Representative James R. Walkinshaw introduces H.R. 10839: Heat Island Reduction Act

We have received text from H.R. 10839: Heat Island Reduction Act. This bill was received on 2026-10-15, and currently has 2 cosponsors.

Here is a short summary of the bill:

This bill would require federal agencies to create plans for reducing the “heat island” effect at certain federal properties and facilities. The heat island effect is when paved and built-up areas absorb and hold heat, making those places hotter than nearby areas and sometimes contributing to worse air quality.

What properties would be covered

The bill would apply only to federal properties and facilities that are:

• controlled by a federal agency, and
• located in areas that are not meeting federal ozone air quality standards.

What the agencies would have to do

Within 6 months of the bill becoming law, each affected agency would have to prepare a heat island reduction plan. That plan would need to:

• identify the federal sites covered;
• assess ways to reduce surface heat, air temperature, building cooling demand, and pedestrian heat exposure;
• look for opportunities to add trees and other vegetation;
• increase shade over pavement, walkways, parking lots, and buildings;
• consider cool roofs, vegetated roofs, and other roof systems that absorb less heat;
• consider cool or permeable paving materials;
• use green infrastructure and other measures that may also help with stormwater, energy efficiency, or related goals;
• consider third-party certifications such as LEED or SITES if they help show the measures are being used;
• use other cost-effective heat-reduction practices.

What factors agencies would have to consider

When choosing measures, agencies would need to take into account things like local climate, existing vegetation, surface materials, pedestrian exposure to heat, water availability, maintenance needs, how long the measure is likely to last, whether it can be combined with planned maintenance or construction, and any possible negative side effects.

Implementation plans and updates

After making the reduction plan, each agency would have 180 days to submit an implementation plan to the General Services Administration (GSA). That plan would need to spell out:

• what actions the agency plans to take;
• where they will happen;
• milestones and timelines;
• which office will be responsible;
• estimated costs;
• funding sources;
• chances to do the work during scheduled maintenance or capital projects;
• any needed authority, help, or resources.

Agencies would then have to update these implementation plans at least every 2 years.

How the bill would be carried out and tracked

Agencies would be expected to carry out the plans using cost-effective measures, but only to the extent funds are available and other laws allow. GSA would have to submit annual reports to congressional committees describing how agencies are doing, including how many plans have been made, what sites are covered, what measures are being used, estimated costs, progress toward milestones, any measured or estimated temperature or energy-use reductions, common barriers, and recommendations for improvement. GSA could also give agencies technical assistance and share best practices.

Limits on the requirement

The bill would not force an agency to use a particular measure if it is not appropriate for the site’s climate, design, use, safety needs, historic character, security requirements, or other local conditions, or if it would not be cost-effective over its useful life.
