Airport Layout Planning for WSDOT - Managed Airports

Review the draft Airport Layout Plans (ALP) and Narrative Reports for 14 of the 16 state-managed airports located throughout Washington state.

Review the draft Airport Layout Plans for the state-managed airports.

WSDOT owns seven airports, leases one and operates eight under conditional use permits. Fourteen state-managed airports do not have current ALPs, other supporting drawings, or technical evaluations that Aviation Division staff can use to manage, plan, maintain, develop and protect the airports. The need for basic planning tools for the group of WSDOT airports has been identified by the Aviation Division for several years.

Century West Engineering Corporation has been selected to prepare ALP drawings and technical reports for five priority airports as the first phase of a multi-year project to develop ALPs for all WSDOT-managed airports.

The primary outcomes for each airport include:

  • Infrastructure assessment
  • An assessment of existing facilities, land ownership, and land use
  • Define facility and maintenance needs for each airport
  • Develop a capital and maintenance cost summary with prioritized projects identified
  • Airport Layout Plan drawing
  • Airspace Plan drawing
  • Inner Approach and RPZ Plan drawing
  • Land Use Plan drawing
  • Exhibit A Property Plan drawing
  • Technical Report

For the purposes of evaluating FAA and WSDOT-Managed Airport standards, all analyses will be based on the following assumptions:

Critical/Design Aircraft:

  • Single Engine Piston Aircraft (Typ. Cessna 172, 206, Piper PA28)
  • Aircraft Approach Category A (speeds less than 91 knots)
  • Airplane Design Group I
  • Small Airplane (12,500 pounds or less)
  • Airport Reference Code (ARC) A-I (small) will be used to define appropriate design standards


WSDOT's Airport Aid Grant Program is funding 95 percent of the $150,000 ALP project for the first five priority airports. The WSDOT State-Managed Airport Operating Fund is contributing a five percent local match.

Project Goals

The ALPs will define the short-term and long-term needs of the airport through a comprehensive evaluation of airport conditions and FAA/WSDOT design standards. The ALP's will provide specific guidance on making necessary improvements to maintain safe, efficient and user-friendly airports.

Project Goals

  • Maintain an open public participation process.
  • 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

These State-Managed Airports are not included in the FAA's National Plan of Integrated Airport Systems (NPIAS) and therefore, are not eligible to receive FAA funding.

State Airport System

Woodland State Airport is classified under the States Classification system as a "Local Service" airport in the Washington Long-term Air Transportation (LATS) System Plan. The remaining 13 airports are classified as Rural Essential airports.

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.
