MINISTER FOR FINANCE AND URBAN SERVICES
LEGISLATIVE ASSEMBLY QUESTION
Soil Erosion
QUESTION NO. 215
Ms Follett - asked the Minister for Finance and Urban Services
(1) What measures have been taken to prevent silt run-off from Mount Jerrabomberra affecting the Jerrabomberra Wetlands.
(2) What discussions with NSW authorities have or will
be undertaken to minimise silt entry to the ACT from
development in Queanbeyan, particularly the Jerrabomberra
Estate.
Mr Duby - the answer to the Members question is as follows:
(1) Planning for urban development on Mount Jerrabomberra is in progress. The Mount Jerrabomberra Local Environmental Study is currently open for public comment. The study includes consideration of potential soil erosion, sedimentation and land instability issues associated with urban development on the slopes of Mount Jerrabomberra. The Soil Conservation Service of NSW, the Snowy Mountains Engineering Corporation and a private engineering company have evaluated the area and submitted reports. In summary the report states that land below 20% slope is suitable for normal urban development with larger blocks being adopted for land between 20 to 27% slope. Further detailed geotechnical investigation, the preparation of a sediment and erosion control plan and an overall stormwater management program are recommendations from the study.
(2) ACT authorities are included in the public consultation process and the Interim Territory Planning Authority response on the Mount Jerrabomberra development was sent to the Queanbeyan City Council. There has been considerable discussion with NSW authorities regarding control measures to minimise the movement of silt both within NSW and into the ACT.
