Renaissance Centro and Fairfax County government are tussling over how to bring affordable housing to a new Tysons luxury development.

The Reston-based developer wants to build Arbor Row Block D a 25-story, 140-unit condo building anchored by ground-floor retail, which would be part of landowner Cityline Partners' Arbow Row project, a 2.2M SF redevelopment of West Park's office park, the Washington Business Journal reports.

Cityline, Renaissance Centro and county planning staff can't agree on how to meet affordable unit requirements. In exchange for building workforce development units, or units affordable to households earning from 60% to 120% of the AMI, Renaissance Centro would get building height requirement flexibility and 20% bonus density.

However, Renaissance Centro is proposing donating cash to the county's affordable housing fund in lieu of including the WDUs on site, a proposal on which Fairfax County planners have pushed back. [WBJ]
