Nairobi Governor Sakaja Johnson activated the city’s six‑borough administrative model to coordinate El Niño flood mitigation across all 85 wards.

The model consolidates the capital’s 17 sub‑counties into six zones, each overseen by a borough manager who reports directly to the governor’s office.

Multi‑agency teams have been deployed to desilt waterways, widen drainage channels and upgrade culverts as part of the pre‑emptive works.

On 7 October 2026 the governor inspected active mitigation sites, including the CBD, Country Bus area, Kayole Slaughterhouse, Kangundo Road, Matopeni Spring Valley, Garden Estate Road, Oak Place in Ridgeways and sections of Roysambu.

The boroughs are geographically defined: Central (Starehe, Kamukunji, Mathare), Western (Westlands, Dagoretti North, Dagoretti South), Northern (Kasarani, Roysambu, Ruaraka), Southern (Kibra, Lang’ata), Eastern (Embakasi North, West, Central) and South‑Eastern (Embakasi South, East, Makadara).

Governor Sakaja said the reporting chain created by the borough system gives his office a full picture of conditions across the capital by engaging just six officials rather than dozens of ward or sub‑county administrators.

He highlighted completed work along the Ngong River in Lang’ata as an example of progress under the new coordination framework.

With rains expected within days, county teams are focusing on finishing outstanding works while keeping response units ready to address any emerging incidents.

Sakaja emphasized that the borough system provides a reliable command structure through which resources can be swiftly directed to the areas most in need.
