1553 142 LOCATION AND HISTORY Shanghai is located in Yangze River Delta right next to the mouth of Yangtze River in Sub tropical monsoon climate It is the largest city in China with a population of 16 7 million in 2005 It is a prominent economic CULTURE AND ART The art and culture in Yangtze River Delta has a long history Songjiang School and Huating School painting started in Ming Dynasty One of their most famous painters was Qichang Dong Shanghai School was an very important traditional art school during Qing Dynasty and twentieth century One of their most famous painters was Baoshi Fu Famous painter in modern time Yanshao Lu from Nanxiang in Jiading District was the southern equivalent of painter Keran Li Chinese Scholar Garden south of Yangtze River is famous for its integration of landscape painting and poem Architectural style especially the roof shape reflects the regional climate characters Landscape elements include pond bank stone bridge vegetation etc Jiading has abundant culture heritages and is considered as a renowned historic and cultural city south of Yangtze River It is rich in culture and education tradition with a lot of talented people in history and today It is the hometown of a lot of famous diplomats There are 12 none physical cultural heritages in Jiading District including Jiading bamboo engraving Malu bamboo knitting Medicine dyed Cloth Xuhang Grass Knitting Stone Bar and Stone Lock Nanxiang Xiaolong Bun Jiangqiao Lamb Tea Dance Taoism Music Jiading Xi Opera southern string the new landscape axis is to be created in the core of the New City connecting the green buffer with Yuanxiang Lake high density developments are located around the major open spaces and to the north of the site low density developments are located to the northwest of the site and around Yuanxiang Lake area civic programs are used to connect the Old Town with the New City Phase 1 development is the northern part of the new city Mixed use development is located in the east while the residential is located in the west and the periphery and the civic uses are in the middle Major green spaces include the Ziqidonglai Landscape Axis Yuanxiang Lake and the linear green spaces along the canals JIADING NEW CITY CENTER LANDSCAPE AXIS SCHEMATIC DESIGN FINAL REPORT 13 JDNC Adjacent Land Use of Jiading Central Park Existing Site Photos 72 Size of park 72 ha 2000 length 2600 m 350 width 350 m 35 35 min walk Existing Site Plan Jiading New Town Open Space System 2 3 SITE OPPORTUNITIES AND CONSTRAINTS SECTION 2 SITE CONTEXT 24 EXISTING SITE CONDITIONS Adjacent land uses include civic office residential commercial retail around the park which will help to activate the park 24 7 However Dongyun Jie encroaches into the park partially blocked the visual connection between the park and Yuanxiang Lake area Open space system follows the canal system and major roadway An open space network is envisioned in the Master Plan Existing factory buildings occupy part of the site The rest is mostly farmland There are street trees along all the existing roads Dongyun Jie and Dongyun Lake construction are finished JIADING NEW CITY CENTER LANDSCAPE AXIS SCHEMATIC DESIGN FINAL REPORT 14 JDNC 11 A5 A5 11 2 3 SITE OPPORTUNITIES AND CONSTRAINTS SECTION 2 SITE CONTEXT OPPORTUNITIES Natural setting of the wetland landscape and rich cultural history in the region give the project great potential in restoring wetland landscape on site and creating local cultural programs New road system and public transit provide easy accesses to the site Sophisticated canal and lake system have great potentials to become major site amenities and part of the ecological corridors An open space system with the landscape axis potentially connected with Yuanxiang Lake and Green Buffer was envisioned in the master plan The site is big yet at pedestrian scale Diverse uses around the site bring various user groups to the park Existing trees on site create great sceneries and large tree stock for future park uses Existing working farms provides great agricultural scenery and opportunities for publics to get educated in agriculture Some existing building on site have potential to be reused for sport or cultural programs provided that they are not contaminated or have been remediated CONSTRAINTS Park is fragmented by proposed roads and existing canals which limited its uses and potential as a ecological corridor The existing canal system on site requires a lot of bridges and limited the possibility to adjust road elevations The water quality in the canals is very low Untreated waste water and polluted surface runoff was discharged directly into the canal system Existing agricultural practice damaged natural wetland system and brings excessive nutrients to the adjacent water bodies Dongyun Jie elevated light rail line 11 and on grade expressway A5 created physical and visual barriers in connecting with adjacent open spaces F1 circuit to the west expressway A5 and light rail line 11 creates major noise impact to the site Potential contamination in the existing