2 What is this all about?

3 Risk is applied in many professions Legal, Financial, OH&S, Enterprise, Emergency/Disaster Management Source: QldRA, 2012 There are also many technical definitions of risk and risk assessment/management We even have an Australian & New Zealand Standard for it (AS/NZS ISO 31000:2009) but in simple English? Risk is the chance of something happening and the impact of it when it does Source: mandjsfitness.wordpress.com/2012/05/

4 What is this all about?

5 Governments are seeking ways to cut red (and green ) tape, simplify approvals processes and focus on strategic planning Planners already understand that bureaucratic processes don t help anyone but if protecting our communities from poor development is paramount Source: onthehouse.com.au Source: phys.org Source: The Age Newspaper

6 let s consider the views of the community, politicians and industry players and think outside the box on how we might improve our land use strategies, planning instruments and development assessment processes Plan strategically rather than relying on case-by-case assessment applications streamed into riskbased assessment tracks matching the level of assessment with the level of risk and impact of a development

8 Recent Policy Work in Queensland Improve Planners understanding of flood risk Flood Risk = Consequence x Likelihood Tools to support land use planning strategies and responses Less reliance on development assessment (DA) Front load planning schemes to reduce reliance on DA

9 The Planning Evaluation Planning Evaluation = planning oriented risk assessment process Investigates relationship between flood hazard areas & land use to identify areas of risk (low, medium and high) to clarify land use intent and avoid internal conflicts in planning scheme Develop planning responses to each area of risk Maintain the status quo Adapt existing areas Retreat from specific existing urban areas Expand into suitable new urban areas Maintain agricultural and rural landscape values Source: QldRA, 2012

10 Consequence Equation Source: QldRA, 2012 Exposure relates to hazard severity created by flood event per land use Vulnerability identifies characteristics of land use and built form affected Tolerability relates to matters that may reduce risk/impact of flood Source: QldRA, 2012

11 Exposure a very large and toothy shark there is high hazard exposure Vulnerability the man is very close, and soft and chewy he is highly vulnerable Tolerability he actually wants to be there he appears willing to tolerate the hazard, even though he is vulnerable Source: davefurness.co.uk Is this an intolerable, tolerable or acceptable risk for this man?

12 Land Use & Regulatory Tracks for Flood High risk Generally Intolerable Land use strategy: Retreat from specific urban areas Transition Strategy: Actively limit future development Scheme response: back zone to limited development Medium risk Tolerable Land use strategy: Adapt existing areas Transition Strategy: Discourage sensitive uses but permit most uses so as to not sterilise land Scheme response: Use flood constrained precincts in zones and overlays for built form controls Low risk Generally Acceptable Land use strategy: Adapt existing areas Transition Strategy: Implement built form improvements Scheme response: Few land use restrictions & overlays for built form controls

13 Process Planning Evaluation Results Identify the risk levels at a site based level Residential areas and airport are at intolerable risk of flood Source: QldRA, 2012 Mundubbera (North Burnett)

14 Process Comparison with Recent Event Intolerable risk identified in 2012, and severe damage during 2013 event Source: QRFS, 2013

15 Outcome Structure Plan derived from Risk Indicative structure plan is produced by using planning evaluation outcomes to guide land use response Land use response - back zoning of residential area to open space Relocation of properties to higher ground Avoid isolation - new access routes Source: QldRA, 2012 Mundubbera (North Burnett)

16 So how can risk improve the planning system?

17 Let s view planning issues as land use risks The risk of poor built form or reduced amenity The risk of environmental degradation The risk of economic loss or cost to the community Each of these risks can be identified through a Community Risk Profile a consultation and visioning tool And analysed through a Planning Evaluation Land Use and DA tracks can be developed based on the level of risk

18 If a development involves acceptable land use risk, why should we regulate and assess it? Why do we need to look at developments on a case by case basis when they might have common planning issues? Can a risk-based framework help identify real land use risks and perceived land use risks? Source: metricon.com.au Is dual-occupancy in a low density residential area risky development? Source: Bundaberg Regional Council What about properties destroyed by flood? Source: topnews.ae What about a commercial building in a city CBD?

20 Is it possible for land use strategy to be based on Risk?

21 Where are the gaps in your land use strategy? Does your land use strategy and scheme construction result in unnecessary regulation? Do we regulate some uses to harshly? Are we not harsh enough on others? Are you looking at interventionist planning programs like relocation, redevelopment or regeneration? Are you considering shifting to form based codes from traditional zoning/planning? Can your planning & assessment processes by improved by eplanning solutions? Risk Management doesn t need to mean Risk Conservative The key is determining the severity of land use risks in any given scenario, and building strategy out of the risk

22 I See A community deciding on its land use risks Quality land use strategy (whatever the purpose) developed on the basis of risk Regulatory tracks that are streamlined to those land use risks eplanning tools used throughout the planning process
