Mayor Anthony Williams urged the D.C. Council on Monday to adopt the District’s revamped long-range plan before the end of the year, despite an impending overhaul in both the executive and legislative branches.

Under development for four years, the revised Comprehensive Plan is a broad guide designed to shape how the city and its neighborhoods will grow through 2025, from housing and transportation to the environment and the arts. The draft document was delivered to the council in mid-July, just as legislators were leaving for the summer recess.
