It's unlikely that development on all the properties identified as Flood Control Lot (FCL) are prohibited. But the proposed development may need to meet specific conditions to keep people and property safe. For instance, you might have to build on a specific area of your land, raise your building to a certain height, or avoid building where flood risk is high.

Please check the specific Hornsby Development Controls page for more details.
