Wind, bushfire and site conditions in Castle Hill
Castle Hill is hilly, with bushland reserves and creek lines running between the streets. Some lots near bushland are mapped as bush fire prone, which brings a bushfire attack level assessment and construction requirements for new work. The wind classification is set for each lot by the engineer and governs bracing and tie down. On ridges and slopes, the way stormwater is collected and carried away matters, which is why rainheads, box gutters and downpipes appear so often in our reports.
Check The Hills Shire bush fire prone land map for your lot.
Bush fire prone lots need a BAL assessment for new work.
Wind class is set lot by lot and drives bracing.
Sloping blocks need careful stormwater design.
Rainheads need overflows so a blockage does not flood a wall.
