The sites span areas including Binh Trung, Cat Lai, Binh Quoi, An Phu Dong, Nha Be, Hiep Phuoc, Binh Khanh, Tan Uyen and Thuong Tan, with clusters in Tan Uyen and Hiep Phuoc (five each), An Phu Dong and Thuong Tan (four each), and Binh Quoi and Nha Be (three each).
The affected stretches total about 17.9 km and threaten around 555 households.
City officials have instructed investors in river embankment projects to accelerate approvals and begin construction, while areas with cleared land but no works underway must be temporarily reinforced, particularly on Thanh Da Peninsula.
Concerned agencies are required to conduct detailed surveys of terrain, geology and hydrology, and ensure construction quality and safety. Completed works must be handed over for proper operation and maintenance.
The construction department will fast-track embankment projects, inspect riverside roads for risks, and tighten oversight of waterways and riverbank corridors.
Police will step up enforcement against illegal sand mining on major rivers, including the Sai Gon, Dong Nai, Long Tau and Soai Rap, a key contributor to erosion.
Local authorities must issue warnings, install barriers, assist relocations where needed, accelerate land clearance for embankment works, and report additional at-risk sites by April 29.
Of the 43 sites, 11 lack investment approval, with authorities told to urgently assess and propose projects under the city’s 2030 erosion prevention plan.
