STRUCTURl'.LLY ACCEPTABLE TREA':'HE)iTS The Working Group concurs w'i th the interim policy guideline that floor :evels for housing arato be a minimum of 350 mm above the level of the land liable to flooding. i) ii) It is difficult to define o~ces on buildings subject to i~~ers~o~, as resultant forces depend on ~any factors including:- a) building location, b) orientation, c) degree of i"~ersion and d) building design. In model studies of the Te~egraph Station buildi2gs, tl1e SnoT"ty r-fountains Engineering Corporation have ~ecorded flow velocities around buildi~gs approaching 7 metres per second. Each building in affected areas would neec to be engineeringly designed to withstand flood forces. To erect a ~orDal residence csi~g c~e suspended floor technique, it is esti~ated that the price of the average residence would be increased by one-third of current costs.
