Proposed Extension of Seneca Street

This website has been created by officers of several of the Citizen Involvement Organizations in the City of Tualatin to explain our members’ objections to the proposed extension of Seneca Street eastward from Martinazzi Avenue and into the redeveloped Kmart plaza, which will be known as Nyberg Rivers.  An illustration of the proposed extension can be seen to the right of this text, and the City’s explanation of the benefits of the project can be found here.  To be clear, the CIOs represented here strongly support the concept of the redevelopment of the Kmart plaza and the creation of new, family wage jobs.  The City is certain to benefit from another marquee development similar to Bridgeport Village and Nyberg Woods.  Our objection to the plan for the redevelopment is that the plan calls for the demolition of the current Council Building without a plan for relocating the services currently housed there, while spending an estimated $440,000 in City funds for an unneeded road that is not supported by the citizens of Tualatin and will negatively affect one our City’s great treasures, its Library.

The concept of extending Seneca Street over the rubble of the Council Building has twice been rejected by the public, most recently in November 2013. To learn more about the consistent, widespread public opposition to the Seneca extension, please visit the Public Opinion page.

The proposal to extend Seneca Street requires demolition of the Council Building and the splitting of the Library’s parking lot.   This proposal will reduce the already insufficient number of parking spots for Library patrons, and will also negatively affect safety and convenience of use for patrons of the Library.  To learn more about the negative effects to the Library resulting from the proposed extension of Seneca Street, please see the Effects to Library page.

Some suppose that if the extension of Seneca Street is to be built, it makes better sense financially to build it now, in conjunction with the development of Nyberg Rivers.  A complete analysis of all of the costs involved, however, indicates that the City would save very little money (less than $80,000 over 5 years) by constructing the extension of Seneca Street in the immediate future.  Of course, never building the Seneca extension would be the greatest cost saver, and would allow for the use of $440,000 in City funds for arguably more important transportation infrastructure projects.  To see the detailed cost analysis for current versus future construction, as well as other related items, click through to the Financial Impact page.

The developer and its traffic engineer have consistently stated that the extension of Seneca Street is not necessary for the proper development or expected traffic use of Nyberg Rivers.  Traffic engineers retained by the City have disagreed.  While the competing analyses of the traffic engineers are highly technical in nature, one basic point of agreement is that the existing infrastructure will continue to meet an acceptable standard for level of service after the Nyberg Rivers development is completed.  To learn more about the traffic analysis and the impact of Nyberg Rivers, please see the Traffic Impact page.

The Council will vote on whether to move ahead with the immediate extension of Seneca Street Seneca on Monday, January 13.  If, after reviewing the content of this site, you share our objections to the immediate extension of Seneca, then please use the link below and share this site via your Facebook or Twitter.  You can also email the City Council (council@ci.tualatin.or.us) with your comments.
