The arrangements, character, extent, width,
grade and location of all streets shall conform to all applicable
street plans and standards officially adopted by the county or towns
and shall meet the following:
A. All streets shall be related to existing and planned
streets, existing natural features, public convenience and safety
and the existing and proposed uses for the land that is to be served
by such streets.
B. The arrangement of streets shall provide, where possible,
for the continuation or appropriate projection of existing collector
and arterial streets in the area.
C. Where adjoining areas are not subdivided, but may
be subdivided, the arrangement of streets in a new subdivision shall
make provision for the proper projection of streets into adjoining
areas by carrying the new streets to the boundaries of the new subdivision
at appropriate locations. Unbuilt private streets may have an access
easement dedicated to the county or other appropriate public body
as determined by the Land Management Committee. The street arrangements
shall not be such as to cause hardship to owners of adjoining property
in platting their own land and providing convenient access to it.
D. Where the land being divided abuts or contains an
existing or proposed arterial street, the Land Management Committee
may require marginal access streets, reverse frontage lots with a
planting screen contained in a nonaccess reservation along the rear
of the property line, deep lots with rear service alleys, or such
other treatment as may be necessary for adequate protection of residential
properties and to afford separation of through and local traffic.
E. Where the land being divided borders on or contains
a limited-access highway right-of-way, the Land Management Committee
may require a street approximately parallel to and on each side of
such right-of-way at a distance suitable for the appropriate use of
the intervening land. Such distances shall also be determined with
regard for the requirements of approach grades and future grade separations.
F. Half or partial streets are not permitted, except
to create a full street where the subdivision abuts an existing half
or partial street.
G. Dead-end streets shall be prohibited, except as stubs
to permit future street extension into adjoining tracts, or when designed
as cul-de-sac streets.
H. Construction of public roads shall be in accordance
with appropriate public road design standards.
I. Construction of private roads shall be in accordance
with appropriate town road design standards, unless waived by the
town in which the land division is proposed, in which case the Land
Management Committee shall specify standards for private road design
applicable to the particular land division.
J. Street names. All street names shall be as assigned
by the county in accordance with the uniform address numbering system.
When blocks are utilized, the following shall
apply:
A. The length, width and shape of blocks shall be appropriate
to the need for convenient access, control and safety of street traffic
and the limitations and opportunities of the topography.
B. Width. Blocks shall generally have sufficient width
to provide for two tiers of lots of appropriate depth, except one
tier of lots is sufficient where blocks abut a lake or stream, plat
boundary, or an arterial street.
C. Within blocks, pedestrian rights-of-way of at least
15 feet in width may be required by the Land Management Committee
to provide improved circulation or access to schools, playgrounds,
parks, shopping centers, waterways, and other community facilities.
D. Blocks adjoining arterial streets shall be so oriented
that the long dimension of the block shall front on the arterial street
in order to create as few intersections as possible along the arterial
street.
