XIAGUAN SITE MASTER PLAN CONNECTING TO REGIONAL The project site, in the Xiaguan district, sits within an important and prominent location within Nanjing, a city with deep cultural and historical meaning for China. A masterplan for this site needs to not only respond to the unique properties of the site, but posses a sensitivity and understanding of Nanjing’s regional and national context. The Xiaguan site has the potential of not only becoming an important destination and center for the city of Nanjing, but also the Jinagsu Province, the Yangtze River metroplex and the entire People’s Republic of China.

REGION Nanjing sits towards on the western edge of the Yangtze River Delta, one of the most heavily urbanized regions in the world. Though twice the capital of China, the city has been overshadowed in recent decades by Shanghai, approximately 250 kilometers to the southeast. The city of Nanjing proper stretches nearly 150 kilometers north to south with the Yangtze River bisecting the city in the middle, acting as the locus of the most built-out area of the city. The areas farther from the river occupy a spectrum between suburban and more rural areas.
B
The infrastructure of the region points to an important connection for the regions largest cities: Shanghai, Nanjing, and Hangzhou. This trio of cities act as nodes for the regions highway and rail system. Within this triangle lies a majority of the Delta’s urban centers. The rail and road network provide links for those traveling within the region as well as nationally. The High Speed Rail lines connect Nanjing to Shanghai in less than an hour and to Beijing, the national capital, in just over 4 hours.

50km
Nanjing is an important city within one of the most connected and accessible areas in Asia. Additionally, the city and region have seen and continue to see rapid urban growth. This connectivity and intense growth places the city and the Xiaguan site at a nexus of a growing metropolitan complex that continues to increase in importance as a world economic hotspot.

Xiaguan Analysis
CITY The structure of the city of Nanjing represents both modern and ancient forces. During the Ming and Qing Dynasties, the primary ordering force in the structure of the city was the prominent Inner and Outer walls. The area within the Inner Wall remains the core of the city to this day, thanks in part to the preservation of a large portion of the wall structure. The outer wall, long since dismantled, roughly delineates the boundary of the extend urban area. Relationships to the city wall and gates should be considered for future development.
PROJECT SITE XIAGUAN DISTRICT
The city is well connected through a series of rail stations scattered across the urban area. The newly-built Nanjing South Station serves as the primary high speed rail hub, though some high speed trains do stop in the Nanjing Train Station just to the east of the site. The former West Station in the site is no longer in service. Though no metro line currently serves the site, 15 new lines are planned for 2030, with the number 5 line entering the site from the south and connecting the area to the rest of the city. Transit and other mobility connections to the South and Nanjing Stations, as well as the airport in the south, should be prioritized to ensure the value of development on the site. The transit and mobility options on site should fully integrate with the systems of the other important areas of the city. The road network in the city consists of a series of large arterials that make up the primary axes of the city. These arterials can largely be traced to the location of the city gates. Zhongshan Road, running diagonally through the city is a very important road (as the funeral progression for Sun Yat-sen to his mausoleum) and it creates the southern border of our site. The significance of this street should be considered for all future plans. Jiandong Road, running up the western side of the city, adjacent to the Yangtze River, has become an important axis connecting the Hexi New Town to the south with the Xiaguan site and the rest of the city between. This connection should be preserved as an organizing structure for future growth.

Xiaguan Analysis
1.1
SITE The Xiaguan site is a rich mixture of historic structures and uses, active and defunct infrastructure, and hidden natural elements and amenities. The site is approximately 2 kilometers north to south and 1 kilometer wide with an area of approximately 150 hectares (1.5 square kilometers).
2.0
km
Though few and concealed, the site has several interesting natural features. Several large ponds and canals are scattered through the site. These water features have potential as recreational amenities, but currently are inaccessible and heavily polluted. The Yangtze River is a spectacular natural amenity but is separated from the city by a large flood wall and industrial uses. The city moat near the Lion Mountain is a hard, un-crossable edge. The green elements to the site are primarily made up of beautiful tree lined roads that could be preserved and enhanced. The Lion Mountain constitutes the sites most prominent open space feature just outside the site, though access is limited from the site.
km
Important landmarks include a highly-visible smoke stack in the southern portion of the site. This element creates a view corridor linking to the Lion Mountain Tower, the most visible landmark on the site. Views to the tower can provide important organizing forces to the site’s design. The river and the Bridge are other important landmarks that deserve greater attention and preserved views. Rail lines bisect the site in many places creating both problems for an integrated design solution as well as potential catalysts for the design process. The large turn-around in the north part of the site, in particular, presents and interesting site element. The road network consists of two large arterials in the southern portion of the site and larger route forming the eastern and southern edge of the site. Internally, the road network is ill-defined and disconnected. Connectivity through the site will be important for future development.

