01 EXECUTIVE SUMMARY LIJIAO VILLAGE WILL ACT AS A EXAMPLE TO PROMOTE INNER-CITY CREEK RESTORATION PLAN AROUND GUANGZHOU WHICH ADDRESS THE LAND OWNERSHIP CONFLICT BETWEEN GOVERNMENT AND LOCAL VILLAGERS. GUANGZHOU GOVERNMENT AND LOCAL COMMUNITY WILL COME TOGETHER TO CREATE MITIGATION LANDSCAPE TO LIMIT STORM-WATER AS WELL AS A SELF-ORGANIZE SOCIAL COMMUNITY HELPING RENEWAL OF URBAN VILLAGE, RATHER THAN STRUGGLING TO MAKING INNER-CITY CREEK RESTORATION PROGRESS FORWARD.
EXECUTIVE SUMMARY
PURPOSE
PURPOSE OF THIS PLAN
An alternative planning approach overcome current sluggish inner-city creeks restoration.
outline the current conflict outline the importance of the urban village
Since billion dollars has been allocated to regulate the creeks environment by Guangzhou governments. Many projects remain limited effect because of ownership conflict in urban villages and short-term engineering approaches. No real changes of inner-city creeks result in public discontent.
identify flood mitigation strategy which connect with inner-city creek restoration identify social housing strategy which support innercity creek restoration plan
This plan focusing on the integration of flood mitigation landscape and public infrastructure for social inclusion, which provides long-term strategies, principles and guidelines for the design and programming of public realm to support the restoration plan of Lijiao Creek and Lijiao Community Renewal Plan.

WHAT’S THE CONFLICT
THE DIFFICULTY OF PLANNING GUANGZHOU INNER-CITY CREEK FOR RESTORATION
Guangzhou inner-city creeks are being negatively impacted by rapid urbanization. In the meantime, urban villages are facing revolution ahead and most of creeks’ network crossing urban villages. So Guangzhou government launch a restoration plan of inner-city creeks and a reform plan of urban villages for further urban development. However, there are several conflicts between the top-down planning scheme of urban villages and inner-city creeks, such as 1) spatial needs cannot meet different interests among different stakeholders.
Therefore, the various conflicts raised government’s concern and a main principle was added to administrative regulation: Urban village redevelopment plan, (including its compensation arrangements) must be endorsed by at least 80% of the indigenous villagers in the settlement (Guangzhou City Government, 2010). And in this context, only a few of urban villages could reach the standard to reform. The conflict of compensation between villagers and government has halted the redevelopment process and inner-city creeks restoration.
2) indigenous villagers extremely reluctant to redevelop due to poor transparency planning system and entire demolition suggestion. 3) disagreement of compensation schemes due to various needs between different groups of villagers.

BACKGROUND OF INCREASING FLOODING POINTS
The basic structure of Guangzhou’s territory is formed by extensive water system. The south part of city is the second largest built-up area called Haizhu, the alluvial plains of Haizhu have been deposited by the Pearl River. Riverine wetlands and low terraces forms the natural landscape, the particular landforms combined with the northern subtropical climate evidently led to being impact easily by heavy rain events. Over past 40 years, Guangzhou has witnessed massive urban development, and Guangzhou inner-city creeks are being negatively impacted by rapid urbanization, as urban runoff increased and climate change cause intensive rainfall, Guangzhou inner-creeks became notorious for flood. Even worse, inner-city creeks in Guangzhou are close to urban villages and there are no separated sewer within it. The combined sewer as a main polluted source when flood coming, which made inner-city creek directly impact public health and city image.
distribution of Guangzhou urban villages
Because severe problems occurred in inner-city creeks, from 2009 onwards, inner-city creek restoration plan has been launched. However, real change has not happened, in 2013, there were more flooding points than 2009.

RETHINK URBAN VILLAGE
SPATIAL DEVELOPMENT PATTERN OF GUANGZHOU Guangzhou expansion occurred east of the historical centre. From the 1980s onwards, urban development spreading outwards city centre, took over almost agricultural land while a great number of villages has not been demolished. After part of land had been expropriated, they even were given rights to develop adjacent lands for industrial activities. Hence, the villages have been labeled urban villages. Parts of the booming Chinese economy, urban villages host rural migrants looking for job in cities. Different from the slums of Mumbai, Rio and other places of permanent poverty, urban villages are thresholds to urban life for millions of rural migrants. They play a critical role in the urbanization process being the economy’s labor base. The floating population of city central deliver the major part of labour force to industry and service in the city.

