EUGENE, OR-Arlie & Co. showed off sketches for a 38-acre planned unit development in north Eugene this week and was expected to begin filing for the necessary approvals by the end of the week.

Plans show office, retail, condominiums, apartments and an assisted living facility. The development would be called Crescent Village. If approval comes this fall, construction would likely begin next year, with substantial completion as much as a decade away.

The site lies east of Coburg Road and north of Crescent Avenue. Arlie says it will likely sell off pieces of the site to others who will construct most of the buildings. Arlie acquired the property earlier this year for $6.6 million. The seller, PeaceHealth, at one time sought to build a hospital on the site.

The developer envisions 100,000-sf of office and 140,000-sf of retail on the site, which is why it is moving forward with the project as a planned unit development. The bulk of the property is currently designated for high-density residential use and “limited commercial uses,” but the planned unit development process allows for weakened land use restrictions to accommodate mixed-use development.

A neighboring 10-acre project is also in the works. A group Eugene doctor Charles McGlade has plans to develop two four-story office buildings totaling 159,000 square feet. McGlade’s planned unit development would be called Summer Oaks/Crescent Center. Arlie sold the land to McGlade last year with project approvals for the project already in place.
