DODDER FLOOD DEFENCE PROJECT
Dodder Flood Defence Project
Why it was needed:
- History of flooding: The River Dodder has a history of flooding, particularly during heavy rainfall events. This has caused significant damage to properties and infrastructure along its banks over the years.
- Increased risk due to climate change: Climate change is projected to increase the frequency and intensity of extreme weather events, further raising the risk of flooding.
- Urban development: Urban development within the Dodder catchment has reduced the natural ability of the land to absorb rainwater, leading to increased surface runoff and higher river levels during storms.
Details of the project:
- Multi-phase approach: The project is being delivered in several phases, addressing different sections of the river.
- Flood walls and embankments: Key measures include the construction of flood walls and embankments to contain flood waters.
- Improved drainage: Works to improve drainage systems help to manage surface water runoff and reduce the pressure on the river during heavy rain.
- Environmental considerations: The project also aims to enhance the natural environment along the river, incorporating features such as wetlands and natural floodplains to help manage flood risk.
Timeline and completion:
The Dodder Flood Defence Project is an ongoing initiative with several phases. Some sections have already been completed, such as the Donnybrook Greenway section which includes flood defences. Other phases are currently in progress or planned for the future. As of May 2024, Phase 3 is underway with ground investigations taking place and works expected to be carried out in late 2024.
While an exact completion date for the entire project has not been publicly announced, you can find updates on the progress of Phase 3 at:
