Yes - you will need to apply for a drainage investigation and an LPD using Council's eHume Service.
No - then an LPD will be sufficient. This includes 2 dwellings only on the one titled property.
Are you changing the use of the land (ie. from residential to commercial; childcare centre; or medical centre)?

How do I submit my drainage plans and computations to Council's Civil Design department for approval?
Plans are assessed by Council's Civil Design department when a drainage investigation has been previously submitted. You can submit you application using Council's eHume Service (fees apply).
When your application has been submitted, your plans can be delivered to Council at one of our customer service centres or email them to contactus@hume.vic.gov.au - Att: Civil Design.
