A. The intent of this Section 6.4 is to promote safe roadways and to
prevent destructive or fatal accidents by ensuring adequate visibility
at intersections.
B. These regulations are effective whenever any development occurs or
any objects are placed or modified within the Sight Visibility Zone
as defined in this section.
(Ordinance 475 adopted 6/28/22)
A. The Sight Visibility Zone shall remain open and completely unobscured
as required by the Technical Manual within the area described by the
Technical Manual.
B. No development requiring a permit shall occur within the Sight Visibility
Zone at any height.
C. The Sight Visibility Zone shall be conveyed as an easement and indicated
on Plats, Subdivision Construction Plans and Site Plans.
D. Modified dimensions.
1.
Reduction. The City Engineer may reduce the required dimensions
in the Technical Manual if the reduction is necessary due to site-specific
constraints and does not negatively impact the safety of the intersection.
2.
Increase. The City Engineer may increase the required dimensions
in the Technical Manual if the increase is necessary due to site-specific
constraints and roadway speeds to ensure the safety at the intersection.
3.
Intersection sight distance. On a corner lot in any district,
nothing shall be erected, placed, planted, or allowed to grow in such
a manner that materially impair the Intersection Sight Distance (ISD)
as defined in the current edition of the American Association of State
Transportation Officials (AASHTO), A Policy on Geometric Design of
Highways and Streets; without approval of a variance by the City,
except that fences, walls, or hedges may be permitted provided that
such fences, walls, or hedges do not impair vision from three (3)
feet to six (6) feet above the curb line elevation.
4.
In accordance with Landscaping and Screening Standards in Article
5, and as permitted by the City Engineer:
(i)
Shrubs and hedges that are typically less than thirty inches
(30") in height at maturity, as measured from the centerline of the
street, may be located in the visual clearance areas of all districts.
(ii)
A limited number of single-trunk trees having a clear trunk
height of at least eight feet (8') may be located within sight visibility
areas provided that they are spaced and positioned such that they
will not produce a visibility inhibiting, "picket-fence" effect when
they attain mature size.
