Using HAZUS software, a standardized loss estimation tool developed and used by FEMA, the ECMHMP estimates that there is a loss value of $2.1 million due to the 100-year flood in the Town of Aurora, approximately 0.1% of the total RCV. Approximately $520,000 of this would be residential building loss, $645,000 would be commercial building loss, and the remainder, about $893,000, would be all other building uses, including agricultural, industrial, religious, educational, and governmental. B. Infrastructure Damage According to the ECMHMP, “critical facilities” are typically defined as “facilities considered critical to the health and welfare of the population and that are especially important following a hazard…. critical facilities include essential facilities, transportation systems, lifeline utility systems, high-potential loss facilities, and hazardous material facilities.” Grouped in with these assets are also police stations, fire stations, emergency medical services, schools/colleges, senior facilities, and medical facilities. The ECMHMP identifies US Route 20A and various county roads as important transportation routes which run through the Town of Aurora. According to the ECMHMP, “roads that are blocked or damaged can isolate residents and can prevent access throughout the planning area to many service providers needing to get to vulnerable populations or to make repairs.” US Route 20A may be impacted by a 1% annual flood chance event. Damage to or blockage of critical infrastructure, namely roadways, railroads, and utilities, can and will have serious consequences for residents in the event of a flood. These events may cause loss of communication, energy, heating/cooling, access to food, water, or shelter, access to medical services or supplies, lack of security and safety, lack of means of evacuation if necessary, and possibly even exposure to hazardous materials. These assets are described collectively as “lifelines” in the ECMHMP. There are 95 critical facilities within the Town of Aurora and 81 lifelines (see Figure 1). Of these, 17 critical facilities (17.9% of total) and 17 lifelines (21.0% of total) are in the 1% annual chance flood areas. These 17 critical facilities, which are also listed as lifelines, are various unnamed bridges throughout the Town of Aurora. 2 These fall under the transportation category of lifelines. However, according to the ECMHMP, these critical facilities are not expected to face potential loss due to flooding. 2 Data provided by Tetra Tech, Inc., developer of the ECMHMP.
