DisclaimerThe measures contained in this Bushfire Management Plan are considered to be minimum standards and they do notguarantee that a building will not be damaged in a bushfire. This is substantially due to the unpredictable nature andbehaviour of fire and extreme weather conditions. Additionally, the achievement of and level of implementation ofbushfire management measures will depend, among other things, on the actions of the landowners or occupiers overwhich Bushfire Prone Planning has no control.

All surveys, forecasts, projections and recommendations made in this report associated with the project are made in goodfaith on the basis of information available to Bushfire Prone Planning at the time.

All maps included herein are indicative in nature and are not to be used for accurate calculations.

Notwithstanding anything contained therein, Bushfire Prone Planning will not, except as the law may require, be liablefor any loss or other consequences (whether or not due to the negligence of their consultants, their servants or agents)arising out of the services provided by their consultants.

1 Executive Summary

This Bushfire Management Plan (the Plan) has been prepared to accompany the developmentapplication for a solar photovoltaic panel farm at Lot 1366 Wilson Road, Three Springs within the Shireof Three Springs.

The development site of approximately 270 ha on part of the lot is within a designated bushfire pronearea and the Proposal requires the application of State Planning Policy No. 3.7: Planning in BushfireProne Areas (SPP 3.7). The assessed bushfire risk is considered to be manageable and will be achievedby the identified stakeholders implementing and maintaining the bushfire risk management measuresthat are presented in this Plan.

Assessment of the planned location, vegetation and consideration of planned infrastructure indicatesthat compliance is able to be achieved against all applicable bushfire related legislation, policy,standards and guidelines, including the Bushfire Protection Criteria.

The indicative BAL ratings that can be achieved by all proposed infrastructure is BAL-12.5 with theinstallation of 20m Asset Protection Zones (APZ) comprised of internal road network and low threatvegetation.

Vehicle access to the site will be by existing public roads that are proposed to be upgraded to allow theincreased traffic during construction period and allow semi-trailer vehicles to access the site. Theupgraded roads allow two way access for personnel to access and egress from the site in the event ofa bushfire. The access to the site is through cropped paddocks that allow vehicles to pass through inthe event of any bushfire incidents if required.

All internal access roads will be designed and constructed to allow semi-trailer vehicles access, andappropriate turn around areas that will also be suitable for 3.4 fire appliances. The internal roadnetwork will allow semi-trailer vehicles to move around site to all proposed infrastructure withoutissues.

There is currently a reticulated water supply to the development site for domestic purposes and theclosest hydrant is in the townsite of Three Springs about 28kmwest. It is proposed to install 2 x 50,000ltemergency water tanks for emergency services to utilise with the appropriate fittings and 3.4 fireappliance hardstand.

The existing homestead onsite has a BAL rating of BAL-12.5 that will be maintained with theappropriate separation distances. The proposed temporary workers accommodation to be utilisedduring the construction period for ~150 workers will be located in a BAL-12.5 area once the 20m APZis installed.

Future buildings within 100 metres of classified vegetation will be constructed to standards whichcorrespond to the determined BALs, as required by AS 3959-2009 Construction of buildings in bushfireprone areas.


Implementation of a Asset Protection Zone (APZ) of 20m is proposed to be established around allproposed infrastructure including solar array, storage building, substation, temporary workersaccommodation and existing homestead. The visitors interpretation area will be comprised of acarpark, managed gardens, playground and ablution block and will be surrounded by low threatvegetation.

The proposed development of the solar array with a designed output to be 150MW to be linked intothe power grid is of a size that is classified as a high risk land use. The proposed development willgenerate power from solar photovoltaic (PV) panels within an existing cropped paddock.

At future planning stages an overall risk management plan will be developed for the construction andoperation stages of the development. This overall risk management plan will address bushfire risk andimplement mitigation and response procedures for bushfire related incidents.


2 Application of SPP 3.7

The State Planning Policy No. 3.7: Planning in Bushfire Prone Areas (SPP 3.7) provides the foundationfor land use planning to address bushfire risk in Western Australia.

This Proposal must consider SPP 3.7 and, if required, comply with its policy measures. Thedetermination of this requirement is presented below.

Application of SPP 3.7 Policy Measures – Primary Triggers

The subject Proposal is a higher order strategic planning document, a strategic planningproposal or a subdivision or development application:

The project site is in a designated bushfire prone area on the WAMap of Bushfire ProneAreas:

The project site is not located in a designated bushfire prone area on the WA Map ofBushfire Prone Areas but the existing vegetation type and condition dictate that itshould be:

The project site is in an area not yet designated as bushfire prone but is proposed to bedeveloped in a way that introduces a bushfire hazard (Guidelines for Planning in BushfireProne Areas WAPC v1.1 2017 s3.2.2):

Application of SPP 3.7 Policy Measures – Secondary Trigger/s

The Proposal is a strategic planning proposal, subdivision or development applicationrelating to land that has or will have a Bushfire Hazard Level above low and/or where aBushfire Attack Level rating above BAL-LOW applies (SPP 3.7 s6.2):The subject Proposal is a development application for the construction or/and use of asingle house or ancillary dwelling on a lot or lots greater than 1100m2 and subject toBAL-40 or BAL-FZ (LPS Amendment Regulations 2015):

The subject Proposal is a development application for the construction or/and use of ahabitable building (other than a single house or ancillary dwelling), or a specifiedbuilding on any lot size and subject to a BAL rating above BAL-LOW (LPS AmendmentRegulations 2015):


3 Commissioning and the Land Use Proposal

4 The Planning Submission and the Documents Required

Policy measures in SPP 3.7 (and further instruction in the associated document Guidelines for Planningin Bushfire Prone Areas WAPC v1.1 2017) set out the bushfire planning information (including bushfirerisk assessments) that are to accompany a planning submission. It is dependent on the type of proposaland stage of the development process. In most circumstances this information is to be presented inthe form of a Bushfire Management Plan (BMP).

This Bushfire Management Plan will include the information indicated by the check mark. If an item ischecked it is required by either: SPP 3.7 or by a local government variation. It may also have beenprepared at an earlier planning stage and therefore re-included or included by the assessor as itimproves the information presented in this Bushfire Management Plan.
