20 August 2015 Chapter 9 - Coastal Marine Other Legislation The Council will use its powers and functions under harbour legislation to control navigational conflicts between surface water activities. Moorings in the Mooring Management Areas at Waikawa Bay may be managed through a management plan under a bylaw promulgated under the Local Government Act 2002 as an alternative to the default resource consent process. Liaison The Council will send notice of permissions for structures to the Hydrographic Office of the Royal NZ Navy, and the Maritime Safety Authority. Monitoring The Council will monitor the effects of permitted and consented activities in the coastal marine area to: determine the effectiveness of plan policies and rules; assess compliance with consent conditions; and promote sustainable management. Rules and zoning will provide certainty with respect to what can and cannot be done in the coastal marine area. In addition, they provide the environmental certainty and control which is needed in this sensitive area. Policy 3.2.1 of the New Zealand Coastal Policy Statement requires plans to define the type of use and development that would be appropriate in the coastal environment. The policies and methods (ie, rules) provide guidance to resource users on this. Three specific sites appropriate for new salmon farms have been identified in the Coastal Marine Zone 3. 9.3 Issue Adverse effects of activities on the natural and physical resources of the coastal marine area. Given the geography of the Marlborough Sounds, the coastal marine area performs a significant role as a receiving environment. The Marlborough Sounds are large, drowned river valleys. Queen Charlotte Sound is the simpler of the two, approximately 45 km long and indented by many small bays and coves. Pelorus Sound is a complex maze of large inlets, bays, coves and islands. The drowned river valleys are only part of the catchments which extend inland as far as the Marlborough Sounds planning area. To a significant extent it is the activities taking place on the land which determine the environmental quality of the coastal marine area. The coastal marine area is effectively the end point for all activities and their effects. Rigid controls are necessary in the coastal marine area as this is the ‘environmental sink’ where the effects of all coastal and land-based activities impact. Coastal marine ecosystems depend on uncontaminated seawater, undisturbed seabed or foreshore and healthy land and freshwater ecosystems adjacent to the coast. 9 – 8A
