Helen Putnam Expansion 

Construction on the new parking lot is ongoing, and we anticipate completing all of the necessary improvements in October of 2021.

See Windsor Drive Parking Lot Plan

What & Why?

The park expansion project will provide a new access route to the existing network of trails at Helen Putnam Regional Park. The proposed construction includes a trail and parking lot, with a portable restroom, trailhead signage and trail map.

This new park access provides dedicated parking close to the community and a new trail which is designed to roll and flow up the hill, minimizing steep climbs so that it can be enjoyed by trail users of all abilities.

What's Next?

We are putting the finishing touches on the new parking lot and trail. Signage, accessible walkways and rocked trail to the West Ridge community will be completed in the fall of 2021.
