WSDOT Updates Methow Airport Layout Plan


The Washington State Department of Transportation (WSDOT) Aviation is developing an updated Airport Layout Plan (ALP) and Narrative Report for the Methow Valley State Airport (S52), located in Winthrop, Washington. Methow’s previous ALP was completed in 1995.

WSDOT is conducting the project in cooperation with the Federal Aviation Administration (FAA), Seattle Airports District Office. The FAA is funding 95 percent of the $67,000 ALP project, and WSDOT is contributing a five percent local match.

Methow’s updated ALP will define the short-term and long-term needs of the airport through a comprehensive evaluation of airport conditions and FAA design standards. The ALP will provide specific guidance in making necessary improvements to maintain a safe and efficient airport that is economically, environmentally, and socially sustainable.

Project Goals

  • Maintain an open public participation process.
  • Provide an updated assessment of existing facilities and activity.
  • Forecast airport activity measures (based aircraft, aircraft operations, etc.) for the current 20-year planning period.
  • Examine previous ALP recommendations to meet the current and projected airport facility needs consistent with FAA design standards.
  • Determine current and future facility requirements for both demand-driven development and conformance with FAA design standards.
  • Update/prepare the airport layout plan, airspace plan, and land-use plan for the airport to reflect updated planning.
  • Develop an Airport Capital Improvement Program (ACIP) that will prioritize improvements and estimate project development costs and funding eligibility for the 20-year planning period.

National Airport System

Methow Valley State Airport is included in the National Plan of Integrated Airport Systems (NPIAS). Participation in the NPIAS is limited to public use airports that meet specific FAA activity criteria. NPIAS airports are eligible to use federal funding for improvements through FAA programs such as the current Airport Improvement Program (AIP). Currently, there are more than 3,300 NPIAS airports and more than 75 percent are general aviation airports, similar to Methow Valley State. Three other communities in Okanogan County have airports included in the NPIAS: Omak, Brewster, and Oroville. Airports such as Twisp Municipal and Okanogan Legion are not included in the NPIAS and therefore, are not eligible to receive FAA funding.

The FAA recognizes NPIAS airports as being vital to serving public needs of air transportation. In doing so, the FAA recognizes that access to the nation’s air transportation system is not limited to commercial air service. The FAA requires that all NPIAS airports periodically update their airport plans to maintain effective long-term planning. This project will enable WSDOT Aviation to meet the FAA’s requirement to maintain an up-to-date plan. 

State Airport System

Methow Valley State Airport is identified as a “Local Service” airport in the Washington Long-term Air Transportation (LATS) System Plan.

Public Involvement

The public involvement element of the planning process will provide opportunities for all interested individuals, organizations, or groups to participate in the project. WSDOT has formed a planning advisory committee (PAC), which will provide a local review and input into the planning process. The PAC will review and comment on draft work products and provide local knowledge and expertise to the planning process. Members of the PAC include:

  • Dave Sandoz – Town of Winthrop Building Official
  • Kurt Oakley – Winthrop Chamber of Commerce
  • Charlene Beam – Okanogan County Office of Planning & Development
  • John Button – North Cascades Smokejumper Base
  • Jeff Wilkens – Wenatchee Valley Transportation Council (North Central RTPO)

The ALP process includes several PAC meetings. All meetings are open to the public.
