Wake County Hazard Mitigation Plan - Adopted 10-21-2024

SECTION 4: RISK ASSESSMENT

Table 4.24 – Consequence Analysis – Drought Category Consequences Public

Can cause anxiety or depression about economic losses, conflicts over water shortages, reduced incomes, fewer recreational activities, higher incidents of heat stroke, and fatality. Impacts to responders are unlikely. Exceptional drought conditions may impact the amount of water immediately available to respond to wildfires. Drought would have minimal impacts on continuity of operations due to the relatively long warning time that would allow for plans to be made to maintain continuity of operations. Drought has the potential to affect water supply for residential, commercial, institutional, industrial, and government-owned areas. Drought can reduce water supply in wells and reservoirs. Utilities may be forced to increase rates. Environmental impacts include strain on local plant and wildlife; increased probability of erosion and wildfire. Farmers may face crop losses or increased livestock costs. Businesses that depend on farming may experience secondary impacts. Extreme drought has the potential to impact local businesses in landscaping, recreation and tourism, and public utilities. When drought conditions persist with no relief, local or State governments must often institute water restrictions, which may impact public confidence.

HAZARD SUMMARY BY JURISDICTION The following table summarizes drought hazard risk by jurisdiction. Drought risk is uniform across the planning area. Warning time, duration, and spatial extent are inherent to the hazard and remain constant across jurisdictions. The majority of damages that result from drought are to crops and other agriculture- related activities as well as water-dependent recreation industries. The magnitude of the impacts is typically greater in unincorporated areas, however Wake County is highly developed. In developed areas, the magnitude of drought is less severe, with lawns and local gardens affected and potential impacts on local water supplies during severe, prolonged drought.
