North Fork/Spring Valley Revegetation
In 1999 the City of Federal Way removed an old, partially blocked culvert under a disused farm road in the Spring Valley Open Space property. This project improved fish passage to the upper reaches of the North Fork of Hylebos Creek, and restored 90 feet of stream channel with log structures and pools.
Following construction, on Earth Day 2000 the Friends organized their first ever volunteer habitat restoration project. Not knowing what kind of response to expect, the Friends’ staff was delighted to have 78 volunteers turn out to plant 614 native trees and shrubs.

Brooklake Habitat Restoration Project
The project site is a former blueberry farm bordering 800 feet of the West Branch of Hylebos Creek on the downstream end of the West Hylebos Wetlands. The riparian area had been cleared by previous landowners and the riparian area and stream channel were damaged by flooding. The city of Federal Way purchased the property in 1991 and managed part of the property as a blueberry farm. The rest of the property was overgrown with invasive Himalayan blackberries. In several phases, since 2002, the Friends cleared Himalayan blackberry from 80,000 square feet and replanted with native trees and shrubs. The Friends also installed 14 engineered large woody debris structures in the stream to enhance salmon habitat and stream structural diversity.

Spring Valley Montessori riparian restoration
A 600 feet length of the west branch of Hylebos Creek running through the Spring Valley Montessori School was damaged extensively by flooding. Beginning in 1996, volunteers removed blackberries from the stream corridor, followed by stream channel and bank stabilization performed by the city of Federal Way. Post-construction, the city planted native trees on the streambank, followed by understory planting of native shrubs and trees performed by volunteers.
