The risk results provided composite LOF <br />and COF scores and a ROF score for each asset. The assets in each group were then ranked <br />in order of their risk score. <br />Risk results are displayed in a variety of formats. The risk result matrix shown below in <br />Figure 5.2 is a typical example showing assets with common likelihood and consequence of <br />failure scores. Assets that fall in the red area are considered high risk assets. In the risk <br />analysis, the high risk category is related to the condition of all of the assets in the San Marcos <br />system and not an indication of any immediate failure potential. The high risk assets in the San <br />Marcos system are assigned the top priority for further evaluation or more routine monitoring <br />and inspection. Asset monitoring and inspection can be used to identify any needed repairs and <br />help forecast when a more comprehensive rehabilitation program may be required. The assets <br />in the yellow area are typically programmed for inspection and evaluation within the next ten <br />February 2016 Page 26 <br />
