Deane's Children's Park Site Plan

Staff presented the Site Plan for Deane’s Children’s Park to the Parks & Recreation Commission at its February 5th meeting. The presentation included a summary of the planning process, the inclusive design principles that guided the design, the primary play zones and play surfacing strategy, parking improvements, and proposed phasing strategy. As part of this meeting, the Commission reviewed the Site Plan and moved to recommend it, as presented, to the City Council for adoption. The Commission also directed the Chair and Vice Chair to develop a hand-off memo, which will be reviewed and approved at their March 5, 2026 Regular Meeting.

Site Plan - Design Summary

The Site Plan presents a cohesive vision for a forest-inspired, inclusive play environment that welcomes children of all abilities, caregivers, and visitors of all ages. It integrates community input and thoughtful design strategies to create safe, engaging, and accessible spaces. Key features include a central “Forest Path” linking major play zones and amenities, visual landmarks for intuitive wayfinding, welcoming entrances, and a clear circulation system for both playground and Bike Skills Area users.

Play experiences are organized into connected zones that support a range of ages, abilities, and play styles. Younger children enjoy accessible forest-inspired trails, while the central play area offers inclusive swings, adaptive equipment, climbing features, and sensory-rich elements that encourage social interaction and imaginative play. Central gathering spaces include a picnic shelter, restroom, seating, and accessible pathways, while integrated berms and Bike Skills Area features enhance safety and sensory engagement. Cherished elements like Kenton’s Dragon are preserved, and natural materials, forest forms, and art features reinforce the park’s immersive, nature-based character. Overall, the Site Plan balances inclusivity, programming, safety, and environmental context, establishing a flexible framework for meaningful play, learning, and community connection.

Staff presented the preferred Site Plan for Deane’s Children’s Park to the Parks & Recreation Commission at its November 6, 2025, Regular Meeting. The preferred plan builds on the "Woodsy Wonders" concept as the primary framework for the park’s design. Key elements from "The Quest" concept have been retained, including the restroom and picnic shelter, reoriented to improve sightlines and functionality, as well as the sensory “bridge” pathway connecting to Kenton’s Dragon. The design incorporates Kenton’s Dragon into a broader treehouse adventure theme, featuring subtle dragon-inspired elements such as themed activity nodes and playful discoveries, including a dragon’s egg.

The presentation highlighted the inclusive design principles guiding the project, major play features, proposed parking improvements, and a preliminary phasing strategy. Commission discussion affirmed that the Preferred Site Plan reflects community input and is moving in the right direction.

Phase 1: Gathering Initial Input (April–May 2025)

From April to May 2025, the project team launched the first phase of community engagement to help shape the future of Deane’s Children’s Park. We connected with the community through an online survey, an in-person open house, project booths at local events (MIPA Circus and Leap for Green), and activities at four Mercer Island elementary schools.

This outreach helped us hear from families, children, and longtime park users about what they value most in the park today and their ideas for its future.

What we heard:

• Strong support for inclusive and accessible play features, including improved paths and restrooms.

• Desire to preserve the park’s natural, wooded character.

• Enthusiasm for keeping the park’s dragon legacy alive through imaginative design elements.

• Interest in a unified theme, with Treehouse Adventure and Fairytale Kingdom as top choices.

• High interest in active play features such as swings, climbers, spinners, and ziplines.

• Support for phased improvements, beginning with a new restroom facility, followed by a picnic shelter and access upgrades.

Phase 2: Refining the Design Concepts (July–August 2025)

During the second phase of engagement, we shared two draft design concepts—The Quest and Woodsy Wonders—developed in response to what we heard in Phase 1. Community members were invited to share feedback on the overall look, feel, and character of the concepts, as well as specific preferences for types of play equipment.

Outreach included an online survey through Let’s Talk, a discussion with the Friends of Dragon Park, and project booths at community events such as Summer Celebration, Mostly Music in the Park, National Night Out, and Pride in the Park.

What we heard:

• Broad support for Woodsy Wonders as the preferred concept, appreciated for its natural, forested setting.

• Desire to meaningfully integrate Kenton’s Dragon into the updated design.

• Continued enthusiasm for unstructured, imaginative play that fosters creativity and exploration.

• Emphasis on inclusive features for a range of ages and abilities, while preserving the park’s wooded feel.

• Climbing and sliding were the most desired play elements in larger structures, with support for elevated, open spaces that reflect the park’s character.
