Beneath the polished marketing renders and five-star branding language now circulating for “Diani Beach Residences by CityBlue,” a far less glamorous paper trail tells the real story.
It is a beachfront mega-project that appears to have entered Kenya’s regulatory system carrying one set of numbers while being sold to the international investment market under another, on a stretch of coastline that the law never intended for this kind of concrete sprawl.
Kenya Insights has reviewed the official Environmental and Social Impact Assessment (ESIA) notification letter issued by Bj’s Environmental Consulting Services & Supplies Ltd, dated June 22, 2026, alongside a formal memorandum of objection filed by the South Coast Residents Association (SCRA). Both documents were cross-checked against the project’s own international promotional rollout.
What emerges is a textbook case of a developer telling regulators one thing while telling investors another, on land that sits, by the project proponent’s own admission, on the first row from one of Africa’s most awarded beaches.
The numbers don’t add up and the developer’s own marketing proves it
The ESIA notification letter, addressed to the Assistant County Commissioner of Diani and signed by Bj’s Environmental Consulting Services, is unambiguous.
The proposed development on Land Reference No. 16289 “shall include 300 apartments featuring a combination of 1, 2 & 3 bedroom units distributed in 12 blocks of double storey.” That figure of 300 units is what was filed with the authorities legally empowered to assess the project’s environmental and social footprint.
But that is not the project Kenya’s investors and the international hospitality press were told about.
At the Future Hospitality Summit Africa in Nairobi, held barely three months earlier, CityBlue Hotels formally unveiled “Diani Residences by CityBlue,” developed through a partnership between The Diar Group and Staroot Real Estate, as a mixed-use destination on roughly five acres comprising between 400 and 500 units.
Trade publications covering the launch reported the same figures independently, describing a flagship development of 400 to 500 units tailored to meet the evolving needs of investors seeking high-quality rental properties and end users looking for permanent or vacation homes.
That is not a rounding error. It is a discrepancy of up to 200 units, roughly two-thirds more than what regulators were asked to assess.
SCRA’s memorandum highlights this issue directly, describing it as a “Misrepresentation of Project Scope.” The association argues that presenting a scaled-down version of the project to regulators and local stakeholders while marketing a substantially larger development internationally represents a serious failure of transparency within the ESIA process.
When the regulatory filing and the investor marketing materials differ this dramatically, serious questions arise over which version reflects the project’s true scope and whether decision-makers have been provided with complete information before evaluating its environmental impact.
Beach Zone 1 was designed for hotels, not residential concrete blocks
Diani is not an unregulated frontier where developers can simply build whatever the market demands.
The Diani Municipality Land Use and Zoning Plan, which has been gazetted and whose municipal board includes a representative from the South Coast Residents Association, designates Beach Zone 1, the prime first-row tourism frontage, specifically for hotels, resorts and hospitality developments.
The rationale is straightforward and widely recognised across premier beach destinations worldwide. Hospitality investments generate sustained local economic activity through direct employment, food and beverage procurement, business for tour operators and artisans, and substantial tourism revenue for county governments.
Residential apartment complexes, particularly those targeting international buyers seeking second homes or short-term rental investments, do not generate the same economic impact. They typically create fewer jobs, experience intermittent occupancy, and compete directly with the hotels that established Diani’s international reputation.
That distinction is central to concerns raised by hospitality commentator Mohammed Hersi, whose remarks have been circulated alongside the residents’ objection.
According to Hersi, Beach Zone 1 “was never intended to become a corridor of residential apartment blocks. It was envisioned as the tourism frontage of Diani, a place reserved for hotels, resorts and hospitality developments that generate employment, attract international visitors and contribute significantly to the local economy.”
He also warned that “once prime beachfront land is converted into residential apartments, reversing that decision becomes almost impossible.”
Satellite imagery of the site reinforces how literally “first row” this development is. The approximately five-hectare parcel lies directly between Bahari Dhow Beach Villas and The Oasis Beach Bar & Restaurant, only a short walk from Papaya Beach Bar. It is currently green, vegetated and undeveloped, separating the beach access road from the Indian Ocean.
It is precisely this low-density natural buffer that gives Diani its internationally recognised character. It is also the landscape that would be replaced by 12 double-storey apartment blocks.
An ecosystem that cannot absorb this level of development
SCRA’s memorandum relies on detailed environmental and infrastructure concerns rather than emotional arguments.
The association argues that covering a 5.14-hectare beachfront property with extensive concrete development would leave minimal space for indigenous coastal vegetation, destroy natural habitats and wildlife corridors, and eliminate the natural buffer that helps regulate the local microclimate while reducing erosion.
