New affordable housing and arts and cultural space in Uptown is one small step closer to fruition, after the city’s Office of Housing opened its request for proposals for the ‘K Site’ last week.

The 11,000 square foot parcel at the corner of Second Avenue and Mercer Street was originally acquired by Seattle Center in 1999, and had been maintained as open space. In February, the City Council passed a bill transferring the jurisdiction of the property for the purpose of developing the site for affordable housing.

All proposals are required to include 100 percent affordable units — for those earning up to 60 percent of the area median income — and must incorporate at least 2,500 square-feet of ground floor space for arts and cultural uses.

In addition, the city is seeking proposals that provide at least 20 percent of its units for formerly homeless individuals and families, and is encouraging applicants to include as many units as possible that are affordable to households below the 60 percent AMI maximum.

Also under consideration is how the proposals “maximize development capacity,” within the funding and zoning limitations — measured by both the total number of units and the number of people expected to live in them — and how efficiently the plans would use city funding.

A question and answer session is scheduled for July 11 at 2:30 p.m. at Seattle City Hall (600 4th Ave.) in the Boards and Commissions Room (L280). Proposals are due by noon on Aug. 29.
