The Sonepur Planning Area has been expanded to include 575 villages across 7 blocks. A master plan has been prepared for the next 20 years, aiming to accelerate residential, commercial, and industrial development in the region. With this expansion, the boundaries of the Sonepur Planning Area have been clearly defined.

The expanded area encompasses villages from Maker, Parsa, Dariyapur, Garhkha, Amaur, Sonepur, and Dighwara blocks. Sonepur Nagar Parishad and Dighwara Nagar Panchayat, along with surrounding rural areas with urban potential, are also included. According to the Urban Development and Housing Department, this master plan will also outline the development of roads, transportation, and other essential infrastructure.

The north-eastern boundary of the planning area starts from Ekderwa Masuriya and Hasanpura in Maker, passes through Baligawan and Bahloolpur Diyara in Parsa, and several villages in Dariyapur. It then covers Akilpur, Shikarpur, Semara, and Baijalpur villages in Sonepur block, reaching Sonepur Nagar Parishad.

Similarly, the west-southern boundary begins from Muroudpur and Bhuigaon in Garhkha, proceeds through Sisauni, Mahesiya, and Hariharpur in Dariyapur, and extends to Nawada, Jogini, Repura, Dumariya, and Gayaspur in Amaur. The north-western boundary stretches from Jhakhra, Amaur Aguan, Amaur Harnarayan, and Parasrampur in Amaur to Naurkarha, Hajarpur, Baikunthpur, and Kasba Maker. The south-eastern boundary starts from Sabalpur, Paheleja, Karamchak, and Lodipur in Sonepur, passing through Dudhiya, Babhangawan, Pakoliya, Ami, and Goraipur in Dighwara, finally reaching Zhaoa village.

The government asserts that this decision will transform the future of these 575 villages and make it easier for the growing population to build homes according to their needs.
