Where other options for access to parking spaces exist, such as from an alley or a different street, access to parking shall not be from a section of street where preferred uses are required in accordance with § 3305; or from Martin Luther King Jr. Avenue, S.E., Dogwood Street, 13th Street, or Oak Drive.
Approval of a driveway under this chapter shall not be interpreted to imply permission for a curb cut in public space. An applicant for a driveway with a curb cut in public space shall have the responsibility to obtain all other necessary approvals and permissions.
