Therefore, the level of analysis should be commensurate <br />with the economic risks involved. On the bottom of the risk scale, encroachments <br />which have little or no risk associated with them can be designed using appropriate <br />hydraul ic procedures. High risk encroachments which cr'eate large econor.1ic <br />risks should be designed using the techniques described in this circular. The <br />process of determining which of these responses is appropriate is discussed in <br />this section. <br /> <br />The determination of whether or not to design by the LTCe process can be viewed <br />as a screening process (figure 2.1). f.ll encroachments are assessed by comparin~ <br />prel iminary data to thresholds for each of the categories shovm: lacks practicable <br />detour, hazard to peopl e, anr~ hazard to property. If one or more of the threshol d <br />values ar'e exceeded, the encroachment should be designed by the LTEC process. If <br />the threshold values are not exceeded, the encroachment can he designed using <br />traditional design methods. <br /> <br />All <br />Encroach ments <br /> <br /> <br />Ha~ard t <br />o Pro <br />'/Jetty <br /> <br />File Assessment Report <br />Design by Experience <br /> <br />Design <br />by <br />LTEC <br />Process <br /> <br />Figure 2.1 Design Risk Assessment <br /> <br />3 <br />