SCALE COMPARISON The 1.5 Square Kilometer site is large and complex. Comparison to areas within several American cities provides insight into the range and scale of development possible within its borders. The site is large enough to house the downtown of many American cities (such as Baltimore) or a gradient of urban fabric (such as in Denver or Philadelphia). Comparison to New York city shows the density potential of the site given the scale of New York development. Though reusing American ideas and form may not be appropriate for the site, though do illuminate its potential. The shear scale and diversity of uses that can fit within the site should be considered when approaching the design for the area.

SMOKESTACK AND INDUSTRY District 1 is located at the western part of the site and adjacent to the Yangtze river which makes it an important location for future waterfront developments. The existing condition of the site is very poor industrialized area with old, deteriorated residential buildings that are unlivable. District 1 has many assets for future developments since the site has poor facilities and infrastructure. There are some historic buildings in the site, which gives it a character that distinguishes it from the surroundings districts. The smokestack is the main visible symbol that enriches the identity of the site which still functions along with the power plant adjacent to it. The site has also some constraints such as the viaduct that passes at the east of it and considered an important traffic carrier in the city of Nanjing. Nevertheless, the infrastructure of the area lacks connectivity and safe pedestrian walkways especially with the existence of the viaduct that doesn’t provide a pleasant livable or walkable environment.

Xiaguan Analysis
Strengths Location of site near waterfront. Proximity to public transportation (ferry and subway stations). Identity of site tied to smokestack and power plant. Accessible from many areas of Nanjing. Accessible from regional transportation (trains station and expressway). Weaknesses
A
Lack of interior infrastructure (branch streets). No storm water system in place. Waterfront is underdeveloped for industry and livability. Little pedestrian connection to waterfront. Most structures are dilapidated.
B
Opportunities The waterfront presents a great opportunity to create main hub for business and circulation through the entire area. Ferry station can become a major transit center for the area to connect area with other side of river. The smokestack can be a symbol for the identity of the district and create a connection with Nanjing’s past. Constraints The existing expressway and arterial roads have bounded the edges of the site. Placement of the historic buildings (smokestack and school) on the site dictate placement of future development. Change of site use from industrial to commercial will have drastic affect on residents. Existing subway station anchors one side of site.
C A. Arterial streets are line with small retail and residential. Most buildings are dilapidated and are in need of repair.
D B. District one is dominated by the Xiaguan Power Plant. It is located in the venter of the district with a smokestack and four super structures.
C. There are few pre-defined streets in the district besides small pedestrian paths. Area is also primarily industrial.
D. The west side of the district is bounded by the Yangtze River where many ships are docked.

Xiaguan Analysis
District 1 has a unique location for futuristic and modern buildings that matches the other districts in the site. Since there are only few historic buildings, it offers large area for other type of developments that makes a new small scale CBD with tall buildings, contemporary architecture and workplace for residents and visitors of Nanjing. There are several important connections between the district and other districts in terms of infrastructure; the boulevard or main connection is a viable link between all districts that provides consistency and continuity of the urban fabric and buildings pattern/scale. Another connection is the waterfront, which goes along several districts and provides good opportunities for water transportation. The third connection is the view of the landmarks to the site and the character of the entire site which includes mixed-use, residential and commercial areas that all make it compact, sustainable and consistent.

