Project Overview

As part of the Japan funded project “Strengthening the Social Stability and Resilience of Vulnerable Jordanian Communities and Syrian Refugees in Amman Against Flash Floods”, UN-Habitat has prepared a Flood Risk Assessment and Hazard Mapping Study for Downton Amman. The study identified short, medium and long term actions that need to be implemented to reduce the risk of flash floods in the city. Within the framework of the project UN-Habitat will be implementing a small scale sustainable drainage intervention including a bio- retention area and underground storm water tank. However, the study recognized the need to to implement a long term large infrastructure project such as attenuation ponds and diverting stormwater runoff coming from parts of west Amman away from down town area. On the other hand, the European Bank for Reconstruction and Development (EBRD) developed a Green City Action plan for Amman (GCAP), as part of the city’s involvement in the EBRD Green Cities programme. In alignment with the above findings, the GCAP stressed also the need to address flash floods issue in Amman and prioritized an action for developing water conveyance and/or storage to reduce flood risk in critical areas by 50% by 2040.

ESG Impact

Flash floods became a serious problem in Jordan due to rapid unplanned urbanization, insufficient capacity of drainage systems and climate change ramifications. In 2018, flash floods caused losses of lives and damage to private properties and urban infrastructure, particularly in Amman. The proposed project seeks to reduce flood risk on the city and is expected to have social and economic benefits, including but not limited to, improving the security and safety of vulnerable population, improving access to basic services, enhancing the public realm, providing revenue generating activities, reducing economic damages and promoting economic inclusion. The project has been identified by Greater Amman Municipality as one of the long term solutions to address flooding problem in Amman and is part of an integrated set of short, medium and long term interventions that can together control and eliminate the risk of flooding in critical areas in Amman.


The project will benefit population of Amman (Jordanians and refugees), particularly those who are vulnerable to flash floods in critical areas.

Risk mitigation and continuity

This project is in line with Jordan National Natural Disaster Risk Reduction Strategy (2019) endorsed by Government of Jordan, where flash floods were identified as the second priority with maximum hazard of all risks. It is also informed by the urgency of sustaining social stabilization in Amman”, The political will to implement the project from Amman is confirmed and the project has been listed in the Amman Green City Action Plan, prepared by EBRD and officially launched by Greater Amman Municipality in June 2021.
