Building with Bushfire Compliance
Our state has seen significant growth in the last 10 years, due to the urban sprawl further out of the Sydney Metropolitan area. Covid-19 has also been a big influence on people searching to find a more peaceful and spacious lifestyle.
We are proud to call The Hawkesbury region our home, and love the beauty which the Blue Mountains brings to our local area. Unfortunately, with the beauty of the Blue Mountains, also comes the risk of bush fire.
We are huge advocates for providing as much protection as possible to homes and property in the unfortunate event of a bush fire. The majority of these control measures could also be applied to existing homes if you are concerned about bush fire risk.
We have lots of experience in building beautiful family homes which require specific measures for bush fire protection. Bushfire compliance can seem overwhelming and daunting, but it doesn’t have to be!!
Could my property be affected by a BAL rating?
To put it simply, any property with natural vegetation, grasslands, paddocks or bush, especially within the Hawkesbury can be subject to a BAL rating (Bushfire Attack Level rating). This is a rating which measures the risk of fire specific to your property, as well as other contributing factors such as slope.
How do I determine what the BAL rating is for my property?
Easy, we have an experienced Bush fire consultant, who can come out and conduct a BAL Assessment for you.
However, If you are at the early stages and looking at purchasing a property, we recommend asking your conveyancer to investigate the BAL rating so that you are aware what risk is imposed on the parcel of land, especially if you are thinking of building or renovating on the property.
The NSW Rural Fire Service provide the following explanation for each of the BAL ratings in their Planning for Bush Fire Protection 2019 report, which can be viewed on their website at https://www.rfs.nsw.gov.au/__data/assets/pdf_file/0005/174272/Planning-for-Bush-Fire-Protection-2019.pdf
Our recommendations for building with bushfire & why:
Gutter Guard
Not only is it a requirement for specific BAL ratings, however gutter protection protects your gutters from leaf matter which over time builds up, breaks down and can cause rust in your gutters. Installing gutter guard also means that you are not jumping up on the roof to clean your gutters from leaves every 6-12 months - and lets face it, who has time for that!
Its important to note, that there are lots of off the shelf gutter protection products on the market, however we recommend being cautious as depending on the product you choose you need to make sure your gutters will not be obstructed as this could limit the water which flows into your gutters especially if you exclusively rely on tank water.
Water Tanks
There are a wide range of water tanks both inground and above ground, they can be made of concrete, metal and poly, and come in various shapes and sizes. Although sometimes they are not the most appealing item to have in your yard or surrounding your beautiful new home, there are some clever ways you can deal with this… why not incorporate water storage underground? Did you know you can create water storage under your driveway!? Water tanks can also be incorporated underneath decks and alfresco areas. These options are great as they are out of sight and out of mind - best thing is you'll have water storage for your gardens and to protect your property and you cannot see it! Please note - these options are always created with the consultation of a structural engineer specific to each property and need to comply with any requirements for bushfire protection. Alternatively, firepits look great on top of inground concrete water tanks!
Shutters
For homes which have a rating of BAL-40 & BAL-FZ shutters are a requirement, and understandably so. Thinking about this at the preliminary stage also ensures that you are not subject to a variation during construction which could blow out your budget.
Screens
For your windows and doors we recommend metal screens as opposed to fibreglass mesh. Your BAL rating could mean you require Aluminium or Stainless Steel screens, this is because flying embers can travel a distance and create holes in your screens. Regardless, we don’t recommend fibreglass screens for any home as over time with ongoing sun exposure, the fibreglass becomes brittle and breaks.
Fire retardant plants
Obviously landscaping plays a huge part in adding visual appeal to any new home, however did you know that there are plants which are accelerants and retardants to fire? Some plants ignite with heat and others do not, in fact the retardant plants can be far more resilient to heat and ongoing dry weather.
Selecting fire retardant plants could provide an additional barrier to protect your home, and be better at surviving if subject to flying embers.
Access
Its important to consider the access in and around your property for a fire truck. The RFS need to have clear unobstructed access to be able to get to your dedicated firefighting water supply tank as well as offer their assistance in protecting your home and assets in a fire. NSW RFS require 4m wide x 4m high clear path suitable for their fire trucks. Limited access could limit their ability to protect your home.
Asset Protection Zone
The NSW Rural Fire Service strongly recommend allowing for a protection zone around your home. This is designed to provide access in the event the RFS need to attend your property to protect your home. A break from any vegetation or grassland to your home also reduces fuel for a bushfire.
Irrigation
When you think about how you want to landscape your new home we recommend thinking about how to irrigate your gardens and lawns also. Not only will this reduce the maintenance around your property for all year round care but provides a system to protect your home from flying embers in the event a fire is close by.
Storz Fittings
Firstly, what is a storz fitting you ask? … Storz fittings are the fittings which the NSW RFS hook up to when they access your dedicated water supply tank in the event of a bush fire. In addition to the access for the RFS and dedicated water tanks its good to think about where the storz fittings on the tanks need to be placed so that the NSW RFS can easily access the fittings to connect to your onsite water storage tanks. In an emergency its really important that the NSW RFS can quickly & easily access tanks and their fittings.
PROBABLY THE MOST IMPORTANT THING YOU NEED TO DO… Prepare a Bushfire Plan!
The NSW Rural fire service have some great resources online designed to inform home owners on the best way to protect their homes. We recommend sitting down with a coffee and having a look at ways to better prepare your home for bushfire seasons, and plan for an urgent evacuation. Planning ahead provides peace of mind in an emergency. Download your bushfire survival plan here https://www.rfs.nsw.gov.au/resources/bush-fire-survival-plan
