Nairobi County began moving residents from high‑risk areas along Naivasha Road and other flood‑prone zones in anticipation of heavy El Niño rainfall.

Governor Johnson Sakaja instructed emergency agencies to focus on city flood hotspots and mandated the relocation of families living on riparian land and riverbanks to protect lives.

Sakaja noted that many households have already moved voluntarily, but those remaining in dangerous locations will be required to relocate as enforcement intensifies.

The county highlighted ongoing evacuations along the Mathare, Ngong and Nairobi rivers, citing the Naivasha Road operation as a model of coordinated action with residents.

Preparation and rescue activities will be decentralized across Nairobi’s six boroughs to enable rapid, localized response to flood emergencies.

A unified command structure will involve disaster teams, road agencies (KURA and KeNHA), law enforcement and the Kenya Red Cross, each appointing representatives to streamline operations.

County teams have already started clearing blocked waterways and drainage channels as part of flood‑mitigation efforts.

Authorities warned that floodwaters could mix with sewage, contaminating shallow wells, boreholes and piped water, especially in low‑lying areas.
