Guwahati: Assam Chief Minister Himanta Biswa Sarma on Sunday, November 15, outlined the key objectives of the proposed Assam Flood Plain Zoning Bill, 2026, describing it as an initiative to introduce scientific mapping and a structured approach to flood management in the state.
In a post on X, Sarma said the proposed legislation would facilitate scientific mapping of the Brahmaputra and Barak river basins and identify clearly demarcated flood zones. The framework is intended to protect vulnerable communities while guiding safer and more informed development.
The Chief Minister said the proposed legislation would move flood management beyond conventional riverbank protection measures towards a comprehensive, basin-level planning system.
LiDAR and satellite mapping to identify flood-prone areas
The bill envisages the use of Light Detection and Ranging (LiDAR) technology and satellite-based mapping to identify areas vulnerable to flooding and regulate development based on assessed risks.
Under the proposed framework, land would be classified into three categories: prohibited, regulated and unregulated zones.
River channels and active flow areas would be designated as prohibited zones. Construction in regulated zones would be subject to specific requirements, including elevated plinths and flood-resilient building practices. Areas outside the identified flood lines would be classified as unregulated zones, where normal development could be undertaken.
Safeguards for existing property owners
The proposed legislation also includes provisions to protect the interests of existing property owners. These safeguards include protection for lawful properties and a mandatory 60-day period for public hearings and submission of objections.
The framework would also provide both online and physical mechanisms for filing appeals, according to the Chief Minister.
Funding through external assistance and grants
Sarma said the initiative would be financed through externally aided projects and grants, with the aim of avoiding any additional financial burden on the state government.
He added that the proposed framework was expected to help secure central approvals and funding support from the Ministry of Jal Shakti.
The legislation seeks to integrate flood-risk assessment into land-use planning across Assam, with the broader objective of reducing the impact of recurring floods through scientific zoning and regulated development.
