The Seoul city government said on the 22nd it finalized the rapid integrated planning (New Rapid Integrated Planning) for redevelopment in the area around 130 Mia-dong, Gangbuk District, the pilot site for the tiered park (three-dimensional park) introduced as the sixth regulatory repeal.
A tiered park is a system that eases the rule that, when carrying out large-scale maintenance projects, more than 5% of the site area had to be secured only as a flat park on natural ground. It recognizes parks created on artificial ground on top of buildings or structures, such as cultural facilities and parking lots, as mandatory parks to be secured.
The name at the time of introduction was "three-dimensional park," but it was changed to the tiered park, meaning a park created vertically and in multiple layers, so that citizens could understand it more easily.
In the area around 130 Mia-dong, housing sites were created by land readjustment projects in the 1960s and 1970s, severing the Opaesan green axis. With no particular improvements afterward, aging progressed, and most roads are narrow one-way streets 6–8 meters wide. Because of a height difference of up to 25 meters, east–west connections are not smooth.
This New Rapid Integrated Planning expands the Opaesan green axis, which had been cut off from the urban area by past housing-complex-centered development, to the area around Mia Station, and, through the introduction of the tiered park and application of a business feasibility adjustment factor, creates a residential complex of a total of 1,730 households with up to 35 stories.
To that end, the Seoul city government plans to widen parks, which are concentrated on the slopes of Opaesan and Odong Neighborhood Park, to the area around Mia Station, place community facilities under the tiered park, and create gentle pedestrian paths. It will also, in connection with the already approved Mia 9-2 district, improve the road that links east and west.
With this project, to ensure Hwagye Elementary School's sunlight is not affected, the sections adjacent to the school will be created as parks, and buildings will be designed to get taller the farther they are from the school.
Considering that national and public land accounts for as much as 25% of the entire area, the Seoul city government made it possible to expand parks and roads without separate dedications. In addition, it improved business feasibility by applying a business feasibility adjustment factor (1.8) and applying the upper limit floor area ratio for installing tiered parks.
The Seoul city government plans to push follow-up procedures, including delegated reviews by the city planning commission, with the goal of designating a maintenance zone next year.
Cho Nam-jun, head of the Urban Space Headquarters of the Seoul city government, said, "This New Rapid Integrated Planning is the first application site for the three-dimensional park (tiered park) introduced as regulatory repeal No. 6, and it is a meaningful case that found the golden ratio between 'publicness' that expands parks into citizens' daily lives and 'project feasibility' through an increase in the number of households," adding, "We will swiftly push follow-up procedures such as designating the maintenance zone to bring about tangible changes in the area that residents can feel."
