1. Introduction

1.1 Background

Shire of Bridgetown-Greenbushes and Shire of Nannup (the Shires) do not currently have an overall approach to bush fire risk management at a community and land development level. This can potentially lead to inadequate bush fire management for new land developments and communities, which was illustrated to be a contributing factor to the loss of significant property assets in the Perth Hills bush fires on 6 February 2011 (Keelty 2011). Given the inherent bush fire risk due to the vast availability of bush fire fuels located within the Shires, an approach that links bush fire management planning processes and building enforcement aspects is critical to the protection of existing life and property assets and those arising from proposed future development.

The current approach to bush fire management and protection across the Shires is through Fire Management Plans prepared and implemented during the latter stages of the planning process, or in a responsive manner through enforcement powers granted under the Bush Fires Act 1954 and relevant local laws. However, the bush fire planning principles contained within Planning for Bush Fire Protection Guidelines (Edition 2) (the Guidelines – WAPC et al. 2010), Australian Standard AS 3959 – 2009 Construction of buildings in bushfire prone areas (SA 2009a) and the recommendations from Keelty (2011) place further onus on local governments to be more proactive in providing a better approach to bush fire management when planning land developments and establishing new communities.

In light of this, the Shires have commissioned Strategen to prepare a Bush Fire Hazard Strategy across both Shires in accordance with the Guidelines.

1.2 Purpose and scope

The purpose of this Bush Fire Management Strategy is to inform bush fire management planning requirements for any future development within the Shires through the application of Australian Standard AS 3959 – 2009 Construction of buildings in bushfire prone areas (SA 2009a).

The strategy is based on bush fire hazard assessment mapping that was undertaken in accordance with the Guidelines across both Shires to determine bush fire prone areas. Identification of bush fire prone areas subsequently enables the application of AS 3959 – 2009, which outlines appropriate construction standards for buildings proposed for such areas.

The following provides a brief overview of the methodology used in determining bush fire prone areas across the Shires: • a desktop investigation to identify vegetated areas of both Shires and the corresponding vegetation types, as well as the average slope under each classified vegetation type • targeted field assessments to visually confirm results from the desktop investigation • preparation of a vegetation class map and average slope map for each Shire based on the desktop and field investigations • preparation of a bush fire hazard assessment map for each Shire based on the vegetation and slope assessments • preparation of a bush fire prone areas map for each Shire based on the hazard levels determined.

Methodology used to determine bush fire prone areas is discussed in detail in Section 3, followed by an outline of the existing environment across the Shires in the context of bush fire management (Section 4). Some examples of project mapping outputs are provided in Section 5; however, the full extent of project mapping deliverables is contained on disc for Shire use. A summary of the stakeholder consultation is outlined in Section 6 and key project outcomes and conclusions are provided in Section 7.

2. Aim and objective

2.1 Aim

Local governments are obliged to assist in the protection of life and property assets from bush fire. The Shires do not currently have an overall approach to bush fire risk management at a community and land development level.

This document aims to integrate bush fire management, as specified in the Guidelines, into future land development and planning processes across the Shires through the identification of bush fire prone areas and application of AS 3959 – 2009.

2.2 Objective

The objectives of the Bush Fire Hazard Strategy are to: 1. Identify site suitability of subdivision and development through an assessment of vegetation and bush fire hazard levels, which reflect the Guidelines and AS 3959 – 2009. 2. Give direction to both Shires, Department of Planning (DoP), Western Australian Planning Commission (WAPC) and the Minister for Planning in assessment of local planning scheme amendments, structure plans, subdivision applications, development applications and building applications and provide fire planning support for this decision making. 3. Improve awareness and develop procedures for the implementation of the Bush Fire Hazard Strategy through training of the Shires’ Fire and Emergency Services, Planning and Building personnel.

3. Project approach and methodology

The following subsections provide a detailed outline of the approach and methodology used to determine bush fire prone areas across the Shires, which is consistent with the methodology outlined in the Guidelines and AS 3959 – 2009.

