Jungnang Park is proposed as a new type of high-intensity urban park, where natural conditions are artificially intensified to produce an enhanced milieu capable to deliver nature to a large and dense urban population. The existing water-related infrastructure provides an optimal condition for the development of a natural reserve in the city, supported by the water-related infrastructure.

Jungnang topography is currently shaped as a flat surface of approximately 1,100Ha, characterized by its flatness and the presence of a peripheral berm which acts to prevent flooding of the site. To the north it limits with a consolidated urban fabric which will be extended to consolidate the park edge. On the West, South and East sides the flat surface of the site, sitting approximately around +10.5m above the water, is surrounded by a berm topping at +18.5m above water level which prevents the flooding of the site.

Public transport infrastructure

The site, which is bordered on the West by the Cheonggyecheong Stream and on the South and East by the Eungboggyo Stream has been long deprived of public transport, given its use as a large water-purifying facility. The closest rail stations are Yongdap. on the Line 2, and Janghanpyeong on the Line 5 of Seoul Metropolitan Underground system.

The road infrastructure is also very underdevelopped on the site, mostly limited to a peripheral road of very low capacity, running on top of the peripheral flood-protection berm. The site is adjacent to the merging of the two directions of the Dongbu Expressway to one side of the Eungboggyo Stream.

A denser peripheral infrastructure connecting the site to Seoungsu and Songjeong-Dong District have been planned and will provide better accessibility to the site in the future. However, we think that it will be necessary to expand the public transport infrastructure to optimize the use of the new Park.
