Authorities have issued a demolition notice targeting structures built on riparian land in Kiambiu, as part of ongoing efforts to restore waterways and reduce the risk of flooding in informal settlements.
Officials say the affected structures lie within protected zones along riverbanks, areas legally reserved to allow natural water flow and prevent encroachment.
The move follows recent heavy rains that triggered flooding across several parts of Nairobi, exposing the dangers of building on riparian reserves.
Residents have been given notice to vacate, with authorities warning that any structures within the designated buffer zones will be demolished.
The exercise is expected to be carried out by multi-agency teams, including officers from the National Environment Management Authority (NEMA) and the Nairobi City County Government.
Riparian land, typically defined as land adjacent to rivers and streams, is protected under Kenyan environmental laws to safeguard ecosystems and prevent disasters such as flooding. Encroachment on these areas has been cited as a major contributor to recurring flood incidents in densely populated settlements.
The situation in Kiambiu reflects a broader pattern seen across Nairobi, where informal developments have expanded into riverbanks and drainage corridors. In past enforcement operations, demolitions have been carried out in areas such as Kibera, Mathare and along sections of the Nairobi River, often following heavy rains or flooding incidents.
While authorities argue that the demolitions are necessary for public safety and environmental protection, the exercise is likely to raise humanitarian concerns, as many affected residents are low-income households with limited relocation options.
Urban planning experts have long warned that without proper enforcement of zoning regulations and provision of affordable housing alternatives, such demolitions risk displacing vulnerable communities without offering long-term solutions.
Officials have urged residents to comply with the notice and to seek guidance from local authorities on relocation procedures, as enforcement efforts continue to address illegal developments along Nairobi’s waterways.
