R. 10839 To reduce the heat island effect and associated ground level ozone pollution from Federal facilities, and for other purposes. _______________________________________________________________________ IN THE HOUSE OF REPRESENTATIVES October 15, 2026 Mr. Walkinshaw (for himself, Mr. Tonko, and Ms. Norton) introduced the following bill; which was referred to the Committee on Oversight and Government Reform _______________________________________________________________________ A BILL To reduce the heat island effect and associated ground level ozone pollution from Federal facilities, and for other purposes. Be it enacted by the Senate and House of Representatives of the United States of America in Congress assembled, SECTION 1. SHORT TITLE. This Act may be cited as the ``Heat Island Reduction Act''. SEC. 2. HEAT ISLAND REDUCTION PLANS FOR FEDERAL PROPERTIES AND FACILITIES. (a) Heat Island Reduction Plans.-- (1) In general.--Not later than 6 months after the date of the enactment of this section, the head of each agency shall develop a heat island reduction plan that covers each Federal property and facility that is-- (A) under the possession or control of the agency; and (B) located in an area designated under section 107(d) of the Clean Air Act (42 U.S.C. 7407(d)) as nonattainment with respect to a national ambient air quality standard for ozone. (2) Contents.--Each heat island reduction plan developed pursuant to paragraph (1) shall include the following: (A) An identification of each Federal property and facility covered by the plan. (B) An assessment of appropriate measures to reduce surface temperatures, ambient air temperatures, building cooling demand, or pedestrian heat exposure at each such property or facility. (C) An identification of opportunities, as appropriate for the property or facility, to do the following: (i) Increase tree canopy and other vegetation, including through species and planting locations appropriate for local climate and site conditions. (ii) Increase shade over paved areas, pedestrian areas, parking areas, and building surfaces. (iii) Install cool roofs, vegetated roofs, or other roofing systems designed to reduce heat absorption or building cooling demand. (iv) Use cool, permeable, or other paving materials or techniques that reduce heat absorption or promote evaporative cooling, where appropriate. (v) Incorporate green infrastructure or other measures that provide heat reduction, stormwater management, energy efficiency, or related benefits. (vi) Pursue third-party certification, such as Leadership in Energy and Environmental Design (known as LEED) or the Sustainable SITES Initiative (known as SITES), where such a certification would support or demonstrate implementation of heat island mitigation measures at the property or facility. (vii) Use other cost-effective technologies or practices that reduce the heat island effect. (D) Consideration, in selecting measures under subparagraph (C), of the following: (i) Local climate conditions. (ii) Tree canopy and vegetation. (iii) Surface materials and land uses. (iv) Pedestrian heat exposure. (v) Water availability and maintenance requirements. (vi) The expected effectiveness and useful life of each measure. (vii) Opportunities to coordinate heat island mitigation measures with scheduled maintenance, repair, renovation, construction, or landscaping projects. (viii) Any potential adverse or unintended effects of a proposed measure. (E) An establishment of priorities among covered properties and facilities based on the expected benefits and feasibility of heat island mitigation measures. (b) Implementation Plans.-- (1) In general.--Not later than 180 days after developing a heat island reduction plan pursuant to subsection (a), the head of each agency shall develop and submit to the Administrator of General Services an implementation plan for carrying out such heat island reduction plan. (2) Contents.--Each implementation plan shall include the following: (A) Each action the agency plans to take to…

carry out the heat island reduction plan. (B) The Federal properties and facilities at which such actions are expected to be carried out. (C) Milestones and estimated timeframes for carrying out such actions. (D) The office or component of the agency responsible for carrying out such actions. (E) Estimated costs associated with carrying out such actions. (F) Available or anticipated sources of funding for such actions. (G) Opportunities to carry out such actions as part of scheduled maintenance, repair, renovation, construction, landscaping, or other capital projects. (H) Any barrier, additional authority, or resource the agency determines is necessary to carry out the heat island reduction plan. (3) Updates.--Each agency shall update the implementation plan required under paragraph (1) not less frequently than once every 2 years and submit each such updated plan to the Administrator. (c) Implementation.--In carrying out a heat island reduction plan under subsection (a), the head of an agency shall, subject to the availability of appropriations and other applicable law, prioritize cost-effective measures identified in the implementation plan developed pursuant to subsection (b). (d) GSA Annual Report.-- (1) In general.--Not later than 1 year after the deadline for submission of implementation plans under subsection (b), and annually thereafter, the Administrator of General Services shall submit to the Committee on Oversight and Government Reform of the House of Representatives and the Committee on Homeland Security and Governmental Affairs of the Senate a report that assesses the progress of agencies in carrying out this section. (2) Contents.--Each report submitted under paragraph (1) shall include the following: (A) The number of agencies that have developed heat island reduction plans pursuant to subsection (a). (B) The number of agencies that have submitted implementation plans pursuant to subsection (b). (C) The number and location of Federal properties and facilities covered by such plans. (D) A summary of the heat island mitigation measures agencies have implemented or plan to implement. (E) The progress of agencies toward milestones identified in such implementation plans. (F) To the extent practicable, information on estimated or measured reductions in surface temperature, ambient air temperature, building energy use, or other relevant measures of effectiveness. (G) Estimated expenditures associated with carrying out heat island reduction measures. (H) Common barriers identified by agencies to carrying out such measures. (I) Any recommendations of the Administrator for improving or accelerating implementation of heat island reduction measures at Federal properties and facilities. (e) Coordination.--The Administrator of General Services may provide technical assistance to agencies in developing and carrying out heat island reduction plans and implementation plans under this section, including by disseminating best practices and information regarding cost-effective heat island mitigation measures. (f) Rule of Construction.--Nothing in this section may be construed to require an agency to carry out a particular heat island mitigation measure if the head of the agency determines that the measure-- (1) is not appropriate for the climate, design, use, safety, historic character, security requirements, or other site-specific conditions of the property or facility; or (2) would not be cost-effective over the expected useful life of the measure. (g) Agency Defined.--In this section, the term ``agency'' has the meaning given that term in section 551 of title 5, United States Code. <all>