3.1 Determination of vegetation type and class

The main fuel for a bushfire comprises vegetation, litter and debris that accumulates on the ground. The type and extent of fuel on the ground depends on the type of vegetation that produces the fuel (SA 2009). Vegetation type and class across the Shires was determined through a combination of a desktop investigation and targeted field assessments and was characterised as per the descriptions outlined in Table 1 and Figure 1 of the Guidelines (derived from AS 3959 – 2009), which have been replicated as Table 1 and Figure 1 of this document.

3.1.1 Desktop investigation

The desktop component involved vegetation aerial imagery mapping and data analysis to determine the general vegetation types and classes occurring across the Shires. This included assessment of vegetation mapping undertaken by Mattiske and Havel (1998), as well as assessment of satellite aerial imagery maps to identify the predominant areas of vegetation occurring throughout the Shires.

3.1.2 Field assessments

Following the desktop component, field assessments were undertaken to ground truth vegetation types throughout vegetated areas of the Shires that required further clarification. The field assessments also helped determine approximate bush fire fuel loads at each site, taking into account the slope, predominant flora species, vegetation density, litter depth, trash height, trash density, scrub structure, scrub density, scrub height and foliage density. Bridgetown-Greenbushes Shire staff accompanied Strategen during the field vegetation assessments to assist with Shire training.

3.1.3 Mapping output

Completion of the desktop and fieldwork components enabled the development of a vegetation class map for each Shire. The maps outline the location of predominant vegetation complexes throughout the Shires and some examples have been provided in Section 5.1. A broad, written description of the vegetation types and fuel loads determined, as well as photos of each vegetation type has been included in Section 4. Vegetation types greater than 0.25 ha were identified and mapped and any vegetation types smaller than 0.25 ha were identified and mapped as required, as per the Guidelines.

3.2 Determination of average slope

The slope of the land under the classified vegetation has a direct influence on the rate of fire spread, the severity of the fire and the ultimate level of radiant heat flux. There are two significant topographical influences on the intensity and speed of a bush fire (AS 2009b): 1. Aspect – every hill has more than one side or aspect. Fuel on aspects shielded from moist breezes or exposed to the drying impact of the sun or wind is likely to be drier than fuel on other aspects not so exposed or shielded. 2. Slope – the effective slope of the ground under the vegetation has a marked impact on the intensity and speed of the fire above that ground.

The steepness of the slope evidently impacts on the speed and intensity of the fire front. When a fire front is moving uphill, then the steeper the slope, the closer the ground fuel is brought to the radiant heat from the fire front and the shorter the time to ignition. This increases the rate of spread and the intensity of the fire. The greater the intensity of the fire, the easier it is for the fire to overcome any discontinuities of fuel (AS 2009b).

3.2.1 Desktop and field assessments of slope

The slope of the assessment area was determined using a combination of desktop contour mapping and targeted field assessments. The desktop component provided a broad scale overview of Shire topography through the application of GIS contour data. The field assessments allowed slope to be assessed at targeted sites that required further clarification.

3.2.2 Mapping output

Completion of the mapping and fieldwork components enabled the development of an average slope map for each Shire. The maps illustrate variations in slope across both Shires and some examples have been provided in Section 5.2.

3.3 Determination of bush fire hazard levels

Classifying the bush fire hazard level through the assessment of the predominant vegetation and slope is a key to the initial determination of site suitability for subdivision and development; and if deemed suitable, the potential level of construction standard determined by the application of the AS 3959 – 2009 at the subdivision and development stage.

3.3.1 Bush fire hazard level determination

Depending on the predominant vegetation (type and class), fuel load (in tonnes per hectare) and the slope of the land, bush fire hazard levels designated as low, moderate and extreme were applied to different areas of the Shires in accordance with the Guidelines. Bush fire hazard levels are outlined in Table 2 (WAPC et al. 2010).

