The area around 201, Sangdo-dong, Dongjak-gu, Seoul, where an aging low-rise residential neighborhood has frequently suffered damage from retaining wall collapses and flooding, will be transformed into an apartment complex with 1,800 households through the Seoul Metropolitan Government's Rapid Integrated Planning initiative.

The Seoul Metropolitan Government announced on October 21 that it had finalized the Rapid Integrated Planning proposal for the housing redevelopment project in the area around 201, Sangdo-dong. The area has been part of an urban regeneration project since 2015, but steep slopes along sections with retaining walls, narrow roads, and valley-shaped terrain have limited efforts to improve its aging residential environment.

The Seoul Metropolitan Government plans to develop the area into a residential complex with buildings of up to 35 stories and approximately 1,800 households through Rapid Integrated Planning. The project area is close to educational facilities, including Sangdo Elementary School and Sangdo Kindergarten, as well as everyday amenities such as parks and markets. Other projects are also underway in the Sangdo area, including Rapid Integrated Planning initiatives, long-term lease housing near stations, and local housing association projects.

The Seoul Metropolitan Government plans to create a park on the northern side of the project area and develop a T-shaped public cluster around it. It will connect scattered parks, public open spaces, and disconnected roads, and create community facilities for all generations. Education-focused facilities will be located near Sangdo Elementary School, while amenities such as a senior citizens' rest area will be developed in the south, where access to public transportation is convenient.

Transportation infrastructure will also be improved. With development projects totaling approximately 10,000 households planned around Seongdae-ro near the project site, the city plans to proactively respond to future transportation demand. To this end, Seongdae-ro will be widened to 17 meters and expanded to four lanes.

The area has been considered vulnerable to flooding because of its valley-shaped terrain, where rainwater collects, and aging sewer pipes buried beneath the roads. Under the Rapid Integrated Planning proposal, sewer pipes throughout the project area will be upgraded to reduce flood risk and improve traffic flow and pedestrian conditions. For the internal road running north to south, the plan is to use the surface as a road while allowing the sewer culvert below to be upgraded and maintained.

Near Sangdo Elementary School, where a retaining wall collapse occurred, buildings for community use will be placed to accommodate the changes in elevation instead of constructing a high retaining wall. This is expected to reduce the risk of collapse associated with retaining walls and make better use of the space.

"The Sangdo area will change significantly as multiple development projects move forward," said Kim Chang-gyu, head of the Seoul Metropolitan Government's Urban Space Headquarters. "With this Rapid Integrated Planning proposal laying the foundation for a residential environment that is safe from disasters, we hope the area will become a community hub where residents can gather and connect."
