Article 8.1 - Street Frontage Required
Any lot on which a building (or buildings) is to be erected or use is to be established shall abut a public street with the following exceptions:
1. Any lot for which a residential use has been legally established prior to the effective date of this ordinance in accordance with provisions permitting establishment of use on a lot served by a private and exclusive recorded easement of at least 15 feet in width connecting said lot to a public street, may be used as if it abutted a street, provided that it is served by a driveway located on said easement. A lot of one (1) acre or more in area created through a division of land not subject to the subdivision ordinance shall be eligible for issuance of a permit to establish a single-family detached house, provided the lot is served by a private and exclusive recorded easement or fee-simple projection of the building lot at least 15 feet in width connecting said lot to a public street. A driveway accessible by emergency equipment must be located on said easement or lot projection. Lots created under these provisions shall be known as “easement-access lots” and “flag lots,” respectively.
2. Any lot for which a non-residential use has been legally established prior to the effective date of this ordinance in accordance with provisions permitting establishment of use on a lot served by a private, exclusive recorded easement of at least 15 feet in width connecting said lot to a public street, may be construed in the same manner as a lot abutting a street provided that it is served with a driveway built to appropriate standards located on the permanent, recorded easement.
3. Up to six residential lots may be served by a privately maintained easement with a minimum 20-foot right-of-way if designed according to the specifications of the Rural and Transitional Farmhouse Cluster development or the specifications of the Rural and Transitional Conservation Subdivision.
4. A site specific development plan may be considered for approval in the TC, NC, NR, R, TR, HC, CB, CI, VS and both TND and TOD districts where residential and/or non-residential lots and/or structures front upon a private courtyard, carriageway, mid-block private alleyway with courtyard, or pedestrian way, or urban open space as defined in Article 7, part B, where adequate access by emergency vehicles is maintained by way of a street or alley and where the off-street placement of uses does not diminish the orientation of building fronts to the public street.
5. A site-specific development plan may be considered for approval in the Campus Institutional and Corporate Business Districts to permit interior lot access by private drives so long as business and emergency access is furnished to all interior building sites, and proposed buildings at the perimeter of the campus and corporate development front upon public street(s) or are buffered in accordance with this ordinance. It is intended that subdivisions be primarily served by public streets and use of private drives is minimal. Private drives may be appropriate where property configuration or environmental constraints make their use a practical alternative. Private drives shall be constructed in accordance with Retail/Mixed-Use Local Street Standards as found in the Engineering Standards and Procedures Manual and sidewalks shall be provided on at least one side of the private drive. See the Campus and Corporate Business Districts.
6. To access a lot or lots in the Highway Commercial District, where factors beyond developer control, such as a limited access highway, an existing development, or the location of an existing intersection, prohibit completing a street connection, a private drive may be substituted for the interior street which cannot be connected to the public network.
