Draft CTR Strategic Plan for 2019-2023

What’s happening now?

Thank you to our stakeholder group who provided input during our strategic planning process in 2017-2018.

We accepted comments from stakeholders and the public on the Draft 2019-2023 CTR Strategic Plan prior to its adoption by City Council earlier in 2019. Presentation to council is planned for July 2019. Thank you to all stakeholders who provided comments.

If you have further questions about the CTR Strategic Plan, please send them to Sarah.Spicer@seattle.gov.

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 tool to mitigate the impacts of population and employment growth while facilitating a thriving business environment, diverse travel choices, and a reduction in transportation emissions.

The Draft 2019-2023 CTR Strategic Plan establishes a vision for the next era of Seattle's program. It builds upon recent program innovations to position Seattle and its employers for ongoing success. When adopted, this plan will set program performance goals and identify program priorities for the next five years. The draft plan 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. You can also refer to the Draft Executive Summary for a short overview.

The strategic plan analysis indicated how the program should evolve by adapting to the changing city and its commuting patterns. The Plan therefore includes both revised network geographies and new Drive Alone Rate (DAR) targets beginning in 2019. These are summarized below. For background on how these were determined, all the details are in our draft plan. 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 growing challenges Seattle's transportation network will face. The proposed strategies cover Performance Monitoring, Policy and Regulatory issues, Programming and Engagement, Administration and Funding, and Emerging Markets. Further information on the implementation, benefits, and requirements for each strategy are provided in the strategic plan.

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. 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.

Updated Networks

The City of Seattle has divided its territory into geographic areas, called networks, that are each assigned a specific Drive Alone Rate goal that CTR-affected employers located within that network will work to achieve. Some network boundaries were edited or subdivided 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

Each CTR network area is assigned a Drive Alone Rate target that all CTR-affected employers within a given network must work to meet. These targets set the maximum proportion of trips employees can take while driving their car or motorcycle alone. With this draft CTR Strategic Plan, new DAR targets are established for additional time horizons to support achievement of Seattle's overall mode split goals. Once again, the achievement of all network targets together means that the city as a whole also accomplishes its goal. The plan extends the horizon to the city's 2035 future DAR target of 25%, established as the citywide all-trips goal by the Seattle 2035 Comprehensive Plan.

Network Area 2017/2018* Draft 2019/2020 Draft 2023/2024 Draft 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%

* These DAR rates were not formal CTR targets in the prior plan. The 2017/2018 goals presented in the table above have been adjusted to account for redrawn network boundaries for the 2019/2023 Strategic Plan. The 2017/2018 figures are for presentation purposes only.

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 Draft 2019-2023 CTR Strategic Plan provides a separate accounting of future DAR targets for these neighborhoods. The targets are inclusive of all commute trips—deemed the "full market"—and not just those generated by CTR-affected employers. You can learn more by reviewing page 27 of the draft plan.
