To address public health, staff began with creating an online Climate Risk Mapping tool to determine climate exposures at a neighborhood scale. Of the five vulnerabilities analyzed so far, extreme heat was identified as the biggest risk to Longmont. Efforts to address climate adaptation and public health have focused on extreme heat. See examples of actions taken in the Tasks section below.
The City's extreme heat efforts have been recognized by AT&T's Climate Resilience Cities program for additional technical support and funding to implement cooling in households most impacted by heat.
AT&T provided funding to the Longmont Community Foundation to support indoor cooling for households impacted by extreme heat. The City is working in partnership with the Community Foundation and community-based organizations that provide services and resources to heat-impacted residents to identify people that could best utilize this resource. Units will be available while funding lasts.
Sustainability, Parks, and Community and Neighborhood Resources are utilizing 2024 Sustainability Tax funds and ARPA funds to implement community-driven cooling solutions identified in 2023 in the Kensington, Lanyon, and Spangler community parks.
While the original goal was to assist 10-12 households, the program's outreach and impact exceeded expectations. A total of 24 single family households have received energy retrofits to date in 2025. This program demonstrates a strong demand and need for energy assistance. A large multifamily project is in the contracting phase and will provide efficient heating and cooling for 48 multifamily households by the end of 2025. These retrofits combine energy efficiency, housing rehabilitation and building electrification to enhance heat resilience while reducing greenhouse gas emissions and utility cost burden. This pilot program will continue through the end of 2025.
An initial staff training was conducted in June 2024, with additional support for implementation ongoing.
While the original goal was to assist 10-12 households, the program's outreach and impact exceeded expectations. A total of 24 single family, and 10 multifamily households received energy retrofits in 2024, demonstrating a strong demand and need for energy assistance. These retrofits combine energy efficiency, housing rehabilitation and building electrification to enhance heat resilience while reducing greenhouse gas emissions and utility cost burden. This pilot program will continue through the end of 2025.
The recommendations from the Heat Action Plan will be incorporated into the Longmont Indicators platform.














In 2025, Growing Shade will plant approximately 80 new trees on residential properties in Longmont’s Loomiller and Westpoint neighborhoods. Learn more on Boulder County's Growing Shade webpage.
