Urbex Property Insights – March

You’ve found the block, picked a home design and are ready to build. But before you get caught up in the excitement of buying and building, have you thought about stormwater? As the Top End dries out from some of its wettest months on record, we catch up with Urbex General Manager Wayne Rex to discuss stormwater and what you need to consider before signing on the dotted line or pouring your first slab of concrete.

What do I need to think about before I buy?

Monsoonal downpours and heavy rainfall goes hand-in-hand with living in the tropics. While it provides a welcome relief to the steamy conditions, managing stormwater runoff can be a challenge. Before you buy, look at the contours, slope and natural stormwater pathways of the allotment with your builder. Ideally you don’t want your home design to disturb the natural water-flow and if it does, ensure you make considerations for the water to flow away from your home.

What design considerations do I need to make for stormwater?

If the water on your lot drains to the rear of the property make sure your roof water is connected to stormwater drainage or consider installing a rainwater tank. Look at the use of cut and fill slab design options to ensure water flows away from your home. And where possible explore the use of hard and soft landscaping to avoid soil erosion and maximize natural water flow.

How can stormwater affect earthworks?

Earthworks construction will disturb the soil. If you couple that with stormwater runoff you can have a recipe for a watery-slurry of sediment, plant nutrients, organic matter and waste. Before you start the construction of your home, talk to your builder about managing the sediment and soil erosion on your block of land. You may consider installing fences or bunds to catch sediment and runoff, minimise vehicle access and reduce the vegetation that needs to be cleared.

Both Johnston Ridge and Zuccoli require a Sediment and Erosion Control Plan before work can begin on your home. The plan can be a simple sketch of your block that indicates the measures and controls you’ve put in place.