Table 2 Bush fire hazard levels

Bush fire hazard Description level Open woodlands Open shrublands Low shrubs with slopes of less than 10° or flat land Suburban areas with some native tree cover Extreme Forests Woodlands Tall shrubs

3.3.2 Mapping output

The methodology described in Sections 3.1 and 3.2 enabled the development of a bush fire hazard assessment map for each Shire. The maps illustrate land designated as low, moderate or extreme bush fire hazard based on vegetation type, available fuel load and slope. Some examples have been provided in Section 5.3 and all of the Shire information is presented on CD with this report. Determination of bush fire hazard areas can inform the location of future development areas, as well as identify whether any future subdivision or development areas will require heightened levels of both strategic and or individual lot bush fire management, such as increasing the BAL (Bush fire Attack Level) to a maximum of BAL 40 (allowed by FESA in the Western Australian context) and corresponding construction standards to ensure that life and property of these areas is adequately protected.

3.4 Determination of bush fire prone areas

The low, moderate and extreme bush fire hazard levels specified in the bush fire hazard assessment map enabled the development of a bush fire prone areas map. This map specifies bush fire prone areas across the Shires, which can assist future planning and development at the strategic level and help inform the level of bush fire management required in specific areas (i.e. this enable the Shires to implement AS 3959 – 2009). Some examples have been provided in Section 5.4.

The methodology for determining bush fire prone land is clearly explained in the Guidelines, which states that all areas with an assessed moderate or extreme bush fire hazard level are considered to be bush fire prone areas. The measurable parameters that determine the bush fire hazard level of a particular area; and subsequently the bush fire prone status of the land, are explained progressively in Sections 3.1 and 3.2 of this section and include the type and class of vegetation, the available fuels, the position in the landscape (aspect) and slope.

Bush fire prone land, as determined in this assessment, will be designated in consultation with the Shires, WAPC and FESA in accordance with the Guidelines.

3.5 Stakeholder consultation

The stakeholder consultation component of the project included comprehensive training of Shire staff and close liaison with Shire and other government agency representatives (e.g. FESA). Stakeholder consultation is further discussed in Section 6.

3.6 Preparation of a Bush Fire Hazard Strategy

The tasks detailed in the above sections enabled the preparation of this document, which, as discussed in Section 2, aims to integrate bush fire management into future land development and planning processes across the Shires through the identification of bush fire prone areas and application of AS 3959 – 2009.

4. Existing environment

The following subsections provide an overview of the existing environment across each Shire in the context of bush fire management.

4.1 General description of the area

The assessment area encompasses all land comprised by Shire of Bridgetown-Greenbushes (1691 km2 of which approximately 47% is State Forest) and Shire of Nannup (2953 km2 of which approximately 83% is State Forest). The Shires are located in the South West Region of Western Australia, approximately 270 kilometres south of Perth (Figure 2). Shire of Nannup maintains 30 km of coastline to the south.

Generally, the key land uses include forestry (native forest and plantation) and conservation, which feature prominently across both Shires; along with general agriculture (grazing of improved pastures, dairying, dry land agriculture) and State Forest surrounding local townsites. Other land uses include mining, rural residential, easements for roads and power lines, urban areas and irrigated viticulture and horticulture. The recent increase in residential, rural residential and special rural subdivisions throughout the Shires will require an increase in the fire protection requirements in these areas.

4.1.1 Bioregional context

Interim Biogeographic Regionalisation for Australia (IBRA) divides Western Australia into 26 biogeographic regions and 53 subregions based on dominant landscape characteristics of climate, lithology, geology, landform and vegetation (McKenzie et al. 2003). The Shires lie predominantly in the Jarrah Forest bioregion (Southern Jarrah Forest subregion), but southern portions of both Shires also fall within the Warren bioregion. Table 3 outlines bioregional characteristics of both bioregions (taken from McKenzie et al. 2003).

4.2 Climate

The Shires generally experience a temperate climate characterised by mild, wet winters and warm to hot, dry summers. Rainfall may occur at any time of the year; however, most occurs in winter in association with cold fronts originating from the southwest. A cool to mild growing season occurs in the months of August through to December of each year followed by three to four months of summer drought conditions, which is when the potential for wildfire occurrence is at its peak. The worst fire weather conditions occur when a low pressure trough forms off the west coast and strong, hot, dry winds develop from the north.

