Building surveyors must consult with Melbourne Water prior to issuing a building permit. This is to ensure that the proposed development design has considered the impacts of flooding and assets such as waterways or drains.

​A building permit application is referred if the proposed site is land liable to flooding and the land abuts a waterway or is within 20 metres of an asset or waterway (Regulation 154).

Council or building surveyors are required to consult with us to obtain flood level information. This information will assist in the setting of floor levels to protect against flooding (Regulation 153).
