The Land Use map shows five categories of use: commercial, residential, industrial, institutional, and transportation. These five categories combine more specific categories used by the Philadelphia City Planning Commission (CPC). The WPDD uses standard land-use colors, and the sub-menu itself is coded to provide a type of key or legend. The more specific designations utilized by the CPC appear in the center of each property. For example, all residential properties appear as a yellow color, but if you look at a particular property, an "M" might indicate that the site is designated as a Multiple Dwelling Unit/University Dormitory.

Maps of the entire project area were produced in 1987 for the West Philadelphia Landscape Plan. Only the immediate Mill Creek area, however, has been digitized. A more detailed image of the Mill Creek neighborhood land use is also part of this Web site.