The infrastructure concerns are equally significant.
Diani currently lacks a centralised municipal sewerage network. Using the developer’s internationally advertised figure of up to 500 units, the project could introduce an estimated 1,500 to 2,000 residents and guests onto a single five-hectare site, generating hundreds of thousands of litres of wastewater each day.
Although the ESIA notification refers to a wastewater treatment plant, SCRA argues that such infrastructure presents a significant risk of seepage through the area’s porous coral rag geology, potentially contaminating the same marine environment that forms the project’s principal attraction.
The association also points to an already stressed freshwater aquifer. Increased dependence on boreholes could accelerate saltwater intrusion, permanently affecting groundwater supplies for neighbouring properties.
Additional concerns include pressure on an electricity grid already prone to fluctuations, potentially increasing reliance on diesel generators, and traffic congestion along beach access roads that were never designed to accommodate the daily movement of hundreds of additional vehicles, delivery trucks and service providers.
SCRA argues that the surrounding environment is not being protected through careful project design. Instead, the environment is being expected to accommodate the project’s scale.
Who is actually carrying out the environmental assessment?
Perhaps the memorandum’s most pointed criticism concerns the consultant responsible for preparing the ESIA.
SCRA states that Bj’s Environmental Consulting Services & Supplies Ltd has no functional public website and no readily verifiable record of managing environmental assessments for developments of comparable scale and environmental sensitivity.
The association argues that an ESIA involving a beachfront ecosystem of this magnitude requires consultants with demonstrable expertise in coastal dynamics and high-density infrastructure impact assessment.
According to SCRA, that level of experience has not been publicly demonstrated.
If the consultant responsible for certifying the project’s environmental suitability cannot establish a comparable track record, the association argues that the public participation process chaired by the Assistant County Commissioner risks becoming little more than a procedural exercise rather than a meaningful evaluation of a project capable of permanently reshaping Diani’s coastline.
The legal stakes are significant
SCRA’s memorandum extends beyond environmental concerns and frames the dispute as a legal matter.
The association cites Article 42 of the Constitution of Kenya, which guarantees every person the right to a clean and healthy environment, the Physical and Land Use Planning Act, 2019, which requires developments to conform to approved zoning plans, and the public participation requirements contained in the Environmental Management and Coordination Act (EMCA), Cap 387.
SCRA has formally asked Bj’s Environmental Consulting Services, Kayali Development Limited, NEMA’s Kwale County office, the Kwale County Executive Committee Member responsible for Environment, and the Diani Municipality Board to suspend the ESIA process until the project’s full scope is disclosed.
The association is also demanding verifiable evidence of the consultant’s licensing and technical capacity, together with a substantial reduction in the project’s scale to align with the area’s low-density zoning.
SCRA says it is prepared to pursue injunctions before the National Environment Tribunal and the Environment and Land Court if those concerns are not addressed.
Why this dispute extends far beyond a single beachfront property
This is not merely a local planning dispute.
It is a test case that could shape the future of every remaining undeveloped first-row beachfront parcel along Kenya’s South Coast, particularly after the completion of the Dongo Kundu Southern Bypass significantly reduced travel times from Mombasa’s international airport and increased investor interest in Diani.
If a project submitted to regulators as a 300-unit development but marketed internationally as containing up to 500 units is ultimately approved within Beach Zone 1, critics argue it could establish a precedent for similar developments throughout the coastline.
Other tourism destinations that followed this path, including parts of the Mediterranean and sections of the Indian Ocean coastline elsewhere in Africa, struggled to recover their low-density character once large-scale beachfront construction accelerated.
SCRA’s memorandum argues that comparable high-density coastal developments have historically resulted in environmental degradation, declining property values and the loss of premium international tourism markets.
The public stakeholder meeting on the project was scheduled to be chaired by the Assistant County Commissioner in Diani.
The decisions taken during that process, together with the actions of NEMA, Kwale County’s environmental leadership and the Diani Municipality Board, will determine whether Diani Beach retains the low-density tourism character that established its international reputation or follows a path of intensified coastal development.
Satellite imagery reviewed for this investigation shows the land remains green and undeveloped.
Whether it stays that way now depends less on the availability of evidence than on the willingness of institutions to enforce the planning and environmental protections already established in law.
Kenya Insights will continue to monitor the ESIA process, NEMA’s response, and any further disclosures from Kayali Development Limited, The Diar Group, Staroot Real Estate and CityBlue Hotels as the story develops.
