The City Engineer is responsible for: <br /> <br />1. ~n coordination with Colorado Geological Survey, collectioll and <br />cnalysls of data on potential debris floh threats (Emergency <br />?reparedness CoordInator Sllould be kept informed of significant <br />cnforelation) . <br /> <br />2. ~et:er;llining, and providing for in the annual budget, funds <br />required to support monitorIng and mitigation measures. <br /> <br />K. The County Assessor is responsj.ble for: <br /> <br />1. ?roviding information on damages sustained to Co~nty/City <br />Dopulatlon, public facilj.tles, utilities, high\"ays and other <br />i'esources. This assessment is to be used by all levels of <br />;overnment to assign prIorities for aSsIstance and 25 c. basis for <br />declaring a dlsaster or emergency (see Damage Assessment Anne:( of <br />this plan). <br /> <br />VIII.

Electronic warning devices that sense movement ana transmit <br />warnings are available and have proven successful in other areas <br />\,ith debris and earthflo~" problems; ho\..rever, they are expensive <br />and difficult to justify [rom a cost/benefit standpoint in the <br />short term. <br /> <br />2. In lieu o[ an electronic early h'arfling syste~, the best. indicator <br />of potential debris flol'ls is rainf811. The rainstom thzt set off <br />the debris flo"s of July, 1977 produced 1.08 inches of rain, 0,8') <br />inches of which came in only about a halt hour (the soil was wet, <br />although not saturated. prior to this StorCl) , Accord1ng to CGS, <br />it can be assumed that future rainstor~s of similar intensity and <br />durBtion would also trigger debris flows (although storms of <br />lesser illtensity - and greater probability - may also be capable <br />of producing serioLls debris flow events). <br /> <br />3, Public educatlon and awareness programs should address the <br />correlation of rainfall to debris flows, home emergency protectIve <br />measures that can be taken when threatening rainstorms occur anrl <br />other debris flow mitigation steps that property o"ners can employ <br />
