(Updated at 5:20 p.m.) The Arlington Partnership for Affordable Housing is planning on building two, eight-story apartment buildings near the western end of Columbia Pike.

APAH is planning on replacing a surface parking lot at 1010 S. Frederick Street with the two buildings, which will contain 229 units of committed affordable housing. All of the units will be affordable up to 60 percent of area median income, with some units as low as 40 percent AMI.

To replace the surface parking, a three-level underground garage will be built.

The development is on this month’s agendas for the county’s planning and housing commissions, and is expected to go before the Arlington County Board at its meetings later this month. The project would be one of the first of its kind to go before the County Board under the Columbia Pike neighborhoods form-based code, approved in 2013.

Some in the community have expressed concern about a concentration of affordable housing on the western end of Columbia Pike, where this project is situated. County Board member John Vihstadt addressed some of those concerns at the Arlington Civic Federation meeting on Tuesday night.

“Certain people have concerns about an over-concentration [of affordable housing] on the west end of the Pike and not enough on the east end,” Vihstadt said. “It’s something that we’re going to have to come to grips with. I think we all want a mix of income in all neighborhoods as much as possible.”

APAH CEO Nina Janopaul told ARLnow.com that those concerns pale in comparison when compared to the concerns over the lack of affordable housing overall in the county. She said the civic association in which the new project is located, Columbia Forest, has lost 750 units of affordable housing in the last 15 years.

“The Columbia Pike Neighborhoods Plan calls for preserving or replacing the 6,200 affordable units, most of which are market-rate affordable and vulnerable to redevelopment,” she said. “We need to take advantage of the moment now, when the interest rates are low, to build affordable housing that will still be there in 60 years.”

The development, if approved, would add the 229 affordable units right next to APAH’s expansive, 208-unit Columbia Grove apartments. Of those units — on the 8-acre, 14-building campus — 131 are committed affordable housing. Janopaul said the buildings are Columbia Forest’s only affordable housing “at all.”

The project, dubbed “Columbia Hills,” will cost an estimated $85 million, according to APAH’s application to the county. APAH is requesting the county contribute $18.5 million from its Affordable Housing Investment Fund, which, along with the form-based code application, the County Board is expected to debate granting this month.

APAH is also planning to submit a Low Income Housing Tax Credit application next month. If all goes as Janopaul hopes, the federal government would approve the loan in the first quarter of 2016, after which construction can begin.