JOB - SOCIAL HOUSING SPATIAL LINKAGE
job–housing spatial linkage before moving into social housing
job–housing spatial linkage after moving into social housing social housing built in 1986-1999 social housing built in 2000-2005 social housing built in 2006 urban villages
Over past decades, urban transport demand has increased as a consequence of increasing urban population and economic activity. Road traffic density during peak hours in majority areas of the city is so high that average speed down to as low as 6km/h. due to lack of social housing and the distribution of them are out of city centre, it is inevitable that spatial mismatch occurred when majority of migrant households moving into those social housing neighborhoods. in figure 1, because of urban village, private lease housing tenants’ average commuting distance is short. When comparing the jobs–housing distance of the households before and after moving into Tangxia and Tongde social housing neighborhoods (figure 2), it is clear that the jobs– housing distance for subsidized rental and commercial housing residents became much longer after moving into these neighborhoods. For guangzhou traffic condition, it would be only getting worse by relocating majority migrant households to the periphery of city.

UNDERSTANDING THE SITE: LIJIAO VILLAGE
Jan
Today lijiao housing more than 13 million inhabitants. Overcrowd rooms only enough for sleeping, lack of facilities and pulluted creek cause by overflows. During 2010 - 2013, there are 4 times of more than 200mm rainfall in 24 hours in Guangzhou. (Climate changed has causing extreme downpours and it occurring more often). During these floods, the flows during the peaks of the flood were over 500% higher than the creek capacities in the Lijiao Village. Also, the capacity of existing conventional mixed sewer systems (and pumping stations) has become insufficient to handle the volume of heavy rainstorms.

NOT ENOUGH INTERIOR SPACE TO LIVE
the fast increase runoff during deluge result in combined sewage overflow back to street and outfall to creek. Poor hygiene environment emerge immediately after flood
Lijiao village as a typical example represented most of Guangzhou urban villages. It is the second largest urban village in Guangzhou, the Lijiao creek only have a few water bodies survived during the landfilling operation that accompanied the modernization of lijiao.

during these floods, the flows during the peaks of the flood were over 500% higher than the creek capacities in the Lijiao Village.
LIMITATION OF PUBLIC REALM
overcrowed rooms divided by slabs, only enough for sleeping. the lack of living room could be partly substituted by the quality of public space.
lack of facilities and little to do when one day work done makes the migrant workers lifestyle unattractive.

DESIGN PRINCIPLE
KEY FLOOD MITIGATION STRATEGIES
looking back previous state of Lijiao village, there are rich water network around its territory. instead of reappearing all vanished water structure, used vanished water network as guide for new surface drainage system to connect all flood mitigation landscape which Inspired from Guangzhou vernacular sewer around old town.
VANISHED WATER-NETWORK
BEFORE
CURRENT
The vernacular drains were simply used as a discharge of residential wasted water. Although they disappeared in most of urban villages, but they can be a form of surface storm-water drainage in regarding of such building density urban village
VERNACULAR SEWER AROUND OLD TOWN
SUNKEN CIRCULATION
LOCAL DETENTION CURRENT SITUATION
PROPOSED STRATEGY
combined sewer with street storm drains and residential wasted water
local detention and slow release storm-water
water can be stored for water-scape and recycling
fast increase runoff during deluge result in combined sewage outflow into Lijiao creek
13
By analyzing current water drainage system, because of street storm drains combined with residential wasted sewer, fast increase runoff during deluge inevitably result in combined sewage outflow into Lijiao Creek. Rather than building separated sewer, introduce local detention strategy to slow release storm-water, as well as storing water for recycling usage.

