Designing for the Future

Garden Expansion Project

In 2016 a master plan for Leach Botanical Garden was completed, in partnership with Leach Garden Friends, the City of Portland, and the Portland Development Commission (now Prosper Portland). The Design Team, headed by Land Morphology with Olsen Kundig, Architects, led us through a process that resulted in a vision intended to delight and inspire visitors while also communicating deeper messages about the deep connections between people and plants.

construction FAQs

Are you open during construction?

Leach Garden will be open during construction although areas where work is taking place will not be accessible. The Garden offices and the Manor House and Gift Shop may be inaccessible during some parts of the construction. We will note such changes on the website when possible, but please note that construction schedules are subject to changes with short notice.

Where can I park?

Parking for the moment is available at the Creekside Parking across the Johnson Creek bridge from the Garden entrance. Two handicapped spaces at that entrance are also available at the moment. Parking on the street side on SE 122nd Dr. is legal unless posted otherwise. We will update any changes.

Can I still walk around the garden?

Yes! During the construction, areas of the Garden will be closed to the public as the construction unfolds. We will post notices on site and online as the project unfolds to provide updates on access.

Can I still rent space at the garden?

Rentals in the Garden will continue to take place dependent on the dates and times. The best information about rental for a particular date can be obtained by emailing or by leaving a message on our RENTAL line at 971-832-9081. The rental team will return your message as soon as possible.

What is being built?

Elements of this project phase will incude the Aerial Treewalk, Fireside Arbor and Terrace, Pollinator and Habitat Garden, Gathering Green, new accessible pathways, parking areas, and restrooms. A main path and staircase from the new entry will take people on a direct route from the Upper Garden to the Manor House. Claybourne Street will become the main entry to the Garden. The main part of the Garden will be fenced and gated. Also included is a new 24/7 pathway taking people from the intersection of SE 122nd and Claybourne down to the sidewalk outside the Manor House entry gates.

Are trees affected by the construction?

Trees are affected by the construction. The vast majority of trees in the construction zone will be protected under the City of Portland standards. The Aerial Tree Walk is designed so as to have the least possible impact on trees. In the Upper Garden areas in the project zone, there are trees that will be removed. Importantly, large numbers of new trees will be planted as part of the project.

How long with the project take?

The Upper Garden project construction is expected to be completed by late fall of 2020. A firm date for a dedication ceremony and opening will be selected when we are closer to completion.