Xiaguan Analysis
To fully understand the existing conditions we diagrammed the district using the Lynchian model. The primary nodes are ZongShan Pier and the subway station that is scheduled to be built. The edges are the Yangtze River to the west and the raised expressway to the east. The single prominent landmark is the Xiaguan Power Plant smokestack. The paths are Jianning Road to the north and Zhongshan Road to the south. Finally, District 1 is a district in itself that is characterized by heavy industry. We also diagrammed the walkability of the site through 400 meter bubbles radiating from the pier and the subway station. We studied the average building heights of the existing structures compared to the smokestack to understand their scales. Finally, we overlayed the existing land uses for the site.
A. Lynchian study

B. Walkability Diagram from pier and subway station
C. The building height study showed that the smokestack is visible from nearly the whole site. The only competing building is the office structure to the west of the district.
Xiaguan Analysis
A. While our best guesses were made to the land use of the district, the primary use is industry. While there are also mid-rise residential buildings, there is also a pocket if single family structures near the center of the district.
B. There is a wide range of uses of land in our district. From industry to retail to commercial to education to residential.

TRADITIONAL NEIGHBORHOOD & WATERFRONT District 2 Wws a major business, distribution, commercial, and port hub in the city of Nanjing. District 2 was once the trading center for the whole city, Dama Road in the center of the district, being the most area. Dama Road contains many historical buildings, many of which have British and western influence architecture. In the 19th Century, the area around Dama Road was considered the city center because the area contained all areas of commerce. However, after WWII, much of the area was destroyed and the city center was rebuilt elsewhere. The shipping and port industry was eventually replaced because of railway transportationmoving the city center more inland from the Yangtze River. Shops on Damalu Rd closed, and people moved out of the area because there were no jobs. District 2 has the most number of historical architectures (mainly built in R.0.C era, 1910s to 1940s), and has great sight lines of the mountain nearby as well as the beautiful Ancient building, Yuejianglou on the mountain, which is near the city moat. and has possibilities to have deeper connection with them. Within District 2, lies Tianbao Village, which means “God Blessed�. The village has over 100 years of history and is a reminder of that time in Nanjing. However, the village is the poorest and oldest in the city because it is now located on the edge of the city. There is also a Catholic Church located within the village.

WATERFRONT AND CHANNEL The Yangtze River, Huimin River, the Moat, the Ming City Wall, and Eight Mountains use to form a natural landscape that is now in detriment. The natural water system was destroyed when it became a landfill site and now the Huimin River is a source of contamination in stormwater and flood events. In the 1970s there was an onset of illegal building in the district that has increased the amount of unkempt drainage; likewise, people are washing dishes and rice in the river, contributing to polluted waters that were once clean. A. Nanjing Ferry Institution Located in the old river Estuary of number 57, and the jurisdiction of the field lines, Zhanqiao, ferries and other facilities are located in the Beijing Road of the old River Estuary in both Xiaguan District and Pukou District,built in 1933,which also the China’s first railway train ferry line. In 1968 October, the Nanjing Yangtze River Bridge opened, coach and through goods train through the bridge through. The ferry crossing only non direct cargo (military combat readiness) train, twowheeled voyage.

• •
Provide a front door for the river...not a back door. Breakdown existing barriers to river connections Paths & Greenways: connected greenway along river. Increase public access to river with overlooks and public parks. Integrate stormwater management, flood mitigation and water interaction at the rivers edge and canal. Strengthen the SOM multi-modal connections on a micro-scale. Observe various housing densities; challenging vertical building. Establish an identifiable character and recognizable style - possibly something to do with Canals? Preserve views of the pagota from the river port and the Canal Create a landmark at the riverfront that pulls people through to the river (Ferry Institution?). Develop the river as a recreational amenity, attracting tourists and enhancing Nanjing’s image as a desirable place to live, work, and visit. Use artwork, cultural institutions, parks and entertainment to create a tourist economy and celebrate Yantze’s important industrial past. Cultural development should be a revival of civilian culture. Accentuate the concentrated expression of the “combination of mountain, water, city and forest” in Nanjing.

