2-1-9: STREET NAMING STANDARDS:

2-1-9: STREET NAMING STANDARDS:
   A.   Street names shall conform to the following standards:
      1.   Any street, whether public or private, that provides access to two (2) or more addressed structures or properties must be officially named according to the provisions of this chapter.
      2.   Every street name shall include a pre-directional of North, South, East, or West, based on the street's direction of travel and its location relative to the initial point of the addressing grid in which it lies.
      3.   A street's pre-directional shall not change even if the street's direction changes. Streets that meander or are diagonal relative to the cardinal directions shall be treated as either a north-south or east-west street and the most appropriate pre-directional shall be used along the entire length of the street.
      4.   Every street name shall include one of the following post types:
         a.   Avenue: A north-south street generally running in a straight line.
         b.   Boulevard: A street that is eighty feet (80') wide or greater and which directional travel is separated by a raised median which is usually landscaped. The use of this term must be approved by ACHD.
         c.   Court: An east-west cul-de-sac.
         d.   Drive: A street generally meandering in an east-west direction.
         e.   Lane: A private road. Any street that will not be dedicated to ACHD, or another public entity is considered a private road and must be assigned this post type.
         f.   Place: A north-south cul-de-sac.
         g.   Road: A street that extends through both urban and rural areas. The use of this term must be approved by ACHD.
         h.   Street: An east-west street generally running in a straight line.
         i.   Way: A street generally meandering in a north-south direction.
         j.   Loop: A closed loop circular street that begins and circles back to terminate on the same street from which it begins
      5.   Street names shall not be more than thirteen (13) characters in length, including spaces, except when an existing street with a nonconforming name is to be extended.
      6.   Street names shall not contain the words North, South, East, or West or any combination thereof. Directionals shall only be used as pre-directionals (prefixes).
      7.   Proposed street names shall not duplicate existing names in spelling or pronunciation. Differentiation between existing and proposed names shall not be accomplished by changes in spelling or by the use of different pre-directionals or post types.
      8.   Proposed street names shall not sound alike or be easily confused with existing street names as determined by the county assessor.
      9.   Proposed street names shall not be vulgar, inappropriate, or profane as determined by the county assessor.
      10.   A cul-de-sac that has a length of one hundred feet (100') or less shall be given the same name and post type as the street from which it emerges. A cul-de-sac greater than one hundred feet (100') in length shall be given a different name than the street from which it emerges.
      11.   If a street makes an obvious change in direction, as determined by the county assessor, a new street name shall be assigned, except as herein provided for "L" shaped streets. The change in name shall occur as close as possible to the point where the direction changes.
      12.   Both portions of an "L" shaped street shall be assigned the same name if either leg is one hundred feet (100') or less in length, otherwise each leg shall be assigned a different name.
   B.   Street Alignments:
      1.   Where a proposed street is in general alignment with an existing street and is determined by the county assessor to be a continuation of that street, the existing street's name shall be continued to the proposed street. For a proposed street to be considered a continuation of an existing street, all the following will be considered:
         a.   Future development will likely extend the proposed street and/or the existing street segments, cause them to connect, or continue in an unbroken alignment.
         b.   Assigning the existing street name to the proposed street will not negatively impact the public safety or the delivery of public and/or private services.
         c.   The segments are separated by fifty feet (50') or less as measured perpendicularly to the direction of travel.
         d.   The segments are not situated in a manner that would cause duplication of address numbers across the segments.
         e.   The segments alignment or continuation is not broken by geographic features such as: rivers, canyons, and extreme topography.
      2.   Where a proposed street aligns with two (2) or more differently named streets, the street shall be given a new unique name unless it connects to one of the alignments.
      3.   Where a proposed street aligns with an existing street which has an incorrect post type, the proposed street shall be named with the correct post type. Except when a street connects to an incorrect post type, the original post type will take effect to maintain continuity.
      4.   Where a proposed street is private and a non-platted street and will not connect to an existing street; or is not in direct alignment of an existing street, a new unique name that adheres to the street naming standards will be required.