factory buildings and sites may require remediation before they become part of a public park JIADING NEW CITY CENTER LANDSCAPE AXIS SCHEMATIC DESIGN FINAL REPORT 15 JDNC 11 F1 SITE TRAFFIC The road system proposed in the government master plan provides the site easy vehicular connections with its surroundings two MRT stations are within walking distance from the site the Jiading New City area is bounded by express roads on 3 sides Yong Shen Road and Akesu Road are major internal arteries in the New Town Hu Yi Road goes directly into the Old Town Center Sheng Xin Road has elevated light rail line 11 A30 express way exit connects to He Zuo Road and major east west roads extend towards west to F1 circuit However the impact from the through traffic to the landscape axis is not considered carefully in the master plan The landscape axis is fragmented by roads and canals Disconnected green spaces limit the potential for a wildlife corridor Both West and East ends are lack of connection with adjacent green spaces Dongyun Jie encroaches into the park partially blocked the physical and visual connection between the park and Yuanxiang Lake area Wildlife Corridor Proposed Pedestrian Circulation Proposed Vehicular Circulation Traffic Impact Site Access 2 3 SITE TRAFFIC AND ROADWAY ADJUSTMENT SECTION 2 SITE CONTEXT ROAD ADJUSTMENT Five local streets are to be terminated at the park and all the traffic are to be directed to the artery roads to cross the park as the local streets are to provide access to land parcels not to bear the transportation capacity At places where the artery roads cross the park various strategies are applied to create a continuous large green space throughout At Wen Quan Road and Sheng Xin Road where the road elevation change is highly restricted due to the sophisticated infrastructure around overhead pedestrian bridge wildlife corridors are created to connect the Fitness Zone with Community Zone and the green buffer on the other side of A5 highway He Zuo Road Yong Sheng Road and Akesu Road are to be sunken into a tunnel where it cross the park and the South Yu Min Road is elevated into a landmark bridge where Gongjiabang Canal crosses to allow the park spaces to continue on grade The ultimate goal is to provide a holistic park experience and facilitate both pedestrian and wildlife movement inside and through the park A5 JIADING NEW CITY CENTER LANDSCAPE AXIS SCHEMATIC DESIGN

LANDSCAPE AXIS SCHEMATIC DESIGN FINAL REPORT 18 JDNC CONCEPT DANCING IN THE WOODS Dance The landscape concept for the Park is an interpretation of traditional Chinese painting calligraphy and dance Natural elements from the landscape such as the flying cloud and flowing water inspired these traditional Chinese art forms and their flowing dynamic forms also translate well into modern landscape design Paintings of the local artist Yanshao Lu has greatly inspired the design vocabulary of the park The choreography of movement as the paths interact with each other and with a variety of park elements forms the whole composition SECTION 1 OVERVIEW3 1 OVERALL DESIGN CONCEPT JIADING NEW CITY CENTER LANDSCAPE AXIS SCHEMATIC DESIGN FINAL REPORT 19 JDNC CONCEPT DANCING IN THE WOODS Woods This park takes the mission of restoring natural systems and reestablishing the wildlife habitat on site as well as creating an active place for people It will be dominated by large areas of plants including woodland tree groves specimen trees wetland and meadows 3 1 OVERALL DESIGN CONCEPT SECTION 3 DESIGN CONCEPT JIADING NEW CITY CENTER LANDSCAPE AXIS SCHEMATIC DESIGN FINAL REPORT 20 JDNC PARK USES In Shanghai the most popular public spaces are the paved space in shade Big varieties of activities happen in those spaces all day and year round This is a response to the local climate and people in living condition Shanghai is in sub tropical climate It does not snow in winter and gets very hot and humid in summer most people live in the apartment buildings and do not have private yards for outdoor activities Therefore outdoor public spaces becomes very critical to people s life They set the stage for people s social life 3 1 OVERALL DESIGN CONCEPT SECTION 3 DESIGN CONCEPT JIADING NEW CITY CENTER LANDSCAPE AXIS SCHEMATIC DESIGN FINAL REPORT 21 JDNC DESIGN EVOLUTION 3 1 OVERALL DESIGN CONCEPT SECTION 3 DESIGN CONCEPT The design exercise started with the big concept of the spatial configuration of the site then overlaying the circulation system on the top The two are interweaved together by the distinctive path system to create a variety of spaces JIADING NEW CITY CENTER LANDSCAPE AXIS SCHEMATIC DESIGN FINAL REPORT 22 JDNC 3 1 OVERALL DESIGN CONCEPT SECTION 3 DESIGN CONCEPT FINAL CONCEPT DANCING IN THE WOODS The landscape concept offers diverse spatial and temporal experiences The Dance of Sleeves is composed of paths which meander through the park connecting the surrounding neighborhoods and leading park users through diverse landscapes and programs The visitor experience changes by the tension of straight versus curved edges of the