The Portland Design Commission on Thursday got its first look at plans for an affordable housing development at 1701 S.E. Water Ave., in the OMSI District. Approximately 100 residential units are proposed for the five-story Los Colibris (“The Hummingbirds”) building.

This is the first project within the OMSI Central City Master Plan, which was adopted in 2023. The project site, tract A, is in the Central Eastside Industrial District, between the main Oregon Museum of Science and Industry building and the Pepco workshop/warehouse. The Marquam Bridge looms to the immediate west.

Holst Architecture is designing the project for owner/co-developer Hacienda CDC and co-developer Edlen & Co. OMSI is the landowner. The project team also includes civil engineer KPFF, landscape architect PLACE, and general contractor Colas Construction.

The project is valued at $36 million, according to Portland Permitting & Development.

The proposal moves the site’s existing parking and loading access point to the north of the tract and places additional separation between the Los Colibris building and the master plan’s Open Space-2, where the OMSI waterfront education park is planned.

While the project is still in conceptual design, Holst Architecture is eyeing cross-laminated timber (CLT) for the building. The team is also looking to meet passive house standards for energy efficiency, focus on quality of light, and include vibrant colors.

Active ground-level uses would be mainly in the building’s middle and northern portions. They would include meeting rooms, a multipurpose community room with a kitchen, a lobby with mail space, office space for resident services, and property management offices. The project team proposes to keep the community room at the center of the building.

There is not enough programming to fill the entire ground floor, said Dustin Furseth, a Holst Architecture senior associate.

“I’m totally OK with having that community facility in the middle (of the ground floor) as long as there is floor-to-ceiling windows, so pedestrians have a visual connection to the greenway,” Commissioner Zari Santner said.

Some residential units are proposed for the southern end of the ground floor. Most would be situated on the west elevation, facing a garden and play area. However, two would face the Bull Run public right-of-way connecting to the greenway, four would face Water Avenue, and a two-bedroom unit would be at the corner of Water Avenue and the Bull Run area, a staff report states.

The Bull Run path is about 30 feet wide and runs along the south side of tract A, according to city spokesman Elliott Kozuch. The Portland Water Bureau owns the Bull Run, and beneath the path there is a pipe used to move water from the Bull Run watershed on Mount Hood to the Washington Park reservoir.

Commission Chair Brian McCarter suggested flipping the ground floor’s layout so the early learning center would be where the two-bedroom unit is currently. Then the early learning center would be on the more pedestrian-accessible side of the building.

“I do have a lot of concern about … the sequencing of Bull Run and the units (planned near) the property line,” Commissioner Joe Swank said.

Commissioners suggested a five-foot setback or elevation change. The design team agreed to examine how high the first floor could be constructed in accounting for the residential units situated near the Bull Run path. Landscaping would also provide a buffer for the units.

Active ground-floor space on the east elevation would be set behind an arcade – a series of arches supported by columns that create a covered walkway. The commissioners suggested a wrap-around canopy as an alternative.

The design includes an outdoor courtyard in front of the building and outdoor communal space in the back. This courtyard allows space for residents and their guests to gather and be partly sheltered from the noise of Marquam Bridge traffic.

“I think the courtyard is essential,” Commissioner Joe Swank said.
