Groundwater Separation Distances

Closed 8 Nov 2017

Opened 16 May 2016

Results expected 13 Dec 2017


This survey is intended to assess the performance of the draft Specifications for Separation Distances for Groundwater-Controlled Urban Development (Specifications).

The objective of the Specifications is to assist in achieving good urban form outcomes which optimise infrastructure performance whilst balancing the shared costs and risks of the development to home owners and the community.

The draft Specifications are being trialled for a period of 18 months so that consideration can be given to the outcomes in terms of built form and fill requirements, approval requirements, timelines, and development and maintenence costs of approved subdivisions.


Why your views matter

The outcomes of the survey and trial of the guidelines will inform the drafting of the final  document as a formal specification. It is intended the document will subsequently be integrated in the next revision of the Institute of Public Works Engineering Australiasia (IPWEA) Guidelines for Subdivision and Development for endorsement by the IPWEA and adoption by the WAPC.



What happens next

The survey responses will be used to inform the finalisation of the draft Specifications for Separation Distances for Groundwater - Controlled Urban Development.
