Park Planning, Open Space, and Trails

This page provides guidance on parks, recreation, open space, and trails planning for local governments in Washington State under the Growth Management Act, including planning requirements, state funding eligibility, examples of local plans and programs, best practices, and funding opportunities and other resources.

It is part of MRSC’s series on the Growth Management Act (GMA).


Overview

Parks, trails, and open spaces in cities and counties provide public health benefits by offering spaces for activity, relaxation, and community interaction. These areas also promote environmental sustainability, supporting biodiversity, managing stormwater, and mitigating heat island effects. The National Recreation and Park’s Green Infrastructure in Parks (2017) guide highlights the importance of sustainable practices like native planting and stormwater management to create eco-friendly park systems. 

Equitable access to these spaces ensures that all community members, including people with disabilities, can enjoy the benefits of parks. Americans with Disabilities Act (ADA) standards make parks inclusive and accessible for all users. Safety is another key priority, ensuring that playgrounds and other recreational facilities are designed to minimize risk of injury.


Parks Planning Requirements and Guidelines

In Washington, although RCW 36.70A.070(8) states that cities and counties that are required or choose to fully plan under RCW 36.70A.040 of the Growth Management Act (GMA) must develop a parks and recreation element as part of their comprehensive plans, it is actually optional since funds have not been appropriated to pay for preparing them per RCW 36.70A.070(10).

For more information about comprehensive plan optional elements, see MRSC’s Comprehensive Planning page.

While the parks and recreation element is optional, jurisdictions planning under the GMA must follow guidelines that ensure adequate park space for growing populations in their capital facilities plan element. These plans must include Level of Service (LOS) standards, which determine the amount of park space needed relative to the community's size and demographic needs (RCW 36.70A.070(3)).

To be eligible for funding from the Washington State Recreation and Conservation Office (RCO), cities and counties must update their parks plans on a six-year cycle. GMA comprehensive plans are updated on a different cycle (every 10 years), so sometimes these cycles don’t sync up. In this case, local governments adopt two different parks plans: a parks element of the comprehensive plan and a more detailed parks plan that complies with the RCO’s planning guidelines.


Parks and Recreation Elements of Comprehensive Plans

The following is a high-level summary of the steps necessary for preparing a parks element of a comprehensive plan as noted by Commerce and WAC 365-196-440:

  1. Begin with a needs assessment and inventory of existing parks, setting Level of Service standards to ensure adequate park space.
  2. Define goals and policies focusing on accessibility, equity, and sustainability.
  3. Plan for funding through sources like grants, levies, and impact fees.
  4. Coordinate the parks plan with other elements, such as land use and transportation.
  5. Engage the community to gather input.
  6. Ensure regular updates to keep the plan aligned with growth and changing needs.

Examples of City and County Parks Plans

This section includes examples of parks and recreation elements from GMA comprehensive plans (see RCW 36.70A.070(8)), as well as stand-alone parks plans.

Below are some city examples:

Recreation Planning and Programs

Recreational programs encompass a range of activities that individuals engage in for enjoyment and relaxation. These programs include sports, arts and crafts, outdoor activities, and community events that provide mental and physical health benefits.

Below are some local government examples: 


Open Space Planning and Programs

Under the Growth Management Act, open space (as well as green space and community forests) is required to be addressed in comprehensive plans through the land use element (RCW 36.70A.070). Often, it is included in not only the land use element but also optional parks elements. Cities and counties are also required to identify open space corridors within and between urban growth areas (RCW 36.70A.160).

Open space planning coordinates with other comprehensive plan elements, including parks and recreation, land use, transportation, and environmental protection. These plans protect natural areas, agricultural lands, and environmentally sensitive areas. Open space plans (usually grouped together with parks and recreation elements in comprehensive plans) must be updated regularly to remain eligible for state funding from the Washington State Recreation and Conservation Office (RCO).

Cities and counties implement various open space programs to preserve and manage lands within their jurisdictions. These programs often provide property tax incentives for landowners who maintain their property in qualifying open space, agricultural, or forest uses (see chapter 84.34 RCW).

Conservation programs also often work in coordination with parks systems to create regional networks of protected lands. For more information, see the section on Rural Land Stewardship and Conservation Programs on MRSC’s Rural Land Use Regulation/Development page.

Trails Planning and Programs

Effective trails planning integrates with comprehensive plans to establish support for trail systems and help secure funding from the Rails to Trails Conservancy. Trails serve as both recreational amenities and transportation infrastructure, connecting neighborhoods, parks, schools, and other community destinations. This section includes selected programs and initiatives focused on trails planning, development, and maintenance.

  • Issaquah
    • Parks, Recreation, Trails, and Open Space Element (2024) –  This section of the comprehensive plan envisions trails as connective links that join parks, open spaces, residential areas, and natural features like creeks and forested hillsides into an integrated system called the "Green Necklace."
    • Parks System Plan (2024) – Included an extensive public engagement process which resulted four core values that influence system investments – connectivity, vibrancy, resiliency, and balance.
  • King County Parks: Trail Connections – Manages the development and maintenance of trails in King County’s parks, including multi-use, biking, and hiking trails.
  • Monroe Trails Master Plan -Establishes a framework for improving, growing, and maintaining Monroe’s network of trails over the next two decades.
  • Pierce County Parks: Regional Trails Plan – Aims to create, develop, and maintain an interconnected trail system within Pierce County, with opportunities for volunteer involvement in trail maintenance and construction.
