Airport and Maritime Salmon-Safe Certification

Salmon-Safe is an independent 501(c)3 non-profit organization that conducts third party assessment and certification for land and water management within the urban realm. This initiative significantly advanced restoration efforts in urbanized watersheds by developing urban aquatic protection guidelines and a citizen education campaign throughout the Pacific Northwest. Salmon-Safe developed certification standards for infrastructure sites (e.g., airport, road, rail, water and wastewater, energy). These Infrastructure Certification Standards are applicable across a variety of urban development landscapes, ranging from high-level master planning processes to single-site infrastructure projects. While the standards are designed as a stand-alone program, they can also complement other leading certification standards (e.g., LEED), by certifying project activities that specifically address ecological function and the quality of habitat for fish, wildlife, and people.


In 2016, Seattle-Tacoma International Airport (Airport) received Salmon-Safe certification under the Industrial Standards. Airport staff have worked with Salmon-Safe on certification that Airport operations and stormwater/habitat management programs protect local streams, the Puget Sound, and their salmon populations. This certification validates the Airport’s efforts toward environmental sustainability and compliments the Airport’s Long Range Plan and Century Agenda strategies and objectives. The Airport is the largest Washington urban site to be reviewed for Salmon-Safe certification and was the first US major transportation facility receiving the award.

Key Airport initiatives supporting the standards include Low Impact Development techniques to avoid or reduce stormwater runoff , and conservation of potable water through rainwater capture and reuse, high efficiency fixtures, and recycling of water.  The standards also support ongoing programs in habitat protection and restoration, invasive weed and debris removal, and ecological projects such as Bee Pollinator Habitat, Queen Bee Breeding Program, and Community Planting Project.

Airport Salmon-Safe:

Port removed a culvert and road to connect upper and lower reaches of Miller Creek. This portion of the creek was restored with large woody debris, gravel, and plantings.

Maritime Parks

The Port’s Maritime parks were first certified by Salmon-Safe in 2008 and recertified in 2013 and 2019. The program encompasses five parks and 10 public shoreline access sites, which cover over 44 acres or nearly 3% of Maritime property. The conditions for ongoing certification are intended to enhance the ecological environment and improve salmon habitat. Pre-conditions that have been satisfied for the certification included:

  • Expand landscape management plan to reduce pesticides and define integrated pest management measures
  • Prepare and implement a fertilizer management plan
  • Prepare and implement a water conservation plan
  • Assess opportunities for stormwater treatment projects
  • Assess opportunities for shoreline and habitat restoration projects

In the last few years, the Port completed a number of habitat restoration projects under the Habitat program, and installed green stormwater infrastructure projects under the Port’s Marine Stormwater Utility.