4.3 Topography

Topography varies across the Shires ranging from moderately sloped, undulating farmland through to heavily vegetated, steep river valleys. Topography of the Shires is further discussed in Section 5.2, which provides an average slope map for each Shire.

4.4 Vegetation

Vegetation types across the Shires vary, where the majority of remaining vegetated land comprises a combination of forest (Plate 1 and Plate 2), woodland (Plate 3), shrubland (Plate 4) and plantation forest (Plate 5). Average available fuel loads are discussed in Section 4.5 and a broad, written description of the vegetation types mapped across each Shire is outlined in Section 5.1.

4.5 Available bush fire fuels

The availability of bush fire fuels is measured in tonnes per hectare (t/ha) and can vary depending on a number of factors, such as flora species, vegetation density, litter depth, trash height, trash density, scrub structure, scrub density, scrub height and foliage density. Fuel availability can also be reduced through prescribed burning and the occurrence of uncontrolled bush fires, both of which have occurred at various intensities and locations across the Shires in the last decade. Given the range of vegetation types observed and the varying extent of fuel hazard reduction throughout each Shire, the resulting fuel loads across the Shires for each vegetation type vary significantly. Table 4 outlines the general availability of fuel loads observed, along with fuel accumulation rates and the maximum fuel load thresholds that are generally recommended.

4.6 Summary of bush fire history

Given the likelihood of ignition, vegetation extent and availability of bush fire fuels across both Shires, there is an inherent risk of ignition and wildfire occurrence, especially during extreme and catastrophic fire weather conditions. Evidence of this is provided during the last decade, where a number of uncontrolled bush fires have occurred throughout both Shires. Recent examples cited by council staff are contained in Section 4.6.1 and Section 4.6.2.

4.6.1 Shire of Bridgetown-Greenbushes

Shire of Bridgetown-Greenbushes experienced a particularly severe uncontrolled bush fire on 27 December 2003, where a total of 4666 ha was burnt and two houses were destroyed (Shire of Bridgetown-Greenbushes 2007). A subsequent uncontrolled bush fire in February 2004 also resulted in the loss of a volunteer fire-fighter. The most recent uncontrolled bush fire was in January 2009, which burnt 5800 ha with losses including seven houses, plantation land, private property and a bridge (Sousa C [Shire of Bridgetown-Greenbushes] 2012, pers. comm. 23 February).

4.6.2 Shire of Nannup

The most recent uncontrolled bush fire in Shire of Nannup occurred during November and early December 2011, which burnt more than 55 000 ha around Milyeanup to the southwest of Nannup. No lives or houses were lost in this instance. Shire of Nannup has experienced numerous other uncontrolled bush fires within the last two years that placed lives and properties at risk including the Layman Block Fire (November 2010), the North Nannup Fire (November 2010) and the Donnelly River Fire (December 2010) (Levick- Godwin T [Shire of Nannup] 2012, pers. comm. 1 March).

4.7 Assets

The Shires contain a range of community and natural assets that are at risk of loss or damage from uncontrolled bush fire in the form of critical life and property assets within townsites, localities and agricultural properties; along with environmental assets in the form of conservation significant flora, fauna and habitat; and heritage assets in the form of European and Aboriginal heritage sites. The predominant critical assets are associated with populated areas of each Shire, including: • for Shire of Bridgetown-Greenbushes – four townsites including Bridgetown, Greenbushes, North Greenbushes and Hester; and several surrounding localities including Catterick, Yornup, Kangaroo Gully, Sunnyside, Maranup, Winnejup and Wandillup • for Shire of Nannup – one townsite being Nannup; and several surrounding localities including Darradup, Carlotta, Jalbarragup, Scott River, Nannup Brook/East Nannup and North Nannup.

5. Project mapping deliverables

Desktop and field assessments outlined in Section 3 enabled the determination of the following components across each Shire: • vegetation type • slope • bush fire hazard levels • bush fire prone areas.

