In the development of a subdivision of single-family homes, which of the following would be the least economical?

1. Cul-de-sacs

2. Long blocks

3. Right angle (90%) intersections into major streets

4. Short blocks

The correct answer is: Short blocks

In the context of developing a subdivision of single-family homes, short blocks can be considered the least economical choice because they typically require more street construction and infrastructure development over a given area, which can significantly increase costs. Short blocks necessitate a greater length of road per unit of housing, along with potentially more intersections and curbs that need to be built and maintained, thus raising overall expenses for the developer. On the other hand, options like cul-de-sacs, long blocks, and right angle intersections into major streets tend to spread the infrastructure costs more efficiently. Cul-de-sacs can enhance privacy and reduce traffic, while long blocks minimize the amount of street per dwelling, which can translate into lower paving, curb, and gutter expenses. Right-angle intersections may also contribute to more efficient traffic flow, although they could incur some developmental costs. By considering these factors, it becomes clearer why short blocks are less economical, as they anticipate higher development and maintenance costs compared to the other configurations.
