+ minimise the reshaping ofthe land
+ direct stormmater to flow around the busing area and any unstable ba
+ allow room fora sediment bares, eg, sediment fence, to be located al

  

+ design the home to sult the property type, eg. construct pole homes on steep properties

 

+ avoid the permanant use of long, steep and unetable driveways

avoid the use of exposed aggregate concrate surfaces in areas where the wash-off cannot be contained
