- Announcement of the establishment plan for the natural disaster risk improvement project in Hakjang District 2 and confirmation of the topographic map
The natural disaster risk improvement project forHakjang District 2 has been announced by Sasang-gu, Busan. This project targets the area around 717-19 Hakjang-dong and covers approximately 2,800.4㎡.
The main contents of this maintenance project include the establishment of one drainage pump station (Q=1,400㎥/min) and a retention pond (V=8,800㎥). Work is scheduled to commence after the announcement of the establishment plan, and completion is planned for December 31, 2027.
Sasang-gu recognizes the area, including Hakjang District 2, as prone to frequent flooding. Therefore, this area is being promoted as part of the natural disaster risk improvement project based on the Natural Disaster Countermeasures Act. Every year, during heavy rains, flooding issues are repeatedly observed in the roads and buildings, and the vulnerability of areas including Gamjeon-dong and Hakjang-dong is consistently pointed out. Efforts are needed to improve this situation.
The current progress is at the stage of establishing the plan and confirming the topographic map. The related decisions and changes regarding the urban management plan facilities for the retention pond and roads have been officially announced, and the land and obstacles for acquisition or future use have been identified.
Construction work is slated to begin after the announcement of the establishment plan. However, various media have pointed out that delays in securing the site and administrative procedures are major causes of delays in this project. This situation has a high potential to impact future project advancement.
It is expected that the project will reduce flooding damage from heavy rains and enhance the safety of roads and underground spaces. Furthermore, it will contribute to minimizing property damage and improving the living environment for residents. In particular, installing drainage pump stations and retention ponds will allow for controlling water flow and ensuring storage capacity during rainwater inflow. Through prompt project advancement, we hope that flooding damage in the Hakjang and Gamjeon areas of Sasang-gu will no longer occur.

Frequently Asked Questions (FAQ)
Q. What does the natural disaster risk improvement project in Hakjang District 2 entail?
This project aims to reduce flood damage from heavy rains by establishing a drainage pump station and a retention pond in Hakjang District 2.
The natural disaster risk improvement project in Hakjang District 2, Busan, involves installing one drainage pump station (Q=1,400㎥/min) and a retention pond (V=8,800㎥) over an area of approximately 2,800.4㎡. The aim of this project is to enhance the safety of roads and underground spaces in this flood-prone area and to reduce damage to residents' living conditions and property. The project is set to commence after the announcement of the establishment plan and is expected to be completed by December 2027.
Q. What is the background for promoting the natural disaster risk improvement project in Hakjang District 2?
Hakjang District 2 has frequent flood damage during heavy rains, creating a need for disaster risk improvement.
The areas of Hakjang District 2 and Gamjeon-dong in Sasang-gu are recognized as habitual flooding areas, where road and underground flooding occurs repeatedly due to heavy rain every year. Therefore, a maintenance project to install drainage and retention facilities is being promoted under the Natural Disaster Countermeasures Act to improve disaster risk. The project's purpose is to alleviate the habitual flooding risks and to enhance resident safety and living conditions.
Q. What is the current status of the maintenance project in Hakjang District 2?
Currently, it is at the establishment plan and topographic map confirmation stage, with construction expected to begin.
The maintenance project in Hakjang District 2 has completed the procedures for establishing the plan and confirming the topographic map, and the decisions regarding urban management plan facilities (retention pond, roads) have been officially defined. The areas of land and obstacles for future acquisition have been identified, and construction is expected to commence after the announcement of the establishment plan. However, delays in securing the site and administrative procedures may impact project advancement.
Q. What roles do the drainage pump station and retention pond to be established in this project play?
The drainage pump station discharges water, while the retention pond stores rainwater to prevent flooding.
The drainage pump station is a facility that pumps out 1,400㎥ of water, rapidly discharging excessive rainwater. The retention pond temporarily stores around 8,800㎥ of rainwater to regulate water volume during heavy rainfall. These two facilities are crucial infrastructures that reduce flooding damage to roads and underground spaces by regulating sudden inflows of rainwater, thus decreasing regional disaster risk.
Q. When is the estimated completion date for the Hakjang District 2 maintenance project?
The project is expected to be completed by December 31, 2027.