HISTORIC STATION Site 4 is mainly characterized by railway tracks and industrial areas. The old railway station, located at the eastern edge of the site, is no longer in use and decaying. Nevertheless the historic building is a decisive landmark and has the potential to become the identity defining heart of the district. Railway tracks, lined with industrial buildings, dominate the central part of site 4. On the eastern edge the use and the building structure change significantly from industrial into residential. The site is surrounded by diverse neighborhoods: The southern edge of the site is marked by the Lulong Lake. On the other side of the lake lies the historic Yuejianglou district with the scenic Lion Rock Park including the city wall and a couple of temples. While the site itself is flat, the topographie on the southern side of the lake is steep. On top of the hill sits a pagoda that can be seen from a long distance. To the southeast of the site extends a commercial district with a shopping mall. Northwest of the site the Huiminhe River connects to the waterfront. To the North of the site large rail yards extend. Close to the site lies the Dahong Pond, that looks contaminated and is affected by its industrial surroundings.

Precedent Study_ BIKE INFRASTRUCTURE Copenhagen, Denmark Copenhagen is a model for the world when it comes to bicycle infrastructure. More people in the greater metropolitan area of Copenhagen commute to work and school each day than the entire bicycle commuting population of the United States. An estimated 36% of the city’s population makes biking a part of their daily routine, creating a healthier populous and a safer urban environment with less cars on its roads and a greater pedestrian realm. Over 1.2 million kilometers are cycled each day by locals throughout a well designed and planned system that connects and extends to the far reaches of the metro area. Despite the less than ideal weather of cold wet winters with occasional snow the streets are full of bicycle commuters due to the quality and specialized amenities of the bicycle infrastructure. Brought on by an energy crisis and oil shortage in the 1970s the government was forced to take measures to reduce the countries oil consumption and began implementing ‘Car-Free’ days in the city. The resurgence of bicycle usage prompted extensive investment in bicycle infrastructure in a city that was on its way to being taken over by the car. Those investments have made Copenhagen the ‘Most-Bicycle Friendly City’ in the world and a global consultant to other countries beginning to cope with raising prices of oil and the reality of car consumed downtowns. Nanjing, China is a rapidly growing city with great bicycle infrastructure already in place. The Xiaguan Project area needs to be developed to take advantage of this to create a healthy, sustainable lasting place.

Precedent Study_ BATTERY PARK CITY New York City, NY, USA Battery Park City, on the southern tip of Manhattan, is a master planned community built on a strict set of design guidelines. Originally conceived in the 1960s, the project only reached full build-out in the last decade. The development sits entirely on portion of the Hudson River that was reclaimed as developable land using fill from the World Trade Center project in the 1970s. Prior to development, a Battery Park City design committee was formed to act as stewards for the quality and shape of the future area. Strict development guidelines were established that dictated the form of buildings and the provision of open spaces and amenities. A master plan was created that was to shape the development around a set of principles such as view corridors, landmarks identity, open space access, and a compatible arrangement of uses. In order to ensure an equitable solution on the newly created land, developers had to agree to share revenue to a fund responsible for creating public, affordable housing elsewhere in the city. Additionally, the City of New York, directs a portion of taxes originating from the site towards these uses. Though successful as a development in terms of unit sales and rentals, some argue that the new district lacks the dynamic mix of uses and vibrancy of life that is charactersitic of the City. The case study is relevant as it is a master planned community based around a large river, similar to the conditions found on site in Xiaguan.

Precedent Study_ CHICAGO RIVER CHICAGO, ILLINOIS, USA development area: • water surface: about 5.7 ha • land: approx 15.4 ha • east-west direction: approximately 400 m • north-south direction: approximately 2,000 m land uses: • residential: 700 GR (31% of GFA) • office / retail: 51% of gross floor area • art / culture: 18% of gross floor area •
The project has created approximately 2,200 jobs within its boundaries.
•
The project is set on the actual Rheinauhafen, a formerly commercial harbour developed during the 1880’s.
•
Planning for the redevelopment project commenced with an urban design competition during the early 1990’s, with construction starting in 2002 and scheduled to be completed by 2011. The project is comprised of offices, cultural institutions, hotels and residential units. The formerly commercial port is now being used as a marina.
•
Architectural landmarks are the former Siebengebirge wharf warehouses and the three Kranhaus buildings (from south to north “KranhausPLUS”, “Kranhaus1” and “Pandion Vista”), allegorizing the historical harbour cranes. The middle one was awarded the MIPIM Award in Cannes.

