Gating of Streets

a. The use of gates, manned or unmanned, to control vehicular access on any public street or alley is prohibited except at railroad crossings. b. The use of gates, manned or unmanned, to control vehicular access on a private street, alley, or driveway may be allowed only with if the Town Engineer, after consulting the Fire Chief, determines that gate would not restrict vehicular access to an existing street, restrict timely access by emergency vehicles, or solely serve to isolate or segregate an organization or segment of the population from access. This requirement does not apply to a driveway serving an individual single-family detached, duplex, manufactured home, or single-family attached dwelling. F. Intersection Sight Distance Areas Intersection sight distance areas shall be established at each corner of all intersections of streets, as well as intersections of driveways and streets, in accordance with the standards in the Engineering Design and Construction Manual. Within intersection sight distance areas, development and landscaping shall be restricted to enable motorists approaching the intersection to see and react to vehicular traffic approaching the intersection from other directions, in accordance with standards in the Engineering Design and Construction Manual.
