Volume One 13. Use of the Coastal Environment Methods of implementation The methods listed below are to be implemented by the Council unless otherwise specified. [C, D] 13.M.24 Zoning Zones are established to provide for the operation of ports adjacent to the towns of Picton and Havelock as well as those smaller facilities located in more remote areas of Marlborough. The use of two zones reflects the different scale and type of activity/use that occurs at each facility. A Port Zone is applied to land and water areas in Picton (including Shakespeare Bay) and at Havelock, while a Port Landing Area Zone is applied to land and water areas in Elaine Bay (Tennyson Inlet) and Oyster Bay (Port Underwood). A Marina Zone is applied to land and water areas in Picton and Waikawa, while a Marina Zone has been applied to part of the land area at Havelock consistent with the activities in that particular area. [R, C, D] 13.M.25 Regional and district rules Rules provide for a range of activities within the identified zones. In many cases activities are provided for as permitted subject to standards. This reflects the operational requirements of the particular zone. The standards include bulk and location standards, standards to avoid amenity conflicts with adjoining zones and in some cases, most notably in Shakespeare Bay, a setback from boundaries to protect visual and biodiversity values. Most activities within the coastal marine area will require a resource consent, as will activities that are not related to the operational requirements of the zone. [D] 13.M.26 Liaison The Council will liaise with port and marina operators in enhancing the landscape quality and integration of foreshore areas and town centres. [C, D] 13.M.27 Guidelines for urban design The Council is developing guidelines for urban design (including for the colour of buildings) which will be applicable in the port and marina areas. Lake Grassmere Salt Works Lake Grassmere is located in southern Marlborough, approximately six kilometres south of the Awatere River and immediately north of Cape Campbell. The lake has been extensively modified for the production of solar salt. Construction of the salt works at Lake Grassmere began in 1943 in response to shortages of rubber available during World War 2. (Salt was needed to make caustic soda, which was required in the process of recycling old rubber.) The first harvest of salt occurred in 1949. Lake Grassmere was considered an ideal site for making salt for a number of reasons. Low rainfall, high sunshine hours and strong drying winds during the summer months (generally from the north-westerly direction) provided ideal environmental conditions. The lake's location was also important, situated in a large area of flat terrain with impervious soils, close to the coast and providing unimpeded access to sea water and ready access to transport facilities. Today, approximately 50 percent of New Zealand's annual salt consumption and specialist high grade salt is produced and exported from Lake Grassmere. 13 – 55
