13. Use of the Coastal Environment Volume One Additional policies for jetties [C] Policy 13.10.11 – Where an application is made to construct a new jetty or to alter or extend an existing jetty, the following matters will be considered: (a) the necessity for the jetty (or alteration or extension), including whether it will be used for individual or community use or a commercial activity on land; (b) the nature of the existing environment, including: (i) the seabed profile at the proposed jetty site (to help determine the appropriate length of the jetty); (ii) the topography between the proposed site and adjacent properties; (iii) whether there are formed tracks from the proposed site to adjacent properties or whether there will be a need to construct access tracking; (iv) whether there is an existing jetty in the vicinity of the proposed site that could provide access; and (c) the extent to which the application site needs to be dredged to provide adequate depth for berthing boats and if dredging may be required in the future. In addition to the general matters applying to all coastal structures in Policies 13.10.1 – 13.10.10, these additional matters for assessing jetties will help to determine the extent of impact on the values of the coastal environment. Through considering the existing environment and the purpose of the jetty, decision makers will be better able to determine if the structure is appropriate and whether there may be alternatives available. [C] Policy 13.10.12 – Avoid the cumulative effects of jetties on the values of the coastal environment by: (a) giving priority to the sharing of jetties or the development of community jetties; and (b) considering whether there is practical road access to an application site, practical access to another jetty and/or access to existing public launching facilities in the vicinity. This policy addresses the cumulative effects of jetties along the coastal marine area. Opportunities exist for landowners to share jetties, either in terms of a new jetty being proposed or an existing jetty that may be nearby. The practicality of using an existing jetty should be considered through the application process. In determining whether practical road access is available, it is acknowledged that there is no road access to many parts of the Marlborough Sounds. Additionally, even when road access is available it may be impractical to use if there are significant distances to travel. [C] Policy 13.10.13 – The primary use of jetties by boats shall be for embarkation and disembarkation purposes, not for providing berthage for vessels for extended periods of time. The coastal marine area is available for all to use and the Marine and Coastal Area (Takutai Moana) Act 2011 provides guaranteed rights for this use. When considering this and other NZCPS and MEP policies in regard to the efficient use of occupied space in the coastal marine area, it is important that berthing of boats for long periods of time does not prevent others from using a jetty. 13 – 28
