Parks, Recreation, and Open Space (PROS) Plan

The City of Mercer Island Parks, Recreation & Open Space Plan, (PROS Plan), is an update to the 2014 Plan that builds on the previously completed planning work and incorporates the feedback from an extensive community engagement process conducted in 2020 and throughout 2021. This Plan creates a vision for an innovative, inclusive, and interconnected system of parks, trails, and open space that promotes recreation, health, environmental conservation, and fiscal responsibility as integral elements of a thriving, livable Mercer Island.

The PROS Plan serves as a blueprint for the growth, enhancement, and management of the City of Mercer Island parks and recreation system and assists in guiding decisions related to planning, acquiring, developing, and maintaining parks, open space, trails, and recreational facilities. This plan also identifies priorities for recreation programs, special events, and arts and cultural activities.

The 2021 PROS Plan provides updated system inventories, demographic conditions, needs analyses, and a comprehensive capital project list. The Plan identifies parks and recreation goals and establishes a long-range capital plan for the Mercer Island parks and recreation system, including action items and strategies for implementation over the next six to 10 years. The recommendations in this Plan are based on community input, evaluations of the existing park system, operating conditions, and fiscal considerations.
