Visualizing Housing Density
This presentation is designed to help visualize housing unit density in a variety of urban and suburban settings. Density is an important characteristic in relationship between land use and transportation, particularly in supporting successful transit service. However, density has many forms and applications and developments of the same density can have a very different look and feel. Density also has numerous definitions and methods of measurement.  This presentation defines density by how many housing units are in a development designated for housing, dwelling units per acre (du/acre).  In some cases, it is the parcels that comprise the subdivision. In others, it is area included in the development project or neighborhood block.

Key Points

  • Density is a number of units in a given land area (project area, subdivision, parcel).  In the residential developments used the land area includes all the area of the legal parcel or parcels.  The maps show the land area definition for each project highlighted.

  • In mixed use projects, density is the number of housing units divided by the land area of the mixed-use development (that includes area used for non-residential uses such as office or retail space).
