Arlington County Board Approves 328 Unit Residential Project at 4601 Fairfax Drive

The Arlington County Board convened on July 19, 2025, to discuss a significant site plan amendment for the property located at 4601 Fairfax Drive. The proposal involves the demolition of an existing 12-story office building and the construction of a new seven-story residential building with 328 dwelling units, alongside modifications to zoning standards for increased density.

The meeting began with a presentation by Matt Pfeiffer from the Department of Community Planning, Housing, and Development. He outlined the key aspects of the project, including the retention of a below-grade parking garage and the vacation of a portion of a public street and utilities easement. The site, currently developed with an office building, is adjacent to Marymount University and the Ballston Wetland Park.

Pfeiffer emphasized that the project aligns with the county's goals of transforming underutilized office spaces into residential units, as outlined in the county's policies. The proposed development aims to exceed the base density by 65 units, facilitated by a $2 million contribution to the Affordable Housing Investment Fund (AHIF), which is expected to leverage additional off-site affordable housing units.

The architectural design of the new building has evolved through community input, with enhancements made to improve the pedestrian experience and integrate biophilic elements. The design includes a stone colonnade and a landscaped gateway along Fairfax Drive, addressing previous concerns about the building's relationship with the surrounding environment.

The project has received unanimous support from various commissions, including the Transportation Commission and the Housing Commission. However, staff recommended a standard three-year term of validity for the site plan, rather than the five years requested by the applicant, to ensure adaptability to changing conditions.

In conclusion, the Arlington County Board is poised to approve the site plan amendment, which promises to revitalize the area by replacing an outdated office building with a modern residential structure, enhancing the community's housing options while adhering to environmental standards. The board's decision will be crucial in shaping the future development of the Ballston sector.
