The greatest potential impact of the development will be the increase level of noise associated with the possible increase in the aircraft movements and the increase in vehicular movement on the road network. The Borough of Southend-on-Sea is densely built-up and a number of residential areas are very close to the airport. The increase in the number air traffic movement will result increase the level of noise with take-off and landing of aircrafts. This increase in air traffic movement can be controlled through the appropriately worded condition on the future planning permission for the airport expansion. This should be clearly set out in the JAAP.

The expansion of the airport and the employment area is likely to increase the level traffic in and around the airport, to ensure that the potential impact is minimised, improvements to the public transport, cycling facilities and walking would be required as part of wider transport strategy. Scenario 3 has the potential to ensure that airport growth can contribute to the future management of the increased traffic. Any adverse impact of traffic increase can be mitigated against through improved public transport that will encourage modal shift way from the private car.

The expansion of the airport and the employment area is likely to some impact on the local ecology and/or the water quality. is increase is serving the airport should will need to be better managed to ensure that the. contribute to the need
