Garden Corner Curves

Frequently Asked Questions

  • When and why will the road need to be closed?
    The work in and around Hedges creek is required by permitting agencies to be completed between July 15th and September 30th. To enable the contractor to most quickly and efficiently construct the roadway and culvert improvements at the lowest possible cost to the city, the road will be closed to allow for this work. The road closure will begin on June 28th and continue until work is completed sometime in October. There will be NO access through the corridor once the road is closed. We understand this is inconvenient, but it is the only way to achieve the community vision. Please find a detour map here.

  • How long will construction continue?
    Construction began in August 2020 and is expected to continue until December 2021. Phase 2 construction began in January 2021. Some portions of the culvert and associated roadway work can only occur during the driest summer months, so some construction will not be completed until the Summer 2021. See project schedule here.

  • Can I still go to The Garden Corner nursery? 
    Yes! The Garden Corner remains open for business. You will need to access the nursery from the south, see road closure map for more details. 

  • How can I stay up to date regarding the construction schedule?

  • Why did the culvert installation get postponed until the summer of 2021?
    The Army Corps of Engineers only permits work within the creek between July 15 and September 15. The culvert itself has a six week lead time for fabrication and the contractor could not get the culvert fabricated and shipped in time to make the July 15-Sept 15 2020 work window. Any new roadway work that would direct stormwater through new stormwater treatment areas and towards the culvert also needs to wait until the culvert work is complete to avoid flooding due to the existing undersized culvert.

  • How is this project funded?
    In May 2018, Tualatin voters approved a $20 million bond measure to support high priority transportation porects, distributed city wide. Garden Corner Curves was identified as a priority project that will improve neighborhood safety.

  • Why can’t the City lower the speed limit?
    By law, the Oregon Department of Transportation is responsible for establishing speed zones. Regional traffic engineering staff conduct engineering investigations to determine recommendations for safe speeds on local roads and streets. Currently, ODOT establishes speed limits through the 85th percentile speed. This is the speed at or below which 85 percent of the vehicles are currently traveling. This is used as an indication of the speed most drivers feel is reasonable and safe. In the case of the Garden Corner Curves, a speed limit established using the 85th percentile speed may not result in a reduction in the speed limit and could even result in an increase in the posted limit. More details of ODOTs process for establishing speed limits can be found here.

  • Why can’t the road be reclassified to local use only?
    The roadways which constitute the Garden Corner Curves (105th Avenue, Blake Street and 108th Avenue) are currently classified by the city as minor collector roadways. This is defined by the city as a roadway which "connects neighborhoods with major collector streets to facilitate movement of local traffic and serves as primary routes into residential neighborhoods". This section of roadway is one of a few North-South routes within this section of the City and reclassifying the roadway to local traffic only could have significant impacts on the greater system and would not be consistent with its current function without alternative north to south routes being designed and constructed.
