Explore + Restore: Cedar River Natural Area

Save the Date!

Since our last community engagement, the project team has been building on community feedback, studying existing trails and natural areas, conducting environmental fieldwork, and refining a proposed trail network. Join us to learn what we’ve discovered, see what’s next, and help shape the details of the experience.

Join us for a Community Meeting

Renton Community Center
1715 Maple Valley Hwy, Renton

The project team will share the proposed trail network map and provide updates on:

• Trail and site investigations
• Environmental restoration and permitting
• Trail safety and maintenance considerations
• Progress toward construction

While the proposed trail network is being shaped by site conditions, environmental protections, safety, and long-term maintenance needs, there are still opportunities to help shape how people experience the Natural Area.

We want to hear your ideas about trail amenities for walkers, hikers, runners, and cyclists; features for a mountain bike skills area; programs and stewardship; implementation priorities; and ways to make the Natural Area more welcoming and accessible.

Project Update

The Cedar River Natural Area Trails and Forest Restoration project is getting ready for its next phase: moving the project forward from early ideas into more detailed design, and permitting.

In 2025, the project team completed site analysis and community engagement to better understand how the space is used today and what improvements matter most to the community. Please see the full Park Programming Analysis for more detail.

This early work confirmed that the area includes a mix of forested habitat, wetlands, streams, and steep slopes, along with some previously disturbed areas near the Cedar River Trail and dog park. From the community we heard the need to improve safety, protect the natural environment, expand walking and nature-based experiences, and thoughtfully add mountain biking opportunities. Many community members also expressed interest in better trail connections, basic amenities, and opportunities to stay involved over time.

Looking ahead, the project will explore a connected system of trails and features that support a range of recreation experiences while maintaining the natural character of the site. Design will also incorporate habitat features and restoration strategies to support local wildlife and long-term environmental health. The consultant team will continue refining concepts, completing environmental review and field studies, and preparing plans to support permitting and future construction.

Before this work can advance, the City Council will consider approval of funding for this next phase. The proposal will be reviewed by the Council Finance Committee and full Council on April 13, 2026.

Renton Parks is excited to share an early look at a new concept for the Cedar River Natural Area (CRNA) - a project that imagines this unique space as a place where community recreation and ecological restoration come together.

Recreate + Connect

The concept plan (PDF version here) envisions trail-based recreation, including mountain biking, hiking, and trail running, supported by key amenities like restrooms, parking, and gathering areas. A network of progressive trails will offer experiences for all skill levels, from beginner flow zones and skills areas to challenging hillside routes. Connector trails will link nearby neighborhoods and the Cedar River Trail for improved access and mobility.

Restore + Revitalize

Some areas of the CRNA are ready for forest and habitat restoration. Removing invasive species, planting native vegetation, and cleaning up debris will enhance biodiversity, protect stream health, and create a more vibrant, resilient natural landscape.

This early concept is the first step toward shaping the CRNA’s future. Come chat with the project team at our Engagement Events this week to learn more or provide your feedback through our online survey.
