<br /> <br /> <br />and other components, Port facilities - an integral part nf nur <br />nation's transpnrtatinn network - is also a "functional system" <br />of components: cargo handling equipment, piers, paved aprons, <br />railroad tenninals, conveyors, pipelines, and support senices, <br />Furthermore, if one component of the system is damaged and <br />unahle to function (e.g" transformer, substation, distribution <br />lines, etc.), then the entire system may be unable to effeclively <br />function, <br /> <br />Much of the damage to infrastructure and critical facilities from <br />Hurricane l'loyd took place in areas where the flooding <br />exceeded the IOO-year flood level. Wastewater trealment plants, <br />and electric and water utilities were suhmerged, while roads <br />and bridge foundations were scoured by flood waters, In some <br />instances, critical facilities sustained flood damage, <br /> <br />Indicators of Sustainable Infr.lstructure <br />and Critical Facilities <br /> <br />To be sustaillable, critical facilities and infrastructure must be <br />ahle to fuuction ~ectivcly, particularly when the senice (e,g" <br />hospitai, availability of electric power) supports life safety <br />functions. The indicators for critical facilities and infrastruc- <br />ture are designed to mC'Jsure progress in: 1) the siting of <br />facililies and syslems in areas that are nol susceptible to the effects of natural hazards; and 2) impro;ing dIe <br />performance (functionality) of dlese key senices during a disaster, Indicalors include: <br /> <br />Figure 1.5 <br />Elevated utilities for <br />this small husilless <br />were an important <br />factor in business <br />coutiuuityfollowiug <br />Hurricane F/{))'d. <br /> <br />. number of critical facilities and square footage - including hospitals, emergency <br />operations centers, police and fire stations, and schools - thal are located in areas that <br />are ha1~rd-prone <br /> <br />. number of repetitively damaged crilical facilities <br /> <br />. number of infrastructure elements - water supply, roads, bridges, sewerage, telecom. <br />munications, and port facilities - that are located in arC'JS that are ha1~rd-prone <br /> <br />. number of repetitively damaged infrastructure elements <br /> <br />. number of infrastructure elements that use design and construction techniques that <br />strengthen indi\idual components of the S)~tem against the forces of \\ind, water, and <br />groundshaking <br /> <br />. increase/decrease in the functionality of critical facilities and infrastructure systems <br />following a major disaster <br /> <br />Stnltegies 10 Promote Sustainable Infrastructure and Critical Facilities <br /> <br />Miligation strategies for infrastructnre, and to a lesser extent critical facilities, should reflect the interdepen. <br />dencies of each element of the system (e,g" water supply is dependent on availahility of electric power), <br />StrAtegies include: <br /> <br />. to promote desigll alld cOllstrtu;tioll practices for new, replaced, or repaired <br />infrastructure elements and critical facilities that wili improve their perfomlance and <br />functionality when c.xposed to the effecl' of nalural hazards, including hurricanes, <br />flooding, and C'Jrthquakes <br /> <br />16 <br /> <br />
