What does the concept of "density" in site planning refer to?

The concept of "density" in site planning specifically refers to the number of structures per unit of land area. It is an essential factor in urban planning that impacts various aspects of design, including the distribution of amenities, infrastructure needs, the character of neighborhoods, and overall land use efficiency. Density can influence the social dynamics within a space, such as community interaction and access to services.

In urban settings, higher density can lead to more compact development patterns that enhance walkability and reduce dependency on vehicles. Conversely, lower density may imply more open land, greater distances between structures, and potentially more green spaces but can also contribute to urban sprawl. Understanding the specific metrics of density helps planners create balanced developments that respond to the needs of populations while considering environmental sustainability and resource allocation.

The other concepts, such as the height and bulk of buildings, total area occupied by residential units, or the percentage of green space in a development, do not directly define "density." Instead, they reference other aspects of site planning that contribute to the overall character and functionality of a project.
