    The City has coordinated with Sound Transit's East Link outreach staff to offer office hours every other Tuesday (11:00am-1:00pm), starting July 12 through at least the end of 2022. Look for ST staff in the lobby of the community center (MICEC, 8236 SE 24th Street) where they will host an outreach table, offer flyers and materials, and answer general questions about light rail and the construction of the transit interchange (i.e the roundabout and other features).

    In order to safely construct the roundabout at North Mercer Way and 77th Ave SE, Sound Transit has implemented several trail detours that will be in place untll approximately the end of 2022.Various portions of the Mountains-to-Sound (aka I-90 Trail) and some neighboring sidewalks are closed to all users. Click here to view detour map. The green lines in the detour map are the suggested alternative routes; note that the dotted green route connects but does not have sidewalks. Detour routes are signed at key intersections and locations.

    Sound Transit contractors have begun work on one of the last major components of the Mercer Island Transit Interchange necessary for rail to open: a new roundabout located at 77th Ave NE and North Mercer Way. Earlier this spring, the houses adjacent to the roadway were removed to prepare the area for a new stormwater vault (installed in early May), roundabout construction, and a stretch of new sidewalk and landscaping. Work on the roundabout is expected to be complete in late 2022; the two images in this update are Sound Transit visualizations. (click here for larger images)

    The roundabout will serve as the turnaround for buses after westbound riders are dropped off at the existing bus stop on North Mercer Way. Buses will then circle the roundabout and travel back eastward to pick up riders at the existing bus stop on the south side of North Mercer Way.

    Residents should be aware that the westbound right lane and northside sidewalk will be closed until fall of 2022 to accommodate this work. Please be aware of workers along the road, avoid construction areas, and follow detour routes.

  • An Update on the City’s Motion for Discretionary Review

    This afternoon, the Commissioner for the Court of Appeals issued a ruling denying the City’s motion for discretionary review of the Superior Court’s decision granting Sound Transit’s motion for summary judgment. Although the ruling is disappointing, the City is evaluating its options and preparing for the next phase in its litigation with Sound Transit.

    After the King County Superior Court’s decision granting partial summary on December 17, 2021, the City has filed a motion with the Washington State Court of Appeals seeking permission to pursue an early appeal of that decision, rather than waiting until after trial on the portion of the case that still remains to be resolved. The City’s motion to the Court of Appeals is fully briefed and those briefs are available here. On April 15, 2022, the Court of Appeals will hear argument on the City’s motion. If the City is successful, the City’s appeal will then go forward before the Court of Appeals. If the City is unsuccessful, then the parties will proceed to trial.

    The King County Superior Court also granted the City’s request to re-set the trial date (previously to begin in March 2022) to February 2023. This new trial date will allow time for the Court of Appeals to hear and resolve the City’s motion and time for appropriate discovery in the event the City’s motion is denied and the case proceeds to trial.

    Additionally, the City sought and was granted a voluntary dismissal of its appeal of the LUPA decision before the Court of Appeals.


  • An Update on Sound Transit’s Motion for Summary Judgment

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

    As previously noted, the King County Superior Court last Friday granted Sound Transit’s motion for summary judgment. At the hearing, the Court provided an oral ruling, which it entered as an order this week. The order is available for review, with the transcript of the hearing attached (the Court’s oral ruling begins on page 35 of the transcript). The City invites its residents interested in the decision to review it carefully.

    The City respectfully disagrees with the Court’s order. For example, the Court held that the City had no right to file a lawsuit, which in the City’s view would impermissibly render the Settlement Agreement unenforceable and was not supported by the facts before the Court. Additionally, the Court held that the conditions the City imposed on Sound Transit’s permit applications (ones that required Sound Transit to respect the conditions to which it agreed in the Settlement Agreement) constituted impermissible “additional mitigation.” This too was contrary to the law and the evidence before the Court.

