The Arrow Highway Mixed-Use District (AHMUD) Specific Plan Area is composed of two discrete areas at the far northwest and northeast corners of Montclair. As its name indicates, the Study Area is located along the Arrow Highway corridor, and is developed with a variety of commercial and light industrial uses that generally date to the latter decades of the twentieth century.

This plan intends to create a walkable neighborhood to the west, linking it to the linear Creek Corridor.   On the east side, this plan extends the social and economic vitality of the adjacent downtown area. It envisions the creation of a new mixed-use district through selective infill within the existing commercial area, arranged around a grand Central Park.
