What is the purpose of an alley in a subdivision?

The purpose of an alley in a subdivision primarily revolves around providing access and logistical support rather than serving as a main roadway or a noise barrier. By breaking a block, alleys create a separation that can facilitate convenient passage for pedestrians and emergency vehicles. This design makes it easier for these types of vehicles to navigate through the subdivision without interfering with primary traffic patterns on busier streets.

While alleys do enhance accessibility to areas such as garages and backyards, this is not their primary function. The intention behind including alleys is more about enhancing the subdivision's flow and ensuring emergency services can access homes quickly. Their design also tends to promote a more pedestrian-friendly environment, contributing to the overall safety and functionality of the neighborhood.
