Arlington County Board approves major Roslyn redevelopment and multiple ordinances; votes, grants and appointments summarized

Arlington County Board members approved a package of major land-use, transportation and administrative actions during a long recessed meeting on July 22. The board voted unanimously on a large Roslyn redevelopment known as “1 Roslyn,” approved lower posted speeds on five county road corridors, adopted the fiscal year 2026 audit work plan and approved a set of grant amendments and legal settlements. The board also confirmed a series of appointments and authorized an acting county attorney to fill the county attorney role through a pending transition.

Why it matters: The votes move several high-profile projects and county priorities from planning toward implementation — most notably the 1 Roslyn project that will add hundreds of residences near the Rosslyn Metro, and a package of traffic-safety changes the board framed as part of its Vision Zero work.
