The 2026–2027 Kiambu County Annual Development Plan (ADP) marks the twelfth such plan since the inception of the devolved system of governance and the fourth under the County Integrated Development Plan (CIDP) 2023–2027. It reaffirms our unwavering commitment to the principles of devolution, bringing government closer to the people, enhancing service delivery, and fostering inclusive growth. Prepared in compliance with Section 126 of the Public Finance Management Act (PFMA), 2012, and Article 220(2) of the Constitution of Kenya, this Plan outlines our medium-term strategic priorities, key programs, and associated financing for the 2026–2027 financial year. It is aligned with Kenya’s Vision 2030, the Sustainable Development Goals (SDGs), the African Union Agenda 2063, the Bottom-Up Economic Transformation Agenda (BETA), and the Governor’s Manifesto, ensuring coherence between local aspirations and national as well as global development agendas. Drawn directly from the CIDP 2023–2027, the ADP provides a one-year implementation roadmap with well-defined objectives, costed programs, and clear monitoring and evaluation frameworks. It is the cornerstone of our budgeting process and the operational blueprint guiding the county’s social and economic transformation. This Plan is the product of broad-based consultations and participatory planning. We commend the invaluable contributions from County Departments, development partners, private sector actors, civil society, and most importantly, the people of Kiambu, whose voices and aspirations have shaped its priorities. As a county, we remain committed to enhancing our own-source revenue through strengthened revenue administration, innovation, and ongoing structural reforms. We will continue to prioritize investments in Education, Healthcare, Infrastructure, Agriculture and Livestock, and Economic Empowerment, with a deliberate focus on shifting resources from recurrent to development expenditure. This strategic shift will accelerate sustainable, inclusive, and equitable growth across the county. We extend special appreciation to H.E. the Governor for his visionary leadership, to the dedicated team in the Budget and Economic Planning Unit for their tireless work in compiling this Plan, and to all stakeholders who contributed their expertise, time, and insights. The ADP 2026–2027 is more than just a planning document—it is a collective commitment to building a prosperous, resilient, and equitable Kiambu County.
