Nairobi Governor Johnson Sakaja announced that the county government has started moving households living along Naivasha Road out of areas identified as flood‑prone ahead of the expected El Niño rains.

In a statement issued on 28 September, the governor said the county has mapped high‑risk zones and is urging all relevant agencies to prioritise mitigation work in those hotspots.

Residents situated on riparian land or close to the Mathare, Ngong and Nairobi rivers are being instructed to relocate, with the aim of protecting lives as water levels rise.

While many households have already moved voluntarily, authorities will enforce relocation for those who remain in the most vulnerable locations.

The county’s evacuation effort is being carried out across all six Nairobi boroughs to enable a faster local response and to streamline rescue operations.

Governor Sakaja called for a single representative from each of the National Government Administrative Officers, National Police Service, Green Nairobi, Disaster Management teams, KURA, KeNHA, Kenya Red Cross and the Nairobi boroughs to operate under a unified command structure.

The State Department for Public Health and Professional Standards has issued food‑safety guidelines for households, food vendors and residential estates, urging early preparation to limit health hazards from flood‑contaminated water.

Officials warned that floodwaters could mix with sewage, potentially contaminating shallow wells, boreholes and piped supplies, especially in low‑lying districts.
