the end of the air strip where it protrudes into the Lagoon; Lagoon Road to the north of the air strip; adjacent to the jetty; and Ned’s Beach in front of the shed. Most of these require little to no maintenance however changes to coastal processes will require some further protection works to occur in particular at the Lagoon Road Seabee revetment wall. This is built using hexagonal precast concrete units that are placed as a revetment over gravel or rock. It is being progressively undermined at the northern end due to erosion of the beach dune and requires stabilisation and sand nourishment to prevent further undermining. Further studies into coastal processes have been completed with a Coastal Hazard Study prepared. This study has identified interim management strategies to address some identified short term risks. Following on from the Coastal Hazard Study, a Coastal Zone Management Plan for parts of the Island will be required and out of this plan additional infrastructure assets are likely to be required. The Coastal Zone Management Plan will also consider the impact of any sea level rise due to climate change as this may accelerate current problems. Future Asset Management Plans will be developed reflecting these infrastructure works. They are not included in this plan as the extent of the works is not known at this time. Asset Disposals No disposal of marine infrastructure is envisaged. Planned Expenditures The 10 year future planned Marine infrastructure expenditure is listed in detail at Appendix 2.
