Map of the risk of Acid Sulfate Soil (ASS) materials being disturbed by land development activities based on the likelihood of ASS materials occurring within soil profiles. This map was developed to assist planners in assessing whether development applications require additional conditions for sites where there is a risk of disturbing ASS. For further information phone the Contaminated Sites hotline 1300 762 982. This dataset was formerly known as Acid Sulphate Soil Risk Map, Albany-Torbay (DER-004). This dataset is no longer actively maintained by DWER.

Predicted risk of Acid Sulfate Soil (ASS) materials occurring within shallow soil layers in WA Estuaries (not covered by other Department of Environment ASS risk datasets) that could be disturbed by normal land development activities (drainage, excavations, dewatering). This map was developed to assist planners in assessing whether development applications require additional conditions for developments of sites where there is a risk disturbing or draining ASS/PASS. No distinction is made between potential and actual sites since the risk for further environmental degradation from disturbance or drainage is similar.

This dataset is no longer actively maintained by DWER.

Data of the risk of Potential Acid Sulfate Soil (PASS) materials being disturbed by land development activities based on the likelihood of PASS materials occurring within 3m of the ground surface for the Lower South West Region. This data is designed for use by planners to assess whether development applications for specific sites require additional conditions on the basis of whether normal land development activities carry a risk of disturbing PASS materials. Disturbance risk is rated on the basis of the likelihood of PASS materials being encountered within 3m of the ground surface should this depth of soil be disturbed in any way. The depth of 3m is considered since this was regarded as the depth that most soil disturbance activities would extend during in most land development processes. Disturbance activities in this context include drainage, excavations and dewatering. For further information phone the Contaminated Sites hotline 1300 762 982. This dataset was formerly known as Acid Sulfate Soil Risk Map, Lower South West (DER-010). This dataset is no longer actively maintained by DWER.

Points of Erosion as found in the river foreshore assessment. DISCLAIMER: While the dataset has been prepared by the Department of Water and Environmental Regulation, it contains information from State and federally funded foreshore assessment projects conducted at different times by Natural Resource Management groups with support from DWER regional offices. It should be noted that for any given location, the data provides a ‘snapshot’ of the attributes recorded at one specific time. Any information or representation expressed or implied in this database is made in good faith and on the basis that the Department of Water and Environmental Regulation and its employees are not liable for any damage or loss whatsoever which may occur as a result of action taken or not taken, as the case may be in respect of any information or representation referred to herein. Professional advice should be obtained to verify the information contained in this database before applying to particular circumstances. The Department of Water and Environmental Regulation accepts no responsibility for collecting or updating this data but some known errors are being addressed. This dataset was formerly known as Foreshore Conditions - Erosion (DOW-045)

Environmentally Sensitive Areas as declared in Environmental Protection (Environmentally Sensitive Areas) Notice 2005, Government Gazette No. 55. This dataset is provided to assist landowners and managers in determining the location of environmentally sensitive areas under the Environmental Protection Act 1986. It is not a substitute for any requirement of the legislation. Those seeking further information should contact the data custodian. The ESA data was originally produced by Department of Water (D0W), completed at 30/05/2005. Department of Environment and Conservation (DEC) produced a new ESA data set to amend errors in the ESA data set. The custodian of the Environmentally Sensitive Areas dataset is now the Department of Water and Environmental Regulation. For further information contact Clearing Regulation Branch (08) 9333 7510. This dataset was formerly known as Clearing Regulations - Environmentally Sensitive Areas (DER-016)
