Metro Transit is proposing to improve pedestrian and bicycle infrastructure on SW 100th Street between 10th Ave SW and 16th Ave SW in White Center, and they’re seeking public input.

Metro’s proposal includes adding missing sidewalk sections, building curb extensions and safer pedestrian crossings, adding flashing beacons, and installing climbing lanes for bikes.

Part of the new sidewalk along SW 100th Street at the White Center Natural Area would slightly extend into a wetland buffer. To offset this, Metro is proposing to install habitat structures and plantings, among other measures. Construction is planned for the second half of 2021.

As the lead agency under Washington’s State Environmental Policy Act (SEPA), Metro has determined that this project is not likely to significantly harm the environment. A Determination of Nonsignificance will be published in the Seattle Times and Department of Ecology Register, with a comment period of Feb. 3 through Feb. 17, 2020.

The adopted National Environmental Policy Act Categorical Exclusion and SEPA Determination of Nonsignificance for this project are available during normal business hours at the White Center Library (1409 SW 107th Street, Seattle). Electronic copies are available on request. Metro will not act on this proposal until the close of the comment period. Comments must be submitted by 5 p.m. on Feb. 17.
