|On track to become a LEED ND Platinum community, Hassalo on Eighth transformed an underdeveloped area - previously a vast parking lot - into a vibrant, eco-friendly, 24-hour community just minutes from downtown Portland. Hassalo on Eighth is the city’s largest-ever residential development, encompassing four blocks with 657 sustainable luxury units in east Portland’s Lloyd Eco-District. Located between NE Multnomah Street and NE Holladay Street on the north and south, and 9th Avenue and 7th Avenue on the east and west, the three buildings offer over 50,000 square feet of retail space, 1,200 below-grade parking stalls, a large Bike Hub with over 1,000 bike stalls plus lockers and shower facilities, and treat their wastewater for reuse onsite. |
Close to downtown, the street car and highly walkable, the multi-use project is set to transform the district. The state-of-the-art urban redevelopment encompasses three new multifamily housing buildings of varying density: Velomor, a 6-story, 177-apartment mid-rise on the southeast corner; The Elwood Building, a 5-story, 143-apartment mid-rise on the northeast corner; and Aster Tower, a 21-story, 337-apartment tower on the southeast corner of the site.
Street level retail includes an anchor grocer, a community plaza, and immediate access to both the Portland MAX light-rail and the Portland Streetcar systems. The development team is also pursuing LEED Platinum certification for all three buildings. "Site specific strategies include: rainwater harvesting and treatment; on-site wastewater treatment and re-use with infiltration; district energy; natural daylighting; access to public transportation; among others," (GBD Architects).
Kyle Andersen of GBD Architects said, “We were thrilled to have the opportunity to design a large scale eco-district utilizing leading-edge technology. The integration of the multiple large green roofs covering over 38,000 square feet and the largest on-site urban waste water treatment facility in North America (aka N.O.R.M. – Natural Organic Recycling Machine) were key components to this project. It is because of the innovative water management design elements that a significant refund on SDC’s [system development charges] was provided by the city’s Bureau of Environmental Services.”
Configured with a U-shaped plan, the Velomor was the first building to open and resident amenity spaces include an enclosed private garden courtyard, and a fitness center and community room at the ground floor. The roof terrace at the sixth floor provides amenity space for the residents with a breezeway connecting the two sides. The Aster Tower also boasts a rooftop terrace for relaxing and barbecues for entertaining. The extensive greenroofs by Columbia Green Technologies cover 25,650 square feet. Columbia Green Technologies’ Extensive Layered system planted with sedum tiles was used.
|The entire development, along with an existing office tower, is connected to N.O.R.M. (Natural Organic Recycling Machine), a decentralized treatment and reuse system located in the community's main plaza. N.O.R.M. treats and recycles 100% of the grey and black water created by each of the property's three residential buildings, along with the Lloyd 700 Office building, through a series of trickling filters and constructed wetlands.|
All site sewer treatment happens in N.O.R.M. instead of in the City’s wastewater treatment system and water is reused onsite, designed to meet 100% of the toilet flushing demand, cooling demand, and landscape irrigation. As a result, approximately 47,000 gallons of wastewater is diverted from the municipal sewer system daily. The N.O.R.M. system generates no waste and bio-solids and other byproducts are used as fertilizer and fuel offsite. The natural organic recycling machine is expected to reduce water usage for the four buildings by 50 percent, which is about 7.3 million gallons of water per year. The team who worked on N.O.R.M includes: Biohabitats; Turner Construction – Concrete Structures; D&R Masonry –Waterproofing membrane; JH Kelly – Plumbing systems; Berg Electric – Electrical Systems; Coffman Excavation – Fill media; and Teufel - Landscape.
The project’s greenroofs reduce peak flows during large rain events by retaining stormwater, preventing stormwater flows from overwhelming the system. Due to the cutting edge stormwater management strategies the project was allowed a refund of the system development charges (water and sewer fees) the owner had to pay for this new district. The refund totaled $1.48 million, almost half of the City’s three million dollar fee.
"The City of Portland teamed up with Hassalo on Eighth to support NORM and offered creative technical, policy and financial support due to NORM’s ability to reduce wastewater sent to the city’s limited sewer system... “Hassalo on Eighth embraces Portland values — innovation, environmental consciousness —with its NORM system, incredible Bike Hub, and host of environmentally friendly features,” said Portland Mayor Charlie Hales. “It sets a bar for Portland development as we continue to push ourselves to live more sustainably,” " (MHN, 2015).
Wade Lange of American Assets Trust said, "Hassalo on Eight is one of the most innovative and self-sustaining developments within a recognized Eco-District in the nation. In my opinion, this will be the modern building standard for the construction of resilient cities. The Columbia Green Technologies green roof is significant to the performance of our buildings as it retains stormwater on the roof, reducing demand on an already undersized city storm/sewer system."
Columbia Green’s CEO, Vanessa Keitges says, “Columbia Green is continuing to be at the forefront of Green Tech research and design. We strive to provide the best innovations for sustainable architecture and engineering.” The Hassalo on Eighth project is at the forefront of the National Resilient Cites trend by managing all the water onsite.
The Eco-District design strategy places emphasis on livability with sensitive planning and innovations in urban ecological infrastructure. Along with N.O.R.M., the greenroofs and rainwater harvesting gardens are part of the stormwater capture system, redirecting it away from stressed city sewer infrastructure and having a net positive impact on stormwater.
