PORTLAND — This Saturday, in celebration of the 17th Annual National Public Lands Day, the City of Portland’s Public Services Department will host a volunteer clean-up effort at one of the city’s cherished parks, Riverton Trolley Park.

National Public Lands Day is the largest volunteer effort to improve and enhance public lands. An estimated 170,000 volunteers will grab shovels and gloves to improve the nation’s public lands this year at more than 2,300 sites across the country.

First established in the late 1800s, Riverton Trolley Park welcomed throngs of people who paid five cents to take the trolley from Portland.

Today, the park encompasses 36 acres and offers a wide variety of flora and fauna, and a trail network for hiking and cross-country skiing.

Due to erosion from flooding, some of the Trolley Park trails have deteriorated and require repairs.
