Unified Development Ordinance - Public Hearing Draft
b.
The vehicular access and circulation for a development shall provide for the extension or
connection of proposed internal public street roadways and associated rights-of-way to those
boundaries of the development site that adjoin potentially developable or redevelopable
property whenever such extensions or connections are or may be necessary to ensure that the
development site or the adjoining property will have:
(1)
At least two vehicular access points to and from an external through street system, plus
one additional vehicular access point for each additional 2,000 vehicles per day, or
fraction thereof, expected to be generated by the proposed development or by the
maximum allowable development of the adjoining property;
(2)
Convenient and efficient access by vehicles needed to provide police, fire, and
emergency services; and
(3)
Convenient and efficient access by vehicles needed to provide other public services.
333
c.
Roadway extensions and connections to adjoining properties shall be spaced at intervals
along each principal boundary direction (north, south, east, west) that do not exceed the
maximum block length established in Section 5.3.1, Blocks.
d.
An extension or connection of a public street roadway and right-of-way to an adjoining
property shall also include the extension or connection of associated bikeways or sidewalks.
e.
The Planning Director may require the provision of a temporary turnaround at the end of a
roadway extension on determining that the turnaround is needed to facilitate traffic flow or
accommodate emergency vehicles pending the roadway‘s connection to other roadways.
f.
The Planning Director may waive or modify the requirements or standards for extension or
connection of a public roadway from or to adjoining property on determining that such
extension is impractical or undesirable because it would:
(1)
Require crossing a significant physical barrier or environmentally sensitive area (e.g.,
railroads, watercourses, floodplains, wetlands, steep slopes);
(2)
Require the extension or connection of a proposed internal public street to an adjoining
property with existing development whose design makes it unlikely that the street will
ever be part of a network of public streets (e.g., the adjoining existing development has
no public streets, or there are no ‗stubbed-out‖ street rights of way or open corridors
between the proposed development site and public streets in the adjoining development
to accommodate a current or future extension or connection);
(3)
Require the extension or connection of a proposed internal public street to an adjoining
property owned by a government or public utility to which vehicular access is restricted,
or other property to which vehicular access is restricted by a conservation easement; or
(4)
Require the extension or connection of a proposed internal public street to an adjoining
property that is developed or zoned for a use whose level and type of generated
traffic would be incompatible with the proposed development—provided, however, that
residential, institutional, and commercial uses shall generally be deemed compatible.
g.
Where a roadway is extended to, but not yet onto, adjoining land, a sign shall be installed
at the terminus of the roadway that informs neighboring property owners that the roadway is
intended to be extended in the future (e.g., ―STREET MAY BE EXTENDED BY AUTHORITY OF
THE TOWN OF MORRISVILLE‖). Notation of that intent shall also be included on the Major
Subdivision Preliminary Plat or Minor Subdivision Plat (see Section 2.5.6), Major Site Plan or
Minor Site Plan (see Section 2.5.7), and Construction Plan (see Section 2.5.8), as appropriate.
333
This provides a general requirement requiring proposed streets in a development to be stubbed to adjoining undeveloped or
underdeveloped properties where needed to ensure convenient neighborhood traffic circulation, access by police, fire, and public
service vehicles, or efficient provision of utilities.
