With trees come leaves – and when they fall in the park, it’s necessary to clean them up. Join Riverside Park Conservancy to rake leaves off of our pathways, high-traffic areas, and lawns to prevent them from clogging storm drains, making pathways slippery, and smothering the grass. All leaves will be added to our compost pile and turned into valuable mulch for use throughout the park.

Project locations are listed below. Registration (required) opens October 28.

Families and volunteers of all ages are welcome!
