Bill overview

The Cool Corridors Act of 2025 reauthorizes and expands the Healthy Streets program to address extreme heat and improve transportation infrastructure. It aims to create ‘cool corridors’ – designated transportation routes enhanced with tree canopy, shade, and other nature-based cooling strategies. The bill focuses on promoting investments in these corridors, particularly in communities facing disproportionate heat and limited access, and strengthens the program’s focus on resilience, accessibility, and community engagement.

Key provisions

Extends the Healthy Streets program through 2030.
Defines ‘cool corridor’ as a transportation route enhanced with green infrastructure.
Expands eligible recipients to include transit agencies, state departments of transportation, and tree stewardship organizations.
Increases funding for projects focused on tree planting, shade infrastructure, and smart sensors.
Prioritizes investments in disadvantaged communities impacted by heat and low tree canopy coverage.
Requires plans for long-term maintenance and sustainability of cool corridors.
Mandates community engagement and workforce development activities.
Directs the Secretary of Transportation to coordinate with various federal agencies for technical assistance.

119th CONGRESS — 1st Session

H. R. 4420

IN THE HOUSE OF REPRESENTATIVES

A BILL

To reauthorize and amend the Healthy Streets program to enhance the resilience, accessibility, and safety of the Nation’s transportation corridors by supporting strategic investments in tree canopy, shade infrastructure, and other nature-based cooling strategies along pedestrian, bicycle, and transit routes.

1.Short title

This Act may be cited as the

Cool Corridors Act of 2025

2.Findings; purpose

(a)FindingsCongress finds the following:

(1)Extreme heat is a growing public health and infrastructure challenge.

(2)

Tree canopy and green infrastructure reduce surface and air temperatures, improve safety and usability along transportation corridors, and protect infrastructure from heat-related degradation.

(3)

Communities with limited infrastructure investment often lack sufficient tree cover and face increased exposure to extreme heat and limited transportation access.

(4)

Federal programs such as the Healthy Streets program and the Urban and Community Forestry Program have demonstrated both high demand and the effectiveness of locally driven, community-scale interventions.

(5)

Locally driven efforts to plant and maintain trees along key walking, biking, and transit corridors are under-resourced, despite proven benefits to heat mitigation, public safety, and community health.

(b)PurposeThe purpose of this Act is to—

(1)promote the deployment of cooling infrastructure along transportation corridors;

(2)

enhance resilience and safety of transportation systems in the face of extreme heat and improve air quality;

(3)

improve safety, accessibility, and usability for pedestrians, cyclists, and transit users;

(4)extend the useful life of infrastructure; and

(5)

prioritize investment in communities facing disproportionate heat and access challenges.

3.Reauthorization of Healthy Streets program

Section 11101(b)(2)(C) of the Infrastructure Investment and Jobs Act (23 U.S.C. 101 note(b)(2)(C)) is amended by striking through 2026 and inserting through 2030.

4.Healthy Streets program

(a)In generalSection 11406 of the Infrastructure Investment and Jobs Act (23 U.S.C. 101 note) is amended—

(1)

in subsection (a)—

(A)

in paragraph (2)—

(i)

in subparagraph (D) by striking and at the end;

(ii)

in subparagraph (E) by striking the period and inserting a semicolon; and

(iii)

by adding at the end the following:

(F)State and local transit agencies;

(G)

State departments of transportation;

(H)

local educational agencies; and

(I)

tree and greenspace stewardship organizations, environmental asset management groups, or infrastructure resilience partners with experience in protecting and sustaining green infrastructure and shade assets.

; and

(B)

by adding at the end the following:

(8)Cool corridor

The term cool corridor means—

(A)

a designated transportation route enhanced through linear greening strategies, including tree canopy, shade infrastructure, and other nature-based solutions designed to reduce surface and ambient temperatures; and

(B)

incorporates planning and stewardship measures to ensure the long-term functionality, protection, and climate resilience of the activities described in subparagraph (A).

(9)Heat mitigation strategies

The term heat mitigation strategies means activities that result in the mitigation of heat in public spaces, including tree planting, vegetative infrastructure, cool or reflective surfaces, shade structures, and other evidence-based practices, including the maintenance and preservation of already existing green infrastructure, roadside vegetations and trees.

;

(2)

in subsection (b)—

(A)

by inserting for demonstration projects in geographically and climatically diverse regions, including both urban and rural communities with historically low tree canopy or high heat vulnerability before to eligible entities;

(B)

in paragraph (1) by striking and at the end;

(C)

in paragraph (2) by striking the period and inserting , including the integration of shade structures, bus stop shelters, and climate-resilient streetscape elements, which may include the strategic planting of trees for shade;; and

(D)

by adding at the end the following:

(3)to plan, design, construction, and maintain tree canopy and green infrastructure along public transportation corridors, including alongside transportation right of ways, at bus stops, near transit hubs, and within designated public-school zones and properties;

(4)

to deploy smart sensors and data tools to monitor heat exposure and performance;

(5)

for community engagement, planning, and workforce development activities relating to heat mitigation, tree planting and maintenance; and
