Celebrate Earth Day April 22 with a behind-the-scenes peek at Port wildlife habitat and environmental projects. The narrated bus tour will include Gog-le-hi-te II wetlands along the Puyallup River and the Hylebos Marsh, where construction will begin this year on what eventually will become 23 acres of restored freshwater and intertidal marsh, forested upland and riparian habitat along Hylebos Creek.

Visitors also will view the Port’s pioneering “tree in a box” to prevent water pollution. This pilot project is the first time the low impact development technology has been used in an industrial setting. Latest results show the native trees filter out 90 percent of zinc from stormwater runoff.

The bus will leave at 9:30 a.m. from the Fabulich Center, 3600 Port of Tacoma Rd. in Tacoma, and return about noon.

Space is limited for this free tour, and reservations are required. Children age 6 and older are welcome. Photo identification is required for passengers 17 years of age and older. This tour will involve minor hiking; comfortable shoes and weather-appropriate clothing are recommended.
