The labyrinth of winding streets demarcating the Moroccan city of Fez dates back the 9th century. But since the 1950s, the city has become heavily polluted from neglect and the chemicals coming from nearby leather tanneries. This article profiles the 20-year plan that one native architect--with support from a team composed of urban planners, landscape architects, and designers--developed as part of an effort to restore the ancient city's natural beauty. In doing so, it overviews the plan's evolution, noting the professional recognition that the plan itself has garnered. It also describes the plan's critical elements: Developing sewage treatment plants, cleaning polluted sites, constructing gardens and outdoor spaces, and relocating the tanneries.