Based on a long-term progress, provide recommended flood mitigation infrastructure which meet variety measurement. Applied tools in different stage, according to different aspects such as social interaction, environment benefit ,water retention capacity , feasibility and cost etc. The intervention guide tools is intended to inform the basis for preparing design for proposed public space which combined flood mitigation infrastructure. Furthermore it provide reference assessment for testing whether the water management system works during the iteration design process.
DESIGN PRINCIPLE
KEY SPATIAL STRATEGIES /use village fabric support flood mitigation landscape Because of lack of public space within village and flood mitigation landscape required enough room to apply, the spatial strategies introduce a hybrid mixused infrastructure that not only provides public space but also functions a flood mitigation landscape.
BORDER AS EXCHANGE POINT
In order to promote interaction among the territory and increase the efficiency of service provision. The idea of from Russian micro-rayon to urban village is to adjust the service provision from community centre to the borders between different communities. (figure 1-4)

MASTER PLAN VISION & STRATEGIC DIRECTIONS
WATER MANAGEMENT STRATEGY •
vanished water network as guide to reintroduce a new surface drainage system
•
create local water detention system to capture the flowing water, temporarily relieving existing storm pipes. spreading water capacity throughout the site
•
water detention system grow by time, contains current village’s legacy Instead of building centralized water infrastructure
OPEN DRAINAGE SYSTEM a series of storm-water drainage chain together sunken imperious ground.
A NETWORK OF DISCONTINUOUS AND DIVERSE PUBLIC SPACE •
well-linked and convenient location
•
include both active and passive used and activities
•
removal of existing housing will be stock on site vertically, left over room convert to public space
•
several functional public space based on the size of reclaiming block
FLOOD MITIGATION LANDSCAPES (PUBLIC SPACE) Green space serve as public spaces except in dramatic storms as they absorb water events.
SOCIAL HOUSING STRATEGY •
use of borders between communities
•
proposed drainage path as guide for reclaimed areas
•
reclaiming block convert to public space which integrate institutional facilities such as child-care center, library, youth center, etc. people are rehoused on site in vertical style building
•
local context taken into account and form of open space
PROGRAMMING IN SOCIAL HOUSING new social housing as social node by adding social service that gives character and active social life to the site.

TRANSFORMATION CONCEPT / releasing spaces
MITIGATION LANDSCAPE AND OPEN SPACES CAN BE TRANSFORMED FROM A COLLECTIVE PROPERTY OWNERSHIP LAND CONFIGURATION
There is no room in Ljiao to build a separated drainage system as well as a open space for flood mitigation. However, if part of existing individual property spaces were to be stack together, they might create a space that big enough for flood mitigation landscape. So the potential is there to transform existing space for a collective building and create a discontinuous open space based on the design principle. And those fragments hybrid infrastructure actually well located for people better use and function well to limited the impact from storm-water. the collective building include amenities, lower floors as commercial and public service that make the local community active. in order to bring diversity live style into Lijiao Village. Each transformed lot .instead of simulating one unique open space. The variety of agencies influenced the interface as demand. this process was meant to continue until the capacity of absorbing on site storm-water has been match. the design factors of Lijiao public realm have been carefully translated into simple design rules and typology matrix, which can be found in page 49-51
DESIGN CHECKLIST
A network of diverse public spaces enables a variety of experiences and uses. Public spaces in Lijiao must be complementary to the needs of the local community whilst ensuring they also support the water management system. The follow up brief highlighted the opportunity for flood mitigation initiatives and a linked approach to the public realm to be consolidated as a deliverable action plan: •
provide a range of diverse water detention landscape in public spaces to suit different uses, meet diverse local population demand.
•
provide a range of institutional facilities to ease social inequality in Lijiao community.
•
provide a range of activities and use that connect and engage with the Lijiao community.
The deliverable action plan combined 1.water management scenario 2. social housing scenario.

