Hazard
Extreme Heat
A heat wave is a period of abnormally and uncomfortably hot and unusually humid weather, typically lasting two or more days with temperatures above the historical averages for a given area.
Relevant Options
Provide financial assistance for low-income residents to help with power bills, energy upgrades to homes and apartments and support services during extended periods of high temperature.
Work with local medical providers and hospitals to ensure that medical facilities are prepared to meet any increased demand because of hazardous events.
Prioritize urban heat island mitigation strategies in transportation corridors to reduce the impacts of extreme heat on roads (e.g., trees, green roofs for buildings in transportation corridors, painting
Evaluate landscape and stormwater codes for suitability with projected changes in temperature and precipitation. Include an evaluation of how effectively
Support early maintenance and care of trees by building relationships and trust with community members.
Work with utilities and community partners to develop a weatherization program for renters. Doing so will reduce heating and cooling bills, especially
Identify community partnerships that could provide drinking water in emergencies.
Partner with banks to increase household emergency savings accounts.
Minimize stress on the electrical grid
Incentivize private property owners to implement green infrastructure (GI) and stormwater best practices through a reduced stormwater fee incentive program, zoning or other mechanisms. Encourage GI installations
Encourage the breeding of livestock animals and adoption of crops that are better adapted to warmer temperatures and greater precipitation variability.
Complete an urban tree canopy analysis to determine the ability of parks, tree canopy and wind flow to cool surrounding areas.
Launch or expand combined solar and energy storage pilots to build power grid resilience during extreme weather.
Map urban temperatures to understand where residents might be most vulnerable to extreme urban heat.
Plant additional trees near government facilities to reduce heat islands and energy bills.
Create an urban forestry program or position to maintain and improve tree canopy.
Incentivize affordable housing to include natural cooling features. This design will minimize the need for air conditioning and energy use, reducing energy bills.
Develop a local funding mechanism (e.g., gas tax or tax increment financing) to provide dollars towards non-capacity transportation projects.
Develop outreach and resource programs that provide clothing and knowledge for homeless populations to deal with being outside in extreme cold, extreme heat and extreme weather events.
Build electricity grid resilience by increasing system capacity, increasing tension in lines to reduce sag and adding external coolers to transformers. Lines and transformers may overheat and trip off
