Option E

A secondary stopbank starting at the low terrace across Mount Thomas Road from Groyne 7 and joining the primary stopbank west of the airfield

This option would see us constructing a secondary stopbank starting at the low terrace on Mount Thomas Road and joining the primary stopbank along Priors Road, to the west of the airfield.

Option E: A secondary stopbank starting at the low terrace across Mount Thomas Road from Groyne 7 and joining the primary stopbank west of the airfield Pros

  • This is a shorter alignment
  • It reduces the impact of land use and construction impact on neighbouring properties

Cons

  • If the primary stopbank failed, there would be no additional protection between the airfield and Cones Road
  • Requires extensive upgrades to primary stopbank from airfield to Cones Road
