Executive Summary <br />Snoqualmie Pass (the Pass) is a small <br />mountain community located at the border <br />of Kittitas County and King County. Known <br />for its popularity as a year-round recreation <br />destination, the area experiences significant <br />seasonal and weekend traffic fluctuations <br />that impact quality of life and safety for <br />residents and visitors alike. <br />In response, Kittitas County is developing a Comprehensive <br />Safety Action Plan (CSAP) tailored to the unique conditions <br />of Snoqualmie Pass. This plan adopts the Safe System <br />Approach—an evidence-based framework that prioritizes <br />proactive and systemic strategies to eliminate traffic related <br />deaths and serious injuries. It also aligns with Vision Zero <br />principles and supports eligibility for federal funding through <br />the U.S. Department of Transportation (USDOT) Safe Streets <br />and Roads for All (SS4A) program. <br />CHAPTER 1: INTRODUCTION <br />Provides an overview of the <br />community’s demographics, <br />existing transportation challenges, <br />and prior safety-related plans <br />and initiatives, which lay the <br />foundation for this CSAP. <br />CHAPTER 2: ENGAGING THE COMMUNITY <br />Describes the three-phase <br />outreach process the project team <br />used to gather local insights, as <br />well as key themes and concerns, <br />that informed the development of <br />responsive solutions. <br />CHAPTER 3: ANALYZING DATA <br />Summarizes the CSAP’s robust <br />analysis and data-driven approach <br />to identify patterns and trends, <br />high-risk conditions, and <br />opportunities for proactive safety <br />improvements. <br />CHAPTER 4: IDENTIFYING COUNTERMEASURES <br />Identifies priority locations in <br />Snoqualmie Pass where targeted <br />safety improvements, both <br />engineering and non-engineering, <br />are recommended. <br />CHAPTER 5: IMPLEMENTING THE PLAN <br />Outlines strategies and actions <br />Kittitas County can take to <br />improve safety in Snoqualmie <br />Pass through an action plan, <br />implementation guidance, and <br />performance monitoring. <br />In this Plan <br />Teanaway <br />Community <br />Forest <br />Baker-Snoqualmie <br />National Forest Okanogan-Wenatchee <br />National Forest <br />KITTITAS COUNTY <br />Snoqualmie <br />Pass <br />90 <br />90 <br />90 <br />Source: Fehr & Peers, 2025; aerial <br />courtesy of Google Earth Pro. <br />Between 2014 and 2023, 107 collisions were <br />reported in the community, including three that <br />resulted in serious injuries or fatalities. <br />2014 2015 2016 2017 2018 2019 2020 2021 2022 2023 <br />13 9 7 11 14 8 12 11 7 12 <br />1 <br />1 <br />1 <br />Killed or Serious Injury <br />(KSI) Collisions <br />Three Collisions (3%) <br />5 Snoqualmie Pass Comprehensive Safety Plan | Kittitas County