Observations: 1. The site has good pedestrian, vehicular and transit connections to the surrounding city and neighborhoods 2. There is no “green” open space, but there is plentiful and well situated public plazas 3. The development of the site was done in such a way that it re-purposed several original historic buildings along with the new modern construction, the integration of new and old is noticeable yet consistent with the context of the city 4. The mix of uses, from cultural, office, retail and residential is seamless and well blended 5. The construction of the three iconic Kranhaus buildings provides a identifiable image for the development and a new landmark for the city 6. The potential elements at Rheinauhafen that could influence our Nanjing site include easy river access, identifiable character, high density mixed use, close proximity to historic city center and multiple connections and modes into and through the site. Nanjing possibilities: • capitalize on what makes our site unique - the canals • high density doesn’t have to mean - high rise • green space is good, but the entire river front doesn’t need to be a “park” • the inclusion of cultural and institutional uses within the development • a tourism destination Nanjing limitations: • existing water, sewer and power infrastructure • access into and through the site is limited • the degraded riverfront and canal system

Paths & Greenways: connected greenway along river. Public Access: increase public access to river with overlooks and public parks Green space & Habitat: Restore and protect landscape and natural habitats along the river, particularly fish habitat. Given the river’s industrial history. Create landscaped buffers and wetlands, both to soften harsh urban edges and to support wildlife. Recreation: Develop the river as a recreational amenity, attracting tourists and enhancing Chicago’ s image as a desirable place to live, work, and visit. Economic Development: Encourage economic development compatible with the river as an environmental and recreational amenity
A
The river flows through residential neighborhoods and industrial areas. Over the last 25 years, local and federal government agencies have invested more than $4 billion in pollution control and other water quality improvements in Industrial areas. More and more Chicagoans look to it as an attractive place to work, live, and play. Renewed interest in the river is resulting in new residential and commercial uses that replace industrial plants that previously relied on the river for freight.

Nanjing Possibilities: • Existing natural features such as lakes and mountains create a diverse foundation for enhanced habitat and awareness of nature. Chicago is less fortunate in this regard. • The rich history and culture of Nanjing can create opportunities for public art displays and cultural centers for celebration and education. • Nanjing’s status as a major port city with District 3 at the core of economic activity and relations with adjacent cities and world connections can be enhanced with tourist attractions and transportation along the Yangtze River. • With a heavy industrial past in District 3, there are less historical features that would limit rebuilding and extensive re mediation, necessary for river connections, habitat creation and a total revitalization effort. Nanjing Limitations: • Unlike Chicago, Nanjing must preserve view sheds that accentuate historical and cultural features; limit the heights of buildings within district 3.
D A. Proposed high rise creates a visual connection between the city and the river front.
Lessons Learned 1. Strong local and government investment and backing 2. The River is less “park like” and reflects more of the urban fabric. 3. The goal of commercial investment supports private investment and maintenance of the river “walk” but that also tends to reflect the “office park” atmosphere. 4. Generous amounts of green space create opportunities for social interaction, connections with nature, stormwater filtration, economic development and greater aesthetic values. 5. The Navy Pier is an extension of the main land, that offers tourist attraction. 6. The confluence of Lake Michigan & the Chicago River is one piece of an extensive greenway that incorporates culture with public art displays that beg interaction and make a strong statement of uniqueness for the City. 7. The Lurie Garden, just South of the confluence create habitat and human nature interaction.

Precedent Study_ THE SQUARE MILE LONDON, UK The square mile is a 1.12 square mile area in central London, which was historically definied by a city wall. The city is known for poor air quality in this area. The 2010 Londoner Survey found that pollution for traffic was the top environmental concern for Londoners. Poor air quality can cause serious health problems and reduces the quality of life for us all As recently as the 1950s, London was infamous for its pollution. In December 1952 a dense fog covered Greater London for several days, leading to a sudden rise in mortality rates. Whilst Londoners had experienced similar periods of smog, this episode led to an estimated 3,500-4,000 more deaths than would have been expected under normal conditions.

