The program envisions a vibrant 21st Century New City in the lower reaches (the Central Business District) of the Sanli River in Jiaozhou, which is compact, diverse, sustainable, and embraces one of the city’s most important resources – water. In the northern cities, the use of water resources is particularly important, and Sanli River is no exception. According to the seasonal water features, how to achieve water preservation, storage, purification, and use for landscape design is a crucial breakthrough direction.

Current situation and problems
水资源现状 | Current situation of water situation
The river channel has a balanced width, no large open water area, lack of core interface, so it is difficult to highlight the prominent position of the city CBD in social development, making it relatively monotonous and the landscape added value not abundant enough; the problem with local river sections is that the riverbed is bare, the mud is piled up, and the garbage is blocked.

驳岸现状 | Current situation of revetment
A rubber dam has been built at the junction with the middle reaches, and both ends of the dam are reinforced concrete revetments, which is not ecological, and the rest part is earth dike with a drop height of 2-3 meters and single form. This are also contains flood discharge trench and cement culvert of the surrounding area, which are all broken and need to be rectified.

土地现状 | Current situation of land
The terrain of the base is relatively flat, easy for water layout and shaping. The base is mostly the vegetable land of original inhabitants, and most of land has long been abandoned for a long time, overgrown with weeds. The planned land fit the main planned roads in the north-south direction, with the residential and commercial development land and future CBD outside the roads. The twin relationship between the park and the development land is the focus of the design. How the recreation facilities of the park serve the people, and how the ecological matrix maximumlly nourish the development of the entire area, are all important issues to be considered.

The middle section of Sanli River serves the administrative center and opens up a new situation for the image of the new city on the occasion of the new century. The lower reaches of the Sanli River serves the business center, is more open, active and ecological, and highlights the participation of citizens, which is a complex of city, landmark, water conservation, health and sustainable development, and also a link that stitches together the ecology, economy and culture of the city. From the perspective of landscape vision, the Central Business District in Jiaozhou needs to deepen its own structure, not to refer to the row upon row buildings in “Beijing, Shanghai and Guangzhou” with the “urban disease”, but to create a place of dreams full of humanistic feelings and urban vitality in virtue of the waterfront environment.

To build a vibrant waterfront landscape space with five measures
多重手段构建“城市海绵” | To build “urban sponge” with multiple means
▼海绵城市系统示意图动图，Sponge city system gif diagram
Based on the problem that urban rainfall flood has been profoundly affecting the lives of our urban residents, the project has deeply studied the ecological concept of the sponge city and implemented this goal from multiply dimensions. The whole project will be constructed as an ecological and organic urban sponge by multiple means. Sponge City is the concept of a new urban rainfall management, which means that the city has a good “elasticity” in adapting to environmental changes and responding to natural disasters caused by rain , and also can be called “hydroelastic city”, the “Construction of Low Impact Development rain System” in international general terms. When it rains, it can absorb, store, and seep water, and when necessary, it can “release” or utilize the reserved water.

Rain garden: To comprehensively consider the design combined with the factors such as rainfall environment in Jiaozhou city and the location relationship of the lower reaches of Sanli River Park. When designing the vertical relationship of green space, it consciously combine the rhythm of the distance from the road to the water bank, and gradually lower the elevation to the water bank to build a rain garden that can reduce the rain and flood; then, to plant trees, shrubs, flowers and grass to form a small rainwater retention infiltration facility for collecting rainwater from the road, and use the filtration of soil and plants to purify the rainwater to form a low-impact rainwater development system integrating collection (including diversion), filtration, storage and release (utilization).

Plant ditch: Plant ditch is the key for the park to integrate site drainage, surface catchment, soil filtration and infiltration, and planting as a whole. It can store a part of rainwater (about 500 M3) by planting water-permeable herbs as a recessed green space, which can can slow drainage and release. In addition, when heavy rain occurs, the plant ditch can prevent rain from flooding into the rain garden and send the extra rain to the riverbed.

Permeable pavement: The park’s main roads and most of the activity sites are paved with Pamia pervious concrete. Pamia pervious concrete, as a highly permeable material, has been used in Japan for many years, with excellent water permeability, water retention performance, and the efficiency several times more than ordinary pervious materials in the market. The cushion substrate with high porosity ensures high water permeability, and the surface layer of water permeability and the cushion form a ground capable of water permeability, retention and infiltration of rainwater, with excellent stability performance. The Pamia pervious concrete area in this project is about 25,000 square meters.

