A plan designed by Lord Foster’s architectural firm would have led to the development of a four-runway airport on the Isle of Grain in the Thames Estuary. The Isle of Grain who holds roughly 1,731 people.

Local Factors
New habitats would be created to replace for the destruction on the protected sites. The grazing marshes and estuaries of North Kent are home to an internationally important number of birds, seals, dolphins, porpoises, water volves and rare insects. The grazing marshes, saltmarshes and mudflats have been recognised as a high level of importance as they provide a home for invertebrates that burrow below the surface, they feed on the nutrients filtered from the water or plants and algae. It also provides a breeding habitat for birds like Lapwings and the ditches are home to one of the last strongholds of the Water Volve. The destruction of these marshes, prevents breeding of new birds, no homes for invertebrates as well as no nutrients in the marshes soil. It is also can keep the Water Volve vulnerable to being an endangered species with only 875,000 remaining.

In 1855, as part of the military defences guarding the Thames, Grain Tower, a fort, was built. This fort remained until 1946 and was used in both World Wars. This fort was used to protect the mouth of the river Medway. This fort finally left army hands in the 1950’s, however in the 1960’s unfortunately the fort was demolished, leaving the underground sections. The tunnels, which led to truncated caponniers, still remain. The history of the Isle of Grain is very valuable and the planning of the airport should be considered carefully as all the historical factors are scattered all over Grain so it will be difficult to getting planning permission to build over the top of these as it may be not be very sustainable to the project and the environment.

Noise Pollution
The factor of noise will increase as the airport was being manufactured, this is because...
