Dongmuncheon in Paju City is a river where flooding of houses and farmland occurred in the past due to old river facilities and embankments during heavy rainfall, leaving local residents with concerns about typhoon and flood damage.

The flood-prone area improvement project is carried out for areas urgently needing flood damage prevention by raising embankments or widening waterways for flood control purposes. The province invested a total of 32.9 billion KRW and began construction in June 2020, renovating a 3.2 km stretch of the river.

In particular, Dongmuncheon had eight bridges vulnerable to flooding due to insufficient freeboard (extra height secured to prevent flooding during floods) and span length (distance from the center of one pier to the center of the adjacent pier), such as Bangmisingyo Bridge. All were reconstructed according to the basic river plan and river facility standards.

As a result of this construction, Dongmuncheon, with a widened river width and secured flow cross-sectional area, was able to protect village residents from flood damage even during the extreme heavy rainfall on July 17 in the Beopwon area of Paju City, which recorded a daily rainfall of 385.7 mm (maximum hourly rainfall of 107 mm).

The province applied environmental vegetation blocks as a revetment method to protect the embankment, creating an eco-friendly river where plants can naturally grow while providing flood defense. Additionally, embankment roads, surrounding connecting roads, and vehicle access roads were improved to ensure residents can travel safely.

Kang Seong-seup, Director of the Gyeonggi Province Construction Bureau, said, “We will continue to actively focus on improving areas expected to suffer flood damage from typhoons and heavy rains during the summer, making every effort to protect the lives and property of our residents from heavy rainfall.”
