This project began in 1995 in the Columbia Slough watershed and today is active in all Portland watersheds. The Reveg team works on restoration projects with other City of Portland bureaus and many public and private groups. The restoration work improves water quality, controls erosion, reduces stormwater pollution, and enhances fish and wildlife habitat.
In fall 2011, the Revegetation team began treating English ivy and removing English holly and laurel in the 146-acre River View Natural Area in southwest Portland. The forested site has several spring-fed streams that contribute clean, cold water to the Willamette River.
Throughout Portland, English ivy and other invasive species have compromised native understory plants. The Revegetation team works with regional partners and private contractors to collect and grow native groundcovers (e.g., fringecup, Pacific waterleaf, large-leaf avens) that aren’t commercially available to produce seeds and create a sustainable regional native seed source.
This team designs, plants, inspects, and maintains stormwater management facilities, which include stormwater ponds and green streets. In 2011, the Revegetation program team designed and constructed the Willamette Park Swale to capture and treat stormwater runoff from the parking lot adjacent to the river. The team also provides long-term maintenance for about 900 green streets in Portland, and that number is growing all the time. The Stormwater Management Facilities team helps the public understand green street benefits and how green streets work.
