Hi all, I was looking at a contract of sale and under Planning Certificate section there is a mention that the land has been classified Class 5 on the Acid Sulfate Soils Map. This is classified by the council but not any other authority. Here is an extract of planning certificate imgur.com From my understanding Class 5 is the less affected class as acid sulfate soils are not typically found in class 5 areas. Any issues/considerations in regards to buying a property in Class 5? Thanks.