Each of the abovementioned components were mapped across each Shire, which was a key project outcome to enable implementation of AS 3959 – 2009. An example of each mapping component, along with detailed map descriptions and interpretation has been provided in the following subsections for both Shires. The full suite of bush fire mapping for each Shire has been provided on disk to the Shires, given the file size of the mapping component.

5.1 Vegetation class map

Vegetation throughout each Shire was assessed in accordance with mapping undertaken by Mattiske and Havel (1998), in which vegetation complexes were assessed together with visual field assessments, enabling the preparation of a Vegetation Class Map for each Shire (examples illustrated in Figure 3, Figure 4 and Figure 5, and a complete description of vegetation complexes outlined in Appendix 1). Vegetation complexes were then cross-referenced with the class and type descriptions outlined in Table 1 and Figure 1 so that vegetation class and type across the Shires could be determined (outlined in Table 5 and Table 6).

Forest and woodland vegetation types (described in Plate 1, Plate 2 and Plate 3) exist prominently throughout both Shires in the form of jarrah, marri and karri forest; and peppermint/eucalypt woodland. Shrubland vegetation types occur to a lesser degree along coastal areas of the Shire of Nannup in the form of coastal heath.

5.2 Average slope map

Contours of 50 m intervals were obtained from Geoscience Australia (2006), which enabled the preparation of an average slope map for each Shire (examples illustrated in Figure 6, Figure 7 and Figure 8). Steeper terrain generally carries a higher bush fire risk and hazard level compared to flat or undulating terrain. These areas can be inferred from the average slope map and have been taken into consideration in the mapping of bush fire hazard levels.

Shire of Bridgetown-Greenbushes consists of moderately sloped, undulating farmland and forest in the north and south of the Shire at around 250 – 300 m AHD (Australian Height Datum). However, steeper terrain occurs across the central parts of the Shire in an east-west direction in association with the Blackwood River, which produces numerous, heavily vegetated, steep river valleys at around 200 – 300 m AHD.

The central and western portions of the Shire of Nannup experience undulating to flat topography that slopes very gently from north to south via low-lying sunklands at 100 – 150 m AHD, the Scott Coastal Plain at 50 m AHD and eventually the coast. The bulk of this area is vegetated with the exception of some cleared land for irrigated agriculture throughout the Scott Coastal Plain. However, the eastern portion of the Shire consists of the southern extremities of the Darling Scarp, which contains numerous small valleys and slopes gradually from the north at 350 m AHD to the coast.

5.3 Bush fire hazard assessment map

The steps taken to determine vegetation types and slope across the Shires eventually enable the determination of bush fire hazard levels. Vegetation type was the key determinant of bush fire hazard level, given the Shires’ large extent of densely vegetated forest, woodland or shrubland areas greater than 0.25 ha. These areas were assigned a moderate to extreme bush fire hazard level regardless of slope. A 100 m buffer zone was also included around these areas to capture any developments proposing to be located within 100 m of moderate to extreme bush fire hazard areas. Cleared farmland and urban areas lying outside the 100 m buffer were assigned a low bush fire hazard level. Mapping of the bush fire hazard levels resulted in the preparation of a bush fire hazard assessment map (examples illustrated in Figure 9, Figure 10 and Figure 11).

The average slope maps illustrate areas where steep terrain may occur, which provides a useful guide for where further assessment of slope at a subdivision or lot scale may be required. However, as the contour mapping was undertaken at 50 m intervals at a Shire level, accurate, site specific estimations of slope could not be determined in this case. This is not expected to affect the determination of bush fire hazard levels, as the Guidelines recommend that any areas of forest, woodland or tall shrubs should generally be assigned an extreme bush fire hazard level.

5.4 Bush fire prone areas map

The Guidelines specify that all areas with an assessed moderate or extreme bush fire hazard level are considered to be bush fire prone areas. Therefore, those areas of the Shires falling within the moderate to extreme bush fire hazard level areas (as illustrated in the bush fire hazard assessment maps) form designated bush fire prone areas.

