Flood planning in NSW
In NSW, flood planning is governed by the NSW Flood-Prone Land Policy and individual Council flood studies and development control plans. Many Sydney Councils require a flood report or flood risk assessment to accompany a DA for properties within a flood planning area.
CATES is familiar with flood planning requirements across a wide range of Sydney and NSW Councils, including waterfront and low-lying properties where flood risk is a key consideration in the development assessment process.
