in activities such as catch, bird watching, and relaxing by the fountain. The paths range from 10 to 12 ft in width to give plenty of room for cyclists, runners, and walkers to use the trail comfortably. The existing location of West Park Drive borders the wetland with breaks in vegetation along the main sidewalk to provide scenic views for motorists.

The buildings to the right of the image are all office use buildings except for the building with the brown accents which is a residential building that overlooks the wetland and park area. The constructed wetland is an integral part of the design environmentally as it provides a place for aquatic life, birds, and other species to flourish. This area is also designed to store and treat all of the runoff from the grid. This is possible by the stormwater offset provided by the green roofs which are able to retain an average of 65% of the runoff that falls on them.

Common Green fig 3.12 (Common Green)

The common green is designed to serve many functions on the same footprint. The bottom of the image below is the location of the existing Tysons Blvd. This area currently contains a steep slope with an elevation change of roughly 50 ft down to West Park Drive. The idea of the common green is to take advantage of the existing topography to create a three level parking garage with the common green on the roof level. The common green will then be level with Tysons Blvd. and will also meet grade at West Park Drive with entrances into the garage. The three buildings at the top of this image are high rise residential buildings with more residential buildings to the left. To the right of this image is the proposed hotel to accomodate for the increased development and business oriented grid. The pools to the left of the common green work both as aesthetics as well as a functional gray water re-use system. The water will be filtered through each of the pools before being circulated back into the buildings to be re-used as water to flush toilets, building maitenance, and irrigation for the common green. The middle of the common green serves as all purpose fields and as an event space. To the right is the large plaza that is functional year round. At the bottom of the image Tysons Blvd. becomes an active streetscape with the addition of small shops and restaurants with outdoor dining.
