The paper "Bushfire Protection" is a wonderful example of an article on design. This article examines how the plan for bushfire has been designed to conform to the requirements of the Bushfire Management Overlay (BMO). It illustrates the measures and directions in designing permit applicants, the referral authorities as well as the responsible authority. This design outline follows CFA’ s protocols as a referral authority under The Victoria’ s planning system and the Planning and Environment Act 1987. The provisions for this planning and BMO are governed by the department of planning and Community Development (DPCD). Background information The bushfires that happened on the 7th of February 2009 made 173 people lose their life, over 2000 homes were burnt and approximately 430,000 hectares of land damaged.
This loss triggered the establishment of the 2009 Victorian Bushfires Royal Commission (VBRC) in response to the damages caused as a result of the bushfires in most parts. The main objective of the establishment of the VBRC was to conduct a study of the events that happened in the disaster and to set up recommendation to prevent such disasters from happening in the future.
The VBRC carried out extensive research into the planning, sources of fire, response and the effects of the 2009 bushfires. It focused on gaining an understanding of what happened and how the dangers of such a disaster recurring may be minimized in the future. The need to prioritize the safety of human life over other policy aims was one of the major findings of the VBAC. The Planning Scheme Amendment VC83 gave out new provisions for bushfire planning. The subsequent changes to the planning system are planned to reflect the new priority and the shared obligations of fire agencies, governments, Individuals, communities in reducing the possibility of a disaster similar to that of February 2009 from recurring.
A number of recommendations were included in the final report for VBRC in relation to planning for bushfires to minimize such effects. Bushfire risk and house loss Bush behavior Having knowledge of the behavior bushfire and how it destroys houses is vital when designing and planning new development. The bushfire protection processes aim to minimize the effects of, radiant Heat, ember attack, and direct flame contact.
It is therefore vital to have a vast knowledge of the behavior of bushfires in order to efficiently implement the protection measures of bushfires as outlined in Clause 52.47 and 44.06 and of the planning scheme. There are three key factors that affect bushfire behavior. These are the topography, weather conditions such as wind and vegetation. Weather conditions are taken into account in the procedures that concern the defendable space. Vegetation and topography are assessed in regard to the Bushfire Site Assessment. Topography The slope or topography of a place affects the intensity and the rate of spread of fire.
As the slope increases the speed at which fire burns and intensity also increases. When a fire burns in an uphill, radiant heat, preheat the bush matter ahead of the fire by drying it and making it easier to burn. The general rule is that for every 10˚ of the slope, the fire doubles its speed and intensity. For instance, if a fire is traveling at 10km per hour on flat ground and it starts at 10˚ slope, it will double in Intensity and speed by burning up the hill at 20 km per hour.
It’ s known that fires Fires usually move slowly as the gradient decreases. The flames cover less fuel, and less radiant heat preheats the bush matter in front of the fire. For every 10˚ of a decreasing slope and the speed of fire is halved in this case.
