Bushfire Landscape Assessment

Refer t o pages 17 t o 2 5 o f Practice Note 6 5 fo r details to assist in developing a Bushfire Hazard Landscape Assessment.

Which landscape scenario represents t h e site? (Refer to Practice Note 65 for descriptions) T h e l andscape scenar io t h a t r e p r e s e n t s th is is Landscape Scenar io 3.

W h a t is t h e likely f ire behaviour impacting t h e site? It is considered tha t t h e fire risk from t h e wider l andscape is no g rea te r than that assumed by AS3959 a n d therefore adequate ly dea l t with by t h e V P P defendable s p a c e tab les The main fire w e a t h e r c o m e s from t h e South Eas t followed by t h e South-West. T o t h e North- W e s t it is mainly g razed Grass land without sufficient e x p a n s e of Forest to c r ea t e an ex t reme fire. W e m u s t a s s u m e that t h e south w e s t a r e a will enab le a s t e ady s ta te fuel load roughly in a c c o r d a n c e with AS3959. It will b e possible in t h e future for ano the r significant fire to g o through this a r e a however w e believe it will b e no grea te r than that a s s u m e d by AS3959. In a n e v e n t of a bushfire s p r e a d t h e m o s t likely direction would per ta in from t h e s o u t h w e s t direction with t h e d e n s e vege ta t ion . Worse c a s e scenar io fires in hushland can be hot, intense and fast moving with burning embers possibly blowning from the bush, landing on the property and starting spot fires or setting fire to the home, embers may land for many hours even after the main fire front has passed. Smoke and lire may aflect driveways or homes, making it difficult to leave. The radiant heat from a fire nearby may set fire to the property or surrounds. T h e r e a r e a n u m b e r o f t h ings which can af fec t t h e w a y a fire burns , including: Slope - a fire travelling uphill will travel faster. In fact, for every 10 degrees o f slope. a fire can double its speed. As a lire speeds up, it becomes more intense and more dangerous. Vegetation - smaller items such as twigs, branches and leaves are known as 'tine fuels'. These can burn very easily. Burning bark, twigs and leaves can also be blown in the wind. Weather - when it's hot, dry and windy, tires can be more intense and unpredictable. Strong winds can send a lire in di if èrent directions and cause burning embers to he blown through the air . The type and extent of vegetation located more than 150 metres from the site may result in neighbourhood-scale destruction as it interacts with the bushfire hazard on and close to a site. Bushfire can approach from more than one aspectas shown on the overall SOOm+ aerial plan. The site is located in an area that is not managed in a minimum fuel condition. Access to an appropriate place that provides shelter from bushfire is not certain. The design of the building to the appropriate BAL level will reduce the risk of entry of embers as far as practical. The risk of accumulation of debris has been reduced by the adoption of the appropriate vegetation modifications and management standards. Gutter guards will be fitted to the roof The building is rectangular with no re-entrant corners and with a simple roof line with no valley gutters. Defendable space will be provided as demonstrated by the compliance with all applicable Approved Measures and/or Alternative Measures it can be shown that this development has reduced the Bushfire risk to an acceptable level. The site will meet the Defendable Space requirements of the "BMO" when calculated with the relevant VPP Table.

Approved Measure AM 2.2 - Siting

Requirement

A building is sited to ensure the site best achieves the following:

• The max imum separation distance between the building and the bushfire hazard

43m mm.

The building is in close proximity to a public road

The proposed location of the development on the site allows for an acceptable level of bushfire protection given the surrounding vegetation types and likely location of a fire front.

The dwelling will be located on the South side of the un-sealed road (Le Bruns) and approximately 350mtr from the roadway.

The site has minimal opportunities for considering slope of the land

The proposed dwelling will have a BAL 29 requirements under Building Regulation - 2006

Are there significant siting constraints that would allow Column D o f Table 2 to Clause 52.47-3?

Yes 1 ' No E l Not Applicable El

The site has minimal siting opportunities considering the slope of the land and shape of the site. The chosen location is the most suitable to the site. Column C has been chosen to give the uttermost protection to the building and surrounding properties. With the construction of the new dwelling and habitaiotn it wil provide the abilty to manage the site more effectively providing a safer environment for the site and any surrounding properties

A building is constructed to t h e bushfire at tack level:

• That corresponds to the defendable space provided in accordance with Table 1 to Clause 52.47-3. The building will be constructed to BAL 29

I s t h e defendable space whol ly contained wi thin the boundaries of your property?

Yes E l No if no, see Alternative Measure 3.3

Any other comments