    Contrary to information that has been circulating, the Court did not rule that former City staff agreed to Sound Transit and Metro’s demands for changes to the Settlement Agreement.

    The City and Sound Transit struck a deal four years ago. Since then Sound Transit has acted (and argued in court) that it does not need to follow that deal. The City strongly disagrees and continues to evaluate its options going forward.

  • An Update on the City’s Motion for Preliminary Injunction

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

    This morning the King County Superior Court held a hearing on the City’s motion for a preliminary injunction and Sound Transit’s motion for partial summary judgment. In a ruling during the hearing, the Court denied the City’s motion, which sought to enjoin construction of a curb cut on the north side of North Mercer Way for bus layovers. The Court substantially granted Sound Transit’s motion for summary judgment as well. Sound Transit’s motion pertained to many, but not all issues in dispute between the parties.

    The City respectfully disagrees with the Court’s decision and is evaluating all of its options. The City expects to post the Court’s written orders to the City’s Let’s Talk page when those orders are entered by the Court.

    UPDATE | 12/22/2021: The Court issued an order granting Sound Transit's motion for summary judgement, denying the City's motion for preliminary injunction.



  • An Update on the Mercer Island Transit Interchange Litigation

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

    Last week, the City of Mercer Island sought narrowly-tailored relief from the King County Superior Court. The City seeks an order prohibiting Sound Transit from constructing a curb cut on the north side of North Mercer Way as a part of the construction of the Mercer Island Transit Interchange. The curb cut is in violation of the 2017 Settlement Agreement between the City and Sound Transit, and Sound Transit admits the curb cut will be used for purposes that the Settlement Agreement prohibits. Sound Transit has proceeded with plans for construction in violation of its obligations under the Settlement Agreement. The City believes it is important that the parties’ disputes over the Settlement Agreement be resolved before the City’s streets are altered in ways the Settlement Agreement does not authorize.

    Because the City supports both East Link and the Mercer Island Transit Interchange, the order the City seeks is very narrow. It would allow Sound Transit to proceed with the vast majority of the project, prohibiting only the disputed curb cut until the parties can each have their day in court on the Settlement Agreement dispute - the City is confident in its legal position. The Court will consider the City’s request at a hearing on December 17, 2021.

    The City has also learned that Sound Transit has filed a motion for summary judgment and is asking the court to say that it has complied fully with the Settlement Agreement and that the City is in violation of the agreement.

    In the years since the Settlement Agreement was approved, Sound Transit repeatedly ignored the City’s rights under that agreement and failed to meet its own obligations under that agreement. Instead of engaging in good faith with the City, it has moved forward without regard for the agreement it reached, rejecting the City’s many attempts to work cooperatively with Sound Transit to find a mutually acceptable resolution.

    The City of Mercer Island fully rejects Sound Transit’s arguments and will oppose its motion for summary judgment.

  • An Update on Sound Transit's Land Use Petition Act Appeal

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

    Earlier today, the Superior Court issued an order granting Sound Transit’s Motion to Strike the City’s Notice of Supersedeas. This means there is no stay in place of the Court’s earlier order in the Land Use Petition Act appeal directing the City to issue Sound Transit permits to construct bus layovers on the north side of North Mercer Way. Consequently, the disputed permit has been issued to Sound Transit in compliance with the Court’s order.

    Fortunately, the Court’s decision is not a ruling based on the terms of the Settlement Agreement or the remedies that it may later provide. The City will continue to litigate its 2020 lawsuit against Sound Transit for breach of the Settlement Agreement which is unimpacted by today’s decision.

    On Friday, September 3, King County Superior Court issued an order in the City’s 2020 Settlement Agreement Lawsuit with Sound Transit clarifying and confirming that the costs awarded to the City for Sound Transit’s discovery misconduct include expenses incurred by the City to review Sound Transit’s document dump. The clarification and confirmation was sought by Sound Transit. The City will be recovering $58,985.05 from Sound Transit.
