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 70% of all the property owners. within the city limits as set forth in section § 91.49
(B)(4) supports the installation of speed humps. In gauging the level of support or opposition, the city will apply one “vote” per household. Joint or multiple property owners must sign to be counted. Unsigned owners on any petition or ballot will be counted as an opposition vote to the installation of speed humps. In the case of dual joint ownership, both owners must vote in the affirmative or the ballot will be counted as an opposition vote. In the case of multiple owners (more than two) of a particular property, a majority will determine the overall property vote.
(B) Location of the street. The land uses of the properties abutting the street where the speed hump is proposed must be composed of primarily residential dwellings. Only public roadways which have been accepted as part of the City’s roadway system may be considered.
(C) Operational characteristics of the street.
(1) The street must be used to provide access to abutting primarily 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 500 but less than 3,000 vehicles, two-way volume per day.
(4) The street must have a speed limit of no greater than 25 m.p.h.
(5) The appropriate fire district will review and comment, in writing, on all proposed speed hump locations. Should they identify significant concerns, which cannot be corrected, the city will not install speed humps.
(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 have 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.
