Volume One 6. Natural Character [RPS] Policy 6.1.2 – The extent of the coastal environment is identified in the Marlborough Environment Plan to establish the areas of land and coastal marine area to which management may need to be applied in order to protect the natural character of the coastal environment from inappropriate subdivision, use and development. The coastal environment includes the coastal marine area, an active coastal interface area (where the sea is the dominant element and influence on landform, vegetation and perception) and a coastal significance area (which generally includes the land up to the first coastal ridge) - see Figure 6.1. This recognises the characteristics set out in Policy 1 of the NZCPS. All of the Marlborough Sounds is considered to be coastal environment, while the south coast of Marlborough is more complex due to variation in landform. Figure 6.1: Extent of the coastal environment. The landward extent of Marlborough’s coastal environment is mapped in the MEP. Establishing the extent of the coastal environment defines the areas in which activities may need to be managed in a particular way to preserve the natural character of this environment in accordance with Section 6(a) of the RMA. This will provide resource users and the community with certainty as to the spatial area to which the natural character and other provisions of the NZCPS apply. [RPS] Policy 6.1.3 – Determine the degree of natural character in both the coastal marine and coastal terrestrial components of the coastal environment by assessing: (a) the degree of human-induced modification on abiotic systems and landforms, marine and terrestrial biotic systems and experiential qualities; and (b) natural character at a range of scales. The natural character of the coastal environment can vary significantly from place to place. An evaluation of the degree of natural character in Marlborough’s coastal environment has been undertaken. This comprised an assessment of the extent of human-induced modification in the coastal marine area and on land within the coastal environment. To assist this process, Marlborough’s coastal environment was divided into nine distinct coastal marine areas and 6 – 3
