Except in unusual cases, alleys or loading courts must be provided in business blocks. Alleys are optional in residential districts but are considered undesirable except where alleys of adjoining subdivisions would be closed or shut off from access by the failure to provide alleys in the new subdivision. Alleys shall have a minimum width of twenty (20) feet. In case of intersecting alleys a centerline radius of twenty (20) feet shall be required.
