Which of the following layouts is characterized by deep, narrow lots?

The grid layout is characterized by a system of streets and blocks that creates a series of intersecting roads, resulting in a pattern that typically allows for deeper, narrower lots. This design is efficient because it maximizes the number of lots and enhances accessibility within the area. When planning or analyzing urban environments, a grid layout's structure facilitates the arrangement of properties in a way that supports population density, ease of navigation, and efficient land use.

In contrast, other layouts such as alley layouts often prioritize access through alleyways instead of creating deep lots. The Z-lot layout features a more irregular shape, which does not emphasize deep, narrow configurations. Wide shallow layouts, conversely, tend to provide more extensive frontage while sacrificing the depth of the lots. Therefore, the defining characteristic of the grid layout makes it the correct choice for the question regarding deep, narrow lots.
