Seattle's 2019 - 2023 CTR Strategic Plan

The Plan has been adopted.

Thank you to our stakeholder group who provided input during our strategic planning process in 2017-2018 as well as all those providing comments on our draft Plan in 2019. The Plan was adopted by City Council on July 30th, 2019. Read the Plan here. You can also refer to the Executive Summary for a short overview.

Strategic Plan Overview

Seattle's Commute Trip Reduction (CTR) program plays a crucial role in the city's effort to reduce congestion and provide mobility choices. The CTR program is a key transportation demand management effort toward mitigating the impacts of population and employment growth while facilitating a thriving business environment, diverse travel choices, and a reduction in transportation emissions. As the city grows, it is ever more important to use our transportation system efficiently - and to therefore continue to make reductions in the proportion of drive alone trips.

The 2019-2023 CTR Strategic Plan establishes the vision for the next era of Seattle's program. It builds upon recent program innovations to position Seattle and its employers for ongoing success. The plan sets program performance targets and identifies program priorities for the next five years. It also includes a full analysis of the progress we have made over the last few years, including both performance and program improvements. It contains our new metrics and means for strengthening the program and measuring our progress. 

The planning team's analysis indicated how the program should evolve by adapting to the changing city and its commuting patterns. This Plan includes both revised network geographies and new Drive Alone Rate (DAR) targets beginning in 2019. These are summarized below, and background on how these were determined is included in the plan document. You can also refer to the 2013-2018 Networks and Targets to view information about the previous program period.

The strategic plan also outlines a package of potential solutions to continue to deliver high-quality programming and meet the challenges Seattle's transportation network faces. The proposed strategies cover Performance Monitoring, Policy and Regulatory issues, Programming and Engagement, Administration and Funding, and Emerging Markets. The Plan includes information on the implementation, benefits, and requirements for each strategy.

Changes to Networks & Targets for 2019-2023

SDOT has been working to update CTR networks and targets to fit the ever-changing context of transportation and commuting in Seattle as we head into the next biennium and beyond. 

Updated Networks

As in previous years, the city has been divided into geographic areas, called networks, for the purposes of target setting. Each network is assigned a target Drive Alone Rate (DAR) that CTR-affected employers located within that network will work to achieve. With the development of this Plan, some networks were edited to give greater geographical accuracy and more granular context to different neighborhoods whose transportation context is changing in different ways and at differing paces.

Updated Targets

Within this Plan, new updated Drive Alone Rate (DAR) targets are established for future time horizons to support achievement of Seattle's overall mode split goals. Each area of the city is assigned a target that all CTR-affected employers within a given network will work to achieve. The achievement of all network targets together means that the city as a whole reaches its goal. The Plan's targets are modeled to meet the city's 2035 DAR target of 25%, established as the citywide all-trips goal by the Seattle 2035 Comprehensive Plan.

Network Area 2017/2018* 2019/2020 2023/2024 2035/2036
Elliott Corridor/Interbay 53.6% 52.0% 49.1% 42.4%
East Seattle 49.3% 48.7% 47.6% 45.3%
Fremont/Green Lake 48.1% 47.5% 46.2% 43.5%
Northgate 69.0% 65.5% 59.4% 46.9%
South Seattle 65.2% 63.5% 60.4% 53.4%
U District 31.0% 30.4% 29.2% 26.6%
Pioneer Square & Chinatown/International District 21.9% 21.4% 20.4% 18.1%
South Lake Union & Uptown 28.1% 26.8% 24.5% 19.7%
Belltown & Denny Triangle 21.1% 20.0% 18.0% 14.1%
Capitol Hill, Pike/Pine, & First Hill 43.5% 42.9% 41.6% 38.9%
Commercial Core 15.8% 15.6% 15.2% 14.4%
Citywide 31.5% 30.6% 28.8% 25.0%

Center City Neighborhoods and Targets

In addition to the CTR Strategic Plan and its DAR targets, the City and its partners have committed to a vision for Seattle's core through the One Center City initiative. Center City neighborhoods are a subset of the updated CTR networks, and the 2019-2023 CTR Strategic Plan provides a subset of future full-market DAR targets for these specific neighborhoods. See the final page of our Executive Summary or page 27 of the full Plan for more information on our targets for the Center City.
