City of Irvine
2020 Local Hazard Mitigation Plan
U.S. for a four-person family is approximately an income of $26,200 or less. For Orange County, the FY 2020 Low-Income Limits for a four-person family, according to Housing and Urban Development (HUD), is $102,450. • Seniors (individuals at least 65 years of age): Seniors are more likely to have reduced mobility, physical and/or mental disabilities, and lower-income levels, all of which may decrease their ability to prepare for and mitigate a hazard event.
Table 4-2 shows the amounts of people in Irvine who meet at least one of the criteria for threatened, vulnerable populations. For more detailed demographic information, please refer to Chapter 2 .

The social threat analysis also shows the threat other populations may encounter, such as persons experiencing homelessness or persons without access to lifelines (vehicles or communication networks). Since data for these groups are not readily available, there is no definitive way to determine the amount of these persons in areas of elevated risk, so this assessment will discuss how these other threatened groups may also be affected on a general level.
Data Limitations and Notes on Vulnerability Tables
Due to data limitations, the data comparing the hazard zone population with the Citywide population comes from two separate sources. The Citywide data comes from the US Census Bureau’s American Community Survey, and the hazard zone population data comes from ESRI’s Business Analyst reports. As a result, there may be minor discrepancies in comparing the two data sets. The data that should be considered correct for this plan is the ACS data reported in Chapter 2. 122, 123,124

In addition to the City’s designated inventory of CFs/FOC and vulnerable populations, hazard events could threaten other assets that are important to Irvine. These assets may include services, artistic or cultural landmarks, or local economic activities. The threat assessment describes the potential harm to these other assets based on available information.
