What does "density" refer to in subdivision development?

In the context of subdivision development, "density" specifically refers to the number of dwelling units or structures per acre of land. This measurement is crucial for planners and developers as it helps determine how many homes can be constructed within a given area, impacting various factors such as infrastructure needs, traffic patterns, and overall community layout.

Understanding density is essential because it influences the character of the neighborhood. High-density developments may lead to more units being packed into a smaller area, which can create a vibrant community but may also strain local resources. Conversely, low-density developments provide larger lot sizes and more open space but can limit the number of residents or businesses in the area.

The other concepts mentioned, such as the total area of open space or the average size of buildings, while important for planning, do not accurately define what density is. Likewise, total population capacity is derived from density but is a broader and more complex measure, as it incorporates factors like household size and occupancy rates. Hence, the definition that pertains directly to density is the number of dwelling units or structures per acre of land.
