B. Access to Public Streets. All lots shall have direct or indirect access to a dedicated public or private street. Indirect access through an easement may be approved by the City for alternative lot layouts defined in this UDO, based on considerations of pedestrian, bicycle, motor vehicle, and emergency vehicle access and safety, and through connectivity.
C. Double Frontage Lots. Double frontage lots shall not be permitted adjacent to local or collector streets, and shall be avoided to the maximum extent practicable along arterial streets. Where double frontage lots cannot be avoided, buffering of back yards from those streets shall include a landscaped buffer at least 20 feet in width between the rear lot line of any residential lot and the closest edge of curbside landscaping area adjacent to the street, per Section 146-4.7.3.
D. Remainder Parcels Prohibited. No subdivision of land shall result in any remainder parcel or tract that does not otherwise meet the standards for a required open space, drainage area, buffer, or other area required by this UDO to be included in the development.
E. Street Fence Ownership and Maintenance. Where rear lot lines face an arterial street, the lots shall comply with the requirements of Section 146-4.7.9 (Fence and Wall Regulations), which are designed to prevent the creation of "fence canyons" A note reading as follows shall appear on the plat:
"All new neighborhood fences along arterial street shall be maintained by a Title 32 District or homeowners’ association and any fence replacement shall comply with the Fence and Wall Standards in Section 146-4.7.9 of the Aurora Unified Development Code.”
