a. 
The provisions of this chapter which regulate speed, wake, and special use areas, as generally located on exhibits adopted pursuant to Article III, shall become operative upon the installation of signs designating those areas.
b. 
Pursuant to subdivision (a), the five-mile per hour speed zone on Georgiana Slough between the Oxbow Marina and the confluence with the Mokelumne River shall be operative only for those areas in which signs are installed pursuant to this subdivision. Signs designating an area as a five-mile per hour speed zone shall be installed 200 feet from existing docks or floating structures, and new docks or floating structures when they are built. Where docks are located more than 400 feet apart and less than 600 feet apart, the Sheriff may require installation of signs designating that area as a five-mile per hour speed zone, if the Sheriff finds that the distance between docks is not great enough for boats to increase and decrease without generating substantial wakes.
