SECTION SIX Vulnerability Analysis
6.2.1 Asset Inventory
Asset inventory is the first step of a vulnerability analysis. Assets within each community that may be affected by hazard events include population (for community-wide hazards), residential and nonresidential buildings (where data are available), and critical facilities and infrastructure. Assets and insured values throughout the County are identified and discussed in detail below.
6.2.1.1 Population and Building Stock
Population data for Esmeralda County were obtained from the 2010 U.S. Census. Estimated numbers and replacement values for residential, nonresidential, commercial, industrial, and agricultural building, as shown in Table 6-1, were obtained from the County and HAZUS-MH by census block. A total of 627 residential buildings were considered in this analysis, including single-family dwellings, mobile homes, multi-family dwellings, temporary lodgings, institutional dormitory facilities, and care facilities.
A total of 39 nonresidential buildings were analyzed, including retail trade, wholesale trade, personal and repair services, professional and technical services, banks, medical offices, religious centers, entertainment and recreational facilities, theaters, and parking facilities. The HAZUS-MH software presents a data limitation, as this software identifies nonresidential

buildings by square footage resulting in some non-residential buildings not being counted. The actual number and value at risk could be higher if some nonresidential buildings are not being counted. However, in previous applications the HAZUS-MH software has accurately captured the total value of nonresidential buildings even though the building count is lacking. Although the building count may not be precise, this analysis meets the intention of DMA 2000 by providing Esmeralda County with an accurate visual representation of their community’s risk by hazard. These data are the most complete data set available at the time of this plan and will be updated in future versions of the LHMP.
In addition, there are two historically designated places in Esmeralda County which are considered vulnerable to hazard impacts, the Goldfield Historic District and the Goldfield Hotel. The NBMG has completed an inventory of unreinforced masonry (URM) buildings statewide. There are 24 URM buildings in Esmeralda County.

Esmeralda County.
6.2.1.2 Repetitive Loss Properties
Esmeralda County does not currently participate in the NFIP and is therefore not eligible to participate in the insurance program.
The State is required to identify strategies that encourage local communities to mitigate severe repetitive loss properties, including the development of local mitigation plans. At a minimum, the State must include severe repetitive loss in the description of its process for providing funding and technical assistance to prepare mitigation plans (§201.4(c)(4)(i)), and in its criteria for prioritizing communities that have such properties for planning and project grant assistance (§201.4(c)(4)(iii)). Other strategies for encouraging local communities to mitigate severe repetitive loss properties should be demonstrated through specific actions identified in the Mitigation Strategy (Chapter 8).

functions. During the LHMP update, the critical facilities and infrastructure inventory and cost estimates were updated. Critical facilities and infrastructure included in the LHMP are shown in Figure 7 (Appendix B) and include the following:

6.2.1.4 Future Critical Facilities and Infrastructure
Esmeralda County’s Master Plan was updated in 2011. Private land available for development is limited due to extensive Federal land management within the County. Future growth, if any, should be limited by the amount of water available. Future infrastructure and other development may be more vulnerable to impacts from hazards such as earthquake, wildfire, or flooding depending on the location of future facilities.
Since the 2010 update, there have been several new construction projects in the County. These include the expansion to the Goldfield Fire Station, the Community Center in Fish Valley, and the Welcome Center in Goldfield. These projects were inspected by the State Fire Marshall for building code compliance and incorporated appropriate mitigation measures, and therefore do not pose a significant vulnerability.
The Nevada State Demographer projects population increase from 2015 to 2019 (ranging from 1.5% to 5.1%) based on the on the 2014 estimate. No major facility or infrastructure projects are planned in the County at this time.
