Volume One 13. Use of the Coastal Environment areas and marinas to operate efficiently while also protecting amenity values for nearby residents, it will be necessary to avoid residential activities encroaching on these zones. Standards will therefore be imposed for residential activities through the use of noise contours, which reflect the present level of effect experienced by adjacent properties. [R, C, D] Policy 13.18.4 – The environmental effects from activities within Port, Port Landing Area and Marina Zones are avoided, remedied or mitigated through the setting of standards so that: (a) vehicle parking, access and loading do not adversely affect the operation of the port/marina, road system or safe pedestrian movement; (b) signage enables public identification of port and marina operations but does not dominate the landscape; (c) structures and buildings in the various Port and Marina Zones do not dominate the landscape, particularly when having regard to visual effects as viewed from the adjoining zones in Picton and Havelock; (d) the location or height of buildings does not shade sites in adjacent zones; (e) noise levels allow the zones to function effectively, but also minimise noise nuisance for surrounding residents; and (f) light spill does not occur in adjoining Urban Residential, Open Space and Business Zones. This policy seeks to manage the effects of port operations through the setting of standards for permitted activities. This will enable a wide range of activities to occur within Port Zones and Marina Zones in a manner that avoids, remedies or mitigates adverse effects of port and/or marina operations on the immediate and wider environment, including on adjoining zones. [C] Policy 13.18.5 – Dredging for the maintenance of berths and identified navigation channels shall be recognised as an appropriate activity in Port and Marina Zones subject to standards to mitigate adverse effects, including those on navigational safety, water quality and aspects of the dredging operation, such as limits on the volume able to be dredged. Although an enabling approach has been taken to dredging in and around port and marinas, limitations will be placed on the amount of material able to be dredged to ensure that navigational safety is maintained and impacts on water quality are no more than minor. [C] Policy 13.18.6 – Where dredging is proposed in Port and Marina Zones but exceeds specified volume limits or is associated with the construction of a new berth, the following matters will be considered: (a) the need for dredging, including the volume; (b) the length of time over which the dredging activity will occur; (c) how adverse effects of sediment disturbance and the release of contaminants into the surrounding environment will be mitigated; and (d) where the dredged material is to be disposed of or deposited. (Policies under Objectives 13.12a and 13.12b will also need to be considered if disposal/deposition is to occur within the coastal marine area.) Where the volume of material to be dredged exceeds that enabled through rules or where it is necessary in conjunction with the construction of a new berth, a resource consent will be required and the matters identified in this policy are to be considered through the decision making process. Additionally, the location of where the dredged spoil is to be disposed of must be identified in the 13 – 53