Precedent Study_ LAKE SHORE PARK CHICAGO, ILLINOIS, USA Our first precedent study was the waterfront portion of downtown Chicago, IL. We chose to include the portion containing Lake Shore Park. This portion of Chicago contains elements that we believe will work well within the constraints of District 1. First, the connection between the high-rise buildings of Chicago and the water of the lake is spanned by an arterial road. Second, This section of downtown Chicago is characterized by the landmark building, The John Hancock Building while District 1 is landmarked by the Xiaguan Power Plant smokestack. Finally, the use of Lake Shore park to bring green open space into the city could be used on our site.
A. While dissecting the site in Chicago the is the same size as District 1, it was necessary to point out specific land marks. The John Hancock Building is a landmark for this portion of the city and draws parallels to the Xiaguan Power Plant smokestack. The location of the Broadway Playhouse and the Museum of Contemporary Art have created a cultural center within the shadow the landmark building. The collection of Lake Shore Park, the Museum of Contemporary Art and Seneca Playlot Park in a single city block placed within the city and connecting to the waterfront has created a unique and successful public space. 80

Precedent Study_ FINANCIAL DISTRICT SAN FRANCISCO, CA, USA There are a lot of similarities between San Francisco’s financial district and Nanjing’s district 1 in terms of geography, topography, waterfront and history. San Francisco is a coastal city in the USA which in this portion of it show the financial district and waterfront public space that has great suggestions for Nanjing. The high-rise buildings in the financial district are surrounding Market Street which is the major street in San Francisco that carries a variety of retails and public spaces that ends in the waterfront where the ferry shopping center is located. The consistency, continuity and mixed-use character of San Francisco supported the businesses and hotels in the financial district. There also other elements that made the area more successful and livable like the public spaces, transit stops, park, waterfront activities and piers that are multi-functional. The variety of uses, diversity of users and mixed-use developments has brought not only businesses to the district but also tourists and residents, which made the area viable and functions longer than business hours.
A. Although the grid and urban pattern, buildings orientation are different, San Francisco has a variety of buildings and Market St. Provides many connections to the park, waterfront and this connection creates public spaces and pocket parks that make the area more livable and active. 82
University of Colorado Denver
B. The origin-destination concept of San Francisco adds a lot to the continuity of the district. The park, mixed-use and shopping center are great opportunities for different users. Nanjing can revitalize district 1 by having both high-rise and variety of uses that create social, diverse business environment.

Precedent Study_ DUISBURG-NORD DUISBURG, GERMANY Duisburg-Nord was designed in 1991 by Latz + Partner (Peter Latz), with the intention that it works to heal and understand the industrial past, rather than trying to reject it. The landscape park of Duisburg-Nord is a typical precedent to discuss quality buildings and planning standards for the environmental, economic and social transformation of an old industrial region. The park covers 230 hectares. The construction period was from 1992-2002. BLAST FURNACE PARK The Piazza Metallica is the symbol of this park, a metamorphosis of the existing hard and rugged industrial structure into a public park. WATER PARK The open waste water canal of the “Old Emscher“, crossing the park from east to west, was transformed into a clear water canal with bridges and footpaths, exclusively fed by the clear rainwater. RAILWAY PARK The railway lines, still open or out of operation, are the most continuous connections in the park. They form a filigree pattern, going deep into the living and working areas of the city quarters. PLAY The whole park is a big adventure playground. Old industrial structures are transformed and adaptated to form new interpretations; fantasy allows them to be used in novel and useful ways.

Precedent Study_ BERGAMO OLD CITY LOMBARDY, ITALY The old city of Bergamo in Northern Italy is characterized through its location way above the modern, newer city. The historic city center is surrounded by a wall and the former mout is remodeled into a park. Bergamo is popular with tourists but so far a short and attractive connection for pedestrians is not existing. In 2008 the City therefore held a competition to find a solution that does not only improve the connectivity but that also is a sight in itself and attracts visitors. One of the winners was Italian architect Walter Angonese, who suggested a solution with an partly underground staircase and a large underground entrance hall. The simple materiality and the clear lines set a strong architectural statement and are easy to distinguish from the historic structures. Nevertheless the new buildings do not overpower the old city, but add to the attractiveness. The entrance hall is not only an inviting gesture, it als provides the opportnity for exhibitions and tourist information. Can Bergamo be compared to Nanjing? The site in Bergamo is a bit lower than the site in Nanjing and the creek is decisively smaller than the Lulong Lake, but the setting and the requirements are very comparable.
