Marlborough Sounds Resource Management Plan particularly along the coastal margin, will indirectly improve the amenity found in the Sounds Residential areas. Guidelines Landscape guidelines for subdivision and residential development in the Sounds areas will be developed by the Council. These will address matters such as: • The location of buildings; • The appropriateness of a structure; • The material used and its ability to blend into the landscape; • The ability of the structure to blend into the environment; • Form and design; and • Landscaping options. Community The Council will enco urage any community initiated amenity improvement programmes to improve residential amenity standards. Plan rules set performance conditions controlling building height, potential shading of adjoining properties, and maximum building coverage. It is considered that rules are necessary because they provide maximum certainty for residents and developers of sites in residential areas where maintenance of amenities is important to people’s wellbeing and to the security of property investment. The further methods outlined above are matters which Council are either required to address or are intending to address for various reasons. They all offer progress in terms of the maintenance and enhancement of amenity values. 10.2.4 Issue The health and safety of people and communities can be adversely affected if adequate provision is not made for potable water supplies and the disposal of waste. The settlements of Picton, Waikawa and Havelock each have reticulated water supply and reticulated sewage collection and treatment systems. Residential developments outside the settlements are, in most cases, individually self-contained for water supply, sewage disposal and rubbish disposal. The Plan seeks to ensure that residential developments are served with potable water supplies, and waste treatment and disposal systems which do not contaminate the environment or compromise community health. 10.2.4.1 Objectives and Policies Objective 1 Ensure that development in residential areas does not have adverse impacts on commu nity healh stadards t n . Policy 1.1 Ensure that all proposed allotments and buildings intended for temporary or permanent human occupation make adequate provisions for: • Disposal of human sewage effluent and other wastes; and • A potable water supply. Policy 1.2 Ensure that all development in the Sounds be within the capacity of the land for on site sewage disposal if a community sewage disposal system is not available. 10 - 14
