Earth Week 2025
Join King County Department of Natural Resources and Parks as we celebrate the 55th Anniversary of Earth Day!

Earth Day is a special moment for us. It’s an opportunity to thank our employees and partners who work year-round to protect and restore the natural environment for the people, fish, and wildlife of King County. It’s also a time to discover what actions we can all take action to promote a healthier, more resilient, more sustainable future.
Join us April 19-26 as we highlight simple ways to care for our environment, whether it’s volunteering, reducing waste, supporting the local food economy, choosing non-motorized transportation, removing noxious weeds, or enjoying our regional parks and trails.
Together, we can protect, preserve, and restore the natural spaces that connect us all.
Earth deserves more than a day
Earth Day is an opportunity to appreciate the spectacular natural environment that defines our region and to take action that promotes a healthier, more resilient, more sustainable future. Join each day during Earth Week as we celebrate progress we’re making with partners and share personal actions that all of us can take.

Protect floodplains for future generations

Spring and summer are great times for home projects, but if you live in a floodplain, permits are required before you make repairs, build, excavate, grade, or fill on your property. Floodplains are critical natural areas surrounding lakes, rivers, streams, and Puget Sound. Permits help ensure smart, safe building practices that protect people and property now and in the future.
Learn more about floodplain permits and how they help our communities stay safe.
Easy ways to keep our water clean and reduce flood risks
Taking care of the land around our rivers, lakes, and streams helps reduce flood risks and improves water quality. Healthy floodplains slow runoff, store floodwater, and provide habitat for fish and wildlife. Here are a few simple actions you can take:
- Never dump waste in storm drains.
- Properly dispose of litter and pet waste.
- Sweep sidewalks, driveways, and gutters to keep pollutants out of waterways.
Learn more about the benefits of natural floodplains and water conservation.
