There have been a number c~ de~ailed s~udies of residential damage in Australia to esta-t:",:.sh such curves. Most of these have assessed p~ten~~al damage, few are based on surveys of actual dalnage f)llow~ng a flood event. The potential damage estimates are :;sual~::.: based on composite information from average contents ~~ven~~ries and their susceptibility co flood loss. A more d:ffic~lt problem is to assess building (structure) damage. :RES, in concert 'Nith the fir!TI Environmental Manage~ent, ~ndertook a detailed study of the damage from t~e 3;iney floods of August 1986. Th.ls was on behalf of che De9ar:~eDt of Public Works and Water ~esources Commission o~ N3~. :: included a very detailed survey of 70 residential D -n~p--ies -hat ~ad evperl.pnced "ve-f1onr ~lona"nq +-' ..... t-'--_ ...... '-J.~ ~.I. .0. __ l V ____ J.. V .... l __ P=ofessional loss adjustors were employed to assess, for each ~~ogerty, the damage to individual items in all flooded r~oms. The residents undertook a limited range of ac~ivi~ies to reduce contents damage but, as wich Alice Springs. there was no official flood warning and only a s:c.all proportion of residents had prior flood experience. 3uilci':":--;.g damage !.'las also assessed and, in most cases, was based JPon builders estimates. The estimates for both ccnten~s and building damage were divided into three groups "hich oorresponded to poor, medium and good qualit.y p~oper=y. The details are given in Tables A.I.I and A.l.2. 7he Sydney data for actual damage are considered to be tje besc currently available in Australia. The Alice Springs residential stage-damage curves, presented in Figure 2.2 and Table 2.2. are based on this information. The first s=ep has to average the results for the medium and good quality stage-damage curves from the Sydney study. This was c~nsidered to provide the best match to "he Alice Springs property. This value of this single curve was then i~creased by 25%. This was to allow for increased costs s~nce late 1986. taken as 10%, with a further 15% as a l~ading for the higher price of some goods and services in A:ice Springs_ The latter followed discussions with a number of persons including representatives of the Bureau of S:atiscics. It should be noted however, that the Bureau dees ~o: collect or publish specific information that compares Alice Springs prices to those for Darwin or for the other scate capitals. ~he stage-damage curves used in the original Alice Sprins.=s flood study, undertaken by PATtJA in 1986, em9loyed very much higher values for building damage than those recorr.:r-.ended in this study. Extensive surveys of residential bu~ld:~g damage following floods are sparse. The Sydney s~udYI in addition to the detailed study for 70 residential p~ope~=ies. had available estimates of building damage for 600 p~operties that experi~nced overfloor damage. These
