Traffic calming elements shall be installed on all newly constructed streets in residential subdivisions. Traffic calming elements, as incorporated in County standard details adopted by the department, may include speed humps, speed tables, raised crosswalks, chokers, chicanes, roundabouts, mini-traffic circles, median or landscape treatments which facilitate pedestrian movement, special considerations for school zones and school routes, and any other elements or methods approved by the department. At a minimum, speed humps designed in accordance with the "Guidelines for the Design and Application of Speed Humps, ITE, 1993" shall be installed on minor collector streets as defined in section 18.04.030 of this title. Raised crosswalks using the Seminole County profile shall be installed at school or playground crossings on collector streets as defined in section 18.04.400 of this title. All acceptable traffic calming references, guidelines, standards and publications are on file with the department. This section shall not apply to any subdivision that has received preliminary plat approval between January 1, 2000, and the effective date of the ordinance. Subdivisions exempted under this provision that do not receive final plat approval by January 1, 2005, shall no longer be exempt and must comply with the requirements of this subsection. (Ord.
