For many years, Ibadan has been experiencing flooding with differing degrees of severity. On 26th August 2011, a rainfall downpour of 187.5mm occurred in about 5 hours, resulting in the overflow of the Eleyele reservoir, causing the death of more than 120 people and inflicting serious damage to property and infrastructure. Following these floods, the Executive Governor of Oyo State, his Excellency, Senator Ishaq Abiola Ajimobi, set up a task force on flood prevention and management. 
The outcome was a report containing short, medium and long term recommendations to the state government, which included the proposal to prepare three masterplans for the city:

• Ibadan City Masterplan (this project);
• Solid Waste Masterplan; and
• Drainage Masterplan.

The Ibadan City Masterplan therefore sets in motion a process to address the needs of the city today and over the period to 2036. The strategies and proposals put forward are  intended to benefit all residents and visitors in Ibadan.
