In collaboration with Washington State Department of Transportation, Seattle Parks and Recreation will be winterizing the irrigation line from the Foster Island Bridge to the Washington Park Arboretum maintenance building along Foster Island Road. This work will aid in plant establishment underneath the new 520 bridge by allowing year-round irrigation. The work involves installing an electrical line in the same trench as the existing water line to prevent the water line from freezing in the winter.
Construction will require temporary closures for the north entry of Broadmoor at Foster Island Road, the Washington Park Arboretum maintenance parking lot, and the trail at the Foster Island Bridge.
Construction is anticipated to last approximately three weeks and will begin Monday, October 1, 2018 at the Arboretum maintenance parking lot. The Arboretum maintenance parking lot will be closed October 4 through 8. The north entry of Broadmoor will be narrowed to one lane October 8 through 12, and the work on the trail is scheduled from October 15 through October 19.
We apologize for the inconvenience and appreciate your patience. For more information on the project please contact Katie Bang, Seattle Parks and Recreation, at 206-684-9286 or email@example.com.
