ALLEY ? ??
巷道
An alley is a narrow service thoroughfare running through the middle of a block that permits access to the rear of the property. Alleys provide access to off-street parking, and typically are used for utility easements, service, and trash removal. They are paved from property line to property line, with drainage at the center of the thoroughfare achieved by an inverted crown. Alley right-of-ways may be as narrow as 12 feet (3.7 meters). However, in newer developments they tend to be 25 feet (7.6 meters) in width to accommodate the desires of fire marshals and utility officials who insist on the largest dimension for the convenience of drivers or life safety reasons. New urbanists have promoted the use of alleys to create a better pedestrian experience,accomplished by accessing garages from the rear and reducing curb cuts for front-loaded garages.
