13. Use of the Coastal Environment Volume One this policy seeks to avoid this occurring. A jetty of the type described here is also difficult to share with adjoining landowners and increases the area of coastal marine area being occupied. [C] Policy 13.10.18 – In determining a new consent application for a lawfully-established existing jetty, the matters in Policies 13.2.1, 13.10.8, 13.10.12(a), 13.10.13, 13.10.14, 13.10.15(c), (e), (f), (g), (h), (i) and 13.10.16(c) will be considered. The extent to which the existing jetty is consistent with the direction in these policies and whether the effects of any inconsistencies can be avoided, remedied or mitigated will be a significant factor in determining whether anew consent is granted. The policies to be considered in a new coastal permit application for an existing jetty are limited and include consideration of matters that may be expected to change over time, therefore warranting reconsideration. Natural character, recreation, amenity values and public access are particularly important considerations. Additional policies for boatsheds and slipways [C] Policy 13.10.19 – The purpose of a boatshed shall be to house boats and boating equipment. Where a boatshed is to be located in the coastal marine area or on land immediately adjacent to the coastal marine area and its use differs from the purpose described above, the activity is inappropriate in the coastal environment and is to be avoided. A boatshed cannot be used for anything other than storing a boat or boating equipment. Given the public nature of the coastal marine area and reserve land adjacent to the foreshore, it is important a boatshed is used for the purpose for which consent was sought. Where this ceases to occur, the building should be removed. [C] Policy 13.10.20 – Where an application is made to construct a boatshed and/or slipway or to extend an existing structure, the following matters will be considered: (a) the nature of the boat and boating equipment to be stored in the boatshed, e.g. the size of the boat; (b) the materials to be used in construction (including cladding, doors and roofing) and the dimensions of the boatshed, including roof height and pitch, as well as the materials to be used in the construction of the slipway; and (c) opportunities for storing boats and boating equipment on private property and whether there are any launching facilities nearby. In addition to the general matters applying to all coastal structures in Policies 13.10.1 – 13.10.10, these additional matters for assessing boatsheds and slipways will help to determine the extent of impact on the values of the coastal environment. Through considering the existing environment and what the boatshed is to be used for, decision makers will be better able to determine if the structure is appropriate and whether there may be alternatives available. [C] Policy 13.10.21 – The installation of sanitary plumbing within or as part of the boatshed must be avoided. As the purpose of a boatshed is to house boats and boating equipment, there is no need for sanitary plumbing of any kind. There is no functional need for these facilities to be located within or as part of a boatshed. Such facilities are more appropriately located within a dwelling. 13 – 30
