Read, S.A.L.; Suggate, R.P. 1980 East Abbotsford landslide: suitability and adequacy of legislation, planning requirements, engineering and Geological Survey requirements. Lower Hutt: New Zealand Geological Survey. New Zealand Geological Survey report EG 331 28 p.
Abstract: The development of new land for subdivision is considered to involve four stages. 1) Preparation of regional schemes; 2) Preparation of district schemes; 3) Preparation of scheme plans and where necessary concept plans; 4) Construction and maintenance. The legislation considered, namely that of the Town and Country Planning Act (1977) and the Local Government Act (1974) is judged to be adequate for the provision of both planning requirements and engineering and geological survey requirements in these four stages. Improvements to practices are suggested. Regional scheme preparation requires a greater awareness and use of hazard and geological information. Distrcit scheme preparation requires adequate geotechnical surveys to ensure the suitability of land for subdivision. Scheme plan preparation requires to be associated with the adoption of codes of practice for subdivision on a New Zealand wide basis. This includes the recognition of the engineering geological contribution of these codes and implies an examination of the merits of the registration of engineering geologists. Construction and maintenance requires adequate controls including the adoption of codes of practice for construction and adequate controls on subsequent property modifications. The latter implies a need for increased public awareness of the risks involved in such modifications.
