Year in Review 2025 Part 2

The City added a new high-efficiency street sweeper to the fleet thanks to the Washington State Department of Ecology through its Stormwater Financial Assistance Program. This investment reflects Sammamish’s ongoing commitment to environmental protection and responsible infrastructure management because it runs on alternative diesel, which has less GHG emissions.

So far this year, Sammamish has exceeded our target for the percentages of single-family residential HVAC permits filed (alteration or addition) as heat pumps. In 2025, the Eastside Climate Partnership target was 65%. As of November, Sammamish was at 68% HVAC permits issued being heat pumps. People can receive rebates through Energy Smart Eastside.

The City hosted five drive-through recycling events this year in partnership with the City of Issaquah, giving residents a convenient way to recycle hard-to-dispose-of items like tires, scrap metal, and batteries. Together, we collected 4,960 carloads totaling 420,594 pounds—about 210 tons—of material diverted from the waste stream. That’s roughly the weight of 50 fully loaded school buses.

Thank you to our partners: City of Issaquah, Eastside Catholic School, WA State Department of Ecology, King County Solid Waste Division, King County Hazardous Waste Management Program, PaintCare, and E-Cycle Washington.
