Drainage plans

Get approval for drainage plans. Get approval for on-site stormwater detention system plans.

To get approval for your drainage plans, you must complete a form and submit with your plans.
We need to ensure new developments do not damage our local stormwater drainage system, or cause an unreasonable flow of water on to downstream properties. To do this, some new developments must have on-site stormwater detention systems installed.
