Monday Properties Secures Arlington County Board Approval of a Major Site Plan Amendment, Paving Way for Rosslyn Mixed-Use Redevelopment

Monday Properties announced today that the Arlington County Board granted approval of a major site plan amendment for 1401 Wilson Boulevard and 1400 Key Boulevard. With the county's approval secured, a transformative mixed-use development at the 2.1-acre site encompassing both 1401 Wilson Boulevard and 1400 Key Boulevard in Rosslyn can now move forward, signaling confidence in the project's alignment with established planning goals.

The two contiguous parcels, currently occupied by a pair of 12-story office buildings constructed in 1964,will be redeveloped into a landmark mixed-use destination featuring two 27-story multifamily residential towers totaling 831 residential units, 28,959 square feet of ground-floor retail including a community-anchoring grocery store and a partially above-grade parking structure, with 52% of the site allocated for publicly accessible open space.

"This approval is a significant milestone for Rosslyn and for the region, and we are proud to advance a project that meets, and in many respects exceeds, the land use recommendations set forth in the Rosslyn Sector Plan," said Tim Helmig, Co-Chief Executive Officer and Managing Partner, Monday Properties. "By delivering 831 new residential units in one of the most transit-rich neighborhoods in the Washington, D.C. metro area, we're building on the Westreich family's legacy of developing signature projects in Rosslyn since the late 1950s."

The amended site plan preserves the integrity of the previously approved design while optimizing tower placement and retail configuration. The project complies with Rosslyn Sector Plan recommendations for tower separation, open space and pedestrian connectivity; upholds the 18th Street Corridor guidelines; and will achieve LEED Gold certification in line with prior commitments. Street-level retail spaces will animate N. Oak Street, Wilson Boulevard and N. Nash Street.

“With this approval, we will be able to deliver the start of the 18th Street Corridor with a landscape rooted in the region's geology with terraces, overlooks and a monumental plaza, while weaving biophilic design throughout to strengthen connections to the natural world and enhance the pedestrian experience,” Helmig added. “The approval also ensures Rosslyn gains not just housing, but a more complete neighborhood with the addition of a full-service grocery store further strengthening Rosslyn's retail fabric.”

Rosslyn stands as the key economic center of Northern Virginia, embodying an impressive array of coveted amenities. The region sits on top of three Metro lines and is linked to five major interstates, ensuring unparalleled connectivity and accessibility that alleviates commuter concerns. Its highly walkable, urban environment offers an array of local restaurants, retail and green spaces. Residents benefit from unique access to lifestyle amenities including the Potomac River, extensive bike and pedestrian trails and outdoor recreation opportunities as well as seamless connectivity to Georgetown and the greater DC region, an appealing draw for residents seeking convenience and a vibrant, urban atmosphere.

Monday Properties’ project team will include Shalom Baranes Associates as architect of record, Parker Rodriguez as landscape architect and VIKA Virginia as the civil engineering and site design firm.