BENEFITS OF BUILDING PARTNERSHIP BETWEEN GOVERNMENT AND LOCAL COMMUNITY
BENEFIT ASSUMPTIONS resiliency + improvement public space, the way to eliminate the conflict
FINANCIAL BENEFITS FOR GOVERNMENT The existing approach of inner-city creek restoration is government-led planning. Government use restoration annually fund for water treatment plant, vegetation, separated sewage system, maintenance and compensation. Especially, the compensation fee of relocation of urban village is high. Furthermore, all of infrastructure are built and maintained by government. Comparing to joint partnership version between government and community, for the community-led planning approach government only need to spend 30% annually fund. And all of infrastructure are built by community and maintained by community. The maintenance also create jobs for the community.
ECOLOGICAL BENEFITS OF INNER-CITY CREEK Flood mitigation landscape protect streets and building from flooding during rain events and mitigate combined sewer overflow events which improves water quality in the Lijiao Creek. plants reduce air and surface temperature by shading the ground, buildings and people in hot summer. After overflow issues has been fixed, increased connections along the waterfront will encourage people taking care of Lijiao Creek.
SOCIAL AND EQUITY BENEFITS OF URBAN VILLAGE The new social co-housing will benefit from increasing income of rent and economic opportunity and neighborhood connectivity through new commercial activity in certain purposed ground floor spaces. Commercial area would house shared work spaces and business incubators. The new vocational training centre would connect migrant residents to employment-linked training opportunities connected with the new jobs generated through the direct investment and maintenance requirement. The specific skill set class required for jobs would created directly or indirectly by the Lijiao community. Flood mitigation landscape have significant community spaces which will be programmed by community groups to meet the needs of local residents. Also the new social co-housing proposes to expand affordable housing and offer better quality living space for migrant workers. The community values connectivity to the city and the inner-city creek. Lack of public realm, the urban villages have been isolate from its urban fabric , it also impact the water quality of inner-city creek. Given a network of user-based outdoor social space and richer bio-diversity, spatial quality performs better in these areas. Improvements includes easier access of waterfront, given identity for local community, a greater relationship built between residents and inner-city creek, residents will take good care of inner-city creek due to greater responsibility.

A VISUAL GUIDE TO GET INNER-CITY CREEK RESTORATION STARTED
A visual negotiation guidelines for government and local community have to develop to help building partnership for the alternative restoration plan.

When people see the first prosed idea about a self-built social housing building, they said we like it, but a new building is expensive, so, no, thanks. So to encourage investment by allowing increased rational FAR than previous in selected area. Based on the fact that, the increased area of building can be as extra lots(units) and commercial storeys. The extra lots can be sold to purchaser from outside of village. there are 2 potential investing types for villagers.

First is villager’s self fund, which Government offer fairly low interest loan (according to other success policy in other province, Implementation rules for Yiwu City Urban and Rural Construction of a new collective community, 2013).

GUIDELINE AND AGREEMENT

But
There is a idea to encourage investment and with minimum cost to build social housing building
The building can be upfront cost
Social housing scenario Villager
Based on the scenario, government allow villagers rehoused on site instead paying compensation for their relocation
The second is villager plus developer which the building can be built with no upfront cost. Then use the higher income return to pay off the loan and maintenance.
+
+
On the other hand the shared space maintained, operated, and programmed by Lijiao Village Collective Organization, in partnership with Guangzhou government. Government raises 98% of the infrastructure annual budget for flood mitigation landscape. Villagers achieved annually fund by testing feedback from the water system and monitoring reliability of maintenance of infrastructure.
Won't cost a penny to build a flood mitigation system, sounds good
Inner-city creek restoration scenario Based on the scenario, government raise initial fund to encourage villagers to build flood mitigation landscape system, and after that, annually fund achieve by testing feedback from the water system and monitoring reliability of maintenance of infrastructure

On the surface it would seem is setting up fund to help villa open space, and in return the flood mitigation infrastructure framework design.
Moreover, villagers take respo flood mitigation infrastructure maintenance cost and compe dramatically reduced

06 CONCLUSION
THE PROPOSED COLLABORATIVE PLANNING STRATEGY CAN BE DEPLOYED IN OTHER URBAN VILLAGES AND SPREAD THE WATERHOLDING CAPACITY THROUGHOUT THE CITY, EASING THE RUSH ON THE STORM DRAINS AND FINALLY IMPROVED THE WATER QUALITY OF INNER-CITY CREEK.
Thanks to the infrastructure improvements, reducing the amount of impervious material, the retention area will be necessary to keep the area from flooding. Combined, these measures can increase the quality of public space in urban village. Furthermore, the quality of migrant workers’ life style has been improved, this will be necessary to limit the gap between floating population and city residents by easing the social inequality among the city, and the self-renewal process of urban village helping itself to get rid of negative image for the city.

The proposed collective plan is a strategic instrument which accompanies processes, guides them but does not determine their course in advance. It combines a long-term perspective with an openness and enjoyment of the public realm which ease the storm-water overflow issue and the short-term commercial benefits could be seen to villagers which encourage them to participate. Participatory processes allow for individual actors as well as professionals such as building contractors, planning authorities,or water management experts to become initiators for change. The long-term vision remains elastic. It is conceived in several successive stages and constantly adjusted. So the collective plan could be expanded to deploy for other Guangzhou urban villages that fix the ownership conflict among inner-city creek restoration plan.
