Connect Sammamish - Our TMP

*TMP Status Note* please see our Newsfeed post on the current status of the TMP here.

Improving How You Get Around Town

The City is developing its first Transportation Master Plan (TMP) which will include both short- and long-range strategies leading to the development of a multimodal transportation system to help achieve the City’s transportation vision and goals over the next 20 years.

The TMP will provide a strategic framework and prioritized investments to help improve how we get around town. In doing so, there are several issues and needs to consider when deciding how and where to spend limited resources. These include:

  • Addressing the challenges of growth on the transportation network;
  • Promoting safety for all users;
  • Developing a long-term, sustainable financing plan;
  • Finding a way to achieve a connected road network while maintaining neighborhood character;
  • Integrating new technologies; and
  • Finding ways to partner with transit agencies, school districts, regional partners, and others to meet the community’s most pressing transportation-related needs.

Draft TMP Now Available!

The TMP Project Team has developed a draft TMP, which is the culmination of extensive community outreach, significant technical data collection and analyses, and City Council input beginning in spring 2017. The Draft TMP documents the community’s goals and priorities for the City’s transportation network. It addresses Sammamish's transportation challenges now and into the future by identifying issues and optimizing multimodal transportation investments in the City. City Council and community input on the Draft TMP will be reviewed and incorporated into a revised TMP, which will be the subject of a future online open house on this webpage in the tools below.

    Check out the City's first Draft TMP here and let us know what you think when we commence a virtual open house this summer! The virtual open house will occur after the TMP Project Team receives additional direction on the Prioritized Projects List (TMP Chapter 4) from the City Council at an upcoming Council meeting to be scheduled. City Council and community input on the Draft TMP will be reviewed and incorporated into a revised TMP for further consideration by the City Council prior to adoption.

  • TMP Statistically Valid Survey Results

    Share on Facebook Share on Twitter Share on Linkedin Email this link


    The TMP Survey is available for your review!

    The City of Sammamish Transportation Master Plan Survey (“TMP Survey”) gave residents an additional opportunity to provide their opinion about the transportation needs and priorities in Sammamish last fall. It complements the already robust outreach effort accomplished to date for the TMP. One of the key products of the TMP is a list of prioritized capital projects for the City’s transportation network. Input from the statistically representative sample of the community will be used to refine the prioritized projects list.

    To view the full TMP Survey Results, visit here!

    How was the Survey conducted?

    The TMP Survey was administered by mail to 3,000 randomly selected households within the City boundaries in October 2019. Of the approximately 2,938 households that received a survey in the mail (the other surveys were sent to vacant households), 687 surveys were completed, a response rate of 23%. Typical response rates to a broad resident survey of this type generally range from 12% to 30% so we were encouraged by the level of community engagement.

    Stay tuned to follow the progress of the TMP and development of the prioritized project list by signing up on Connect Sammamish.

  • TMP Input Tracker - UPDATED!

    Share on Facebook Share on Twitter Share on Linkedin Email this link

    Throughout our outreach efforts for the Transportation Master Plan (TMP), we’ve been recording all the input received from our in-person and online exercises. We first shared that data with you in late September. As community input continued via Connect Sammamish and other methods, the TMP Project Team has been updating the TMP Input Tracker, which you can now view here. This version of the TMP Input Tracker contains all input through November. Sharing this data is part of our desire to be transparent and to keep the conversation going in the community!

    Take a look and see how your favorite projects resonated with your neighbors.

    A Few Reminders

    The TMP Project Team has categorized all projects by project type (auto, pedestrian, connection, transit, bike), date, method and date of submission, and write-in projects. The projects we have included as City-Identified projects are a subset of a larger project list.

    These tallies will be used to help inform our Prioritized Project List that will be included in the Transportation Master Plan.

    More notes about how to review the spreadsheet are contained within the spreadsheet itself and also detailed in the previous NewsFeed post here.

    Throughout our outreach efforts for the Transportation Master Plan (TMP), we’ve been recording all the input received from our in-person and online exercises. Now, we’d like to share that data with the public in an effort to keep the conversation going in the community! Take a look and see how your favorite projects resonated with your neighbors.

    We have categorized all projects by project type (auto, pedestrian, connection, transit, bike), date, method and date of submission, and write-in projects. The projects we have included as City-Identified projects are a subset of a larger project list.

    How is the Community Input Used?

    These tallies will be used to help inform our Prioritized Project List that will be included in the Transportation Master Plan. The net vote that these projects receive will be given a score in a more comprehensive scoring system to help determine the Prioritized Project List.

    Some important things to note when reviewing this document:

    · The projects shown in the TMP workshop exercise are a subset of a much larger list.

    · In both the online and in-person exercise, attendees were free to write-in any project they felt was missing. The write-ins were categorized by the project station they were contributed at.

    · Write-In Projects were recorded as precisely as possible.

    · For the in-person workshops, attendees were given ten dots to show support for a project and one dot to show opposition to a project.

    · Attendees were free to vote more than once for the same project.

    · The “Workshop Project ID” category in the spreadsheet corresponds to the project numbers in the brochure passed out at the workshop and the “City Project ID” category is the number system the City uses to identify projects. Both systems are for identification purposes only.

    · Asterisks in the “Workshop Project ID” category mean that the project requires coordination with other municipalities to complete.

    · The total net vote was calculated by subtracting the total “No Tallies” from the total “Yes Tallies”. Every vote was worth a value of one; there was no weighting implemented.

    · The Connect Sammamish tallies were recorded on 9/6/19 and then updated on 9/19/19. The contributions after 9/19/19 will be updated once the online component closes on 11/7/19.

    We hope you enjoy exploring the data and seeing how your input contributed to the ranking of the projects so far. Also available for review are the comment cards we received- look for the tab at the bottom of the Excel document. Thank you again so much to those who came to our workshops or participated online, your thoughts count and matter to the development of the TMP. Please visit the online mapping tool if you still want to participate! We will be counting all online contributions after the tool closes on 11/7/19 to update the document.

  • We Partied With You at Party on the Plateau (P.O.P)!

    Share on Facebook Share on Twitter Share on Linkedin Email this link

    We were at the Party on the Plateau with you on Saturday and had some really great conversations about the ways that everyone gets around town! We learned about specific areas in the City, including intersections near schools and neighborhoods off of Issaquah-Fall City Road. Even more, we heard from lots of Sammamish kids about how THEY get around town. The kids had the chance to draw their favorite way to get around town with crayons, and they did not disappoint! These budding artists love to bike, ride scooters, walk, drive with their parents, and they even want to use hoverboards in the future.

    Keep the conversation going by coming out to our second of three identical workshops at Blackwell Elementary School on Thursday August 22!
