The Vancouver City Council has approved an amendment to the sale of a city-owned building and its adjoining property, paving the way for another urban redevelopment project in downtown Vancouver. In a deal worth $5 million to the city’s general fund, the city will sell the two-story Esther Short Building, 610 Esther St., for $3.2 million to West Park Partners LLC, owned by developer David Copenhaver. That sale is set to close Friday.In its Monday action, the City Council gave Copenhaver an additional 90 days to pull together the financing to buy the property west of the building for $1.8 million. The vacant lot is approximately three-quarters of a city block in size and is now used as a surface parking lot next door to the Esther Short Building. Copenhaver plans to remodel the existing building for office space and he has already secured a tenant, he told city officials. He plans to develop the parking lot into a six-story apartment complex with at least two levels of parking, although no formal development plans have been submitted.Copenhaver confirmed by text message on Tuesday his plans to buy the property, but he did not return a request for comment.If built, the apartment building would rise just south of the five-story Esther Short Commons building at 555 W. Eighth St., which includes 160 apartment units and ground-floor retail space fronting Esther and Eighth streets.
