Geotechnical Reports: are reports relating to the structure and nature of the rocks and soil beneath a parcel of land. When are Geotechnical reports required?

A Geotechnical report can be required for all subdivisions with the exception of boundary adjustments which do not create a site intended for development. This requirement may be modified when Council receives regional Geotechnical information.

Who can prepare Geotechnical reports?

The report is to be prepared by a suitably qualified engineering geologist or professional Geotechnical Person. That is, a person who has recognised qualifications and experience in the Geotechnical field and has specific expertise in landslip risk assessment and quantification.

What is to be covered by a Geotechnical report?

The report is to include information about the site and the surrounding area which includes:

geology;
geomorphology and slope conditions:
geological history of the site relative to landslip;
surface drainage sub-surface and groundwater conditions,
soil/bedrock conditions.
soil classification relative to AS2870;
changes to natural surfaces, and;
distribution of vegetation.

it is also expected that the report will contain an explanation of the research undertaken including details of the published geological reports and maps which have been examined and an explanation of the findings.

Finally, it is essential that the report quantifies the level of risk and refers to the specific proposal under consideration Statements are to be made about the degree of risk which may result from the possible development and/uses which could be approved on each of the proposed lots. Where risk reduction measures are suggested these are to be written in a manner which can be translated into conditions of approval.

Independent Review

If the conclusions or recommendations of a report are complex or unclear, Council may require a review of the report by an independent engineering geologist or Geotechnical Engineer.

Who Assesses On-site Effluent Disposal Capability of Lots in Unsewered Area?

Council's Environmental Health Program carries out assessment of proposed lots in unsewered areas to determine their ability to dispose of effluent within lot boundaries.

SIMPLY:

Council has the power to ask for a report when any development application is lodged. glenorchy City Council always ask for a report. They can be expensive but usually represent a clarification for Council and an easier path through the approval process.
