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.
While the original goal was to assist 10-12 households, the program's outreach and impact exceeded expectations. A total of 86 households have received energy retrofits to date in 2025, underscoring a strong demand for and need for energy assistance. This includes 38 single-family and 48 multifamily households that benefited from retrofit upgrades. These comprehensive retrofits integrate energy efficiency, housing rehabilitation, and building electrification to improve heat resilience while reducing greenhouse gas emissions and household utility cost burdens. The program will continue into 2026.
In 2025, the Growing Shade program - a partnership with PLAY Boulder, Boulder County and City of Longmont to plant approximately 80 new trees on residential properties in Longmont’s Loomiller and Westpoint neighborhoods. Learn more on Boulder County's Growing Shade webpage. The City will continue this partnership in 2026.
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.
An initial staff training was conducted in June 2024, with additional support for implementation ongoing.
The recommendations from the Heat Action Plan will be incorporated into the Longmont Indicators platform.
AT&T provided funding to the Longmont Community Foundation to support indoor cooling for households impacted by extreme heat. The City worked in partnership with the Community Foundation and community-based organizations that provide services and resources to heat-impacted residents to provide AC units to 52 households. Staff is evaluating budget to continue this program in 2026.















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.
