excellent well researched,
although!!
This permission was granted, using the buildings and concrete area, from the old bond termonal and pad, so no redevelopement required as per new build but just replacing old for new.
this incorporated the existing atc tower in the building, and rebuilding where the old hangar used to be with a semi permanent building.
And therefore gained permission fairly simply, although two councils had to give approval as the boundary between great yarmouth and caister parish, is three quarters the way along the carpark.
Rain water run off is achieved by a bank of around 2 degrees on the runway, and outfall would go to surrounding dykes system and not therefore an issue over the relatively small area the runway would cover, the already sodden land drains there now (below sea level remember)
