Excess Urban Heat Mitigation Act of 2025

Bill Summary: Excess Urban Heat Mitigation Act of 2025 (HR 3703)

Overview

The Excess Urban Heat Mitigation Act of 2025 is a legislative proposal designed to combat the "urban heat island effect"—the phenomenon where manmade structures and lack of vegetation cause urban areas to be significantly hotter than surrounding rural areas. The bill focuses on protecting public health, reducing energy costs, and addressing environmental injustices, as underserved communities often suffer from higher temperatures and fewer cooling resources.

Main Purpose and Intent

The primary goal of the bill is to establish a federal grant program to fund projects that either mitigate the causes of urban heat or manage its impacts. The legislation explicitly recognizes that extreme heat disproportionately affects low-income communities and people of color, aiming to allocate resources toward "environmental justice" by prioritizing these vulnerable populations.

Key Provisions

1. The Urban Heat Mitigation and Management Grant Program

The bill authorizes the Secretary of Housing and Urban Development (HUD) to award grants to eligible entities, which include:
* State and local governments.
* Metropolitan planning organizations.
* Indian tribes and territorial governments.
* Nonprofit organizations and consortia of nonprofits.

2. Eligible Projects

Funding can be used for a wide array of "eligible projects," including:
* Green Infrastructure: Tree planting (prioritizing native and shade-producing species), green roofs, and community gardens.
* Cooling Infrastructure: Cool pavements, cool roofs, shade structures, and the creation of cooling centers (ideally powered by renewable energy).
* Planning & Education: Urban forestry master plans, tree canopy assessments, arboriculture training, and community outreach.

3. Funding and Allocation

• Budget: The bill authorizes $30 million per year for fiscal years 2026 through 2033.
• Equity Set-Aside: At least 75% of funds must be awarded to projects in "covered census tracts" (areas with poverty rates of at least 20% or areas historically designated as "hazardous" by the Home Owners’ Loan Corporation).
• Cost Sharing: The federal government will cover up to 80% of project costs, though the Secretary may waive this to 100% for entities demonstrating economic hardship.
• Technical Assistance: Up to 3% of appropriated funds may be used to help eligible entities apply for and implement grants.

Oversight and Implementation

• Oversight Board: The bill establishes an oversight board comprising representatives from the EPA, HHS, DOE, and USDA, as well as academic and nonprofit experts. This board will develop a rubric to evaluate the success of the projects.
• Application Requirements: Applicants must provide a "robust engagement plan" demonstrating how they will inclusively involve community stakeholders in the decision-making process.
• Timeline: The Secretary must issue guidance for grant applications within 180 days of the Act's enactment, and the program must be established within one year.

Who is Affected?

• Underserved Urban Residents: Specifically those in high-poverty census tracts who will benefit from increased canopy cover and cooling infrastructure.
• Local Governments & Nonprofits: Who gain access to federal funding for urban planning and climate resilience.
• Public Health Infrastructure: Expected to see a reduction in heat-related hospitalizations and emergency room visits.