paths and the canal The landscape is undulated with soft sloping landforms and vegetation functioning as wildlife and pedestrian corridors crossing over major roadways while offering a rich visual experience where park users can experience the park from different levels Program elements are carefully integrated into the slopes and tops of these landforms The park layout is a cultivated expression of order influenced in some areas by the existing agricultural uses of the site with a more extensive passive expression to the West and an intensive programmed use to the East and with the Interpretive and Cultural Center in the heart of the site The design of the park is a conglomeration of civic social commercial cultural and recreational uses The park integrates the diverse and temporal landscape experiences with the natural setting of the site and rich cultural heritage in Jiading as if it is Dancing in the Woods through a sustainable design approach to create a signature landscape axis in the heart of Jiading New City Inspired by Yanshao Lu s painting Chinese calligraphy and dance the spatial configurations of the park embrace the variations of open and close monumental and intimate active and quiet urban and pastoral straight and curvilinear elevated and below All the spaces are linked by meandering paths leading towards surrounding neighborhoods and major landscape nodes beyond the park Undulating with soft sloping landforms and vegetation the park s topography offers rich visual experiences from different levels while functioning as wildlife and pedestrian corridors crossing over major roadways Program elements are carefully integrated into the slopes and tops of these landforms By restoring wetlands along all the water bodies and woodlands on high grounds with native vegetations the park offers great opportunities for native wildlife habitat and passive recreation Influenced by existing agricultural land uses some areas of the park also reflect a cultivated expression of order Dancing in the Woods conglomerates civic social commercial cultural and recreational functions into one central urban park JIADING NEW CITY CENTER LANDSCAPE AXIS SCHEMATIC DESIGN FINAL REPORT 23 JDNC The Dynamic Path an active path that bustles with activity and contemporary spaces while connecting major destinations around the park with scenic views along the way The Water Path waterfront promenade The Tranquil Path a serene path that undulates over the topography links the natural spaces within the park and the major landscape nodes beyond the site while offering scenic views The Tree Path linear path that incorporates existing Tianzhu Road and all es of street trees Path Experience Diagram SECTION 3 DESIGN CONCEPT3 1 OVERALL DESIGN CONCEPT JIADING NEW CITY CENTER LANDSCAPE AXIS SCHEMATIC DESIGN FINAL REPORT 24 JDNC The Dynamic Path The Tranquil Path SECTION 3 DESIGN CONCEPT THE DYNAMIC PATH The color of Dynamic Path was influenced by the official park name Purple Qi from the East in which purple represents auspiciousness and the path layout was inspired by the sleeve dance While the paving surface stays relatively flat throughout a band made of hard surfaces peels up and undulates to become benches trellis or canopy as needed Tree groves are inserted into the path at certain locations to create shaded seating areas and flexible spaces This path not only connects dynamic program areas and offers a scenic route throughout the park but is also a dynamic space itself THE TRANQUIL PATH The Tranquil Path offers a discovery experience through the site as it elegantly undulates over landforms and meanders through park spaces It provides a critical linkage between the spaces in the middle of the park It is all made of natural materials including stone gravel and river pebbles The layout was greatly inspired by Yanshao Lu s painting technique 3 1

history and agricultural heritage of the site and is redefined in its shape and edge conditions Wetlands and vegetated canal banks abut the Gongjiabang Canal on the west and east ends of the park with hard edged urban canal promenades on wetland terraces are situated in the middle next to major civic spaces A small canal promenade mixed with boardwalk follows the south side of the canal and leads through wetland areas government center lawn Dongynjie Development and turns into the Dongyun Lake promenade THE TREE PATH The tree path provides an on grade fast moving connection through the park The existing asphalt pavement is reduced to 1 3 of its current width and can be used as a linear trail by joggers and roller bladers The extra asphalt cut from the road can be broken into pieces on site and beautifully stacked to create vegetated swales along the path that will collect and infiltrate surface runoff from adjacent areas All the existing street trees will remain except where view and pedestrian corridors are desirable Dongyun Lake terminates this path in the Lake Zone with the iconic bridge at South Yumin Road in the background 3 1 OVERALL DESIGN CONCEPT JIADING NEW CITY
