All of the following criteria must be satisfied for a street to be considered eligible for speed hump installation.
(A) Petition. A petition that documents that a minimum of 75% of the property owners on a low density residential street (the entire length and any additional roadway primarily served by the street on which the hump will be located) supports the installation of speed humps.
(B) Location of the street. The land uses of the properties abutting the street where the speed hump is proposed must be composed of low density residential dwellings. This would include public roadways where 50% or more of the residences are single family detached housing.
(C) Operational characteristics of the street.
(1) The street must be used to provide access to abutting low density residential properties. The street must not be identified as a collector of higher level street, as defined by the Jefferson County Comprehensive Plan, Core Graphic 13.
(2) There must be no more than one moving lane of traffic in each direction.
(3) Traffic volumes must be more than 1,000 but less than 3,000 vehicles, two-way volume per day.
(4) Vehicle speed must exceed the speed criteria.
(5) The street must have a speed limit of 25 mph as determined in accordance with the city Code of Ordinances.
(6) The street must not be so close to a Fire Department facility as to significantly interfere with emergency vehicle operations.
(D) Geometric characteristics of the street.
(1) The street must have adequate sight distances to safely accommodate the hump as determined, in writing, by the city, as defined in the Traffic Engineering Handbook.
(2) The street must not have curves or grades that prevent safe placement of the humps. Humps may be located on streets that contain curves and/or grades, but the hump itself shall not be located within a significant horizontal curve, or a vertical grade greater than 8%.
(3) The street must be paved. If there are no curbs, a special design of speed hump must be used to prevent vehicles from going around the speed hump.
