This update report provides a summary of developments since 2011 in the airport's approach to climate change adaptation and measures taken into operations and longer term planning. This includes insights from its experience with adaptation to date as well as the implementation status of the adaptation action plan set out in the 2011 report, and new measures introduced since the 2011 report.
The new actions taken since 2011 include the following (p. 14-16):
- The Gatwick Stream Flood Alleviation Scheme was completed and in full use by August 2014.
- The airport is working with the Environment Agency to devise relevant additional flood alleviation schemes.
- It also uses the Upper Mole flood risk modelling work to test a range of development and catchment change scenarios to assess the impact on areas both up and downstream of the Airport.
- The resilience of the two North Terminal Switch Rooms has been improved by flood proofing, and upgraded back indication and pump monitoring on both the power and the pump systems.
- During 2014, resilience and relocation works were undertaken to all critical areas below the modelled datum.
- Building standards have also been implemented to prevent any further building below the datum for a 1:100 year flood event plus allowance for climate change.
