How to Check if Your Property Is on Riparian Land in Kenya

Riparian land in Kenya is the strip of ground bordering a river, lake or the sea that is treated in law as a protective reserve rather than ordinary private property, even where a title deed has been issued over it. The rules sit in the Environmental Management and Co-ordination (Wetlands, River Banks, Lake Shores and Sea Shore Management) Regulations, 2009, made under the Environmental Management and Co-ordination Act, 1999. The regulations define a river bank as the rising ground from the highest normal water mark bordering a river, and a lake shore the same way for a lake, with the high water mark itself defined as the historical recorded point of the highest level of contact between the water and the shore or bank.

The 2009 regulations themselves do not spell out a fixed number of metres for this reserve. The regulations give no fixed distance in metres, so how wide the reserve is on the ground depends on the river and on how it has been demarcated. Because no single figure is fixed in one place, the only way to know the exact width that applies to a specific river stretch is to ask NEMA or the Director of Surveys directly, not to assume a standard figure.

What matters for a landowner is simpler than the exact metres: a reserve can apply whether or not a survey plan or title deed shows it. A deed plan that appears to run all the way to the water’s edge does not override the regulations.

In December 2025, Lands Cabinet Secretary Alice Wahome issued a public notice announcing the start of work to demarcate and harmonize riparian reserves along what the notice called the Nairobi Rivers Corridors. The rivers named were the Nairobi, Mathare, Ngong, Miotoni, Mokoyeti, Mbagathi, Ruaka, Gethathuru and Kibagare, together with their tributaries, running right from their sources. The notice said the exercise was being carried out pursuant to a Cabinet Memorandum of 30 April 2024, and that it involved the Directors of Physical Planning and Surveys at the State Department for Lands, together with the Water Resources Authority, the National Environment Management Authority, Nairobi City County and the Nairobi Rivers Commission.

The Ministry of Lands has since published its own notice on this work, titled the Nairobi Rivers Regeneration Project, covering the demarcation of riparian reserves, wetlands and springs. Under the December 2025 notice, landowners and occupants along the named rivers were asked to grant surveyors and other authorized officers access for inspection and demarcation, and told they may be required to produce ownership documents, including title deeds, survey plans, development approvals and riparian clearances, within 14 days of being asked.

Margaret Wanjiru, chairperson of the Nairobi Rivers Commission, has said publicly that the Special Planning Area declaration behind this exercise does not by itself authorize evictions or displacement, and that any action still needs due legal process, a resettlement plan where applicable and fair compensation. That is an important distinction for anyone near one of these rivers: being inside a demarcation exercise is not the same thing as receiving an eviction order.

Separately from the national demarcation notice, Nairobi County under Governor Johnson Sakaja has continued removing structures built on riparian land in several parts of the city. Sakaja has pointed specifically to Kirichwa Kubwa in Kilimani, where he says structures on riparian reserves are being pulled down, and to Grogan, which he has described as an area where lives have been lost to flooding on land that should never have been built on. Speaking in 2026, Sakaja said that “the work to reclaim riparian land is ongoing at high speed,” and that more structures are being identified and removed as the rains continue.

Sakaja has also acknowledged that many affected owners did not simply ignore the rules. “Many people are currently losing parts of their property after receiving approvals and building on riparian land and floodplains,” he said, adding that planners and surveyors are expected to follow development regulations “whether this happened years ago or recently.” That admission matters, because it means a county approval or an architect’s sign off at the time you built is not a guarantee that the structure sits outside the reserve today, especially as river channels shift and older survey data gets revisited.

For Korogocho specifically, Sakaja has said that as of the latest inspection, no demolitions or survey pegging had taken place there, and that the law governing riparian corridors must be followed to save lives, with compensation applied fairly where it is due. The practical lesson is that different parts of the city are at different stages of this process, so a neighbour’s demolition notice does not automatically mean your own plot is next, and the reverse is also true.

The government’s position, as officials have stated it in the Naivasha and Nairobi cases below, is that a riparian reserve cannot be privately owned and that a title registered over one can be cancelled. Whether that holds for a particular parcel depends on its history and facts, so take advice from an advocate before relying on or contesting a title that touches a reserve. In practice this plays out in two different ways depending on how the title came about in the first place, and the government has been drawing that distinction openly rather than treating every riverside title the same way.

The clearest recent example comes from Naivasha, where the national government announced in August 2025 that it plans to revoke title deeds on land encroaching on riparian areas around Lake Naivasha, after rising lake levels flooded homes in Kihoto. Lands Cabinet Secretary Alice Wahome was direct about the distinction she was drawing: “You had a title which you went and secured through dubious means from the lake. That’s not a title deed that is supposed to exist in our books,” she said of titles she described as fraudulently or irregularly acquired on riparian land.

For owners she considered genuine victims of the rising lake rather than people who had knowingly grabbed riparian land, Wahome struck a different note, saying that “if a lake comes and takes its land, you cannot claim compensation, but for genuine victims, the government will explore interventions.” Naivasha’s Deputy County Commissioner at the time, Josiah Odongo, put the same distinction more bluntly for those in the second group: “We cannot compensate people who illegally acquired riparian areas and processed title deeds for the same. The only thing they can expect is for the government to cancel those deeds. The lake cannot be moved, it is for the people to move.”

Naivasha is not a one off. The same underlying problem, riparian land that was surveyed, titled and sold years ago without anyone properly checking the reserve boundary, exists wherever Kenya has a river, lake or coastline running through land that later got subdivided for sale. What made Naivasha visible was the flooding, which forced the government to look again at how parcels close to the lake had been titled in the first place, and the answer it found was that some of them never should have been.

At the time of the Naivasha announcement, officials said they did not yet have a count of how many families would be affected, and that the Director of Survey had been sent back to the area to work with the county on resetting the boundaries, supported by the Kenya Red Cross and the National Disaster Operations Centre. That is a useful detail in itself: even government officials sometimes only discover the true extent of a riparian reserve once they go back and resurvey it, which is exactly why a buyer cannot simply trust an old title or an existing fence line.

The same risk applies to land near rivers that have not yet made headlines. A parcel that has sat quietly for twenty years with a title deed that includes the riverbank does not become safe simply because nobody has checked it yet. It becomes exposed the moment flooding, a development project or a formal demarcation exercise, like the one now underway on Nairobi’s rivers, brings a surveyor back to that stretch of water.

Start with your deed plan, the diagram attached to your title that shows your parcel’s exact boundaries against the Registry Index Map. If a river, stream or lake edge appears on or near your boundary line, that is your first signal to look closer rather than a reason to panic. A deed plan drawn decades ago may also simply be out of date against how the watercourse runs today, since rivers shift course and lake levels rise and fall.

From there, the most reliable step is to ask the Director of Surveys, through the relevant county Lands office, or NEMA, to confirm where the riparian reserve actually falls on your specific parcel. This is a technical boundary question, not something you can settle by eye from the riverbank, which is why it needs the same office that handles deed plans and cadastral references rather than a general land search.

It is also worth engaging a licensed surveyor registered with the Land Surveyors Board to do an independent check against your title, particularly if you are buying rather than already owning the land. A surveyor can physically confirm the distance from the water’s current high water mark to your boundary, and flag early if your parcel, or part of it, falls inside the reserve regardless of what the paperwork says.

If your area is one of the nine rivers named in the December 2025 Nairobi notice, Nairobi, Mathare, Ngong, Miotoni, Mokoyeti, Mbagathi, Ruaka, Gethathuru or Kibagare, you can also expect the demarcation team to reach you directly in time, since that exercise is meant to cover the full length of each river from its source.

If you receive a request for documents under the current demarcation exercise, the December 2025 notice gives you 14 days to produce them, so treat that window seriously rather than assuming it will be extended. Gather your original title deed, survey plan, any development approval you hold for structures on the land, and any riparian clearance you were issued, and keep copies before handing over originals.

Cooperate with access requests for inspection and survey work. The notice frames this as part of the demarcation process itself, and resisting access is more likely to delay a resolution in your favour than to protect you, since the government is carrying out the survey regardless.

Ask, in writing, what category the exercise has placed your parcel in once a decision is reached, genuine ownership outside the reserve, encroachment to be regularised, or land to be reclaimed, since those three outcomes carry very different next steps. The Nairobi River Commission has been reported as saying that no eviction should happen without due legal process, a resettlement plan where one is needed and fair compensation, so if you are asked to leave without any of that having happened, that is worth raising with the commission or a lawyer before you act.

If your title turns out to have been acquired through the kind of dubious process officials have described in Naivasha, expect cancellation rather than compensation. If instead you are a genuine purchaser who bought in good faith from a seller whose title looked clean at the time, say so clearly and in writing, and ask what interventions, if any, the government is offering to people in your position, since that is the distinction officials have repeatedly said they are drawing.

Treat any plot marketed as riverside, lakefront or with a water view as needing an extra layer of checking, not an extra reason to buy quickly. Ask the seller directly whether any part of the parcel falls within a riparian reserve, and do not accept a verbal assurance in place of a surveyor’s written confirmation.

Request a current land search and compare the registered proprietor and acreage against the deed plan, the same first step recommended for any land purchase in Kenya, then go further by asking a licensed surveyor to check the specific distance from the current high water mark to the boundary you are being sold. If the seller resists this step or pushes you to pay a deposit before it is done, treat that resistance itself as a warning sign, the same way you would with any other land scam.

Where the parcel sits along one of the rivers currently under the Nairobi demarcation exercise, or near Lake Naivasha, ask specifically whether the land has already been assessed under that exercise, and request any documentation of the outcome. Buying into a parcel that is already flagged for demarcation, without knowing it, is a risk you can avoid simply by asking the right question before you sign anything.