In essence, it is a green welfare project for the society and should not emphasize its return on investment. However, considering the large size of the park, the heavier maintenance expenditures, and the higher quality of sustainable maintenance and conservation after the completion of the park, it is indeed necessary to consider some of the benefits and profits. According to the park’s specifications, 3% of the land can be used for the construction of park management buildings, which is a breakthrough in design. Using this 3% of the area to create a small landmark building with cultural features and service functions to introduce scarce commercial resources. For example, “Shuiwan Coffee House” in the Project No. 1 plot has successfully introduced the “Kopi Luwak” and attracted a lot of people coming after its opening due to its aesthetic building shape; its annual revenue can be beneficial to supplement the maintenance cost of the park. There is a popular small building like this is set up every 500 meters, which combines management, maintenance, public toilets and recreation functions.

“保护利用”留住城市记忆 | To retain city memory through “protection and utilization”
The hinterland of the base is originally a vegetable land for the residents of the village, and the original village committee office building is still left in the No.1 plot, but disrepair for a long time and is incompatible with the development of the city; the unique double-bar Chinese scholartree with a diameter of 60cm in the courtyard of the building has seen much changes and full of history, and residents often took the bench and chatted under the tree in the past; there are also a few well-grown metasequoias, all of these have adopted targeted protection and utilization. While getting rid of the old things and introducing new things, the park also silently retain this precious city memory.

To create a multi-compound citizen activity square through the trinity design (landscape environment phenomenon, environmental ecological greening, public behavior psychology). The entrance square of the No.1 plot has a free-style opening, which provides a public space integrating entertainment, exercise, viewing, recreation and other activities for citizens, and also improves the image of the city. In addition to the multiple activities that can be carried out on the square, the changeable set-back model vertical design also takes into account the need for retreating flood, and the specific water level elevation can be flooded; there are safety platforms and warning buoys under the water to ensure people’s safety. In addition, The design has taken advantage of the height differences out of the embankment and designed a playground which will encourage children to experience and explore.

“近水楼台”铸就生态活力水岸 | To create the ecological vitality water bank in “a favourable position”
The residences on both sides of the Sanli River echo each other. The landscape of Sanli River carries the landscape interface of the communities on both banks, the sense of far away and closing of the stratification of landscapes of set-back model and building windowsills form a beautiful picture. Unlike the rigid interface formed by rows of dense buildings on the water bank in “Beijing, Shanghai, Guangzhou and Shenzhen”, in the greening relationship of Sanli River, the distance between greening and building is consciously opened, but at the same time it does not affect the closeness of people. The landscape environment of Sanli River has strongly stimulated the development and construction of surrounding communities, and escorted the value of the land in the Sanli River Central Business District, and the rising community residents has also brought vitality to the lower reaches of the Sanli River.
Improvement of water surface pattern: To make the best use of the existing water resources to adjust the surface pattern of the whole project, and expand the water surface appropriately and dig the river bed locally, so as to improve the self-purification ability of water body. The rearrangement and control of the water front form a waterfront with a sense of rhythm.

“The flashing water is bright and dazzling, and the boundless spring is full of flowers. In the secluded valley, there are beautiful girls. Peach trees are in full bloom, swaying beside the water with the breeze.
The lush willows, the curved paths, and the soft-spoken birds are constantly appearing. As you get deeper, you will feel the truth. Explore in time, never stop, you works will be as fresh as the best of the past.”
This poem comes from the Twenty-four Poem Grades · Flashy Style. The beauty hidden in nature is inexhaustible, the design method is never single, using speculative methods to continually discover new perspectives can produce a constantly innovative poetic environment. LDG adheres to the creative concept of “Explore in time, never stop, you works will be as fresh as the best of the past” to continue to promote the landscape construction of the follow-up block of Sanli River Park in Jiaozhou, hoping to bring the beautiful scenery of poetry to the Jiaozhou, namely, opening up an urban preface for the development of Central Business District in Jiaozhou in “a beautiful environment and resource conservation”.