This assessment enabled the preparation of a bush fire prone areas map for each Shire (examples illustrated in Figure 12, Figure 13 and Figure 14). The majority of both Shires have been designated as bush fire prone due the large extent of vegetated land occurring throughout both Shires.

Bush fire prone land, as determined in this assessment, will be gazetted in consultation with the Shires, WAPC and FESA in accordance with the Guidelines. Assignment of Shire, WAPC and FESA-approved bush fire prone land will allow: 1. the identification of any proposed subdivision, development or modification to an existing building occurring within a bush fire prone area 2. subsequent implementation of Shire policies relating to the level of bush fire assessment needed for the proposed development prior to construction (BAL assessment, Fire Management Plan, etc) 3. subsequent implementation of appropriate bush fire management measures early in the planning stages of the development (specifically building location and setback requirements, level of construction standard as per AS 3959 – 2009, hazard separation zones, building protection zones, fuel hazard reduction, access requirements and water requirements).

6. Stakeholder consultation

6.1 Overview

Preparation of the bush fire hazard strategy involved consultation with shire staff, which included two key elements: • Shire staff training • local government liaison.

These are discussed in the following subsections.

6.2 Shire staff training

A training package was prepared and delivered to each Shire to help inform Shire personnel of the operation of bush fire hazard ratings, bush fire prone areas and implementation of AS 3959 – 2009. The training day encompassed the following: • bush fire behaviour • bush fire attack methodologies with AS 3959 – 2009 • explanation of BALs • BCA classes in bush fire prone areas • AS 3959 – 2009 changes from 1999 • general construction requirements • site assessment and role of vegetation and slopes • mapping of bush fire prone areas • submission requirements • assessment check sheets and recommendations.

A BAL site assessment form was prepared to assist building surveyors and Shire staff in confirming that a Building License Application meets the current requirements of AS 3959 – 2009 (refer to Appendix 2 for a generic BAL assessment form).

6.3 Local government liaison

Strategen maintained close liaison with the following Shire representatives throughout the preparation of the bush fire hazard strategies for both Shires: • Chief Executive Officer • Community Emergency Services Manager • Manager/Planning/Manager Development Services.

An additional presentation was provided to Shire of Nannup council representatives and staff to reiterate the outcomes of the bush fire hazard strategy.

SBN11188_02_R001 Rev 0 11-Jul-13 35 Bush fire hazard strategy

7. Key project outcomes and conclusions

This bush fire hazard strategy has been prepared to provide direction to Shire of Bridgetown-Greenbushes and Shire of Nannup, DoP, WAPC and the Minister for Planning in the assessment of future local planning scheme amendments, structure plans, subdivision applications, development applications and building applications for each Shire, as well as provide fire planning support for this decision making.

The strategy classifies the bush fire prone areas of each Shire so that bush fire planning policies and subsequent management measures can be implemented in the early planning stages of proposed developments, especially through the enforcement of AS 3959 – 2009.

This was made possible through the assessment and mapping of vegetation and slope and the subsequent determination of bush fire hazard levels and bush fire prone areas of each Shire in accordance with methodology outlined in Planning for Bush Fire Protection Guidelines (Edition 2) (WAPC et al. 2010) and AS 3959 – 2009 Construction of buildings in bushfire prone areas (SA 2009a).

The strategy determined that bush fire prone areas occur prominently throughout both Shires in association with vast amounts of vegetated land contained on private property and throughout the conservation estate. The full extent of vegetation, slope, bush fire hazard levels and bush fire prone areas mapping for each Shire can be found on disks with supporting information submitted with this document.

Another key component of the strategy was to undertake Shire staff training to inform Shire personnel of the operation of bush fire hazard ratings, bush fire prone areas and implementation of AS 3959 – 2009, as well as improve awareness and develop procedures for the implementation of the Bush Fire Hazard Strategy. Presentations were provided to both Shires, as well as an interactive field component demonstrating the assessment of vegetation, slope and subsequent bush fire hazard rating of a site.

Strategen is able to provide additional information and training, along with follow-up presentations to both Shire councils on request.
