Tips
- This section provides an opportunity to describe the project in more detail than is possible from the database interrogation.
- In Section 3 the individual activities will be selected from the database as a way of highlighting the environmental changes that are likely to occur.
- See the Grey ‘Case Study’ tab for some examples
Case Study 1
Seaforth River Terminal - Mersey Estuary UK
The proposal will be carried out in two phases. Phase 1 involve the berth construction and will include the following elements:
- The construction of a new wall (approximately 750m long) between the southwest corner of Seaforth and along the low water edge of an intertidal area known as ‘Seaforth Triangle’.
- The deepening an area of the river bed in front of the proposed terminal (to -15m CD) to create a 40m wide ‘Berth Pocket’ that will allow Post Panamax vessels to berth in this area.
- The reclamation of the Seaforth Triangle area behind this new wall (using materials dredged during Berth Pocket deepening work).
Phase 2 will involve the deepening of the Outer Estuary access channel to the proposed River Terminal. Initially MDHC will operate this new terminal with the approach channel retained at its existing declared navigable depth of -6.9m CD. Within 10 years of the quay wall completion MDHC also propose to deepen shallower areas (mainly the Formby Bar and Crosby Shoal) in the Outer Estuary navigation channel to -8m CD. This is because average vessel sizes are predicted to increase with time and there will be a need to increase the length of time on each tide (the “tidal window”) that these vessels are able to access the new River Terminal. It should be noted that the Approach Channel has been dredged to, and maintained at, -8m CD in the past as this has implications for many of the interpretations in this EIA. It is expected that this capital dredging operation will take 6 to 9 months to complete.
